Abstract

The invention discloses a high-frequency electrodeless lamp, composed of a high frequency generator (1), a lamp (2), a coupler (3) and a lamp socket (4), wherein the lamp (2) is composed of a glass bulb (21) coated with a phosphor layer (22), a glass inner tube (25) with an exhaust tube (23), and solid-state mercury (24), and the coupler (3) is composed of a heat-radiation copper rod (31), a coil (32) and a magnetic core (33). In the invention, nickel-zinc ferrite is adopted as component materials of the magnetic core (33), thereby effectively avoiding disadvantages that during working the high-frequency electrodeless lamp is high in temperature, great in energy losses, complex in processing, and decreasing in luminous efficiency. Thus, energy can be saved, luminous efficiency of the electrodeless lamp is increased, and span of the lamp is prolonged.

Description

technical field [0001] The invention relates to an illumination light source, in particular to a high-frequency electrodeless lamp. Background technique [0002] As a kind of lighting source, high-frequency electrodeless lamp is widely used in shopping malls, large buildings, outdoor lighting, especially landscape lighting. The high-frequency electrodeless lamp is a high-tech new light source integrating the latest electronic power-saving technology and electric light source technology. It does not need a filament, but uses a magnetic field to excite the gas to discharge and emit light. It has many advantages such as high efficiency, energy saving, green environmental protection, and long life. The high-frequency electrodeless lamp is composed of a high-frequency generator, a coupler, a bulb, and a lamp holder. When a high-frequency current passes through the coupler, a high-frequency electromagnetic field is generated, and the changing magnetic field generates an electric f...
