Problems solved by technology

Generally, when the light emitted by the LED luminescent material passes through the chip and enters the light-transmitting package, it will be refracted. The refractive index of the chip material is usually above 2.0, while the air medium has a refractive index of 1. Because there is only one layer of light-transmitting package between them Transition, resulting in a small total reflection angle of the LED, so that a large part of the light energy cannot be refracted out of the lens but reflected b

Abstract

The invention discloses a high light-emitting rate LED lamp which comprises an insulation base, a pin, a reflection cup and a light emitting chip, wherein the insulation base is provided with a concave cup with a hollow structure; the pin penetrates through the insulation base; the reflection cup is accommodated into the concave cup, and the inner surface layer of the reflection cup is made of reflection materials; and the light-emitting chip is arranged in the reflection cup and is electrically connected with the pin. The high light-emitting rate LED lamp can effectively guide light out, improves the light-emitting rate, and has good heat radiating property. The invention also discloses a manufacture method of the high light-emitting rate LED lamp.

Description

technical field [0001] The present invention relates to lighting technology, more specifically to a high light extraction rate LED lamp and a manufacturing method thereof. Background technique [0002] As a light-emitting device that directly converts electrical energy into visible light and radiant energy, LED is widely regarded as the best light source in the 21st century. It has a series of advantages, such as low operating voltage, low power consumption, high luminous efficiency, and LED itself And its production process is pollution-free, and its performance is stable and reliable. [0003] In the LED lighting technology, in order to improve the light extraction efficiency of the LED and facilitate the use, it is generally necessary to package the LED chip. The LED package structure in the prior art generally includes an LED chip, a bracket for carrying the LED chip, and a light-transmitting package (lens) for encapsulating the LED chip. Generally, when the light emit...
