Problems solved by technology

This design can effectively achieve R / G / B mixed light, but this structural arrangement will affect the heat dissipation and the effective application of R / G / B colors, especially at present, red light materials are most sensitive to temperature, so the operating current will be limited, and when red If the output is limited, the Blu-ray will be a waste, and this design seems to cause more problems

Abstract

The invention relates to a luminous device comprising a base plate which comprises an upper surface and a lower surface, a plurality of extension units which comprise a red light extension unit, a green light extension unit and a blue light extension unit which are formed on preset positions on the upper surface of the base plate, and an adjoining plane formed between the base plate and the extension units. The invention further relates to the processing method of the luminous device.

Description

technical field [0001] The invention relates to a light emitting device and a manufacturing method thereof, in particular to a light emitting diode device and a manufacturing method thereof. Background technique [0002] Light-emitting diodes (LEDs) have different light-emitting principles and structures from traditional light sources, and have the advantages of small size and high reliability, and are widely used in the market. For example, optical display devices, laser diodes, traffic signs, data storage devices, communication devices, lighting devices, medical devices, and various large-scale components are made according to the requirements, so as to be applied to indoor or outdoor large-scale display screens. [0003] With the emergence of white LEDs, the application field of LEDs has stepped into the lighting source market. One of the methods of white light LED is to use UV LEDs to excite RGB three-color phosphors. Its main advantage is that only one LED chip can pr...
