What are the specific functions of various common lighting fixtures, such as chandeliers, ceiling lamps, downlights, wall lamps, activity lamps, and architectural lighting?
(1) Chandeliers:
Generally, the luminaires suspended from the ceiling are the most commonly used general illuminations, including direct, indirect, downward illumination and astigmatism. The size of the chandelier and the number of lamps are related to the size of the room. The chandelier is generally 500~1000 mm from the ceiling, and the center of the light source is 750 mm from the flowering board. It can also be high or low depending on the specific needs.
(2) Ceiling light:
Light type mounted directly on the ceiling. Including the downward projection lamp, astigmatism and comprehensive lighting, the light source has incandescent ceiling and fluorescent ceiling lamp, which is characterized by brighter ceiling and full brightness of the room. The disadvantage is that it is prone to glare. Because it is relatively low in general residential floors, it is widely used. However, the shape, layout, structure and materials used of the ceiling lamp should be considered according to the requirements of use, the structure of the ceiling and the aesthetic requirements. The scale of the luminaire should be compatible with the indoor space, and the structure must be safe and reliable.
(3) Undercarriage lights:
Refers to the hidden luminaire embedded in the ceiling, the ceiling is connected to the ceiling, usually a direct light type with a downward volley. This type of lamp is not used in general residential buildings. More in air-conditioned and suspended rooms. However, due to the darkness of the downlight, it is often used in conjunction with other lamps.
(4) Wall lamp:
Wall lights are fixtures that are mounted on a wall. It is a light fixture for people who have light interior decoration and supplementary lighting. Because it is not high from the ground, low wattage bulbs are generally used. The height of the lamp itself is 450~800 mm for large and 275~450 mm for small. The diameter of the lampshade is Ф150~250 mm, and the small Ф110~130 mm. The distance between the lamps and the wall surface is roughly 95~400 mm. Commonly used light source power for wall lamps, large-scale use of 100-watt, 150-watt incandescent bulbs, small use of 40-watt, 60-watt incandescent bulbs. It is also possible to replace incandescent bulbs directly with compact fluorescent lamps.
(5) Activity lamps:
It is a luminaire that can be placed freely as needed. Table lamps on the desktop and floor lamps on the floor belong to this type of fixture. It is the most flexible type of lamp. The height of the large falling knife is 1520~1850 mm, the diameter of the lampshade is 400~500 mm, and the 100 watt incandescent bulb is used. The total height of the small falling lamp is 1080~1400 mm or 1380~1520 mm, and the diameter of the lampshade is 250~450. In millimeters, use 60-watt or 75-watt, 100-watt incandescent bulbs; medium-sized floor lamps are 1400 to 1700 mm high. The total height of large lamps is 500~700 mm, the diameter of lampshades is 350~450 mm, and the bulbs of 60 watts or 75 watts and 100 watts are generally used when using incandescent lamps; the total height of small lamps is 250~400 mm, and the diameter of lampshades is 200. ~350mm, 25-watt or 40-watt bulbs are generally used when incandescent lamps are used; medium-sized lamps have a total height of 400-550 mm.
(6) Architectural lighting:
Also known as structural lighting, it refers to line or face lighting that is fixed to the ceiling or wall. There are usually a variety of ceilings, seesaws, curtains and light walls. Structured lighting generally uses fluorescent tubes as the light source. The ceiling type is indirect illumination, the seesaw type is direct illumination, and the others are mostly semi-indirect astigmatism. This type of lighting is usually used for background lighting or decorative lighting and must be considered as a whole for the structural elements of the building. There are many types of lamps and openings, and they can be selected according to the style, function and personal preference of each room.

An electrical appliance used to protect electrical equipment from high transient overvoltage hazards and to limit the duration of continuous flow.This term includes any external clearance necessary for the normal functioning of the appliance during operation and installation, whether or not it is a unit as a whole.
Surge protector, also known as lightning arrester, is an electronic device that provides safety protection for all kinds of electronic equipment, instruments and communication lines.When the electric circuit or communication lines or for outside disturbance suddenly produce peak current in voltage, surge protector in a very short time conduction tap, to avoid surge damage to other devices in the circuits.[1]
Surge protector, suitable for ac 50/60 hz, rated voltage 220 v to 380 v power supply system, the indirect lightning and thunder and lightning directly affect transient over voltage surge protection, or other applicable to the family home, the third industry and the surge protection industry requirements.
