Abstract

The utility model discloses an ultra-thin LED flexible lamp bar. The ultra-thin LED flexible lamp bar comprises a core wire guide bar, a punching open groove formed in the axial direction of the core wire guide bar, a flexible circuit board arranged in the punching open groove, and LED beads arranged on the flexible circuit board, wherein the LED beads are arranged at the side, close to the punching open groove, of the circuit board, and the punching open groove is provided with square holes matched with the LED beads in size. According to the ultra-thin LED flexible lamp bar, the LED beads are arranged in the square holes of the core wire guide bar, the thickness of a product is largely reduced, the ultra-thin flexible lamp bar is achieved, and the application range is further widened.

Description

A kind of ultra-thin LED flexible lamp strip

Technical field

The utility model relates to a kind of LED surface-mounted lamp band, relates in particular to a kind of ultra-thin, LED flexible lamp strip that overlength is serial that had not only been applicable to high pressure (civil power) but also had been applicable to low pressure (12-36VDC).

Background technology

Conventionally all use LED SMD lamp pearl to make the high pressure of all size, low pressure surface-mounted light bar or lamp band, for improving the security of LED surface-mounted light bar or lamp band, the protective jacket that generally will put layer of transparent polyvinylchloride to lamp bar or lamp band, for preventing extraneous damage and waterproof and dustproof etc.Existing transparent PVC protective jacket is the material made from oiliness auxiliary agent.In the use procedure of lamp band, heating can cause PVC oily matter to decompose out fully by LED SMD lamp pearl, being absorbed, cause LED SMD lamp integument fluidisation end-of-life.

Existing high pressure (110-240VDC), low pressure (12-36VDC) surface-mounted light bar, lamp band, it comprises transparent PVC sleeve pipe, in PVC sleeve pipe, be provided with a PVC heart yearn sliver, one side of sliver is provided with circuit board, mounted LED lamp bulb again on circuit board, this in layer structure of stack, component height in PVC sleeve pipe is also superposeed, therefore, the surface-mounted light bar of making, lamp band are conventionally all very thick, impact heat radiation, not only wasted the material of PVC sleeve pipe, and very thick surface-mounted light bar, its application of lamp band also can be subject to corresponding restriction.

Utility model content

Of the present utility model in order to solve above-mentioned problems of the prior art, a kind of ultra-thin LED flexible lamp strip transparent, that be difficult for stretcher strain that not only can not decompose oil nature under the condition of high temperature is proposed.

The ultra-thin LED flexible lamp strip the utility model proposes, it comprises a heart yearn sliver, along the open slot of a punching of sliver axial direction setting, be located at the flexible circuit board of punching in open slot and be located at the LED lamp pearl on flexible PCB, described LED lamp pearl is located at a side of close punching open slot on circuit board, described punching open slot is provided with the square opening matching with LED lamp pearl size, profiled holes.Adopt transparent not oiliness material to make protective jacket, greatly improved ultra-thin LED paster flexible light band, the service life of lamp bar.

Preferably, the outer also cover of described heart yearn sliver has the not oiliness material of layer of transparent to do protection tube, and heart yearn sliver adopts the composite material of TPUE rubber TPU or silica gel or polyvinylchloride or TPUE rubber TPU and polyvinylchloride to make; Described sleeve pipe adopts the composite material of TPU or silica gel or TPU+PVC to make.

Described transparent grade other not oiliness material do protection tube, can be rectangular tube, also can D shape body etc. various deformation body.

The utility model has changed the structure of LED flexible lamp strip, and the thickness of lamp bar is reduced greatly, can be applied in more field, has widened the scope of application of flexible lamp strip.The utility model adopts resistant to elevated temperatures (TPU, silica gel, PVC+TPU combination ingredient, PVC) to make heart yearn sliver, and in heart yearn sliver wall body, the wire that tensile strength is higher is set.This heart yearn wire can guarantee the lamp bar energising distortion of both can having reeled, can there is not larger stretcher strain again, can also be directly connected in the civil power of high voltage, adopt copper conductor to have can to have overcome by larger electric current low-pressure lamp band and can only do the restriction of 5 meters, and be unlikely to go wrong.The more important thing is the thickness of the product reducing by punching open slot, the amount of heat that can fast LED be produced distributes, thereby guaranteed that LED light source can normally be used under high voltage, so that extended the service life of lamp bar, effectively overcome the defect of existing lamp bar.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described further, wherein:

Fig. 1 is the schematic perspective view of the utility model preferred embodiment.

The specific embodiment

As shown in Figure 1, a kind of ultra-thin LED flexible lamp strip the utility model proposes, comprise that one by TPU, or silica gel, or the sleeve pipe 1 that oiliness material is not made such as TPU+PVC composite material, in sleeve pipe, be provided with a white by TPU, or silica gel, or TPU+PVC composite material, or the heart yearn sliver 5 made of PVC, on this heart yearn sliver 5, along its axis direction, be provided with a punching open slot, in punching open slot, placing a bar shaped flexible PCB 3, the side that flexible PCB pastes punching open slot is provided with LED lamp pearl 4, on heart yearn sliver, in place corresponding to lamp pearl, have the corresponding square opening of size, expose the lamp pearl on flexible PCB, in heart yearn sliver 5 wall bodies of punching open slot both sides, be also provided with the wire 2 of connecting circuit board 3.In the present embodiment, sleeve pipe has adopted the body of rectangle, and those skilled in the art as required sleeve pipe are set to D shape body or other distortion body.

The utility model has changed the structure of each parts stack of original lamp bar, LED lamp pearl outstanding on flexible PCB is arranged in each square opening of heart yearn sliver 5, the integral thickness of lamp bar is reduced greatly, lamp bar thickness after improving is only 1/2nd original left and right, can greatly save making material and the cost of sleeve pipe.In addition, what the utility model adopted is that the materials such as resistant to elevated temperatures TPU, silica gel, TPU+PVC composite material, PVC are made heart yearn sliver 5, and adopted the not material of oiliness material to make sleeve pipe 1, for example TPU, silica gel, TPU+PVC composite material, a large amount of heat that LED is produced can distribute rapidly by heart yearn sliver and sleeve pipe, thereby guaranteed that LED light source can normally be used under higher voltage, has extended the service life of lamp bar.The wire 2 that the utility model adopts adopts while making low-pressure lamp band be thicker copper conductor greatly improve ability by electric current can make ratio that low pressure length does in the past longer (can only do in the past 5 meters, and can do more than 25 meters now) easily install and use.The wire 2 that the utility model adopts is also that tensile strength is higher, because lamp bar is in use and transportation, often need to reel or deformation, this wire can bear larger stretching, can not produce distortion, the civil power that connects high pressure is also not easy to be burned, so short-circuit risks is very little, has further promoted the service life of lamp bar.

Above specific embodiment is only in order to illustrate structure of the present utility model, and those of ordinary skill in the art can make various deformation and variation under design of the present utility model, and these distortion and variation include within protection domain of the present utility model.
