The specific embodiment
The light fixture of a kind of convertible beam shape provided by the invention; Comprise light emitting source, reflector, thermal insulation board, liquid-crystal controller, liquid crystal device and lens and lens carrier; Further; Light fixture is included in a reflector of its rear end setting and is arranged at the light emitting source of inner surface for perifocus place in the reflector of type paraboloid structure; Semicircle thermal insulation board is arranged at the front end of this reflector and has a liquid crystal device to be arranged at the front end of this thermal insulation board, and a liquid-crystal controller links to each other with liquid crystal device through soft base circuit board, and the light fixture front end is provided with a lens carrier and lens; Through the control mode of adjustment light beam, can realize that complicated field of illumination reaches the purpose of the intelligent control in field of illumination.For making the object of the invention, technical scheme and advantage clearer, the embodiment that develops simultaneously with reference to the accompanying drawings is to further explain of the present invention.
Along with the fast development of lighting engineering, during the light source of a large amount of high-performance high brightness has been applied to practical project and has lived, the function that under various varying environments, plays illumination or decorate.Particularly automobile industry is to light control with prevent the requirement of light pollution increasingly stringent, and intelligent lighting engineering more and more highlights the urgency of its importance and development.Present constraint of lamp lighting beam shape and control can not be satisfied the demand far away.The mode of intelligence transformation beam shape progressively becomes following Vehicular intelligent illumination trend.A kind of mode and structure of novel control light fixture beam shape through the Beam Control mode of the embodiment of the invention, can realize complicated field of illumination, thereby be to realize further that the field of illumination is intelligent to control.
The embodiment of the invention provides a kind of light fixture of convertible beam shape, and is as shown in Figure 5, comprises light emitting source 3-7, reflector 3-6, thermal insulation board 3-5, liquid-crystal controller 3-4, liquid crystal device 3-3 and lens 3-1 and lens carrier 3-2.A kind of light fixture of variable beam comprises; A reflector that is provided with in its back-end and a light emitting source that is arranged at perifocus place in the reflector that inner surface is a type paraboloid structure; Semicircle thermal insulation board is arranged at the front end of this reflector and has a liquid crystal device to be arranged at the front end of this thermal insulation board; One liquid-crystal controller links to each other with liquid crystal device through soft base circuit board, and the light fixture front end is provided with a lens carrier and lens.
Particularly, in embodiments of the present invention, light emitting source 3-7 produces enough light through externally fed, and to whole light fixture, can set light emitting source 3-7 is spot light.Simultaneously because light emitting source 3-7 is arranged at the perifocus place of reflector 3-6 inner surface; And reflector 3-6 inner surface type of being paraboloid structure; Thereby make the reflection of most light process reflector 3-6 inner surfaces that light emitting source 3-7 is launched, carry out radiation along the focal axis line direction of reflector 3-6 inner surface.
Further; Comprise a thermal insulation board 3-5, be arranged at the front end of reflector 3-6, the shape semicircular in shape; Heat-barrier material by properties of transparency is good is formed; Thermal insulation board 3-5 keeps vertical with the inner surface axis of reflector 3-6, thereby guarantees that reverberation not because of light refraction produces the light beam that is not parallel to reflector 3-6 inner surface axis, guarantees to reach the illuminating effect of expection.
Particularly, in embodiments of the present invention, thermal insulation board 3-5 is arranged at the front end of reflector 3-6, and thermal insulation board 3-5 is processed by transparent material, in order to reach effect of heat insulation, is evacuated in the middle of the thermal insulation board, thereby blocks heat conducting approach.Parallel rays through reflector 3-6 reflection passes thermal insulation board 3-5, reaches the inner surface of liquid crystal device 3-3.
Particularly, in embodiments of the present invention, liquid crystal device 3-3 is arranged at thermal insulation board 3-5 front end; It is basic identical that the shape of liquid crystal device 3-3 and thermal insulation board 3-5 keep; Thereby can make light pass through thermal insulation board 3-5 effectively, shine on the liquid crystal device 3-3, through such structural design; When the light that can guarantee to shine liquid crystal device 3-3 reached Design Theory, the heat and the liquid crystal device 3-3 that can also effectively light emitting source (bulb) 3-7 be distributed kept apart.Because light is to see through thermal insulation board 3-5 uniformly basically after through reflection, and through the micro-scattering effect of thermal insulation board 3-5, reverberation can be with the inner surface that is distributed in liquid crystal device 3-3 of uniform properties more.
Further,, can the transmission region of liquid crystal device 3-3 be set as definite shape, include but not limited to geometry pattern, animal pattern etc. according to the control strategy of peripheral control unit.Because the characteristic of liquid crystal device 3-3 self; Under the enough little prerequisite of liquid crystal cells; The printing opacity shape of liquid crystal can be arranged to any pattern and random color; Thereby make the light fixture of the present invention that is used to throw light on to realize intelligent lighting with the response speed and the more intelligentized field of illumination of more accelerating, can realize the light transmission of different colours simultaneously through the control deflection angle.
Further; Liquid crystal device 3-3 is connected with reflector 3-6 through the liquid crystal support; And the liquid crystal support have a plurality of liquid crystal devices can be installed simultaneously structure (in embodiments of the present invention; At most three liquid crystal devices can be installed simultaneously), to guarantee to realize the specific (special) requirements of more light combinations and light control.
Further; Comprise a liquid-crystal controller 3-4, liquid-crystal controller 3-4 is arranged at the bottom of liquid crystal support 3-8, and links to each other with liquid crystal device 3-3 through soft base circuit board; Thereby guarantee that liquid-crystal controller 3-4 is in the relatively low zone of temperature, is beneficial to the operate as normal of liquid-crystal controller.Liquid-crystal controller can be a kind of controller of the liquid crystal device the controlled light transmittance of arbitrary form; Because liquid crystal has anisotropic characteristics; Add that at the liquid crystal two ends different voltages with different can make the light transmittance of liquid crystal change; And above-mentioned liquid crystal cells is microminiaturized, and the liquid crystal cells of thousands of microminiaturizations carried out arranged, so just can realize that high-resolution light controls.Liquid-crystal controller 3-4 realizes what liquid crystal was controlled through controlling these thousands of liquid crystal cells light transmittances.
Further; Comprise a lens 3-1 and lens carrier 3-2, lens 3-1 is processed by transparent material, and lens 3-1 is arranged at lens carrier 3-2 front end; Lens 3-1 and liquid crystal device 3-3 keeping parallelism, lens 3-1 mainly act as the light reasonable distribution field of illumination through liquid crystal device 3-3.
