Description

[Detailed Description of the Invention] The diffused warning light of the present invention will be explained in detail according to the following items.

A. Industrial field of application B. Overview of the invention C. Prior art [Figures 9 and 10] D. Problems that the invention attempts to solve [Figures 9 and 1]
[Figure 0] E Means for solving the problem F Example [Figures 1 to 8] a Glove, base, etc. b Diffusing unit c Function G Effect of the invention (A Field of industrial application) The present invention is novel. Regarding diffused warning lights. Specifically, a diffused light warning light is provided with a rotating reflector and a fixed reflector in a translucent globe, and the light from the rotating reflector is reflected by the fixed reflector.
The objective is to improve the visibility of the light reflected by the fixed reflector so that the light reflected by the fixed reflector can be seen from a wider range.

(B Overview of the invention) The diffused light warning light of this invention divides the reflecting surface of a flat synthetic resin fixed reflecting mirror into a number of small reflecting surfaces, and reflects the light from the rotating reflecting mirror approximately toward the front. By using a mixture of small reflective surfaces that reflect in directions that are tilted to the left and right with respect to the front, the light reflected by the fixed reflector is reflected not only in the direction facing approximately the front but also in the direction directly in front of the front. The light reflected by the fixed reflector can be seen not only from a limited direction but also from a wider range, improving visibility by emitting light in directions tilted to the left and right. It is something.

(C. Prior Art) [Figs. 9 and 10] Figs. 9 and 10 show an example a of a conventional diffused light warning light.

b is a glove mounted on the roof of a car, and is made of transparent synthetic resin and formed into a cylindrical shape.

c is a light scattering unit disposed within the globe b.

d is a reflecting section, and two reflecting mirrors e and e are connected back to back. The reflecting surfaces f, f of these reflecting mirrors e, e have a paraboloid of revolution shape, and are coupled so that their focal points are at a common point.

g is a light bulb, the filament h of which is located at the focal point of the reflecting surfaces f, f. Therefore, the light emitted from the filament h and reflected by the reflecting surfaces f, f is irradiated as a parallel light beam.

i is a rotating plate, and the reflecting portion d is connected to the rotating plate i.
is placed on top. Therefore, when the rotating plate i rotates, the reflecting part d rotates and the orientation of the openings of the reflecting surfaces f, f sequentially changes in the rotating direction, so that the light irradiated by the light scattering unit c rotates and The diffused warning light a can be seen as a flash by those around it.

j is a fixed reflecting mirror fixed at a position adjacent to the rotary plate, and its parallel reflecting surface K faces obliquely to the front.

Therefore, when the lights l, l,... emitted from the rotating reflectors e, e are irradiated onto the reflective surface K of the fixed reflector j, the lights l, l,... are reflected toward the front. . Since the reflecting surface K of the fixed reflecting mirror j is intermittently irradiated with the lights l, l,... from the rotating reflecting mirrors e, e, when the reflecting surface K of the fixed reflecting mirror j is viewed from the front, the corresponding The reflective surface K is visually recognized as blinking.

(D. Problem that the invention aims to solve) [Figure 9,
[Fig. 10] By the way, in the above-mentioned diffused light warning lamp a, the reflecting surfaces f and f of the rotating reflectors e and e are paraboloids of revolution, and the light source (the filament h of the light bulb g ), the light reflected by the reflecting surfaces f, f becomes a parallel beam of light. Since the reflecting surface K of the fixed reflecting mirror j has a planar shape, it only reflects the light coming from the rotating reflecting mirrors e and e toward the front as a parallel beam of light, so that There is a problem in that the light reflected by the fixed reflector j can only be seen visually, and the light reflected by the fixed reflector j cannot be seen from a position even slightly deviated from the lateral direction.

(E Means for Solving the Problems) In order to solve the above problems, the diffused warning light of the present invention uses a flat synthetic resin fixed reflector that reflects the light from the rotating reflector toward the front. The reflective surface is divided into a large number of small reflective surfaces, with a mixture of small reflective surfaces that reflect the light from the rotating mirror toward the front and small reflective surfaces that reflect the light in directions tilted to the left and right with respect to the front. It is something.

Therefore, in the diffused warning light of the present invention, the light reflected by the fixed reflector is emitted not only in the direction facing approximately the front, but also in directions tilted to the left and right with respect to the front. The reflected light can be seen not only from a limited direction but from a wider range, and the visibility is significantly improved.
