It doubts and increases manufacturing cost.
Invention content
In order to overcome the problems referred above, the purpose of this utility model is to provide sends out shining for a variety of coloured light based on chip realization
Semiconductor can launch the light of multiple color by a chip, reduce production cost.
The utility model is realized using following scheme：It is a kind of to realize that sending out the luminous of a variety of coloured light partly leads based on a chip
Body includes the luminous semiconductor chip of an areflexia cover board, a fluorescent film, the fluorescence is covered on the luminous semiconductor chip
Film squarely cover body structure, the surface at the top of the fluorescent film, which divides, multiple regions, and the fluorescent film correspondence in each region is set
It is equipped with a kind of color, one first reflecting layer is provided at the top of the fluorescent film, four sides are all provided with around the fluorescent film
It is equipped with one second reflecting layer, the multiple region is four regions, and four regions etc. are big is uniformly distributed.
Further, the fluorescent film is made of fluorescent powder and silica gel.
Further, the fluorescent film in four regions is correspondingly arranged there are four types of color, and four kinds of colors are respectively：In vain
Color, red, green and yellow.
Further, the region is homalographic region.
The beneficial effects of the utility model are：The fluorescent film global formation of the utility model is good, can allow shine and partly lead
Body uniform in light emission, and by the effect in the first reflecting layer and the second reflecting layer, the luminous energy that such luminous semiconductor chip is sent out to
Surrounding dissipates, and such illumination effect is good, and fluorescent film division is had multiple regions, the fluorescent film in each region by the utility model
It is correspondingly arranged on a kind of color, as long as a luminous semiconductor chip can send out the light of multiple color in this way.
Description of the drawings
Fig. 1 is the structural schematic diagram that the first reflecting layer and the second reflecting layer are not arranged for the utility model.
Fig. 2 is the sectional view of the utility model.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
It please refers to Fig.1 with shown in Fig. 2, the utility model provides a kind of hair realized based on a chip and send out a variety of coloured light
Photosemiconductor includes the luminous semiconductor chip 1 of an areflexia cover board, a fluorescent film is covered on the luminous semiconductor chip 1
2,2 squarely cover body structure of the fluorescent film, the surface at 2 top of the fluorescent film, which divides, multiple regions 3, each region 3
Fluorescent film 2 be correspondingly arranged on a kind of color, the top of the fluorescent film 2 is provided with one first reflecting layer 4（Reflecting layer can adopt
With transmitting cover board）, four sides are both provided with one second reflecting layer 5, such luminous semiconductor chip around the fluorescent film 2
1 adjusts light emitting angle through the first reflecting layer 4 and four the second reflecting layer 5 of surrounding, reaches and dissipates around, sends out in this way
Light effect is good；The multiple region 3 is four regions, and four regions etc. are big is uniformly distributed.The fluorescent film 2 is by fluorescence
Powder and silica gel are made.
In the utility model, the fluorescent film 2 in four regions 3 is correspondingly arranged there are four types of color, and four kinds of colors are divided
It is not：White, red, green and yellow.There are multiple regions, the fluorescent film correspondence in each region to set fluorescent film division
It is equipped with a kind of color, as long as a luminous semiconductor chip can send out the light of multiple color in this way.Preferably, those regions can
To be homalographic region, those regions can be fan-shaped, heart-shaped or various regular patterns.
In short, the fluorescent film global formation of the utility model is good, emitting semiconductor uniform in light emission can be allowed, and pass through first
The effect in reflecting layer and the second reflecting layer, the luminous energy that such luminous semiconductor chip is sent out dissipate around, such illumination effect
It is good, and fluorescent film division is had multiple regions, the fluorescent film in each region to be correspondingly arranged on a kind of color by the utility model, this
As long as one luminous semiconductor chip of sample can send out the light of multiple color.
Although it is noted that the utility model integrally look over it is simple in structure, its structure no matter from make work
Skill, or it is all very prominent from using effect：
1. fluorescent film is by fluorescent powder and silica gel（Containing silicone resin）Composition forms fluorescent film by knifing machine knifing and heating；
2. after fluorescent film completes, may be produced that different shape or sized membrane by cutting, being attached to emitting semiconductor
（Or do not cut direct attaching）；
3. attaching emitting semiconductor by fluorescent film, emitting semiconductor uniform in light emission can be allowed, consistency（Concentration degree）More
It is good；
4. fluorescent film is attached than traditional dot fluorescent powder（Glue）On emitting semiconductor and coating（Containing outer cover）It light extraction and can grasp
The property made is strong, and precision is more preferable；
5. fluorescent film is attached to emitting semiconductor, attached by heat and vacuum, does not increase glue or other substances are viscous
Patch, and fluorescent film is applied to emitting semiconductor and improves heat conductivity.
The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the claims it is equal
Deng variation and modification, it should all belong to the covering scope of the utility model.
