Background technology:
Making at present one of method of white light LEDs, is to apply fluorescent material in the blue-light LED chip outside.Concrete technique is after the blue light led chip of radiative wavelength main peak in 450～470nm scope welded, at its surface-coated rare-earth yttrium-aluminium garnet (YAG) series phosphor powder.This fluorescent material can the emission gold-tinted under blue ray radiation, and the gold-tinted complementation that the blue light that sends by chip sends after being activated with fluorescent material forms white light.
But there is the defective of a principle in this mode, because Ce in the fluorophor
3+The emission spectrum of ion does not have the continuous spectrum characteristic, and its color rendering is relatively poor, be difficult to satisfy the requirement of low colour temperature illumination, and its luminous efficiency is not high.
Summary of the invention:
For this reason, the purpose of this utility model is to provide a kind of individual particle paster mixed light LED module, sends the problem that the existing color rendering of white light is relatively poor, luminous efficiency is not high to solve the collocation of present blue-light LED chip and gold-tinted fluorescent material.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of individual particle paster mixed light LED module, comprise aluminum-based circuit board, be provided with a plurality of mixed light led chips and a plurality of red LED chips on the described aluminum-based circuit board, described mixed light led chip is made of sheet green emitting phosphor packaging body and the blue led chip that is encapsulated in this sheet green emitting phosphor packaging body.
Wherein said mixed light led chip is nine, and horizontal three vertical three evenly are arranged into rectangle; Described red LED chips is six, and in vertical or horizontal correspondence in twos between the adjacent mixed light led chip.
The spacing of wherein said red LED chips and adjacent mixed light led chip is between 1mm～3mm.
The power sum ratio of the power sum of wherein said mixed light led chip and red LED chips is 3:1.
The utility model is by forming the mixed light led chip at blue led chip encapsulation sheet green emitting phosphor packaging body, and correspondence is equipped with a red LED chip between adjacent mixed light led chip, the ruddiness that utilizes blue led the chip blue light that sends and the green glow that excites the green emitting phosphor packaging body to send and red LED chip to send carries out the compound white light that obtains.Compared with prior art, the utility model color rendering index can reach 90～97, has color rendering good, the advantage that luminous efficiency is high.
