Problems solved by technology

However, because the phosphor layer 26 of the LED lamp bead 2 is glued with the adhesive layer 100, the light emitted by the LED lamp bead 2 must pass through the adhesive layer 100 to enter the LED lens 3, and the adhesive layer 100 will change the light emitted by the LED lamp bead 2. The light path of the light will seriously affect the optical taste of the LED light bar, and then affect the display effect of the LCD

Abstract

The invention discloses a direct-light type LED light bar, and the light bar comprises a substrate, an LED lamp bead disposed on the substrate, and an LED lens covering the LED lamp bead. A first bonding layer is disposed around the incident light surface of the LED lens, and is used for sealing a fluorescent powder layer of the LED lamp bead. The light bar is enabled to be better in oxygen resistance and humidity resistance under the condition that the optical attribute of the LED light bar is not affected. The invention also provides a manufacturing method for the light bar.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a direct-lit LED light bar and a manufacturing method thereof. Background technique [0002] Liquid crystal display (LCD, Liquid Crystal Display) is widely used in electronic equipment due to its characteristics of low power consumption, no radiation, large viewing area, fine picture quality, and stable color of the picture. The liquid crystal display is mainly composed of a liquid crystal display and a backlight module. The liquid crystal molecules in the liquid crystal display change their arrangement order under the action of an electric field. The backlight module produces sufficient brightness and uniform light through the liquid crystal display. The liquid crystal molecules change the optical path of the transmitted light and modulate the light, so that the liquid crystal display presents an image picture. [0003] Generally speaking, according to the position of the backligh...
