Abstract

The invention discloses a luminous unit. The luminous unit comprises an epitaxial lamination layer, at least a first electrode, at least a second electrode, a first joint sheet and a second joint sheet. The epitaxial lamination layer sequentially comprises a first semiconductor layer, a luminous layer and a second semiconductor layer; the first semiconductor layer is provided with an exposing portion which exposes the second semiconductor layer and the luminous layer; the first electrode is arranged at the exposing portion; the second electrode is arranged at the second semiconductor layer; the first joint sheet is connected with the first electrode; and the second joint sheet is connected with the second electrode. The invention also discloses two luminous units with different structures and a luminous module applying the luminous units.

Description

technical field [0001] The invention relates to a light-emitting unit and a light-emitting module thereof, in particular to an LED light-emitting unit and a light-emitting module without wiring. Background technique [0002] The purpose of light emitting diode (Light Emitting Diode, hereinafter referred to as LED) packaging is to ensure that the LED chip is electrically connected correctly, and to protect the LED chip from being affected by various external factors such as machinery, heat, and humidity. The current LED packaging has diversified packaging forms according to different application occasions, different product shapes and sizes, heat dissipation schemes, and luminous effects. [0003] The existing LED packaging technology requires a package to carry the LED die, but due to the low thermal conductivity of the package and the inconsistent thermal expansion coefficients of the LED die and the package, the components are easily damaged in a high temperature environme...
