Description

Technical Field

[0001] The present invention relates to the technical field of lighting devices, and more specifically, to a lighting lamp that can be rotatably fixed to a cylindrical bracket with a support plate. Background Art

[0002] A portable lighting lamp refers to a lighting device that is convenient to carry and move. Such lighting lamps are usually small in size, light in weight, and easy to operate, and are suitable for use in outdoor activities, emergencies, camping, night reading, or other occasions that require temporary lighting.

[0003] In order to enable users to use it with their hands free in different scenarios, the design of portable lighting lamps often needs to consider the stability of their own structure and whether they can be conveniently fixed to other objects. The portable lighting lamp disclosed in the Chinese patent with the publication number CN219433104U and the patent name "A Portable Mobile LED Decorative Cylindrical Lamp" includes a base bottom cover, a first base upper cover, a second base upper cover, a first base connecting piece, a second base connecting piece, a circular aluminum sleeve, a switch button, a driving board, a tripod aluminum base, a light strip, an inner tube, an outer tube, and a top cover. Among them, the upper end of the base bottom cover is installed with the first base upper cover and the second base upper cover through screws, and the first base upper cover and the second base upper cover are clamped. In addition, a first counterweight and a second counterweight are placed on the upper end of the base bottom cover 1. The number of the second counterweights is two, and the two second counterweights are in contact with each other, and both second counterweights are in contact with the first counterweight. The first counterweight and the second counterweight are in contact with the first base upper cover and the second base upper cover.

[0004] Through the design of the first counterweight and the second counterweight in the portable lighting lamp with the above structure, and the first counterweight and the second counterweight can be freely combined to meet the counterweight needs in different overall scenarios. However, this design only considers whether the lighting lamp can maintain stability in a single placement scenario. However, when used in some scenarios, users need to project the light onto the ground to prevent the formation of dark areas around the lighting lamp. This makes the lighting lamp also used in an inverted state. At this time, the first counterweight and the second counterweight obviously cannot play a counterweight role. At this time, it is often necessary to use a cylindrical bracket for support. Figure 1 Shown is a cylindrical bracket 10 that exists on the current market and can support the lighting lamp when it is used in an inverted state. A number of support plates 1001 are distributed in a ring on the inner wall of the cylindrical bracket 10. After inserting the lighting lamp into the inner part of the cylindrical bracket 10, the support plates 1001 support the base bottom cover part of the lighting lamp. However, even with the support of the cylindrical bracket 10, the above-mentioned lighting lamp is still prone to rotate relative to the cylindrical bracket 10, and is prone to separate from the cylindrical bracket 10 when subjected to an accidental force in the axial direction of the cylindrical bracket 10, causing falling damage, and at the same time, it will also cause the lighting lamp to be unable to maintain a fixed lighting direction, affecting the user's line of sight and lighting effect. Summary of the Invention

[0005] In view of the above situation, in order to overcome the problem that the existing portable lighting lamp can only maintain stability in a single placement scenario, and when it is inverted and used in cooperation with a cylindrical bracket, the lighting lamp is prone to rotate relative to the cylindrical bracket, and is also prone to separate from the cylindrical bracket when subjected to an accidental force in the axial direction of the cylindrical bracket, resulting in falling damage, and at the same time, it will also cause the lighting lamp to be unable to maintain a fixed lighting direction, affecting the user's line of sight and lighting effect, the purpose of the present utility model is to provide a lighting lamp that is not easily deflected and not easily separated when used in cooperation with a cylindrical bracket, so as to relatively stably maintain the lighting direction, and significantly improve the lighting effect and user experience.

It is only for the convenience of simplifying the description, rather than indicating or implying that this orientation is a specific orientation that must be possessed and specific orientation structures and operations. Therefore, it should not be construed as a limitation to the present invention.

[0038] Embodiment 1:

[0039] As Figures 1 to 4 shown, the present utility model relates to a lighting lamp that can be rotatably fixed to a cylindrical bracket with a support plate. It includes a lamp holder 1. A light source assembly 2 is arranged at the bottom of the lamp holder 1. The interior of the lamp holder 1 is hollow, and a control circuit board 3, a power supply 4, and a switch 5 are sequentially arranged. The light source assembly 2, the power supply 4, and the switch 5 are all electrically connected to the control circuit board 3. The control circuit board 3 has a chip. The user inputs a control instruction through the switch 5. After the chip receives the control instruction, it controls the working state of the light source assembly 2. The power supply 4 supplies power to the chip and the light source assembly 2;

[0040] As Figures 2 to 4As shown, a docking groove 102a is provided on the outer wall of the lamp holder 1, and the docking groove 102a is arranged along the axial direction of the base. The docking groove 102a is connected with the bottom of the lamp holder 1, and the other end is closed. Foreign objects can enter the interior through one end of the docking groove 102a that is connected with the top of the lamp holder 1, and the movement stroke is limited by the other end to keep it in the docking groove 102a. The docking groove 102a has a baffle 102b, which is located in the middle of the docking groove 102a, so as to be able to separate the docking groove 102a into an upper groove body and a lower groove body. The left side of the baffle 102b is formed with a through opening 102c, that is, the length of the baffle 102b is less than the width of the docking groove 102a, thereby forming the through opening 102c. It should be mentioned that the position of the through opening 102c is determined according to the placement state of the entire lighting fixture. Here, the state of the light source assembly 2 facing downward is taken as a reference. The through opening 102c connects the upper and lower grooves of the docking groove 102a located above and below the baffle 102b. When the lighting fixture of the utility model is connected to the cylindrical bracket 10 with the light source assembly 2 facing downward, in order to obtain the support plate 1001, align the support plate 1001 with the docking groove 102a, and move the two relative to each other, so that the support plate 1001 can be buckled into the lower groove body of the docking groove 102a. At this time, the position of the support plate 1001 is generally directly opposite to the through-port 102c, or opposite to the baffle 102b. In the case of being opposite to the through-port 102c, it can be further relatively moved through the through-port 102c to enter the upper groove body. If it is opposite to the baffle 102b and is blocked by the baffle 102b, the lamp holder 1 must be rotated toward the through-port 102c until the support plate 1001 is opposite to the through opening 102c, and then enters the upper groove body, and finally the support plate 1001 is embedded above the baffle 102b by rotating the lamp holder 1, thereby limiting the upward movement of the baffle 102b and the entire lamp holder 1, and avoiding the lamp holder 1 to be separated from the cylindrical bracket 10 when subjected to an unexpected force along the axial direction of the cylindrical bracket 10, thereby preventing it from falling. At the same time, it can also limit the rotation of the lamp holder 1 away from the through opening 102c, reducing the possibility of its deflection under the action of unexpected force, thereby more stably maintaining the lighting direction of the light source assembly 2, and significantly improving the lighting effect and user experience.

[0041] like Figures 2 to 4 As shown, it also includes a magnet 6, and there are multiple magnets 6. A fixing groove 101a is formed at the bottom of the lamp holder 1. The fixing grooves 101a correspond to the magnets 6 one by one and are arranged around the center of the lamp holder 1. The magnet 6 is embedded in the corresponding fixing groove 101a, and is fixed to the fixing groove 101a by a simple plug-in method, which facilitates the installation of the magnet 6. When the lighting lamp of the utility model is connected to the cylindrical bracket 10, the magnet 6 can be adsorbed and fixed to the cylindrical bracket 10 made of metal, so that the lamp holder 1 and the cylindrical bracket 10 remain relatively fixed, thereby better improving the stability of the connection.

[0042] Further, the width of the docking groove 102a is greater than the width of the support plate 1001 of the cylindrical bracket 10, so that the support plate 1001 can be embedded into the docking groove 102a, providing necessary space for the support plate 1001 to move horizontally in the docking groove 102a, and the width of the through port 102c is greater than or equal to the width of the support plate 1001, accordingly enabling the support plate 1001 to finally enter the upper groove body above the baffle 102b through the through port 102c.

[0043] Further, the number of the docking grooves 102a is four, ensuring that the number of the docking grooves 102a is equal to the number of the support plates 1001 on the cylindrical bracket 10. When connected to the cylindrical bracket 10, each docking groove 102a is matched with a corresponding support plate 1001, thereby increasing the fixing points after connection and enabling the lighting device of the present utility model to be stably supported.

[0044] As Figure 6 and Figure 7 shown, a light source installation groove 102d is formed at the bottom of the lamp holder 1, and the light source installation groove 102d communicates with the inside of the lamp holder 1, thus facilitating wire connection. The light source assembly 2 is detachably connected to the light source installation groove 102d, and the wire of the light source assembly 2 passes through to the inside of the lamp holder 1 and is electrically connected to the control circuit board 3. The light source assembly 2 is configured to be detachable, facilitating the replacement of a new light source assembly 2 when its lifespan expires, without the need to replace the entire lighting device, thereby saving the usage cost and preventing the intact parts of the lighting device from being discarded, enabling reasonable utilization still.

[0045] As Figure 6 shown, the light source assembly 2 is a flat panel lamp assembly 2A. The flat panel lamp assembly 2A includes a flat panel lamp shade 201 and a lamp board 202. A plurality of LED lamp beads are provided on the lamp board 202. The lamp board 202 is placed in the light source installation groove 102d, thus forming a detachable connection relationship with the light source installation groove 102d. At the same time, the lamp board 202 is electrically connected to the control circuit board 3, and the control circuit board 3 controls the lighting and extinguishing of the lamp beads. The flat panel lamp shade 201 covers the lamp board 202 and is embedded in the light source installation groove 102d, forming a detachable connection with the light source installation groove 102d. It can be removed by controlling the movement of the flat panel lamp shade 201 in the direction away from the light source installation groove 102d. The above settings enable both the lamp board 202 and the flat panel lamp shade 201 to be conveniently disassembled or installed, improving the labor-saving feeling and efficiency of replacing the light source assembly 2. The light source assembly 2 composed of the flat panel lamp shade 201 and the lamp board 202 belongs to the flat panel lamp assembly 2A. The light-emitting surface of the flat panel light source is a plane, thus enabling the light beam to be concentrated and projected in the same direction, thereby reducing the problem of uneven brightness during lighting.

[0046] As Figure 7As shown, a first card slot 102e is formed at the top of the light source mounting groove 102d. The flat lamp shade 201 is fixed by being clamped to the first card slot 102e at the top. The bottom of the flat lamp shade 201 is fixed by the first card slot 102e, and together with the light source mounting groove 102d, it restricts the movement of the flat lamp shade 201, enabling it to be stably held in the light source mounting groove 102d after installation.

[0047] As Figure 5 and Figure 11 shown, the switch 5 is a touch switch 501. Compared with a mechanical switch, the touch switch 501 can be hidden inside the lighting lamp, enabling the overall lighting lamp to have a neater appearance and making the lighting lamp more suitable for use in humid or dusty environments.

[0048] As Figure 5 and Figure 11 shown, it further includes a solar panel 7. The solar panel 7 is electrically connected to the control circuit board 3. The solar panel 7 is installed on the top of the lamp base 1, facilitating the reception of solar energy when connected to the cylindrical bracket 10. The power supply 4 is a storage battery. The solar panel converts solar energy into electrical energy and stores it in the storage battery to charge the storage battery, making the use of the lighting lamp of the present utility model more environmentally friendly. At the same time, in occasions with dim light such as rainy and cloudy days, normal use can also be ensured. Moreover, the above settings also endow the lighting lamp of the present utility model with a portable function, facilitating users to use it outdoors without a power supply wire connection.

[0049] As Figure 2 and Figure 11 shown, it further includes a charging interface 8. The charging interface 8 is electrically connected to the control circuit board 3. The charging interface 8 is fixed on the outer wall of the lamp base 1 and is closed by a dust-proof cover 9. The charging interface 8 is specifically a type- interface. By connecting a data cable to the charging interface 8, a mobile device can be charged. Furthermore, the lighting lamp of the present utility model also functions as a mobile power supply 4, better meeting the charging needs of users when using outdoors. The dust-proof cover 9 can prevent dust, rain, snow, and other impurities from entering the charging interface 8 and causing poor contact when there is no need to charge a mobile device.

[0050] As Figure 12As shown in the figure, the lamp socket 1 includes a base 101 and a lower cover 102 which are oppositely arranged up and down. A docking groove 102a is formed on the outer side wall of the lower cover 102, and a corresponding baffle 102b is also located on the lower cover 102. The top of the docking groove 102a is closed by the base 101, so that the docking groove 102a only forms an opening at the bottom. When connecting, a step position is formed between the mating positions of the base 101 and the lower cover 102. The magnet 6 is located on the step position, and can form a step fit with the top of the cylindrical bracket 10 when connecting with the cylindrical bracket 10 through the step position. A limiting card strip 101b is formed at the bottom of the base 101. The shape of the limiting card strip 101b is the same as the shape of the top of the lower cover 102, so that it can be inserted into the lower cover 102 and form a snap connection with the lower cover 102 to realize fixation based on the lower cover 102. At the same time, an insertion post 101c is formed on the bottom of the base 101, and an insertion tube 102g which is in plug-in fit with the insertion post 101c is formed on the lower cover 102. The number of the insertion posts 101c and the corresponding insertion tubes 102g is multiple groups, so as to realize the stable connection between the two by increasing the number of fixing points.

[0051] Embodiment 2:

[0052] As Figures 7 to 10 shown in the figure, in this embodiment, the light source assembly 2 is a downlight assembly 2B. Specifically, the downlight assembly 2B is composed of a lamp holder 203, a lamp strip 204 and a cylindrical lampshade 205. One end of the lamp holder 203 is detachably fixed in the light source installation groove 102d through a threaded fastener. The lamp holder 203 is used as a skeleton to support the lamp strip 204, and it is made of aluminum profile. The other end of the lamp holder 203 extends into the external space. A slideway 203a is formed on the lamp holder 203 along the length direction. The lamp strip 204 is slidably fitted in the slideway 203a. When disassembling and assembling, the lamp strip 204 can be inserted from the end of the slideway 203a and slide along the slideway 203a to complete. In this embodiment, the number of the slideways 203a is at least one, so that multiple groups of lamp strips 204 can be installed at the same time, and then the lighting range can be expanded during lighting, and the lighting effect is more uniform. The cylindrical lampshade 205 covers the lamp holder 203, and the top is embedded in the light source installation groove 102d, so as to form a detachable connection with the light source installation groove 102d. In this embodiment, the lamp holder 203 is connected to the light source installation groove 102d by a threaded fastener, the cylindrical lampshade 205 and the light source installation groove 102d are detachably connected by an embedded method, and the lamp strip 204 and the lamp holder 203 are also detachably connected by a sliding fit, so that the user can conveniently complete the disassembly and assembly, realize the rapid replacement of the light source assembly 2 of the same panel lamp assembly 2A, and at the same time enable the light source assembly 2 of the downlight assembly 2B to project the light beam evenly outward by using the lamp strips 204 arranged in different orientations to realize large-range lighting.

[0053] As Figure 7As shown, a second card slot 102f is formed at the top of the light source installation slot 102d. The cylindrical lamp shade 205 is fixed by being snap-fitted to the second card slot 102f at the top. The function of the second card slot 102f is the same as that of the first card slot 102e. The bottom of the cylindrical lamp shade 205 is fixed through the second card slot 102f, and together with the light source installation slot 102d, the movement of the cylindrical lamp shade 205 is restricted, so that it can be stably held in the light source installation slot 102d after installation.

[0054] Refer to Figures 1 to 12 Combined with Embodiment 1 and Embodiment 2, when the lighting lamp of the present utility model is used in cooperation with the cylindrical bracket 10 with the light source assembly 2 facing downward, it is necessary to obtain the support of the support plate 1001 of the cylindrical bracket 10. First, align the support plate 1001 with the docking slot 102a one by one, and make them move relative to each other, so that the support plate 1001 is buckled into the lower slot body of the corresponding docking slot 102a. If the support plate 1001 is located at a position opposite to the through port 102c at this time, it can be further moved relative to enter the upper slot body of the docking slot 102a through the through port 102c. If it is opposite to the baffle 102b, it must first rotate the lamp holder 1 in the direction of the through port 102c until the support plate 1001 is opposite to the through port 102c, and then enter the upper slot body. Finally, by rotating the lamp holder 1, the support plate 1001 is embedded above the baffle 102b. By restricting the upward movement of the baffle 102b and the entire lamp holder 1 through the support plate 1001, the rotation of the lamp holder 1 toward the side away from the through port 102c can also be restricted, reducing the possibility of deflection under the action of accidental force. At the same time, the magnet 6 is synchronously adsorbed on the upper edge of the cylindrical bracket 10, further strengthening the stability of the connection. In addition, the type of the light source assembly 2 can also be replaced according to the user's usage requirements. When the light source assembly 2 connected to the lamp holder 1 is the lamp board 202 and the flat lamp shade 201, the flat lamp shade 201 can be first removed from the light source installation slot 102d, and then the lamp board 202 can be taken out and replaced with the light source assembly 2 of the downlight assembly 2B. If the downlight assembly 2B needs to be replaced, first remove the cylindrical lamp shade 205 from the light source installation slot 102d, and then remove the threaded fasteners fixing the lamp holder 203 to remove the lamp holder 203 together with the lamp strip 204. When the lamp strip 204 is removed, it only needs to move along the slideway 203a on the lamp holder 203.

[0055] The above embodiments and descriptions in the specification only illustrate the principles and the best embodiments of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
