Abstract
The utility model relates to a can effectively improve LED printing opacity mirror of light efficiency utilization ratio. Including frustum and the ring of lower part on upper portion, frustum and ring are PMMA substrate structure, and this frustum and ring are even as an organic whole, and the upper end of this frustum is a cylinder recess, and the lower extreme has a bellied sphere downwards, and the lateral wall distributes and has the spherical piece, the area of spherical piece equals on same horizontal ring, and the area from the bottom up of this spherical piece subtracts progressively. The LED light source is refracted through the cylindrical groove at the upper end of the frustum and reflected through the spherical blocks distributed on the outer side wall of the frustum and finally refracted out from the lower end of the frustum, so that the light utilization rate is greatly improved, and the uniformity of output light is still ensured.
Description
Technical field
The utility model relates to a kind of transmissive mirror, particularly a kind of LED transmissive mirror that can improve the light efficiency utilization rate greatly.
Background technology
LED is a competitive novel solid light source of 21 century, it have the efficient height, photochromic pure, energy consumption is low, the life-span is long, reliability and durability, pollution-free, control advantage such as flexible.Along with the LED technology is constantly perfect, the luminous flux of LED and light efficiency will improve constantly.The luminous flux of single white light LEDs has reached more than the 200lm at present.The illuminator that with LED is light source is on the increase.The bright dipping of led chip is that Lambertian distributes, such optical field distribution, if handle and directly use without suitable optical system, in most of the cases all be difficult to satisfy lighting and during the required performance indications that reach.Therefore, to being that to carry out the secondary optics design be ishifenbiyaode for the illuminator of light source with LED.Illuminator realizes that even illumination then is to make illuminator in a given zone, form the uniform hot spot of illumination through the secondary optics design.Illuminator generally is divided into reflection-type, refractive and reflected refraction mixed type, and wherein reflected refraction mixed type is mainly utilized total internal reflection (TIR) technology.It is big that LED goes out optical range, and reflection-type or refractive illuminator often are difficult to whole bright dippings of control LED, and TIR utilizes refraction and total reflection, can the large-scale bright dipping of effective collection LED, and the control beam distribution, guarantee that lighting system structure is compact., the efficient of existing optical system processing can only reach 91.8% at most.
The utility model content
The utility model provides a kind of LED transmissive mirror that can improve the light efficiency utilization rate greatly to the deficiency of prior art.
The utility model is realized through following technical scheme:
A kind of LED transmissive mirror comprises the frustum on top and the annulus of bottom, and said frustum and annulus are the PMMA matrix structure; This frustum and annulus are connected as a single entity; The upper end of this frustum is a cylinder groove, and there is a sphere to lower convexity the lower end, and outer wall has the sphere piece; The area of said sphere piece equates that on same horizontal loops the area of this sphere piece successively decreases from top to bottom.
The beneficial effect of the utility model is: led light source reflects from the lower end of frustum through the sphere piece reflection of frustum outer wall through the cylinder groove refraction of frustum upper end more at last; Not only improve the utilization rate of light greatly, also still guaranteed the output uniformity of light.

Fig. 2 is the vertical view of the utility model.
Wherein, Reference numeral
1---frustum
2---annulus
3---the cylinder groove
4---sphere
5---the sphere piece
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail, but not as the qualification to the utility model.
Can find out that from Fig. 1 and Fig. 2 the utility model comprises the frustum 1 on top and the annulus 2 of bottom, said frustum 1 is the PMMA matrix structure with annulus 2; This frustum 1 is connected as a single entity with annulus 2; The upper end of this frustum 1 is a cylinder groove 3, and there is a sphere 4 to lower convexity the lower end, and outer wall has sphere piece 5; The area of said sphere piece 5 equates that on same horizontal loops the area of this sphere piece 5 successively decreases from top to bottom.
Led light source reflects from the lower end of frustum 1 through sphere piece 5 reflections of frustum 1 outer wall through cylinder groove 3 refractions of frustum 1 upper end more at last, has not only improved the utilization rate of light greatly, has also still guaranteed the output uniformity of light.
Below the utility model is done a detailed description, but obvious, those skilled in the art can carry out various changes and improvement, and the scope of the utility model that does not deviate from appended claims and limited.
