Abstract
The utility model relates to a reflecting mirror, which comprises an LED luminous body and a reflecting mirror body, wherein the reflecting mirror body adopts a reflecting type mirror surface, and the reflecting surface of the reflecting type mirror surface is an analog parabolic cambered surface, and one or a plurality of LED luminous bodies are relatively arranged on the just upper portion of the reflecting surface. Compared with a traditional transmission type reflecting mirror, the utility model can obtain a directrix parallel light beam with smaller longitudinal divergence angle, as a taper light beam which is send out from the LED luminous body can form a rectangular view field one the front end after being reflected by the reflecting surface, an analog parabolic cambered surface reflecting mirror can well match with the LED luminous body, and has no loss after being reflected, has even illumination distribution as a horizontal view field is changed into a rectangular, thereby realizing the purpose of amplifying transverse horizontal view angle, and increases the luminous effect and illumination as an original round view field is changed into a rectangular view field, which is a highly effective optical accessory. The utility model not only can be used on a warning lamp, but also can be used on other analog spotlight lighting devices.
Description
Technical field
The utility model relates to a kind of optical accessories, relates in particular to a kind of reflective mirror.
Background technology
Tradition LED illuminator is used the optics that needs various lens to do 1～2 time and is dispersed processing on warning lamp, with increase visual angle and visual field, the big high attenuation of this through mode optical treatment illuminance.
Summary of the invention
The purpose of this utility model is at not enough defective of the prior art, and a kind of simple in structure, reflective mirror that illuminance is strong is provided.
For achieving the above object, the utility model adopts a kind of reflective mirror, comprises LED illuminator, reflective mirror body, and the reflective mirror body adopts reflective minute surface, the reflective surface of reflective minute surface is a class parabolic cambered surface, one or more LED illuminators are corresponding be located at reflective surface directly over.
Reflective minute surface of the present utility model has two kinds of structures, and its cross section can be the Off type, also can for
Type.
The utility model adopts reflective minute surface, compare with traditional through mode, after reflecting by reflective surface, the cone-shaped beam that sends to form the visual field of rectangle at front end from the LED illuminator, class parabolic cambered surface reflective mirror is the cone-shaped beam of cooperated with LED illuminator well, can obtain the less quasi-parallel light beam in a branch of longitudinal divergence angle, and almost lossless after the reflection; Transverse field is transformed into rectangle, Illumination Distribution is even, reached the purpose of only amplifying the transverse horizontal visual angle, changing former circular visual field simultaneously is rectangular field, light efficiency and illumination have been increased substantially, be optical accessories very efficiently, the utility model not only can be used on the warning lamp, also can be used on other similar spotlighting equipment.
Description of drawings
Fig. 1 is the utility model embodiment front schematic view.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, specific embodiment of the utility model is a kind of reflective mirror, comprise LED illuminator 1 and printed board assembly 2, reflective minute surface 3, the cross section of reflective minute surface 3 is the Off type, the reflective surface 31 of reflective minute surface 3 is a class parabolic cambered surface, irradiation mouth 32 shapes of reflective minute surface 3 are rectangular, a plurality of LED illuminators 1 be listed as into one row be located at reflective surface 31 directly over, the reflective surface 31 of the just in time corresponding reflective minute surface 3 in the position of LED illuminator 1, the light beam that penetrates from LED illuminator 1 penetrates through the secondary reflection of reflective mirror.
The cross section of the reflective minute surface 3 in the foregoing description is the Off type, and irradiation mouthful 32 shapes are rectangular, and this is a kind of frame mode,, also can make other shapes, also can be such as the cross section of reflective minute surface 3
Type, as long as the reflective surface 31 of reflective minute surface 3 is a class parabolic cambered surface, and the light that sends of LED illuminator 1 can get final product in the visual field that front end forms rectangle after reflection.
The utility model is compared with traditional through mode, after the cone-shaped beam that sends from LED illuminator 1 reflects by reflective surface 31 Can form at front end the visual field of rectangle, class parabolic cambered surface reflective mirror is the taper light source of cooperated with LED illuminator well, can Obtain the littler quasi-parallel light beam in a branch of longitudinal divergence angle, and almost lossless after the reflection; Transverse field is transformed into rectangle, shines Degree is evenly distributed, and has reached the purpose of only amplifying the transverse horizontal visual angle, and changing simultaneously former circular visual field is rectangular field, significantly Having improved light efficiency and illumination, is very efficient optical accessories, and the utility model not only can be used on the warning lamp, also can be used on other Similarly on the spotlighting equipment.
Claims (3)
