Electromagnetic induction lamp features

1. Electromagnetic induction lamp without electrodes and filaments, has a long life, long-term use of maintenance free, life is 100 times that of incandescent lamp, metal halide lamp 6-10 times.

2. High efficiency and energy saving, effective luminous efficiency of about 110Plm/w, power factor up to 0.99, 80% more than incandescent lamp power.

3. Good stability, voltage fluctuations in the range of 160-265v can start work.

4. Green environmental protection, through the national EMC test, no electromagnetic pollution, no stroboscopic, eye fatigue is not easy.

5. Instant start, start and restarty without delay, can instantly lit.

6. The light source color is good, color rendering index>=80.



1. Explosion-proof type compound or dust explosion proof type, suitable for gas or dust explosion hazardous area lighting.

2. Lamp comprises a light source chamber, electrical wiring cavity and cavity, closed type design.

3. The lamp shell is made of aluminum alloy die-casting molding. The electrical apparatus cavity containing the ballast, terminals and other electrical appliances, wiring cavity containing a user terminal. The light source is arranged inside the cavity mirror reflector lamps, the outer surface of polyester powder coating.

4. Polycarbonate pervious to light, high transmittance, good shock resistance. The electrical apparatus cavity cover opening structure for side.

5. The lamp has good corrosion resistance, high luminous efficiency, wide radiation rage, soft light, durable advantages.

6. The lamp is provided with a rubber fasket, reliable sealing, good protective performance.

7. Lamp modelling novel, beautiful appearance, convenient installation and maintenance. Suitable for low studio lighting.

8. Lamp shape A type and D type. Type A is suitable for pipe crane mounted, ceiling ceiling type installation and mounting. The type of D is applicable to fence pole mounted, vertical rod mounting flange.(see installation diagram). In addition to the pole mounted, A lamps factory installation port usually has a conductor, in oder to facilitate the user installation, but also can avoid the user installation is improper and the effect of explosion protection performance of lamps and lanterns.

9. Lamp can be arranged on the emergency power supply device, when the power supply network fault normal lighting lamps can be stopped, to the state of emergency lighting in the instant automatic switching, Emergency time 60 to 90 minutes the second optional.

10. The lamp use electromagnetic induction lamp light source. The light source has the advantages of long service life, high luminous efficiency, light and soft, good shock resistance, long-term use of maintenance free. Lamps as by shock treatment can use strong vibration environment (such as a user requirements of earthquake should indicate in order).
