Description of the invention: [Technical field to which the invention pertains] The present invention relates to a kind of device, in particular, the two side walls of i in the lenticular lens are the counter-reflecting surface, and the secret shape A concentrating surface is formed to project a linear illumination of the light emitted by the illuminating module into a linear illumination in the direction of the front end of the lenticular lens. [Prior Art] • General museums, Yilin exhibitions, places to record special light projections, and highlight the characteristics of the exhibits. However, the general light emitted by the projection lamp has a higher temperature 'with UV rays', which is likely to cause the exhibits to be pumped after prolonged exposure. The exhibition lighting is generally not suitable for colored lighting. The use of colored lighting will make the exhibits The color of the county has changed. Therefore, the general Lai Ming facilities cannot be fully applied to these exhibitions. At present, all kinds of _ signboards and light boxes are still providing a very attractive and effective advertising medium. Generally, there are many string-connected daylight lamps in the interior to achieve the purpose of night service. However, Riding the required lighting brightness, 'V members use a lot of lamps' is very power-consuming' and most of the electricity is consumed in heat, resulting in waste of resources. Conventional stabilizer lamps need to use a starter to illuminate the fluorescent tube. If only one of the tubes is damaged, the lamps connected in series cannot be activated, and the advertisement H δ is not placed in the commercial floor position. Replace the worn fluorescent tube. Furthermore, the 'lighting lamp' emits a diffused light source, the illumination is not high, and the concentrating ability is 5 1310447. In the 灯, the fluorescent lamp must be densely arranged in the lamp phase to reduce the shadow of the light and shadow. It seems to add the effect of advertising. In addition, the benefits of recycling fluorescent tubes are insignificant, and the mercury in fluorescent tubes can have a significant impact on the pollution of the body and even the health of the human body. Therefore, considering the frequency and maintenance cost of replacing the lamp, the traditional twilight tube is cheap, but the use of the fluorescent tube will cause many hidden concerns in the future, so the development of new lighting equipment has become an extremely interesting industry. Question. • Total reflection in optics delivers light over very long distances without loss of light when reflected by light. The principle of total reflection can be derived from the refraction theorem of light. When the light enters the dense medium from the medium, the angle of incidence will be greater than the angle of refraction. When the light enters the medium from the dense medium, the angle of refraction will be greater than the angle of incidence. The angle of refraction increases as the angle of incidence increases, and the portion of the refracted light decreases as the angle of refraction increases; when the angle of refraction is equal to 90. The incident angle corresponding to this time is called the critical angle of total reflection. When the incident angle is larger than the critical angle, the light line will stop entering the other interface, no more refracted light, and total reflection will occur. Because there is no refraction and it is a reflection, so that all the light is reflected back into the same medium. This phenomenon is called total reflection. The principle of total reflection has been applied in the telecommunications industry as well as on the endoscopes. The fiber is made using this principle. At present, LED has been widely used in facilities with indication function. If the advantages of LED and the principle of total reflection are well combined, the development of new lighting facilities will not only reduce energy waste, but also add a variety of lamps 1310447. Light effect. In order to improve the above-mentioned shortcomings, the lighting device A used for advertising lights is used to generate advertising yarns that are purchased from and recorded, and the inventors have accumulated years of experience and constant The development of the invention has not been produced. SUMMARY OF THE INVENTION The main object of the present invention is to provide a juxtaposition illuminating device which has a (four) stepped cross section by a columnar lens on a vertical and a right side, so that the two side walls form a symmetrical total reflection surface. The light that is totally reflected is vertically projected into a linear illumination toward the front end of the cylindrical lens. A secondary object of the present invention is to provide a linear illumination device which is formed by arranging a condensing surface on the front end of a lenticular lens, and arranging the light passing through the condensing surface toward the front end of the lenticular lens. The concentrating surface is then passed through to concentrate the light within a range of illumination.

The hole in the rear end of the lens 11 can be driven by the electronic control panel to produce a variety of varying lighting effects. The lenticular lens 11 is a closed solid body made of a transparent plastic material such as PolymethylMethacrylate (polymethyl methacrylate). In order to form the symmetrical total reflection surface of the two side walls (1U, (1),) of the lenticular lens 11, the lenticular lens 11 has an equilateral trapezoidal cross section in the plane of the left and right side walls (ln, m,). The light emitted by the illuminating module is divided into two sidewalls of the outer slant when the lenticular lens 11 (refractive index is I.48) with a higher refractive index enters the air of lower refractive index (the refractive index is close to 1). , m,) will make the incident angle of the light accurately greater than or equal to the critical angle of total reflection (that is, the incident angle of the light is greater than or equal to 42.5.), all the self-side walls (1)!
