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 with can the LED matrix of reflecting surface of active deformation, belong to lighting technical field.
Background technology
At present, in LED illumination engineering, the reflecting surface usually adopted is solid shape, can not along with needing the shape changing reflecting surface.
Summary of the invention
The reflecting surface of patent of the present invention to traditional solid shape improves, new for the LED matrix of reflecting surface of active deformation initiatively can controllably changing the shape of reflecting surface.
In order to reach foregoing invention object, the technical solution adopted in the present invention is.
A kind of with can the LED matrix of reflecting surface of active deformation, be made up of reflecting surface and LED, the material of reflecting surface comprises thrermostatic bimetal-plate, and reflecting surface has at least one to bore a hole, and in perforation, LED is housed, mirror surface posts fever tablet, fever tablet is that array-like is close to mirror surface, and fever tablet connects power supply, by controlling the output power of power supply, control the temperature on fever tablet surface, and then control the curvature of reflecting surface local.
Know-why of the present invention realizes 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 such active layers will be greater than the elongation of passive layer, therefore, when heating, thermo bimetal's sector-meeting generation deformation, the size of deformation can be realized by the heating power controlling to be close to the heating plate of reflecting surface, and then achieves the Dynamic controlling to reflector shape.
Compared with prior art, technical scheme provided by the invention has the simple feature of structure, controls to get up to have the very large free degree, makes reflecting surface realize small deformation, and then obtains different optical focus effects.

Detailed description of the invention
Understand for the ease of those of ordinary skill in the art and implement the present invention, below in conjunction with the drawings and the specific embodiments, the present invention is described in further detail.
Fig. 1 is the schematic cross-section of reflecting surface at non-deformation state of embodiments of the invention 1 and 2.
embodiment 1
Structure of the present invention as shown in Figures 2 to 3, reflecting surface 1 is made up of mirror surface 4, active layers 5 and passive layer 6, mirror surface 4 is close to active layers 5, fever tablet 3 adds heat-reflecting surface 1, active layers 5 elongation is greater than passive layer 6, reflecting surface 1 becomes convex mirror by level crossing, and the light that LED2 sends becomes diverging light.
embodiment 2
Structure of the present invention as shown in Fig. 4 to Fig. 5, reflecting surface 1 is made up of mirror surface 4, active layers 5 and passive layer 6, mirror surface 4 is close to passive layer 6, fever tablet 3 adds heat-reflecting surface 1, active layers 5 elongation is greater than passive layer 6, reflecting surface 1 becomes concave mirror by level crossing, and the light that LED2 sends becomes converged light.
The above, only that specific embodiment of the invention case is described, and be not used to limit of the present invention can practical range, such as all equivalences that those skilled in the art complete under the spirit do not departed from indicated by the present invention and principle change or modify, and must be covered by the scope of the claims in the present invention.
