road lighting device

Abstract

A road lighting device includes a base, an upright pole, a lamp holder, and multiple light sources. The base is fixed to the ground. The upright pole is fixed to the base. The lamp holder is wider at the top and narrower at the bottom, has an upward-facing notch, and is fixed to the top of the upright pole. The lamp holder includes a ring structure. The ring structure is located at the top of the lamp holder. Multiple light sources are disposed on the ring structure and are evenly distributed along the circumference of the ring structure. These light sources emit light outwards in multiple radial directions along the ring structure.

Claims

1. A road lighting device comprising: a base for fixing to the ground; a vertical pole fixed to the base; and a lamp holder, which is wider at the top and narrower at the bottom, has an upward-facing notch, and is fixed to the top end of the vertical pole, wherein the lamp holder comprises: an annular structure located at the top end of the lamp holder; and a plurality of light sources disposed on the annular structure and evenly distributed along a circumferential direction of the annular structure, wherein the light sources are respectively used to emit light outward along a plurality of radial directions of the annular structure.

2. The road lighting device as claimed in claim 1, wherein the lamp holder is rotatable about the central axis of the upright.

3. The road lighting device as claimed in claim 1, wherein when the number of light sources is a specific number, the annular structure is equally divided into the specific number of segments, and any two adjacent segments of the specific number of segments are welded or interlocked with each other.

4. The road lighting device as claimed in claim 1 further comprises: a plurality of light strips disposed on the outer wall of the light fixture.

5. The road lighting device as claimed in claim 1, wherein the lamp holder further comprises: a mounting portion that is fitted onto the top end of the upright pole.

6. The road lighting device as claimed in claim 5, wherein the mounting portion comprises: a first portion; and a second portion disposed on the first portion, wherein both the first portion and the second portion are cylindrical, and the outer diameter of the first portion is smaller than the outer diameter of the second portion, wherein the road lighting device further comprises: a plurality of first light strips disposed on the outer side wall of the light frame; and a second light strip, which is annular and sleeved on the side of the second portion.

7. The road lighting device as claimed in claim 6, wherein the first light strips are full-color light strips and the second light strips are warm light strips.

8. The road lighting device as claimed in claim 1 further comprises: a plurality of mounting bases for fixing the light sources onto the annular structure.

9. The road lighting device as claimed in claim 1, wherein the base includes: a plurality of reinforcing ribs for reducing the tilting moment of the road lighting device.

10. The road lighting device as claimed in claim 1, wherein the base comprises: a base plate having a plurality of fixing holes, wherein the fixing holes are respectively for a plurality of anchor bolts to be inserted therethrough to lock the base plate to the ground.
