SUMMARY OF THE INVENTION
The present invention relates to a heat dissipating apparatus (for lamp) that can prevent the damages caused by dusts, water, insects, corrosion and erosion.
The present invention also relates to a heat dissipating apparatus (for lamp) that can prevent the accumulation of dusts and wherein the heat dissipating pieces extend downwards or sideways so as to enhance the heat dissipating capacity by the ambient cold air rising upwards and to keep other undesirable factors (such as dusts) off.
The present invention further relates to a heat dissipating apparatus (for lamp) wherein an AC/DC adopter unit is used to supply DC (direct current) to the light generating units so as to be more economical (because no battery is needed).
The present invention further relates to a heat dissipating apparatus (for lamp) wherein a programmable timer and sensor circuit and an overheating protection circuit are disposed in an AC/DC adopter unit so as to turn off or on the light generating units and protect the light generating units from overheating.
The heat dissipating apparatus of the present invention comprises a supporting rod and a main body. The main body includes a heat dissipating unit, a light generating units plate, one or more heat conducting pieces, an AC/DC
adopter unit and a cover. The light generating units plate is fixedly fitted to an opening at the central portion or other appropriate location of the heat dissipating unit so that the light generating units point downwards or sideways. The AC/DC adopter unit is fitted on top of the heat conducting pieces. The cover is fitted on top of the heat dissipating unit. The cover seals up the top portion of the heat dissipating unit, and hence a sealed space is formed. The light generating units plate, AC/DC
adopter unit and heat conducting pieces are disposed in the sealed space. When heat is generated by the light generating units, heat is transferred to the light generating units plate and the heat conducting pieces and then to the heat dissipating unit and the heat dissipating pieces. Heat is then dissipated into the ambient air. In addition, because the heat dissipating pieces of the heat dissipating unit extend downwards, dusts will not accumulate on them (so that their heat dissipating capacity will not be reduced) so that such lamp may have a longer service life.
According to an aspect, the invention provides for a heat dissipating system for a lamp, comprising:
a heat dissipating unit;
a light generating units plate;
one or more heat conducting pieces; and a cover, wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Please see Figs. IA, 113 and 2 for the first embodiment of the present invention. The first embodiment of the heat dissipating apparatus comprises a heat dissipating unit 11, a light generating units plate 12, one or more heat conducting pieces 16 and a cover 17.
An opening (not shown in the drawings) is provided at the central portion or other appropriate location of the heat dissipating unit 11. The top surface may be a planer surface or other type of surface, and a plurality of heat dissipating
4 pieces 111 downwards extend from the bottom side of the heat dissipating unit 11.
The heat dissipating pieces 111 may have the shape of a cylindrical rod (as illustrated in Figs. IA and I B) or the shape of a flat rectangular sheet (as illustrated in Fig. 2) or other shape. The heat dissipating pieces 111 point downwards or sideways so that dusts, birds' droppings and nests, etc. will not fall and accumulate on the pieces 111 so that their heat dissipating capacity will not be reduced and their heat dissipating capacity may be enhanced by the ambient cold air rising upwards.
A plurality of light generating units are fitted on the light generating units plate 12. The light generating units plate 12 may be made of aluminum or other types of highly conductive metals. The light generating units 13 may be fitted on the underside or wide walls of plate 12. The light generating units 13 may be LED, OLED or other types of light generating units. Also, a cover is fitted on top of the light generating units 13. The plate 12 is fixedly fitted by fasteners 15 to an opening at the central portion or other appropriate location of the heat dissipating unit 11 so as to seal up the opening and so that the light generating units 13 fitted on the underside of plate 12 may point downwards or sideways.
A portion of each heat conducting piece 16 is in contact with the top surface of the light generating units plate 12, and other portions are in contact with the top surface of the heat dissipating unit 11. The heat conducting pieces 16 may be heat-conducting tubes or heat-conducting flat sheets.
The cover 17 may have the form of a lampshade. The cover 17 is fitted on top of the heat dissipating unit 11. The cover 17 seals up the top portion of the heat dissipating unit 11, and hence the light generating units plate 12 and the heat conducting pieces 16 are sealed from the ambient surroundings so that they will
The heat dissipating pieces 111 may have the shape of a cylindrical rod (as illustrated in Figs. IA and I B) or the shape of a flat rectangular sheet (as illustrated in Fig. 2) or other shape. The heat dissipating pieces 111 point downwards or sideways so that dusts, birds' droppings and nests, etc. will not fall and accumulate on the pieces 111 so that their heat dissipating capacity will not be reduced and their heat dissipating capacity may be enhanced by the ambient cold air rising upwards.
A plurality of light generating units are fitted on the light generating units plate 12. The light generating units plate 12 may be made of aluminum or other types of highly conductive metals. The light generating units 13 may be fitted on the underside or wide walls of plate 12. The light generating units 13 may be LED, OLED or other types of light generating units. Also, a cover is fitted on top of the light generating units 13. The plate 12 is fixedly fitted by fasteners 15 to an opening at the central portion or other appropriate location of the heat dissipating unit 11 so as to seal up the opening and so that the light generating units 13 fitted on the underside of plate 12 may point downwards or sideways.
A portion of each heat conducting piece 16 is in contact with the top surface of the light generating units plate 12, and other portions are in contact with the top surface of the heat dissipating unit 11. The heat conducting pieces 16 may be heat-conducting tubes or heat-conducting flat sheets.
The cover 17 may have the form of a lampshade. The cover 17 is fitted on top of the heat dissipating unit 11. The cover 17 seals up the top portion of the heat dissipating unit 11, and hence the light generating units plate 12 and the heat conducting pieces 16 are sealed from the ambient surroundings so that they will
5 not be affected or damaged by dusts, water, insects, corrosion and erosion.
Now, please see Fig. 3, which illustrates the first embodiment of the present invention in operation. When heat is generated by the light generating units 13, heat is transferred to the light generating units plate 12 and the heat conducting pieces 16 and then to the heat dissipating unit 11 and the heat dissipating pieces 111. Heat is then dissipated into the ambient air. In this way, heat may be dissipated quickly so that the light generating units 13 will not be damaged by overheating.
In addition, because the light generating units plate 12 and the heat conducting pieces 16 are in a sealed space and the heat dissipating pieces 111 point downwards or sideways, no dusts will accumulate on light generating units plate 12, the heat conducting pieces 16 and the heat dissipating pieces 111;
therefore, a high efficiency of heat dissipation may be ensured.
Now, please see Fig. 4, which illustrates a third embodiment of the present invention. The design of the third embodiment is similar to the first embodiment illustrated in Figs. 1 A and 1 B except that an AC/DC adopter unit 18 is used in the third embodiment. The AC/DC adopter unit 18 is fitted on top of and in contact with the heat conducting pieces 16 so that heat generated by the AC/DC adopter unit 18 and a sensor circuit may be transferred to the heat conducting pieces and then to the heat dissipating unit 11 and the heat dissipating pieces 111.
Heat is then transferred to the ambient air. In this way, the AC/DC adopter unit 18 may have a longer service life.
The AC/DC adopter unit unit 18 serves to convert the AC supplied from an electrical outlet to DC; then the DC (direct current) is fed to the light generating units 13. In addition, a programmable timer and sensor circuit and an overheating
