Other considerations in lighting design standards 1 . Emergency Lighting China's "Residential Building Code" (GB 50368-2005) stipulates that emergency lighting shall be provided for stairwells, elevator rooms, and their front rooms in 10-story and 10-story residential buildings.

In the "Architectural Lighting Design Standards", corresponding provisions are made for setting the illumination intensity of emergency lighting:

(1) The illuminance of evacuation evacuation channels shall not be less than 0.51x;

(2) The illuminance of the safety lighting is not lower than 5% of the general lighting illuminance of the site;

(3) The illuminance value of the standby lighting, unless otherwise specified, shall not be less than 10% of the general illuminance of the site.

2. The selection of light sources and lamps (1) In the rooms with lower height, a straight tube fluorescent tube with a narrow diameter should be adopted;

(2) Store halls should adopt narrow-pipe straight fluorescent lamps, compact fluorescent lamps or low-power metal halide lamps;

(3) High-rise industrial plants can use metal halide lamps or high-pressure sodium lamps, or high-power thin-tube lamps;

(4) Fluorescent high-pressure mercury lamps should not be used in general lighting locations, and self-ballasted fluorescent high-pressure mercury lamps should not be used;

(5) Under normal circumstances, indoor and outdoor lighting should not use ordinary lighting incandescent lamps;

(6) Incandescent lamps can be used in the following places:

1) Where an instantaneous start and continuous dimming are required, when other light source technologies are economically unreasonable;

2) places with strict requirements for preventing electromagnetic radiation interference;

3) frequent switching lights;

4) places with low illuminance and short lighting time;

5) Places with special requirements for decoration.

3. Illumination notes for other special occasions (1) The lighting of the library's library, especially those where precious materials are stored, should use light sources with little or no ultraviolet radiation;

(2) The lighting of restaurants and bedrooms should use low color temperature light source;

(3) When designing classroom lighting, the long axis of fluorescent tubes should be arranged perpendicular to the blackboard to reduce the interference of direct glare.

Electric Blanket Switch With Three Settings 0-1-2-3-0, setting 1 is 15W which is suitable for all night use, setting 2 is 30w for people who requires more heat, setting 3 is 60W for preheating function.   

Two "0" means you can turn off the electric blanket by the two sides. Blind spot design make it possible to let the blind people use the electric blanket easily also let user know the setting he set in dark.

Invisible light make it more safe.

The heating wire matches to the three settings controller are with double helix heating elements, it means when the inner is heating, the outer will act as heating function, while the outer is heating, the inner will be protection function, in this way, it expands the life of the electric blanket.
