Description
Technical field
The present invention relates to a kind of colour wheel group and colour wheel thereof, particularly about a kind of colour wheel group and colour wheel thereof that is used for optical projection system.
Background technology
Optical projection system can be divided into liquid crystal (Liquid Crystal Display according to its principle, LCD) optical projection system, monocrystalline silicon liquid crystal (Liquid Crystal on Silicon, LCOS) optical projection system and numerical digit light source treatment technology (Digital Light Processing, DLP) optical projection system or the like, and DLP has become one of shadow casting technique of present a new generation hot topic owing to have high brightness, correct color reproducibility, reaction time, no noise and advantage such as compact fast.
In DLP formula optical projection system, be to adopt numerical digit control, and utilize the reflected light principle, with after the light-source collecting via lens focus, after passing colour wheel group (Color WheelAssembly) again with filter element, be projected to numerical digit micro mirror wafer (Digital Micro-mirror Device, DMD) on.Owing to have many small movable lens on the micro mirror wafer, via driving circuit control movable lens angle of inclination and deflection period, again by the reflection direction of switches light by lens group with ray cast to the screen imaging.
Please refer to shown in Figure 1ly, it shows the side view of known colour wheel group.Colour wheel group 1 mainly is to comprise a filter element 11 and a motor 12.Wherein, motor 12 is to have axle center lid 121 and one motor body 122, and axle center lid 121 is sides that are arranged at an axis direction of motor body 122.In addition, colour wheel group 1 more can comprise positioning piece 13, and a winding displacement (figure does not show).This keeper 13 is that colour wheel group 1 is fixed in the optical projection system, and winding displacement is to be connected with a driver, and this driver is in order to CD-ROM drive motor body 122, and a bit (rotating shaft core) of establishing with keeper 13 and 122 of motor bodies is that rotate at the center.Wherein, motor body 122 mainly is made up of a magnet circle, a siliconized plate and a coil.When coil electricity, siliconized plate is to produce magnetic force and magnetic field, and allows magnetic field that orderly variation takes place by positive and negative and the intensity of electrical current, also is a rotating magnetic field, makes magnet circle and rotating magnetic field effect and then formation rotation.It is to utilize one to stick together on the axle center lid 121 that glue is fixed on motor 12 for a filter element 12, by the drive of motor 12 in order to do making filter element 11 rotations, in order to carry out beam split.At present the employed filter element 11 of industrial community is that glass plate by several pieces different colours combines, and filter element 11 for annular so that be arranged on the axle center lid 121 of motor 12.In addition, because filter element 11 is to utilize to stick together on the axle center lid 121 that glue is fixed on motor 12, therefore must heat to make and stick together adhesive curing, but the heat resisting temperature of motor 12 is about 80 ℃, therefore in heating process, cause motor 12 to damage easily, and because filter element 11 is by sticking together on the axle center lid 121 that glue is fixed on motor 12, therefore when motor or one of them damage of filter element, must put in order group scraps, can't reclaim another good element and reuse, thereby improve production cost.
Because the problems referred to above, the inventor urgently thinks a kind of colour wheel group and colour wheel thereof, with stick together glue heating process causes shortcomings such as motor 12 damages with motor 12 with the fixing shortcoming of adhesive means to solve filter element 11.
This shows that above-mentioned existing colour wheel group and colour wheel thereof obviously still have inconvenience and defective, and demand urgently further being improved in structure and use.In order to solve the problem that colour wheel group and colour wheel thereof exist, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.
