Technical field
Colour wheel technical field is the utility model is related to, more specifically to a kind of light supply apparatus and colour wheel.
Background technology
At present, laser fluorescence powder technology is quickly grown, and is widely used.Laser fluorescence powder technology, i.e., with sharp
Light beam excitation fluorescent material produces fluorescence, usually using blue laser as exciting light.In visible-range, the energy meeting of photon
With wavelength into Negative correlation, wavelength is shorter, and photon energy is bigger, therefore, when with the blue LASER Excited Fluorescence powder of short wavelength,
The higher blue laser photon of energy can be absorbed by phosphor material powder, and the long wavelength's fluorescent photon for giving off energy relatively low.
Due to the needs of radiating, fluorescent material and its carrier are generally made to the shape of colour wheel together with the motor of high speed rotation
Formula.During rotation, the difference of wheel surface height can reduce the launching efficiency to fluorescent material, and cause fluorescence optical axis
Skew, follow-up optical energy utilization efficiency and brightness uniformity can all be lost.Therefore, it is necessary to a kind of apparent height uniformity compared with
Good light supply apparatus.
Light supply apparatus of the prior art is as shown in figure 1, the transmitting repeated lens 212 of laser beam of laser 211 are imaged
In the surface of fluorescent material 201, excitated fluorescent powder is produced fluorescence and reflected in the form of Lang Baiguang.Fluorescent material 201 and its carrier 202 are logical
Cross glue 206 to be bonded in the locating slot 207 of colour wheel substrate 204, the locating slot of colour wheel substrate 204 is as shown in Figure 2.Drive motor
205 can drive colour wheel substrate to rotate at a high speed.
When being bonded fluorescence powder carrier 202 with colour wheel substrate 204 with glue 206, because glue is liquid, there is flowing
Property, the smearing of glue amount is uneven and pressure is uneven during clamping, easily causes fluorescence powder carrier 202 and tilts, glimmering
Light powder apparent height is inconsistent.
Can so make colour wheel when rotating indigo plant laser phosphor surface into picture when and it is clear when and obscure, cause laser
Efficiency it is inconsistent, and reflect fluorescence optical axis can be offset to different directions.Finally, color and the brightness of illumination light can be caused
It is uneven.
Therefore, how to solve in the prior art, the crank-sided problem of fluorescence powder carrier, to turn into those skilled in the art institute
The important technological problems to be solved.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of colour wheel, and it can avoid wavelength convert part easy
