Induction lamps and LED lights compared to LED better, and LED lights are more cost-effective.
1, luminous efficacy: induction lamp theoretical luminous efficacy of only 80Lm / W, and the actual product luminous efficacy of only 65Lm / W, and energy-saving lamps are comparable to, and can not be compared with (sodium / metal halide lamp luminous efficacy of 110Lm / W - 120Lm / W) can not be compared with the LED lamps (LED lamp efficacy of 120lm / W or more).
2, induction lamp "cost issues:
Because of the induction lamp actual life is difficult to reach the theoretical life, and the induction lamp "electronic ballast" cost is high, a 185W induction lamp once the damage, the whole lamp replacement, the cost of up to 500 yuan / only above.
3, induction lamp "electromagnetic interference and space electromagnetic radiation:
Induction lamp is relying on "electromagnetic wave or microwave" work, its microwave generator sends out ultra-high-power electromagnetic wave, the propagation distance can be up to 1,000 kilometers, and the proximity is an insoluble "interference source". "source of interference", a lot of information and manufacturers say, electromagnetic interference as early as 2004 on the solution, but in 2008, China's Shenzhen Airport occurred "induction lamp interference with aviation navigation systems," a serious accident.
4, induction lamp "standardization issues:
Since the induction lamp is still in the free trial and testing stage at the street lamp, there is still a certain distance from the market acceptance, at present, each enterprise quotes its own standard, there is no national unified standard, the traditional lamps and lanterns distribution can not be used in the induction lamp, the interface compatibility is poor, and the lamp can not be used for the induction lamp, the interface compatibility is poor. The traditional lamp light distribution can not be used for "induction lamp", poor interface compatibility, ballast replacement difficulties, these problems are not solved, product maintenance will be very difficult. Induction lamp glare is much heavier than metal halide lamps, also leading to induction lamps are difficult to become a mainstream light source.
What is induction lamp
Induction lamp is a kind of magnetic energy lamp, is a comprehensive application of optics, power electronics, plasma, magnetic materials and other fields of the latest scientific and technological achievements developed out of the high-tech products, is a new type of light source on behalf of the future direction of the development of lighting technology with high luminous efficacy, long service life and high color rendering.
Compared with the traditional light source, induction lamp is named because it has no obvious electrode.
Two, what is the LED lamp
LED lamp is a piece of electroluminescent semiconductor material chip, with silver glue or white glue cured to the bracket, and then silver or gold wire to connect the chip and the circuit board, surrounded by epoxy resin sealing, to play a role in protecting the internal core wire, and finally install the shell, so the LED lamp has a good anti-vibration performance.
Principle: LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device capable of converting electrical energy into visible light, which can be directly converted into light. the heart of the LED is a semiconductor wafer, the wafer is attached to a bracket at one end, one end of the negative terminal, the other end of the connection to the power supply of the positive electrode, so that the entire wafer was epoxy resin encapsulation.
