A kind of light bar utilizing optical fiber luminescent
Technical field
The invention belongs to decorating building lighting technical field, be specifically related to a kind of light bar utilizing optical fiber luminescent.
Background technology
Comprise numerous species for the lamp of decorating building illumination in prior art, but decoration, illuminating lamp are the lamp that outer shape is fixed mostly, the lamp that this shape is fixed cannot be arranged in narrow gap flexibly, has therefore occurred LED.
Light bar is that LED is welded on above copper cash, then puts pvc pipe or the equipment of employing straight forming, and have circular and flat-shaped two kinds, its appellation is distinguished by the quantity of copper cash and the shape of light bar, and two lines are called two wires, and circle just adds circle above, i.e. round two wires; Flat just adds flat word above, i.e. flat two wires.Adopt FPC and FPC to do carrier afterwards, because its processing technology is easier, quality more easily controls, and the life-span is longer, and color and the higher and processing technology that instead of gradually comparatively early of brightness, gradually become trend.Because is all generally welding LED above light bar, therefore also has and be much LED, but be simplified to light bar because noun is oversize.Owing to there being a large amount of LED monomers in light bar, caloric value is large, and cannot install heat abstractor in pvc pipe, the heat that LED sends cannot be discharged rapidly, easily causes LED to cross cause thermal damage, and the service life of light bar is shortened greatly.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of light bar utilizing optical fiber luminescent, this utilizes the light bar of optical fiber luminescent by reducing the quantity of LED, and increases louvre, solves the problem that LED crosses cause thermal damage.
The present invention is achieved by the following technical programs.
A kind of light bar utilizing optical fiber luminescent provided by the invention, comprises lateral emitting optical fiber, substrate, mounting cup, drive circuit board, light-emitting device, lampshade and convex lens; Described lateral emitting optical fiber is fixedly mounted on substrate, described drive circuit board, light-emitting device, lampshade and convex lens are installed in mounting cup, described mounting cup is enclosed within the end of lateral emitting optical fiber, and the end face of the outside of described convex lens and lateral emitting optical fiber is fitted.
Reflective membrane C is also provided with between described lateral emitting optical fiber and substrate.
The end face of described lateral emitting optical fiber away from convex lens end is provided with reflective membrane B.
The madial wall of described mounting cup is provided with reflective membrane A, and described reflective membrane A is placed in the outside of convex lens.
Described light-emitting device is super bright full-color LED lamp.
Described lateral emitting optical fiber is polymer optical fiber.
The outside of described lateral emitting optical fiber is also provided with transparent shield, and described transparent shield is fixed on substrate.
Described transparent shield is provided with coloured coating.
Described mounting cup and lampshade are respectively arranged with louvre A and louvre B.
Beneficial effect of the present invention is: only need the light bar choosing suitable length to be directly arranged on the position of needs installation by substrate, need on transparent shield, coat corresponding color according to different decorative colors, energising can reach the decorative effect of light bar, each section of light bar only needs a LED, not only caloric value is few for it, and reduction energy consumption, extend light bar service life.

Detailed description of the invention
Further describe technical scheme of the present invention below, but described in claimed scope is not limited to.
A kind of light bar utilizing optical fiber luminescent as shown in Figure 1, comprises lateral emitting optical fiber 1, substrate 2, mounting cup 3, drive circuit board 4, light-emitting device 5, lampshade 6 and convex lens 7; Described lateral emitting optical fiber 1 fixedly mounts on a substrate 2, described drive circuit board 4, light-emitting device 5, lampshade 6 and convex lens 7 are installed in mounting cup 3, described mounting cup 3 is enclosed within the end of lateral emitting optical fiber 1, and the end face of the outside of described convex lens 7 and lateral emitting optical fiber 1 is fitted.
Reflective membrane C11 is also provided with between described lateral emitting optical fiber 1 and substrate 2.The end face of described lateral emitting optical fiber 1 away from convex lens 7 end is provided with reflective membrane B10.The madial wall of described mounting cup 3 is provided with reflective membrane A8, and described reflective membrane A8 is placed in the outside of convex lens 7.Utilize reflective membrane to ensure that light does not leak outside, improve the utilization rate of light.
Described light-emitting device 5 is super bright full-color LED lamp.
Described lateral emitting optical fiber 1 is polymer optical fiber, and polymer optical fiber is lateral emitting optical fiber, namely light in the process of transmission constantly from the side-scattered of optical fiber out.
The outside of described lateral emitting optical fiber 1 is also provided with transparent shield 9, and described transparent shield 9 is fixing on a substrate 2.Described transparent shield 9 is provided with coloured coating.Utilize transparent shield 9 by lateral emitting optical fiber 1 seal protection, effectively dust-proof; Simultaneously can by coating corresponding decorative colors on transparent shield 9, to reach desirable decorative effect.
Described mounting cup 3 and lampshade 6 are respectively arranged with louvre A31 and louvre B61.Heat LED distributed by louvre A31 and louvre B61 is exchanged with extraneous air in time, the service life of prolongation light bar.
