Bracket capable of improving chroma uniformity, a light-emitting diode (LED) and manufacturing method

Abstract

The invention discloses a bracket capable of improving chroma uniformity, a light-emitting diode (LED) and a manufacturing method. The bracket comprises a first bracket body, wherein a plurality of micro-structures for reflecting rays are arranged on the inner surface of the bracket body. The plurality of micro-structures are arranged on the inner surface of the bracket; and the ray emitted from an LED chip can be scattered relatively evenly through the micro-structures, so that the excitation effect of each position in the LED is relatively consistent to improve the chroma uniformity of the LED.

Description

technical field [0001] The invention relates to the technical field of semiconductor electronics, in particular to a bracket for improving chromaticity uniformity, an LED and a manufacturing method. Background technique [0002] LEDs are widely used in backlight modules due to their advantages of greenness, energy saving, environmental protection, and stable performance. When used in direct-lit backlight modules, LEDs generally need to be used with a secondary lens. The secondary lens can make the brightness and chromaticity distribution more uniform. At present, most commonly used LEDs use GaN blue light chips to excite yellow phosphors, so the main components of the white light produced are blue light and yellow light. [0003] Such as figure 1 As shown, commonly used LEDs include LED chip 110, bracket body 100, fluorescent powder 130, silica gel and gold wire, etc., and LED chip 110 is usually put into the center of bracket body 100 when packaging, and then placed in t...
