Description

[Detailed description of the invention] This invention is an improvement on street lights and other under-seat displays that display lot numbers, emergency exits, etc.

Conventional electric lampshades are suitable for illuminating the area below because they can effectively utilize light, but above the electric lampshade, for example, towards the ceiling, the electric lamp light is completely lost.

However, in general, street lamp lot number displays and corridor emergency exit displays are often located above the shade, and are particularly desirable and effective as indicators, but total reflection type, such as aluminum shade, which has good reflection efficiency, are not suitable for this purpose. There was a drawback that it could not be used in such cases.

The present invention eliminates these drawbacks and improves the effect by illuminating the display with electric lamp light in a spot-like manner.

Next, an embodiment applied to the street light shown in the drawings will be described in detail.

Reference numeral 1 designates a street light pole, to which a downward-facing electric light 2 is connected via a socket 3 with a bracket 4 so as to illuminate the road surface.

A display board 5 displaying a lot number and the like is fixed to the lever bracket 4 using a mounting tool 4'.

A lampshade 6 made of aluminum acid with good reflection efficiency for the electric lamp 2 is clamped with a backing 8 interposed between the socket 3 and the nut 7, as shown in an example in FIG. An elastic ring 9 is provided so as to be in contact with the surface of the electric lamp 2, and the backing 8 and the elastic ring 9 prevent rainwater, dust, etc. from entering the socket 3.

The mounting position and shape of the display board 5 may be determined as appropriate, but the display board 5 should be located above the lampshade 6, which provides good display efficiency.

However, in the present invention, a part of the electric lantern 6 is cut out to create a transparent window 1.
0 is formed, and reflecting plates 11 are formed on both side edges of this window 10.

The reflecting plates 11 are shown as being formed on both sides of the window 10 to illuminate the front and back surfaces of the display board 5, but when the entire periphery or only one side of the display board 5 is illuminated, only one side edge may be used.

Further, the window 10 can be angled, round, or other suitable shapes.

This transparent window 10 is tightened and fixed at an appropriate position with respect to the display board 5 with a nut so that the light passing through the transparent window 10 hits the front stone plate 5 in the best possible manner.

Therefore, the lamp light passing through the transparent window 10 is not scattered, but is effectively reflected by the reflector 11, and like a spot, it stands out in the dark area blocked by the shade 6 and attracts attention, and most of the electric lamp light is totally reflected. The shaped shade can effectively illuminate the downward direction and also illuminate the display board.

Claims (1)

[Scope of utility model registration request] In a lighting device that has a transparent window in the electric lantern in order to illuminate a display board located above the electric lantern, the display board is attached to a bracket that supports the device, and the electric lantern is attached to the tip of this bracket. A translucent window is cut out in a part of the electric lampshade through which the electric lamp light illuminating the display board passes, and the electric lamp light is reflected toward the display plate at the edge of the transparent window. A lighting fixture with a curved reflector that protrudes from the outside of the lampshade.
