Description

Technical Field

[0001] This utility model relates to the field of LED light source light technology, and in particular to an LED light source light parallelism adjustment device. Background Technology

[0002] LED light sources, or light-emitting diodes, have advantages such as small size, long lifespan, and high efficiency. They can be used continuously for up to 100,000 hours. LED light sources are becoming mainstream in the lighting field. As solid-state light emitters, LEDs are shock-resistant, impact-resistant, and not easily broken. Waste materials are recyclable and pollution-free. Their small size allows for flexible combination, making them easy to develop into lightweight, thin, and compact lighting products. They are also easy to install and maintain. LED light sources are a common lighting method for machine vision line scanning systems.

[0003] To achieve sufficient illumination intensity and uniformity, some existing LED light sources employ a close-packed array approach, relying on the overlap between multiple LED beads to achieve uniformity and sufficient intensity. However, this method results in a certain divergence angle of the LED particles, leading to light from multiple directions in both the x and y directions. In certain scenarios of machine vision applications, near-parallel light emission is required, and this type of light source is difficult to meet the usage requirements. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of some existing LED light sources, which adopt a dense array to obtain sufficient illumination intensity and uniformity, relying on the overlap between multiple LED beads to achieve uniformity and sufficient intensity. However, in this way, the LED particles have a certain divergence angle, resulting in light from multiple directions in both the x and y directions. In some scenarios of machine vision applications, it is necessary to emit approximately parallel light, and this type of light source is difficult to meet the usage requirements. Therefore, this invention provides an LED light source light parallelism adjustment device.

[0005] The purpose of this utility model is achieved through the following technical solution: an LED light source parallelism adjustment device, including an LED light source board, multiple sets of LED beads are arranged on the LED light source board, a reflector corresponding to the LED beads is installed on the LED light source board, the LED beads are arranged in the middle of the inner bottom wall of the reflector, a conical reflector front end is installed on the upper part of the reflector, the cross-section of the reflector front end is trapezoidal, the inner walls of the reflector and the reflector front end are both provided with a mirror coating, and a light-transmitting hole is opened at the top of the reflector front end. By setting the reflector and the reflector front end in cooperation, light crosstalk between connected LED beads can be blocked, and light rays exceeding the angle can be reflected and recovered, reducing the loss of light energy, so that the light emitted through the light-transmitting hole achieves a collimation effect, thereby making the light emitted by multiple sets of LED beads on the LED light source board approximately parallel light, meeting the actual use requirements.

[0006] A further technical solution is to arrange multiple sets of LED beads in a staggered array, and the reflector is cylindrical or honeycomb-shaped. By setting multiple sets of LED beads and the reflector in a staggered array, the uniformity and sufficient intensity of the light emitted by the LED light source board can be ensured, thereby improving the performance.

[0007] A further technical solution is to have the cone angle of the reflector front end be 45°.

[0008] A further technical solution is to install a copper substrate on the bottom surface of the LED light source board, which is mounted on an aluminum substrate. The copper substrate can quickly conduct the heat generated by the LED light source board to the aluminum substrate, and dissipate heat through the aluminum substrate. This can reduce the accumulation of heat on the LED light source board and effectively extend the lifespan of the LED light source board and LED chips.

[0009] A further technical solution is to install a cooling fan on the bottom surface of the aluminum substrate. By setting up the cooling fan, the heat dissipation effect of the equipment is further improved, and the LED beads on the LED light source board are prevented from overheating and being damaged.

[0010] This invention has the following advantages: By combining a reflector and a reflective front end, it can block crosstalk between connected LED beads and reflect and recover light from over-angle beams, reducing light energy loss and collimating the light emitted through the light-transmitting hole. This results in the light emitted from multiple LED beads on the LED light source board being approximately parallel, meeting practical application requirements. The staggered array of multiple LED beads and reflectors ensures the uniformity and sufficient intensity of the light emitted from the LED light source board, improving performance. The copper substrate quickly conducts heat generated by the LED light source board to the aluminum substrate for heat dissipation, reducing heat accumulation on the LED light source board and effectively extending the lifespan of both the LED light source board and the LED beads.
