ILLUMINATED LAMP-POST.

Application filed January This invention relates to an improved form of street-lamp which serves not only to light the road from the usual height but indicates the presence of the lamp post when a vehicle is in close proximity to it. While the light of a lamp on an ordinary lamp post can be seen from a distance by the driver of a vehicle the lower portion of the post remains unlighted and cannot be easily made out when the vehicle comes in close proximity especially during dark and rainy nights when the hood of a motor car is down. Collisions between vehicles and lamp posts have consequently been recorded, to prevent which an additional or auxiliary lamp has to be provided at the lower end of the lamp post. This not only adds to the cost of lighting but the additional light cannot be seen from all "directions as the pillar obstructs it on one side.

In order to utilize lamp posts for advertisement purposes, it has been proposed to surround the lamp post by a jacket of glass or other transparent material arranged beneath the lamp and to provide an upright conical reflector within the jacket.

The object of the present invention is to prevent accidents by providing a lamp mounted on a hollow frame-work which lamp not only lights the road effectively but also indicates the presence of the lamp post by means of reflecting mirrors adapted to illuminate glass panes (preferably red) fixed on the hollow frame-work at a suitable height from the ground say about four feet. Thus while the top light cannot be seen as the vehicles approach the lamp post, the red or danger light will indicate the presence of the lamp post from all sides and prevent collision.

The invention is shown in the acoompanying drawings in which Figure 1 shows the lamp post in elevation. Figure 2 is a sectional plan on 22, while Figure 3 is aplan on 33.

Referring to Figure 1 a represents a. hol- 9, 1926. Serial No. 80,195.

low four sided lamp post provided with the lamp Z) at the top, and reflecting mirrors 0 a at the lower end about four feet from ground level. lVhile the beams of light from the lamp illuminate the road or street at the required distance on all sides, the beams are also reflected from the mirrors and illuminate the glass panes cl of the lamp post which are close to the mirrors a, a. The mirrors may be placed at an angle or in the form of a pyramid or in the form of a cone so that the light from the lamp is reflected horizontally in all directions instead of any part-icular direction.

It will thus be seen that the improved lamp post not only forms a light elegant and economical structure but serves the double purpose of lighting the road or street and indicating by means of the same light the presence of the lamp post, thus preventing collisions and accidents.

I claim 1. A street lamp post comprising a hollow framework, a street light mounted upon the hollow frame-work, reflecting mirrors mounted within the frame-work for receiving and reflecting light from the street light and glass panes mounted in the frame-work at a suitable height above the ground, and illuminated by light from the reflectors: to indicate the presence of the lamp post base to users of the road.

2. A street lamp post comprising a hollow frame-work, a street light mounted upon the hollow frame-work, reflecting mirrors mounted within the frame-work for receiving and reflecting light from the street light and glass panes mounted in the frame-work about the reflectors at a suitable height above the ground and illuminated by light from the reflectors to indicate the presence of the lamp post base to users of the road.

In witness whereof I have signed this specification dated at Bombay, this 9th day of December, 1925.

ERNEST GORDON CAMERON.
