Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention is based on direct sunlight.
The present invention relates to a reflector-bulb provided with means for preventing reflected light generated on its outer surface.

[0002]

2. Description of the Related Art As shown in FIG. 8, a reflector-bulb with a front reflector is formed by forming a reflector b on the inner surface of a bulb a by vapor deposition or the like to increase the brightness inside the bulb a. That is, by increasing the luminance in the bulb a, the reflection surface c in the signal lamp can be utilized to the maximum.

[0003]

However, when the signal lamp is turned off, the outer surface of the reflector b of the bulb a receives direct sunlight, so that the reflected light is combined with the reflecting surface c of the inner surface of the signal lamp to form a complex reflection. The result is that abnormal dazzling light is generated on the front of the signal light, especially when the sun is emitted in the morning and evening, the luminance due to the dazzling is maximized, and the luminance close to the luminance when the adjacent signal light is turned on, red, yellow, It is difficult to determine which of the three blue signal lights is on. As a result, not only the vehicles near the intersection but also all the pedestrians make the determination of the blinking of the three-color signal lights erroneous, which causes a problem that many traffic accidents occur every year. Accordingly, an object of the present invention is to provide a reflector-bulb in which an opaque coating film is formed on the outer surface of a reflector of the bulb in order to solve the above-mentioned problems.

[0004]

The above object of the present invention can be achieved by a light bulb having the following structure. That is, the gist of the invention is that in a front reflector-bulb provided in a traffic signal light, a non-reflective surface is formed by painting, printing, or the like over the entire bulb outer surface of a reflector formed on the inner surface of the bulb. Traffic light front reflector-bulb and front reflector provided in traffic signal light
A front reflector for a traffic light, wherein a reflector is formed in a slit shape on the inner surface of the light bulb.
It is a light bulb. Further, by forming a non-reflective surface over the entire outer surface of the bulb of the slit-shaped reflecting mirror, it is possible to more accurately determine the lighting.

[0005]

According to the present invention, as shown in FIG. 6, the reflected light d, d,... Of the light bulb 2 is projected only on the inner surface and does not come out to the outside. The external reflection by the mirror 3 does not appear, and the signal lamp surface has a dark black color when the light bulb 2 is turned off due to the non-reflection surface 4 on the outer surface of the reflecting mirror 3 and is clearly distinguished from the color of the lit signal lamp. When the signal bulb 2 is turned on, the light d,
Due to the complex reflection of d,... on the reflection surface 5 on the inner surface of the signal lamp 1, the lightning increases in brightness, the signal lamp shines brightly, and its color becomes clear and is clearly distinguished from the adjacent turned-off signal lamp. . Next, as shown in FIG.
Is lit, the reflected light d,
.. are combined and reflected on the reflecting surface 5 on the inner surface of the signal lamp 1 and the irradiation light e, e,
Is projected, and the lightning increases the brightness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A front reflector light bulb for a traffic signal according to the present invention will be described below in detail with reference to the drawings showing an embodiment thereof. Embodiment 1 As shown in FIG. 1, a light bulb 2 is provided in the center of a signal light 1. The reflecting mirror 3 is formed on the inner surface of the bulb 2 by a vapor deposition method or the like. Therefore, as shown in FIG. 2, the entire outer surface of the reflecting mirror 3 is coated with an opaque paint, or the non-reflective surface 4 is formed by printing. The color and shading applied to the outer surface of the reflecting mirror 3 are appropriately selected depending on the purpose and effect, but a matte paint is most suitable for preventing reflection. Embodiment 2 As shown in FIG. 3, a reflecting mirror 3 is formed in a slit shape on the inner surface of a light bulb 2 provided at the center in a signal lamp 1 by a vapor deposition method or the like. Third Embodiment As shown in FIG. 4, a reflecting mirror 3 is formed in a slit shape by an evaporation method or the like on the inner surface of a light bulb 2 provided in the center of a signal lamp 1, and the entire outer surface of the reflecting mirror 3 is made opaque. Non-reflective surface 4 applied by paint or printed
Is formed. Also, FIG.
In this case, the reflecting mirror 3 is radially formed on the inner surface by a vapor deposition method or the like. In this case as well, the reflecting mirror 3 is formed in a slit shape, and the non-reflective surface 4 (not shown) is further formed. Is also possible.

[0007]

According to the present invention, as described above, a non-reflective surface is formed on the outer surface of the reflector of a light bulb.
Illuminated light bulbs increase in brightness in particular, and extinguished light bulbs become dark black on the entire surface even when the sun comes out, the difference is large, the lighting color of the signal lamp becomes obvious at a glance by this difference in brightness, This has the effect of preventing traffic accidents.
