Abstract
The waterproof construction of this light fixture is the positive and negative pressure solving lamp interior generation, for foothold with air a certain amount of in lamp housing material, annular seal space and variations in temperature, particularly variations in temperature causes the air in chamber and expands with heat and contract with cold, the positive and negative alternative pressure that lamp housing is produced and the miniature deformation of lamp housing material, cause the seal failure of traditional approach, its technical scheme solved is that the seal cavity of lamp body can be changed.Place air bag or barrier film at annular seal space opening part and can free-extension, lamp chamber changes volume by air bag or barrier film.Seal is not subject to the pressure inside and outside lamp, makes the external and internal pressure of lamp body be balance.Thus reduce the requirement of lamp housing mechanical property and encapsulant are subject to the positive and negative pressure in lamp and are reduced, extend the shell of light fixture and the service time of encapsulant, what lamp interior did not have moisture content in outside air enters in lamp chamber, extends the service life of light fixture.
Description
Technical field
This light fixture waterproof construction belongs to: the electrical equipment in electronic information technical field and electrical engineering technology type; Relate to classification number: F21 illuminating industry
Technical background
The waterproof of the most of light fixture in current outdoor has two kinds of modes: 1, that glass or other light transmissive material and lamp housing glue and sealing gasket carry out water-tight, having a common feature to be exactly its component is rigid material, the first makes it produce stress by rigid structural member crush seal pad, stress after being squeezed by it keeps sealing, but As time goes on, the stress produced by extruding can slowly disappear, add the on and off of light fixture inner light source, light fixture heating during bright light, accelerate material stress release, air simultaneously in annular seal space expands and produces malleation, otherwise during bright light, temperature decline does not produce negative pressure, the process that long-time positive/negative pressure repeatedly replaces, cause losing sealing property, it two is seal by the glue that partly flows (as glass cement), and the process that also can be replaced by the positive/negative pressure of lamp interior is to destroying.2, seal completely to the transparent silica gel in light source place, thisly can play sealing effectiveness but time one long glue will turn to be yellow, affect optical property and production cost is higher, complex procedures.Current most of outdoor lamp uses the very short time just have into water or form mist and the globule, thus affects luminous mass and the life-span of light fixture.
Utility model content
The waterproof construction of this light fixture solves: the positive and negative pressure that lamp interior produces, for foothold with air a certain amount of in lamp housing material, annular seal space and variations in temperature, particularly variations in temperature the air in chamber caused expand with heat and contract with cold (by gas physical the subject of knowledge and the object of knowledge surely namely temperature raise volume and become large, if constancy of volume, pressure raises, vice versa) to the positive and negative alternative pressure of lamp housing generation and the miniature deformation of lamp housing material, cause the seal failure of traditional approach.
The technical scheme solved is: a kind of light fixture waterproof construction, the inner space comprising lamp housing is the cavity of sealing, cavity Built-in light luminescent device and accordingly circuit part and lamp assembly, seal chamber there is opening, be provided with at opening part and change the device of volume, it is characterized in that: the opening part of the annular seal space of light fixture is equipped with air bag or barrier film and can free-extension.
Its advantage is: thus reduction is subject to the positive and negative pressure in lamp to the requirement of lamp housing mechanical property and encapsulant and reduces, extend the shell of light fixture and the service time of encapsulant, what lamp interior did not have moisture content in outside air enters light source and circuit part, extends the service life of light fixture.
Accompanying drawing explanation
Fig. 1: for air bag is built-in.Light supply apparatus is positioned in the annular seal space in the lamp housing assembly of sealing; and have opening; the environmental seal of the air inlet/outlet of air bag and this opening; the inside of air bag communicates with hull outside air; when the air heats swelling gasbag in light supply apparatus adstante febre chamber is squeezed contraction; so inside air bag space communicates with lamp housing outside and diminishes, realize pressure balance, protect traditional sealing device not to be damaged.
Fig. 2: be air bag external.Its principle realized is the same with the explanation of figure mono-, and this mode is beneficial to produces and the many protective devices of palpus, is not damaged in the process of producing to protect air bag.
Fig. 3: be diaphragm type, it is the same with the explanation of figure mono-that it realizes principle, this mode can be used for because using when space problem cannot place air bag, also has its barrier film of protective device not to be damaged.
Detailed description of the invention
This light fixture waterproof construction is the opening part at light fixture cavity, place air bag or barrier film, be exactly that air bag or barrier film air inlet/outlet make the space of annular seal space be extended with mode bonding or mechanical compaction around the opening part of light fixture seal chamber or shrink, realize the space size changing light fixture seal chamber, realize eliminating in light fixture annular seal space expanding with heat and contract with cold producing the pressure with lamp housing assembly.Three kinds of structures are specifically had to be respectively accompanying drawing 1, accompanying drawing 2, accompanying drawing 3.
Claims (1)
1. a light fixture waterproof construction, the inner space comprising lamp housing is the cavity of sealing, cavity Built-in light luminescent device and accordingly circuit part and lamp assembly, seal chamber there is opening, be provided with at opening part and change the device of volume, it is characterized in that: the opening part of the annular seal space of light fixture is equipped with air bag or barrier film and can free-extension.
