Belong to the new green light source in twenty-first Century - LED lamp PK electrodeless lamp

From the history of the development of electric light source, high frequency electrodeless lamp and LED lamp belong to the fourth generation of electric light source, the former belongs to the arc discharge, the latter is solid. Make a comparison between the performance of high frequency electrodeless lamp and LED lamp. It can be seen from the table (1) that the high frequency electrodeless lamp and LED are the same as the green electric light source, they have many similar characteristics, but in the field of application of each have biased. LED lamp is mainly used for landscape decoration, subtitle advertising lighting, single body power is small; and high frequency electrodeless lamp mainly in the workplace and outdoor public lighting, monomer power. In the future, these two new technologies will continue to develop on the basis of their luminous mechanism, and gradually replace most of the traditional lighting electric light source.

Safety safety safety should be with lighting engineering display field ealong applications other than the display outside the field of lighting to replace incandescent lamp fluorescent lamp

The electrode material sputtering effect of high frequency electrodeless lamp fluorescent lamp is not like that, so light is very slow, so long life guarantee. Another principle of change is: working frequency of fluorescent lamp is low, when the sine wave voltage is zero, there is a part of the positive ion and electron ionization compound, the lamp extinguished instantly (human awareness out), in a cycle of fluorescent lamp to start the two time, the light output decreased. High frequency electrodeless lamp is using high frequency electromagnetic field frequency of 2.5 3.0MHz excitation light, as long as the excitation energy balance, light can be normal light, there is no problem of zero voltage extinction, the effect of light is about 20% higher than the fluorescent lamp, the energy-saving effect is obvious. In addition, the spectral distribution of high frequency electrodeless lamp in visible light, a higher proportion, reached about 80%, the wavelength is more abundant in human visual sensitivity area spectrum before and after 555nm so, under the same illumination, high frequency electrodeless lamp with good visual effect to other electric light source.
