本案は踏切警報機に設置して列車の接近を踏切
通行者に現示予報する警報灯に関する。[Detailed description of the invention] [Industrial field of application] This invention relates to a warning light that is installed in a level crossing warning system and visually warns people passing through the level crossing that a train is approaching.

A level crossing warning system is a device that warns people passing by a level crossing that a train is approaching and warns them to stop passing.As shown in Figure 4, a level crossing warning system uses a warning bell (or warning sound generator).
1. X mark warning sign 2. Flashing red warning light 3.
It consists of a train direction indicator 4 and a steel pipe column 5 that supports these.
警報灯３は一対の灯器からなり、上り列車又は
下り列車の接近条件によつて交互に点灯し、赤色
散光レンズを内側より照明する白色電球を有する
ものである。 The warning light 3 consists of a pair of lamps, which are turned on alternately depending on the approaching conditions of an inbound or outbound train, and have a white light bulb that illuminates a red diffused lens from the inside.
ところが、点灯表示の照明具として従来は主と

があつた。
However, conventionally, 24V20W white light bulbs have been mainly used as lighting equipment for lighting displays, and their power consumption cannot be ignored, and their lifespans end in a relatively short period of time, and they can break due to unforeseen circumstances. Therefore, its maintenance and management required a troublesome effort. For example, light bulbs are required to be replaced at regular intervals, such as once every two years, even if they are not broken. On the other hand, a sturdy structure is used as a lamp house for outdoor use or because it is necessary to prevent the effects of vibration, which has the disadvantage of increased weight.
この欠点を解消する目的で、照明具として発光
ダイオードを用いるという試みがある。 In order to overcome this drawback, attempts have been made to use light emitting diodes as lighting devices.

題があり、警報灯には必ずしもLEDの特長を十
分に生かすことができない。 By using small light-emitting diodes (hereinafter referred to as LEDs) in the lighting fixtures, they are free from breakage due to vibrations, are small, lightweight, have low power consumption, and are easy to maintain. However, simply replacing white light bulbs with multiple LEDs does not provide enough light, and since the display is flat, there is a problem that visibility from the front cannot be achieved. cannot necessarily make full use of the features of LEDs.
本案の目的は照明具にLEDを用いた警報灯に
好適な構造を提供することにある。 The purpose of this project is to provide a suitable structure for a warning light using LED as a lighting device.

In this case, a board with a set of light emitting diodes with different brightness in the central area and the peripheral area facing the lens is placed inside a case whose front side is covered with a diffuser lens to form a storage space for the light emitting diodes. This is a warning light in a railroad crossing warning system, characterized in that a reflective surface is attached to the inner circumferential surface of the body of the case, and the case is removably attached to the lamp body of the warning light.

７ａの組を設置する。 In FIGS. 1 and 2, a board 8 has an LED 7 mounted inside a circular hollow case 6 with an open front.
Store and install. Although the arrangement of the LEDs 7 mounted on the board 8 is not particularly limited, the case 6
Evenly and densely arranged horizontally and vertically or concentrically throughout the interior. Each LED 7 is connected in series or in series and parallel to the power supply wiring, but a set of LED 7 is connected to the central area,
Separate LEDs in each area concentrically with the surrounding area, and set 7 sets of red-emitting regular LEDs (for example, 200mcd) for the peripheral area, and use red-emitting high-intensity LEDs in the central area. (e.g. 500mcd)
