Further, in the described groove that is in the light, be provided with reinforcement feature, described reinforcement feature is arranged at one side backlight and the placement parallel with flexible PCB of flexible PCB, described reinforcement feature is that rigidity is not bent in the direction that is parallel to flexible banded light source luminescent face, this reinforcement feature can only be realized bending along the direction perpendicular to the banded light source luminescent face of flexibility, limit the side direction activity point of view of lamp body, avoided in use excessive sideways bending of lamp body to cause welding position sealing-off, the fracture of parallel interface, LED and circuit board.
Further, gluing being close between described reinforcement feature and flexible PCB, be convenient to assembling.
Further, described reinforcement feature is metallic plate, and it has taken into account the effect of reinforcing and heat conduction.
Further, the top of described insulating coating is also provided with diffusion layer, and described diffusion layer is mixed with particle light to reflection or diffusion or refraction action, and the spot light that LED can be sent becomes area source, makes lamp body luminous softer, even.
Further, rounded, the square or arch of the cross section of described diffusion layer, further improves the effect of scattering and refraction.
Further, the tectal inside of described soft light is also provided with copper stranded conductor, and described light source is realized and being electrically connected to copper stranded conductor.Because copper stranded conductor can bear larger electric current, when lamp body is done longlyer, can not damage because electric current is excessive lamp body.
Further, described flexible PCB comprises many flat metal wires and is pressed on the insulating barrier of flat metal conductive line surfaces, described part flat metal wire disconnects district according to required being provided with of circuit, and LED is welded in and disconnects district or be connected across on adjacent two flat conductors.This kind of non-aggressive circuit board has good thermal diffusivity, resistance to bending and flexibility, and can adopt SMT full automation production technology, is conducive to reduce costs.
Further, described flat metal wire comprises one group of power line and at least one series line, described insulating barrier comprises the first insulating barrier that is pressed on flat conductor upper surface and the second insulating barrier that is pressed on flat conductor lower surface, described the first insulating barrier and the second insulating barrier are folding along its length, and described power line and series line lay respectively at different fold planes.Like this, circuit board can fold along its length, and width can be done narrowlyer, and lamp body inner space is compacter.
Further, the first insulating barrier of described flexible circuit board and the second insulating barrier are all provided with die-cut mouthful along its length, the position of die-cut mouthful of described the first insulating barrier and the second insulating barrier is corresponding, the first insulating barrier, the second insulating barrier are all die-cut mouthful folding along self, the folding of flexible circuit board of being so just more convenient for, and can perk after folding.
The beneficial effects of the utility model are: the reinforcement feature of the utility model setting guarantees that lamp body can only be along the direction realization bending perpendicular to the banded light source luminescent face of flexibility on the one hand, limited the side direction activity point of view of lamp body, avoid in use excessive sideways bending of lamp body to cause welding position sealing-off, the fracture of parallel interface, LED and circuit board, can effectively conduct on the other hand the heat producing of the inner LED of LED neon light, thus the problems such as the dead lamp pearl producing due to excess Temperature while avoiding LED work or light decay acceleration; Described bag is carried out layer and is formed by encapsulating mode by PU glue or TPU glue, and good seal performance, can play good waterproof and insulation effect.
