Abstract

This invention arranges at least one fluorescence material with fixed wavelength at the bottom and above the periphery of the luminous chip, when the luminous chip electrifies, it actives the luminous chip to form colored light with high luminous efficient, which can avoid disturbance, and because the fluorescence material's deal and proportion of different parts are easy to control, so this method is benefit for controlling the quality of the multi-wavelength radiation dipolar and its production.

Description

technical field

[0001] The invention relates to the luminous efficiency and light color performance technology of light-emitting diodes, aiming to provide a multi-wavelength light-emitting diode structure and manufacturing process capable of producing high luminous efficiency and accurate gloss. Background technique

[0002] Such as figure 1 As shown, it is a schematic diagram of the basic structure of a conventional multi-wavelength light-emitting diode. This multi-wavelength light-emitting diode uses a die-bonding glue 40 to fix the light-emitting chip 10 in a bowl-shaped carrier 20, and uses gold wires 30 to form a light emitting diode. The chip 10 is connected to the electrode terminal 21, and the light-emitting chip 10 is coated with the fluorescent glue 50 having phosphor powder, so that the light source of the light-emitting chip excites the phosphor powder of the fluorescent glue 50 under the power-on action of the light-emitting chip 10, so as to form the desired l...
