Rear-projection reflection system technology highlights
SR rear projection reflex system
Projection reflection system is large-screen projection display system is very important part. In rear-projection engineering installation, the regularly encounter projection space limited space. To resolve this problem, use a rear-projection screen dedicated reflector system, which uses mirrors to show beam reentry once or twice, in the show insufficient space for the projection distance to reach the show distance to ensure screen size. To use the reflectivity is greater than 90%, mirror flatness ± 0.02mm within the mirror, can guarantee the projection lamp luminance loss, reduction in minimum image distortion. Projection reflex system can effectively reduce the projection distance, avoid Sun effects (brightness not are relatively bright Center surrounded by dark) and other undesirable phenomena.
System reflection system consists of a positive vacuum coating reflector with a reflector bracket, a projector bracket.
Rear-projection mirror presentations and technical parameters using ordinary mirror coating on the back, then the projection of irradiating to the mirror, the coating to reflection, but also reflecting glass surface (Figure 1a) to form a double shadow. Of high quality face Coated reflector. It is different from normal mirror: with no ghosting and interface optical loss is small, resistance to oxidation, corrosion resistance, a dielectric film protection (see Figure 1b) and in the visible spectral region (380 ~ 700nm) with high reflectivity (see Figure 1b). Positive coated mirror reflectivity to 90-95% or even higher, making full use of solar energy, Visual effects better. Mainly used in projection TV, file projector, laser printers, fax machines, home theater, cameras, analytical instruments and other equipment.
Reflector bracket projector bracket
Projection reflection bracket imported high-quality steel, welding, surface adopts electrostatic spraying process: with corrosive, rust, fashionable, bracket with precise adjustment mechanism (universal regulators), installation and debugging a simple, easy to use, stylish in appearance, and other characteristics.
Rear-projection darkroom space calculation
The formula is as follows:
1: straight vote projection distance = length x off the bottom of the screen for projector lens of multiples
120 inch screen bottom-2489 (mm) x now ordinary projector lens multiples 2.0 = direct projection distance 4972 (mm)
2: a reflection of rear-projection distance = length x bottom edge of the screen to the projector lens multiples x0.6
120 inch screen bottom-2489 (mm) x now ordinary projector lens multiples 2.0x0.6 = rear projection distance 2983.2 (mm)
The above formula is only for reference, the actual distance depending on the environment and equipment, and other factors.

Rear-projection mirror introduction and technical data
General use coating on the back of the reflector, then the projection of irradiating to the mirror, reflection, glass coating to the surface to form a double shadow, reflection.
Of high quality face Coated reflector. It is different from normal mirror: with no ghosting and interface optical loss is small, resistance to oxidation, corrosion resistance, dielectric film protection and in the visible spectral region (380 ~ 700nm) has the advantage of high reflectivity. Positive coated mirror reflectance of 95% or even higher, making full use of solar energy, Visual effects better. Mainly used in projection TV, file projector, laser printers, fax machines, home theater, cameras, analytical instruments and other equipment.

Rear-projection reflex system installation and maintenance considerations:
1. the construction process
(1) keep the mirror using clean, dust-proof.
(2) the prohibition on hand to touch the surface, the operation is to wear a mask and gloves for spinning soft.
2. maintenance (quchen processing)
(1) soft duster can be dusted
(2) is not available water and other liquid solvent wipe the mirror
