LED (light-emitting diode) lamp and LED light source component

Abstract

The invention discloses an LED (light-emitting diode) lamp and an LED light source component. The LED light source component comprises a PCB (printed circuit board) and a plurality of LED light sources. A conductive circuit layer is arranged on one side of the PCB, and a plurality of first openings are formed on the PCB. Each LED light source is correspondingly arranged in one first opening and electrically connected with the conductive circuit layer. The light emergent surface of each LED light source is positioned on the other side, which is opposite to the conductive circuit layer, of the PCB. Through the way, the LED light sources are accommodated in the first openings, so that the fixing effect of the LED light sources can be improved and the mounting height can be reduced; and by further enabling the light emergent surfaces of the LED light sources to be positioned on the other side, which is opposite to the conductive circuit layer, of the PCB, the appearances of the LED light source component and the LED lamp can be simpler and more aesthetic. Furthermore, the LED light sources are in direct contact with a heat radiation body, so that the direct heat resistance between the LED light sources and the heat radiation body is reduced and the heat radiation effect of the LED light sources is improved.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED lamp and an LED light source assembly. Background technique [0002] With the development and popularization of LED lighting technology, LED lamps have gradually become the first choice for lighting in various places. In existing LED lamps, a conductive circuit layer is provided on one side of the PCB circuit board, and then a plurality of LED light sources are provided on the same side of the conductive circuit layer of the PCB circuit board, and the pins of the LED light sources are connected to the conductive circuit layer by welding. The circuit layer is electrically connected and fixed. However, in this design, the LED light source is fixed only through the solder joint between the pin and the conductive circuit layer, so the fixing effect is relatively poor. In addition, the LED light source protrudes from the PCB circuit board, which increases the installation height, ...

However, in this design, the LED light source is fixed only through the solder joint between the pin and the conductive circuit layer, so the fixing effect is relatively poor

In addition, the LED light source protrudes from the PCB circuit board, which increases the installation height, and the pins, the conductive circuit layer and the solder joints between them and the light-emitting surface of the LED light source are located on the same side of the PCB circuit board, and the observer can see it from the outside. Due to the above components, the appearance of LED lamps is not simple and beautiful
