Description

Technical Field

[0001] This utility model relates to the field of detection light source equipment technology, and in particular to an energy-saving parallel vision light source with infrared temperature measurement. Background Technology

[0002] In visual inspection systems, parallel light sources can significantly increase the contrast between the object being measured and the background, thereby reducing the system's requirements for image processing algorithms and improving edge localization accuracy. However, parallel light sources currently have the following drawbacks:

[0003] 1. A large amount of heat is generated during the operation of the light source. Excessive temperature will not only affect the stability of the light source, but may also damage the surrounding equipment. To solve this problem, the existing light source equipment mostly uses fans or heat sinks for cooling. However, such methods are energy-intensive and have limited effect. Temperature changes have a great impact on the performance of the light source, but the existing technology lacks an effective means to monitor and adjust the temperature of the light source in real time.

[0004] 2. The existing light source has a relatively simple optical path design, which makes it difficult to achieve precise control of light, resulting in low light source utilization and inability to meet the high-precision imaging requirements in some precision detection scenarios. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide an energy-saving parallel vision light source with infrared temperature measurement. This invention can automatically adjust the cooling fan speed according to the temperature. Combined with a three-layer heat dissipation architecture, it improves heat dissipation efficiency and reduces energy consumption. At the same time, this invention uses a combined lens array to effectively correct collimation deviation, improve the precise control of the light source, and increase its utilization rate.

[0006] To achieve the above objectives, this utility model provides an energy-saving parallel vision light source with infrared thermometry, comprising:

[0007] A connecting main seat is provided, and a heat sink is connected to the connecting main seat. A first heat dissipation structure is provided on the heat sink. Several heat dissipation fins are arranged around the outer periphery of the heat sink, and a second air duct is formed between the heat dissipation fins.

[0008] A cooling fan is installed at the other end of the heat sink and faces the first heat dissipation structure and the second air duct.

[0009] The light source assembly includes an LED lamp holder and a sleeve. The LED lamp holder is fixed to one end of the heat sink and abuts against the first heat sink structure. One end of the sleeve wraps around the LED lamp holder and connects to the heat sink, allowing the airflow of the second air duct to enter the outer periphery of the sleeve. The sleeve is provided with a first lens and a second lens to adjust the light of the LED lamp holder. LED beads are provided on the LED lamp holder.

[0010] A temperature sensor is fixed to the main connector and positioned above the heat sink to monitor its temperature.

[0011] Furthermore, the first heat dissipation structure includes a first ventilation hole and a first heat-conducting column. The first ventilation hole penetrates the center of the heat sink, and the first heat-conducting column is disposed inside the first ventilation hole, with one end of the first heat-conducting column abutting against the LED lamp holder. By setting the first ventilation hole and the heat-conducting column, the first ventilation hole penetrates the heat sink and forms a ventilation channel, which can effectively improve the heat conduction efficiency inside the heat sink. The heat-conducting column is inserted into the first ventilation hole and abuts against the LED lamp holder, which can quickly transfer the heat of the LED lamp holder to the heat dissipation fins and exhaust it from the first ventilation hole, thereby achieving a highly efficient heat dissipation effect and reducing overall energy consumption.

[0012] Furthermore, the end of the first heat-conducting column furthest from the LED lamp holder is a tapered heat dissipation section, which faces the cooling fan. The tapered heat dissipation section at the end of the first heat-conducting column facilitates rapid heat dissipation and improves heat dissipation efficiency. In addition, the tapered structure guides airflow, enhancing the airflow speed of the first ventilation hole, thereby further improving the heat dissipation effect.

[0013] Furthermore, the system includes several heat-spreading columns. Multiple evenly distributed heat-spreading holes are provided on the heat sink. One end of each heat-spreading column is inserted into and fixed within one of the heat-spreading holes, abutting against the heat dissipation fins. The other end of each heat-spreading column extends outward from the heat sink to form a heat dissipation end. This heat dissipation end is used to fix a cooling fan, creating a heat dissipation area between the cooling fan and the heat sink. The heat-spreading columns, through the heat-spreading holes, are in close contact with the heat dissipation fins, enabling rapid heat transfer from inside the heat sink to the heat dissipation area. Combined with the operation of the cooling fan driving external airflow, this further improves heat dissipation efficiency.

[0014] Furthermore, the heat dissipation column is a copper tube made of pure copper, copper alloy, or other materials with good thermal conductivity. Using materials with excellent heat dissipation properties effectively improves heat transfer efficiency.

[0015] Furthermore, the sleeve includes an upper and lower circumference rings that interlock with each other. The upper circumference ring contains a first mounting cavity that encloses the LED lamp holder, a first optical path channel communicating with the first mounting cavity, and a connecting channel. A first pressure ring is provided at the connection between the first mounting cavity and the first optical path channel, and the first lens is snapped onto the first pressure ring. A second pressure ring is provided between the first optical path channel and the connecting channel, and a light-passing hole is provided on the second pressure ring. The lower circumference ring includes a second mounting cavity for engaging with the connecting channel, a second optical path channel communicating with the second mounting cavity, and a third optical path channel communicating with the second optical path channel. The end of the third optical path channel is a light-emitting port, and the second lens is snapped onto the light-emitting port. The upper and lower circumference rings are tightly connected by interlocking or threading, preferably sealed with sealant, ensuring a secure and sealed connection. This effectively prevents external dust or impurities from entering the optical path channel, thereby guaranteeing the light output efficiency and quality of the LED light source. A first retaining ring is installed between the first optical path channel and the connecting channel to fix the first lens and prevent lens displacement or loosening from affecting optical performance. A second retaining ring is installed between the first optical path channel and the second optical path channel. The light-passing hole on the second retaining ring can filter the light beam focused by the first lens, allowing the qualified light beam to pass through. Then, in conjunction with the second lens, it is collimated to effectively enhance and collimate the optical path, ultimately obtaining parallel light.

[0016] Furthermore, the first lens, the light aperture, and the second lens are all aligned on the same axis. This ensures the precision and consistency of the light transmission path, thereby achieving higher optical efficiency and beam control accuracy.

[0017] Furthermore, the first lens is a convex lens, and the second lens is a biconvex lens. Setting the first lens as a convex lens can initially focus the light emitted by the LED beads, and in conjunction with the light aperture to filter stray light with a large angle, it can effectively improve the concentration and utilization of the beam. The biconvex structure of the second lens further collimates the filtered light, making the output beam more uniform and parallel, thereby significantly improving the lighting effect and light propagation efficiency.

[0018] Furthermore, the light-transmitting aperture is a conical concave aperture, and the angle between the edge of the light-transmitting aperture cross-section and the edge of the second pressure ring is 35° to 45°. The conical concave aperture effectively blocks stray light with a large scattering angle. After collimation with the second lens, a relatively parallel and concentrated beam can be obtained. At the same time, the design of this conical concave aperture can also avoid multiple reflections of light at the edge of the aperture, which would affect the subsequent collimation effect of the beam.

[0019] Furthermore, the diameter of the first optical path channel is D1, the diameter of the second optical path channel is D2, and the diameter of the third optical path channel is D3, with D2 > D3 > D1 and D3 > D1. This diameter design ensures that edge reflection and light loss are reduced during the transmission of the light beam in each channel, while ensuring that the focusing and collimation effects of the optical path are optimal.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] This invention forms a first heat dissipation channel for the LED lamp holder by forming a first through hole on the heat sink and cooperating with a first heat-conducting column. A second heat dissipation channel for the LED lamp holder and sleeve is formed between the heat dissipation fins. A heat-spreading column is set between the heat dissipation fins and the heat dissipation fan to connect and form a heat dissipation area, which further improves the heat dissipation efficiency and ensures the stable operation of the LED light source for a long time.

[0022] This invention also includes a temperature sensor for real-time detection of the heat sink temperature. The speed of the cooling fan can be adjusted according to the temperature to achieve an intelligent energy-saving mode. The energy saving rate is 60% to 80% higher than that of traditional light sources. Through intelligent temperature monitoring, the LED operates in the optimal performance range, and the expected service life is extended to 60,000 hours.

[0023] This invention, through the combination of a first lens, a light-passing hole, and a second lens, enables a novel optical path adjustment structure that first focuses, filters out stray light, and then collimates the light emitted from LED beads, achieving a collimation deviation of ±0.5° and an edge illuminance attenuation of <3%, compared to >15% for conventional parallel light sources.

[0033] The technology of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0034] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0035] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0036] like Figures 1 to 6This invention discloses an energy-saving parallel vision light source with infrared temperature measurement, comprising a connecting base 1, a cooling fan 2, a light source assembly 3, and a temperature sensor 4.

[0037] like Figures 1 to 3 As shown, in this embodiment, the main connector 1 is L-shaped, with a heat sink 5 fixed to one end by screws. The other end of the main connector 1 has a first mounting hole 11, on which the temperature sensor 4 is mounted. The temperature sensor 4 is positioned above the heat sink 5, with its working end facing the heat sink 5, for monitoring the temperature of the heat sink 5. Figure 1 As shown, in this embodiment, a plurality of heat dissipation fins 51 are arranged around the outer edge of the heat sink 5, and gaps 52 are formed between the heat dissipation fins 51. These gaps 52 constitute the second air duct. A first heat dissipation structure 53 is provided on the heat sink 5, and a cooling fan 2 is installed at the other end of the heat sink 5, facing the first heat dissipation structure 53 and the second air duct. Specifically, the first heat dissipation structure 53 includes a first ventilation hole 531 and a first heat-conducting column 532 located at the center of the heat sink 5. The first ventilation hole 531 penetrates the center of the heat sink 5, and the first heat-conducting column 532 is disposed inside the first ventilation hole 531. One end of the first heat-conducting column 532 abuts against the LED lamp holder 31, and the other end of the first heat-conducting column 532 away from the LED lamp holder 31 is a conical heat dissipation part 5321. This conical heat dissipation part 5321 faces the cooling fan 2. Figure 3 As shown, a certain space is formed between the conical heat dissipation part 5321 and the cooling fan 2. The principle of the first heat-conducting column 532 is that the first heat-conducting column 532 is made of copper, brass, copper alloy or other metal materials with good thermal conductivity. Through its end abutting against the LED lamp holder 31, the heat of the LED lamp holder 31 can be conducted to the conical heat dissipation part 5321. The conical heat dissipation part 5321 is designed to increase the contact area with the fan airflow, thereby achieving a better heat dissipation effect.

[0038] In some embodiments, a heat dissipation gap is left between the outer peripheral surface of the first heat-conducting column 532 and the inner wall of the first ventilation hole 531, thereby forming a ventilation channel around the first heat-conducting column 532, further improving the heat dissipation effect of the first heat-conducting column 532.

[0039] To further improve the heat dissipation effect of LED lamp holder 31, such as Figure 4As shown, this embodiment also includes several heat-spreading columns 54. Multiple evenly distributed heat-spreading holes 55 are provided on the heat sink 5. One end of the heat-spreading column 54 is inserted into the heat-spreading hole 55 and fixed, and abuts against the heat dissipation fin 51. The other end of the heat-spreading column 54 extends outward away from the heat sink 5 to form a heat dissipation end. The end of the heat dissipation end is used to fix the cooling fan 2, so that the cooling fan 2 and the heat sink 5 form a heat dissipation area 56. The heat-spreading column 54 is in close contact with the heat dissipation fin 51 through the heat-spreading hole 55, which can quickly transfer the heat inside the heat sink 5 to the heat dissipation area 56. With the operation of the cooling fan 2, the external airflow is driven, which further improves the heat dissipation efficiency.

[0040] Preferably, the heat dissipation column 54 is a copper tube made of pure copper or copper alloy or other materials with good thermal conductivity. Using materials with good heat dissipation performance can effectively improve heat transfer efficiency.

[0041] Therefore, to coordinate with the speed control function of the cooling fan 2 by the temperature sensor 4, this utility model also includes a controller (not shown in the figure) to work in conjunction with the device. The temperature sensor 4 monitors the temperature of the heat sink 5 in real time. For example, when the device is operating, the LED beads 311 will generate heat due to continuous irradiation, and the heat sink 5 will absorb the heat from the LED beads 311 and rise in temperature. When the temperature sensor 4 monitors the temperature of the heat sink 5, the controller will compare the temperature monitored by the temperature sensor 4 with a preset temperature threshold. For example, when the monitored temperature is 40℃, the controller will set the input voltage of the cooling fan 2 to 15V, and the speed of the cooling fan 2 will be 6100RPM. At ~50℃, the controller sets the input voltage of cooling fan 2 to 20V, at which point the speed of cooling fan 2 is 7800RPM. When the monitored temperature is 50℃~60℃, the controller sets the input voltage of cooling fan 2 to 24V, at which point the speed of cooling fan 2 is 9000RPM. Thus, as the power of light source component 3 increases and the continuous operating temperature rises, the controller compares the temperature monitored by temperature sensor 4 with a preset threshold to adjust the operating voltage of cooling fan 2, thereby controlling its speed. The above example is only for illustrating the temperature rise. Similarly, when the temperature drops from high to low, the controller can reduce the speed of cooling fan 2, thereby rationally allocating resources and reducing energy consumption.

[0042] like Figures 3 to 5As shown, the aforementioned light source assembly 3 includes an LED lamp holder 31 and a sleeve 32. The sleeve 32 contains a first lens 36 and a second lens 38 to adjust the light emitted from the LED lamp holder 31. The LED lamp holder 31 is fixed to one end of the heat sink 5 and abuts against the first heat-conducting column 532. One end of the sleeve 32 wraps around the LED lamp holder 31 and connects to the heat sink 5, allowing airflow from the second air duct to enter the outside of the sleeve 32. The lens group is located inside the sleeve 32 to adjust the light emitted from the LED beads 311. LED beads 311 are mounted on the LED lamp holder 31. In this embodiment, the sleeve 32 includes an upper circumference ring 33 and a lower circumference ring 34 that interlock with each other. The upper circumference ring 33 and the lower circumference ring 34 are tightly connected by interlocking or threading, preferably sealed with sealant to ensure a tight and secure connection. This effectively prevents external dust or impurities from entering the light path, thereby ensuring the light output efficiency and quality of the LED light source.

[0043] Within the ring 33, a first mounting cavity 331 is provided to enclose the LED lamp holder 31, a first optical path channel 332 communicating with the first mounting cavity 331, and a connecting channel 333. A first retaining ring 35 is provided at the connection between the first mounting cavity 331 and the first optical path channel 332. A first lens 36 is snapped onto the first retaining ring 35. The first retaining ring 35 is a hollow ring used to fix the first lens 36. The first lens 36 is a convex lens. A second retaining ring 37 is provided between the first optical path channel 332 and the connecting channel 333. A light-passing hole 371 is provided on the second retaining ring 37. In this embodiment, the light-passing hole 371 is a conical concave hole. The edge of the cross-section of the light-passing hole 371 is perpendicular to the second retaining ring 37. The included angle α of the edge of ring 37 is 35° to 45°. The light through hole 371 can block stray light with a large angle, so that light with a suitable angle can enter the second optical path channel 342 through the light through hole 371, thereby effectively improving the collimation and uniformity of the subsequent 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 needs. For example, it can be set to 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44° or 45°, so as to flexibly adapt to different optical design requirements and further optimize the lighting performance and energy efficiency of the light source component 3 while ensuring the quality of the optical path.

[0044] The next ring 34 includes a second mounting cavity 341 for engaging with the connecting channel 333, a second optical path channel 342 communicating with the second mounting cavity 341, and a third optical path channel 343 communicating with the second optical path channel 342. At the end of the third optical path channel 343 is a light exit port 344. A second lens 38 is snapped onto the light exit port 344. The second lens 38 is a biconvex lens, and it can be fixed by a third retaining ring 345. Specifically, the diameters of the first optical path channel 332 (D1), the second optical path channel 342 (D2), and the third optical path channel 343 (D3) are: D2 > D3 > D1. This diameter design ensures that edge reflections and light loss are reduced during beam transmission in each channel, while also ensuring optimal focusing and collimation of the optical path.

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

[0046] Figure 6 As shown, this invention emits a light source from an LED bead 311. The brightness of the LED bead 311 can also be adjusted by regulating its output power via a controller. After the LED bead 311 emits light, the light is initially focused by the first lens 36 and then enters the first optical path channel 332. Simultaneously, a second pressure ring 37 is placed at the end of the first optical path channel 332. The second pressure ring 37 filters stray light through a light-passing hole 371, ensuring that light at the appropriate angle enters the next stage. The light then enters the second optical path channel 342 and the third optical path channel 343. The first optical path channel 332 has a relatively small diameter, facilitating initial constraint of the light, while the second optical path channel 342 has the largest diameter, allowing the light filtered by the light-passing hole 371 to fully expand. The third optical path channel 343 then further constrains the light, and finally, the second lens 38 performs final collimation, achieving parallel emission. This results in a high-precision lighting effect with a collimation deviation of ±0.5° and an edge illuminance attenuation of <3%, making it particularly suitable for industrial inspection, optical measurement, and display systems where high beam quality is required.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
