Description

Technical Field

[0001] The embodiments of the present application belong to the field of lighting technology, and specifically relate to an LED floodlight. Background Art

[0002] At present, most LED lamps have a single luminous angle when they leave the factory. The lighting needs are usually adjusted by adjusting the color temperature and power, resulting in a single application scenario for the lamps. There are also methods that adjust the lighting angle by adjusting the projection angle of the light source component, but this adjustment is too simple and crude with poor accuracy, making it difficult to achieve ideal lighting needs. There are also methods that switch between lenses with different luminous angles by moving the light-emitting module, but because the light-emitting module needs to be connected to structures such as the power supply, its structure is relatively complex, and the accuracy of adjustment and long-term reliability cannot be effectively guaranteed.

Specific embodiments

[0038] Please refer to Figure 1 , is a schematic exploded view of a three-dimensional structure of an LED floodlight according to an embodiment of the present application. The LED floodlight includes a lamp body 10, a light-emitting module 20, a lens 30 and a rotating assembly 40.

[0039] Please combine Figure 2-8The lamp body 10 includes a light source compartment 110 and a power supply compartment 120, and the light source compartment 110 and the power supply compartment 120 are respectively arranged at two opposite ends of the lamp body 10, and the openings of the light source compartment 110 and the power supply compartment 120 are opposite; the light emitting module 20 includes a lamp board 210 and LED lamp beads 220 arranged in a row on the lamp board 210, and the side of the lamp board 210 away from the LED lamp beads 220 is connected to the bottom 1101 of the light source compartment 110; the lens 30 is arranged on the side of the light emitting module 20 away from the bottom 1101 of the compartment, and includes multiple The lens areas 310 are interconnected, and each of the lens areas 310 includes at least two rows of lens units 320, and the two adjacent rows of lens units 320 have different luminous angles. Each of the lens areas 310 has a row of lens units 320 corresponding to the LED lamp beads 220; the rotating component 40 is arranged on the bottom 1101 of the warehouse, and one end passes through the light board 210 and is connected to the lens 30. By rotating the rotating component 40, the lens 30 can be driven to move, so that the lens units 320 with different luminous angles correspond to the LED lamp beads 220.

[0040] Specifically, the light source compartment 110 and the power supply compartment 120 are separated at the two ends of the lamp body 10 and are respectively located on both sides of the lamp body 10, that is, the light source compartment 110 is opened downward and is located on the lower side of the lamp body 10, and the power supply compartment 120 is opened upward and is located on the upper side of the lamp body 10. In order to conveniently display the structure in the light source compartment 110, the lamp body 10 is inverted in the figure; a plurality of LED lamp beads 220 are arranged in an array on the lamp board 210, and a light-emitting surface is formed when the lamp beads 220 are lit. The side of the lamp board 210 facing away from the lamp beads 220 is connected to the bottom 1101 of the light source compartment 110, and its specific connection method is Including but not limited to a detachable connection by screws; the lens 30 is arranged on the side of the light board 210 away from the bottom 1101 of the bin, but it is not fixedly connected, but can slide back and forth on the light board 210, and the multiple lens areas 310 can be regarded as artificially dividing the lens 30 into multiple areas, which are lined up and connected to each other, but in fact these areas are connected into a whole, and each lens area 310 includes at least two rows of lens units 320, and each row of lens units 320 has a number of single lenses. Here, the number of the lens areas 310 of the lens 30, and the number of each lens area 310 are as follows: The number of rows of the lens units 320 in each lens area 310 and the number of single lenses in each row are not limited here. It can be imagined that it is related to the size of the lamp board 210 below, the layout of the lamp beads 220, the size of the light source compartment 110 and the specifications of the LED floodlight. Each of the lens areas 310 has a row of lens units 320 corresponding to a row of LED lamp beads 220 on the lamp board 210 below it. By sliding the lens 30 back and forth on the lamp board 210, it is possible to switch between lens units 320 with multiple different luminous angles, thereby changing the luminous angle of the LED floodlight; The rotating component 40 is embedded in the bottom 1101 of the bin of the lamp body 10, with one end being a rotating operating end placed outside the lamp body 10, and the other end being a connecting end passing inward through the lamp board 210 to be connected to the lens 30. By rotating the operating end outside the lamp body 10, the lens 30 can be driven to move. The specific moving direction is as indicated by the arrow in the figure, that is, perpendicular to the direction of the lens units 320 arranged in rows, so that the lens units 320 with different luminous angles correspond to the LED lamp beads 220 below them, thereby realizing fast and precise adjustment of the luminous angle of the lamp, ensuring that more ideal lighting needs can be achieved in different lighting environments.

[0041] Furthermore, in other preferred embodiments of the present application, each of the lens areas 310 includes a first lens unit and a second lens unit with different light-emitting angles, and a plurality of the first lens units and a plurality of the second lens units are arranged alternately.

[0042] Specifically, in this embodiment, adjustment of two different light-emitting angles can be achieved. The light-emitting angles of the first lens unit and the second lens unit are different. Multiple first lens units and multiple second lens units are arranged alternately with each other. For example, the odd-numbered rows of the lens 30, such as the 1st, 3rd, 5th, 7th, etc., are the first lens units, and the even-numbered rows, such as the 2nd, 4th, 6th, 8th, etc., are the second lens units.

[0043] In other preferred embodiments of the present application, each of the lens areas 310 includes three, four or even more lens units 320 with different luminous angles. By rotating the rotating component 40, the lens 30 can be driven to move, so that the lens units 320 with different luminous angles correspond to the LED lamp beads 220 thereunder, thereby achieving better adjustment of the luminous angle to ensure that more ideal lighting requirements can be achieved in different lighting environments.

[0044] Furthermore, in other preferred embodiments of the present application, the rotating assembly 40 includes an eccentric wheel 410 and a handle 420;

[0045] The eccentric wheel 410 is disposed at the bottom 1101 of the chamber. A rotating protrusion 4101 is provided on the eccentric wheel 410. The rotating protrusion 4101 passes through the lamp body 10 and is accommodated in the first sliding hole 301 of the lens 30 on the side close to the power supply chamber 120.

[0046] The handle 420 is connected to an end of the eccentric wheel 410 away from the rotating protrusion 4101 and is placed outside the lamp body 10 .

[0047] Specifically, the bottom 1101 of the bin has a through hole for accommodating the eccentric wheel 410, and the eccentric wheel 410 can rotate in the through hole. The rotating protrusion 4101 is arranged on the edge of the surface of the eccentric wheel 410 above the bottom 1101 of the bin. It is emphasized here that the rotating protrusion 4101 is not close to the center of the circle, that is, it constitutes the eccentric wheel. The end of the rotating protrusion 4101 passes through the through hole on the lamp board 210 and is accommodated in the first sliding hole 301. The first sliding hole 301 here is located on the side of the lens 30 close to the power supply bin 120. The handle 420 is provided at the end of the eccentric wheel 410 away from the rotating protrusion 4101. The handle 420 here is placed outside the lamp body 10 for easy operation. When in use, it is only necessary to rotate the handle 420, and the handle drives the eccentric wheel 410 to rotate. The rotation of the eccentric wheel 410 drives the rotating protrusion 4101 to move in the first sliding hole 301, thereby pushing the lens 30 to slide above the lamp board 210.

[0048] Furthermore, in other preferred embodiments of the present application, a boss 1102 is provided on the lamp body 10 at the periphery of the handle 420 ;

[0049] The boss 1102 is provided with a waterproof cover 1103 for housing the rotating assembly 40 therein.

[0050] Specifically, the boss 1102 is located on the periphery of the through-hole of the compartment bottom 1101 for inserting the handle 420, and is integrally formed with the lamp body 10. The waterproof cover 1103 is disposed on the boss 1102. The waterproof cover 1103 is used to cover the boss 1102, thereby protecting the rotating assembly 40 and providing waterproofing. The connection between the waterproof cover 1103 and the boss 1102 includes, but is not limited to, a detachable connection via a connecting ring 1104 on the top of the waterproof cover 1103 inserted into the through-hole of the boss 1102.

[0051] Furthermore, a groove 1105 is provided on the side of the waterproof cover 1103 facing the boss 1102, and a sealing ring 1106 is also provided in the groove 1105. Here, the sealing ring 1106 can make the connection between the waterproof cover 1103 and the boss 1102 more compact, further improving the waterproof performance of the lamp body 10.

[0052] Furthermore, in other preferred embodiments of the present application, the LED floodlight also includes a lens pressing plate 50 for pressing the lens 30, and the lens pressing plate 50 is connected to the end of the bin bottom 1101 away from the power supply bin 120, and has a first inclined surface 510 facing the bin bottom 1101, and the side of the lens 30 away from the power supply bin 120 is provided with a second inclined surface 330 matching the first inclined surface 510.

[0053] Specifically, the lens pressing plate 50 is pressed on the side of the lens 30 opposite to the first through hole 301 in the direction of the arrow as shown in the figure, the first inclined surface 510 is arranged toward the lens 30, and the second inclined surface 330 is arranged on the side of the lens 30 opposite to the first through hole 301, and the second inclined surface 330 is arranged in the opposite direction toward the lens pressing plate 50, the first inclined surface 510 and the second inclined surface 330 match each other, and the second inclined surface 330 can follow the movement of the lens 30 to extend under the first inclined surface 510 or extend from under the first inclined surface 510. Here, the lens pressing plate 50 and the matching first inclined surface 510 and second inclined surface 330 can prevent the lens 30 from warping and deforming during reciprocating movement, causing the angle to change.

[0054] Furthermore, in other preferred embodiments of the present application, the lens 30 is further provided with a plurality of second sliding holes 302 , and the plurality of second sliding holes 302 are spaced and distributed on the side edges of the lens 30 on both sides of the first sliding hole 301 ;

[0055] Limiting columns 303 are provided in the second sliding holes 302 located on both sides of the middle of the lens 30; the other second sliding holes 302 are used to accommodate the nuts 2101 for fixing the light board 210 or for the screws 304 for connecting the lens 30 to pass through.

[0056] Specifically, a plurality of second sliding holes 302 are provided on both sides of the lens 30 along the sliding direction of the lens 30, wherein the second sliding hole 302 located in the middle is provided with the limiting column 303, the bottom of the limiting column 303 is connected to the bottom 1101 of the bin, and the top is accommodated in the second sliding hole 302, so as to limit the position of the lens 30 when it slides and prevent it from moving to the left and right directions, thereby causing the light-emitting angle to change; in addition, the second sliding holes 302 located on the front and rear sides of the limiting column 303 are respectively used The second sliding hole 302 is used to accommodate the nut 2101 for fixing the light board 210, or to allow the screw 304 for connecting the lens 30 to pass through. That is, the height of the nut 2101 here is lower than the depth of the second sliding hole 302, and the screw 304 passes through the second sliding hole 302. A nail cap with a diameter greater than the width of the second sliding hole 302 is provided at the end of the screw to limit the vertical direction of the lens 30, preventing the distance between the lens 30 and the light board 210 from changing during the sliding process, which would cause the luminous angle of the lens 30 to change.

[0057] Furthermore, in other preferred embodiments of the present application, a convex rib 305 is provided on the side of the lens 30 facing away from the light board 210 , and the convex rib 305 surrounds the entire lens area, the first sliding hole 301 and the second sliding hole 302 .

[0058] Specifically, the rib 305 is arranged around the periphery of the entire lens area, as well as around the periphery of the first sliding hole 301 and the second sliding hole 302. The rib 305 here can, on the one hand, enhance the overall strength of the lens 30 so that it will not deform when subjected to force and moves, thereby ensuring the accuracy of its light-emitting angle; on the other hand, it can increase the depth of the first sliding hole 301 and the second sliding hole 302 to a certain extent to facilitate their accommodation of the rotating protrusion 4101 and the nut 2101; in addition, it can also reduce the contact area between the lens 30 and the structure above it when sliding, reduce the friction force of the lens 30 when sliding, and make it slide more smoothly.

[0059] It should be noted that both the first sliding hole 301 and the second sliding hole 302 are elongated, track-shaped holes. This design facilitates the sliding of the lens 30. The sliding lengths of the first sliding hole 301 and the second sliding hole 302 are related to the sliding travel of the lens 30, and should be set accordingly for different lamp sizes. The widths of the first sliding hole 301 and the second sliding hole 302 should be adjusted based on the internal accommodation structure.

[0060] Furthermore, in other preferred embodiments of the present application, a power supply 60 is provided in the power supply compartment 120, and the bottom 1101 of the compartment is provided with a wire threading hole 1107 which is connected to the power supply compartment 120 and through which a cable electrically connecting the power supply 60 and the light board 210 passes.

[0061] Specifically, the power supply 60 is fixed and detachably connected to the power supply compartment 120 through a power supply fixing plate. The specific connection method includes but is not limited to connection through screws. The power supply 60 is electrically connected to the light board 210 in the light source compartment 110 through a cable, thereby providing power support therefor, and the wire holes 1107 for the cable to pass through are respectively provided at the two corners of the bottom 1101 of the compartment.

[0062] Furthermore, in other preferred embodiments of the present application, the LED floodlight further includes a reflector 70, a mask 80 and a cover ring 90;

[0063] The reflector 70 is disposed in the light source compartment 110, with one end disposed on the lens 30 and the other end connected to the compartment wall of the light source compartment 70;

[0064] The face shield 80 is disposed on a side of the reflector 70 facing away from the lens 30 and is pressed and connected to the light source chamber 110 through the cover ring 90 .

[0065] Specifically, the reflector 70 is trumpet-shaped, with one end being transparent and the other end being larger. The smaller end is positioned on the lens 30, specifically on the rib 305 above the lens 30, while the larger end is positioned on the wall of the light source compartment 110. The face shield 80 covers the end of the larger end of the reflector 70, forming a relatively enclosed storage space with the reflector 70 and the lens. The face shield 80 may be made of, but is not limited to, transparent glass. The cover ring 90 is fastened to the top of the light source compartment 110 and is screwed through the other side of the lamp body 10 to connect to the light source compartment 110, thereby press-fitting the face shield 80 to the light source compartment 110.

[0066] Furthermore, in other preferred embodiments of the present application, in order to ensure the tightness of the connection between the light source compartment 110 and the mask 80 and improve the waterproof performance of the LED floodlight, a rubber ring 801 is further provided between the top of the light source compartment 110 and the mask 80, and the material of the rubber ring 801 includes but is not limited to silicone material.

[0067] Furthermore, in other preferred embodiments of the present application, a gap 910 is provided between the light source compartment 110 and the power supply compartment 120 for screws to pass through to fix the cover ring 90, a screw hole 9101 is provided at the bottom of the gap 910, and drainage holes 9102 are provided on both sides of the screw hole 9101.

[0068] Specifically, the light source compartment 110 and the power supply compartment 120 are not tightly connected together, but have the gap 910. The gap 910 can separate the heating elements inside the two (the light-emitting module 20 and the power supply 60), avoid heat accumulation, help separate the heat dissipation, and thus improve the overall heat dissipation efficiency of the LED floodlight; the screw hole 9101 for fixing the cover ring 90 is provided at the bottom of the gap 910, that is, the screw can pass through the screw hole 9101 from the back of the lamp body 10 to connect with the cover ring 90 on the front of the lamp body 10; here, the drainage holes 9102 for drainage are respectively provided on both sides of the screw hole 9101 at the bottom of the gap 910. The drainage holes 9102 here can quickly discharge rainwater and the like entering the gap 910, thereby ensuring the safety of the LED floodlight.

[0069] Furthermore, the bottom of the gap 910 is not completely flat, but has a certain slope, that is, the height of the position away from the drainage hole 9102 is higher than the height of the position close to the drainage hole 9102, so that multiple drainage channels flowing to the drainage hole 9102 are formed in the gap 910. Such a design can accelerate the drainage of rainwater in the gap 910, further improving the safety of the use of the LED floodlight.

[0070] It should be understood that the terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a," "the," and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, and unless the context clearly indicates otherwise, "a plurality" generally includes at least two, but does not exclude the inclusion of at least one.

[0071] It should be understood that the term "and / or" as used herein simply describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "the first component and / or the second component" can represent three situations: the first component exists alone; the first component and the second component exist simultaneously; and the second component exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0072] It should be understood that although the terms "first," "second," "third," etc. may be used to describe certain components in the embodiments of the present application, these components should not be limited to these terms. These terms are only used to distinguish the components from each other. For example, without departing from the scope of the embodiments of the present application, the first "such-and-such" component may also be referred to as the second "such-and-such" component, and similarly, the second "such-and-such" component may also be referred to as the first "such-and-such" component.

[0073] Depending on the context, the words "if" and "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to monitoring." Similarly, depending on the context, the phrases "if it is determined" or "if (stated condition or event) is monitored" may be interpreted as "when it is determined" or "in response to determining" or "when monitoring (stated condition or event)" or "in response to monitoring (stated condition or event)."

[0074] In the embodiments of this application, terms such as "substantially equal to," "substantially perpendicular to," or "substantially symmetrical" mean that the macroscopic dimensions or relative positional relationship between the two features closely approximates the relationship described.
