Abstract

An illumination device includes a body. The inner space of the body is divided into two parts as a first part and a second part. A heat dissipating module is disposed in the first part. The second part is fully sealed so that dusts, water and insects may be kept off. A plurality of light emitting units are disposed in the second part so as to provide light. The light emitting units are connected with the heat dissipating module in the first part. Hence, heat generated by the light emitting units may be dissipated out of the body and so that the illumination device of the present invention may have a longer service life.

Claims

1. A heating dissipating pole illumination device, comprising a body and an L-shaped pole connected with the body, wherein the body includes:

an upper cover;

a lower cover, which is transparent and engaged with the upper cover in a very tight manner;

a dividing plate, which is disposed between the upper cover and the lower cover to divide an inner space of the body into two parts as a first part formed in the upper cover and a second part formed in the lower cover;

a heat conducting plate, which is fitted onto an opening of the dividing plate and extends into the second part;

a plurality of light emitting units located in the second part, which are fitted on a bottom Surface of the heat conducting plate;

a heat dissipating module located in the first part, which is disposed above a top surface of the heat conducting plate; and

a heat guiding piece with one end connected to the heat conducting plate and the other end connected to the heat dissipating module so that heat generated by the light emitting units is transmitted to the heat dissipating module and is dissipated out of the body.

2. The heating dissipating pole illumination device as in claim 1, wherein a plurality of venting slots are formed on each side of the upper cover.

3. The heating dissipating pole illumination device as in claim 1, wherein the heat dissipating module includes at least one set of heat dissipating fins and a fan and wherein one end of the heat guiding piece is connected with the heat conducting plate and the other end is penetrated through the heat dissipating fins, the fan being disposed to the heat dissipating fins.

4. The heating dissipating pole illumination device as in claim 3, wherein the heat guiding piece has an U shape.

5. The heating dissipating pole illumination device as in claim 1, wherein the light emitting units are light emitting diodes.

6. A heating dissipating pole illumination device, comprising a body and a straight pole connected with the body at top, wherein the body includes:

an upper cover;

a lower cover, which is transparent and engaged with the upper cover in a very tight manner;

a dividing plate, which is disposed between the upper cover and the lower cover to divide an inner space of the body into two parts as a first part formed in the upper cover and a second part formed in the lower cover;

a heat guiding piece penetrated through the dividing plate to have one end extended into the first part and the other end into the second part

a heat dissipating module, which is disposed in the first part to be mounted on the heat guiding piece;

a heat conducting plate, which is disposed in the second part to be mounted on the heat guiding piece; and

a plurality of light emitting units, which are fitted on the heat conducting plate so that heat generated by the light emitting units is transmitted via the heat guiding piece to the heat dissipating module and then is dissipated out of the body.

7. The heating dissipating pole illumination device as in claim 6, wherein the heat guiding piece has a straight tabular shape.

8. The heating dissipating pole illumination device as in claim 6, wherein the heat dissipating module includes at least one set of heat dissipating fins and a fan and wherein the heat guiding piece is penetrated through the heat dissipating fins, the fan being disposed to the heat dissipating fins.

9. The heating dissipating pole illumination device as in claim 8, wherein the heat dissipating module includes two or more sets of heat dissipating fins and fans.

10. The heating dissipating pole illumination device as in claim 6, wherein a cross section of the heat conducting plate is polygonal or rectangular.

11. The heating dissipating pole illumination device as in claim 6, wherein the light emitting units are light emitting diodes.

12. The heating dissipating pole illumination device as in claim 6, wherein a plurality of venting slots are provided on each side of the upper cover.
