Description

White light parts and manufacture method
Technical field
Patent of the present invention relates to illuminating product, and the white light parts of the luminous generation of a kind of LED particularly relates to white light parts and manufacture method that a kind of luminous efficiency height, the effective LED of mixed light match with OLED.
Background technology
LED is the abbreviation LED of Light Emitting Diode light emitting diode; OLED is the abbreviation OLED of Organic Light-Emitting Diodes Organic Light Emitting Diode; Along with the continuous development of lighting engineering, range of application constantly enlarges, and all kinds of lighting sources arise at the historic moment.At present white light parts is used widely, and as applications such as fluorescent lamp, colorful display screen, lighting engineerings, and three-primary color LED also is widely used in fields such as the indoor display screen of LED, large-scale LCD are backlight, brightening illumination with its Color Range advantage.Fig. 1 is traditional three-primary color LED groundwork circuit theory schematic diagram, its three-primary color LED is redness, blueness and green LED, because traditional three-primary color LED green light source part luminous efficiency is low, greatly limited making full use of of red, blue led chip light emitting efficient, only improve the brightness of device at present to improve aspects such as R, G, B three-primary color LED chip light-emitting efficiency, also do not have a kind of research to adopt the mode of novel light-emitting chip to improve the white light parts performance, nobody attempts adopting OLED and mode red, that blue coupling forms white light.
Summary of the invention:
The object of the present invention is to provide a kind of mixed light is effective, luminous efficiency is high white light parts and manufacture method.
The present invention realizes above-mentioned purpose by following technical solution: a kind of white light parts manufacture method of the present invention, it is characterized in that, it is to adopt the common luminous mixing of red LED, blue led and green OLED to produce the mode of white light, by adhesive red LED chips, blue led chip and green OLED chip are arranged on the same support earlier, then by the conductive pin on bonding line tube connector core electrode and the above-mentioned support, by packing colloid said chip is encapsulated again and get final product.
White light parts of the present invention, its part comprises support, red LED chips, blue led chip, green light source, bonding line, packing colloid, red LED chips, blue led chip, green light source are arranged on the support by adhesive, packing colloid, conductive pin on bonding line tube connector core electrode and the above-mentioned support, packing colloid encapsulates said chip; It is characterized in that described green light source is green OLED, red LED chips, blue led chip, green OLED are placed on the same support.
As further specifying of such scheme, described red LED chips, blue led chip, green OLED are " one " word arrangement or " product " word arrangement or sphere of movements for the elephants arrangement collocation.In above-mentioned alignment processes, described green OLED arrange regional is greater than the arrange regional of red LED chips and blue led chip composition; The quantity of described red LED chips, blue led chip, green OLED is 1～N.
This support can also be to have the emission cavity that mixed light is used, reflection cavity be shaped as rectangle, square, circle or oval.
This support can also be to be a planar structure.
Packing colloid is transparent or for chromatic dispersion is arranged.
The effect that white light parts of the present invention can reach is, by adopting green OLED to replace green LED, the luminous efficiency of the white light parts green portion that raising LED matches with OLED, make full use of the high-luminous-efficiency of red LED chips, blue led chip, form the white light parts that the LED of even light mixing matches with OLED by different layout type.
