Abstract

A roadside lamp with a heat dissipating design is disclosed. The roadside lamp of the present invention comprises a seat portion and a plurality of light emitting units. A panel is fitted to the seat portion and the light emitting units are fitted to the panel. The back portion of the panel is tightly fitted to a heat dissipating fin-like portion. A pair of rails extends outwardly from the fin-like portion. The pair of rails may be used to connect the roadside lamp with a surface in a place such as a tunnel. For example, a track may be provided on the top portion of a tunnel; therefore, a plurality of the roadside lamps may be fitted to the track in a tidy manner. The pair of rails allows each roadside lamp to be fitted to the track and thus, the location of the lamp may be adjusted.

Claims

1. A roadside lamp with a heat dissipating design, comprising:

a seat portion, wherein a panel is fitted to the seat portion and light emitting units are fitted to the panel, and wherein the back portion of the panel is tightly fitted to a heat dissipating fin-like portion and a pair of rails extends outwardly from the fin-like portion; and

a plurality of light emitting units,

characterized in that the pair of rails may be used to connect the seat portion with a track provided on the top portion of a tunnel.

2. The roadside lamp as in claim 1, wherein a sealing portion is disposed at either end of the seat portion to seal the two ends.

3. The roadside lamp as in claim 2, wherein a power supply device or a power source and a circuit is provided inside the sealing portion to provide electricity.

4. The roadside lamp as in claim 2, wherein a connective portion is provided on the inner side of each sealing portion and can connect with the edge of the fin-like portion to hold the latter in position, and wherein several holes are provided in the fin-like portion and each sealing portion to facilitate the use of screws.

5. The roadside lamp as in claim 2, wherein a connective tube may be provided on the sealing portion to connect the seat portion to a regular lamppost.

6. The roadside lamp as in claim 1, wherein the light emitting units may be LED'"'"'s.

7. The roadside lamp as in claim 1, wherein the panel is a module made separately according to the actual number of the LED'"'"'s so as to achieve easy manufacturing and easy maintenance of the roadside lamp of the present invention.

8. The roadside lamp as in claim 1, wherein a connective unit may be provided on the pair of rails or other location of the seat portion and the angle of the connective unit may be adjusted longitudinally or transversely.

9. The roadside lamp as in claim 1, wherein five light emitting units are fitted to the panel in a symmetric manner, and wherein a first light emitting unit is centrally disposed and a second light emitting unit is disposed on either side of the first light emitting unit and the angle between them is 32.5±

5 degree, and wherein a third light emitting unit is disposed by either of the two second light emitting units and the angle between the former and the first light emitting unit is 55+5 degree.
