Halogen tungsten bulb with metallic support
Technical field
The utility model relates to a kind of light source, and particularly a kind of inside is provided with the halogen tungsten bulb of metallic support.
Background technology
Tungsten halogen lamp is because its long-life and the light quality that showed and more and more receive an acclaim than traditional incandescent lamp.In order to realize substituting existing ordinary incandescent lamp with the halogen tungsten incandescent lamp as far as possible simply, while is for the outward appearance of the former of aesthetics or function thereby maintenance conventional incandescent, usually tungsten halogen lamp is designed to following structure: the profile of outline of lamp (being outside bulb shell) and lamp holder is similar to conventional incandescent, and is provided with tungsten halogen lamp in outside bulb shell.Because the volume of tungsten halogen lamp is less, for the outward appearance and the photocurrent versus light intensity that make this lamp close with conventional incandescent, built-in tungsten halogen lamp must be arranged at the position roughly the same with the conventional incandescent filament, and the technological means that is adopted is directly to be utilized as the wire of tungsten halogen lamp power supply as support; But since directly adopt wire do the bulb that supports when reality is used for shaking very sensitivity, in case be subjected to shake can have a strong impact on the lighting effect of lamp and also easy deformation or fracture of wire.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, reliable and stable halogen tungsten bulb with metallic support.
The technical scheme that the utility model adopted is:
Halogen tungsten bulb with metallic support, comprise in lamp holder, outside bulb shell, the outside bulb shell and be provided with tungsten halogen lamp, lamp holder is fixed with stem stem, be provided with metallic support between described tungsten halogen lamp and the stem stem, two of described metallic support is provided with upper and lower intermediate plate, and clamps with stem stem with the clamp plate of tungsten halogen lamp respectively and be connected, a wherein side of the upper clip of metallic support is the T matrix, and the transverse metal edge clamp plate appearance of this T matrix is extended and this clamp plate is clamped; Clamp plate and stem stem respectively draw two conductive wires and welding is fixing respectively.
Further improvement of the utility model, described stem stem is provided with cylinder up, and metallic support encases cylinder.
Further improvement of the utility model, the bipod of described lower clamping piece is S-shaped.
Further improvement of the utility model, described outside bulb shell and the moulding of stem stem sealing by fusing.
The beneficial effects of the utility model are: the metallic support that the tungsten halogen lamp utilization is installed on the stem stem comes positioning supports, and the connected mode of metallic support and tungsten halogen lamp also to utilize the T matrix to hold tightly except direct clip fixing, make the structure of lamp very reliable and stable, the conductive wire that is connected between tungsten halogen lamp and the stem stem does not then need to have guaranteed the normal use of lamp as the main support part.

Embodiment
Referring to figs. 1 through shown in Figure 5, halogen tungsten bulb with metallic support, comprise lamp holder 1, outside bulb shell 2, be provided with tungsten halogen lamp 3 in the outside bulb shell 2, lamp holder 1 is fixed with stem stem 4, be provided with metallic support 5 between tungsten halogen lamp 3 and the stem stem 4, two of metallic support 5 is provided with, lower clamping piece 51,52 and clamp with stem stem 4 with the clamp plate 31 of tungsten halogen lamp and to be connected, that is to say that metallic support 5 utilizes the jag of upper end upper clip 51 that clamp plate 31 is clamped, utilize the jag of lower end lower clamping piece 52 that stem stem 4 is clamped, form more stable support, a wherein side of the upper clip 51 of metallic support 5 is a T matrix 53, the transverse metal limit 54 of this T matrix 53 clamps along the extension of clamp plate 31 appearances and with this clamp plate 31, transverse metal limit 54 is equivalent to clamp plate is encircled or half holding-solid is decided, and has improved the stability of tungsten halogen lamp 3; Clamp plate 31 respectively draws two conductive wires with stem stem 4 and welding is fixing respectively.
Further, more stable in order to make support effect, stem stem 4 is provided with cylinder 41 up, and metallic support 5 encases cylinder 41.
The bipod of lower clamping piece 52 is S-shaped, makes the jag of intermediate plate earlier crooked laterally, turns back and contacts with the surface of stem stem 4, make the clamping better effects if, in addition, stem stem 4 also can be puted forth effort the contact site with this and be designed to concave shape during fabrication, makes the stressed more reasonable of link.
Better for the sealing effectiveness that makes lamp, outside bulb shell 2 can adopt the mode of sealing by fusing moulding to be made into integration with stem stem 4 during fabrication.
Certainly, the utility model is not limited to the above embodiments, is equal to the utility model or the similar techniques scheme also should belong within the protection range of the present utility model.
