Abstract
The utility model relates to a stem of a light-gathering source lamp bulb, which comprises a lamp casing, a tungsten filament and a stem, wherein the stem is formed by that two leading wires which are different in height are solidified to form a long and a short pins which are oppositely arranged. A plurality of tungsten filaments which are buckled at intervals are arranged between the two opposite leading wires which are different in height, and the front end of the long leading wire is bent to form an inclined bending angle of which the vertex is abutted with the end of the lamp casing. Constant spacing is formed between the stem and the lamp casing, and the tungsten filaments of the stem send out stable light in the constant spacing; the lamp casing is in the shape of a calabash body from top to bottom and is utilized to obtain two brilliant light sources which have light rings with different focal length. Light passes through a glittering and translucent convex circle at the front top end of the lamp casing to achieve the practical effect of gathering light and emitting centralized and gathered light.
Description
The utility model relates to lighting device, relates in particular to a kind of optically focused source bulb core-column.
Commonly use the light source of lamp series bulb, must rely on a stem stem to shore tungsten filament and obtain the illuminated light effect in its bulb, the composition of this stem stem and tungsten filament, be to make two interval seal wires solidify a pearl body and form opposed, so that two parallel conductive wire foot upper end snapping tungsten filaments, this structure only has the illumination effect of the single tungsten filament of stem stem; In addition, uncontrollable during fabrication its fixing spacing of stem stem and lamp housing, so it is near excessively that the distance of tungsten filament and lamp housing has, the distance that has is drawn very greatly, can't concentrate when the light that tungsten filament is sent penetrates by lamp housing to be astigmatic shape, and the composition of stem stem and lamp housing often has direct conflict lamp housing bottom to cause the tungsten filament pressurized to twist the unfavorable condition of being entangled with.Therefore its illumination effect does not all meet practical requirement with manufacturing two aspects.
Main purpose of the present utility model is to provide a kind of optically focused source bulb core-column, the longer seal wire front end of its stem stem bends a knuckle, this knuckle front end conflict lamp housing, so that stem stem and lamp housing form a constant spacing, make the tungsten filament of stem stem end under fixed range, send stable light, the beautiful light source of borrowing the lamp housing that is the cucurbit body up and down to obtain two sections different focal irradiation apertures, and by the sparkling and crystal-clear thorough dome in the preceding top of lamp housing makes light-ray condensing and penetrates concentrated polymerization light projector body.
A time purpose of the present utility model is to provide a kind of optically focused source bulb core-column, by the knuckle of stem stem front end bending, makes tungsten filament unlikelyly be hit distortion, intertwine, and improves the quality of products greatly.
Another purpose of the present utility model is to provide a kind of optically focused source bulb core-column, the knuckle portion front end of its stem stem front end bending contacts lamp housing, make tungsten filament and lamp housing body inside maintain constant spacing, so that the unlikely error that produces focal length point that moves forward and backward of tungsten filament, and form the polymerization light projector body that can launch fixed focal length light.
The purpose of this utility model is realized by following technical scheme.
The utility model optically focused source bulb core-column, comprise lamp housing, tungsten filament and stem stem, its improvements are, described stem stem is frozen into an opposed length by two not reciprocity seal wires of height and short two lamp bases constitute, between relative length seal wire, be provided with several tungsten filaments of spacing snapping, long seal wire front end is bent into an inclination knuckle, and contact touches the lamp housing end, makes stem stem and lamp housing form a constant spacing.The stem stem tungsten filament sends under the light of stability at constant spacing, borrow the lamp housing that is the cucurbit body up and down to obtain the beautiful light source of two sections different focal irradiation apertures, and, reach the practical function that light-ray condensing and ejaculation are concentrated by the sparkling and crystal-clear thorough dome in the preceding top of lamp housing.
Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Fig. 1 forms the perspective view of lamp string for the utility model
Fig. 2 forms the enforcement view of concentrating polymerization light projector body for the utility model
Fig. 3 is a side schematic view shown in Figure 2
Fig. 4 shows for the enforcement state that the utility model forms two sections different focal radiation source
Intention
Fig. 5 is a side schematic view shown in Figure 4
Consult Fig. 1 to shown in Figure 5, the utility model optically focused source bulb core-column, comprise lamp housing, tungsten filament and stem stem, its improvements are, described stem stem is by two seal wires 6 that height is not reciprocity, 66, be frozen into opposed one long and short two a lamp base seal wires formation with hot melt glass liquid 666, between relative length seal wire, be provided with several tungsten filaments 8 of spacing snapping, long seal wire 66 front ends are bent into an inclination knuckle 68, so that contact is touched the lamp housing end during with knuckle shape front end combination lamp housing 9 inside, make stem stem and lamp housing form a constant spacing, so that stem stem end snapping tungsten filament section is apart from set up 9A up and down separately with lamp housing, 9B Pear-Shaped lamp housing body is consistent reciprocity level, and then the stem stem tungsten filament is sent at constant spacing stablize under the light, can obtain the beautiful light source of two sections different focal irradiation aperture by cucurbit body circle lamp housing body, and close distance by the lamp housing front end admittedly through stem stem inclination knuckle shape contact and make the preceding top of lamp housing that sparkling and crystal-clear thorough dome 99 collected light are set, reach the whole optically focused source practical function that penetrates the polymerization light projector body of concentrating.
In sum, the utility model optically focused source bulb core-column, overall construction design is reasonable, overcomes the defective of traditional product, and the result of use ideal reaches the desired design purpose.
