Abstract
The utility model discloses a ceramic reflecting cover type halogen tungsten lamp bulb which is used for illumination and comprises a halogen tungsten lamp tube, a metal lamp cap and a glass cover. A ceramic reflecting cover, the inner surface of which is coated with a reflecting layer, is arranged between the glass cover and the metal lamp cap. The ceramic reflecting cover adopted by the utility model bears high temperature and thermal shock. After the inner surface of the ceramic reflecting cover is coated with the reflecting layer, light generated by a luminous body converges into a luminous beam and has obvious directional illumination effect. Thus, the utility model is a novel directional illumination light source used for outdoor illumination devices.
Description
The utility model relates to the electric light source technology field, particularly a kind of illuminating ceramic reflecting cover type tungsto-halide bulb.
Existing reflection-type halogen tungsten bulb, its reflector all adopt the glass compacting to form.Because its internal stress is bigger, the thermal shock resistance properties that adds glass material itself is poor, when temperature generation acute variation, vitreum inside also will produce stress, both can make the reflector housing made with glass break because of the existence of internal stress can produce at any time together or be broken, thereby have influence on the life-span and the fail safe of bulb.
The purpose of this utility model is to provide a kind of simple in structure, high temperature resistant and ceramic reflecting cover type tungsto-halide bulb that confession indoor and outdoor illumination device directional lighting that thermal shock resistance properties is superior is used.
The utility model is achieved in that a kind of ceramic reflecting cover type tungsto-halide bulb, comprise halogen tungsten fluorescent tube, glass cover, metallic lamp holder, lead-out wire, a reflector is housed between metallic lamp holder and glass cover, the halogen tungsten fluorescent tube is contained in the reflector, reflector is made of housing and the surperficial within it reflector that plates, and housing is made by the thin-walled pottery.
The inside and outside surface configuration in described reflector housing top is the rotation parabolic type, and its upper surface circumference has groove, and upper surface overall diameter scope is at φ 50-φ 100mm, and lower housing portion is cylindrical.The reflector that reflector housing upper inside surface is plated is aluminium film or saturating ultrared multilayer dielectric film.The halogen tungsten fluorescent tube is to adopt cylindricality tungsten halogen lamp or single-ended tungsten halogen lamp.
Be equipped with a fuse in general metallic lamp holder, this fuse is connected on the current supply circuit of bulb.The fuse material adopts constantan wire.
Reflector housing of the present utility model is owing to be to adopt the thin-walled ceramic material to make, so its thermal shock resistance properties is superior, can bear violent variations in temperature and can not produce tangible internal stress, make this bulb in use can not occur breaking and broken phenomenon, have long life-span and good safety in utilization.
At its reflector housing upper inside surface plated aluminum film or saturating ultrared multilayer dielectric film as reflection layer, make light that this bulb sends after reflective layer reflects, converge at the place ahead, form a branch of light, the angle of its light beam can reach with the parabolical shape of change reflector shell inner surface by the position that focuses of regulating bulb.
The utility model luminous element adopts the halogen tungsten fluorescent tube of function admirable, and its life-span and light efficiency be not only than ordinary incandescent lamp height, and more superior is, light is logical stable, light decay moves back seldom, still keep initial luminous flux until dying of old age, improved illuminating effect, saved the energy greater than more than 95%.Because the reflector housing adopts the thin-walled pottery to make, and is not only high temperature resistant, and the acute variation of heatproof degree again, its intensity is also good simultaneously, has more firm, reliable and safe performance than the reflector housing that uses the glass manufacturing.After reflector housing upper inside surface plated reflection layer, the optical convergence that luminous element is sent became a light beams, demonstrated the effect of its directional lighting more, was a kind of directional lighting light source of brand-new type.In addition, this bulb also have the life-span long, safety in utilization good, energy-conservation and good looking appearance, stylish advantage, help being widely used in the indoor and outdoor directional lighting device.
Structural representation when Fig. 1 is the utility model employing screwed socket;
Fig. 2 is a reflector structure cutaway view shown in Figure 1.
By following embodiment the utility model is further elaborated.
With reference to Fig. 1, shown in Figure 2, the metallic lamp holder of present embodiment (4) is selected the E27 screwed socket for use.Halogen tungsten fluorescent tube (2) is selected single-ended tungsten halogen lamp for use, and its power is 75W, and voltage is 240V.The molybdenum lead-out wire of halogen tungsten fluorescent tube (2) is held back 4-5mm length, and the nickel wire of φ a 0.6 * 40mm of end spot welding of a lead-out wire therein, fuse (5) made from the long constantan wire of φ 0.18 * 40mm of the end spot welding of another root molybdenum lead-out wire.The housing (7) of reflector (1) is made by the thin-walled pottery, and the inside and outside surface configuration in its top is the rotation parabolic type, and the upper surface circumference has groove, is used to install and fix glass cover (3).Housing (7) bottom is cylindrical, and its lateral wall has a groove, is used to bury the fuse (5) of drawing.Reflector housing (7) upper inside surface plates layer of metal aluminium film, forms a reflector (8).Halogen tungsten fluorescent tube (2) is packed in the reflector (1), firmly fixed with the lamp holder mudding.Metallic lamp holder (4) is inserted in reflector (1) bottom, and lead-out wire (6) is worn out from the aperture of metallic lamp holder (4) bottom.Fuse (5) is extracted from the groove of metallic lamp holder (4) and reflector housing (7).Secure metallic lamp holder (4) and reflector (1) bottom fixing with lamp holder mud.Then, glass cover (3) is covered in the groove of reflector (1) upper surface, blended rubber water secures it fixing.At last, use the soldering jail on the electric contact of metallic lamp holder (4) bottom lead-out wire (6) end,, promptly become a ceramic reflecting cover type tungsto-halide bulb the extension of fuse (5) upper edge of soldering jail in metallic lamp holder (4).
The power bracket of the halogen tungsten bulb that the utility model can be produced is 50-250W, and its operating voltage grade is 12V, 24V, 36V, 110-130V, 220-240V.
