Description

A kind of RGBWWW mixed color LED encapsulating structure

Technical field

The utility model relates to LED technology fields, and in particular to a kind of RGBWWW mixed color LED encapsulating structure.

Background technique

With the continuous maturation in market, so that more and more requirements also proposed to lamp bead color and integration degree, The integration realization multiple color as far as possible on a bracket, comprising: the implementation of coloured light and white light, coloured light passes through feux rouges core Piece, green light chip, blue chip, and thus the chip of tri- kinds of colors of RGB is arranged in pairs or groups the coloured light etc. to be formed；The implementation of white light Mode that there are mainly two types of: first is that white light made of the chip hybrid for passing through tri- kinds of colors of RGB；Second is that passing through expandable stent bowl Cup, the chip placement in bowl, then encapsulated by fluorescent glue adaptation, such mode is only capable of obtaining solid color white light, mesh Preceding market only has full-color+a kind of color white light of RGBW() and full-color+two kinds of colors white light of RGBWW(), as depicted in figs. 1 and 2.

Existing bracket has the disadvantage in that

1, white light W color and aobvious finger are single: the bowl of expansion places LED chip, then encapsulates fluorescent glue, pass through fluorescence Powder excitation issues white light or solid color light.

2, the corresponding matching combination between color is less: the colour match combination of three primary colours (red, green, blue), hyperchromic It is known to us with complementary color.Same chip also excited by fluorescent glue generation different colours (it is possible that blue chip add it is glimmering Light powder inspires red, green, amber, yellow etc.), different-colour, difference is aobvious to be referred to, different CIE chromaticity coordinates etc., Ci Zhongxin The matched combined between light that piece excites fluorescent glue to generate in practical applications also very extensively can be with by such assembled scheme It is combined into us and wants photochromic, CIE color area coordinate points, show and refer to, color saturation etc., for example: the collocation of red and green color lamp bead can To be combined into 90 aobvious fingers:

Red lamp bead: with blue chip, red fluorescence powder and green emitting phosphor matched combined at fluorescent glue, then with glimmering Optical cement encapsulates blue chip, excites fluorescent glue to generate red lamp bead by blue chip, red lamp bead can be according to design requirement It is made into corresponding beche-de-mer without spike (CIE color area coordinate shows and refers to, brightness etc.) and color；

Green lamp bead: use blue chip, green emitting phosphor matched combined at fluorescent glue, then with fluorescent glue encapsulate blue light Chip excites fluorescent glue to generate green lamp bead by blue chip, and green lamp bead can be made into corresponding beche-de-mer without spike according to design requirement (CIE color area coordinate shows and refers to, brightness etc.) and color；

Finally, red lamp bead and green lamp bead are mounted on same substrate again, it is spaced spacing appropriate, red lamp bead The green light that the feux rouges of sending and green lamp bead issue, can be overlapped mutually the white light for being combined into that aobvious finger is 90.

Example are as follows: red green collocation will do the white light of 2700K CRI90: red lamp bead (1000-1300K CRI46 or so), Green lamp bead (4500-5500K CRI61 or so), two kinds of lamp beads are mounted on same substrate, can be combined into colour temperature 2700K The white light of left and right CRI90.

Thus it will be seen that the color of lamp bead combines (two different-colours, different CIE coordinates, aobvious finger of difference etc.), It can be combined into another new color, no matter the new color after combination is in colour temperature, CIE coordinate, showing finger etc. can change.It can It is further contemplated that three different colours or more different colours, if the permutation and combination that can arrange in pairs or groups, can be at more colors Expand out bigger colour gamut.

3, integration degree is short of: realizing above-mentioned described more colors, bigger colour gamut, it is obviously desirable to more colors It is integrated.
