Electric lighting is the use of electrical energy shine a light source. According to the luminous principle can be divided into thermal radiation and gas lighting light source. According to the use of nature can be divided into work lighting, decorative lighting and emergency lighting. Fire hazard sex
1. Lighting or decoration at work, the glass bulb, tube surface temperature is very high. If there are obstacles of the improper selection of lamps and lanterns, electric spark, arc or local high temperature, are most likely to cause the fuel burning near lamps and lanterns, caused the fire.
2. Due to the lighting lamps and lanterns is generally installed in the production and living places, decorative lamps and lanterns is generally installed in crowded places, once there is a fire in addition to cause huge property losses, also will cause heavy casualties.
3. Incandescent lamp at work, its surface will be hot. And the greater the power, continuous use, the longer the higher the temperature, the surface or near contact with combustible, the heat dissipation, the accumulation of heat can roast burning fuel. In addition, the incandescent light bulb seismic resistance difference is easily broken and make the hot filament exposed, hot bulb fragments also easy to cause fire.
4. Fire hazard mainly on the ballast of fluorescent lamp. If the manufacturing quality is unqualified, cooling condition is bad or power rating and do not form a complete set of tube lights, the internal temperature will rise sharply, high temperature for a long time can damage the insulation of the coil turn-to-turn short circuit that produces instant huge quantity of heat, ignition fuel around. With the development of science and technology and the continuous improvement of people's living standard, all kinds of electric lighting and decorative devices widely used in the production and living. Because of its universality and diversity, and use for use in our daily life more incandescent lamp, fluorescent lamp, high pressure mercury lamp, halogen tungsten lamp lighting the fire risk of lamps and lanterns should have enough attention.
5. High pressure mercury lamp and sodium lamp power is larger, generally in more than a few hundred watts, lighting lamps and lanterns of the surface temperature is very high. High temperature is the main likehood of this two kinds of lamps and lanterns. Secondly, high pressure mercury lamp and high pressure sodium lamp electronic ballast trigger there is fire hidden trouble. Ballast fire hidden danger, such as the fluorescent lamp ballasts, while electronic trigger can be created due to internal capacitor leakage caused by heat burning.
6. The normal work of the halogen tungsten lamp, quartz glass tube wall temperature as high as 500 ~ 800 ℃, can not only roast burning of fuel in a short time, also could fuel roast burning within a certain distance, the fire risk than other more general lighting appliances.
7. Special effects ballroom lamp includes a beehive lights, scanning lights, sun lamp, lamp, skeet lamp and the universe itself not glowing snowball lights, etc. Its characteristic is the lamps and lanterns is adornment and apply colours to a drawing atmosphere often with motor drive mechanism to the lamps and lanterns. When the rotational resistance increases or actuator stuck, the motor will quickly fever heat, combined with the stage props of the place such as curtain scene more for fuel, in motor under the action of high temperature easy to fire.
8. The neon of trigger voltage above 10000 v, need special transformer booster to acquire. If the transformer high voltage output end insulation terminal there is dirt on product, light leakage may occur under the wet weather, fire. At the same time for a long time electricity will also because of high temperature melt filling and sealing on the transformer of asphalt and accidents.
9. Electric lighting and decoration process, besides all sorts of lamps and lanterns of lighting and decoration, still needs a lot of switches, protector, wires, ceiling rose, lamp holder and lamp box, stents, such as attachment, if these facilities due to improper selection capacity, long-term overload operation such as insulation damage causes. Short circuit failure also can cause fire accidents such as fire.
