Description

Light fixture

Technical field

The present invention relates to a kind of light fixture, relate in particular to and a kind ofly dismantle easy to maintenance and have the light fixture of water-proof function.

Background technology

Because light emitting diode has long, advantage such as luminous efficiency is high, volume is little, pollution is low of life-span, be taken as perfect light source more in recent years manyly and be widely used in the various light fixtures, like indoor lamp, outdoor lamp.

Outdoor lamp is owing to be in the open air; It receives the influence of various natural causes easily; Like the water droplet on rainy day, in case these water droplet inlet chamber outer lamps are inner, not only have influence on outdoor lamp appearance looks elegant, shelter from the light that light source sends and make people can't differentiate the road surface situation and lead to a disaster; And, will the major injury light source.Therefore, marine glue is irritated or prevent that along seam crossing coating marine glue water droplet from getting into lamp interior for waterproof is generally filled whole light fixture, and still, this kind way is labor intensive, time not only, and the dismounting maintenance is also inconvenient.

Summary of the invention

In view of this, being necessary to provide a kind of dismantles easy to maintenance and has the light fixture of water-proof function.

A kind of light fixture; It comprises circuit board, lamp housing and lampshade; Said circuit board is housed in the containing cavity that said lamp housing and lampshade limit, and said lamp housing comprises base plate and the first side wall that is positioned at the relative both sides of said base plate, and said the first side wall outer surface has first holding section; Said first holding section comprises first extension that is arranged on the said the first side wall, by first kink, second extension and second kink of said first extension to said base plate bending; The extension of said second extension and said second kink connects, and said second extending part is between the said base plate and first extension, and said second kink is bent to form to said the first side wall by said first kink; Said lampshade comprises lid and second sidewall that is positioned at the relative both sides of said lid; Said second sidewall has second holding section, and said second holding section is formed to inner extension of said containing cavity by the end of said second sidewall, matches so that said lampshade is installed on the said lamp housing in said first holding section and second holding section; Between the said base plate and second extension the 3rd extension is set; Be formed with a receiving space between said first holding section and second holding section, said receiving space contains first water resistance gasket, and said second holding section is connected to said the 3rd extension and said first water resistance gasket.

The light fixture of present embodiment is provided with first water resistance gasket between lamp housing and lampshade; Rather than waterproof material poured in the lamp housing; And lamp housing and lampshade adopt the mode of engaging to cooperate, therefore; Need not destroy light fixture can overhaul the circuit board dismounting, keep in repair or change, so light fixture is dismantled easy to maintenance and had water-proof function.

Fig. 2 is the decomposing schematic representation of embodiment of the invention light fixture.

Fig. 3 is an III-III place enlarged drawing among Fig. 2.

The specific embodiment

To combine accompanying drawing below, the present invention will be done further detailed description.

Please consult Fig. 1, Fig. 2 and Fig. 3 in the lump, the light fixture 10 that the embodiment of the invention provides comprises lamp housing 11, lampshade 12, circuit board 13, first water resistance gasket 14, second water resistance gasket 15 and end plate 16.Wherein, lamp housing 11, lampshade 12, first water resistance gasket 14 and second water resistance gasket 15 can adopt the injection forming method manufacturing.

Lamp housing 11 comprises base plate 111 and two the first side walls 112, the space of a first side wall 112 and a containment circuit board 13 of base plate 111 qualifications.Circuit board 13 is provided with lead 131 and light source 132, and light source 132 can be fluorescent lamp, light emitting diode etc.

The first side wall 112 is provided with chute 112a, and circuit board 13 is installed in the chute 112a versatilely, thereby makes circuit board 13 dismounting from light fixture 10 easily.

The first side wall 112 stretch out form first extension 113, second extension 114 and the 3rd extension 115, the three extensions 115 be parallel to each other near base plate 111, second extension 114 between first extension 113 and the 3rd extension 115 and width less than the width of first extension 113.

The end of first extension 113 is bent to form the first kink 113a to base plate 111 directions, and the length of the first kink 113a equals distance between first extension 113 and second extension 114.The first kink 113a extends to form the second kink 113b to the first side wall 112; The prolongation of itself and second extension 114 connects, and the first side wall 112, first extension 113, second extension 114, the first kink 113a and the second kink 113b are common to limit a receiving space 116 thereby make.

One end of " worker " font first water resistance gasket 14 is contained in the receiving space 116 and is close to the first side wall 112, first extension 113, second extension 114, the first kink 113a and the second kink 113b.First water resistance gasket 14 not only can closely be contained in the receiving space 116 and can in receiving space 116, be drawn out of.When first water resistance gasket 14 wears out, when damaging, can its extraction be changed.

The material of first water resistance gasket 14 be EPDM (EPDM), silica gel (silicone), vinyl chloride (PVC) or fiber-reinforced plastic (Fiber Rainforced Plastics, FRP) etc.

Certainly, first water resistance gasket 14 also can be " T " font.

Lampshade 12 comprises that lid 121 and " L " shape second sidewall 122, the second sidewalls 122 that are positioned at lid 121 relative both sides comprise roughly the vertical wall 122a vertical with lid 121 and the horizontal wall 122b of almost parallel lid 121.Distance between two vertical wall 122a is greater than the distance between two horizontal wall 122b; Vertically the height of wall 122a is more than or equal to the distance between first extension 113 and the 3rd extension 115; Thereby make horizontal wall 122b matched with lamp housing 11 and to combine closely with first water resistance gasket 14 with the zone between second extension 114 by the 3rd extension 115, promptly lampshade 12 is fastened on the lamp housing 11.Because lamp housing 11, lampshade 12 are all combined closely with first water resistance gasket 14, not only make the sealing of light fixture 10 better, and make that water droplet lamp housing more difficult to get access 11 is interior and make light fixture 11 have the water resistance of getting well.

Lamp housing 11 places chute 112a with circuit board 13 after assembling completion with lampshade 12, then two ends is sealed to strengthen the water-proof function of light fixture 10 with second water resistance gasket 15, with screw end plate 16 is fixed on the lamp housing 11 again.End plate 16 is provided with cable holder 17, and the lead 131 on the circuit board 13 links to each other with external power source via cable holder 17.

The material of second water resistance gasket 15 is EPDM, silicone, PVC or FRP etc.

When circuit board 13 goes wrong, because first water resistance gasket 14, second water resistance gasket 15 adopt mechanical systems to be arranged in the light fixture 10, need not destroy light fixture 10 and can circuit board 13 dismountings overhauled, keep in repair or changed, therefore, convenient disassembly; Because the existence of first water resistance gasket 14 and second water resistance gasket 15 makes light fixture 10 have water-proof function.

In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, these are according to the variation that the present invention's spirit is done, all should be included in the present invention's scope required for protection in.
