Description
Technical field:
The utility model relates to a kind of projector, relates in particular to a kind of setting angle and adjusts self-adaptation heat dissipation type projector.
Background technology:
Projector generally is made up of projection imaging system and optical amplification system; Projection signal generally passes through the special processing of the imaging technique of projector; Become picture signal; Amplification through the optical amplification system in the projector again, projection signal could high-quality, be projected on the projective large-screen to high-resolution.When the imaging technique of projector is handled the projection input signal; Projector needs the very high brightness of intensity, guarantee high-intensity like this brightness output, and projector just must adopt powerful light source; And powerful light source is working long hours, and will certainly gather very big heat.Present projector on the market; Can only be just to put projection or hanging upside down projection, projecting direction and ground be level (the permitted maximum range is ± 10 degree), if projection bulb and ground angle are bigger; Untimelyly from projector, arrange these heats rapidly; These heats can deposit inner to bulb, thereby brightness is decayed rapidly, and cause the bulb blast probably; Under the situation of high temperature, the work efficiency of projector will reduce, and works down often, and also can shorten greatly the serviceable life of projector.
Summary of the invention:
The utility model provides a kind of radiating efficiency high setting angle adjustment self-adaptation heat dissipation type projector to the deficiency of above prior art.
For realizing the above object, the technical scheme that the utility model adopts is:
Setting angle adjustment self-adaptation heat dissipation type projector is made up of casing, optical system, Circuits System, camera lens, gravity sensing chip, CPU central controller, fan control chip, fan; It is characterized in that: have additional gravity sensing chip, CPU central controller and fan control chip in the optical system; The gravity sensing chip links to each other with the CPU central controller; Be provided with the fan control chip in the CPU central controller and link to each other, control the rotating speed of fan through the fan control chip with fan.
The soluble technical matters of the utility model is: after projector accomplishes and installs, adopt the gravity sensing chip to measure the setting angle of projector, the gravity sensing chip links to each other with the CPU central controller; The setting angle signal is transferred to the CPU central controller; The CPU central controller calculates the heat dissipation capacity that needs after projector installs, and controls the rotating speed of fan then through the fan control chip, thereby accomplishes the radiating treatment of different setting angles; Heat in the projector is discharged; And then the adjustment bulb heat radiation reach suitable temperature, prevent that bulb temperature is too high, prolong the serviceable life of projector simultaneously.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Embodiment:
As shown in Figure 1, setting angle adjustment self-adaptation heat dissipation type projector is made up of casing 1, optical system 2, Circuits System 3, camera lens 4, gravity sensing chip 5, CPU central controller 6, fan control chip 7, fan 8; It is characterized in that: have additional gravity sensing chip 5, CPU central controller 6 and fan control chip 7 in the optical system; Gravity sensing chip 5 links to each other with CPU central controller 6; Be provided with fan control chip 7 in the CPU central controller 6 and link to each other, control the rotating speed of fan 8 through fan control chip 7 with fan 8.
During enforcement, in projector's menu, can select to open the heat radiation of setting angle adjustment self-adaptation or close, after projector accomplishes and installs; Adopt gravity sensing chip 5 to measure the setting angle of projector, gravity sensing chip 5 links to each other with CPU central controller 6, and the setting angle signal is transferred to CPU central controller 6; CPU central controller 6 calculates the heat dissipation capacity that needs after projector installs; Control the rotating speed of fan 8 then through fan control chip 7, thereby accomplish the radiating treatment of different setting angles, the heat in the projector is discharged; And then the adjustment bulb heat radiation reach suitable temperature, prevent that bulb temperature is too high.
The utlity model has advantages such as simple in structure, easy to operate, good heat dissipation effect, have great promotional value.
