Abstract
The invention discloses a projector. The projector comprises a shell, a main controller, a power supply and an optical system, wherein the optical system comprises a lens and an illumination device arranged on the rear part of the lens; and the illumination device is a polyhedral light-emitting diode (LED) lamp which is connected with the power supply. The polyhedral LED light source is used as the illumination device of the projector, and rays are emitted from both the side and the top, so that the illumination angle reaches 270 degrees, the angle illumination requirements of a projecting lamp can be greatly met, the polyhedral LED light source is low in heat productivity, and after the polyhedral LED light source is used for a long time, the redundant heat can be quickly emitted through a heat sink and the effect is good; therefore, the application prospect of the projector is wide.
Description
Technical field
The present invention relates to a kind of projector, especially a kind of projector that possesses the polyhedron lighting device.
Background technology
Projector is as a kind of imaging device, be widely used in education, commercial, places such as family, continuous development along with shadow casting technique, can export high resolving power and big figure picture digital projector application more and more widely, in order to make projector reach the requirement of high brightness and sharpness, usually use the light source of powerful bulb module as projector, but at present mainly have following shortcoming as the light fixture of light source of projector on the market: (1) adopts the planar package form, lighting angle is little, existing LED increases lighting angle as modes such as pointolite need scioptics, even if after the modes such as scioptics, effect is still undesirable, and lighting angle does not reach requirement; (2) the light fixture thermal value is too high, and existing LED when high-brightness light is provided, can produce very big heat, and the change conference of heat directly influences the optical quality of lens as pointolite, and the performance to whole projector exerts an influence then; (3) luminous flux relatively a little less than, the luminous flux of existing LED unit wattage is about 50 ~ 70 lumens; (4) lack serviceable life, generally be no more than 5000 hours, and shockproof effect is poor, damage easily; (5) need the preheating of a period of time, can not reach that promptly to open be bright effect etc.
In view of the weak point of above-mentioned existing projector, therefore be necessary existing projector is made improvements.
Summary of the invention
At above-mentioned pointed weak point, the object of the present invention is to provide a kind of projector that possesses polyhedron LED light fixture.
The technical scheme that the present invention is adopted for its technical matters of solution is:
A kind of projector, comprise shell, master controller, power supply and optical system, described optical system comprises lens and is located at the lighting device at lens rear portion, it is characterized in that: described lighting device is a polyhedron LED light fixture, described polyhedron LED light fixture links to each other with power supply, described polyhedron LED light fixture comprises pedestal and LED lamp pearl, and pedestal is provided with a polyhedron, and described polyhedral each side and top are provided with LED lamp pearl.
Further, described polyhedral side and top scribble fluorescent powder.
Further, described polyhedron is octahedra.
Further, be provided with radiator in the described shell, described LED light fixture is fixed on the radiator.
In addition, the bottom of described pedestal is provided with connecting screw, and described radiator is provided with the screw of fixedly connected screw.
The invention has the beneficial effects as follows: the present invention is as a kind of projection lamp that possesses polyhedron LED lighting source, on the one hand, the present invention uses the lighting device of polyhedron led light source as projector, light emission is all arranged at side and top, make its light angle reach 270 °, can greatly satisfy the demand of projection lamp angular illumination; On the other hand, polyhedron led light source thermal value used in the present invention is low, and after long-time the use, unnecessary heat can pass through the radiator quick heat radiating, and is effective; Secondly, the strong and long service life of luminous flux, owing to adopt the multi-angle emission, the luminous flux of the polyhedron LED that the present invention uses can reach 110 lumens, and anti-seismic performance is stronger; In addition, the present invention needs the warming up period of a period of time just can open unlike the conventional bulb module, but can plug and play.
