Description
Technical field
The present invention relates to Reflectron technology field, more particularly to the low-angle reflector of a kind of achievable higher order reflection and its
Using.
Background technology
The original angular of LED point light source is 120 degree, and reflector is to change similar to a kind of concentrator, the effect of reflecting curved surface
Become the light direction of propagation, after so that the light of big Mr. Yu's angle is incident upon thereon, can exiting parallel, to efficiently use luminous energy.Root
According to required calculating reflecting curved surface radian, exiting parallel after making the light being emitted on reflector reflect, so adding after point light source
After a upper reflector, the light of dispersion can be gathered within the scope of one originally, and the light of small Mr. Yu's angle could not be mapped to
Directly being emitted on reflector leads to one blackening of intermediate appearance.
Long drive type reflector currently on the market is mostly parabolic shape reflector, and long drive distance is more than certain distance
Afterwards, center will appear blackening, and as distance increases, the effect caused by blackening will be amplified, and can have been seriously affected long drive and regarded
Feel effect, thus also cannot be satisfied the requirement of long drive lamps and lanterns.If reflector is in order to reflect angular range big as possible simultaneously
Light, the angle of reflecting curved surface need as possible small, and length requirement also increases, therefore traditional reflector can no longer meet and work as
Pursuit of modern epoch to slimming.
Invention content
It is an object of the invention to overcome the deficiencies of existing technologies and insufficient, a kind of the small of achievable higher order reflection is provided

Between multiple reflections, make the light of the low-angle multiple reflections in the inner step of reflector, effectively improve reflector and produced
The bad problem of raw Center Dark Spot and uniform light degree, while it is lightening so that glow cup is realized.
Another object of the present invention is to provide a kind of LED equipped with the low-angle reflector that higher order reflection can be achieved
Lamp.
The purpose of the present invention can be achieved through the following technical solutions：A kind of low-angle reflection of achievable higher order reflection
Device, the reflector are bowl structure, and outside wall surface is conduction reflecting layer, is internally provided with multistage ladder, the axis of the reflector
Hole is provided at line.
The conduction reflecting layer is circular arc camber or S-shaped curved surface as a preferred technical solution,.

The reflectivity of light.
The reflective layer is made of polymethyl methacrylate as a preferred technical solution,.Polymethyl methacrylate
(PMMA) be high reflectance material, it is possible to reduce the loss of light.
The reflective layer is printed on the conduction reflecting layer and rank by silk-screen printing technique as a preferred technical solution,
On ladder.
As a preferred technical solution, along reflector bottom to the central axes direction of opening, the bottom surface of the annular stepped
Internal diameter increases step by step.
The annular stepped vertically declines or tilts and declines as a preferred technical solution,.Tilt the annular stepped declined
It can make the angle bigger of beam angle.
Another object of the present invention can be achieved through the following technical solutions：The small of higher order reflection can be achieved in a kind of be equipped with
The LED light of angle reflector, including LED light source, reflector and low-angle reflector, the low-angle reflector are placed in described anti-
Inside light cup, the low-angle reflector is overlapped with the central axes of the reflector, and the LED light source is placed in the reflector
At the central axes of bottom.
Compared with prior art, the present invention having the following advantages that and advantageous effect：
1, reflector is placed in inside reflector, keeps medium or wide-angle light more between reflector and conduction reflecting layer
Secondary reflection makes the light of the low-angle multiple reflections in the inner step of reflector, effectively improves caused by reflector
Center Dark Spot and the bad problem of uniform light degree.
2, to reflect the light of more perspective, the angle needs of reflector become smaller, and length needs are elongated, so that reflective
The volume of cup becomes larger.After reflector is added in reflector, the bigger that the angle of reflector can be done, or even close to plane, therefore
It may be implemented lightening.

Specific implementation mode
Present invention will now be described in further detail with reference to the embodiments and the accompanying drawings, but embodiments of the present invention are unlimited
In this.
As shown in Figure 1, 2, a kind of low-angle reflector of achievable higher order reflection, the reflector 1 are bowl structure, outside
Wall surface is conduction reflecting layer 2, is internally provided with multistage annular ladder 3, hole 4 is provided at the central axes of the bottom of the reflector.
Preferably, it conducts reflecting layer 2 and internal annular ladder 3 is equipped with reflective layer.Reflective layer can improve the reflection of light
Rate.Reflective layer is made of polymethyl methacrylate.Polymethyl methacrylate (PMMA) is the material of high reflectance, can be subtracted
The loss of few light.Reflective layer can be printed on by silk-screen printing technique on the conduction reflecting layer 2 and ladder 3.
As shown in figure 3, in another embodiment, internal annular ladder 3 is to tilt to decline.Along reflector bottom to opening
The central axes direction of mouth, the bottom surface internal diameter of annular stepped increase step by step.Under internal annular ladder 3 can be vertical decline or tilt
Drop.The angle bigger of beam angle can be made by tilting the annular stepped 3 declined.
As shown in Figure 4,5, the embodiments of the present invention also provide a kind of equipped with the low-angle reflection that higher order reflection can be achieved
The LED light of device, including LED light source 6, reflector 5 and low-angle reflector 1, the low-angle reflector 1 are placed in the reflector
Inside 5, low-angle reflector 1 is overlapped with the central axes of reflector 5, and LED light source 6 is placed at the central axes of the bottom of reflector 5.
As shown in fig. 6, conduction reflecting layer is circular arc camber or S-shaped curved surface.The material for conducting reflecting layer is plastics, can be passed through
The mode of injection molding processes to obtain.It is symmetrical according to symmetry axis 7 to conduct reflecting layer.
As shown in Figure 7,8, not plus the reflector of reflector, high angle scattered light that can be in reflex LED light source, and low-angle and
The light of middle angle is directly projected from intermediate, and without reflection, blackening is formed to be easy, causes the uniformity of light inadequate.
After reflector is added, medium or wide-angle the light of the LED light source multiple reflections between reflector and conduction reflecting layer, small angle
The light of degree enters reflector by aperture, the multiple reflections in the inner step of reflector, by the secondary light-distribution of reflector
Afterwards, LED light source can be increased by the light angle range of secondary light-distribution, the problem of so as to improve Center Dark Spot.
In conclusion the present invention utilizes higher order reflection principle, it is by conducting reflecting layer and inner step that light progress is more
Secondary reflection carries out secondary light-distribution, effectively improves the bad problem of Center Dark Spot, the uniform light degree of reflector.
