2, CN202432299U, title " a kind of LED line source with water-proof function ", comprise an installation aluminum frame, to be connected to the PC pipe installing aluminum frame, the pcb board be arranged in PC pipe, to be arranged at the multiple LED on pcb board and to be arranged at the plug installing aluminum frame two ends, described pcb board embedding has epoxide-resin glue, the contact portion of described installation aluminum frame, PC pipe and pcb board and plug is provided with silica gel, and also there is dozen silica gel sealing in the edge of whole LED line source.
The weak point that above-mentioned background technology exists: one is because epoxy resin and silica gel during immersion use, there will be infiltration and cause light fixture to lose efficacy and damage, can not reach the object of long-term waterproof for a long time in high humidity or water; Two is that epoxy resin and silica gel also there will be xanthochromia when using out of doors, cracking or with the situation such as shell disengagement, cause aqueous vapor to enter light source internal, cause light source fails.
3, CN102628562A, title " LED lamp bar and preparation method with full waterproof potting structure ", LED lamp bar main body (1); The full waterproof potting structure (2) in LED lamp bar main body (1) is wrapped in extrusion molding ring.The utility model additionally provides the glue sealing method of LED lamp bar, comprising: provide LED lamp bar main body (1); And by extrusion process, adhesive material extrusion molding is molded in LED lamp bar main body (1), and forms the full waterproof potting structure (2) of ring bag LED lamp bar main body (1).The waterproof encapsulating material of encapsulating is carried out for extrusion process to LED lamp bar, preferably can adopt PVC material, TPU material or PVC and TPU compound.This kind of encapsulating material not only can perform well in extrusion moulding, adapt to the profile of LED lamp bar well, but also there is good thermal diffusivity, light transmission and weatherability, be particularly suitable for wrapping up LED lamp bar, and can ensure the good light transmittance of LED lamp bar, the waterproof potting structure that therefore this type of waterproof encapsulating material makes does not affect normal work, the luminescence of LED and dispels the heat.Its weak point: the performance that those skilled in the art expect according to PVC, thinks that PVC material can only as airtight and watertight padding, can not independently as light emitting source housing.
Utility model content
Purpose of design: avoid the weak point in background technology, design a kind of weather resistance both with good anti-ultraviolet function and excellence, again can independently as LED light source lamp housing, simultaneously again can for a long time out of doors, underwater operation and the printing opacity LED water proof lamp group that steam infiltrates can not occur.
Design: in order to realize above-mentioned purpose of design.The utility model adopts PVC paste material as the design of each LED capsul of LED group, is technical characteristics of the present utility model.The object done like this is: it changes those skilled in the art for a long time and thinks that PVC paste material is due to good dispersion property, soft material field and sealing inserts can only be used for, as artificial leather, vinyl toy, soft trade mark, wallpaper, paint, foamed plastic etc., and the technology prejudice that can not make as illuminating source housing, and the application around it, adopt PVC paste material as LED light emitting source carrier, not only process equipment is inexpensive, mould simple cheap, can be made into F-SP LED and by LED lamp group in series, and foaming easily, the goods number of times that is heated is few, translucent effect is good, heat-resisting, shock resistance, tear-proof, and can be a small amount of, multi items is produced, achieve open air simultaneously, hermetically sealed under water, round-the-clock weather-proof use.
The application adds for absorbing ultraviolet absorbent in PVC paste; because ultra-violet absorber can absorb sunlight or fluorescence source middle-ultraviolet lamp part; and this body structure does not change; it can convert high-octane ultraviolet luminous energy to heat energy or nondestructive longer light wave discharges; thus the material that protection is added with ultra-violet absorber exempts from ultraviolet damage; in PVC paste, add ultra-violet absorber can effectively stop the ultraviolet in sunlight to the destruction of LED lamp outer shell, extends the service life of light fixture.
The object that the application adds antioxidant in PVC paste is: because the PVC paste plastics after plasticizing are easily aging under the factor effects such as light, heat, oxygen, solvent, auxiliary agent, HCl, and namely degraded or crosslinked, makes its physical and mechanical properties degenerate, reduction of service life.Add antioxidant in the application's PVC paste effectively suppress or reduce the macromolecular thermal oxide of plastics, photooxidation reaction speed, improve heat-resisting, the light fastness of the PVC paste plastics after plasticizing significantly, delay the degraded of the PVC paste plastics after plastifying, ageing process, improve the weather resisteant of PVC paste made LED waterproof lamp housing, extend the PVC paste plastic products service life after plasticizing.
The object that the application adds low temperature plasticizer in PVC paste is: because low temperature plasticizer and PVC paste material have good compatibility, plasticization effect is good, not easily emanate, not easily ooze out, and low temperature plasticizer can reduce the vitrification point of the PVC paste plastics after plasticizing, make its pliability good, the cold tolerance of the PVC paste plastics after plasticizing can be improved, make it still have good serviceability at cold district.
The object that the application adds stabilizing agent in PVC paste is: PVC paste material at high temperature plastifies or uses under high temperature, very easily releases HCL, forms unstable polyene structure.Meanwhile, HCL has autocatalysis, and PVC can be made to degrade further.In addition, if aerobic exists or has iron, aluminium, zinc, tin, copper and cadmium plasma to exist, all to degrade catalytic action to PVC, accelerate that it is aging.Therefore will there is various bad phenomenon in plastics, as variable color, distortion, be full of cracks, mechanical strength decline, edge hydraulic performance decline, embrittlement etc.In order to address these problems, in PVC paste plastics, different cultivars must be added, the stabilizing agent of different number.
Technical scheme: a kind of printing opacity LED water proof lamp group, multiple LED conspires to create LED group, and the light emitting source of described one or more LED is arranged by one or plurality of LEDs and forms, and one or more LED is overmolding to printing opacity water proof lamp group by the sealing of PVC paste material.
