Embodiment Construction

[0029] The present invention provides a bracket for improving chromaticity uniformity, an LED and a manufacturing method. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] A preferred embodiment of a bracket for improving chromaticity uniformity provided by the present invention, such as image 3 As shown, it includes a stent body 100 , and a plurality of microstructures 130 for reflecting light are arranged on the inner surface of the stent body 100 . The microstructure 130 can scatter the light emitted by the LED chip 110 more uniformly, so that the excitation effect of each position inside the LED is more consistent, thereby improving the chromaticity uniformity of the LED. The microstructures 1...

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...
