Abstract
The utility model discloses a sealing structure of a lamp, comprising a lamp body and a face plate, wherein a sealing area between the lamp body and the face plate is provided with a self-adhesive layer. The sealing structure of the lamp has the advantages of simple structure, convenient construction, satisfaction of the requirements for rapid mounting and maintenance, good sealing as the sealing structure of the lamp has good sealing and can fully fill the sealing area, as well as adhesion, elasticity, realization of micro-displacement durable effectiveness of the sealing function and wide application range, and is especially suitable for waterproof lamps such as fountain lamps, landscape lamps and the like.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction of light fixture.
Background technology
Development along with the light fixture technology, the lamp applications place is more and more, sealing structure to light fixture requires more and more higher, particularly outdoor lights, lamp etc. is especially strict to seal request under water, if seal failure, water or steam will enter lamp interior, influence the lamp luminescence effect or cause short circuit, especially emerging LED light fixture, components and parts such as its internal circuit chip will be damaged in short circuit, so the Sealing Technology of light fixture directly affects the safe in utilization and life-span of light fixture.
Common light fitting sealing structure mainly contains following several:
1, adopts the seal gasket mode to seal, promptly carry out special seal gasket form design according to concrete fitting structure in advance, adopt mode moulding such as molded vulcanization, make special-purpose solid-state seal gasket.This structure has than reliable sealing effect, but its shortcoming is to need to manufacture and design at concrete structure, and versatility is not strong; When the mating surface of former design hermetically-sealed construction because of processing the phenomenon that occurs seal failure when reason such as bad causes fit clearance to change easily.In transportation, installation or use, also cause seal failure when being answered masterpiece power to cause seal clearance generation micro-strain easily when light fixture assembling back simultaneously, this this stress comprises because of expanding with heat and contract with cold of causing of the cold and hot variation that takes place in the environment for use of light fixture and the process, the grinding pressure that pavement light in use is subjected to, the foundation construction of lamp installation deform etc., and these stress can not be overcome under present engineering state fully.
2, adopt seal glass glue mode to seal.Seal glass glue mode can be finished the setting of hermetically-sealed construction by the cast-in-site mode, overcome seal gasket and need carry out the problem that particular design is made, realized versatility, be difficult to guarantee evenly but shortcoming is the sealing applying glue at concrete structure, it is consuming time that operation is just done in applying glue, and efficient is slow; Existing glass cement resistance to ag(e)ing is poor; A little less than the resist displacement ability, therefore cause the phenomenon that causes seal failure because of long-term stress effect easily simultaneously.
3, adopt the hermetically-sealed construction of whole embedding fluid sealant, its sealing effectiveness is best, but has the shortcoming that glue consumption is big, cost is high, and the applying glue curing process is consuming time, later stage light fixture components and parts need excavate former pouring when maintenance fluid sealant just can carry out, and needs embedding fluid sealant again after maintenance.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, installation and easy to maintenance and have a hermetically-sealed construction of the light fixture of excellent sealing effect.
Technical solution of the present utility model is: a kind of hermetically-sealed construction of light fixture, comprise light fitting body and panel, and on the sealing area between described light fitting body and the panel, be provided with and do not do the tack glue-line.
Not dried self-adhesive glue be a kind of be the jelly of main material with butyl rubber, it has excellent air-tightness, resistance to ag(e)ing is good, the life-span is long, has quick strong bond function and sealing function lastingly simultaneously.On the sealing area between light fitting body and the panel, be provided with and do not do the tack glue-line, can realize the preliminary connection between light fixture and the panel by the viscosity of this glue-line self, easy construction, can satisfy the demand of quick installation and maintenance, and in extruding or stress effect following time, do not do the tack glue-line and itself have the viscosity of holding and elastic displacement function, can follow the relative microdisplacement that takes place between light fitting body and the panel and produce synchronous shift, has sealing function microdisplacement lasting effect, fully fill sealing area, the phenomenon of seal failure can not appear with STRESS VARIATION in its better tightness.
Described dried tack glue-line is identical with described sealing area area.Can not do the tack glue-line accordingly according to the cutting of sealing area area, simplify construction procedure, can guarantee enough sealing contact surfaces simultaneously, further improve sealing effectiveness.
The utility model has the advantages that: simple in structure, easy construction can be satisfied the demand of quick installation and maintenance, and himself air-tightness is good simultaneously, can fully fill sealing area, good airproof performance.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment;
1, light fitting body, 2, panel, 3, sealing area, 4, do not do the tack glue-line.
The specific embodiment
Embodiment:
Consult Fig. 1, a kind of hermetically-sealed construction of light fixture comprises light fitting body 1 and panel 2, is provided with sealing area 3 between light fitting body 1 and panel 2, is respectively equipped with the not dried tack glue-line 4 identical with its area on sealing zone 3.
In the present embodiment, this is not done the tack glue-line and uses butyl rubber to be main colloid, for example adopt commercially available SCH16A sealing joint strip, the SCB03 sealing joint strip, or the extremely viscous adhesive waterproof tape of Shanghai Rui Bang Industrial Co., Ltd. production, and the Butylband butyl waterproof sealing putty of DAFA production etc., size according to sealing area 3, cut the tack glue-line of not doing of the same area, be placed on the sealing area of light fitting body, cover panel then, apply certain pressure and keep short time (as 1 a second) recession except that pressure, just the disposable bonding fixing seal operation of finishing panel.Certainly, in order to guarantee enough bonding strengths, tightening members such as screw can be set, between panel and body so that more firm connection effect to be provided.Correspondingly directly open panel in when maintenance, just can realize the replacing of light fixture, when resealing, look the viscosity of not doing the tack glue-line, the mode of taking not change or change the novel sealing material reseals.
Above-listed detailed description is specifying at one of the utility model possible embodiments, this embodiment is not in order to limit claim of the present utility model, allly do not break away from the equivalence that the utility model does and implement or change, all should be contained in the claim of this case.
Claims (2)
1. the hermetically-sealed construction of a light fixture comprises light fitting body and panel, it is characterized in that: be provided with on the sealing area between described light fitting body and the panel and do not do the tack glue-line.
2. the hermetically-sealed construction of a kind of light fixture according to claim 1 is characterized in that: described not do the tack glue-line identical with described sealing area area.
