Abstract
The utility model discloses an optical fibre backlight lighting device, which is composed of an optical fiber transmission component and a cavity body. The optical fiber transmission component is mainly composed of an optical fiber bundle, the input end is bundled together, and the output end is made into a flat shape and is coupled with the cavity body together. The cavity body comprises a casing, a light wave conductor and a diffusing screen, one side of the inner cavity of the casing is open, and the inner cavity is fixed with the light wave conductor; one side of the light wave conductor is provided with a wave tooth-shaped waveguide combined body along the transmission direction, and the other side is provided with a sand polishing layer. The upper and the lower surfaces of the diffusing screen are sand polishing layers, are covered on the light wave conductor sand polishing side and are fixedly connected with the casing. The utility model has the advantages of simple technology, low cost, even transmitted light, and strong brightness, so the utility model is economical and applicable.
Description
The utility model relates to a kind of illuminating device, and especially a kind of optical fibre illumination device belongs to the lighting source technical field.
Backlight is a kind of novel optical fiber illuminating device that development in recent years is got up, and uses very extensive.For example, be used for detection, electronic device and the inspection of installation site in the circuit board thereof of glass quality.In addition, backlight also can be used for providing illumination for photography, instrument and equipment displaying.From 1979 so far, people have proposed the structural shape and the technology preparation method of multiple backlight.Be typically the most optical fiber is lined up sheet, in the field of illumination optical fiber structure is carried out machinery or chemical treatment makes its light leak.For example, the patent No. is that 4234907,4466697,4519017 United States Patent (USP) all is like this.The shortcoming of this backlight is that manufacture craft is difficult to operation, realizes that difficulty is big.The applying date is that 1993.2.16, application number are that US005187865A, application people have proposed a kind of like this technical scheme for the United States Patent (USP) " BACKLIGHTED PANEL " of FOSTEC company: optical fiber is lined up sheet, in the field of illumination optical fiber cortex is carried out indentation (score), control width of nick and width make its even light leak.The weak point of this backlight is a control difficulty, and emergent light can not evenly throw light on, and because diffusing screen from the distance of optical fiber, thereby makes backlight field of illumination thickness too thick (it is reported and want 12.7 millimeters at least), simultaneously brightness a little less than.
The purpose of this utility model is: at the shortcoming and defect of above-mentioned prior art existence, the optical fiber backlighting arrangement that a kind of manufacture craft is simple, emergent light is even, brightness is strong is proposed, thereby make it with low cost, have good practicality and higher economic results in society.
In order to achieve the above object, optical fiber backlighting arrangement of the present utility model is made up of optical fiber transmission part and cavity two parts, described optical fiber transmission part mainly is made of fibre bundle, its input constriction together, output is made open and flat shape, be coupled with cavity, described cavity comprises housing, light wave guide, diffusing screen, the inner chamber recording quantity of described housing is fixed with light wave guide in the chamber, the one side of described light wave guide is shaped on ripple dentation waveguide assembly along the light transmit direction, another side is the frosted layer, on the described diffusing screen, lower surface is the frosted layer, covers on the frosting of light wave guide, is fixed on the unlimited place of housing.
When the input of the utility model optical fiber backlighting arrangement and light source coupling, light will be transferred in the light wave guide by fibre bundle, penetrate from diffusing screen, thereby be used for illumination or various optical detection.Therefore not only be not difficult to find out that the utility model technology is simple, with low cost, and experiment shows that its emergent light is even, brightness is strong, economy but also be suitable for has good market prospects and economic results in society.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the profile schematic diagram of an embodiment of the utility model.
Fig. 2 is the optical fiber transmission part structural representation of Fig. 1 embodiment.
Fig. 3 is the cavity cross-section structural representation of Fig. 1 embodiment.
Fig. 4 is the structure for amplifying schematic diagram of light wave guide among Fig. 1 embodiment.
Optical fiber backlighting arrangement among Fig. 1 is made up of optical fiber transmission part 1 and the coupling of cavity 2 two parts.Optical fiber transmission part 1 comprises input port 3, fibre bundle 4 and output port 5, wherein input port 3 is made circle, collar is at the constriction end of fibre bundle 4, fibre bundle 4 adopts many components optical fiber, the overcoat pillar, diameter is 7.7 millimeters, and output port 5 is made fan-shaped, and collar is at the open and flat end (referring to Fig. 2) of fibre bundle 4.Cavity 2 is made of housing 6, reflecting layer 7, light wave guide 8, diffusing screen 9.The cavity recording quantity of housing 6 adopts the metallic aluminium manufacturing, and the surface is a black oxide coating, and the inner surface edge pastes reflective aluminum film 7 (referring to Fig. 3).Light wave guide 8 stickers adopt the PMMA lucite to make in housing 6, and it simultaneously is carved with the waveguide assembly 10 of isosceles triangle along light emission direction, and another side carries out frosted (referring to Fig. 4).Diffusing screen 9 adopts the acrylic acid optical plastic to make, and upper and lower surface is the frosted layer, is glued to the opening part of housing 6.
During use, light is transferred to the light wave guide 8 through fibre bundle 4 from input port 3, penetrates from diffusing screen 9 through reflection again.Facts have proved that present embodiment is convenient to suitability for industrialized production, emergent light is very even during use, brightness is extremely strong, can be used as desirable illuminating device.
During concrete enforcement, the utility model can also have many variations.For example, the material of fibre bundle can be glass optical fiber, silica fibre, polymer optical fiber etc.; Reflecting layer in the housing can adopt methods such as spraying, plating, edge subsides to make; Light wave guide can adopt optical glass, optical plastic, even the can transparency liquid is made; The shape of waveguide assembly can be right angled triangle, trapezoid, square, semicircle etc.These variations all drop on protection domain of the present utility model.
