Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention uses an LED as a light source, diffuses the signal light from the light source, and projects it into the surrounding area. This invention relates to a signal notification indicator lamp.

0002

[Conventional technology]

There are many types of signal notification indicators that use LEDs as the light source on the market. It has been designed with a variety of innovations in its structure. This uses LED as the light source. If used, there is no need to replace light bulbs and it is resistant to factors such as vibration. Therefore, conventionally A change from an incandescent bulb light source to an LED light source is being explored.

0003 However, since LEDs emit only a small amount of light, it is necessary to devise ways to compensate for this. That work As a husband, increase the number of LEDs used and use condensing LEDs to improve brightness. , or use various lenses to diffuse the light and increase the size of the light source. Stages were used singly or in combination.

0004 A conventional example is Utility Model Application Publication No. 78770 of 1988. This configuration is An attempt was made to erect LEDs toward the outer periphery and amplify the light source light using a drum-shaped reflective section. It is. In this way, conventionally, it was common to simply install LEDs facing the outer periphery. It was used in When a single LED is installed facing toward the outer periphery, a point-like light source appears to the viewer. Visible. In this embodiment, the light source light is reflected and projected by the drum-shaped reflection part, so it is not visible to the viewer. A linear light source is visible. To widen the visibility range, or to reflect the light source with a drum-shaped reflective part. A diffused type LED is used for reflected light projection. The disadvantage of this is that you need to keep your distance. When visually checking the signal notification indicator lamp, the signal light will be diffused and it will be difficult to see it from a distance. There was a problem with gender.

[0005] Another conventional example is Utility Model Application Publication No. 176214 of 1988, which is a signal We are trying to obtain light from the reflected light of the LED. The composition is a drum-shaped paraboloid of revolution. It consists of an LED held at the focal point of a projecting mirror. However, this configuration is also a paraboloid of revolution. A diffused type LED is used to utilize the reflected light from the reflecting mirror. Therefore, is it far away? There is a problem with poor visibility. Furthermore, the visually recognized light source is also a linear light source. this In addition, if the LED is placed away from the reflective surface, the indicator light will become larger as a whole, and the L If the ED is installed near the reflecting surface, the curved surface of the drum-shaped paraboloid of revolution will become larger. Increase the circumferential direction of the paraboloid of revolution reflector, or reduce the circumferential direction of the paraboloid of revolution reflector. It is necessary to choose whether to lower the reflection efficiency by In any case, the entire signal light There was a growing problem.

[0006] In addition, since LEDs have a directionality of light emission, it is important to note that during the manufacturing process and use, If the axis fluctuates due to vibration etc., the light projection performance will deteriorate and this can be a problem in the signal notification function. It was pointed out that

[0007]

[Problem that the idea aims to solve]

The problem to be solved is visible when configuring the signal notification indicator. Increased light source size and reduced signal light dispersion to improve visibility from a distance It is an object of the present invention to provide a small-sized signal notification indicator lamp.

[0008] In addition, it protects the LED and the board on which the LED is installed, and also holds the LED. The purpose of this is to prevent fluctuations in the light projection axis and maintain light projection performance.

[0009]

[Means to solve the problem]

Therefore, the present invention has developed a light-concentrating type that is installed above and below the pillar installed in the center of the signal notification indicator lamp. LEDs are arranged facing each other, and the point light source is used as a linear light source in the circumferential direction on the reflective surface of the pillar. It is reflected and transmitted through the diffusive lens of the colored transparent globe to form a planar light source to the surroundings. The system was configured to notify the signal light by

0010 In addition, in order to protect the LED and the board on which the LED is installed, A pedestal is integrally provided, and perforations are arranged circumferentially in the pedestal to serve as an LED holding part. A board on which several other LEDs are arranged in a circumferential manner is attached to the stand, and an LED is attached to each stand. It is inserted into and held in the LED holding part of the section.
