Specific embodiment

With reference to the accompanying drawings and examples this utility model is described in detail.

Embodiment 1

As shown in figure 1, a kind of LED 1, including housing 11, blue-ray LED luminescent wafer 12 and light conversion layer；The housing 11 Upper to arrange fluted, the blue-ray LED luminescent wafer 12 is arranged in the groove of the housing 11, and the light conversion layer is filled in In the groove of the housing 11, the light conversion layer is quantum dot-fluorescent material light-converting material.

The quantum dot-fluorescent material light material of walking around is mixed with transparent solvent 15 by yellow fluorescent material 13, quanta point material 14 Formed.

In prior art, some blue light sent by blue-ray LED luminescent wafer excites yellow fluorescent material to send gold-tinted, blue light White light is mixed to form with gold-tinted；The advantage of yellow fluorescent material is that its light conversion ratio is high, i.e., send in the blue-ray LED luminescent wafer Blue light light intensity identical in the case of, using yellow fluorescent material use as light-converting material ratio quanta point material as light change Material, the brightness of the white light that LED finally sends are higher；But advantage of the quanta point material as light-converting material is white light Chromatic threshold value and color saturation are higher, therefore, the LED 1 of the technical program mixes quantum dot material in existing yellow fluorescent material 13 Material 14, in the case where white light high brightness is kept, effectively increases the color gamut value and color saturation of white light.

The blue-ray LED luminescent wafer 12 in LED 1 shown in Fig. 1 is also associated with two metal lines 16, the company of being respectively used to The both positive and negative polarity of power supply is connect, it should be strongly noted that certain form of LED luminescent wafers need not connect metal wire or only have One metal line, therefore, the protection domain of the technical program should not be limited only to the present embodiment and Fig. 1, luminous using any LED Chip all should be in protection domain.

The quanta point material 14 includes red quanta point material 14 or/and green quanta point material 14, the blue LED wafers Issued section blue light excites the red quanta point material 14 or/and green quanta point material 14 sends HONGGUANG or/and green glow, improves institute The purity and energy of HONGGUANG or/and green glow in the white light that LED 1 finally sends are stated, is satisfied with reaching the chromatic threshold value and color that improve white light With the purpose of degree, certainly, the quanta point material 14 can also include blue quanta point material 14.

The transparent solvent 15 is silica gel or epoxy resin or UV glue, or other transparent polymer materials.
