Wiring method: Each emergency light fixture should be set up with a dedicated line, and no switch is set in the middle. Two-wire and three-wire emergency luminaires can be connected to a dedicated power supply. The setting of each dedicated power supply should be combined with the corresponding fire protection code. Where the emergency power supply is placed separately from the luminaire, the electrical connection shall be made of high temperature resistant wires to meet the fire protection requirements. Two-wire system The connection method is a common connection method for special emergency lamps. It is suitable for use in emergency lights without lighting. After the power is cut off, the emergency lights are automatically illuminated. It is also suitable for the micro-power emergency light to be on and off normally. After the power is cut off, it will turn into emergency and continuous lighting. Three-wire system The connection method is the connection method of the emergency light, which can control the normal opening and closing of the emergency light. When the external circuit is powered off, no matter what state the switch is in, the emergency light immediately lights up. K is a usual lighting switch.

Plane ruled gratings are characterized by a superior efficiency at their design wavelength compared with holographic gratings. Plane Ruled gratings comprise the majority of diffraction gratings used in spectroscopic instrumentation and are especially useful in systems requiring high resolution.
China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, reflective gratings,holographic gratings,concave gratings etc. to meet different needs. Maximum ruled area is up to 300 x 300 mm for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from 20 grooves per millimeter to 2400 grooves per millimeter, wavelength from 0.2 micron to 25 microns.
