Description

a lighting device

technical field

The utility model belongs to the technical field of lighting equipment, in particular to a lighting device for a power system.

Background technique

Lighting lamps are devices that convert electric energy into light energy. The incandescent lamp is the most common one, with very low luminous efficiency, poor light color, and a rated life of 1,000 hours. However, it is still widely used because of its small size, convenient use, low price, and both AC and DC circuits. . Fluorescent lamps are often called fluorescent lamps because their light is close to natural light. Halogen tungsten lamp is a thermoluminescent light source using the principle of halogen cycle, and there are two types: iodine tungsten lamp and bromine tungsten lamp. Its luminous efficiency and light color are better than incandescent lamps, small in size and easy to use. In power plants, it is used as workshop area lighting, and it is also very common for on-site lighting in construction, and sometimes it is also used for drying and heating

The lighting device is composed of a bulb (tube), a lamp holder, a lampshade and a lamp holder. In order to make various light bulbs (tubes) suitable for different needs in different places, so people design various lamps. At present, the models of lamps and lanterns in our country are not uniform, and Shanghai, Beijing, Shenyang and other places each have their own models. According to the nature of use (taking Shanghai products as an example), it is divided into: factory lights; safety lights, explosion-proof lights; fluorescent lights; architectural lights.

Lamp holders are commonly known as lamp holders, and are divided into two types: bayonet (socket) and screw. The bayonet head is made of bakelite, which is suitable for low-power lighting; the screw lamp holder has two types of bakelite and porcelain, and the porcelain lamp holder is used for larger power bulbs. When wiring the screw lamp holder, be sure to connect the phase wire (live wire) to the center tongue, which is safer. The function of the lampshade is to scatter the light from the light bulb (tube) to the surroundings and change it to irradiate in the desired direction. It can be divided into direct light, semi-direct light, reflected light and diffuse light. The enamel metal lampshade used in the factory is the direct light type. It has high mechanical strength, good dust resistance, and all the light is emitted downwards, with high brightness. On architectural lamps and lanterns, lampshades of various styles made of opalescent glass are commonly used, such as glass ball lamps, which are diffuse light type, with beautiful shape and soft light, but the brightness is reduced due to more light loss.

The lamp holder is the fixed and supported part of the lamp, which is basically divided into two types: plumber and hanging chain. The tube light stand is composed of a flange and a hanging tube. The flange is generally cast into a disc shape with iron or aluminum. The bottom of the flange can be fixed on the roof or wall with screws, and the center of the top is threaded to the pipe end. The pipe is a steel pipe, the diameter is determined according to the needs, the wire passes through the pipe, and the pipe bends according to the light irradiation angle and the supporting square, and the bend is made into other forms.

However, these lighting devices are deficient in waterproof design to a certain extent, and when the existing lighting devices are used in the power system, there are often problems of one kind or another, such as complex structure of the lamps, poor durability, and short service life , and poor waterproof performance.
