Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0022] ginseng figure 1 As shown, in the first embodiment of the present invention, the LED light-emitting device includes a transparent substrate 1, and the material of the transparent substrate 1 is preferably glass. A plurality of grooves 2 are formed on the surface of the transparent substrate 1 , each groove 2 is provided with an LED chip 3 respectively, and the LED chips 3 are connected in series.

[0023] The LED chip 3 includes a transparent substrate, an epi...

Abstract

The invention discloses an LED light-emitting device, which comprises a transparent substrate, at least one groove is distributed on the transparent substrate, and an LED chip is arranged in each groove, and the LED chip includes a transparent substrate and An epitaxial layer formed on the transparent substrate, the epitaxial layer is provided with a transparent conductive layer, and the transparent conductive layer extends at least to the transparent substrate. With the design of the present invention, it is possible to realize the 4π solid angle of the LED light-emitting device to emit light throughout the body, and the light efficiency is high (the efficiency of the general 2π solid angle lamp is increased by more than ~20%). At the same time, it is possible to produce light-emitting modules with different voltages at low cost. High reliability, easy to standardize production in large quantities.

Description

technical field [0001] The present invention relates to a semiconductor light-emitting device, in particular to an LED light-emitting device. Background technique [0002] In the 1960s, the first LED product was born in the United States, and its appearance brought a lot of brilliance to people's lives. Because LED has the advantages of long life, low power consumption, green environmental protection, etc., the related technology has developed very rapidly. . It has become a "ubiquitous" optoelectronic device and light source that is closely related to our lives, such as mobile phone backlights, traffic lights, large-screen full-color displays and landscape lighting lights, etc. [0003] At present, the bottleneck restricting the further application and development of LEDs is its price, luminous efficiency and heat dissipation. In theory, the luminous efficiency of white light synthesized by exciting yellow phosphors with blue LEDs is as high as more than 300 lumens per wat...
