Description
Technical field
The utility model relates to field of light fittings, particularly a kind of waterproof head lamp.
Background technology
Environment uses head lamp through mine of being everlasting, culvert, outdoor environment, sea etc., working environment is very moist, even has water droplet, and battery case, charging hole, switch hole, wire hole etc. are very easily then intake, damaging inner member causes head lamp to lose efficacy, and have impact on the use of workman.Especially easily intake between lampshade and housing, sealing becomes the technical barrier that those skilled in the art face for a long time.At present, the means solved this technical problem in prior art all adopt and are threaded, and be unable to do without sealing ring.This technology not only complex structure but also waterproof effect can not reach absolutely.
Utility model content
In view of the above, the utility model is necessary to provide a kind of structure waterproof head lamp that is simple, effectively waterproof.
A kind of waterproof head lamp, comprise battery component, housing, diffuser, emitting led wick, described housing comprises heavy caliber end and small-caliber end, small-caliber end is closed and is offered an aperture, and heavy caliber end is open, and described battery component is arranged on the small-caliber end of housing, described diffuser is that transparent material is made, hermetic seal is fixedly installed on housing heavy caliber end, and described emitting led wick is embedded in housing, is connected through aperture by electric wire with battery component.
Further, described lamp housing heavy caliber end offers scrobicular ring, is correspondingly formed with flange, and this scrobicular ring and flange are used for fixing diffuser.
Further, the connecting ring that described diffuser comprises light transmission piece and formed around light transmission piece, the internal diameter of described connecting ring is greater than described flange outside diameter, and described connecting ring width is suitable with scrobicular ring width, connecting ring inwall is close to by flange outer sides wall, and diffuser is fixed in hermetic seal.
Further, in described housing, reflection shield is set, or in housing, is coated with one deck reflector layer.
Further, adopt consolidation between described battery component and housing or removably connect.
Further, described emitting led wick is closed by hermetically-sealed construction through aperture and battery component junction by electric wire.
Compared to prior art, waterproof head lamp of the present utility model, direct frit seal between its diffuser and described lamp housing, greatly improve water-tight performance, service life extends greatly.In addition, structure is simple, adopts laser welded seal to be connected between described diffuser with described lamp housing, decrease material consumption when being screwed connection, housing needing the part matched with screw, reduce difficulty of processing, decrease manufacturing procedure, greatly reduce production and processing cost; Reduce light fixture volume simultaneously, alleviate product weight, installation is more prone to.
Accompanying drawing explanation
Fig. 1 is the waterproof head lamp stereochemical structure explosive view of the utility model preferred embodiment, meaning electric wire not shown in the figures and emitting led wick;
Fig. 2 is the waterproof head lamp three-dimensional structure diagram of the utility model preferred embodiment.
Detailed description of the invention
In order to elaborate the technical scheme that the utility model is taked for reaching predetermined technique object, below in conjunction with the accompanying drawing in the utility model embodiment, carry out clear to the technical scheme in the utility model embodiment, intactly describe, obviously, described embodiment is only section Example of the present utility model, instead of whole embodiments, and, under the prerequisite not paying creative work, technological means in embodiment of the present utility model or technical characteristic can be replaced, below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Refer to Fig. 1, a kind of waterproof head lamp 100 of the utility model preferred embodiment, comprise battery component 10, housing 20, diffuser 30, emitting led wick (not shown).The roughly tapered shape of described housing 20, comprises heavy caliber end and small-caliber end, and small-caliber end is closed and offered an aperture, and heavy caliber end is open.Described battery component 10 is arranged on the small-caliber end of housing 10.Described diffuser 30 is made for transparent material, and hermetic seal is fixedly installed on housing 20 heavy caliber end.Described emitting led wick is embedded in housing 20, is connected through aperture by electric wire with battery component 10.
Described housing 20 heavy caliber end offers scrobicular ring 21, is correspondingly formed with flange 22.This scrobicular ring 21 and flange 22 are for fixing diffuser 30.
The connecting ring 32 that described diffuser 30 comprises light transmission piece 31 and formed around light transmission piece.The internal diameter of described connecting ring is greater than described flange outside diameter.Described connecting ring 32 width is suitable with scrobicular ring 21 width.During installation, flange 22 lateral wall is close to connecting ring 32 inwall, herein airtight by laser welding, thus fixing diffuser 30.
Further, in described housing 20, reflection shield is set, also can be coated with one deck reflector layer in housing 20.
In addition, adopt consolidation between described battery component 10 and housing 20 or removably connect.
In addition, guarantee the reliability of waterproof, described emitting led wick carries out Seal treatment through aperture and battery component 10 junction by hermetically-sealed construction 40 by electric wire.
Waterproof head lamp 100 of the present utility model, direct frit seal between its diffuser 30 and described housing 20, greatly improve water-tight performance, service life extends greatly.In addition, structure is simple, adopts laser welded seal to be connected between described diffuser 30 with described housing 20, decrease material consumption when being screwed connection, housing needing the part matched with screw, reduce difficulty of processing, decrease manufacturing procedure, greatly reduce production and processing cost; Reduce light fixture volume simultaneously, alleviate product weight, installation is more prone to.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solutions of the utility model content, according to technical spirit of the present utility model, within spirit of the present utility model and principle, to any simple amendment that above embodiment is done, equivalent replacement and improvement etc., within the protection domain all still belonging to technical solutions of the utility model.
