[0002] In a visual detection system, a parallel light source can greatly increase the contrast between a measured object and a background, thereby reducing the requirements of the system on image processing algorithms and improving the positioning accuracy of edges. However, the current parallel light source has the following defects:

[0003] 1. A large amount of heat is generated in the operation process of the light source. The high temperature not only affects the stability of the light source, but also may cause damage to the surrounding equipment. To solve this problem, the light source equipment in the prior art usually uses a fan or a heat sink for cooling treatment. However, such a method has high energy consumption and limited effect. Temperature change has a great influence on the performance of the light source. However, the prior art lacks effective means for real-time monitoring and adjusting the temperature of the light source.

[0004] 2. The light path design of the existing light source is relatively simple, and it is difficult to achieve accurate control of light. This results in low utilization of the light source and cannot meet the high-precision imaging requirements in some precision detection scenarios. SUMMARY

[0036] As Figures 1 to 6 , a kind of energy-saving parallel visual light source with infrared temperature measurement provided by the present application is disclosed, including connection main seat 1, cooling fan 2, light source assembly 3 and temperature sensor 4:

[0037] AsFigures 1 to 3 As shown, the connection main seat 1 in this embodiment is in the shape of L, one end of which is fixed with the heat dissipation seat 5 through screws, the other end of the connection main seat 1 is provided with the first mounting hole 11, and the temperature sensor 4 is mounted on the first mounting hole 11, so that the temperature sensor 4 is placed above the heat dissipation seat 5, and the working end of the temperature sensor 4 faces the heat dissipation seat 5, for monitoring the temperature of the heat dissipation seat 5, as shown in Figure 1 As shown, the outer edge of the heat dissipation seat 5 in this embodiment is provided with a plurality of heat dissipation fins 51, and gaps 52 are formed between the heat dissipation fins 51, which are the second air ducts, and the first heat dissipation structure 53 is arranged on the heat dissipation seat 5, and the heat dissipation fan 2 is mounted on the other end of the heat dissipation seat 5 and faces the first heat dissipation structure 53 and the second air duct, and the first heat dissipation structure 53 specifically includes the first air hole 531 arranged at the center of the heat dissipation seat 5 and the first heat conduction column 532 arranged inside the first air hole 531, the first air hole 531 penetrates the center of the heat dissipation seat 5, and one end of the first heat conduction column 532 abuts against the LED lamp holder 31, and the other end of the first heat conduction column 532 away from the LED lamp holder 31 is a tapered heat dissipation part 5321, and the tapered heat dissipation part 5321 faces the heat dissipation fan 2, as shown in Figure 3 As shown, a space is formed between the tapered heat dissipation part 5321 and the heat dissipation fan 2, and the principle of the first heat conduction column 532 is that the first heat conduction column 532 is made of copper, brass, copper alloy or other metal materials with good heat conduction performance, and the end thereof abuts against the LED lamp holder 31, so that the heat of the LED lamp holder 31 can be conducted to the tapered heat dissipation part 5321, and the tapered heat dissipation part 5321 is arranged to increase the contact area with the fan airflow, thereby achieving better heat dissipation effect.

[0038] In some embodiments, a heat dissipation gap is left between the outer circumferential surface of the first heat conduction column 532 and the inner wall of the first air hole 531, thereby forming an air flow channel surrounding the first heat conduction column 532, and further improving the heat dissipation effect of the first heat conduction column 532.

[0039] In order to further improve the heat dissipation effect of the LED lamp holder 31, as shown in Figure 4 As shown, the embodiment further includes a plurality of heat equalization columns 54, a plurality of evenly distributed heat equalization through holes 55 are arranged on the heat dissipation seat 5, one end of the heat equalization column 54 is inserted into the heat equalization through hole 55 and fixed and abuts against the heat dissipation fin 51, and the other end of the heat equalization column 54 extends outward away from the heat dissipation seat 5 to form a heat dissipation end, and the end of the heat dissipation end is used to fixedly connect the heat dissipation fan 2, so that the heat dissipation fan 2 and the heat dissipation seat 5 form a heat dissipation area 56, the heat equalization column 54 is in close contact with the heat dissipation fin 51 through the heat equalization through hole 55, can quickly transfer the heat inside the heat dissipation seat 5 to the heat dissipation area 56, and cooperate with the operation of the heat dissipation fan 2 to drive the external air flow, thereby further improving the heat dissipation efficiency.

[0040] Preferably, the heat equalizing column 54 is a copper pipe made of pure copper or copper alloy or other materials with good heat conduction performance, and is made of materials with good heat dissipation performance to effectively improve the heat conduction efficiency.

[0041] Therefore, in order to cooperate with the speed regulation function of the heat dissipation fan 2 by the temperature sensor 4, the controller (not shown in the figure) is arranged to cooperate with the operation, and the temperature of the heat dissipation seat 5 is monitored in real time by the temperature sensor 4. For example, when the device is working, the LED lamp beads 311 will emit heat with continuous irradiation, and the heat dissipation seat 5 will absorb the heat of the LED lamp beads 311 and heat up. When the temperature sensor 4 monitors the temperature of the heat dissipation seat 5, the controller compares the temperature monitored by the temperature sensor 4 with the preset temperature threshold value. For example, when the monitored temperature is 40℃, the input voltage of the heat dissipation fan 2 is 15V, and the speed of the heat dissipation fan 2 is 6100RPM at this time; when the monitored temperature is 40℃-50℃, the input voltage of the heat dissipation fan 2 is 20V, and the speed of the heat dissipation fan 2 is 7800RPM at this time; when the monitored temperature is 50℃-60℃, the input voltage of the heat dissipation fan 2 is 24V, and the speed of the heat dissipation fan 2 is 9000RPM at this time. With the increase of the power of the light source assembly 3 and the continuous working temperature, the controller compares the temperature monitored by the temperature sensor 4 with the preset threshold value to adjust the working voltage of the heat dissipation fan 2, and then controls the size of the speed. The above example is only for illustration of temperature rise. Similarly, when the temperature decreases from high temperature to low temperature, the speed of the heat dissipation fan 2 can be reduced by the controller, so as to reasonably allocate resources and reduce energy consumption.

[0042] As shown in Figures 3 to 5 The light source assembly 3 includes an LED lamp holder 31 and a sleeve 32, the sleeve 32 is provided with a first lens 36 and a second lens 38 for adjusting the light of the LED lamp holder 31, the LED lamp holder 31 is fixedly connected to one end of the heat dissipation seat 5 and abuts against the first heat conduction column 532, one end of the sleeve 32 wraps the LED lamp holder 31 connected with the heat dissipation seat 5, so that the air flow of the second air duct enters the outside of the sleeve 32, the lens group is arranged in the sleeve 32 to adjust the light of the LED lamp beads 311, and the LED lamp beads 311 are arranged on the LED lamp holder 31. In this embodiment, the sleeve 32 includes an upper ring 33 and a lower ring 34 which are buckled to each other, the upper ring 33 and the lower ring 34 are tightly connected by buckling or thread, and preferably a sealing glue is arranged to seal, so that the two are connected and sealed and firm, which can effectively prevent external dust or impurities from entering the light path channel, thereby ensuring the light efficiency and quality of the LED light source.

[0043] The first installation cavity 331 wrapping the LED lamp holder 31 is arranged in the upper ring 33, the first light path channel 332 communicating with the first installation cavity 331, and the connecting channel 333. The first compression ring 35 is arranged at the connection between the first installation cavity 331 and the first light path channel 332. The first lens 36 is clamped on the first compression ring 35. The first compression ring 35 is a hollow ring body for fixing the first lens 36. The first lens 36 is a convex lens. The second compression ring 37 is arranged between the first light path channel 332 and the connecting channel 333. The light ray through hole 371 is arranged on the second compression ring 37. In this embodiment, the light ray through hole 371 is a tapered concave hole. The included angle α between the edge line of the cross section of the light ray through hole 371 and the edge line of the second compression ring 37 is 35°-45°. The light ray through hole 371 can block the stray light with a large angle, so that the light with a suitable angle can enter the second light path channel 342 through the light ray through hole 371, thereby effectively improving the collimation and uniformity of the subsequent light beam, reducing light loss and improving the overall lighting effect. Therefore, the size of the included angle α can be adjusted according to actual use requirements, for example, it can be set to 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44° or 45°, thereby flexibly adapting to different optical design requirements. Under the premise of ensuring the quality of the light path, the lighting performance and energy efficiency of the light source assembly 3 are further optimized.

[0044] The lower ring 34 includes the second installation cavity 341 for sleeving the connecting channel 333, the second light path channel 342 communicating with the second installation cavity 341, and the third light path channel 343 communicating with the second light path channel 342. The third light path channel 343 has the light outlet 344 at the end. The second lens 38 is clamped on the light outlet 344. The second lens 38 is a double convex lens. The second lens 38 can be fixed by the third compression ring 345. In particular, the diameter D1 of the first light path channel 332, the diameter D2 of the second light path channel 342, and the diameter D3 of the third light path channel 343 satisfy D2>D3>D1 and D3>D1. Such diameter design can ensure that the light beam reduces edge reflection and light loss during transmission in each channel, while ensuring that the focusing and collimation effect of the light path reaches the best.

[0045] To ensure the accuracy and consistency of the light transmission path, the first lens 36, the light ray through hole 371 and the second lens 38 of the embodiment are on the same axis.

[0046] Figure 6As shown, the application emits light source from the LED lamp bead 311, and the LED lamp bead 311 can also adjust the output power to realize the brightness adjustment through the controller, after the LED lamp bead 311 emits light, the light is preliminarily focused through the first lens 36, then enters the first light path channel 332, and the second compression ring 37 is arranged at the end of the first light path channel 332, the second compression ring 37 screens the stray light through the light through hole 371, ensures that the light of the appropriate angle enters the next stage, then the light enters the second light path channel 342 and the third light path channel 343, the diameter of the first light path channel 332 is relatively small, so that the light is preliminarily constrained, and the diameter of the second light path channel 342 is the largest, so that the light screened through the light through hole 371 is fully unfolded, then the light is further constrained by the third light path channel 343, finally the light is finally collimated through the second lens 38, and the light is parallelly emitted, so that the high-precision lighting effect of ±0.5° collimation deviation and edge illumination decay <3% is realized, and the high-precision lighting effect is especially suitable for the fields of industrial detection, optical measurement and display system with high requirements on light beam quality

[0047] The preferred embodiments of the application have been described above, but the application is not limited to the above, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the application shall be included in the protection scope of the application.
