Abstract
The invention discloses a bulb which comprises a lamp cap, a glass shell and a support piece, wherein a metal halide discharge lamp used as an illuminant is arranged in the glass shell, a pair of electrodes are led out from a glass core column of the lamp cap, two electrodes in the glass core column of the metal halide discharge lamp are connected with the pair of electrodes led out from the glass core column of the lamp cap in a welding way; the support piece comprises a vertical supporting rod, a horizontal clamping hoop extends out of the bottom of the supporting rod, the clamping hoop is sheathed on the glass core column of the lamp cap, a pair of horizontal clamping pieces extends out of the top of the supporting rod, and the clamping pieces clamp the glass core column of the metal halide discharge lamp. The bulb is characterized in that the support piece is added in the glass shell, and the glass core column in the lamp cap and the glass core column of the metal halide are fixed by the support piece, thereby relieving the pressure of the electrodes, strengthening the bulb structure and prolonging the service life of the bulb.
Description
Technical field
The present invention 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 present invention 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.
Technical scheme of the present invention 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 invention has the beneficial effects as follows of technique scheme:
The present invention 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, makes bulb structure more stable, has prolonged the useful life of bulb.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment of the present invention is following:
Embodiment: a kind of bulb, as shown in Figure 1, comprise lamp holder 1; Glass bulb 2 is provided with the discharge light with metal halide 3 as luminous element in glass bulb 2, lead to pair of electrodes in the glass stem 4 of lamp holder; The pair of electrodes of drawing in two electrodes in the glass stem 5 of discharge light with metal halide and the glass stem 4 of lamp holder is weldingly connected, and also comprises a strutting piece, and described strutting piece comprises the pole 6 of vertical setting; Horizontally disposed clip 7 is extended in the bottom of pole 6; Described clip 7 is enclosed within on the glass stem 4 of lamp holder, and horizontally disposed a pair of intermediate plate 8 is extended at the top of pole 6, and described intermediate plate 8 is clamped the glass stem 5 of discharge light with metal halide.
For the stability of further intensifier electrode, the middle part along continuous straight runs of pole 6 extends a support arm 9, and an electrode of drawing in the glass stem 4 of described support arm 9 and lamp holder is weldingly connected.
