Description
Technical field
The utility model relates to decoration or lighting field, particularly relates to a kind of LED flexible bar type lamp with diffusion sheet.
Background technology
LED flexible bar type lamp can be used for contour of object display or decoration, its structure is generally: at the coated one deck insulation sheath in the periphery of flexible strip shape LED lamp panel, described strip-shaped LED lamp plate is turned up the soil each other for a plural number adopting surface mounted LED and is welded on FPC, insulation sheath is mainly divided into the transparent body and mist lean type, wherein the insulation sheath of mist lean type can carry out mixed light to the light of LED, and the light that LED flexible bar type lamp is sent is more evenly soft.But the general comparatively book of the insulation sheath of LED flexible bar type lamp, if LED spacing is excessive, then still there will be larger hot spot between every two LEDs, the light that LED flexible bar type lamp is sent is even not, even if increase the mist whiteness (namely increasing the concentration of astigmatism powder in insulation sheath) of insulation sheath, its effect improved is also not obvious, and can reduce the injection rate of LED light line, makes the brightness of LED flexible bar type lamp dimmed.
The production technology of LED flexible bar type lamp is generally: insert in extruder by flexible strip shape LED lamp panel, extruder is by micelle heat fused and be coated on LED lamp panel periphery in the mode extruded, because the packaging plastic of adopting surface mounted LED light-emitting area is flexible glue, the luminous heart yearn of LED and electrode gold thread are all fixed in flexible glue, easily scald the electrode gold thread damaging LED when the micelle of heat fused is coated on LED surface by extruder, cause LED not work.On the other hand, LED lamp panel protrudes from flexible circuitry for a plural number adopting surface mounted LED, makes LED lamp panel uneven, is not easy to extruder extruding insulation sheath.
Thus be necessary to do further Improvement and perfection to above-mentioned LED flexible bar type lamp.
Utility model content
The purpose of this utility model is to provide a kind of LED flexible bar type lamp with diffusion sheet, can improving light mixing effect, can protect LED when extruding insulation sheath, being easy to extruder extruding insulation sheath.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of LED flexible bar type lamp with diffusion sheet, comprise the flexible insulation crust with interior bone, be arranged at the flexible LED lamp plate in insulation sheath through hole, described flexible LED lamp plate is that plural LEDs is turned up the soil each other and is welded on FPC, it is characterized in that: the light-emitting area corresponding to LED in insulation sheath through hole is provided with light diffusion sheet.
Further, described insulation sheath is translucent body or the transparent body.
Preferably, described insulation sheath is mist lean type.
Preferably, the vaporific sheet of described diffusion sheet, can spread the light of LED effectively.
Preferably, described diffusion sheet is hard plastic sheet, according to be adopting surface mounted LED, protection paster LED when extruder can be made to extrude insulation sheath; Adopt hard plastic sheet that LED flexible bar type lamp can be made submissiveer, and can prevent the distortion of LED flexible bar type lamp from excessively damaging FPC.
Preferably, described diffusion sheet be close to LED light-emitting area or and LED light-emitting area between offer and put, it is better to offer the diffusion effect put LED light line.
Preferably, described diffusion sheet be close to insulation sheath through hole inwall or and insulation sheath through hole inwall between offer and put, it is better to offer the diffusion effect put LED light line.
Preferably, described LED is adopting surface mounted LED.
Further, the two side of described insulation sheath through hole is provided with draw-in groove, the dual-side of FPC is stuck in draw-in groove, flexible LED lamp plate can be fixed well, make LED can and insulation sheath through hole face open a segment distance between the face of LED luminescence, adopting surface mounted LED can be prevented to be subject to extruding when insulation sheath bends and variable color or damage LED electrical pole gold thread.
The utility model comprises following beneficial effect: the light-emitting area corresponding to LED due to the utility model in insulation sheath through hole is provided with light diffusion sheet,
1, diffusion sheet can coordinated insulation crust carry out light secondary diffusion, thus can improve light mixing effect, make the luminescence of LED flexible bar type lamp more even;
2, because diffusion sheet is arranged on the light-emitting area of LED, when adopt be adopting surface mounted LED time, diffusion sheet can cover on the flexible glue of adopting surface mounted LED end face, LED can be protected largely from crowded wound or scald when extruding insulation sheath;
3, diffusion sheet covers the light-emitting area of all LED, and the rough face that the one side of LED lamp panel luminescence is made up of each LEDs becomes a plane, is easy to extruder extruding insulation sheath.
4, the concentration of spread powder or the thickness of diffusion sheet in diffusion sheet can be adjusted according to the degree of irregularity of lamp body, if each LED is apart from increasing, hot spot between LED increases, and now can increase the thickness of spread powder concentration in diffusion sheet or diffusion sheet, to increase light diffusion thus to reduce hot spot.
It is pointed out that and implement arbitrary product of the present utility model non-required to reach above institute effective simultaneously.
