Abstract

The invention relates to a high-brightness small-sized condensation LED. The brightness of the small-sized LED can be effectively improved, the irradiation distance can be lengthened, average illuminance can be enhanced, the high-brightness small-sized condensation LED is anti-glare and strobe-preventive and has a condensation effect, eyesight of a user is protected, the color rendering index is increased, and colors of an articles are truly displayed. An LED luminous chip is positioned on a wedge-shaped support, the wedge-shaped support is a bowl-shaped reflecting cavity, and a reflecting nanometer layer is disposed on the inner wall of the bowl-shaped reflecting cavity. The high-brightness small-sized condensation LED has the advantages that firstly, the irradiation distance of the LED is effectively lengthened, and the brightness and the average illuminance are improved, secondly, the manufactured LED is anti-glare and strobe-preventive, the eyesight of the user is protected, the rendering index is increased, and the colors of the articles are truly displayed, thirdly, the high-brightness small-sized condensation LED has a directional illuminating condensation effect, and fourthly, electrical-to-optical conversion efficiency of the small-sized light emitting diode is effectively enhanced.

Description

technical field [0001] The invention relates to a device that can effectively improve the brightness of small-sized LED light-emitting diodes, prolong the irradiation distance, improve the uniform illuminance, prevent glare, resist strobe, protect eyesight, improve the color rendering index, and have the effect of concentrating light and truly expressing the color of objects. The utility model relates to a high-brightness small-sized concentrated LED diode, which belongs to the field of LED light-emitting diode manufacturing. Background technique [0002] At present, the small LED light-emitting diodes (diameter below 5mm) manufactured by the existing technology, in terms of structural design, the LED light-emitting chip is placed on a shelf with leads, and then sealed with epoxy resin around it to protect the internal core wire. , so the shock resistance of LED is good. The core part of a light-emitting diode is a wafer composed of a p-type semiconductor and an n-type semi...
