があるなどの不便があつた。 Fluorescent discharge lamps are the most popular conventional lighting equipment, but although fluorescent lamps generate considerably less heat than incandescent light bulbs, they still dissipate a considerable amount of heat, so they can be used, for example, in refrigerators and refrigerators. It is unsuitable for installation and use in a cold atmosphere such as in a cold atmosphere, and if it is installed and used in a place that is exposed to the rain such as an advertising sign lamp or a place that is easily affected by moisture such as in a refrigerated case for fresh fish,
The drawback was that electrical problems such as poor electrical insulation and poor lighting were likely to occur. Furthermore, when installed in a show window or a show case, there is an inconvenience in that it may be necessary to provide a shade member such as a shade to block the illumination light from the customer's view.

招くなどの問題があつた。 There have also been attempts to emit light transmitted within a conventional light guide in a direction transverse to the axis of the light guide to create illumination light, but with conventional structures, the illumination light has no directionality, so a light shielding member is used. If it is necessary to install a (reflective member) or try to provide directivity,
There were problems such as the manufacturing process became complicated, resulting in high costs, and when used outdoors, quality and performance deteriorated quickly.
本発明は、このような従来の問題点を一掃する

あまり期待できず、好ましくない。 In the figure, 1 is an optical transmission rod that transmits light incident from one end to the other end.
It is necessary to use materials with as high transparency and good light resistance as possible, such as quartz glass rod (refractive index: 1.46), optical glass rod (refractive index: 1.5 to 1.7), and silicone resin rod (refractive index: 1.41). A selection of these is used. Rod 1
is solid and has a circular cross section, and its central axis may be either a straight line or a curved line, and the figure shows a straight line. The dimensions of the rod 1 may be appropriately determined depending on the amount of light to be transmitted, the length of the illumination line, etc. For example, the diameter may be appropriately selected from a range of about 3 to 30 mm, preferably from a range of about 5 to 20 mm. Ru. If the diameter is smaller than 3 mm, the light-receiving area will be small and there is a risk of light reception loss, and if the diameter exceeds 30 mm, the price will rise, but little improvement in quality and performance can be expected, which is not desirable.

合）することができる。 Diffusion stripes 2 for diffusing and reflecting transmitted light into the rod 1 are formed on the outer peripheral surface of the light transmission rod 1. This diffusion stripe 2 is composed of transparent fine powder with a higher refractive index than the rod 1 and light resistance, and silicone rubber or silicone resin with a lower refractive index than the fine powder and mixed into the fine powder as a binder. Examples of such fine powder include barium sulfate (refractive index: 1.51), magnesia (refractive index:
1.8), titania (refractive index: 2.6), etc. can be advantageously used. The fine powder can be mixed with Zns (blue-green) or Eu 2 O 3 (red) and Tb 2 O 3 (green) for thermal diffusion in order to give any color to the reflected and diffused light if necessary. Therefore, it can be mixed (for example, in the case of magnesia and titania).

均一な厚さになるように塗布する。 An example of means for forming the diffusion stripes 2 on the rod 1 is as follows. Silicone rubber stock solution with added vulcanizing agent (product name OF106,
Fine titania powder (average particle size 2000-4000 mesh) is added to OF103 (manufactured by Shin-Etsu Silicone Co., Ltd.) and stirred well to prepare a coating material for forming diffusion stripes whose overall viscosity is syrup-like. Next, the diameter is 10mm,
A slit with a width of 2 mm is left in the axial direction of the outer surface of a 2 m long quartz rod, which is masked with masking tape, and the above-mentioned coating material is applied to this slit part so as to have as uniform a thickness as possible.

記微粉体の屈折率より小さい。 Next, after vulcanizing the silicone rubber at a temperature of 140° C. for about 20 minutes, the masking is removed to obtain the rod 1 on which the diffusion stripes 2 are integrally formed. Incidentally, when silicone resin is used instead of silicone rubber, the diffusion stripes 2 can be formed by the same process. The diffusion stripes 2 formed in this way are composed of fine powder with different high and low refractive indexes and silicone rubber or silicone resin, so they are cloudy and hardly transmit any light, and are substantially It becomes opaque to light. The refractive index of silicone rubber or silicone resin is 1.41, which is smaller than the refractive index of the above-mentioned fine powder.

有利には1.5〜2.5mm程度である。 The diffusion stripes 2 are formed continuously or intermittently in the axial direction of the rod 1, and can have any shape such as a straight line, a curved line, or a spiral shape, and a straight line is shown in the figure. If the thickness of the diffusion stripes 2 is too thin, there is a risk of transmission loss, so it is necessary to form the diffusion stripes 2 to a thickness of at least 0.1 mm or more. The width of the diffusion stripes 2 is appropriately determined depending on the amount of incident light, the diameter and length of the rod 1 (illumination line length), and the like. Generally speaking, as the width of the diffusion stripes 2 increases, the brightness of the illumination light increases, but on the other hand, the length of the illumination line decreases;
Although the length of the illumination line increases, the brightness of the illumination light decreases, so the width may be appropriately determined depending on the use and purpose of the illumination device. When the width of the diffusion stripes 2 is constant, the brightness of the illumination light decreases exponentially with the distance from the incident end, so in order to compensate for this decrease, the width of the diffusion stripes 2 is It is also possible to adopt a means of gradually increasing the amount from the incident end side. This can also be achieved by forming a reflecting mirror section 3 on the end face of the rod 1 on the output end side and reflecting the transmitted light that has reached the output end toward the input end. This reduction can be compensated to some extent. As mentioned above, the width of the diffusion stripes 2 varies depending on the rod length, diameter, amount of incident light, and the use and purpose of the lighting equipment, but is usually 0.5 to 3.0 mm.
Advantageously it is of the order of 1.5-2.5 mm.

This seal prevents the intrusion of rainwater and contaminants such as dust into the circumferential surface 5, and the outer circumferential surface of the rod 1 can be kept clean forever. The protective tube 4 may be made of any material as long as it is transparent and has light resistance and appropriate mechanical strength; for example, materials made of transparent glass or fluororesin can be advantageously used.

於て矢符７は光の放出方向を示す。 FIG. 3 schematically shows one usage situation of the lighting device of the present invention. As is clear from FIG. 3, in its use, light from a light source a such as a halogen lamp, mercury lamp, or xenon lamp is focused by an optical system, for example, a reflecting mirror b, and is directed to the incident end face of the rod 1. The incident light is transmitted in the axial direction while repeating total reflection within the rod 1. Along the axial direction, the outer peripheral surface of the rod 1 has a substantially light-opaque diffusion stripe 2 made of fine powder with a high refractive index and silicone resin or silicone rubber with a lower refractive index than the fine powder. is formed, so the light transmitted inside rod 1 is
During transmission, the light is diffusely reflected into the rod 1 by the diffusion stripes 2, and is then directionally emitted in a direction opposite to the diffusion stripes 2 due to the lens action of the rod 1. In FIG. 3, arrow 7 indicates the direction of light emission.

放出されるものと考えられる。 Figure 4 is an explanatory diagram showing the principle of the lens action of the rod 1. Of the light diffusely reflected by the diffuser stripe 2, the angle of the light diffused within a range of about ±40° is reduced by the lens action of the rod. It is emitted in the opposite direction to the stripe 2 and becomes illumination light. It is considered that the diffused light whose diffusion angle exceeds ±40° undergoes repeated total reflection within the rod 1, is again diffusely reflected by the stripes 2, and is emitted to the outside of the rod 1.

有用である。 As described above, the lighting device of the present invention uses a method in which light is transmitted by the rod and used as illumination light by diffused reflection of the diffused stripes, so in addition to not generating any heat, There is no need to consider electrical insulation at all, there is almost no adverse effect from rainwater or water vapor, and the light is emitted directionally due to the lens action of the rod, so it is superior to conventional products. It is possible to provide a lighting device with a simple structure and an innovative design without requiring the installation of a shade member such as a shade as seen in the above. Furthermore, since the diffusion stripes are composed of fine powder with a particularly high refractive index and silicone rubber or silicone resin with a lower refractive index, the diffusion stripes can be formed by extremely simple means such as coating and curing, making it easy to manufacture. In addition to being easy and inexpensive to provide, silicone rubber or silicone resin has excellent light resistance, heat resistance, and rubber-like elasticity, so even when installed outdoors, it can be used for a long time without deterioration or peeling, and has excellent durability. It is particularly useful for use in show windows, show cases (particularly frozen and refrigerated show cases), and various advertising sign lights.
