Description

Technical Field

[0001] The present invention relates to the field of lighting, and in particular to a lighting device and applications thereof, wherein the illumination of the lighting device can be adjusted to multiple directions. Background Art

[0002] Lighting devices are tools that are often used in daily life and are needed in dark or gloomy environments.

[0003] The lighting direction of the lighting device can be adjusted according to the location of the use environment. For example, when a flashlight is held in the hand of a user, the user can rotate the direction of the lighting device as needed.

[0004] To free the user's hands, lighting devices typically come with a built-in stand or are secured in place via a support frame. To accommodate varying lighting directions, the light-emitting element and the stand are often adjustable. That is, the stand is fixed, and the light-emitting element can be adjusted relative to the stand, thereby changing the lighting direction of the entire lighting device.

[0005] However, for this type of lighting device, the lighting direction is usually adjustable in a single direction. For example, for a downward-facing or downward-adjustable lighting device, the light-emitting portion can be in an upward or downward-facing state. In this case, the rotating axis of the lighting device is usually in a horizontal position, allowing the entire lighting device to rotate around the horizontal rotating axis. Another common adjustment method is to adjust the lighting device to the right or left. In this case, the rotating axis is usually in a vertical position, allowing the entire lighting device to rotate around the vertical rotating axis.

[0006] A single lighting device can be adjusted to multiple directions during use, which is very convenient for users. Currently, in order to enable a single lighting device to be adjusted in multiple directions, the lighting device adopts a ball joint structure, so that the lighting device can be rotated more freely relative to the bracket to adjust the lighting angle.

[0007] The problem is that lighting devices, especially those used in industrial applications, typically require high light intensity, resulting in a large light-emitting portion. Consequently, the lighting device is heavy, and the ball joint structure sometimes struggles to support this heavy weight. Furthermore, the ball joint structure is typically located between the lighting device and the bracket. This means that users must bear the majority of the lighting device's weight to adjust the lighting angle.

[0008] If a spherical rotating joint is not adopted and instead multiple rotating shafts in different orientations are directly used to enable multi-directional adjustment of the lighting device, the structure of the entire lighting device will become complex or large, which is not conducive to later maintenance.

[0070] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variants. The basic principles defined in the following description of the present invention can be applied to other implementation schemes, variant schemes, improvement schemes, equivalent schemes, and other technical schemes that do not depart from the spirit and scope of the present invention.

[0071] Those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationship indicated by terms such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0072] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be construed as limiting the quantity.

[0073] Refer to the attached Figure 1A to the attached Figure 5 As shown, a lighting device 1 according to a preferred embodiment of the present invention is illustrated. The illumination direction of the lighting device 1 can be adjusted, and the illumination direction of the lighting device 1 can be adjusted to multiple different directions. It is worth mentioning that while the illumination direction of the lighting device 1 can be adjusted, the structure of the entire lighting device 1 is designed simply, thus realizing complex functions with a simple mechanical structure.

[0074] Specifically, the lighting device 1 includes at least one light-emitting component 10, a mounting component 20, and a supporting component 30. The light-emitting component 10 is used for emitting light, the mounting component 20 is used for mounting the light-emitting component 10, and the supporting component 30 is used for supporting the light-emitting component 10 and the mounting component 20.

[0075] The light-emitting component 10 is rotatably supported on the mounting component 20 relative to the mounting component 20, and the mounting component 20 is rotatably supported on the supporting component 30 relative to the supporting component 30. The light-emitting component 10 is supported on the supporting component 30 through the mounting component 20.

[0076] It is worth mentioning that the light-emitting component 10 and the mounting component 20 can be supported on the supporting component 30 in a suspended manner. The suspension here means that when the supporting component 30 is standing on a supporting surface, the mounting component 20 can be supported by the supporting component 30 without contacting the supporting surface. The supporting surface can be the ground, a tabletop, etc.

[0077] Further, the mounting component 20 includes a mounting housing 21, where the mounting housing 21 has a mounting top surface 211 and two mounting side surfaces 212. The two mounting side surfaces 212 are oppositely arranged, and the mounting side surfaces 212 respectively extend downward from at least part of the circumferential edge of the mounting top surface 211.

[0078] The mounting housing 21 has a mounting high end 213 and a mounting low end 214. The mounting high end 213 and the mounting low end 214 are oppositely arranged, and the mounting low end 214 extends downward from the mounting high end 213. The mounting top surface 211 and at least part of the mounting side surfaces 212 define the mounting high end 213.

[0079] The light-emitting component 10 is supported on the mounting high end 213 of the mounting housing 21 of the mounting component 20. The supporting component 30 is supported on the mounting side surfaces 212 of the mounting component 20.

[0080] The light-emitting component 10 is rotatably supported on the mounting high end 213 by at least part of the light-emitting component 10 around the mounting housing 21, and the mounting component 20 is supported in a pitch-motion manner on the supporting component 30.

[0081] Further, the lighting device 1 has at least one light-emitting axis A, where one light-emitting component 10 is rotatably supported on the mounting high end 213 around one light-emitting axis A. The lighting device 1 has a mounting axis B, where the mounting component 20 is rotatably supported on the supporting component 30 around the mounting axis B.

[0082] The light-emitting axis A passes through the mounting top surface 211 from top to bottom. The from top to bottom here does not mean that the light-emitting axis A must be in the vertical direction, but only means that the light-emitting axis A is from a higher position to a lower position and passes through the mounting top surface 211.

[0083] The support assembly 30 extends outwardly and downwardly from at least one of the mounting sides of the mounting housing 21.

[0084] Further, the support assembly 30 includes at least one support arm 31 and a support base 32. The support arm 31 extends outwardly and downwardly from a mounting side 212 to the support base 32, and the support base 32 supports the support arm 31 on the support surface. In this example, the number of support arms 31 is two, and the support arms 31 are respectively located on both sides of the mounting housing 21 of the mounting assembly 20. Each support arm 31 is respectively arranged to extend outwardly and downwardly from a corresponding mounting side 212, and the mounting housing 21 of the mounting assembly 20 is rotatably supported in a suspended manner on the support arms 31 of the support assembly 30.

[0085] The two mounting sides 212 are oppositely arranged. For the mounting assembly 20, the mounting assembly 20 can be stably supported on the support assembly 30 by the two support arms 31 respectively located on the mounting sides 212, and when the mounting assembly 20 pitches relative to the support assembly 30, the mounting assembly 20 can also be stably supported on the support assembly 30.

[0086] One light-emitting assembly 10 includes a mounting portion 11 and a light-emitting portion 12. One end of the mounting portion 11 is supported on the mounting high end portion 213 of the mounting housing 21, and the other end of the mounting portion 11 is a free end and supports the light-emitting portion 12.

[0087] The mounting portion 11 can be held on the mounting top surface 211 or the mounting side surface 212 of the mounting housing 21 of the mounting assembly 20 or other positions.

[0088] Further, the lighting device 1 has at least one accommodation space 100 and includes a lamp head assembly 40. The lamp head assembly 40 is located above the mounting housing 21 of the mounting assembly 20, and the accommodation space 100 is formed between the lamp head assembly 40 and the mounting housing 21.

[0089] The lamp head assembly 40 includes a handle 41 and a control portion 42. The handle 41 forms a holding space 410 for a user to pass through and hold the handle 41. The control portion 42 is arranged on the handle 41. The control portion 42 is used to control the light-emitting assembly 10, such as the on / off of the power supply to the light-emitting assembly 10. The control portion 42 may include a switch and corresponding interfaces.

[0090] At least a part of the mounting portion 11 of the light-emitting component 10 is held in the accommodation space 100 and is held in the accommodation space 100 by the light-emitting component 10 rotatably relative to the mounting housing 21 or the accommodation space 100.

[0091] It is worth mentioning that the lamp head component 40 is located above the mounting housing 21 of the mounting component 20, and at least a part of the mounting portion 11 of the light-emitting component 10 is located between the lamp head component 40 and the mounting housing 21, so that the overall structure of the entire lighting device 1 is relatively compact.

[0092] Furthermore, while the overall structure of the entire lighting device 1 is designed to be compact, it can also meet the requirement of changing the light illumination in multiple directions.

[0093] Specifically, the light-emitting component 10 can rotate relative to the mounting housing 21 of the mounting component 20, and the light-emitting component 10 can also rotate relative to the support component 30 through the rotation of the mounting housing 21 of the mounting component 20 relative to the support component 30, so that the light-emitting component 10 can rotate in multiple directions.

[0094] In other words, one light-emitting component 10 can rotate around the light-emitting axis A and can also rotate around the mounting axis B by being supported by the mounting housing 21.

[0095] The mounting axis B passes through the connection point of the support arm 31 and the mounting housing 21, and the light-emitting axis A passes through the connection point of the mounting portion 11 of the light-emitting component 10 and the mounting housing 21.

[0096] The light-emitting axis A passes through the mounting top surface 211 of the mounting housing 21 from top to bottom, and the mounting axis B passes through the mounting side surface 212 of the mounting housing 21.

[0097] The light-emitting axis A and the mounting axis B are in different directions, so that the position of the light-emitting component 10 can be adjusted in different directions, thereby adjusting the light illumination direction of the entire lighting device 1.

[0098] Furthermore, the light-emitting axis A simultaneously passes through the mounting high end portion 213 and the mounting low end portion 214 of the mounting housing 21 of the mounting component 20. That is to say, the light-emitting axis A is located in the extension direction from the mounting high end portion 213 to the mounting low end portion 214 or from the mounting low end portion 214 to the mounting high end portion 213.

[0099] Further, the light-emitting axis A and the mounting axis B are perpendicular to each other so that when the mounting axis B is a horizontal axis, the light-emitting axis A can be in a vertical direction when the mounting housing 21 of the mounting assembly 20 rotates to a certain position.

[0100] Of course, it can be understood that the light-emitting axis A and the mounting axis B can be in the same plane or in different planes.

[0101] On the other hand, the light-emitting assembly 10 can rotate about a first direction, and the mounting housing 21 of the mounting assembly 20 can rotate about a second direction. The first direction can be a direction extending between the mounting high end 213 and the mounting low end 214 of the mounting housing 21, and the second direction can be a direction extending between one mounting side 212 and the other mounting side 212. The first direction can be perpendicular to the second direction.

[0102] For the entire lighting device 1, the lighting device 1 can achieve light adjustment in multiple directions without a complex structural design.

[0103] Further, the light-emitting portion 12 of the light-emitting assembly 10 extends downward from one end of the mounting portion 11. The light-emitting portion 12 is supported by the mounting portion 11 in a suspended manner on the mounting housing 21 of the mounting assembly 20.

[0104] The light-emitting portion 12 has a light-emitting surface 121 that radiates light outward from the light-emitting surface 121. The projection of the light-emitting surface 121 in the height direction covers at least part of the mounting housing 21 of the mounting assembly 20. That is, the mounting portion 11 has a preset length so that one end of the mounting portion 11 is held in the accommodation space 100, and the other end of the mounting portion 11 - a free end is outside the accommodation space 100. Thus, the light-emitting portion 12 supported by the free end of the mounting portion 11 can extend downward for a longer distance without being blocked by the mounting housing 21 of the mounting assembly 20. Furthermore, the light-emitting portion 12 can be provided with a longer length. The light-emitting surface 121 can also be designed to be relatively large accordingly.

[0105] When the light-emitting assembly 10 rotates, the light-emitting portion 12 of the light-emitting assembly 10 can be located outside the mounting housing 21 of the mounting assembly 20, so that when the entire light-emitting assembly 10 rotates about the light-emitting axis A, the light-emitting portion 12 also rotates relative to the mounting housing 21 of the mounting assembly 20.

[0106] Further, the support arm 31 of the support assembly 30 is located outside the mounting housing 21 of the mounting assembly 20. The mounting portion 11 has a preset length so that the light-emitting portion 12 can maintain a certain distance from the support arm 31 of the support assembly 30. When the light-emitting assembly 10 rotates, the light-emitting portion 12 of the light-emitting assembly 10 is located outside the support arm 31 of the support assembly 30, so that when the entire light-emitting assembly 10 rotates around the light-emitting axis A, the light-emitting portion 12 also rotates relative to the support arm 31 of the support assembly 30.

[0107] In this way, when the light-emitting portion 12 rotates around the light-emitting axis A, the mounting housing 21 of the mounting assembly 20 and the support arm 31 of the support assembly 30 can prevent the light-emitting portion 12 from being blocked, so that the rotation angle of the light-emitting portion 12 can be designed to be larger.

[0108] It can be understood that the number of the light-emitting assemblies 10 can be one, two or more. In this example, the number of the light-emitting assemblies 10 is two, which does not limit the present invention.

[0109] One of the light-emitting assemblies 10 has a light-emitting axis A, and the other light-emitting assembly 10 has another light-emitting axis A. Preferably, the light-emitting axes A of the two light-emitting assemblies 10 are parallel to each other.

[0110] The accommodation space 100 is located above the mounting top surface 211, and the two light-emitting assemblies 10 are respectively supported on the mounting top surface 211 and accommodated in the accommodation space 100.

[0111] The light-emitting portion 12 of the light-emitting assembly 10 occupies a relatively large space, and the light-emitting portion 12 of each light-emitting assembly 10 is located outside the mounting housing 21 of the mounting assembly 20. During the rotation of the light-emitting portion 12, the rotation angle of one light-emitting assembly 10 is limited by the other light-emitting assembly 10.

[0112] In this example, when one light-emitting assembly 10 rotates to a position where its light-emitting portion 12 is adjacent to the light-emitting portion 12 of the other light-emitting assembly 10, the two light-emitting portions 12 are located in the same plane and can emit light outward simultaneously, so that the lighting device 1 can emit light with a relatively high brightness in the same direction. The two light-emitting assemblies 10 can also radiate light outward in different directions.

[0113] The rotation angle of the light-emitting assembly 10 is limited not only by the adjacent light-emitting assembly 10 but also by other factors.

[0114] Specifically, the lighting device 1 further includes a boss 50, where the boss 50 is located between the lamp head assembly 40 and the mounting assembly 20, and the accommodation spaces 100 are respectively formed on both sides of the boss 50 and are located between the lamp head assembly 40 and the mounting assembly 20.

[0115] In this example, the boss 50 includes a first part boss 51 and a second part boss 52, where the first part boss 51 is formed on the lamp head assembly 40 or is provided on the lamp head assembly 40, and the second part boss 52 is formed on the mounting assembly 20 or is provided on the mounting assembly 20.

[0116] When the lamp head assembly 40 is mounted on the mounting assembly 20, the first part boss 51 is supported by the second part boss 52. The first part boss 51 is provided to protrude downward at least partially from a lamp head bottom surface 421 of the lamp head assembly 40. The second part boss 52 is provided to protrude upward at least partially from the mounting top surface 211 of the mounting assembly 20.

[0117] Preferably, the size of a bottom surface of the first part boss 51 and the size of a top surface of the second part boss 52 are exactly the same, so that the first part boss 51 can be fully attached to the second part boss 52, which is beneficial to the lamp head assembly 40 being stably supported on the mounting housing 21 of the mounting assembly 20.

[0118] The boss 50 obstructs the rotation of the light emitting components 10 located on both sides of the boss 50. One light emitting component 10 can bypass the mounting side surface 212 from a front side of the mounting assembly 20 to reach a back side of the mounting assembly 20, and then cannot continue to rotate forward due to the limitation of the boss 50, and then return to the front side of the mounting assembly 20 along the original route.

[0119] Furthermore, in this example, the boss 50 is a cuboid, and the two light emitting components 10 are blocked by the boss 50. When one light emitting component 10 rotates towards the position of the boss 50, the boss 50 restricts the light emitting component 10 from continuing to rotate forward.

[0120] In this example, due to the limitation of the boss 50, the rotation angle of the light emitting component 10 does not exceed 180 degrees. The two light emitting components 10 are respectively rotatably connected to the mounting assembly 20 by 180 degrees or nearly 180 degrees. Preferably, the light emitting components 10 are symmetrically arranged on both sides of the boss 50.

[0121] Those skilled in the art can understand that the shape of the boss 50 and the rotation angle of the light-emitting component 10 described herein are only for illustrative purposes and do not limit the present invention.

[0122] It is worth mentioning that the illumination directions of the two light-emitting components 10 can be adjusted respectively. When adjusting the illumination direction of a single light-emitting component 10, the other light-emitting component 10 can be kept in a fixed position, or the illumination directions of the two light-emitting components 10 can be adjusted simultaneously.

[0123] It can be understood that the rotation angle of the light-emitting part 12 can be adjusted by the user according to needs. That is to say, the user can rotate the light-emitting part 12 to the expected position according to needs. It can also be that the adjustment angle of the light-emitting part 12 is fixed, for example, adjusted by 5 degrees each time.

[0124] In other words, the light-emitting part 12 of the light-emitting component 10 can be adjusted steplessly or stepwise relative to the mounting component 20.

[0125] It should be noted that in this example, the light-emitting surface 121 of the light-emitting part 12 faces away from the mounting component. The mounting part 11 of the light-emitting component 10 sweeps through an almost semi-circular area during rotation, and the light-emitting surface 121 is located in the circumferential direction. The light-emitting surface 121 can be tangent to the semi-circular area.

[0126] Specifically, when the light-emitting part 12 rotates with the mounting part 11, the irradiation direction of the light-emitting part 12 always faces outward, so that the lighting device 1 has a larger lighting area, which is especially suitable for lighting objects around the lighting device 1.

[0127] When the light-emitting component 10 rotates around the light-emitting axis A, light rays radiate outward from the light-emitting surface 121, and the light rays do not pass through the mounting housing 21 of the mounting component 20, so that the light rays are not blocked by the mounting housing 21 of the mounting component 20 and are radiated outward as much as possible.

[0128] The light-emitting surface 121 can be a flat surface or a curved surface. The light-emitting surface 121 can be a continuous flat surface, a discontinuous flat surface, a continuous curved surface, or a discontinuous curved surface.

[0129] The mounting part 11 can be a mounting arm, and the light-emitting surface 121 can be perpendicular to the mounting arm.

[0130] Of course, it can be understood that the light-emitting part 12 can also form other angles with the mounting part 11. Even the light-emitting surface 121 of the light-emitting part 12 can be located in an extending direction of the mounting part 11. When the light-emitting part 12 rotates, it can sweep through to form an annular area.

[0131] In another example of the present invention, the boss 50 is formed on or provided on the lamp head assembly 40. The mounting top surface 211 of the mounting housing 21 of the mounting assembly 20 is a flat surface. The height of the accommodating space 100 is determined by the height of the boss 50. The boss 50 is provided to protrude from the lamp head bottom surface 421 of the lamp head assembly 40. Optionally, the boss 50 is provided to protrude outward from the lamp head bottom surface 421 of the lamp head assembly 40.

[0132] In some other examples of the present invention, the boss 50 is formed on or provided on the mounting housing 21 of the mounting assembly 20. The lamp head bottom surface 421 of the lamp head assembly 40 is a flat surface. The height of the accommodating space 100 is determined by the height of the boss 50. The boss 50 is provided to protrude outward from the mounting top surface 211 of the mounting assembly 20. Optionally, the boss 50 is provided to protrude outward from an intermediate position of the mounting top surface 211 of the mounting housing 21 of the mounting assembly 20.

[0133] In some other examples of the present invention, the boss 50 is formed on the lamp head assembly 40, and at least part of the mounting top surface 211 of the mounting assembly 20 is recessed inward to accommodate at least part of the boss 50. When the lamp head assembly 40 is mounted on the mounting housing 21 of the mounting assembly 20, at least part of the boss 50 is exposed to form the accommodating space 100, and at least part of the boss 50 is accommodated in the mounting housing 21 of the mounting assembly 20.

[0134] Those skilled in the art can understand that the formation method of the accommodation space 100 is not limited to the above method. The formation of the boss 50 is also not limited to the above method. The shape of the boss 50 is not limited to a cube, and the cross-section of the boss 50 can be a square, a rectangle, a triangle, or a circle. Correspondingly, the shape of the boss 50 can be a cube, a cone, a cylinder, or other shapes. Correspondingly, the rotation angle of the light-emitting component 10 beside the boss 50 can exceed 180 degrees. For example, when the boss 50 is a cylinder, the light-emitting component 10 can be rotated to the side of the installation part 11 tangent to the surface of the boss 50 and the other side of the installation part 11 tangent to the surface of the boss 50 respectively.

[0135] According to some other embodiments of the present invention, the number of the light-emitting components 10 can be three, and the number of the accommodation spaces 100 can be three. At this time, the installation top surface 211 of the installation housing 21 of the installation component 20 can be a circle, and two adjacent ones of each installation part 11 of the three light-emitting components 10 can be rotatably installed on the installation housing 21 of the installation component 20 at equal distances.

[0136] It can be understood that the shape of the installation housing 21 of the installation component 20 is not limited to a rectangular shape, and can also be cylindrical, or prismatic.

[0137] Furthermore, the installation component 20 includes at least one connecting shaft 22. The installation housing 21 has a first installation hole 2111, a second installation hole 2112, and a third installation hole 2113, wherein the first installation hole 2111 and the third installation hole 2113 are respectively formed at the installation high end 213, and the second installation hole 2112 is located between the first installation hole 2111 and the third installation hole 2113.

[0138] Specifically, the first installation hole 2111, the installation hole 2112, and the third installation hole 2113 are respectively formed on the installation top surface 211.

[0139] One connecting shaft 22 is used to connect one light-emitting component 10 to the installation housing 21, and the other connecting shaft 22 is used to connect the other light-emitting component 10 to the installation housing 21.

[0140] Each installation part 11 of each light-emitting component 10 has an installation channel 110, wherein the installation channel 110 penetrates the installation part 11 in the height direction.

[0141] The first mounting hole 2111 corresponds to the mounting channel 110 of the mounting portion 11 of the light-emitting component 10, and the second mounting hole 2112 corresponds to the mounting channel 110 of the mounting portion 11 of the other light-emitting component 10.

[0142] One connecting shaft 22 passes through the mounting channel 110 of the mounting portion 11 of the light-emitting component 10, and then is inserted into the mounting housing 21 through the first mounting hole 2111. Another connecting shaft 22 passes through the mounting channel 110 of the mounting portion 11 of the other light-emitting component 10, and then is inserted into the mounting housing 21 through the third mounting hole 2113.

[0143] Each light-emitting portion 12 further has a connecting channel 120, at least a part of the connecting channel 120 is formed outside the mounting channel 110.

[0144] The two connecting channels 120 are respectively used for power supply wires to pass through. The wires can reach the light-emitting portions 12 through the connecting channels 120 and the connecting channels 120 respectively to supply power to the light-emitting portions 12.

[0145] The mounting housing 21 further has at least one side mounting hole 2120, one side mounting hole 2120 and another side mounting hole 2120 are respectively formed on the mounting side surface 212 of the mounting housing 21.

[0146] The support arm 31 of the support assembly 30 is rotatably connected to the mounting housing 21 of the mounting assembly 20, and the support arm 31 is mounted on the mounting housing 21 of the mounting assembly 20 through the side mounting hole 2120.

[0147] The light-emitting component 10 is axially connected to the mounting assembly 20, and the support arm 31 is axially connected to the mounting assembly 20. The position and formation method of the shaft are not limited to the above method.

[0148] Further, the support assembly 30 further includes a locking member 33, the locking member 33 is disposed in a support channel 310, and the support channel 310 is formed at one end of the support arm 31 connected to the mounting housing 21 of the mounting assembly 20.

[0149] For the entire lighting device 1, its weight mainly comes from the light-emitting component 10, the support component 30, and the mounting component 20. The support component 30 can suspend and support the light-emitting component 10 and the support component 30, and the locking member 33 can be disposed on the support arm 31 of the support component 30 to fix the support component 30 and the mounting component 20, so that the support component 30 and the mounting component 20 can be maintained in a fixed position.

[0150] More specifically, the locking member 33 is received in the support channel 310 of the support arm 31 and at least a part of the locking member 33 is exposed for user operation. The locking member 33 is engaged with the support arm 31 and the mounting housing 21. The locking member 33 has a locking state and an open state. In the open state, the relative position between the mounting component 20 and the support component 30 can be adjusted. In the locking state, the relative position between the mounting component 20 and the support component 30 is fixed. The locking member 33 is operably switched between the locking state and the open state.

[0151] In this example, the locking member 33 is rotatably received in the support channel 310 of the support arm 31 of the support component 30. The user can switch between the open state and the locking state by rotating the locking member 33.

[0152] Furthermore, the lighting device 1 includes a battery assembly 60. The mounting housing 21 of the mounting component 20 has a receiving cavity 200, and the battery assembly 60 is received in the receiving cavity 200.

[0153] The battery assembly 60 is respectively and power-supplyingly connected to each light-emitting component 10. It can be understood that the lighting device 1 of the present invention may not have the battery assembly 60. The lighting device 1 can be powered by a power interface through a wire, and the wire can be connected to a power supply device. The power interface can be located in the lamp head component 40.

[0154] When the lighting device 1 does not have the battery assembly 60, the control unit 42 and the power interface can be disposed in the receiving cavity 200 of the mounting housing 21 of the mounting component 20.

[0155] The battery assembly 60 is detachably connected to the mounting housing 21 of the mounting component 20 to facilitate the disassembly and replacement of the battery assembly 60.

[0156] Further, when the battery assembly 60 is installed in the installation housing 21 of the installation assembly 20, the opening 201 of the accommodation cavity 200 faces downward to reduce the possibility of moisture accumulating in the accommodation cavity 200 and thus entering the battery assembly 60.

[0157] The installation housing 21 of the installation assembly 20 has the installation high end 213 and the installation low end 214, where the installation high end 213 and the installation low end 214 are oppositely arranged, and the installation low end 214 extends downward from the installation high end 213.

[0158] The battery assembly 60 generally has a relatively large weight. The support assembly 30 is located at the installation high end 213 of the installation housing 21. After the battery assembly 60 is installed in the installation housing 21 of the installation assembly 20, it is beneficial to stably support the installation housing 21, the battery assembly 60, and the lighting assembly 10.

[0159] It is worth mentioning that after the battery assembly 60 is installed in the installation assembly 20, under the action of the self-gravity of the battery assembly 60 and the gravity of the installation assembly 20 and other components loaded on the installation assembly 20, the accommodation cavity opening 201 automatically faces downward to reduce the possibility of moisture entering.

[0160] It is worth mentioning that when the use environment is prone to water accumulation, the battery assembly 60 can be held at a relatively high position through the support base 32 to reduce the possibility of water entering the battery assembly 60. The support base 32 has at least one connection hole 320. The support base 32 can play the role of a medium. Through the support base 32, the lighting device 1 can be installed at other positions, such as a bracket, so that the lighting device 1 can adapt to different use heights. Through the connection hole 320, the support base 32 can be fixed to the bracket, and the support arm 31 is supported by the support base 32.

[0161] Optionally, the support base 32 can be integrally formed with the support arm 31 or can also be integrally formed with the support arm 31.

[0162] When the lighting device 1 needs to be used alone, the support base 32 can directly support on the ground. When the height of the lighting device 1 needs to be increased, the support base 32 can be installed on a bracket S, such as Figure 6 as shown, the use height of the lighting device 1 can be adjusted to meet different needs of users.

[0163] It is worth mentioning that the support base 32 can also be suspended from a ceiling W or other positions so that the lighting device 1 can be suspended for use. At this time, the lamp head assembly 40 and the support base 32 can be located on the same side. Refer to the attached Figure 7 As shown, the lighting device 1 can be suspended for use downward, and the light-emitting part 12 can also be adjusted by a certain angle relative to the mounting housing 21 of the mounting assembly 20.

[0164] Continue to refer to the attached Figure 1A to the attached Figure 5 As shown, in this example, the number of the connection holes 320 of the support base 32 is three, which is beneficial to the stable connection between the support base 32 and the bracket S. The positions and sizes of the connection holes 320 can be different to adapt to different installation environments.

[0165] Furthermore, preferably, the light-emitting assembly 10 can rotate about the light-emitting axis A in a vertical direction, and the mounting assembly 20 rotates about the mounting axis B in a horizontal direction.

[0166] It is worth mentioning that the wiring of the lighting device 1 is relatively simple, and the rotation of the light-emitting assembly 10 will not have too much impact on the wires.

[0167] The lamp head assembly 40 has at least one through hole, a first through hole 401, a second through hole 402 and a third through hole 403. One of the wires can pass through the first through hole 401 and then through the connection channel 120 of the mounting part 11, and then reach the first mounting hole 2111 of the mounting assembly 20 or reach the light-emitting part 12. One of the wires can pass through the second through hole 402 through the boss 50 and then reach the second mounting hole 2112 of the mounting part 11. One of the wires can pass through the third through hole 403 through the connection channel 120 of the mounting part 11, and then reach the third mounting hole 2113 of the mounting assembly 20 or reach the light-emitting part 12.

[0168] When the light-emitting assembly 10 rotates, the relative spatial positions of the first through hole 401, the corresponding connection channel 120 and the first mounting hole 2111 do not change, so that the wire can remain in a stable state when the light-emitting assembly 10 rotates. The relative spatial positions of the second through hole 402, the boss 50 and the third mounting hole 2113 do not change, so that the wire can remain in a stable state when the light-emitting assembly 10 rotates. The relative spatial positions of the third through hole 403, the connection channel 120 and the second mounting hole 2112 do not change, so that the wire can remain in a stable state when the light-emitting assembly 10 rotates.

[0169] When the mounting assembly 20 rotates relative to the support assembly 30, the electric wire can also be kept in a stable state.

[0170] It is worth mentioning that the overall structural design of the lighting device 1 is compact, such that it is possible to provide illumination in different directions simultaneously and achieve multi-directional adjustment of the illumination direction without the need for a complex structure.

[0185] According to some embodiments of the present invention, the light-emitting axis A passes through the mounting high end 213 and the mounting low end 214 respectively.

[0186] According to some embodiments of the present invention, the light-emitting axis A and the mounting axis B around which the mounting housing 21 rotates are perpendicular to each other.

[0187] According to some embodiments of the present invention, in the above method, when the light-emitting assembly 10 rotates about the light-emitting axis A, it bypasses the mounting housing 21.

[0188] According to some embodiments of the present invention, in the above method, when the light-emitting assembly 10 rotates about the light-emitting axis A, it bypasses the mounting housing 21 and the support assembly 30.

[0193] According to an embodiment of the present invention, the two light-emitting parts 12 are driven by the mounting housing 21 to move synchronously.

[0194] According to an embodiment of the present invention, the two light-emitting parts 12 move asynchronously.

[0195] According to an embodiment of the present invention, in the above steps, the mounting housing 21 includes the mounting portion 11 and the light emitting portion 12, wherein the light emitting portion 12 extends downward from the mounting portion 11.

[0196] According to an embodiment of the present invention, a light emitting surface 121 of the light emitting portion 12 faces away from the light emitting axis A.

[0197] According to an embodiment of the present invention, the light emitting surface 121 may be a curved surface or a flat surface.

[0198] Refer to the attached Figure 8 As shown, a modified embodiment of the lighting device 1 according to the present invention. In this example, the number of the light emitting components 10 is three.

[0199] The accommodation space 100 is formed between the lamp head assembly 40 and the mounting assembly 20. The mounting assembly 20 is a columnar structure, and the three light emitting components 10 are respectively held in the accommodation space 100, and the distance between adjacent light emitting components 10 is equal.

[0200] Each light emitting component 10 is pivotally connected to the mounting assembly 20 or the lamp head assembly 40, and the light emitting component 10 can rotate around the light emitting component 10 within a certain angle range.

[0201] Each light emitting component 10 can be individually controlled to meet different needs of users.

[0202] Refer to the attached Figure 9 As shown, a modified embodiment of the lighting device 1 according to the present invention is illustrated. In this example, the light emitting portion 12 is rotatably connected to the mounting portion 11.

[0203] The light emitting portion 12 is pivotally connected to the mounting portion 11 so that the light emitting portion 12 can rotate around the mounting portion 11. Thus, for the light emitting component 10, the light emitting portion 12 can rotate around the mounting assembly 20 through the mounting portion 11 or rotate around the mounting portion 11. In this way, the light irradiation direction of the lighting device 1 can be adjusted more flexibly.

[0204] The light emitting portion 12 may also be rotationally connected to the mounting portion 11 by a ball, and the light emitting portion 12 can be adjusted at multiple angles to make the adjustment direction of the light emitting portion 12 more diverse.

[0205] Refer to the attached Figure 10As shown, a modified embodiment of the lighting device 1 according to the present invention is illustrated. In this example, the light-emitting part 12 is movably connected to the mounting part 11 relative to the mounting part 11.

[0206] A guide rail is provided on the mounting part 11, wherein the guide rail is formed at the second end of the mounting part 11, and the light-emitting part 12 is slidably connected to the guide rail so that the light-emitting part 12 can move along the guide rail, thereby changing the relative position between the mounting part 11 and the light-emitting part 12, and further realizing the adjustment of the illumination direction of the lighting device 1.

[0207] Refer to the attached Figure 11 to the attached Figure 13 As shown, and referring to the attached Figure 1A and the attached Figure 1B , a lighting device 1 and its battery assembly 60 according to a preferred embodiment of the present invention are illustrated.

[0208] The lighting device 1 includes a lamp body 1000 and the battery assembly 60, wherein the battery assembly 60 is detachably mounted on the lamp body 1000, the lamp body 1000 has a receiving cavity and the battery assembly 60 is received in the receiving cavity. The battery assembly 60 is electrically connected to the lamp body 1000.

[0209] The battery assembly 60 provides electrical energy for the lamp body 1000, and when the energy in the battery assembly 60 is exhausted, the battery assembly 60 can be detached from the lamp body 1000 to replace it with a new battery assembly 60 full of electrical energy.

[0210] It is worth mentioning that the battery assembly 60 and the lamp body 1000 can be used separately, and the battery assembly 60 can be used as an independent power supply device. That is to say, the battery assembly 60 can not only supply power to the lamp body 1000, but also work for other devices that need to be driven by electricity, such as electronic devices like mobile phones and mobile laptops.

[0211] The battery assembly 60 can be used as an emergency power supply to provide electrical energy in time when it is difficult for users to obtain electrical energy.

[0212] The lamp body 1000 can be powered by a power cord from the power grid to work normally, and when the battery assembly 60 has insufficient power, it can also be charged through the power cord.

[0213] It is worth mentioning that the lamp body 1000 is designed in a certain structure so that enough space is provided for the battery assembly 60, enabling all components of the entire lighting device 1 to be designed more compactly to make the most effective use of space.

[0214] Specifically, the lamp body 1000 includes a lamp body main body 2000 and a mounting assembly 20, wherein the lamp body main body 2000 has a mounting space, and the mounting assembly 20 is received in the mounting space and the lamp body main body 2000 is mounted on the mounting assembly.

[0215] The mounting assembly 20 has a receiving cavity 200, and the receiving cavity 200 is used to receive the battery assembly 60.

[0216] The mounting space is located at an intermediate position of the lamp body main body 2000 to provide a receiving space for the battery assembly 60 having a relatively large size and weight. If the mounting space is located at the top end of the lamp body main body 2000, the battery assembly 60 being mounted at the top end of the lamp body main body 2000 may cause the center of gravity of the entire lighting device 1 to be unstable. If the mounting space is located at the bottom end of the lamp body main body 2000, when the lighting device 1 is placed on the ground, the battery assembly 60 may directly contact the ground, which is not conducive to the long-term use of the battery assembly 60 in harsh outdoor environments.

[0217] Furthermore, the mounting assembly 20 includes a mounting housing 21, wherein the mounting housing 21 has a mounting top surface 211, two mounting side surfaces 212, a mounting front surface, and a mounting back surface, wherein the mounting front surface and the mounting back surface are disposed opposite to each other, and the two mounting side surfaces 212 are disposed opposite to each other, and the mounting front surface is respectively connected to the two mounting side surfaces 212, the mounting front surface and the mounting back surface. Each of the mounting side surfaces 212 is respectively connected to the mounting front surface and the mounting back surface. When the lighting device 1 is placed on the ground for use, the mounting top surface 211 faces upward.

[0218] The mounting top surface 211, the mounting side surfaces 212, the mounting front surface, and the mounting back surface surround to form the receiving cavity 200 and the receiving cavity opening 201. The battery assembly 60 enters the receiving cavity 200 through the receiving cavity opening 201.

[0219] Furthermore, the lamp body main body 2000 includes at least one light emitting assembly 10, a support assembly 30, and at least one lamp head assembly 40, wherein the lamp head assembly 40 is supported by the mounting assembly 20, the light emitting assembly 10 is held between the lamp head assembly 40 and the mounting assembly 20, and the mounting assembly 20 can be supported by the support assembly 30. The lamp head assembly 40 and the light emitting assembly 10 are supported by the support assembly 30 through the mounting assembly 20.

[0220] Specifically, the lamp head assembly 40 is installed on the mounting assembly 20, and the lamp head assembly 40 is located on the mounting top surface 211 of the mounting assembly 20. The lamp body 2000 has at least one accommodation space 100, where the accommodation space 100 is formed between the lamp head assembly 40 and the mounting assembly 20, and at least part of the light emitting assembly 10 can be held in the accommodation space 100. The support assembly 30 is disposed at both ends of the mounting assembly 20.

[0221] The support assembly 30 includes two support arms 31, where the support arms 31 respectively extend outward from both sides of the mounting housing 21 of the mounting assembly 20. The two support arms 31 respectively support the mounting assembly 20.

[0223] The control part 42 is used to control the light emitting assembly 10, such as turning on and off the power supply to the light emitting assembly 10. The control part 42 may include a switch and corresponding interfaces.

[0224] In this way, the structure of the entire lamp head assembly 40 is designed to be relatively compact, with almost no waste of space. At the same time, the mounting assembly 20 can provide a relatively large space for installing the battery assembly 60.

[0225] Further, the lamp head assembly 40 has a plurality of through holes, a first through hole 401, a second through hole 402, and a third through hole 403, where the first through hole 401, the second through hole 402, and the third through hole 403 are respectively exposed on the lamp head bottom surface 421 of the lamp head assembly 40. The second through hole 402 is located between the first through hole 401 and the third through hole 403. The second through hole 402 is for a wire connecting the control part 42 of the lamp head assembly 40 and the battery assembly 60 installed on the mounting assembly 20 to pass through.

The electric wire for connecting the control part 42 and the battery component 60 passes through the second through hole 402 and the second installation hole 2112.

[0228] Each installation part 11 of the light emitting component 10 has an installation channel 110, where the installation channel 110 penetrates the installation part 11 in the height direction.

[0229] The first installation hole 2111 corresponds to the installation channel 110 of the installation part 11 of the light emitting component 10, and the second installation hole 2112 corresponds to the installation channel 110 of the installation part 11 of another light emitting component 10.

[0230] The installation component 20 further includes at least one connecting shaft 22.

[0231] Each light emitting part 12 further has a connecting channel 120, where at least part of the connecting channel 120 is formed outside the installation channel 110.

[0232] The two connecting channels 120 are respectively used for the power supply wire to pass through. The electric wire can reach the light emitting part 12 through the connecting channel 120 and the connecting channel 120 respectively to supply power to the light emitting part 12.

[0233] The installation housing 21 further has at least one side installation hole 2120, where one side installation hole 2120 and another side installation hole 2120 are respectively formed on the installation side surface 212 of the installation housing 21.

[0234] The support arm 31 of the support component 30 is rotatably connected to the installation housing 21 of the installation component 20, and the support arm 31 is installed on the installation housing 21 of the installation component

[0235] The light-emitting component 10 is pivotally connected to the mounting component 20, and the support arm 31 is pivotally connected to the mounting component 20. The position and formation manner of the pivot are not limited to the above manner.

[0236] Furthermore, the support component 30 further includes a locking member 33, wherein the locking member 33 is disposed in a support channel 310 formed at one end of the support arm 31 connected to the mounting housing 21 of the mounting component 20.

[0237] For the entire lighting device 1, its weight mainly comes from the light-emitting component 10, the support component 30, and the mounting component 20. The support component 30 can support the light-emitting component 10 and the support component 30 in a suspended manner, and the locking member 33 can be disposed on the support arm 31 of the support component 30 to fix the support component 30 and the mounting component 20, so that the support component 30 and the mounting component 20 can be maintained in a fixed position.

[0238] More specifically, the locking member 33 is received in the support channel 310 of the support arm 31 and at least a part of the locking member 33 is exposed for user operation. The locking member 33 engages with the support arm 31 and the mounting housing 21. The locking member 33 has a locking state and an open state. In the open state, the relative positions of the mounting component 20 and the support component 30 can be adjusted. In the locking state, the relative positions between the mounting component 20 and the support component 30 are fixed. The locking member 33 is operably switched between the locking state and the open state.

[0239] In this example, the locking member 33 is rotatably received in the support channel 310 of the support arm 31 of the support component 30. The user can switch between the open state and the locking state by rotating the locking member 33.

[0240] Furthermore, the lighting device 1 further includes a boss 50, wherein the boss 50, the mounting housing 21, and the lamp head assembly 40 define the accommodation space 100. The boss 50 includes a first part boss 51 and a second part boss 52, wherein the first part boss 51 is supported by the first part boss 51.

[0241] The lamp cap assembly 40 protrudes downward to form the first partial boss 51, where the first partial boss 51 is located on a bottom surface 421 of a lamp cap of the lamp cap assembly 40 and the first partial boss 51 is not located at an end of the bottom surface 421 of the lamp cap of the lamp cap assembly 40 so that the two accommodation spaces 100 can be respectively on two sides of the first partial boss 51. Preferably, the first partial boss 51 is formed at an intermediate position of the bottom surface 421 of the lamp cap of the lamp cap assembly 40.

[0242] When the lamp cap assembly 40 is mounted on the mounting assembly 20, the accommodation space 100 is formed between the bottom surface 421 of the lamp cap of the lamp cap assembly 40 and the mounting top surface 211 of the mounting assembly 20. The first partial boss 51 of the lamp cap assembly 40 is supported by the mounting assembly 20.

[0243] Further, the mounting assembly 20 protrudes upward to form the second partial boss 52, where the second partial boss 52 is located on the mounting top surface 211 of the mounting assembly 20 and the second partial boss 52 is not located at an end of the mounting top surface 211 of the mounting assembly 20 so that the two accommodation spaces 100 can be respectively on two sides of the second partial boss 52. Preferably, the second partial boss 52 is formed at an intermediate position of the mounting top surface 211 of the mounting assembly 20.

[0244] When the lamp cap assembly 40 is mounted on the mounting assembly 20, the accommodation space 100 is formed between the bottom surface 421 of the lamp cap of the lamp cap assembly 40 and the mounting top surface 211 of the mounting assembly 20. The first partial boss 51 of the lamp cap assembly 40 is supported by the second partial boss 52 of the mounting assembly 20.

[0245] In some other embodiments of the present invention, the bottom surface 421 of the lamp cap of the lamp cap assembly 40 is a flat surface, the second partial boss 52 is formed on the mounting top surface 211 of the mounting assembly 20, and the accommodation space 100 is formed in the mounting assembly 20.

[0246] In some other embodiments of the present invention, the mounting top surface 211 of the mounting assembly 20 is a flat surface, the first partial boss 51 is formed on the bottom surface of the lamp cap of the lamp cap assembly 40, and the accommodation space 100 is formed in the lamp cap assembly 40.

[0247] In some other embodiments of the present invention, the mounting top surface 211 of the mounting assembly 20 is recessed inwardly, the first part of the boss 51 is formed on the bottom surface 421 of the lamp head of the lamp head assembly 40, and the length of the first part of the boss 51 exceeds the depth of the recess of the mounting top surface 211 of the mounting assembly 20, and the accommodating space 100 is formed between the lamp head assembly 40 and the mounting assembly 20.

[0248] In some other embodiments of the present invention, the bottom surface 421 of the lamp head of the lamp head assembly 40 is recessed inwardly, the second part of the boss 52 is formed on the mounting top surface 211 of the mounting assembly 20, and the length of the second part of the boss 52 exceeds the depth of the recess of the bottom surface 421 of the lamp head of the lamp head assembly 40, and the accommodating space 100 is formed between the lamp head assembly 40 and the mounting assembly 20.

[0249] It can be understood that the formation manner of the accommodating space 100 described above does not limit the present invention.

[0250] The light emitting assembly 10 includes a mounting portion 11 and a light emitting portion 12, wherein at least a part of the mounting portion 11 is held in the accommodating space 100. The mounting portion 11 is for mounting the light emitting portion 12, the mounting portion 11 can be mounted on the mounting assembly 20, and the mounting portion 11 can also be mounted on the lamp head assembly 40. The light emitting portion 12 is used for emitting light outwardly.

[0251] Further, the mounting portion 11 is rotatably held in the accommodating space 100 relative to the lamp head assembly 40 or the mounting assembly 20. The light emitting portion 12 can rotate around the mounting assembly 20.

[0252] The support assembly 30 is pivotally connected to the mounting assembly 20, and the mounting assembly 20 is rotatably connected to the support assembly 30. For the user, the light emitting assembly 10 of the lighting device 1 can rotate forward and backward relative to the user as the mounting assembly 20 rotates relative to the support assembly 30.

[0253] The mounting portion 11 can be a mounting arm, wherein one end of the mounting arm is held in the accommodating space 100, the light emitting portion 12 is mounted on the other end of the mounting arm, and the mounting arm can rotate above the support assembly 30, and the light emitting assembly 10 is rotatably held in the accommodating space 100 by 180 degrees.

[0254] When the lighting device 1 is horizontally placed on the ground, the illumination range of the light-emitting component 10 can approximately cover 360 degrees in the horizontal plane and can provide lights in different directions. For example, when the two light-emitting components 10 are restored to side-by-side illumination after rotating 180 degrees horizontally from side-by-side illumination, the illumination range of each light-emitting component 10 is 180 degrees, and the illumination ranges of the two light-emitting components 10 are combined into 360 degrees.

[0255] Further, the light-emitting component 10 can also rotate relative to the support component 30 through the mounting component 20, so that the inclination angle of the light-emitting component 10 relative to the ground is changed, so that the light-emitting component 10 can rotate upward or downward.

[0256] In other words, the lighting device 1 has three rotating shafts, two of which are vertical rotating shafts, and each light-emitting component 10 can respectively rotate 180 degrees around one of the vertical rotating shafts, and the other is a horizontal rotating shaft, and the mounting component 20 can rotate a certain angle around the horizontal rotating shaft.

[0257] Further, it can be understood that the support component 30 can also be located on the front and back of the mounting housing 21 of the mounting component 20, and the support component 30 does not hinder the rotation of the light-emitting component 10.

[0258] The lamp head component 40 includes the handle 41 and the control part 42, wherein the control part 42 is arranged on the handle 41, and the control part 42 is used to control the light-emitting component 10, such as the on / off of the power supply of the light-emitting component 10. By operating the control part 42, the light-emitting component 10 can be turned on or off.

[0259] Further, in this example, the accommodation cavity opening 201 is formed downward in the mounting housing 21 of the mounting component 20. The battery component 60 is installed in the mounting housing 21 of the mounting component 20 through the accommodation cavity opening 201. Under the gravity of the battery component 60, the gravity of the lamp head component 40, and the gravity of the light-emitting component 10, the accommodation cavity opening 201 automatically faces downward. In this way, on the one hand, the battery component 60 is not exposed, thereby reducing the possibility of damage to the battery component 60, and on the other hand, the mounting housing 21 of the mounting component 20 can protect the battery component 60, especially in the top, side, front, and back orientations of the mounting housing 21 of the mounting component 20.

[0260] When the battery assembly 60 needs to be replaced, the installation housing 21 of the installation assembly 20 can be rotated to make the accommodation cavity opening 201 face a position convenient for user operation. After the user installs the new battery assembly 60 in the installation housing 21 of the installation assembly 20, the accommodation cavity opening 201 of the installation housing 21 of the installation assembly 20 automatically returns to the downward state.

[0261] Further, the lighting device 1 includes a guiding assembly 70, where the guiding assembly 70 includes a first guiding member 71 and a second guiding member 72. The first guiding member 71 is disposed on the installation housing 21 of the installation assembly 20, and the second guiding member 72 is disposed on the battery assembly 60. When the battery assembly 60 is aligned with the accommodation cavity opening 201 of the installation housing 21 of the installation assembly 20 and then pushed into the accommodation cavity 200, the second guiding member 72 on the battery assembly 60 moves inwards along the first guiding member 71.

[0262] The first guiding member 71 and the second guiding member 72 play a guiding role on the one hand and a limiting role on the other hand.

[0263] The first guiding member 71 and the second guiding member 72 respectively extend in the relative movement direction of the battery assembly 60 and the installation housing 21 of the installation assembly 20.

[0264] The first guiding member 71 is formed as an outward convex platform 50 from an inner wall of the installation housing 21 of the installation assembly 20, and the second guiding member 72 is formed as an inward depression from an outer wall of the battery assembly 60. When the battery assembly 60 is installed in the installation housing 21 of the installation assembly 20, the first guiding member 71 can enter the second guiding member 72.

[0265] In some other embodiments of the present invention, the first guiding member 71 is formed as an inward depression from the inner wall of the installation housing 21 of the installation assembly 20, and the second guiding member 72 is formed as an outward convex platform 50 from the outer wall of the battery assembly 60. When the battery assembly 60 is installed in the installation housing 21 of the installation assembly 20, the second guiding member 72 can enter the first guiding member 71.

[0266] The first guiding member 71 can be a convex platform 50, and the second guiding member 72 can be a groove. Alternatively, the first guiding member 71 can be a groove, and the second guiding member 72 can be a convex platform 50.

[0267] Furthermore, the lighting device 1 includes a battery locking assembly 80, where the battery locking assembly 80 includes a first locking member 81 and a second locking member 82. The first locking member 81 is disposed on the mounting housing 21 of the mounting assembly 20, and the second locking member 82 is disposed on the battery assembly 60. After the battery assembly 60 is mounted on the mounting housing 21 of the mounting assembly 20, the first locking member 81 located on the battery assembly 60 can be engaged with the second locking member 82 located on the mounting housing 21 of the mounting assembly 20.

[0268] The second locking member 82 includes a movable protrusion 821, an elastic member 822, and a button 823. The battery locking assembly 80 has an open state and a locked state. The movable protrusion 821 is supported by the elastic member 822 to maintain the locked state. In the locked state, the movable protrusion 821 can be locked to the first locking member 81, so that the battery assembly 60 cannot fall off the mounting housing 21 of the mounting assembly 20. In the open state, the movable protrusion 821 leaves the first locking member 81, so that the battery assembly 60 can be detached from the mounting housing 21 of the mounting assembly 20.

[0269] The movable protrusion 821 is controllably connected to the boss 50 to switch the movable protrusion 821 between the open state and the locked state.

[0270] The first locking member 81 is provided to protrude outward from the inner wall of the mounting housing 21 of the mounting assembly 20. When the movable protrusion 821 is in the locked state, the movable protrusion 821 is blocked by the protruding first locking member 81, so that the battery assembly 60 cannot fall off the mounting housing 21 of the mounting assembly 20.

[0271] Furthermore, the battery assembly 60 includes a battery 61 and a battery housing 62, where the battery housing is used to protect the battery 61.

[0272] The battery housing 62 of the battery assembly 60 has a battery housing top surface 621, a battery housing bottom surface 622, two battery housing side surfaces 623, a battery housing front surface 624, and a battery housing rear surface 625. The battery housing top surface 621 and the battery housing bottom surface 622 are oppositely arranged, the two battery housing side surfaces 623 are oppositely arranged, and the battery front surface 614 and the battery housing rear surface 625 are oppositely arranged.

[0273] The top surface 621 of the battery housing faces the mounting top surface 211 of the mounting housing 21 of the mounting assembly 20, the front surface 614 of the battery faces the mounting front surface of the mounting housing 21 of the mounting assembly 20, the back surface 625 of the battery housing faces the mounting back surface of the mounting housing 21 of the mounting assembly 20, and the side surface 623 of the battery housing faces the mounting side surface 212 of the mounting housing 21 of the mounting assembly 20.

[0274] In this example, the second locking member 82 is located on the front surface 624 or the back surface 625 of the battery housing of the battery assembly 60. When the second locking member 82 is located on the front surface 614 of the battery of the battery assembly 60, the first locking member 81 is located on the mounting front surface of the mounting housing 21 of the mounting assembly 20. When the second locking member 82 is located on the back surface 625 of the battery housing of the battery assembly 60, the second locking member 82 is located on the mounting back surface of the mounting housing 21 of the mounting assembly 20. The second locking member 82 and the first locking member 81 are respectively located at a preset position so that after the battery assembly 60 is mounted on the mounting housing 21 of the mounting assembly 20, the first locking member 81 and the second locking member 82 can cooperate with each other to prevent the battery assembly 60 from disengaging from the receiving cavity 200.

[0275] Refer to the attached Figure 14 shown, and at the same time refer to the attached Figure 1A 、attached Figure 1B as well as the attached Figure 11 to the attached Figure 13 According to a variant embodiment of the lighting device 1 of the above preferred embodiment of the present invention, the difference between this embodiment and the above embodiment mainly lies in the battery locking assembly 80.

[0276] The battery locking assembly 80 includes a first locking member 81 and a second locking member 82, wherein the first locking member 81 can be locked with the second locking member 82. When the battery assembly 60 is pushed into the receiving cavity 200 and after being pushed a certain distance, the battery assembly 60 is released and cannot disengage from the receiving cavity 200. At this time, the first locking member 81 and the second locking member 82 are locked with each other.

[0277] In this example, the first locking member 81 is provided on the battery assembly 60. The first locking member 81 is a boss, and the first locking member 81 is provided on the front surface 624 of the battery housing of the battery assembly 60.

[0278] The second locking member 82 is disposed on the mounting housing 21 of the mounting assembly 20, and the second locking member 82 includes a movable protrusion 821, an elastic member 822, and a button 823. The battery locking assembly 80 has an open state and a locked state, and the movable protrusion 821 is supported by the elastic member 822.

[0279] In the open state, the movable protrusion 821 protrudes from the inner wall of the mounting housing 21 of the mounting assembly 20 under the action of the elastic member 822. When the battery assembly 60 is mounted on the mounting housing 21 of the mounting assembly 20, the movable protrusion 821 in the open state is blocked by the first locking member 81, so that the battery assembly 60 cannot be detached from the receiving cavity 200.

[0280] In the closed state, the movable protrusion 821 moves toward the elastic member 822 under the action of the button 823 to compress the elastic member 822, and the movable protrusion 821 is away from the side surface 623 of the battery housing of the battery assembly 60, that is, away from the first locking member 81, so that the battery assembly 60 can be detached from the mounting housing 21 of the mounting assembly 20.

[0281] The movable protrusion 821 is controllably connected to the button 823. The user operates the button 823 to switch between the open state and the locked state of the movable protrusion 821.

[0282] Refer to the attached Figure 15 shown, which is a modified embodiment of the lighting device 1 according to the above embodiment of the present invention.

[0283] The difference between this embodiment and the above embodiment lies in the battery locking assembly 80.

[0284] The battery locking assembly 80 includes a first locking member 81 and a second locking member 82, wherein the first locking member 81 and the second locking member 82 cooperate with each other to lock the battery assembly 60 and the mounting housing 21 of the mounting assembly 20.

[0285] The battery locking assembly 80 has an open state and a locked state. In the open state, the first locking member 81 and the second locking member 82 are separated from each other. In the locked state, the first locking member 81 and the second locking member 82 are locked to each other.

[0286] The second locking member 82 is a groove and the second locking member 82 is formed on the mounting housing 21 of the mounting assembly 20. The first locking member 81 is a resilient sheet and one end of the resilient sheet is connected to the battery assembly 60, and the other end of the resilient sheet is a free end and extends from the accommodating cavity opening 201. The resilient sheet has a certain elasticity, and when not subjected to an external pressure, the resilient sheet protrudes from the surface of the battery assembly 60.

[0287] After the battery assembly 60 is mounted on the mounting housing 21 of the mounting assembly 20, at least a part of the first locking member 81 enters the second locking member 82, and the battery assembly 60 is blocked by the second locking member 82 and thus cannot be disengaged from the accommodating cavity 200.

[0288] When it is necessary to disassemble the battery assembly 60, the free end of the resilient sheet can be moved in a direction away from the battery assembly 60 so that the first locking member 81 is away from the second locking member 82, so that the battery assembly 60 can be disengaged from the accommodating cavity 200.

[0289] In some other embodiments of the present invention, the positions of the first locking member 81 and the second locking member 82 can be interchanged, that is to say, the first locking member 81 can be disposed on the mounting housing 21 of the mounting assembly 20, and the second locking member 82 can be disposed on the battery assembly 60.

[0290] Refer to the attached Figure 16 As shown, and at the same time refer to the attached Figure 1A attachment Figure 1B and attachment Figure 11 to attachment Figure 13 According to the above preferred embodiment of the present invention, a modified embodiment of the lighting device 1 is illustrated.

[0291] The difference between this embodiment and the above embodiment lies in the mounting housing 21 of the mounting assembly 20, the battery assembly 60, and the battery locking assembly 80.

[0292] The battery assembly 60 is directly detachably mounted on the mounting housing 21 of the mounting assembly 20.

[0293] The locking assembly includes a first locking member 81 and a second locking member 82, wherein the first locking member 81 is a threaded structure, the second locking member 82 is a threaded hole structure, wherein the second locking member 82 is disposed on the mounting housing 21 of the mounting assembly 20, and the first locking member 81 is disposed on the battery housing 62 of the battery assembly 60.

[0294] In this example, the accommodating cavity 200 of the mounting housing 21 of the mounting assembly 20 has a cylindrical structure, and the battery assembly 60 is arranged as a cylindrical structure. When the battery assembly 60 is connected to the mounting housing 21 of the mounting assembly 20 through screwing between the first locking member 81 and the second locking member 82, the battery assembly 60 can be detached from the mounting housing 21 of the mounting assembly 20 by rotating the battery assembly 60.

[0295] It is worth mentioning that the relative position between the mounting housing 21 of the mounting assembly 20 and the battery assembly 60 can be fixed. For example, when the battery assembly 60 is mounted on the mounting housing 21 of the mounting assembly 20 in a certain front-back order, the front side 624 of the battery housing of the battery assembly 60 and the mounting front side of the mounting housing 21 of the mounting assembly 20 are arranged face to face.

[0296] Furthermore, the mounting housing 21 of the mounting assembly 20 is designed as a waterproof structure so that when the battery assembly 60 is detachably mounted on the mounting housing 21 of the mounting assembly 20, the waterproof property at the connection between the battery assembly 60 and the mounting housing 21 of the mounting assembly 20 can be ensured.

[0297] With particular reference to Figure 17 to Figure 20 as shown, and also with reference to Figure 1A , Figure 1B and Figure 11 to Figure 13 it is worth mentioning that the lighting device 1 is a waterproof work lamp. The lighting device 1 further includes a waterproof component 90, and the waterproof component 90 can cooperate with the mounting housing 21 of the mounting assembly 20 to make the accommodating cavity 200 of the assembly 20 a waterproof cavity with certain waterproof performance.

[0298] The waterproof component 90 includes a first annular protrusion 91A and a first annular groove 91B, and the first annular protrusion 91A and the first annular groove 91B match each other. Here, the "annular" can be circular, triangular, rectangular or polygonal, etc.

[0299] The first annular protrusion 91A is arranged to extend outward from the bottom surface 421 of the lamp head of the lamp head assembly 40, and the first annular groove 91B is arranged to be recessed inward from the top surface 211 of the mounting housing 21 of the mounting assembly 20. When the lamp head assembly 40 is mounted on the mounting housing 21 of the mounting assembly 20, the first annular protrusion 91A fits against the first annular groove 91B to prevent moisture from entering the connection between the lamp head assembly 40 and the mounting housing 21 of the mounting assembly 20. For details, please refer to the attached Figure 18A , which is an enlarged schematic view of the first annular protrusion 91A and the first annular groove 91B at the positions of the first part boss 51 and the second part boss 52.
