Abstract
A kind of paster LED with optically focused stent, it includes LED flip chip and resin film, and LED flip chip is fixed on stent；On stent, there is reflector outside LED flip chip, reflector inner wall is reflective surface.The advantageous effect that paster LED of the utility model with optically focused stent is reached：Simple in structure, light-emitting angle facilitates controllably at 30 °~100 ° and carries out Lighting Design and application, and can form required spectrum.
Description
Technical field
The utility model is related to a kind of lighting device, particularly a kind of paster LED.
Background technology
Existing surface-mounted LED light source, LED chip are located in stent, the filling with sealant water in the recess of stent, because
It is liquid for glue so that light-emitting surface is all flat, and above structure paster LED has the following disadvantages：
1st, optical design is not done, and beam angle out is all 120 ° or so, and Lambertian distribution is presented；
2nd, the wide-angle of surface-mounted LED light source match light output, generally cannot directly as the light extraction mode of our illuminators,
Need to add secondary optics device and carry out light beam integer, become the beam angle of low-angle, then could carry out Lighting Design and
Using.
In short, existing surface-mounted LED light source is needed after carrying out optical design, Lighting Design and application could be carried out.
Utility model content
The purpose of this utility model is just to provide a kind of paster LED with optically focused stent, it can directly export institute's light requirement
Beam, so as to more easily carry out Lighting Design and application.
The purpose of this utility model is that technical solution in this way is realized, it includes LED flip chip and resin is thin
Film, LED flip chip are fixed on stent；On stent, there is reflector outside LED flip chip, reflector inner wall is reflective song
Face.
In the utility model, the light of the monochromatic spectrum sent out in LED flip chip the directive after plexiglas is anti-
Its light of directive by the curved surface of optical design, can be reflected stent by light curved surface according to certain light-emitting angle.It is logical
Curvature, height, opening size of adjustment reflective surface 5 etc. is crossed, the range of the light-emitting angle of LED light source can be 30 °~100 °.
By adopting the above-described technical solution, the utility model has the following advantages：Simple in structure, light-emitting angle is controllable
At 30 °~100 °, facilitate and carry out Lighting Design and application, and required spectrum can be formed.
Description of the drawings
The description of the drawings of the utility model is as follows：
Fig. 1 is a kind of diagrammatic cross-section of the utility model；
In figure：1.LED flip-chips；2. resin film；3. stent；4. reflector；5. reflective surface.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figure 1, the utility model includes LED flip chip 1 and resin film 2, LED flip chip 1 is fixed on branch
On frame 3；On stent 3, there is reflector 4 outside LED flip chip 1,4 inner wall of reflector is reflective surface 5.
In the utility model, the light of the monochromatic spectrum sent out in LED flip chip 1 the directive after resin film 2
Its light of directive by the curved surface of optical design, can be reflected reflector by reflective surface according to certain light-emitting angle
4.Curvature, height, opening size by adjusting reflective surface 5 etc., the range of the light-emitting angle of LED light source can be 30 °~
100°。
Further, LED flip chip 1 can be monochrome blue chip or ultraviolet chip, can also be red
Chip can also be Green Chip, can also be yellow chip, the fluorescent powder of different chip binding resin films 2 filling can
To form required spectrum.Such as white-light spectrum is formed, can be that LED flip chip 1 uses blue chip or ultraviolet chip,
Can white-light spectrum uniformly be generated filled with red, yellow fluorescent powder or red, green, blue fluorescent powder in resin film 2, it can also
It is ultraviolet excitation redgreenblue fluorescent powder, forms the spectrum of recombined white light；Such as monochromatic spectrum is formed, can be upside-down mounting
LED chip is directly using red, green, yellow etc., and resin film is transparent, without fluorescent powder.
Further, reflector 4 is the reflecting rate height of epoxy resin or silicones, epoxy resin and silicones,
Light can more be fully utilized in this way so that the loss of light is small, so as to improve the utilization rate of light.
