Description

Technical Field

[0001] This utility model relates to the field of LED chip light source technology, and in particular to a high-efficiency LED chip light source. Background Technology

[0002] With the rapid development of modern technology, the demand for light sources in various electronic devices, lighting scenarios and emerging fields has exploded. Traditional light sources, due to their low energy efficiency, large size and short lifespan, can no longer meet the diversified needs of intelligence, miniaturization and energy saving. High-efficiency LED chip light sources have emerged to meet this demand.

[0003] The core of LED chip light sources is the semiconductor chip, which typically uses compound semiconductor materials such as gallium nitride and indium gallium phosphide. When current is injected into the PN junction of the chip, electrons and holes recombine in the junction region, releasing energy and radiating it in the form of photons, i.e., electroluminescence. High-efficiency chips improve the recombination efficiency of electrons and holes by optimizing the crystal structure and doping process of semiconductor materials, reducing energy loss caused by non-radiative recombination, thereby improving the internal quantum efficiency and allowing more electrical energy to be converted into light energy.

[0004] At present, high-efficiency LED chip light sources have injected strong momentum into the development of the industry and the supply of light sources due to their high efficiency and miniaturization. However, in practical applications, they still face the challenge of the contradiction between light scattering and illuminance. Light scattering is a necessary design in the LED packaging process to achieve uniform light output. It expands the illuminated area through the diffuse reflection of phosphor particles or colloids. However, this characteristic also leads to the dispersion of light energy. When the light source is used in scenarios that require high-concentration lighting (such as industrial inspection and medical surgical lighting), scattering will reduce the luminous flux (illuminance) per unit area, resulting in the problem of "wide illumination but not bright illumination". To solve this problem, a high-efficiency LED chip light source is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency LED patch light source, which aims to improve the problem that scattering in the prior art reduces the luminous flux per unit area.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency LED patch light source includes a base plate, two rotating rods rotatably connected to one side of the base plate, a lamp array fixedly connected inside the base plate, a top plate fixedly connected to the two rotating rods, a lens fixedly connected inside the top plate, and a reinforcing component fixedly connected to the top of the top plate.

[0008] As a further description of the above technical solution:

[0009] The reinforcement component includes a reflector, the bottom of which is fixedly connected to the top of the top plate. A lampshade is fixedly connected inside the top plate, and two screws are threaded inside the top plate.

[0010] As a further description of the above technical solution:

[0011] An adhesive layer is provided at the bottom of the base plate, and three spring pads are fixedly connected to the top of the base plate.

[0012] As a further description of the above technical solution:

[0013] The top of the lamp array is in contact with the bottom of the lens, and the top of the lens is in contact with the bottom of the lamp cover;

[0014] As a further description of the above technical solution:

[0015] The inner wall of the reflector is made of a reflective material, and the lens is made of glass.

[0016] As a further description of the above technical solution:

[0017] The tops of the three spring pads are in contact with the bottom of the reflector, and the outer walls of the two screws are threaded to the inner wall of the base plate;

[0018] As a further description of the above technical solution:

[0019] The bottom of the top plate is in contact with the top of the bottom plate, and the cross-sectional shape of the screw is T-shaped;

[0020] As a further description of the above technical solution:

[0021] The reflector has a square-shaped cross-section, and both sides of the lampshade are arc-shaped.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by fixing the lamp array to the base plate, the lamp array releases parallel light after being powered on. Then, the top plate is rotated to close the base plate and is tightened with T-shaped screws to form a sealed structure. At this time, the three spring washers between the base plate and the top plate act as buffers, dispersing the squeezing force generated by the screw tightening, preventing damage to the lamp array, and effectively extending the life of the light source. After the light starts to illuminate, the diffused light is precisely focused into a high-energy beam by the glass lens with its special curvature, greatly improving the central light intensity. This focusing effect has significant advantages in industrial inspection, surgical lighting and other scenarios. It can maintain uniform illumination and focus light energy on the target area, meeting the demand for strong light in precision operations.

[0024] 2. In this utility model, after the light is focused by the lens and guided by the lampshade, the reflector on the top of the top plate, with its highly reflective inner wall, acts like a precision light reflector, capturing and reflecting the laterally diverging light to the main light output direction. Through secondary optical path optimization, the light spot range is further compressed, and the light concentration is greatly improved, effectively avoiding light energy waste. In scenarios such as supermarket shelves and outdoor signs, it can ensure accurate light projection and reduce ambient light interference. The adhesive layer design at the bottom of the base plate greatly simplifies the installation process. After peeling off the protective film, its strong adhesion can tightly adhere to materials such as metal and plastic. It can be firmly installed without complicated fixing. The "stick and use" feature not only improves installation efficiency but also ensures that the light source and the working surface are closely attached, reducing light loss and achieving stable and efficient light supply.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3This utility model provides an embodiment of a high-efficiency LED patch light source, including a base plate 1, which serves as the basic component for overall installation and support. Two rotating rods 9 are rotatably connected to one side of the base plate 1. A lamp array 3 is fixedly connected inside the base plate 1, serving as the core component of the light source. When powered on, it releases light, providing the light-emitting foundation for the entire device. The two rotating rods 9 are fixedly connected to a top plate 2, forming an openable double-layer structure for easy installation, debugging, and maintenance. A lens 4, made of glass, is fixedly connected inside the top plate 2. Due to its high light transmittance and optical refraction characteristics, it converges the parallel light emitted by the lamp array 3, making the light more concentrated and significantly improving the central light intensity. A reinforcing component is fixedly connected to the top of the top plate 2 to further optimize the light path. The reinforcing component includes a reflector 6, the inner wall of which is made of highly reflective material. The bottom of the reflector 6 is fixedly connected to the top of the top plate 2, providing stable support and ensuring stable reflection. A lamp cover 5 is fixedly connected inside the top plate 2. Two screws 8 are threadedly connected inside the top plate 2, forming a robust overall structure.

[0033] Reference Figures 2 to 4 The bottom of the base plate 1 is provided with an adhesive layer 10. This design allows the light source to be quickly and easily attached to the surface of various equipment without complicated installation tools, greatly improving installation efficiency. Three spring pads 7 are fixedly connected to the top of the base plate 1. When the top plate 2 and the base plate 1 are tightened with screws 8, the spring pads 7 can effectively buffer the squeezing force between them, preventing damage to the lamp array 3 due to excessive force, thus significantly extending the service life of the lamp array 3 and improving product reliability. The top of the lamp array 3 contacts the bottom of the lens 4, ensuring that the light can be seamlessly transmitted to the lens 4 for converging processing, reducing light transmission loss. The top of the lens 4 contacts the bottom of the lampshade 5, achieving a tight connection of optical components and ensuring the continuity of the light path. The tops of the three spring pads 7 all contact the bottom of the reflector 6, providing cushioning... While providing protection, the reflector 6 is supported and kept stable to prevent it from shifting due to external forces and affecting the reflection effect. The outer threads of the two screws 8 are connected to the inner wall of the base plate 1 to form a reliable fastening structure, so that the top plate 2 and the base plate 1 fit tightly together and firmly clamp the lamp array 3. The bottom of the top plate 2 and the top of the base plate 1 are in contact and form a complete light source cavity after closing, which effectively prevents external dust and moisture from entering and protects the internal components. The cross-sectional shape of the reflector 6 is U-shaped, which can reflect the side-scattered light back to the light output direction, reuse the light, reduce light loss, and make the lighting more concentrated. The two sides of the lampshade 5 are both arc-shaped, which can guide the light to be emitted in a predetermined direction. The auxiliary lens 4 and the reflector 6 optimize the light path and avoid light scattering.

[0034] Working principle: The lamp array 3 and base plate 1 are fixed together. The lamp array 3 is activated to release the light source. The top plate 2 is rotated until its bottom contacts the top of the base plate 1. Screws 8 are then used to firmly secure the base plate 1 and top plate 2, thus firmly fixing the lamp array 3 between them. Due to the presence of the spring washer 7, most of the force exerted by the mutual compression between the base plate 1 and top plate 2 is offset, effectively protecting the lamp array 3 and significantly extending its lifespan. The presence of the lens 4 ensures that the parallel light source produced by the lamp array 3 is... By focusing the light source, when applied to scenarios requiring high-concentration lighting, the parallel light rays converge, making the light source brighter and achieving a focusing effect, significantly increasing the central light intensity. Due to the presence of the reflector 6 on the top of the top plate 2, the light source from the lamp row 3, after being processed by the lens 4 and illuminating the lamp cover 5, is further focused, reflecting the side light to the light output direction, making the illumination of the entire patch light source more concentrated. By peeling off the film of the adhesive layer 10, the entire patch light source can be tightly adhered to the surface to be worked on, thereby achieving a tight light supply effect from the patch light source.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
