Technical Field
[0001] This utility model relates to the technical field of surface light sources, and in particular to an ultra-high power surface light source based on a surface light source module array. Background Technology
[0002] A surface light source is an optical device or light emitter that can uniformly diffuse light from the entire surface. The core characteristic of a surface light source is that the surface light source emits a light beam -> the light beam passes through the air -> the light beam hits the surface of the irradiated area and forms a light field of a certain shape (such as a rectangle).
[0003] Currently, consumers in the market expect surface light sources to achieve breakthroughs in performance, including higher power, higher brightness, wider field of view, longer range, and higher uniformity, to better meet the lighting needs of various scenarios. (For example, in outdoor operations, surface light sources with a wider field of view and higher power (higher brightness, longer range) are needed to generate a brighter rectangular light field for outdoor work; the same principle applies to film and television production. In some industrial inspection fields, a wider field of view means improved inspection efficiency, avoiding the need for installation and mutual adjustment of various inspection light sources; higher power (higher brightness) means higher inspection accuracy, enabling wider adaptation to any low-light inspection scenario; and high uniformity is a fundamental performance requirement for surface light sources. Generally, the high uniformity of the surface light source should be considered first before considering the performance requirements of higher power, higher brightness, wider field of view, and longer range.)
[0004] Therefore, in the field of surface light source technology, existing technologies for achieving breakthroughs in surface light source performance such as higher power, higher brightness, wider field of view, longer distance, and higher uniformity typically include the following two approaches:
[0005] 1. A high-brightness surface light source is formed by combining a single integrated COB light source with a higher power optical structure.
[0006] 2. The integrated COB light source described in 1 above is used in a distributed, modular combination.
[0007] The aforementioned technical methods for achieving performance breakthroughs in surface light sources with higher power, higher brightness, wider field of view, and longer distance have the following technical drawbacks:
[0008] 1. Single integrated COB light source: The high power of a single integrated COB light source has physical limits, and it cannot simultaneously meet the performance requirements of higher power, higher brightness, wider field of view and longer distance.
[0009] 2. When using integrated COB light sources in a distributed and combined manner, if each integrated COB light source is too close to the others, heat dissipation defects may occur, resulting in the overall power of the combination being unable to reach its potential. Moreover, even if each integrated COB light source is too far apart, each integrated COB light source is equivalent to a point light source, which can easily cause uneven light spots, brightness breaks, and the formation of a surface light source with varying brightness, making it unsuitable for the field of surface light sources.
[0010] Therefore, there is an urgent need in the existing market for a surface light source with ultra-high power, higher brightness, wider field of view, longer distance, and high uniformity. Utility Model Content

[0019] Preferably, each of the surface light source modules is electrically connected to a power cord at one end.

[0034] The technical solution 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 scope of protection of the present invention.
[0035] Example 1:
[0036] Please see Figures 1 to 6 Embodiment 1 of this utility model provides an ultra-high power surface light source based on a surface light source module array, including a surface light source housing 1. The surface light source housing 1 has an array of NxN surface light source modules 2, where N is an integer greater than or equal to 2. Each surface light source module 2 includes a module housing 21. The module housing 21 has an opening in the mounting cavity 22. A high-power COB light source 23 and several imaging lenses are sequentially mounted on the mounting cavity 22. A diffuser plate 3 is mounted on one end of the surface light source housing 1.
[0037] The surface light source housing has a rectangular structure. The surface light source housing includes a base plate 11 and side plates 12 mounted around the base plate 11. A mounting groove 13 is formed at one end between the four side plates 12, and the diffuser plate 3 is snapped into the mounting groove 13.
[0038] Each surface light source module 2 is equipped with a positioning base plate 11111 at one end. Each positioning base plate 11111 is mounted on the base plate 11 and is fixed to the base plate 11 by bolts. Each positioning base plate 11111 has a marking number, which facilitates the manufacturing personnel to perform factory testing on each surface light source module 2.
[0039] The mounting cavity 22 of the module housing 21 of the surface light source module 2 contains three imaging lenses. These three lenses include a first plano-convex lens 24, a second plano-convex lens 25, and a third plano-convex lens 26. The high-power COB light source 23, the first plano-convex lens 24, the second plano-convex lens 25, and the third plano-convex lens 26 are mounted sequentially from the inside out on the mounting cavity 22. More specifically, the first plano-convex lens 24 is mounted at one end of the COB light source, the second plano-convex lens 25 is mounted on one side of the first plano-convex lens 24, and the third plano-convex lens 26 is mounted on one side of the second plano-convex lens 25. The high-power COB light source 23 includes a PCB board and an array of I x J LED chips arranged on the PCB board, where I and J are both integers greater than or equal to 10. Specifically, I is set to 20 chips, and J is set to 41 chips. The high-power COB light source 23 of the surface light source module 2 integrates 20x41 LED chips on a relatively small PCB board, thereby achieving high power and high brightness performance. The surface light source module 2, through the combination of the high-power COB light source 23, the first plano-convex lens 24, the second plano-convex lens 25, and the third plano-convex lens 26, emits a high-power, high-brightness light source through the high-power COB light source 23. By progressively increasing the size of the first plano-convex lens 24, the second plano-convex lens 25, and the third plano-convex lens 26, the high-power, high-brightness light source emitted by the high-power COB light source 23 can be transformed into a highly uniform surface light source with a wide field of view and long distance. Therefore, the surface light source module 2 achieves high power, high brightness, wide field of view, long distance, and high uniformity performance.
[0040] Each surface light source module 2 is electrically connected to a power cord 28 at one end. The power cord 28 is located on the outside of the surface light source housing 1. A waterproof connector 29 is sleeved on the power cord 28. The waterproof connector 29 passes through the base plate 11 and the positioning base plate 11111 in sequence.
[0041] The surface of the diffuser plate 3 is coated with a hydrophobic film, and the outer perimeter of the diffuser plate 3 is provided with a waterproof silicone strip 4.
[0042] Several breathing valves 5 are inserted into the housing 1 of the surface light source. Specifically, several breathing valves 5 are inserted into one of the side plates 12.
[0043] The aforementioned waterproof connector 29 prevents external liquids from entering the surface light source housing 1 through the power cord 28. The hydrophobic coating on the diffuser plate 3 effectively prevents external liquids from adhering and affecting the imaging of the ultra-high power surface light source of this invention. The waterproof silicone strip 4 prevents external liquids from entering the surface light source housing 1 through the diffuser plate 3. The breather valve 5 effectively prevents condensation and water ingress inside the surface light source housing 1. The aforementioned waterproof connector 29, hydrophobic coating, waterproof silicone strip 4, and breather valve 5 all improve the waterproof performance of the ultra-high power surface light source of this invention, making it more suitable for outdoor operation scenarios or industrial testing scenarios where coolant or cooling oil is sprayed.
[0044] On the plane containing NxN surface light source modules 2, a horizontal line is provided at the center of the plane. The surface light source modules 2 on both sides of the horizontal line are set at a certain inward angle relative to the horizontal line (e.g., Figure 5 As shown), on the diagonal of the plane containing the NxN surface light source modules 2, this diagonal has a center point. At this center point, there is a central axis perpendicular to the central axis of the NxN surface light source modules 2. The light source modules on both sides of this diagonal are set at a certain inward angle relative to the central axis (e.g., Figure 6 (As shown). The purpose of this structure is to make the four surface light source modules 2 of the NxN surface light source modules 2 tilted at a certain precise tilt angle along the center (the tilt angle should not be too large), so that the highly uniform surface light of the four surface light sources moves towards the center, which can further improve the uniformity and brightness of the ultra-high power surface light source of this invention.
[0045] The present invention provides an ultra-high power surface light source based on a surface light source module array according to Embodiment 1, the technical advantages of which are as follows:
[0046] First: The surface light source module 2 itself achieves high power, high brightness, wide field of view, long distance and high uniformity performance of the surface light source through a high-power COB light source 23 and several imaging lenses;
[0047] Second: Based on the first, the first surface light source module 2 is integrated with NxN built-in arrays. By tilting the angles of the NxN surface light source modules 2 around the center inward, the ultra-high power, higher brightness, wider field of view, longer distance, and highly uniform surface light source performance of this utility model are achieved.
[0048] Example 2:
[0049] Please see Figures 5 to 6Embodiment 2 of this utility model provides an ultra-high power surface light source based on a surface light source module array. Embodiment 2 is a specific limitation of Embodiment 1, which provides an ultra-high power surface light source based on a surface light source module array. Specifically, Embodiment 2 of this utility model provides an ultra-high power surface light source based on a surface light source module array, wherein there are NxN surface light source modules 2, with N being 3. On a plane containing 3x3 surface light source modules 2, a horizontal line is provided at the center of the plane. The surface light source modules 2 on both sides of the horizontal line are set at an inward tilt angle of 1.9 ± 0.5 relative to the horizontal line (e.g., ...). Figure 5 As shown), on the diagonal of the plane containing the 3x3 surface light source modules 2, this diagonal has a center point. At this center point, there is a perpendicular axis to the central axis of the 3x3 surface light source modules 2. The light source modules on both sides of this diagonal are set at an inward tilt angle of 2.7 ± 0.5 relative to the central axis (e.g., Figure 6 (As shown). Specifically, by setting the surface light source modules 2 on both sides of the horizontal line to an inward tilt angle of 1.9±0.5 relative to the horizontal line, and setting the light source modules on both sides of the diagonal line to an inward tilt angle of 2.7±0.5 relative to the central axis, the uniformity and brightness of an ultra-high power surface light source based on a surface light source module array can be effectively improved.
[0050] 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.
