The embodiment of the present invention provides a kind of red-light LED lamp bead and its manufacture method and adds red fluorescence powder using blue chip
It is packaged, so as to realize feux rouges, possesses the function as traditional red light chips, cost ratio is low using red light chips, and
Due to voltage and blue green light lamp bead voltage always, in circuit design, also obvious more traditional feux rouges designs well.
Refering to shown in Fig. 1, Fig. 2, red-light LED lamp bead of the embodiment of the present invention includes support 1, the indigo plant being arranged on support 1
Optical chip 10, connection blue chip 10 cause the bonding wire 12 of circuit communication and the phosphor powder layer 11 of red with support 1.
Wherein, support 1 is used for fixed chip 10 and carrying fluorescent material 11, and electric current is imported into chip top, chip
Caused heat derives are come.In the present embodiment, the support is formed by support material by plating, and support is element from inside to outside
Material, copper, nickel, copper, this five layers of silver are formed.The support can be band cup support or flat-headed support.
Blue chip 10 is mainly used for lighting, and is made up of luminous semi-conducting material.Such as can use gallium phosphide
(GaP), the material such as gallium aluminum arsenide (GaAlAs) or GaAs (GaAs), gallium nitride (GaN) is formed, and its internal structure, which has, unidirectionally to be led
Electrically.Chip includes weld pad, and in the embodiment of the present invention, the weld pad is gold pad or aluminium pad, pad shapes for it is circular, square,
