1, the high-frequency electrodeless lamp is small in size, and the shape of the bulb changes greatly, so it can be equipped with many lamps. The old lamps can also be used with a little modification, and the light efficiency is higher under the same power. The high-speed particle manifold in the bulb becomes a shield to prevent electromagnetic radiation. However, due to the limitation of light bulb size, the power cannot be very large, and usually the power can only be 200W W W.
2. Low-frequency electrodeless lamp can be made more powerful because of the external coupler, which has a large volume and a very good heat dissipation effect. However, due to its large size, few lamps can be equipped, resulting in a certain lumen loss. In addition, external coupling increases the difficulty of solving EMI.
Insufficient:
1, life of "electrodeless lamp":
The theoretical service life of electrodeless lamps is 60,000 hours, but in fact, if cheaper components, including electrolytic capacitors, are used, the service life of electrodeless lamps is only about16,000 hours in high temperature environment, so we can't just cite the theoretical service life to promote it. In particular, some electrodeless lamps with too low prices will definitely shorten their life.
2, "electrodeless lamp" light effect problem:
The theoretical light efficiency of electrodeless lamp is only 80Lm/W, while the actual product light efficiency is only 65lm/w ... And more energy in the light emitted by electrodeless lamp is concentrated in the visible light near the wavelength of 550nm, so even if the overall luminous flux is not as good as that of sodium lamp, the naked eye impression of electrodeless lamp will be brighter, which makes up for this deficiency.
3. The volume problem of "electrodeless lamp":
Because of the special structure, it is difficult to make electrodeless lamps small, which limits the electrodeless lamps from entering the home improvement market.
Electrodeless lamp is a kind of magnetic energy lamp, a high-tech product developed by comprehensively applying the latest scientific and technological achievements in optics, power electronics, plasma science, magnetic material science and other fields, and a new light source with high luminous efficiency, long life and high color rendering, which represents the future development direction of lighting technology.
Compared with traditional light sources, electrodeless lamps are named because they have no obvious electrodes.
An electrodeless lamp consists of a high-frequency generator, a coupler and a bulb. The electromagnetic field of the high-frequency generator is inductively coupled into the lamp, so that the gas in the bulb is avalanche ionized to form plasma. When atoms excited by plasma return to the ground state, they will radiate ultraviolet rays. The fluorescent powder on the inner wall of the bulb is excited by ultraviolet rays to generate visible light.
