Description
Technical field
The present invention relates to a kind of colour wheel, particularly a kind of colour wheel that is applied to optical projection system.
Background technology
Because under the multiple demand of big display area, miniaturization and lightweight system, image projecting system becomes one of subitem the most popular in the present opto-electronics.
Popular now optical projection system is divided into and is the three major types type, be respectively liquid crystal projection display (Liquid Crystal Display Projector, LCD), monocrystalline silicon LCD (LiquidCrystal on Silicon, LCoS) and the digital light processor (Digital LightProcessing, DLP).Wherein, LCoS and DLP have the advantage that system oversimplifies, and will be the example explanation with DLP below.
DLP projector adopts digital control, utilizes the reflected light principle to carry out start simultaneously.At first, light source is via light harvesting post (Light Integration Rod) light harvesting, pass the colored filter beam split in the colour wheel again after, be projected to the digital micro-mirror wafer (Digital Micro-mirror Device, DMD) on.In this technology, replace in traditional liquid crystal projector by the digital micro-mirror wafer, be responsible for presenting the liquid crystal face version of image.Owing to have many small movable lens on the digital micro-mirror wafer, control movable lens angle of inclination and deflection period with drive electrode, the reflection direction by switches light throws imaging by camera lens again.
Wherein, colour wheel is bonding on the motor and is formed to stick together glue by colored filter, again the drive by motor so that colored filter rotate along the center.Yet,, and then cause the operating temperature of whole optical projection system also high owing to 950 ℃ to 1000 ℃ of intrasystem light-source temperature Chang Gaoda.Owing to stick together glue easy embrittlement under high temperature, so the high temperature that light source produced not only reduces the serviceable life of colour wheel, simultaneously, the fiduciary level of other element is also influenced.
For solving this problem, existing way is arranged at fan near light source, look source and the digital micro-mirror wafer, and the wind-force that utilizes fan to produce reduces environment temperature and self temperature of these elements.But at present the deisgn approach of electronic installation is light, thin, short, little, as if will fan being set in addition in original system again, be bound to the volume and the weight of increase total system.
Summary of the invention
Because above-mentioned problem the objective of the invention is to overcome the deficiencies in the prior art and defective, provide a kind of colour wheel that solves high temperature problem in the optical projection system.
For reaching above-mentioned purpose, the invention provides a kind of colour wheel, comprise a motor, a colored filter and a sets of fan blades, wherein, motor is made up of with a motor body axle center lid, and the axle center lid is arranged at a side of motor body, and the axle center lid rotates along a central shaft with motor body; Colored filter is arranged at the axle center lid; Sets of fan blades has several blades, and sets of fan blades is arranged at colored filter.
For reaching above-mentioned purpose, the present invention also provides a kind of colour wheel, comprises a motor, a colored filter and a sets of fan blades, wherein, motor is made up of with a motor body axle center lid, and the axle center lid is arranged at a side of motor body, and the axle center lid rotates along a central shaft with motor body; Colored filter is arranged at the axle center lid; Sets of fan blades has several blades, sets of fan blades be arranged at motor around.
For reaching above-mentioned purpose, also provide a kind of colour wheel in addition according to the present invention, comprise a motor, a sets of fan blades and a colored filter, wherein, motor is made up of with a motor body axle center lid, the axle center lid is arranged at a side of motor body, and the axle center lid rotates along a central shaft with motor body; Sets of fan blades has several blades, and sets of fan blades and motor are connected; Colored filter and sets of fan blades are connected.
From the above, colour wheel of the present invention has a sets of fan blades, by the rotation of sets of fan blades, and then the thermal source of optical projection system inside is disperseed, even leads the system outside.Compared with prior art, the present invention only adds sets of fan blades on original colour wheel, utilizes motor to drive the rotation start of colored filter, drives the rotation of sets of fan blades simultaneously.Owing to need not to add independently fan, the not only constancy of volume of total system, weight also increases seldom, spend also little, very suitable industry member use.In addition, the convection current that sets of fan blades produced also can reduce the temperature of motor, so that increase the serviceable life of colour wheel.Moreover, owing to reduced the temperature of total system, also promoted the fiduciary level of all the other elements.
