[0002] Different from the divergent light of traditional general lighting, some optical lighting applications require parallel collimated light, such as projection display, UV curing, photolithography, stage lighting, car lights, 3D printing and other application fields. The commonly used light sources on the market are mainly high-pressure mercury lamps, LEDs, and LDs. Among them, high-pressure mercury lamps have basically been eliminated due to low luminous efficiency and high power consumption; LDs are difficult to be widely popularized due to cost and safety regulations. LED light sources have become the irreplaceable mainstream light source in the lighting application market due to their high luminous efficiency, mature technology, extremely cost-effective, safety and environmental protection.

[0003] Commonly used collimating optical devices include reflectors and lenses. In order to achieve the collimation effect, they must be compatible with the luminous characteristics of the light source. The light intensity distribution of LED light sources generally obeys Lambert's cosine law, which makes the size of the collimating optical device much larger than the size of the light source.

[0004] Currently, most collimating optical systems adopt discrete optical component design. Their optical systems mainly include heat sinks, light sources, light channels, lenses, lens components, etc., which have different specifications, numerous parts, complex assembly, and large size. In addition, the various parts or components of their optical systems are designed and produced by different manufacturers, and finally mixed and combined by the manufacturers, resulting in seriously low optical efficiency of their collimating optical systems, and triggering a series of problems such as low light utilization, poor brightness uniformity, excessive power consumption, and large size.

[0005] Therefore, it is necessary to provide a double-layer multi-hole collimating light channel to solve the above technical problems. Summary of the Invention

[0082] Second embodiment:

[0083] See also Figure 5 、 Figure 6 and Figure 7, based on a double-layer multi-porous collimated light flux provided in the first embodiment of the present application, the second embodiment of the present application proposes another double-layer multi-porous collimated light flux. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. Specifically, the difference between the double-layer multi-porous collimated light flux provided in the second embodiment of the present application is that it includes the double-layer multi-porous collimated light flux, and the collimated light flux needs to be subjected to light detection after the double-layer multi-porous collimated light flux is produced and formed, so a double-layer multi-porous collimated light flux auxiliary detection device is required, and also includes:

[0084] A support frame 4, wherein at least two sets of slide grooves 401 are formed on the support frame 4, and a mounting platform 41 is fixedly mounted on the support frame 4;

[0085] The light detection plate 5, the bottom of which is slidably mounted on the support frame 4 via two sets of movable sliders 51 and two sets of sliding grooves 401;

[0086] The moving mechanism 6 includes a moving motor 61 and a moving wheel 62. The moving motor 61 is fixedly mounted on the light detection plate 5. The moving wheel 62 is fixedly mounted on the shaft end of the moving motor 61. The surface of the moving wheel 62 is rollingly mounted on the support frame 4.

[0087] A light source generator 7, the light source generator 7 is fixedly mounted on the mounting platform 41;

[0088] The clamping mechanism 8 is mounted on the mounting platform 41 . The collimating light transmission mechanism 100 is mounted on the clamping mechanism 8 , and the light source input end of the collimating light transmission mechanism 100 is connected to the light source output end of the light source generator 7 .

[0089] By installing the formed collimating light transmission mechanism 100 on the clamping mechanism 8, and aligning the light source input end of the collimating light transmission mechanism 100 on the light source generator 7, a movable light detection plate 5 is provided on the support frame 4, which facilitates the detection of the illumination range of the collimating light transmission mechanism 100 at different points without manual movement, and facilitates the rapid and stable adjustment of the detection points.

[0092] The moving motor 61 adopts a stepping motor. When in use, the external power supply provides the power source for driving the moving wheel 62. When the moving wheel 62 rotates, it can move stably on the support frame 4. When the moving wheel 62 moves, it is convenient to drive the light detection plate 5 to move and adjust synchronously, thereby facilitating the adjustment of the use point of the light detection plate 5.

[0093] The working principle of the double-layer multi-hole collimated light flux auxiliary detection device provided by the present invention is as follows:

[0094] When the use point of the light detection plate 5 needs to be adjusted, the moving motor 61 is started, and the moving motor 61 drives the moving wheel 62 to rotate, and the moving wheel 62 rolls stably on the support frame 4. While the moving wheel 62 moves, the light detection plate 5 is driven to move synchronously through the moving motor 61;

[0095] When the illumination detection plate 5 moves to the desired illumination detection point, the moving motor 61 is turned off and the light source generator 7 is started. The light source generator 7 provides light source input for the installed collimating light passage mechanism 100, and the collimating light passage mechanism 100 stably irradiates the illumination detection plate 5 with light.

[0096] The double-layer multi-hole collimated light flux auxiliary detection device provided by the present invention has the following beneficial effects:

[0097] By installing the formed collimating light transmission mechanism 100 on the clamping mechanism 8, and aligning the light source input end of the collimating light transmission mechanism 100 on the light source generator 7, a movable light detection plate 5 is provided on the support frame 4, which facilitates the detection of the illumination range of the collimating light transmission mechanism 100 at different points without manual movement, and facilitates the rapid and stable adjustment of the detection points.

[0101] By adding an infrared sensor 91 to the irradiation end of the light source generator 7, it is convenient to sense the human body within the illumination range. After sensing, the light source generator 7 is automatically controlled to shut down, providing support for the safe operation of the equipment. When the collimating light path mechanism 100 is not installed, the light source generator 7 and the infrared sensor 91 are automatically shut down to avoid accidental startup of the equipment.

The infrared sensor 91 is activated and the light source generator 7 is activated.

[0107] The working principle of the double-layer multi-hole collimated light flux auxiliary detection device provided by the present invention is as follows:

The infrared sensor 91 is activated, and the light source generator 7 is activated.

[0110] In the working state of S3 irradiation detection, when a human body blocks the irradiation range, the infrared sensor 91 detects the human body, and the control end of the light source generator 7 is turned off, and the light source cannot irradiate normally, avoiding the light source from irradiating the human eyes and improving the safety of the equipment operation.

[0111] The double-layer multi-hole collimated light flux auxiliary detection device provided by the present invention has the following beneficial effects:

[0112] By adding an infrared sensor 91 to the irradiation end of the light source generator 7, it is convenient to sense the human body within the illumination range. After sensing, the light source generator 7 is automatically controlled to shut down, providing support for the safe operation of the equipment. When the collimating light path mechanism 100 is not installed, the light source generator 7 and the infrared sensor 91 are automatically shut down to avoid accidental startup of the equipment.
