Specification for design and installation of lamps and lanterns: process standards must be strictly followed
A hook for fixing a lantern.The diameter of the round steel should not be less than that of the lamp hanger pin hookAnd not less than 6 mm. For large lanternsThe fixing and hanging device of the hoisting lantern should be tested according to 25 times the weight of the lamp.
Before the installation of the lamp, the lamp and its accessories should be complete, and there should be no mechanical damage, no deformation, paint peeling and lampshade rupture and other defects.
Specification for installation of indoor lighting lamps and lanterns (1) when steel pipe is used as the suspender of lamps and lanterns, the inner meridian of steel pipe is generally more than 10 mm, and the thickness of steel pipe wall is more than 5 mm. (2) the lamp line of the hanging chain lamp should not be pulled. The lamp line and the hanging chain are connected together, so it is easy to use.
Scope of application: this internal construction technology and testing standards are applicable to all indoor ordinary lighting installation projects under construction by Hengxin Digital Creative School Guizhen Design Company. Construction preparation 1 material 1 pay attention to check whether the nominal type of lamps and lanterns meet the requirements, and there should be product qualification certificate, and ordinary lights have safety certification marks.
A complete set of specifications for the installation of lighting lamps and lanterns
Emergency lighting installation specification the average installation height of emergency lighting is about 2 meters, but this height is not mandatory, but should be flexibly adjusted according to the actual use.
The fixture should be firm and reliable. There should be no less than two wooden screws or bolts for each luminaire. The 21-day lamp and its accessories should be used together, and the installation position should be convenient for inspection and maintenance, and there are measures to prevent the lamp tube from falling due to the loosening of the lamp corner. 22 equipotential connection end box equipment shall not be destroyed or shifted privately.
The number of bolts (or screws) for fixing the lamp should not be less than 2. Lamps and lanterns shall not be installed on combustible components. The switch of the lamp and electrical equipment must be installed on the “phase line” (that is, the control phase line), otherwise, after the switch is off, the lamp and electrical equipment will still be charged, which is easy to cause electric shock.
The installation regulations of lamps and lanterns are as follows: 1 each individual branch circuit is not allowed to have more than 25 lamp holders, except lanterns and colorful lanterns, which are not allowed to exceed 10A in general. 2 the screw lamp must be connected to the phase line at the central point, and the zero line must be connected to the threaded terminal. 3 when the weight of the lamp is greater than 2kg, it should be fixed with expansion screw.
Requirements for warehouse lighting fixtures
Mobile lighting fixtures are not allowed in the warehouse. Items are not allowed to be stacked under the lighting fixtures, and the distance between the vertical lower part and the horizontal level of the stored items shall not be less than 0.5 meters. The distribution lines laid in the warehouse should be protected by metal pipes or non-flammable hard plastic pipes.
According to the fire requirements for the warehouse: the incandescent lamp should not exceed 60W and the LED energy-saving lamp should not exceed 300W, and the floor illumination of the warehouse should at least reach 50lux.
Packaging, metering, surface treatment, warehouse lighting brightness standard 750-300. The brightness standard of dyeing, casting and electric room lighting is 300-150. Entrance and exit, corridor, passageway, staircase, toilet lighting brightness standard 150-75. The lighting brightness standard of fire escape and outdoor power equipment is 75-30.
The finished product warehouse used to store cartons does not require explosion-proof lamps, but high-temperature lighting lamps such as iodine tungsten lamps and incandescent lamps with more than 60 watts are not allowed. When using low-temperature lighting lamps such as fluorescent lamps and other fire-proof lighting lamps, fire protection measures such as heat insulation and heat dissipation shall be taken for the ballast.
A 100W light. Every 50 square meters need at least one lamp, and 50 square meters need about 100W power, and 500 square meters need at least 10 100W lights. If the wattage is high, it can also be reduced by an appropriate amount.
Explosive warehouse is a dangerous environment, the corresponding lighting needs to meet the requirements of explosion protection and corrosion protection, as well as high temperature resistance and waterproof characteristics.
Is there any requirement for the installation height of the lamp?
In the substation, lamps and lanterns should not be installed directly above the high-voltage and low-voltage distribution equipment and bus. The height of the lamps and lanterns installed outdoors should not be less than 3 meters from the ground; when installed on the wall, the height from the ground should not be less than 5 meters.
The installation height of indoor fixed lamps and lanterns is not lower than? Can not be less than 2.5 meters, unlike people as tall as Yao Ming, ordinary people can not touch it.
Generally, when installing a chandelier, you need to calculate it according to the clearance of the living room. Before buying it, you must look at the specific height. Ordinary commercial housing is about the same. If it is a villa, it will be different. When you choose, the merchant will recommend it to you as appropriate.
