The surface mounted luminaire refers to the light that its mounting surface is close to the ceiling of the building, and often is used in the lighting of the rooms. The inner light can use common incandescence bulb, fluorescent lamp, high-intensity gaseous discharge lamp, and tungsten halogen lamp, etc. the surface mounted luminaire of various light sources is suitable to different places. the surface mounted luminaire of incandescence light and fluorescent lamp mainly is used in the lighting of 3-meter places such as: room, classroom and office building, etc. The high-intensity gaseous discharge lamp with big power and light source is mainly used in the lighting of 4-9 meters places such as: gym, big marketplace and workshop, etc.
In order to save energy and obtain enough brightness, the surface mounted luminaire is the first choice for the lighting of room, school, shop and office, which should meet basic requirement in safety.
The requirements of the lights in safety and electromagnetic compatibility1, inside/ outside wiring section area of the lights should be more than 0.5mm2/0.75 mm2。2. the light should be lasting in use. The lights of fluorescent light should be chosen that it can not only work under the normal conditions, but offer extra protection ballast when the bulb is ageing or destroyed. The shell, light cover and insulating light base etc. of incandescence bulb in the endurance testing is not burnt and deformed. 3. enough creepage distance and electric clearance; 4. the insulating materials of main safe components should be thermal & fire proof;5. enough electrical shock protective device6. reasonable structure design and complete process technology; 7. the electromagnetic disturbance is within the limited value of standard regulation; 8. the harmonic wave current is within the limited value of standard regulation;
How to buy surface mounted luminaireThe surface mounted luminaire is often used in home, office and meeting room, etc. The safety of the light is the first consideration when you buy, and you also take the size, height and function of the room into account.
