Embodiment

[0031] Such as figure 1 As shown, the LED5050 module based on high-voltage constant-current technology mainly includes three parts: a high-voltage DC regulated power supply, a constant-current module, and a light-emitting LED lamp group. Among them, the high-voltage DC stabilized power supply adopts 36V power supply, and in the LED industry, the voltage for powering LED lamps is always higher than the LED tube voltage drop, that is, it is always greater than 5V, and the general high voltage is 12V and 24V. By configuring a 36V high-voltage power supply, it lays the foundation for realizing long-distance power supply and saving power consumption on the transmission line.

[0032] The constant current module is a major design in the present invention. Because the existing technology does not use constant current technology, the current on the light-emitting LED single lamp often fluctuates due to the influence of voltage attenuation, which makes it difficult for the light-emitt...

Abstract

The invention discloses an LED (light-emitting diode) 5050 module based on a high voltage constant current technology, which is characterized in that the LED 5050 module comprises two groups of LED single lamps in parallel connection, a constant current module, and a high voltage direct current stabilized voltage supply connected with an input end of the constant current module, wherein each LED single lamp comprises an LED secondary light distribution lens, an injection molding housing located below the LED secondary light distribution lens and forming an integral structure with the LED secondary light distribution lens through injection molding, a PCB (printed circuit board) located in the injection molding housing, an LED 5050 located on the upper surface of the PCB, and a voltage stabilizing diode in reverse parallel connection with the LED 5050; the voltage stabilizing diodes are communicated with an output end of the constant current module by wires. According to the LED 5050 module, with the improvement of the inner LED single lamps and the design of the constant current technology, all the LED single lamps emit light uniformly, the convenience of mounting and maintenance is improved, the overall performance of the LED module is improved, and the LED 5050 module has higher practical and popularization values.

Description

[0001] technical field [0002] The invention relates to an LED lamp group, in particular to an LED5050 module based on high voltage constant current technology. Background technique [0003] In recent years, the LED advertising sign industry has achieved rapid development. With the rising awareness of global energy conservation and the background of relatively high electricity prices compared with traditional light sources, LED light sources continue to be introduced into commercial, architectural, and advertising signage fields. As a branch of LED advertising signs, a kind of LED outdoor luminous characters has many advantages such as beautiful in the daytime, bright in the night, energy saving, durable and so on. The core of this outdoor advertising luminous word project lies in the LED module system. [0004] At present, the LED module light source of outdoor advertising luminous characters mainly uses straw hat LED lights as the light source, which mainly has the ...
