LIGHT-EMITTING DIODE ILLUMINATING
EQUIPMENT WITH HIGH POWER AND HIGH HEAT
DISSIPATION EFFICIENCY
BACKGROUND OF THE INVENTION
1. Field of the invention The invention relates to a light-emitting diode (LED) illuminating equipment, and particularly relates a LED illuminating equipment with high power and high heat-dissipation efficiency, and the LED illuminating equipment has a structure equipped with water-proof, heat-isolation, and uniform heat distribution.

DISSIPATION EFFICIENCY
BACKGROUND OF THE INVENTION
1. Field of the invention The invention relates to a light-emitting diode (LED) illuminating equipment, and particularly relates a LED illuminating equipment with high power and high heat-dissipation efficiency, and the LED illuminating equipment has a structure equipped with water-proof, heat-isolation, and uniform heat distribution.
2. Description of the prior art Because LED has advantages of low power consumption, shock-proof, fast response, and suitability for mass production, the research and development of the lighting equipment with the LED is continuously being carried on. Please refer to FIG. IA and FIG. 1B. FIG. IA is a front view of an illuminating equipment with a number of LEDs arranged into a matrix. FIG. 113 is a cross-section view of the illuminating equipment shown in FIG. 1A along W-W line. As shown in FIG. IA
and FIG. 1B, the illuminating equipment provides brighter illumination by a number of LEDs arranged into a matrix, such that the illuminating equipment is suitable for the illumination application. However, the development of the illuminating equipment mostly focuses on how to control the direction of light to achieve higher brightness, not on how to conduct heat or dissipate heat, as shown in US
patent No.
6554451. Currently, if the high-power LED continuously lights for a period of time, a problem of over-heat occurs; further, the lighting efficiency of the LED
decreases and the brightness of the LED can not be raised. It is thus indicated that high-power LEDs in every application needs a mechanism for quickly conducting or dissipating heat. In addition, when the illuminating equipment is in operation, the traditional illuminating equipment with a number of LEDs generates a problem of non-uniform heat-distribution. As a result, the LEDs disposed inside the illuminating equipment and exposed under the heat-impact have a decaying opto-electrical efficiency. Furthermore, if the heat generated by the LEDs in operation can not be effectively isolated to prevent the heat from being radiated or conducted to a light emitting area, the lighting efficiency of the LEDs will be lowered under the heat-impact generated by them.
Accordingly, a scope of the invention is to provide a LED illuminating equipment with high power and high heat-dissipating efficiency. Particularly, according to the LED illuminating equipment of the invention, a heat-conducting structure of the LED
illuminating equipment can quickly and uniformly distribute the heat generated by the LEDs in operation and effectively isolate the heat out of the illuminating area.
Besides, the illuminating equipment with a number of high-power LEDs needs a water-proof design in an outdoor environment, for example, a streetlamp.
Therefore, another scope of the invention is to provide a LED illuminating equipment with high power and high heat-dissipating efficiency; particularly, the LED
illuminating equipment has a water-proof design.

According to a preferred embodiment of the invention, a LED illuminating equipment includes a heat-dissipating plate device, N first heat-conducting devices, N
diode light-emitting apparatuses, a hollow barrel, and a transparent shield. N is a natural number.
The heat-dissipating plate device includes a first surface and a second surface opposite to the first surface. A number of heat-dissipating fins extend 2a from the second surface. Each of the first heat-conducting devices is divided into a first part and a second part extending from the first part. The second part includes a flat end. Each of the diode light-emitting apparatuses corresponds to one of the N
first heat-conducting devices, and is flatly mounted on the flat end of the corresponding first heat-conducting device for converting electrical energy into light.
The heat generated by each of the diode light-emitting apparatuses in operation is conducted from the flat end through the second part and the first part of the corresponding first heat-conducting device to the heat-dissipating plate device and the heat-dissipating fins, so as to be dissipated by the heat-dissipating plate device and the heat-dissipating fins.

The heat-isolating plate device thereon includes N first through holes, and each of the first through holes corresponds to one of the diode light-illuminating apparatuses. The heat-isolating plate device is disposed in the hollow barrel to separate the interior space into a first room and a second room, such that each of the diode light-emitting apparatuses passes through the corresponding first through hole to be disposed in the second room.

Besides, according to the preferred embodiment, the LED illuminating equipment further includes a heat-isolating ring. The hollow barrel is engaged to the circumference of the heat-dissipating plate device via the heat-isolating ring, so as to
3 isolate the heat conducted to the heat-dissipating plate device to prevent the heat from being conducted to the hollow barrel. By doing so, the LED illuminating equipment will not have a non-uniform heat-distribution, and further the heat-dissipating efficiency can be raised. In addition, the heat-isolating ring can prevent liquid from permeating into the LED illuminating equipment, so the LED illuminating equipment is equipped with water-proof.
Therefore, according to the embodiment of the invention, the LED illuminating equipment has a better heat-dissipating efficiency, and liquid can be prevented from permeating into the LED illuminating equipment. Accordingly, the LED illuminating equipment of the invention is suitable for a street lighting apparatus.

4B. Or, the flat end 126 is formed by bending and flattening the end of the second part 124, as shown in FIG. 4C.
It should be remarked that each of the diode light-emitting apparatuses 13 corresponds to one of the N first heat-conducting devices 12. Each of the diode light-emitting apparatuses 13 is flatly mounted on the flat end 126 of the corresponding first heat-conducting device 12, and is used for converting electrical energy into light.
Accordingly, the heat generated by each of the diode light-emitting apparatuses 13 in operation is conducted from the flat end 126 of the corresponding first heat-conducting device 12 via the second part 124 and the first part 122.
Therefore, the heat is conducted to and dissipated by the heat-dissipating plate device 11 and the heat-dissipating fins 16.

Each of the diode light-emitting apparatuses 13 is flatly mounted on the flat end 126 of the corresponding first heat-conducting device 12, and is used for converting electrical energy into light.
Accordingly, the heat generated by each of the diode light-emitting apparatuses 13 in operation is conducted from the flat end 126 of the corresponding first heat-conducting device 12 via the second part 124 and the first part 122.
Therefore, the heat is conducted to and dissipated by the heat-dissipating plate device 11 and the heat-dissipating fins 16.
The hollow barrel 14 is engaged to circumference of the heat-dissipating plate device 11, so as to form an interior space 17 for accommodating the first heat-conducting devices 12 and the diode light-emitting apparatuses 13.
