Problems solved by technology

In order to better meet the higher color gamut (greater than NTSC80%) requirements of smartphones and other terminals, the more commonly used technology is to excite red and green phosphors with blue LED chips. Due to the low excitation efficiency of red phosphors, the light of LEDs The efficiency level is low, the color gamut is difficult to achieve more than NTSC90%, and the cost is high

Abstract

A light emitting component based on an LED chip comprises a base (1) having a receiving cavity (11), and a group consisting of a red-light LED chip (2), a blue-light LED chip (3) and a green-light LEDchip (4) which are arranged in the receiving cavity (11). The receiving cavity (11) has an opening (12) on one side. The red-light LED chip (2), the blue-light LED chip (3) and the green-light LED chip (4) are disposed in a preset arrangement manner at different heights along the same axis in a direction from the opening (12) of the receiving cavity (11) to the bottom (13). The three LED chips are arranged at intervals on different heights in the axial direction of the receiving cavity (11) so as to enlarge a light mixing area and improve the light mixing uniformity.

Description

technical field [0001] The present application relates to the field of light emitting diodes, in particular to a light emitting assembly based on LED chips. Background technique [0002] As a backlight source, light emitting diodes (Light Emitting Diode, LED) have been widely used in backlight fields such as mobile phones, tablet computers, and notebook computers. In order to better meet the requirements of a higher color gamut (greater than NTSC80%) required by terminals such as smart phones, the more commonly used technology is that blue LED chips excite red and green phosphors. Due to the low excitation efficiency of red phosphors, the LED light The efficiency level is low, the color gamut is difficult to achieve more than NTSC90%, and the cost is high. In order to be more suitable for smart phones and tablet computers to improve color fidelity, full-color side light-emitting diodes are generally used now. Red LED chip, green LED chip and blue LED chip, the cavity is fi...
