The LED light sources are attached on the flexible circuit board, the silica gel sleeve is sleeved on the flexible circuit board, the openings of both ends of the silica gel sleeve are plugged by the silica gel sleeve plugs, and the LED light bar also comprises an epoxy resin glue layer, which is arranged between the LED light sources and the silica gel sleeve. Since the silica gel sleeve is combined with the filled epoxy resin glue layer and both ends of the silica gel sleeve are plugged by the silica gel sleeve plugs, the elements in the LED light bar are under dual protection, and the LED light bar has good water-proofing and dust-proofing effects.
Description
Technical field
The utility model relates to field of light fittings, particularly relates to a kind of LED lamp bar.
Background technology
LED lamp bar is widely used in the industries such as furniture, automobile, advertisement, illumination, steamer and house decoration.LED lamp bar divides again two kinds of flexible LED strip and the hard lamp bars of LED, flexible LED strip is to adopt flexible PCB to do the assembling wiring board, assembles with paster LED, and the thickness of its product only is the thickness of one piece of coin, take up space less, and can arbitrarily cut off, joint and luminous unaffected.The flexible PCB material is soft, and is can be arbitrarily crooked, folding, reel, can be arbitrarily mobile and stretch and can not fracture at three dimensions.Be suitable for irregular and the narrow space use, also because of its arbitrarily bending and coiling, be suitable for the various patterns of any combination in ad decoration.
For the application of LED lamp bar in outdoor environment, traditional flexible LED strip contains a large amount of ultraviolet rays in the outdoor irradiation that suffers for a long time natural daylight in the natural daylight, LED lamp bar suffers the easy aging yellowing of ultraviolet radiation, cause transparency to descend, affect lighting quality.
In addition because outdoor bad border is more abominable, traditional flexible LED strip is long-term use after often because entering dust or moisture causes short circuit, the damage led chip.
The utility model content
Based on this, be necessary to be difficult to the preventing dust water problem for traditional flexible LED strip, a kind of LED lamp bar of dustproof and waterproof is provided.
A kind of LED lamp bar, the silica gel sheath and the silica gel sheath plug of being made by silica gel of the both ends open that comprises FPC, a plurality of led light source, made by silica gel, described a plurality of led light source is mounted on described FPC, described silica gel sheath is sheathed on described FPC, described silica gel sheath plug is plugged in the both ends open place of described silica gel sheath, also comprise the epoxy glue layer of being made by epoxide-resin glue, described epoxy glue layer is arranged between described led light source and the described silica gel sheath.
Among embodiment, described flexible PCB is the circuit board that is become by two-sided calendering copper therein.
Among embodiment, described a plurality of led light sources are a plurality of led chips therein, and described a plurality of led light sources are connected in parallel, and wherein, each led chip is connected in series a current-limiting resistance.
Among embodiment, also comprise the control circuit that is electrically connected with described FPC therein.
Above-mentioned LED lamp bar, LED lamp bar is combined with the epoxy glue layer of embedding by silica gel sheath, and the shutoff of silica gel plug is adopted at the two ends of silica gel sheath, and components and parts duplicate protection in the lamp bar has good waterproof and dust-proof effect.
Description of drawings
Fig. 1 is the schematic diagram of the LED lamp bar of an embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1, in one embodiment, a kind of LED lamp bar, the silica gel sheath 130 and the silica gel sheath plug 140 of being made by silica gel of the both ends open of comprise FPC 110, a plurality of led light source 120, being made by the silica gel that is doped with ultra-violet absorber.Usually, flexible PCB 110 is the circuit board that is become by two-sided calendering copper.A plurality of led light sources 120 are mounted on FPC 110, a plurality of led chips of a plurality of led light sources 120 for being connected in parallel, and wherein, each led chip is connected in series a current-limiting resistance 150.Usually, LED lamp bar also comprises the control circuit 160 that is electrically connected with FPC 110, and this control circuit 160 is used for connecting controller.Led chip adopts ruddiness, green glow, blue light three chips light sources, compound by light, and the adjusting control with controller reaches various different colors.Silica gel sheath 130 is sheathed on FPC 110.Silica gel sheath plug 140 is plugged in the both ends open place of silica gel sheath 130.The plug that silica gel sheath plug 140 is made for the silica gel that is doped with ultra-violet absorber.Silica gel sheath 130 and silica gel sheath plug 140 add ultra-violet absorber in silica gel when moulding is produced, this ultra-violet absorber can be divided into salicylate class, benzophenone class, benzotriazole, group-substituted acrylonitrile, triazines and hindered amines by chemical constitution.When ultraviolet ray is shone, can absorb most of ultraviolet light, reach the purpose of anti-aging jaundice, make the transparency of LED lamp bar be in all the time preferably state, keep preferably lighting quality.
In the present embodiment, LED lamp bar also comprises by the epoxide-resin glue that is doped with nano particle and makes epoxy glue layer 170.Epoxy glue layer 170 is arranged between led light source 120 and the silica gel sheath 130.Epoxy glue layer 170 is formed between silica gel sheath 130 and led light source 120 by the epoxide-resin glue embedding that is doped with nano particle.Wherein, nano particle is silica dioxide granule.The epoxide-resin glue of embedding adds nano particle silica in the LED lamp bar, make the light transmittance of LED lamp bar better, simultaneously, nano particle has preferably infrared emissing ability, with led light source 120 send infrared through repeatedly the emission after radiate from silica gel sheath 130 uniformly, avoided the local ageing of the silica gel sheath 130 that infrared local accumulation causes, prolonged the service life of LED lamp bar, be applicable to various than rugged environment.LED lamp bar is by the combination of silica gel sheath 130 with the epoxide-resin glue embedding, and components and parts duplicate protection in the lamp bar has good waterproof and dust-proof effect.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
