GaN material-based LED chip with vertical structure and LED lamp

Abstract

The invention provides a GaN material-based LED chip with a vertical structure. The GaN material-based LED chip comprises a blue light emitting assembly, a red light emitting assembly, a common positive electrode assembly, a blue light emitting component negative electrode and a red light emitting component negative electrode, wherein the common positive electrode assembly is arranged on the bluelight emitting assembly and the red light emitting assembly, the blue light emitting assembly negative electrode and the red light emitting assembly negative electrode are arranged on the blue light emitting assembly and the red light emitting assembly respectively, and the blue light emitting assembly comprises GaN material. The method has the beneficial effects that light with multiple colors can be generated on a single chip, and the use amount of fluorescent powder is less; the integration level is improved, and the cost of the LED can be reduced; and the color temperature adjustment is more flexible.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a GaN material-based vertical structure LED chip and an LED lamp. Background technique [0002] LED light sources are more and more commonly used in the field of lighting. Usually, the LED light source emits various colors of light through the LED light-emitting chip and phosphor powder. In the prior art, a single light-emitting chip can only emit monochromatic light. To synthesize light of other colors, it is necessary to mix light-emitting chips of different colors together and fill a large amount of phosphor powder. Difficult question. In addition, strong scattering occurs when light is incident on the phosphor layer, which makes the phosphor layer absorb light, causing a large amount of light to be reflected, that is, the light transmitted through the phosphor layer will be significantly reduced. Therefore, how to design a new type of LED chip becomes extremely impo...

Problems solved by technology

In the prior art, a single light-emitting chip can only emit monochromatic light. If light of other colors needs to be synthesized, light-emitting chips of different colors need to be mixed together and filled with a large amount of phosphor powder. difficult problem

In addition, when light is incident into the phosphor layer, there will be strong scattering, which will cause the phosphor layer to absorb light, causing a large amount of light to be reflected, that is, the light transmitted through the phosphor layer will be significantly reduced.
