## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is related with the module structure of LED lights and radiator, especially for the light module comprises with aluminum base, radiators, LED lights and the lamp mask. The light module comprises LED lights and the radiator which can be fabricated and dismantled rapidly through the screws.
2. Description of the Related Art
“Assembled structure of large-sized LED lamps”, the prior invention, which is granted by U.S. Pat. No. 7,338,186 as shown in FIGS. 1 and 2, the prior invention comprises a cover, a radiator, an aluminum base, lights and a lamp mask. Several heat-dissipating holes are set on four sides of the cover. The radiator is set on top of the aluminum base. Fix the cover and the aluminum base, and cover the radiator in the cover. The lights are set at the bottom of the aluminum base and then fixed to the lamp mask. The lights comprise the LED lights and the circuit board.
However, the “assembled structure of large-sized LED lamps” mentioned above has the following shortcomings:

    
    
        1. There are no penetrating holes setting on the aluminum base which can not allow the heat produced by the radiator and the LED lights scattered. Moreover, when things or water get into the cover, it can not be drained.
        2. There are no penetrating holes on the aluminum base, therefore, the heat-dissipating holes can be only set on sides of the cover. Otherwise, it will cause lots of things getting into the cover and can not be obviated.
        3. When changing or fixing the radiator, the aluminum base and the cover need to be dismantled. The structure of the prior invention is more complicated, and the design of the radiator and the LED lights is inconvenient for being fabricated and dismantled separately.
    
    


SUMMARY
The present invention relates to a module structure of the LED lights and radiator which comprises a shell and a light module. A bottom cover set around with many heat-dissipating holes and a container which forms a containing space. Several penetrating holes and fitting holes are set at the bottom of the bottom cover. Several screw holes are set around the fitting holes. A light module comprises an aluminum base, radiator which is on the aluminum base, LED lights and a lamp mask. The screw holes on the surface of the aluminum base correspond to the screw holes on the bottom cover. A circuit board is set under the bottom of the aluminum base. The radiator is fixed on top of the aluminum base. LED lights are set on the circuit board which is at the bottom of the aluminum base. A lamp mask fixes the circuit board through screws.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 3 through 8, the module structure of the LED lights and radiator comprises a shell (10) and a light module (20). A shell (10) comprises a top board (11) and a bottom cover (12). Several heat-dissipating holes (111) which allow the air in are on the top board (11). A bottom cover (12) is set around with many heat-dissipating holes (124) and therein is a container (125) which forms a containing space. Several penetrating holes (121) and fitting holes (122) are set at the bottom of the bottom cover (12). Several screw holes (123) are set around the fitting holes (122).
As shown in FIGS. 3 and 3-1, the light module (20) comprises a aluminum base (21), a radiator (23), LED lights (24) and a lamp mask (25). The area of the aluminum base (21) is bigger than the area of the fitting holes (122) setting at the bottom of the bottom cover (12). The screw holes (211) correspond to the screw holes (123) on the bottom cover (12). A circuit board (22) is set at the bottom. The radiator (23) is set on top of the aluminum base (21). The LED lights (24) are set on the circuit board (22) which is at the bottom of the aluminum base (21). A lamp mask (25) on the circuit board (22) is fixed through screws to cover the LED lights (24) in the lamp mask (25). As shown in FIG. 4, the radiator (23) of the light module (20) is on the top, the LED lights (24) and the lamp mask (25) are below; fix the screw holes (123) and the screw holes (211) correspondingly with screws, therefore, the light module (20) and the bottom cover (12) are connected. As shown in FIGS. 5 and 6, the area of the aluminum base (21) is bigger than the fitting holes (122), therefore, the aluminum base (21) can not move through the fitting hole (122), instead, it leans against the bottom of the bottom cover (12). The radiator (23) is set in the container (125) of the bottom cover (12) through the fitting hole (122).
As shown in FIG. 7, this is the first example of the present invention. Replace the shell (10) with the retaining seat (30), and set the retaining holes (31) on the retaining seat (30). Set the light modules (20) in the retaining holes (31). Without the shell (10), the whole structure is better for heat-dissipating and water-draining, and it prolongs the using terms of the LED lights (24). As shown in FIG. 8, the penetrating holes (32) can be set around the retaining holes (31) of the retaining seat (30) to improve the effect of the water-draining.
As shown in FIGS. 9 and 10, the light modules (81) comprise more than two individual light modules (20), which are shown in FIG. 7. More than two radiators (23) can be set on top of the aluminum base (21), and more than two circuit boards (22) and LED lights (24) can be set at the bottom covered by a lamp mask (25).
The present invention mentioned above has the advantages as following:

    
    
        1. Several penetrating holes (32) are set on the bottom board, therefore, it speeds up the heat-dissipating of the light module (20) through the convection between the top and the bottom boards. Also, it prolongs the using terms of the LED lights (24). When things or water get into the shell (10), it can be easily drained away through the penetrating holes (32).
        2. Because several penetrating holes (32) are on the bottom board, the heat-dissipating holes (111) of the top board (11) may set not only on the side, but also on the top. It can speed up the heat-dissipating effect between two boards.
        3. The light module (20) of the present invention is a single light module (20). The single light module (20) comprises an aluminum base (21), a radiator (23), LED lights (24) and a lamp mask (25). The light module (20) can be easily fabricated in the fitting hole (122) on the shell (10) or be easily dismantled. An individual light module (20) can be changed when fixing instead of taking down whole structure of the module and then installing parts of the module back. The present invention will save more time and reduce the difficulty on fixing than the prior invention.
