Abstract

The invention discloses a directly embedded high-power LED illumination module comprising a printed circuit board (PCB), an LED module and a constant-current driving module. The LED module and a constant-current driving module are connected and directly embedded on the surface of the PCB; the LED module comprises an LED chip and a copper diffuse-reflection lamp cup; the copper diffuse-reflection lamp cup comprises a copper cup body and an inwards concave reflection cup cavity arranged on the top of the copper cup body; a cup seat of the copper diffuse-reflection lamp cup is embedded inside the PCB, and the reflection cup cavity exposes out of the PCB; and the LED chip is arranged inside the reflection cup cavity. The invention adopts a chip directly embedded strategy and the technology ofthe copper diffuse-reflection lamp cup, thereby reducing the assembly cost, improving the heat conduction efficiency, realizing non-epoxy beam transformation, greatly enhancing the external quatum efficiency of white light LED and avoiding serious light decay caused by etiolation of ethoxyline resin.

Description

technical field [0001] The invention relates to the application field of LED lighting, in particular to a direct-embedded high-power LED lighting module. Background technique [0002] In the 1960s, scientific and technological workers developed LED light-emitting diodes by using the principle of semiconductor PN junction to emit light. The LED developed at that time was made of GaASP, and its luminous color was red. After nearly 30 years of development, LEDs, which are now very familiar to everyone, can emit red, orange, yellow, green, blue and other colored lights. However, the white light LED used for lighting has only been developed in recent years. For general lighting, white light LEDs are generally formed in two ways in terms of process structure. The first is to use "blue light technology" to cooperate with phosphors to form white light; the second is to mix multiple monochromatic lights. Both approaches have successfully produced white light devices. [0003] Whi...
