Description

Technical Field

[0001] The utility model relates to the technical field of LED light sources, in particular to an LED light source board with stable light emission. Background Art

[0002] LED refers to Light Emitting Diode, which is what we often call light-emitting diode. In layman's terms, it is the carriers injected into the PN junction. After the minority carriers and majority carriers recombine, they release energy in the form of light, thereby realizing electroluminescence. This kind of product and its application are not new, and its application can be seen everywhere in our real life. For example, roadside billboards, various colored indicator lights on household appliances and backlighting on mobile phone keyboards all use LED as the light source. LED has gradually replaced traditional incandescent lamps and fluorescent lamps because of its energy saving, high efficiency and environmental protection.

[0003] After searching, the Chinese utility model patent application number CN202220048723.9 discloses an LED light strip, comprising a substrate, the substrate being in the shape of an elongated strip and comprising a first surface and a second surface; a first power supply circuit and a second power supply circuit being provided on the first surface of the substrate; the first power supply circuit and the second power supply circuit being arranged at intervals along the length of the substrate; at least one LED light-emitting branch being provided between the first power supply circuit and the second power supply circuit; the LED light-emitting branch being arranged along the length of the substrate; the LED light-emitting branch containing at least one LED light-emitting tube; one end of the LED light-emitting branch being electrically connected to the first power supply circuit and the other end being electrically connected to the second power supply circuit. This LED light strip can be manufactured to a fixed length during production, and can be shortened as needed without affecting its functionality during use, or it can be cascaded to increase its length as needed.

[0004] Another example is Chinese utility model patent application number CN202220677897.1, which discloses an LED light bar structure comprising multiple LED light source assemblies. Each light source assembly includes a light bar plate, a current-limiting resistor, and at least two LED light sources. The light bar plates of the multiple light source assemblies are connected in series; at least two LED light sources are connected in series with the current-limiting resistor; and the LED light sources of each light source assembly are connected in series. This LED light bar structure utilizes a current-limiting resistor in each light source assembly group to maintain a constant current, ensuring consistent and uniform illumination from each LED light source.

[0005] However, the wiring of the above-mentioned existing LED light strips is not reasonable enough, and there are defects in the production and use process, such as complex production process, high production cost, unstable use, difficult installation and poor lighting effect, which brings trouble to users and limits the scope of application. Further improvement is needed. Utility Model Content
