The mode not only low production efficiency of person's spraying, but also made by a dispensing or spraying, fluorescent powder and silica gel global formation
It is bad, in addition, the chip of existing emitting semiconductor structure is directly as in fixed substrate, there is no any protection structure, this
Sample emitting semiconductor structure is easily damaged.
Invention content
In order to overcome the problems referred above, the purpose of this utility model is to provide a kind of emitting semiconductor knot that can send out a variety of coloured light
Structure, fluorescent film global formation is good, allows emitting semiconductor uniform in light emission, and can send out a variety of coloured light.
The utility model is realized using following scheme：A kind of emitting semiconductor structure that can send out a variety of coloured light, including it is solid
Determine substrate and transparent protective shield, at least four luminous semiconductor chips, four emitting semiconductor cores are set in the fixed substrate
There are four the fluorescent film of different colours, the fluorescent film squarely cover body structures of four different colours to be covered with fluorescence on piece cover
The luminous semiconductor chip of film is bonded in the fixed substrate, and luminous semiconductor chip is evenly distributed in fixed substrate,
Multiple groove bodies, the quantity phase of the quantity of the groove body and the luminous semiconductor chip are offered below the transparent protective shield
Together, the transparent protective shield covers in fixed substrate, and luminous semiconductor chip can be located in the groove body.
Further, the transparent protective shield is organic silica gel cover body or inorganic silica gel cover body.
Further, the fluorescent film is made of fluorescent powder and silica gel.
Further, the fluorescent film of the different colours be respectively yellow fluorescence film, red fluorescence film, green fluorescent membrane with
And blue-fluorescence film.
The beneficial effects of the utility model are：The utility model uses the fluorescent powder and silica gel of different colours, is fabricated to
Fluorescent film；By heating and vacuum, so that the fluorescent film of different colours is attached to single luminous semiconductor chip, it need not be carried out
His technique or operating type operation, effectively reduce difficulty of processing and making, attach the luminous of different colours film by lighting and partly lead
Body chip can send out the light of different colours, and it is not that traditional a dispensing or spraying are made that fluorescent film, which is global formation,
Industry is molded, and can allow emitting semiconductor structure uniform in light emission in this way, consistency（Concentration degree）More preferably.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Refering to Figure 1, the utility model provides a kind of emitting semiconductor structure that can send out a variety of coloured light, including
Fixed substrate 1 and transparent protective shield 2, are arranged at least four luminous semiconductor chips 3 in the fixed substrate 1, and four shine half
3 upper cover of conductor chip there are four different colours fluorescent film 4, the 4 squarely cover body structure of fluorescent film of four different colours,
The luminous semiconductor chip 3 for being covered with fluorescent film 4 is bonded in the fixed substrate 1, and luminous semiconductor chip 3 is evenly distributed on
In fixed substrate 1, the fluorescent film 4 of such different colours covers on different luminous semiconductor chips, and overall structure can realize hair
Go out a variety of coloured light.2 lower section of the transparent protective shield offers multiple groove bodies 21, and the quantity of the groove body 21 shines partly with described
The quantity of conductor chip 3 is identical, and the transparent protective shield 2 covers in fixed substrate 1, and luminous semiconductor chip 3 can be located at institute
It states in groove body 21.The transparent protective shield 2 enables luminous semiconductor chip 3 to be more securely arranged in fixed substrate 1, in this way
Damage is not fallen out after luminous semiconductor chip is touched；In the utility model, the transparent protective shield 2 is organic silica gel cover body
Or inorganic silica gel cover body.The fluorescent film 4 is made of fluorescent powder and silica gel.And it is not traditional one that fluorescent film, which is global formation,
Dispensing or spraying operation molding, can allow emitting semiconductor structure uniform in light emission in this way, consistency（Concentration degree）More preferably.
In addition, in the present invention, the fluorescent film 4 of the different colours is respectively yellow fluorescence film 41, red fluorescence
Film 42, green fluorescent membrane 43 and blue-fluorescence film 44.It can also be the fluorescent film of other multiple colors in practical application.
In short, the utility model uses the fluorescent powder and silica gel of different colours, it is fabricated to fluorescent film；By heating and very
Sky makes the fluorescent film of different colours be attached to single luminous semiconductor chip, need not carry out other techniques or operating type is made
Industry effectively reduces difficulty of processing and making, and the luminous semiconductor chip of different colours film is attached by lighting, can send out difference
The light of color, and it is not traditional dispensing or spraying operation molding that fluorescent film, which is global formation, can allow hair in this way
Photosemiconductor structure uniform in light emission, consistency（Concentration degree）More preferably.
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.
