Up to upper, the fluorescence color separation wheel module and diffusion colour wheel module work under the control of synchronization control circuit, the Synchronization Control
Circuit includes the power management chip being connected with external power supply, receives the system control of standby voltage caused by power management chip
MCU, reception system control the main control chip of MCU power-on commands, receive the iridescent wheel drive of main control chip output control signal
Chip and diffusion colour wheel driving chip, and detect fluorescent powder color wheel module respectively and spread the fluorescence of colour wheel module running status
Colour wheel detection sensor and diffusion colour wheel detection sensor.
The rotating speed of the motor is 18000 revs/min, drives diffusion colour wheel module to rotate, laser beam is carried out at speckle
Reason, because diffusion colour wheel module is not in itself absolute uniform, the light beam for causing to project is worked as and expanded there is also the low phenomenon of uniformity
After dissipating colour wheel module on a motor rotated at a high speed, then it can make in laser beam unit period by spreading colour wheel mould
The different zones of group, so as to lift beam uniformity to a certain extent.
The beneficial effects of the invention are as follows：The double-colored wheel system for laser projection of the present invention, fluorescent powder color wheel module
One-wavelength laser light beam can be carried out exciting and produce other colors, the color enriched for systematic contributions, the module installation of diffusion colour wheel
On motor, it can make by the different zones of diffusion colour wheel in laser beam unit period, so as to lift light to a certain extent
Beam uniformity, fluorescent powder color wheel module and diffusion colour wheel module work under the feedback of synchronization control circuit, effective improving laser
The uniformity of projector's picture, produce comparatively ideal visual effect.

Lens module 24, fluorescent powder color wheel module 26 and diffusion color are installed between LASER Light Source module 23 and fluorescent powder color wheel module 26
Lens module 24 is also installed, the diffusion colour wheel module 27 is arranged on motor, the fluorescence color separation wheel between wheel module 27
Module 26 and diffusion colour wheel module 27 work under the control of synchronization control circuit 22, the synchronization control circuit 22 include with it is outer
The power management chip 2 of power supply connection is connect, the system control MCU5 of standby voltage caused by power management chip 2 is received, receives
System controls the main control chip 1 of MCU5 power-on commands, receives the iridescent wheel drive chip 3 of the output control signal of main control chip 1
With diffusion colour wheel driving chip 4, and the glimmering of fluorescent powder color wheel module 26 and the running status of diffusion colour wheel module 27 is detected respectively
Photochromic wheel detection sensor 6 and diffusion colour wheel detection sensor 7.The rotating speed of motor is 18000 revs/min, drives diffusion colour wheel mould
Group 27 is rotated, and speckle processing is carried out to laser beam, because diffusion colour wheel module is not in itself absolute uniform, causes the light projected
Beam can then make to swash there is also the low phenomenon of uniformity, and after colour wheel module is spread on a motor rotated at a high speed
By the different zones of diffusion colour wheel module in light light beam unit period, so as to lift beam uniformity to a certain extent.
As shown in Figure 2, main control chip 1, power management chip 2, iridescent wheel drive chip 3, diffusion colour wheel driving core
Piece 4, system control MCU 5, fluorescence colour wheel detection sensor 6, diffusion colour wheel detection sensor 7 pass through pcb board wire laying mode knot
Schematic diagram network is closed to be connected up according to nearby principle, make pcb board, welding component and connector, hot- line test.Connect
After 220V AC powers, power management chip 2 produces standby voltage 5V, feed system control MCU 5, and operating personnel pass through remote control
Or button exports power-on command to main control chip 1 by system control MCU 5, while out-put supply wake command is to power management
Chip 2, now system electrification 12V, the output control signal of main control chip 1 to iridescent wheel drive chip 3 and expands after delay 10 seconds
Colour wheel driving chip 4 is dissipated, starts to produce synchronized signal, realizes driving fluorescent powder color wheel module 26 and diffusion colour wheel module 27
Effect, two colour wheel modules is operated in synchronous regime, from realize the present invention system steady operation.Fluorescent powder color wheel simultaneously
Fluorescence colour wheel detection sensor 6 on module 26 and diffusion colour wheel module 27 can be in office of the same colour with diffusion colour wheel detection sensor 7
Wheel module feeds back a high level signal when being stopped and controls MCU 5 to system, and now system control MCU 5 can export shutdown
Order to main control chip 1, whole system is stopped, so as to realize to fluorescent powder color wheel module 26 and diffusion colour wheel module 27
Protective effect, the especially protection to fluorescent material on fluorescence colour wheel.
As shown in figure 1, by control circuit 22, fluorescent powder color wheel module 26, spread colour wheel module 27, LASER Light Source module
23rd, lens subassembly 24 fits together, and detects feedback signal 30, diffusion according to LASER Light Source drive signal 33, fluorescence colour wheel
Colour wheel detects feedback signal 31, and the connection request of power supply signal 32 is attached wire harness, connects general supply, and run what is matched
Software, you can final to lift picture uniformity with normal work.
In figure 3, after system receives power-on command, system control MCU5 first wakes up power supply, power supply is exported 12V to master
Chip 1 is controlled, after postponing 10 seconds, system control MCU5 sends power-on command and sends control command to main control chip 1, main control chip 1
To fluorescent powder color wheel module driving chip 3 and diffusion colour wheel module driving chip 4, driving chip 3 and the module driving of diffusion colour wheel
Chip 4 sends drive signal to fluorescent powder color wheel module 26 and diffusion colour wheel module 27, and sends synchronization by system control MCU5
Signal is to fluorescent powder color wheel module 26 and diffusion colour wheel module 27, so that fluorescent powder color wheel and diffusion colour wheel start synchronous work
Make, while fluorescent powder color wheel module 26 passes with the fluorescence colour wheel detection sensor 6 on diffusion colour wheel module 27, diffusion colour wheel detection
Sensor 7 monitors fluorescent powder color wheel and diffusion colour wheel working condition in real time respectively, runs into because fail operation stops or job insecurity,
High level signal can then be fed back and control MCU5 to system, system control MCU5, which then can quickly send shutdown command, first makes main control chip
Shutdown, turns off power supply 12V, realizes whole system protective effect.
