Abstract
The utility model discloses an LED radiating structure of an LCOS projector. The LED radiating structure comprises a lens, a light machine, an LCOS liquid crystal board and a PCB, wherein the lens isconnected with the light machine which is connected with the PCB via the LCOS liquid crystal board, an LED light source disposed on the lower portion of the light machine is fixed on a radiating fin,and a fan is installed on the radiating fin. Compared with the prior art, the LED radiating structure conducts heat produced by an LED by installing the aluminum base board radiating fin on the LED light source of the LCOS light machine, and emits heat energy through the fan mounted on the radiating fin, thereby ensuring normal working of optical elements in an illuminating system inside the lightmachine, and avoiding the problem that the internal elements of the light machine are damaged caused by overhigh temperature.
Description
Technical field:
The utility model relates to LCOS (Liquid Crystal on Silicon, liquid crystal on silicon) projector, and particularly a kind of is the radiator structure of the LCOS projector of light source with LED.
Background technology:
At present, the LCOS light source of projector adopts the UHP light source mostly, has the weak point in serviceable life, and the long-time relatively important disadvantages of back brightness decay of using for this reason, mainly utilizes LED to replace original UHP light source for light source now.
It is big with LED to be that the LCOS projector of light source has a brightness of illumination, the characteristics that luminous energy density is high, but exist LED to produce heat in ray machine inside big, the problem of weak heat-dissipating, especially the resistance to elevated temperatures of the LCOS liquid crystal board self in the ray machine is poor, in case temperature surpasses its tolerance range, will cause the cause thermal damage of LCOS liquid crystal board.
Be beneficial to heat radiation though can fan be installed in the comparatively serious led section of ray machine heating, owing to stopping of optical element in the illuminator, it is not smooth to cause exhaust stream to flow, and radiating effect is bad.
Summary of the invention:
For addressing the above problem, the purpose of this utility model is to provide a kind of LCOS LED of projector radiator structure, led light source is fixedly mounted on the heat radiator by coupling agent, its heat can in time be distributed, to reduce the influence of heat that LED produces the ray machine inner member.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of LCOS LED of projector radiator structure, comprise camera lens, ray machine, LCOS liquid crystal board and pcb board, above-mentioned camera lens is connected with ray machine, ray machine is connected with pcb board by the LCOS liquid crystal board, described ray machine bottom is provided with led light source, this led light source is fixed on the heat radiator, on the described heat radiator fan is installed.
Connect by coupling agent between described led light source and the heat radiator.
Described LCOS liquid crystal board is provided with heat radiator.
Described heat radiator is an aluminium base.
The utility model is by fixing an aluminium base heat radiator on the led light source of LCOS ray machine, the thermal conductance that LED is produced goes out, and then heat is exhaled by the fan that is installed on the heat radiator, thereby guaranteed the operate as normal of optical element in the ray machine interior lighting system, avoided the too high and problem that causes the ray machine inner member to damage of Yin Wendu.
Description of drawings:
Fig. 1 is the utility model perspective view.
Fig. 2 is Fig. 1 lateral plan.
Identifier declaration among the figure: camera lens 1, ray machine 2, LCOS liquid crystal board 3, pcb board 4, loudspeaker 5, heat radiator 6, fan 7, led light source 8.
Embodiment:
For setting forth thought of the present utility model and purpose, the present invention is described further below in conjunction with the drawings and specific embodiments.
See also Fig. 1～shown in Figure 2, the utility model relates to the radiator structure of led light source in the LCOS projector.Wherein LCOS projector mainly includes electric control system part and light engine part, and the electric control system part mainly is integrated on the pcb board 4 here, and the light engine part then comprises parts such as ray machine 2, LCOS liquid crystal board 3.Wherein ray machine 2 front ends are connected with camera lens 1, and the rear end then is connected with LCOS liquid crystal board 3, and described camera lens 1 lower end is provided with camera lens 5, and ray machine 2 inside mainly include light-collecting lens, deflection Amici prism etc., and the lower end then is led light source 8 (see figure 2)s.
Described led light source 8 is installed in the reflector of ray machine bottom, to realize that the light that LED sends is all reflexed to light-collecting lens in the ray machine 2, and light is converged by this light-collecting lens, the deflection Amici prism PBS that is transmitted into then in the ray machine 2 carries out beam split, produce the light beam of P direction and S direction, wherein the light beam of P direction then reflexes on the LCOS liquid crystal board 3 by the spectro-film of deflection Amici prism PBS.Because LCOS liquid crystal board 3 is connected with pcb board 4, converting picture signal to photosignal by pcb board 4 sends on the LCOS liquid crystal board 3, and the generation image file, behind the light beam that these image file cooperated with LED light sources 8 produce, then directly from camera lens 1, project on the projection screen.
Here led light source 8 is connected with pcb board 4 by led drive circuit, and led light source can produce heat at work, so the utility model installed heat radiator 6 and fan 7 on led light source 8, so that the thermal transpiration that led light source 8 is produced is gone out.
More than the LCOS LED of projector radiator structure provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
