Problems solved by technology

[0004] Since the wavelength conversion part 3' only covers the upper surface of the LED chip 1', the emitted light after excitation and conversion is directional, and even after being diffused by the light-transmitting part 4', the light distribution angle is generally below 120° , the back where the light cannot reach, will form a dark shadow
[0005] Moreover, since the wavelength conversion layer 3' usually exists in the form of a film or a sheet, the thickness is relatively thin, and the volume is small. During the preparation process, due to the inconsistent specific gravity and properties of materials such as phosphors and colloids, sedimentation and uneven dispersion are prone to occur. Phenomenon, resulting in poor product consistency, the same batch of packaged light sources, the color temperature deviation is large, it is difficult to control

Abstract

The present invention provides a full -week light source LED light source and its preparation method. The full week's LED light source includes a pin bracket, which consists of a plane body and two pins; LED chip; wavelength conversion department; LEDThe chip is fixed on the plane main body of the pin bracket through the welding wire; together with the plane subject, it is packaged in the middle of the wavelength conversion part., Negatively connected.The full weekly LED light source of the present invention, by encapsula the LED chip in the wavelength conversion department, achieves 360 ° full -week light, and its structure is simple. At the same timeWhen a chip is encapsulated together, the accuracy is easy to control during the manufacturing process, and the consistency of color temperature can be improved.The preparation method of the present invention is simple, easy to quality control, good product accuracy, uniform color temperature, and consistency is improved.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to a full-circumference LED light source and a preparation method thereof. Background technique [0002] LED light-emitting diodes have been recognized worldwide as the most efficient artificial lighting technology.
