Abstract
The utility model discloses a bulb which comprises a lamp holder and a glass casing, wherein a metal halide discharging lamp serving as a luminous body is arranged in the glass casing, a pair of electrodes is led out of a glass core column of the lamp holder, and two electrodes in a glass core column of the metal halide discharging lamp are connected with the pair of the electrodes led out of the glass core column of the lamp holder in welding mode. The bulb further comprises a support member which comprises a vertically-arranged support rod, wherein a horizontally-arranged clamping hoop extends out of the bottom of the support rod and is sleeved on the glass core column of the lamp holder, the top portion of the support rod extends out to be provided with a pair of horizontally-arranged clamping pieces which clamp the glass core column of the metal halide discharging lamp. The support member is added in the glass casing of the bulb, and the glass core column in the lamp holder and the glass core column in the metal halide discharging lamp are fixed through the support member, so that pressure of the electrodes is reduced, the structure of the bulb is stable, and service life of the bulb is prolonged.
Description
Technical field
The utility model relates to a kind of bulb.
Background technology
Metal halogen lamp is the third generation green illumination light source that the world today emerges after incandescent lamp, Halogen lamp LED; With advantages such as light efficiency is high, color rendering is good, long service life; Not only become the first-selection of light sources such as high-grade car, rear-projection TV, also can be widely used in fields such as military affairs, exploration, underwater operation, open-air search and rescue.Compare with ordinary incandescent lamp, the Metal halogen lamp energy-saving effect is surprising, and its luminous efficiency is higher, and the market space is huge.
Common Metal halogen lamp comprises lamp holder, and glass bulb is provided with the discharge light with metal halide as luminous element in glass bulb; Lead to pair of electrodes in the glass stem of lamp holder; The pair of electrodes of drawing in two electrodes in the discharge light with metal halide glass stem and the glass stem of lamp holder is weldingly connected, and discharge light with metal halide mainly is to support by electrode, and electrode welds together; So weld ruptures easily in the course of time, cause and scrap.
Summary of the invention
The utility model has overcome the deficiency that exists in the above-mentioned prior art; A kind of reliable and stable bulb is provided; This bulb has increased strutting piece in glass bulb, the glass stem of glass stem in the lamp holder and metal halide is fixed up through strutting piece, has alleviated the pressure of electrode; Make bulb structure more stable, prolonged the useful life of bulb.
The technical scheme of the utility model is achieved in that
A kind of bulb comprises lamp holder, glass bulb; In glass bulb, be provided with the discharge light with metal halide as luminous element, lead to pair of electrodes in the glass stem of lamp holder, the pair of electrodes of drawing in two electrodes in the discharge light with metal halide glass stem and the glass stem of lamp holder is weldingly connected; Also comprise a strutting piece; Described strutting piece comprises the pole of vertical setting, and horizontally disposed clip is extended in the bottom of pole, and described hoop sleeve is on the glass stem of lamp holder; Horizontally disposed a pair of intermediate plate is extended at the top of pole, and described intermediate plate is clamped the glass stem of discharge light with metal halide.
For further fixed electrode, as preferably, the middle part along continuous straight runs of pole extends a support arm, and an electrode of drawing in the glass stem of described support arm and lamp holder is weldingly connected.
Adopted the beneficial effect of the utility model of technique scheme to be:
The utility model is in glass bulb, to have increased strutting piece, and the glass stem of glass stem in the lamp holder and metal halide is fixed up through strutting piece, has alleviated the pressure of electrode, makes bulb structure more stable, has prolonged the useful life of bulb.
