Description

Technical Field

[0001] The utility model specifically relates to a novel LED point light source, belonging to the technical field of distribution box application. Background Art

[0002] LED point light source is a small light source with a diameter of several millimeters, usually composed of dozens to hundreds of LED chips. It has the advantages of high brightness, small size, convenience and low power consumption, so it is widely used in many fields such as machine vision, architectural lighting, landscape lighting, billboard lighting, exhibition and stage performance, and home lighting. The working principle of LED point light source is based on the electroluminescent effect of LED. When current passes through the light-emitting diode, electrons jump to the valence band and release energy, resulting in the emission of photons and light emission. In order to control and focus the output of the light beam, LED point light sources are also equipped with lenses or reflectors. In addition, they usually contain a fixed electric drive circuit to stabilize the current and protect the LED from overheating and voltage surges.

[0003] The existing application number is 202221979646.5. A point light source and a lamp, the point light source includes a shell and a light-emitting circuit encapsulated in the shell, the light-emitting circuit includes a constant current control chip and a plurality of monochromatic light strings, each monochromatic light string is composed of a plurality of light-emitting elements connected in series, the constant current control chip is used to respond to an external serial signal to generate a pulse signal transmitted to each monochromatic light string, so as to change the luminous brightness of each monochromatic light string accordingly through each of the pulse signals. The point light source controls the current flowing through the point light source through the constant current control chip, so that the current flowing through each point light source of the point light source lamp is consistent, so that the luminous brightness of each point light source of each point light source lamp is the same, avoiding the luminous brightness of each point light source of the point light source lamp being different and affecting the visual effect.

[0004] The above-mentioned device improves the uniformity of brightness of each point light source when it is working. It and the traditional point light source both use circuits to reduce the working heat of the LED. The cooling effect is poor and limited. When used for a long time, a large amount of heat will still be generated, affecting the operation of the device and reducing the service life of the device. There is no fixed structure when the light source is connected to the cable, and it is easy to disconnect, affecting the use of the device. Utility Model Content
