Light emitting diode with good light radiation and color development

Abstract

The invention belongs to chemical and electronic technical field. A plastically-packaged LED chip is a solid comprising a top as a single sided concave lens, a semi-transparent reflective layer, a top periphery as a single sided concave lens, a lateral periphery as taper and a small annular ditch, a bottom as a concave spherical reflective layer, covered red fluorescent layer of the reflective layer; the outer edge is composed of a concave spherical surface at the top and the top periphery, a cylindrical surface ad the lateral periphery; the inner edge is composed of a semispherical hole, a shallow circular ring on the semispherical hole as the lateral periphery; the top and the top periphery of the inner edge covered with the green reflective layer is the double sided shell of the concave lens. After the solid is sleeved in the shell for locking, the invention forms the light emitting diode with great light radiating development.

Description

technical field [0001] The invention belongs to the field of optical and electronic technology. Background technique [0002] Due to the small size, low power consumption and long life of light-emitting diodes (abbreviated as LEDs), it is expected that the era of using them as lighting fixtures will come soon. But at present, LED has not yet replaced incandescent lamps, fluorescent lamps, and energy-saving lamps to enter the lighting market. In the process of implementing "High Brightness Light-Emitting Diode Lamp Bulb with Built-in Reflective Layer" (Patent No. ZL200620070108.9), we were troubled by the fact that the light emitted by the LED chip is basically in one direction and the color rendering is poor. The light emitted by the bulb is like a spotlight: bright under the lamp, dark around, cold light source color, poor color rendering, and the original colors of people and objects are distorted, which is not welcomed by everyone. In order to change the defects of the ...
