advantages of induction lamp -加拿大28

the induction lighting is a new type of lamp with high lumen efficiency and long life time which meet the global low carbon emission and green lighting requirements. it saves a lot of energy and reduces the maintenance cost significantly. the applications show that the same visual effect is reached when the metal halide lamp or sodium lamp is replaced with lower-watt induction lamp, which result in high power factor, the reduced cable size, the reduced initial investment of the power line and the reduced energy.

the induction lighting has been used in many areas such as the surrounding area of beijing olympic stadiums,t3 terminal building of beijing airport, shanghai bund tunnel, shanghai volkswagon, shanghai general motor, zhengzhou yutong auto, gree electrical appliance, workshops, garage, street and roadway, etc. a large number of applications show that the induction lighting can save more than 40% of energy than that of metal halide or sodium lighting system.the induction system and fixture are designed and manufactured in the same company for high reliability and performance.

advantages of induction lighting：

no electrode with 100k hours operation, maintenance- free, suitable for the high ceiling workshop, sports stadium, roadway and building where are difficult to access;
no flash with soft and gentle lighting, cri more than 80 with good visual effect;
high luminance and low lamp depreciation to meet the lighting requirement within the life time;
instant on and instant hot restrike (vs long delay time of start and restrike of hid lamps).
driven by the electronic ballast with high power factor and low current to reduce the capacity of power distribution equipment(transformer and cable).
the dimmable range from 40% to 100% of rating to work with many intelligent dimmer or control systems without compromising the lighting efficiency and color rendering index to save energy.

unique advantages of induction lighting in the following applications：

difficult accessible area
for example, the tunnel lighting requires no maintenance and long lifetime.the relamping has to take place once one or two years for the sodium lamp while the induction lighting does not need relamping in 10 years.the closing of the tunnel for the maintenance purpose is complicated and troublesome.the induction lighting is good for manufacturing workshop, roadway, high pole, refrigerator room etc where are difficult to access.

high performance lighting requirement area
the foodstuff, automobile assembly, machining, mechanical fabrication, electronic and textile industries requires high color rendering index and no dizzy lighting.the induction lighting is good for workshop, sports stadium, supermarket and public area.

longtime operation requirement and frequent on & off area

instant hot restrike requirement area

community, park, home, architecture

agriculture and hydroponics

classroom and library

solar lighting

high-speed rotation machine workshop

livestock and poultry farm
