Title: Structure of led light

Description:
TECHNICAL FIELD OF INVENTION 
     The present invention generally relates to a structure of an illuminating light in which a light source and a heat dissipation mechanism are separated, and more particularly to an improved structure of an LED light that shows a high efficiency of light utilization and a high efficiency of heat dissipation. 
     DESCRIPTION OF THE PRIOR ART 
     The discovery and use of light imposes a tremendous influence on human history of civilization. From early days when a burning fire was used for lighting to the state-of-the-art technology of LED, all are provided for lighting and to improve living quality of human beings. 
     The contemporary lighting technology, either LED or other different types of lighting components, electrical power from an electric main must be converted into a standard that is usable for the lighting components. During the operation, the drive module that carries out conversion of electrical power and the lighting elements both generate waste heat. Further, in the current designs of lights, the drive module and the lighting component are often arranged adjacent to each other. Such an arrangement generally leads to mutual influence of the heats generated thereby, making the overall temperature excessively increased and dissipation of heat difficult. When put in operation in such a high temperature in an extended period of time, the lights may get damaged. 
     Further, light utilization efficiency is also an important topic. Most of the conventional lighting devices are arranged to provide a heat dissipating coating on a surface thereof. This arrangement is made to improve the issue of heat dissipation. However, this arrangement causes another problem, which is a problem associated with light utilization efficiency. Thus, the conventional lighting devices cannot simultaneously achieve the purposes of optimizing light utilization efficiency and optimizing the result of heat dissipation. 
     Thus, it is a challenge of the present inventor and the manufacturers of the industry to overcome the above discussed problems. 
     SUMMARY OF THE INVENTION 
     In view of the above drawbacks, the present invention aims to provide an improved structure of an LED light that features high light utilization efficiency and high heat dissipation efficiency. 
     The primary object of the present invention is to arrange a light source module and a heat dissipation module to be spaced from each other with contact being made therebetween at a single end. As such, components that generate heat internally are kept from each other by a predetermined distance to provide an excellent heat dissipation environment. Further, with a collaborative arrangement of a light reflector and a light emission element, the utilization of light is optimized. With such a technique, the problems of the conventional lighting device that the generated waste heats may affect each other and thus result in a poor heat dissipation environment and the efficiency of light utilization is poor can be overcome to achieve the practical advantages of high efficiency of light utilization and high efficiency of heat dissipation. 
     To achieve the above object, the present invention comprises a light source module and a heat dissipation module. The light source module comprises a plurality of compartments formed therein. Each of the compartments receives a light reflector and a light emission element mounted therein. The compartments are provided, at an end distant from the light emission elements, with a seat. Each of the compartments is provided with a cover. Further, the heat dissipation module has an outer wall that forms a heat dissipation fin section. The heat dissipation module receives therein a drive module electrically connected to the light emission elements. The seat of the light source module is coupled to the heat dissipation module. 
     With such an arrangement, when the drive module is supplied with electrical power and set into operation, the light emission element immediately operates and gives off light. The heat emitting from the drive module is primarily dissipated through the heat dissipation fin section to avoid accumulation of the heat and thus maintaining an excellent condition of the operation environment. Most of the light generated by the light emission element is projected out in a manner of normal incidence and remaining light scattered in other directions is collected and outward projected again with the assistance of the configuration of the compartments and the arrangement of the light reflectors. Thus, the light can be utilized with the most efficient manner to achieve the best utilization efficiency to thereby realize the practical advantages of high efficiency of light utilization and high efficiency of heat dissipation. 
     The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims. 
     Referring to  FIGS. 1 ,  2 ,  3 ,  4 ,  4 A,  5 , and  6 , which are respectively a perspective view, an exploded view, another exploded view, a schematic view, and a partial schematic view of a preferred embodiment of the present invention and a schematic view illustrating light illumination of the preferred embodiment of the present invention and a schematic view illustrating heat dissipation of the preferred embodiment of the present invention, these drawings clearly show that the present invention comprises the following constituent components: 
     A light source module  10  comprises a plurality of compartments  11  formed therein. Each of the compartments  11  receives a light reflector  12  and a light emission element  13  mounted therein. The compartments  11  are provided, at an end distant from the light emission elements  13 , with a seat  14 . Each of the compartments  11  is provided with a cover  15 . 
     A heat dissipation module  20  is coupled to the seat  14 . The heat dissipation module  20  has an outer wall that forms a heat dissipation fin section  21 . The heat dissipation module  20  receives therein a drive module  22  electrically connected to the light emission elements  13 . 
     The light source module  10  comprises a bore  16  formed therein. The bore  16  is provided with a corresponding lid  17  thereon. The light reflectors  12  have a shape corresponding and mating the shape of the compartments  11 . Each of the light reflectors  12  comprises an opening  121  formed therein and the light emission element  13  is mounted in the opening  121 . The compartments  11  form a plurality of retention tenons  111  and the openings  121  comprise retention mortises  122  mating the retention tenons  111 . 
     The covers  15  are made of a light-transmitting material. The light emission elements  13  comprise a light-emitting diode. The heat dissipation module  20  comprises an electrical conduction section  23 . The electrical conduction section  23  is electrically connected to the drive module  22  and the electrical conduction section  23  is set at the end of the heat dissipation module that is distant from the seat  14 . 
     Based on the above-described structure, the following description will be given to help understanding of the technical features of the present invention. Referring to  FIGS. 1-4 , a description of the light structure and the assembling structure of the present invention will be made, which is generally composed of two major modules, namely the light source module  10  and the heat dissipation module  20 . In the instant embodiment, the light source module  10  comprises three compartments  11 . To mount the light reflectors  12  to the compartments  11 , the retention tenons  111  are set to mate the retention mortises  122  and the covers  15  are fit into the compartments  11 , whereby the assembling efficient and convenient and simplification of the manufacturing flow can be achieved. Referring to  FIGS. 5 and 6 , to use, the electrical conduction section  23  is coupled to a corresponding socket to establish electrical connection therebetween. During the supply of electrical power, the light emission elements  13  that are included in the light source module  10  and the drive module  22  that is mounted in the heat dissipation module  20  are kept from each other by a predetermined distance so that the heats generated thereby do not affect each other. Further, the heat of the drive module  22  is efficiently conducted out through the heat dissipation fin section  21  so that the heat dissipation module  20 , in entirety, may maintain an excellent heat dissipation environment. Further, heat is also conducted out through the bore  16  to provide chimney effect based heat dissipation. As such, the whole device can be maintained in an excellent operation temperature, suppressing light attenuation and reduction of lifespan caused by over-heating and also achieving optimization of heat dissipation. As to illumination, since the light emission elements  13  are mounted in the openings  121  of the light reflectors  12 , when the light emission elements  13  give off light, most of the light transmits through the cover  15  in a manner of normal incidence and the remaining scattered light is incident onto the light reflectors  12  of high reflectivity and reflected again thereby to transmit through the cover  15 . With the arrangement of the light reflector  12 , an optimum result of use can be achieved for generation and utilization of light and the device, as a whole, provides extraordinary performance to achieve practical advantages of high light utilization efficiency and high heat dissipation efficiency. 
     Thus, the present invention provides an improved structure of an LED light that provides the following key techniques for improving the known technique: 
     (1) The light source module  10  and the heat dissipation module  20  are kept from each other by a predetermined distance so that the heat sources do not affect each other and thus, an excellent operation environment can be maintained to achieve an advantage of high heat dissipation efficiency. 
     (2) The light emission elements  13  are used in combination with the light reflectors  12  to allow scattered light to be used again so as to realize the optimum use of the light and thus achieving an advantage of high efficiency of light utilization. Further, the design of the cover  15  helps control the projection direction of the light. 
     It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
