Product description
Parameters
An overview,
 
1. Product features
 
● obvious energy-saving effect: in the same brightness, than ordinary incandescent lamp energy-saving 90%, than energy-saving lamp energy-saving 65%.
 
● long service life: the average service life of LED light source can reach 50000 hours, avoiding frequent replacement of bulb or tube, realizing maintenance-free.
 
● environmental protection: no pollution, no ultraviolet radiation, is a new generation of green environmental protection lighting.
 
● wide working voltage range: the voltage changes within the range of 65 ~ 264V, the lamp works normally, and the brightness does not change at all.
 
The problem of high voltage fluctuation and easy burning lamps is solved effectively.
 
● products take the lead in the research of a new generation of thermal conductivity structure, lamps and lanterns to achieve a good thermal conductivity effect.
 
2. Main application and scope of application
 
Main application: used for safety lighting in inflammable and explosive environment such as gas and coal dust in underground coal mine, also used for lighting in places such as chemical industry, cement factory and flour mill.
 
Scope of application: it is applicable to the lighting of all the main roadway, chamber and underground mine.
 
3. Environmental conditions
 
1) ambient temperature: -20℃ ~ +60℃;
 
2) air relative humidity ≤95 ℃ (+25℃);
 
3) suitable for underground coal mine where gas and coal dust explosion hazard.
 
4. Model composition and its representative significance
 
The type of roadway lamp is compiled according to mt211-2005:
 
5 safety requirements
 
Riot type 1) product: the product adopts flameproof, flame-proof marked as: Exd Ⅰ
 
2) the product is equipped with safety warning board, and it is strictly prohibited to operate with electricity.
 
3) it is strictly forbidden to disassemble or replace parts and components underground. The maintenance and repair work of mining lamps must be carried out on the ground;
 
4) non-professionals are strictly prohibited from maintaining and repairing mine lamps;
 
Structure characteristics and working principle
 
1. Structural features: the roadway lamp is composed of power supply chamber, transparent tube cover, light source body, back cover and other components. The structure of roadway lamp is shown in the figure.
 
A clamping nut B power chamber C transparent tube cover D light source body E rear cover
 
2. How it works
 
The tunnel lamp adopts LED light source, ac 127V input voltage and flameproof lamp structure. After the lamp is assembled and installed, turn on the power, the LED light source will be lit, and the lamp will work.
