Problems solved by technology

Not only the loss of light energy is large, but also the uniformity of luminous intensity is poor, especially the higher the luminous intensity of LED point light sources, the greater the direct glare, which brings greater difficulties to the secondary optical design

Embodiment 1

[0020] Embodiment 1, with reference to figure 1 , the strip-shaped metal substrate 1 has a crystal-bonding area 2 and a bonding wire area 4 . Wherein the bonding wire area 4 is a plating layer processed after an insulation treatment on the metal substrate 1 , and has higher insulation requirements with the metal substrate 1 . The crystal-bonding area 2 is a groove with a specular reflection layer after prescribed processing. exist figure 2 In the above, since the bottom surface of the groove is a tangential circle, the bottom surface of the groove is connected to a line when viewed from the center line, and the bottom surface is already a continuous plane with a linear order of magnitude more than a centimeter relative to the micron-scale chip, and then the chip 3. Die bonding is in the center of the groove, and the positive and negative electrodes of the chip are led to the bonding wire area 4 with bonding wires. Finally, from a microscopic point of view, the chip 3 and th...

Abstract

The present invention discloses high power LED expansion light source, belonging to an electronic component, in particular a high power LED expansion light source component made from low power LED. It contains setting solid crystal zone formed by same continue plane and capable of setting several chips, packaging to one continue integral by epoxy or silica gel. Different inclined angle incline or paraboloid can be designed on side of solid crystal zone, according to different uses requirement of expansion light source. Said invention has advantages of effective heat sinking effect, high and uniform luminous intensity and colour temperature with low cost and simple technology.

Description

technical field [0001] The invention relates to an electronic component, in particular to a high-power LED extended light source component made of a low-power chip. Background technique [0002] Currently widely used LED light sources have low power and low luminous intensity, which cannot meet the needs of practical applications. Although high-power LED light sources have been developed and applied, there are many problems in high-power LEDs that cannot be widely used; for example, the heat dissipation problem greatly reduces the service life of LED products. In addition, high-power LEDs are also a kind of point light source. With the continuous improvement of high-power LED luminous efficiency, the direct glare of illuminants is getting bigger and bigger. In many occasions, we need not only high-power LED point light sources, but also high-power line light sources and surface light sources with small direct glare or extended light sources with various shapes. Although the...
