LED light-emitting assembly, LED support and manufacturing method of LED light-emitting assembly

Abstract

The invention relates to an LED light-emitting assembly, an LED support and a manufacturing method of the LED support, a first die bonding area and a second die bonding area are arranged on the front face and the back face of a bearing substrate of the LED support respectively, and a first base and a second base of a first concave part and a second concave part are formed on the first die bonding area and the second die bonding area respectively; the first LED chip and the second LED chip are arranged in the first concave part and the second concave part respectively, so that the manufactured LED light-emitting assembly can emit light from the front face and the back face respectively, the sum of the light-emitting angles of the first LED chip and the second LED chip on the front face and the back face can be larger than 180 degrees, and the light-emitting brightness can be two times that of an LED lamp bead emitting light from a single face. Therefore, the light-emitting angle and brightness of the LED light-emitting assembly can be improved, and the LED light-emitting assembly can be applied to various application scenes needing larger light-emitting angles and brightness. And the color temperature, the light emitting color and the like of the first LED chip and the second LED chip can be flexibly set according to application requirements, so that the adjustability of the color temperature and the light emitting color is better.

Description

technical field [0001] The invention relates to the field of lighting, in particular to an LED lighting assembly, an LED bracket and a manufacturing method thereof. Background technique [0002] Light sources such as LED lamp beads made by using patch brackets have broad application scenarios, such as mature applications in the fields of lighting and backlighting. At present, all kinds of LED light source devices using brackets with reflective cups emit light from one side. For example, the models 3014, 4014, 7020, 4010, 2835, 3030, and 2016 on the market all emit light from one side. That is, the reflective cup and the LED chip are arranged on the front of the bracket, and the electrodes of the LED chip are led to the pins on the back of the bracket for welding. This structure makes the LED lamp bead only emit light on one side, and the realized light angle is less than 180 degrees, which limits its application scenarios; and only a single LED chip can be set on the front ...
