Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to the technical field of illumination lamp modules, and more particularly to a waterproof multifunctional lamp that is combined with an installation plate and can be used in various places by screwing, hanging, magnetic attraction or tying methods. 
     2. Description of the Related Art 
     In recent years, light emitting diode (LED) has the advantages of low voltage, low power consumption and long life over conventional light sources, and thus various illumination lamp modules applying LEDs are introduced into the market. Since the LED has a significant advantage in power saving, therefore it is used extensively in the field of illumination, and its practicality becomes very important. 
     At present, the common lamp modules adopting the LED as an illumination source include road lamps, indoor illumination lamp modules, table lamps or even flashlights. LED emits light by using a power driver chip (also known as LED chip) with regulated voltage and current, so that there are issues of increasing the temperature and generating heat during the light emission. In particular, some high-power LED chips generate high heat, so that the chip of the illumination lamp module or electric power control board will overheat, and the life of the lamp will be shortened significantly. Therefore, solving heat dissipation issue is the first priority in most of the LED lamp modules. In addition, various types of LED lamp modules adopt different fixing methods or different designs of fixing bases according to their application. Traditional fixing base is generally used in the illumination lamp module, so that the conventional lamp module can be used at a fixed point. However, the illumination area of the conventional illumination lamp is very limited; thus, the conventional illumination lamp module has a narrow scope of applicability and requires improvements. 
     In view of the aforementioned problems of the conventional illumination lamp, the inventor of the present invention designed and developed a waterproof multifunctional lamp that can be fixed by screwing, magnetic attraction, hanging or typing methods, and the multifunctional lamp has a design with an LED lamp panel and an electric power control board integrated or detached with respect to each other, so as to improve the practical application of the lamp.
