Description

Technical Field

[0001] The utility model relates to the technical field of supplementary lights, in particular to a supplementary light with adjustable color temperature and brightness. Background Technique

[0002] A supplementary light is a kind of lamp used to compensate for the lack of illumination of some equipment or plants. Conventional supplementary lights adopt a two-color temperature design, that is, they include LED lamp beads with two color temperatures of warm white and cold white, and a controller is set inside the supplementary light. Through pulse width modulation technology, the current or voltage of the LED lamp beads is adjusted to achieve the brightness adjustment of the LED, and then the color temperature is adjusted by the brightness ratio of the warm white and cold white LED lamp beads.

[0003] Since the supplementary light adjusts the color temperature and brightness by changing the current or voltage, the heat generation of the supplementary light also changes with the change of the current and voltage. The action of high current and high voltage will cause the temperature of the supplementary light itself to be too high, and it is difficult to dissipate heat through a single ventilation hole in a short time, resulting in a greatly increased probability of damage to the internal circuits and components of the supplementary light. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Refer to Figures 1-5 , an auxiliary light that can adjust color temperature and brightness, including a housing 1. The housing 1 is a shell with an opening on one side. A lamp shade 2 is installed on the side of the opening of the housing 1, and a plurality of LED lamp beads are arranged in the housing 1. A controller is also arranged in the housing 1. The controller is connected to the LED lamp beads through a wire. An adjustment knob 4 is also arranged on the housing 1. The adjustment knob 4 is connected to the controller through a wire, so as to adjust the current and voltage of the LED lamp beads, thereby adjusting the color temperature and brightness of the LED lamp beads;

[0027] As Figure 1 and Figure 3As shown in the figure, on one side of the lamp housing 2 away from the casing 1, a number of vent holes 5 arranged at intervals are provided, and a support frame 3 is installed at the bottom of the casing 1. An installation frame 18 is provided on the support frame 3. The top of the installation frame 18 is arranged opposite to the bottom of the casing 1 to increase the contact surface between the support frame 3 and the casing 1 and better support the casing 1. The support frame 3 is fixed to the casing 1 through fasteners. In actual use, the fasteners are bolts, so that the casing 1 can be detachably installed on the support frame 3. An adjustment bracket is installed at the bottom of the support frame 3 to adjust the irradiation angle of the supplementary light and the set height of the supplementary light.

[0028] Among them, as Figure 1 and Figure 2 shown, the adjustment bracket includes a fixing plate 22. The fixing plate 22 is arranged below the support frame 3. A rotating shaft 19 is provided above the fixing plate 22. The end of the rotating shaft 19 is rotatably installed with a first fixing seat 20. The first fixing seat 20 is fixed to the support frame 3. A second fixing seat 21 is also installed at the end of the rotating shaft 19. The second fixing seat 21 is fixed to the fixing plate 22, so that the casing 1 can rotate on the fixing plate 22, so that the casing 1 can be turned up and down on the fixing plate 22 to adjust the irradiation angle of the supplementary light. A locking mechanism is arranged on the side of the second fixing seat 21. The locking mechanism includes a first hand-tightening bolt 23. The first hand-tightening bolt 23 penetrates through the second fixing seat 21, and the first hand-tightening bolt 23 is threadedly connected to the second fixing seat 21. The end of the first hand-tightening bolt 23 is connected with a rubber block 24 corresponding to the outside of the first fixing seat 20. After the casing 1 is rotated to a suitable angle, the first hand-tightening bolt 23 can be screwed to press the rubber block 24 against the first fixing seat 20, so as to fasten the rotation of the casing 1, thereby ensuring the stability of the casing 1 after rotation.

[0029] A support rod 25 is vertically installed at the bottom of the fixing plate 22. The bottom of the support rod 25 is placed inside the support tube 26. A support base 27 is installed at the bottom of the support tube 26. A second hand-tightening bolt 17 is threadedly connected to the side of the top of the support tube 26. The end of the second hand-tightening bolt 17 corresponds to the side wall of the support rod 25. By the telescoping of the support rod 25 in the support tube 26, the height of the casing 1 can be adjusted and fastened by the second hand-tightening bolt 17, so as to adjust the set height of the supplementary light.

[0030] Furthermore, to ensure the support strength of the support rod 25 for the fixing plate 22, a number of reinforcing plates arranged at intervals are installed on the side of the top of the support rod 25. The reinforcing plates are arranged along the radial direction of the support rod 25, and the top of the reinforcing plates is fixed to the fixing plate 22.

[0031] As Figure 3As shown in the figure, on one side of the support frame 3 close to the ventilation opening 5, a support plate 6 is vertically installed. A slot 7 is formed in the support plate 6. A frame 8 is installed along the inner wall of the slot 7. And a plurality of heat conduction plates 9 are arranged in the slot 7. The heat conduction plates 9 correspond to the ventilation openings 5 one by one. The heat conduction plates 9 are fixed by a fixing frame 10. And a plurality of fans 11 arranged at intervals are provided above the heat conduction plates 9. The fans 11 are fixed to the top of the frame 8 through a connecting frame 12. Under the operation of the fans 11, air can flow upward from below the heat conduction plates 9. In this way, air can continuously flow on the surface of the heat conduction plates 9, thereby accelerating the heat dissipation of the heat conduction plates 9.

[0032] As Figure 3 and Figure 5 shown in the figure, a connecting plate 13 is provided below the heat conduction plate 9. The connecting plate 13 is fixed to the fixing frame 10. And a screw rod 14 is threadedly connected to the connecting plate 13. One end of the screw rod 14 is rotatably installed on the support plate 6. And a handle 15 is installed at the other end of the screw rod 14. After the machine shell 1 is fixed on the support frame 3, the handle 15 can be held and rotated to move the heat conduction plate 9 towards the machine shell 1. In this way, the heat conduction plate 9 can extend into the ventilation opening 5, that is, one end of the heat conduction plate 9 is placed inside the machine shell 1. The heat accumulated in the machine shell 1 can be transferred outward along the heat conduction plate 9, thereby accelerating the outward heat dissipation of the inside of the machine shell 1.

[0033] Furthermore, at least one guide shaft 16 is arranged in parallel around the screw rod 14. One end of the guide shaft 16 is fixed to the support plate 6. And the other end of the guide shaft 16 slidably penetrates the connecting plate 13, which not only provides support for the connecting plate 13 and the heat conduction plate 9 thereon, but also provides a guiding effect for the movement of the heat conduction plate 9, so that the heat conduction plate 9 can move into the ventilation opening 5 more stably.

[0034] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
