Description
Technical field
The present invention relates to field of illuminating lamps, particularly a kind of LED lighting.
Background technology
For the light fixture of classroom, Office Area or indoor public domain, mostly be at present the fluorescent lamp fluorescent lamp of Grille lamp or belt supporting frame, generally adopt T8 or T5 fluorescent lamp fluorescent tube or LED fluorescent tube as light source.Though the price of T8 or T5 fluorescent lamp fluorescent tube is low, but it contains poisonous mercury, no matter be use procedure or offal treatment, to environment, all can produce pollution, and it in use also can produce a large amount of ultraviolet rays and strobe light, this can cause great injury to human body skin and eyesight.LED fluorescent tube does not have the harmful substances such as mercury and in use can not produce ultraviolet ray and strobe light, and its light efficiency is the twice of fluorescent lamp fluorescent tube, life-span is two to three times of fluorescent lamp fluorescent tube, in the situation that there is no more good method, is proper fluorescent lamp fluorescent tube substitute.
The heat-resisting very poor of LED is on record, will inevitably bring the problem in wick life-span.The Design Thinking that existing LED light fixture is continued to use fluorescent lamp often designs, and light fixture is general causes that LED junction temperature is too high and light decay is serious because area of dissipation is limited or heat-conducting effect is poor.Such as, the LEDT8 fluorescent tube of half PC material half aluminum alloy materials, whole cooling surface area only has half surface area of fluorescent tube, because of its heat-delivery surface limited, easily cause LED chip because excess Temperature light decay is serious for a long time, thereby greatly shortened the life-span of fluorescent tube, made long-life feature of LED originally can not get fully demonstrating.The price of adding LED lamp fluorescent tube is several times of fluorescent lamp fluorescent tubes, certainly will increase engineering alternative costs, makes applying of LED fluorescent tube increase resistance.
Summary of the invention
The technical problem that the present invention solves: the heat radiation of solution LED light fixture is bad, and LED chip light decay is serious, and light fixture short defect in service life, provides a kind of good heat dissipation effect, and stability is high, the LED indoor illumination light fitting of long service life.
For achieving the above object, the concrete technical scheme that the present invention adopts is: a kind of high stability LED indoor illumination light fitting, comprising: light source module, light-passing board, aluminum alloy frame, aluminum alloy back plate, fastener for installing, driving power; Described aluminum alloy frame is fixedly connected with aluminum alloy back plate, then forms lamp casing with light-passing board clamping; Described light source module is fixedly placed in housing, and light fixture is installed fixing by fastener for installing; Described light source module comprises circuit board, a plurality of LED lamp pearls of series connection welding on circuit board; By being connected with driving power after a plurality of light source module parallel connections, and with aluminum alloy back plate equal intervals, be arranged in parallel and be fixedly connected with.Like this, it is whole that aluminum alloy back plate and aluminum alloy frame have formed a heat radiation, both served as LED lamp outer casing, the radiator that has served as again LED light fixture, the heat that can in time light source module be produced is transmitted to aluminum alloy back plate, then by aluminum alloy back plate and aluminum alloy frame, heat loss is gone out, effectively reduce the temperature of light fixture integral body, reduce to greatest extent the light decay of LED chip, improved the stability of light fixture, extended light fixture service life.
Preferably, 24-36 LED lamp pearl of series connection welding on described circuit board.
Preferably, described light source module quantity is 18-72.
Preferably, described light source module and aluminum alloy back plate are screw or gluing fixing.
Preferably, described aluminum alloy frame width is 40-60mm.
Preferably, described aluminum alloy back plate outer surface anodized.
Preferably, the wide 298-598mm*298-1198mm that is of a size of of the long * of described aluminum alloy back plate, more preferably 298mm*298mm, 298mm*598mm, 598mm*598mm or tetra-kinds of specifications of 598mm*1198mm; Described aluminum alloy back plate is established reinforcement.
Preferably, described light-passing board is acrylic board or poly (methyl methacrylate) plate.
Preferably, described fastener for installing comprises inhales top fastener for installing (7), side direction fastener for installing (8) or lifting fastener (9), inlays, lifts, inhales the multiple mounting modes such as top to adapt to.
Compared with prior art, because heat conduction efficiency improves, area of dissipation is larger, and LED chip junction temperature can be controlled in 60 ℃, can give full play to long feature of LED life-span.Owing to having adopted the series connection of a plurality of lamp pearls, the mode of a plurality of light source module parallel connections, makes lamp pearl run into risk over rated current and drops to minimumly, has improved the stability of light source.Except embedded installation, can also lift and inhale top and install, expanded the range of application of light fixture.
