Abstract

The invention discloses a light emitting diode for increasing luminous efficiency. The light emitting diode comprises a light emitting diode chip and an optical layer at the bottom of the light emitting diode chip, wherein the optical layer can be a light layer, a light reflecting layer or an energy conversion layer so as to increase the luminous efficiency of the light emitting diode; and a roughened layer is further arranged between the light emitting diode chip and the optical layer to increase the surface area of the light emitting diode chip; and thus the light emitted from the light emitting diode chip can easily enter the optical layer so as to further increase the luminous efficiency of the light emitting diode. The luminous efficiency of the light emitting diode can be effectively increased by using the light emitting diode of the invention.

Description

technical field [0001] The invention relates to a light-emitting diode, especially a light-emitting diode with increased luminous efficiency. Background technique [0002] A light-emitting diode (Light Emitting Diode, LED) is a light-emitting element made of semiconductor materials. The element has two electrode terminals. A voltage is applied between the terminals, and a very small current is passed through. The remaining energy can be released by the combination of electrons and holes Stimulate and release in the form of light, which is the basic light-emitting principle of light-emitting diodes. Light-emitting diodes are different from ordinary incandescent light bulbs. Light-emitting diodes are cold-emitting, with low power consumption, long component life, no warm-up time, and fast response. In addition, they are small in size, resistant to vibration, and suitable for mass production. It is easy to make extremely small or arrayed components to meet the needs of the app...
