Abstract

The utility model discloses a three primary color device matched with an OLED for an LED. The three primary color device primarily comprises a support, red LED chips, blue LED chips, a green OLED, an adhesive, bonding lines, and a rubber encapsulation body. During the manufacturing process of the utility model, the red LED chips, the blue LED chips and the green OLED are arranged on the support; after down-leads are bonded, the red LED chips, the blue LED chips, the green OLED are encapsulated with the rubber encapsulation body. The three primary color device matched with the OLED effectively makes use of the high luminous efficiency of the green OLED, and is combined with the red LEDs and the blue LEDs, thus forming the three primary color device matched with the OLED with high luminous efficiency and light mixing effect. The three primary color device can be widely used for various illuminance products.

Description

The three primary colours device that LED matches with OLED

Technical field

The utility model patent relates to illuminating product, the white light parts that a kind of LED three-color light-emitting produces, particularly relate to a kind of, the three primary colours device that 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 illuminating devices arise at the historic moment.The three primary colours device is used widely at present, 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 large-scale LCD is 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 the green device portions luminous efficiency of traditional three-primary color LED is low, greatly limited making full use of of red, blue led chip light emitting efficient, only improved the brightness of devices at present to improve aspects such as R, G, B three-primary color LED chip light-emitting efficiency.

The utility model content:

The three primary colours device that the purpose of this utility model is to provide a kind of mixed light is effective, luminous efficiency is high LED to match with OLED.

The utility model is to realize above-mentioned purpose by following technical solution: the three primary colours device that LED of the present utility model matches with OLED, chief component comprises support, red LED chips, blue led chip, green device, bonding line, packing colloid, red LED chips, blue led chip, green device 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 device is green OLED, red LED chips, blue led chip, green OLED are placed on the same support, and luminescence chip of all kinds is connected in parallel and is one.

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.

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 the three primary colours device that LED of the present utility model matches with OLED can reach is, by adopting green OLED to replace green LED, the luminous efficiency of the three primary colours device 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 three primary colours device that the LED of even light mixing matches with OLED by different layout type.
