The invention discloses a novel low-frequency electrodeless lamp with overlong service life. The lamp comprises a bulb and a magnetic core, wherein the bulb and the magnetic core are arranged on a connecting base respectively, an induction coil is wound on the magnetic core, the magnetic core is connected with a core rod, and the core rod is connected with a lamp cap; a thermal insulation protective sleeve made of PA66 and GF materials is sleeved on the magnetic core, and the induction coil is wound outside the thermal insulation protective sleeve; a protective cover made of a PA66 material is sleeved on the connecting base, and a high-frequency ceramic converter is arranged on the core rod; and the high-frequency ceramic converter is connected with the lamp cap. In the invention, the color temperature of the bulb is operated stably, color rendering indexes meet the requirements, the lamp has low color tolerance and low light attenuation, and the service life of the bulb is greatly prolonged at the same time.
Description
technical field [0001] [0002] The invention relates to a novel ultra-long service life low-frequency electrodeless lamp. Background technique [0003] Low-frequency electrodeless lamp bulbs have always been troubled by the development and market application of this product due to the problem of working temperature, unstable color temperature of the bulb, failure to meet the requirements of color rendering index, large color tolerance, and large light decay. Contents of the invention [0004] The purpose of the present invention is to provide a new ultra-long service life low-frequency electrodeless lamp. The present invention has the advantages of stable color temperature of the bulb, satisfactory color rendering index, small color tolerance, small light decay, and greatly improved service life of the bulb. . [0005] In order to achieve the above object, technical scheme of the present invention is: [0006] A new type of ultra-long service life low-frequency elec...
