[0027] Example

[0028] like Figure 1-4As shown, this embodiment provides a light source for detection and camera burning, including a bottom frame 3, the bottom frame 3 is an integrally formed aluminum bottom frame 3, the integrally formed structure has no connection gaps and strong thermal conductivity, the inner sides of the bottom frame 3 are respectively attached with substrates 2, the substrate 2 is fixedly connected with a first lamp bead 101 and a second lamp bead 102 in sequence from bottom to top, the first lamp bead 101 and the second lamp bead 102 are LED lamp beads, wherein the first lamp bead 101 is TL84 light, and the second lamp bead 102 is 2856K light and 5000K light, the substrate 2 is a copper substrate 2, the copper substrate 2 has a high thermal conductivity, and provides heat dissipation for the LED lamp beads, the middle part of the bottom frame 3 is embedded with a first light guide plate 14 and a second light guide plate 15, wherein the position of the first light guide plate 14 corresponds to the first lamp bead 101, and the position of the second light guide plate 15 corresponds to the second lamp bead 102, and the top cover of the bottom frame 3 is provided with a top cover plate 8.

[0029] The structures of the first light guide plate 14 and the second light guide plate 15 are the same. A plurality of engraving points are provided on the surface of the first light guide plate 14 and the second light guide plate 15. The density of the engraving points located around the first light guide plate 14 and the second light guide plate 15 gradually increases toward the middle. The engraving points are designed on the surface of the first light guide plate 14 and the second light guide plate 15 so that the light emitted by the LED lamp beads will diffuse and be guided upward after passing through the first light guide plate 14 or the second light guide plate 15. In addition, since the lamp beads are close to the surroundings of the light guide plate, the surroundings are brighter and the middle is darker. In order to adjust the light emission of the entire light-emitting surface to be more uniform, the density of the engraving points located around the first light guide plate 14 and the second light guide plate 15 gradually increases toward the middle, so that more light is guided out from the middle to make up for the dark area in the middle.

[0030] Furthermore, the first lamp beads 101 have three rows, the second lamp beads 102 have two rows, the thickness of the first light guide plate 14 is 10 mm, and the thickness of the second light guide plate 15 is 8 mm.

[0031] It should be noted that the first lamp bead 101 is an LED lamp bead that emits a TL84 light source. The TL84 light source on the market is realized by a fluorescent lamp, but the fluorescent lamp is large in size, high in power consumption, and decays quickly, while the LED lamp bead is small in size, low in power consumption, and low in decay. However, with current technology, the TL84 light source emitted by the LED lamp bead is mixed with purple light compared with the fluorescent lamp. Therefore, the first light guide plate 14 is made of a 10mm thick filter material with the ability to suppress the purple light band, so that the light emitted by the first lamp beads 101 located in the three rows below the substrate 2 is filtered by the first light guide plate 14 and then emitted. After filtering out the purple light, it can be very close to the TL84 light source emitted by the fluorescent lamp, thereby replacing the fluorescent lamp and making up for the shortcomings of the fluorescent lamp; the second lamp beads 102 are located in the two rows above the substrate 2, and the light emitted is 2856K light and 5000K light, and there is no need to filter stray light. Therefore, we use a 8mm thick second light guide plate 15 made of a full-band transparent material, which only has a light guiding function and will not affect the spectrum. The overall structure is cleverly designed, integrating TL84 (4000K) light, 2856K light and 5000K light into one light source.

[0032] In one embodiment, a diffusion plate is embedded in the interior of the bottom frame 3 on the surface of the second light guide plate 15. The diffusion plate includes two first diffusion plates 16 and second diffusion plates 17 stacked on each other, the thickness of the first diffusion plate 16 is 2 mm, and the thickness of the second diffusion plate 17 is 1 mm. After the light source is diffused by the light guide plate, it continues to diffuse through the first diffusion plate 16 and the second diffusion plate 17, so that the light source is more evenly distributed.

[0033] Furthermore, a plurality of heat sinks 5 are integrally formed at the bottom of the bottom frame 3. The plurality of heat sinks 5 increase the contact area between the bottom frame 3 and the air, thereby improving the heat dissipation efficiency of the bottom frame 3.

[0034] Furthermore, a plurality of cooling fan slots 10 are provided at the bottom of the bottom frame 3, and cooling fans 18 are embedded in the cooling fan slots 10. Through the operation of the plurality of cooling fans 18, the heat dissipation efficiency is accelerated in a strong convection manner.

[0035] Furthermore, a power supply line slot 12 is provided at the bottom of the bottom frame 3, a power supply line adapter plate 11 is fixedly connected in the power supply line slot 12, a power supply line slot cover plate 13 is detachably connected to the surface of the power supply line slot 12, the power supply line adapter plate 11 is connected to the first lamp bead 101 and the second lamp bead 102 through internal wiring, the power supply line adapter plate 11 is connected to the power supply line, and an opening is provided on the side of the power supply line slot 12 to allow the power supply line to pass through. The power supply line adapter plate 11 is installed in the power supply line slot 12 and is protected by the power supply line slot cover plate 13, which can protect the power supply line from external influences and prevent malfunctions.

[0036] In one embodiment, the bottom frame 3 is provided with a plurality of locking screw through holes 6, the top cover plate 8 is provided with locking screw holes 9 at positions corresponding to the locking screw through holes 6, the locking screw through holes 6 are penetrated by locking screws 7, and the locking screws 7 are fixedly connected to the locking screw holes 9. The top cover plate 8 and the bottom frame 3 are fixed by the plurality of locking screws 7, and the structure is stable and the installation is firm.

[0037] In one embodiment, a plurality of mounting holes 4 are provided at the bottom of the bottom frame 3. The mounting holes 4 are used to mount the light source on the automation equipment.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
