Abstract

An LED light bar comprises a support, an LED wafer and a PCB, the LED wafer is fixedly arranged on the support, and the support is fixedly arranged on the PCB. The LED light bar also comprises a lens in which a photoluminescent material is arranged, and the LED wafer emits light via the lens. The present invention also discloses an LED area source module comprising the above LED light bar. According to the above LED light bar and the LED area source module, and by arranging the photoluminescent material in the lens, the diffusion range of the photoluminescent material is increased substantially, the luminescent efficiency of the LED light bar and the LED area source module is improved, and the LED light bar and the LED area source module emits light uniformly.

Description

Technical field [0001] The present invention relates to the field of LED technology, in particular to an LED light bar and an LED surface light source module. Background technique [0002] With the development of LED technology, LEDs are increasingly used in lighting and TV backlighting. At present, the main process method for preparing LED light bars is: white light LED light beads are bonded to the PCB board by reflow soldering, and the white light LED light beads are pasted on the top of the white light LED lamp beads to make the light bar, and then matched with the back plate, reflector, and diffuser. Plates, optical films, etc. constitute modules. Common white LED lamp beads realize white light emission through the LED chip in the LED lamp beads and the photoluminescent material encapsulated in the bracket. [0003] The photoluminescent material is encapsulated in the bracket. Due to the limited volume of the bracket, when the photoluminescent material and glue are mixed and...
