Description

technical field [0001] The invention designs an LED light source and a manufacturing method thereof. Background technique [0002] The working voltage of traditional LEDs is generally DC 3V ~ 80V. Since the lighting power supply voltage we use daily is AC 110V ~ 220V, it is necessary to obtain a corresponding lower voltage through step-down technology, and then convert AC to DC. Then convert it into a DC constant current source to drive the LED light source to work. Therefore, the LED light source must rely on the AC to DC constant current source module to emit light, and the design of the lamp must also make room for this module, so it is difficult to make the lamp compact, which is not conducive to the individual design of the lamp. In the manufacture of LED lamps, the cost of manufacturing power modules and assembly has always been relatively high, so the cost of lamps has always been high, which is not conducive to the promotion of LED lamps. The appearance of most LED...

Therefore, the LED light source must rely on the AC to DC constant current source module to emit light, and the design of the lamp must also make room for this module, so it is difficult to make the lamp compact, which is not conducive to the individual design of the lamp

In the manufacture of LED lamps, the cost of manufacturing power modules and assembly has always been relatively high, so the cost of lamps has always been high, which is not conducive to the promotion of LED lamps

The appearance of most LEDs is usually planar, which can only emit light from a surface less than or equal to 180 degrees, which is not conducive to the development of LEDs
