The radiating head is composed of radiating fins, wherein the radiating fins are radially distributed outwardly from the center of the radiating head. The center of the radiating head is provided with a tubular cavity used for the power coupler to pass through. According to the technical scheme of the utility model, the electrodeless lamp is good in radiating effect, and the long-time normal operation of the bulb is ensured.

Description

A kind of Non-polarized lamp

Technical field

The utility model relates to Non-polarized lamp field, particularly a kind of Non-polarized lamp.

Background technology

Non-polarized lamp is the abbreviation of high-frequency plasma electric discharge Non-polarized lamp, being the new high-tech product that the up-to-date scientific and technological achievements in field such as integrated application optics, power electronics, plasma, magnetic material are developed out, is a kind of new type light source that represents the high light efficiency of lighting technology, long-life, high-color rendering future thrust.

We know the sodium vapor lamp of high light efficiency, and the heat of sending when 170W makes quartz burner temperature even higher up to 400 ℃, but quartz ampoule can work long hours above at 700 ℃, so high temperature is not very large on its life-span impact.Although and the heat of Non-polarized lamp only has 100 more in when work and spends, the components and parts of its electric ballast belong to heat than more sensitive parts, thus must effectively bulb temperature and ballast be kept apart, otherwise can affect its life-span.Therefore the heat dissipation problem in Non-polarized lamp use procedure is a direction of Non-polarized lamp seeking breakthrough always.

Utility model content

It is good that the purpose of this utility model is to provide a kind of thermal diffusivity, the simple Non-polarized lamp of mounting structure.

Realizing the technical solution of the utility model is: the utlity model has bulb, power coupler, link and screw socket; Described bulb center is provided with coupler installation cavity, and one end of power coupler is connected with screw socket and passes link and stretch in coupler installation cavity; The openend of described bulb is fixedly connected with the upper end of link, and the lower end of link is fixedly connected with screw socket; Described link comprises that outside bag establishes chlamydate heat dissipation head, aluminium matter connecting ring; The openend of described bulb is connected with aluminium matter connecting ring, and aluminium matter connecting ring is connected with heat dissipation head; The fin that described heat dissipation head is outwards radially distributed by center forms, and its center is provided with the tubular cavity that can pass for power coupler; On each fin of described heat dissipation head, be equipped with the secondary fin of outside radiation.

On the shell that the outside bag of above-mentioned heat dissipation head is established, be evenly provided with microscler louvre.

The utlity model has positive effect: (1) the utility model is provided with heat dissipation head in power coupler outside, be convenient to heat radiation; (2) heat dissipation head cross section of the present utility model is flakes, its radiating effect change, the useful life of improving bulb; (3) the utility model is provided with shell in heat dissipation head outside, has increased aesthetic property and fail safe.
