Description

DETAILED DESCRIPTION OF THE INVENTION (Objective of the Invention) (Industrial Application Field) The present invention relates to a light emitting lamp for safety, security, regulation, etc. on roads, bridges, etc. using a light emitting diode as a light source.

(Prior art) Light-emitting lights for signal lights, signal lights, indicator lights, etc. used for safety, security, and regulation in construction, etc. have traditionally used incandescent light bulbs, but they often break or break. Recently, these light-emitting lamps using light-emitting diodes have appeared due to drawbacks such as being weak against shocks and having poor durability.

Although light emitting diodes have many advantages such as low power consumption, strong impact resistance, and good durability, they are not suitable for light emitting lamps that require omnidirectionality because of their strong directivity.

Therefore, in order to make a light-emitting lamp using light-emitting diodes non-directional or nearly non-directional, it is necessary to arrange a large number of light-emitting diodes so that their light-emitting surfaces are oriented in a plurality of necessary directions over a wide area.

For example, as shown in FIG. 3 and FIG.
The light-emitting surface of ' should be widely disposed on the central substrate or base bar 3' with its light-emitting surface oriented in several directions on the inner surface of the mantle 1'.

(Problem to be solved by the invention) Although it is possible to make the light emitting lamp non-directional or nearly non-directional to some extent by such a device, this device requires the use of a large number of light-emitting diodes. ,
Furthermore, since a large number of light emitting diodes are used, power consumption is also increased, which is an economical problem.

In view of these points, the present invention aims to provide a light emitting lamp using a light emitting diode that is omnidirectional or nearly omnidirectional and is economically advantageous.

(Structure of the Invention) (Means for Solving the Problems) In order to achieve the above object, the luminescent lamp of the present invention includes a light source made of a light emitting diode located inside a translucent mantle so as to be able to conduct electricity. A reflecting mirror with a mirror surface as a diffusely reflecting surface is positioned opposite to this light source, and the light from the light source is irradiated onto the mirror surface of the reflecting mirror, and the reflected light is diffusely reflected into the mantle.

In this configuration, the shape of the mantle is not particularly important, but the preferred shape of the mantle with a wide range of applications is:
A tube-shaped light source is often used to increase the distance as a means of obtaining the irradiation area of a highly directional light-emitting diode. At the same time, the reflecting mirrors with diffused reflection surfaces at the ends are arranged to face each other so that the mirror surfaces face the inside of the mantle, and furthermore, the reflecting mirrors may be positioned in any way at the ends. However, it is convenient to attach it inside a cap that closes off the end of the tubular mantle. Further, if the inner surface of the mantle has a diffusely reflective surface, further effects can be expected.

<Function> When the light emitting diode emits light, the light is irradiated onto a mirror surface that is a diffusely reflecting surface, and the reflected light is diffusely reflected on the inner surface of the mantle, causing the entire mantle shape to emit light.

(Example) Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a sectional view showing an example of the present invention.

1 is a mantle; 2 is a light-emitting diode; the mantle 1 is made of transparent acrylic tubular material, and the inner surface is diamond-cut so that light is diffusely reflected; the light-emitting diode 2 is placed inside the mantle 1; It is arranged on the upper and lower surfaces of a known printed circuit board 3 together with a blinking circuit so that it can be energized from a power source so as to have directivity in the direction of the end of the mantle 1 when it is turned on. Of course, the inner surface of the mantle 1 may be formed so as not to cause diffuse reflection. The light emitting diodes 2 are arranged on both sides of the printed circuit board 3 when the light emitting diodes 2 are arranged on both sides of the printed circuit board 3 when the light emitting diodes 2 are placed in the middle of the outer shell 1, as will be described later. Only . 4 is a cap, 5 is a reflective mirror, and the mirror surface is diamond-cut to form a surface for diffusely reflecting light; the cap 4 is made of rubber, and its inner surface fits with the outer surface of the mantle 1; Reflection using a mirror surface as a diffused reflection surface &
*5 may be directly attached to both ends of the mantle 1, but in this embodiment, it is fitted and fixed inside the cap 4.

The mantle 1 and the cap 4 are the outer surface of the mantle 1 and the cap 4.
This is done by fitting the inner surfaces of the In this embodiment, a plane mirror is used as the reflecting mirror 5 having a diffused reflection surface, and the light emitting diode 2 faces the light emitting diode 2 from the front. It goes without saying that the mirror surface of the reflecting mirror 5 having a diffused reflection surface may be a concave or convex curved surface, or the light emitting diode 2 may be positioned with its directivity tilted with respect to the mirror surface.

The light emitting diode 2 may be arranged inside the envelope 1 by any method, but for example, a fully threaded bolt may be screwed into the center of the printed circuit board 3 on which the light emitting diode 2 described above is arranged so as to be able to conduct electricity. This is done by passing both ends of the fully threaded bolt 6 through the cap 4 in which the reflector 11t5 is integrated. 7 is a nut and 8 is a lead wire. The lead wire 8 is connected to the wiring of the printed circuit board 3 (not shown in the figure because it is complicated). In this embodiment, lead wires 8 are provided on the upper and lower sides, and one is for supplying power to the other.

In this way, a light emitting lamp using a light emitting diode as a light source is formed as a whole.

When the light emitting lamp constructed as described above is energized as shown in FIG. The light is diffusely reflected according to the incident angle of the diffusely reflecting surface, and is diffusely reflected on the inner surface of the mantle 1. If the inner surface is a diffusely reflecting surface, the light is further diffusely reflected, and the entire body emits light.

(Usage example) Such a luminescent lamp is utilized as follows.

〔Effect of the invention〕

Since the present invention is constructed as described above, it has the following effects.

(1) In claim 1, a light source made of a light emitting diode is placed inside the light-transmitting mantle so that it can be energized, and a reflecting mirror with a mirror surface as a diffusely reflecting surface is placed opposite to this light source, so that the light emission does not occur. When the light from the diode is emitted, it is irradiated onto the mirror surface formed as a diffusely reflecting surface of the reflecting mirror 5, and is diffusely reflected according to the incident angle of the diffusely reflecting surface, and is diffusely reflected on the inner surface of the mantle, causing the entire mantle shape to emit light. It is possible to obtain a luminous lamp.

(2) In claim 2, the shape of the mantle is a tubular mantle, the light emitting diode is positioned inside the mantle so as to have directivity in the direction of the end, and the end part has a mirror surface as a diffusely reflecting surface. Since the pIA mirror is positioned so that its mirror surface faces the light emitting diode, it is possible to increase the distance between the light emitting diode and the mirror surface, thereby increasing the irradiation area of the light emitting diode.

■ In claim 3, since the reflector with a mirror surface as a diffused reflection surface is attached to the inside of the cap, it is easy to attach the reflector with a mirror surface as a diffused reflection surface to the mantle, and it is made of rubber as in the embodiment. When the outer surface of the mantle becomes watertight, it is useful for waterproofing.

(2) In claim 4, since the inner surface of the mantle is made into a diffusely reflecting surface, the light reflected on the inner surface can be further diffusely reflected, which is more effective.

■ Despite the strong directivity of the light emitting diode as a whole, a lot of light is emitted because the light from the light emitting diode is irradiated onto the mirror surface formed on the diffusely reflecting surface of the anti-1g mirror, and the diffusely reflected light is diffusely reflected on the inner surface of the mantle. Even without using a diode, it is possible to obtain a light emitting lamp using an omnidirectional or nearly omnidirectional light emitting diode as a light source, which is economically superior.
