Description

LED lamp with water-proof function

Technical field

The present invention relates to a kind of light fixture, relate in particular to a kind of LED lamp with water-proof function.

Background technology

Compare with conventional light source, LED be the high and low radiation of a kind of luminous efficiency, low power consumption, long-life, low driving voltage, startup fast, the illuminator of environmental protection.Rapid with LED as the fluorescent lamp technical development of light source.Disclose a kind of LED fluorescent lamp like Chinese patent 101839413A, comprised cooling base, be fixed in lampshade and light source substrate on the cooling base; Drive circuit; Be installed in the power connector of cooling base and lampshade end, a plurality of light emitting diodes are installed on the said light source substrate, drive circuit is arranged at cooling base inside; Light source substrate comprises at least two sub-light source substrates; The angle of the extended line of led lighting direction is less than 180 degree on said two sub-light source substrates, and the led lighting direction is different on the sub-light source substrate, can increase the luminous intensity distribution zone and the light angle of LED fluorescent lamp.

And for example Chinese patent 101576208 discloses a kind of LED fluorescent lamp; The substrate that comprises body, heat conductive pad, felt pad, lampshade, a plurality of LED and fixing said LED; The one side of said body has radiator, and its relative one side has first groove, and said body first groove two relative last groove edge have bulge respectively; The edge of opening of said lampshade has respectively the holding section that fastens with said two edge bulges; Said felt pad places in first groove of said body, and said felt pad has second groove, and said heat conductive pad and substrate are fixed in second groove of said felt pad successively.Through below said substrate, establishing heat conductive pad and felt pad successively, can the heat that LED sends be transmitted on the body rapidly, improved its radiating effect.Above-mentioned patent has been done improvement from illumination and heat radiation aspect, if but problems will appear in long-term the use out of doors like this in the environment of inclement condition.

Summary of the invention

The present invention solves the existing in prior technology deficiency, uses out of doors or waterproof requirement is arranged thereby design a kind of suiting, and good seal performance, radiating effect ideal have the LED lamp of water-proof function.

Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of LED lamp with water-proof function; It is characterized in that: comprise the tubulose lampshade, lampshade is complete transparent optical pipe, can play the effect of waterproof and printing opacity; Said lampshade two ends connect the light tube jacket with sealing effectiveness; In the said lampshade LED is arranged, the substrate of fixing said LED, substrate is aluminium or aluminium alloy manufacturing; Have at least a face can with the hollow and thin-walled section bar radiator of baseplate-laminating, radiator is aluminium or aluminium alloy.

Technical scheme of the present invention can also be further perfect:

As preferably, said light tube jacket comprises body, is installed in the pad in the body, with the soft waterproof plug that pad closely contact, is connected in the end cap of body end face, and said end cap inboard and soft waterproof jam-pack connect airtight and touch.

As preferably, said body is socketed in the lampshade outside, and said pad matches with the lampshade internal diameter; Said pad, soft waterproof plug, end cap are provided with and can hold the through hole that radiator passes through.

As preferably, said LED is arranged at the two sides of radiator symmetrically.

As preferably, said LED be arranged at symmetrically radiator around, to form light beam.

As preferably, connect through sealing screw between said pad, soft waterproof plug, the end cap.

As preferably, said hollow radiator is provided with shaft orientation reinforcing rib.

As preferably, said lampshade inner face is provided with shaft orientation reinforcing rib.

As preferably, said light tube jacket is provided with the jockey that is connected with fixed body.

As preferably, has flowing liquid in the middle of the said radiator, to improve heat dispersion.

The invention has the beneficial effects as follows:

1, the outside is a complete transparent optical pipe, can play the effect of waterproof and printing opacity.

2, radiator is a hollow metal pipe that passes whole fluorescent tube, and the one side at least of metal tube is put down, and ability and led circuit plate fit tightly, and the heat that LED is produced is in time led at the aluminum pipe (hollow metal pipe) of heat radiation and left.

3, the two ends of fluorescent tube are sealed, and have waterproof action; But two end faces of the heat radiation aluminum pipe (hollow metal pipe) of hollow are penetrating, and core is open, can lean on air or liquid flow to take away heat.

4, the sealing at lampshade two ends is adopted like the sealing of soft waterproof plugs such as silica gel, thereby reaches waterproof action.
