Abstract
The invention relates to an LED device with a reflection face capable of active deformation. The reflection face is made of a thermal bimetallic strip, in the heating process, both an active layer and a passive layer of the thermal bimetallic strip will be expanded after being heated, the thermal expansion coefficient of the active layer is larger than the thermal expansion coefficient of the passive layer, and therefore the elongation of the active layer is larger than the elongation of the passive layer. Thus, in the heating process, the thermal bimetallic strip will deform, the deformation degree can be achieved by controlling the heating power of a heating piece tightly attached to the reflection face, and therefore the dynamic control over the shape of the reflection face can be achieved. According to the technical scheme, the LED device has the advantages of being simple in structure and capable of being controlled with large freedom degree, and making the reflection face achieve miniature deformation, and therefore different optical focusing effects can be achieved.
Description
Technical field
The present invention relates to a kind of LED matrix with reflecting surface that can active deformation, belong to lighting technical field.
Background technology
At present, in the LED illuminating engineering, the reflecting surface usually adopted is solid shape, can not change along with needs the shape of reflecting surface.
Summary of the invention
Patent of the present invention is improved the reflecting surface of traditional solid shape, and the new LED matrix with reflecting surface that can active deformation can initiatively controllably change the shape of reflecting surface.
In order to reach the foregoing invention purpose, the technical solution adopted in the present invention is.
A kind of LED matrix with reflecting surface that can active deformation, be comprised of reflecting surface and LED, and the material of reflecting surface comprises thrermostatic bimetal-plate, and reflecting surface has at least one perforation, and LED is housed in perforation, and fever tablet is posted on the reflecting surface surface.
Better, above-mentioned fever tablet is array-like and is close to the reflecting surface surface.
Better, above-mentioned fever tablet connects power supply, by controlling the output power of power supply, controls the temperature on fever tablet surface, and then controls the curvature of reflecting surface part.
Know-why of the present invention is to realize like this, the material of reflecting surface adopts thrermostatic bimetal-plate, in heating process, active layers in thrermostatic bimetal-plate and passive layer all can expanded by heating, but the thermal coefficient of expansion of active layers is greater than the thermal coefficient of expansion of passive layer, the elongation of active layers will be greater than the elongation of passive layer like this, therefore, in heating, thermo bimetal's sector-meeting generation deformation, the heating power that the size of deformation can be close to the heating plate of reflecting surface by control is realized, and then has been realized the dynamic control to reflector shape.
Compared with prior art, technical scheme provided by the invention has characteristics simple in structure, controls and gets up to have the very large free degree, makes reflecting surface realize small deformation, and then obtains different optical focus effects.
