Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to lamps and more particularly to a modularized lamp mounted in a reflector device having advantages of being ease of mass production and being waterproof and airtight, and method of manufacturing same.  
         [0003]     2. Description of Related Art  
         [0004]     A prior reflector belt (or reflector device) comprises a plurality of illuminators electrically coupled together by electric wires, a switch, a power supply (or batteries), a flash controller all coupled to the illuminators, and a reflective strip (or waterproof belt) for enclosing the above components. The reflector belt is typically stitched to a clothes or the like. Such design has been disclosed in Taiwanese Patent Published Nos. 355,642 and 383,121. However, it is impossible of manufacturing the prior art in a modularized, mass production since the coupling of illuminators, wires, and other electrical components and the stitching process are tedious and time consuming. Hence, the prior art finds it hard of putting into practice in industry. Moreover, in fact spacing between any two illuminators has to be adjusted in order to adapt to the article (e.g., shoulder belt or waist belt of a clothes) that the prior art is attached to. Thus, the manufacturer has to prepare many sets of illuminators having different spacings and belts of different lengths for fulfilling different needs of customers. This inevitably will increase the manufacturing cost and lower the production. Also, an additional waterproof treatment has to be done on the prior reflector belt. This further complicates the manufacturing process. To the worse one such reflector belt having a poor waterproof or airtight capability may cause danger (e.g., spark or explosion caused by exposing wires, flash controller, and illuminators to air having gas or other inflammable articles) when it is used in an environment requiring a highly safe operating standard. Hence, a need for improvement exists.

Next, insert the rivets  141  and  142  through the apertures  221  and  222  of a cover plate  22  to project from the cover plate  22  which is in turn placed on the support  13 A for covering. Next, conductive bars  165  and  166  are inserted in the slits  163  and  164  and the hollow shanks of the rivets  141  and  142  respectively. Next, fasten the cover plate  22  and the support  13 A together by means of a high-frequency or ultrasonic welder. As an end, a lamp unit  1  having exposed rivets  141  and  142  is formed (see  FIG. 31 ).  
         [0077]     Referring to FIGS.  32  to  34 , forming process of the lamp unit is illustrated. The LED lamp  12  is a COB based LED (as shown), SMD based LED, or lead frame based LED. The LED lamp  12  and the rivets  141  and  142  are mounted in the base  11 . Next, the base  11  is placed on a die A of an injection molding machine. An encapsulation  13 B is then formed after performing the manufacturing steps shown in  FIGS. 33 and 34 . FIGS.  35  to  37  show three different shapes of lamp units  1 A formed in a manufacturing process the same as that shown in FIGS.  32  to  34  in which each lamp unit  1 A has exposed rivets  141  and  142 .  
         [0078]     Referring to  FIGS. 38 and 39 , two waterproof rings  134  are integrally formed with a seat assembly  13 . The rivets  141  and  142  are then inserted through the lamp unit  1 , the waterproof rings  134 , and the belt unit  2  prior to being flattened to compress the waterproof rings  134 . As such, a portion of waterproof treatment is achieved in the joining portion of the rivets  141  and  142 , the belt unit  2 , and the lamp unit  1 . Finally, a waterproof pad  31  is adhered on the belt unit  2  to cover the flattened portions of the rivets  141  and  142  thereon. As an end, a complete waterproof treatment is achieved.  
         [0079]     Referring to  FIGS. 40 and 41 , two waterproof rings  134 A are placed on apertures of the seat assembly  13 . The rivets  141  and  142  are then inserted through the lamp unit  1  (i.e., the apertures of the seat assembly  13 ), the waterproof rings  134 A, and the belt unit  2  prior to being flattened to compress the waterproof rings  134 A. As such, a portion of waterproof treatment is achieved in the joining portion of the rivets  141  and  142 , the belt unit  2 , and the lamp unit  1  together. Finally, a waterproof pad  31  is adhered on the belt unit  2  to cover the flattened portions of the rivets  141  and  142  thereon. As an end, a complete waterproof treatment is achieved.  
         [0080]     Referring to  FIGS. 42 and 43 , two waterproof rings  134  are integrally formed with a seat assembly  13 . Also, two second waterproof rings  134 B are in the waterproof rings  134 . The rivets  141  and  142  are then inserted through the lamp unit  1 , the waterproof rings  134 , the second waterproof rings  134 B, and the belt unit  2  prior to being flattened to compress the waterproof rings  134  and second waterproof rings  134 B. As such, a portion of waterproof treatment is achieved in the joining portion of the rivets  141  and  142 , the belt unit  2 , and the lamp unit  1 . Finally, a waterproof pad  31  is adhered on the belt unit  2  to cover the flattened portions of the rivets  141  and  142  thereon. As an end, a complete waterproof treatment is achieved.  
         [0081]     In brief, a number of configurations of the invention are made possible. For example, after mounting the LED lamp  12  and the rivets  141  and  142  in the base  11 , place one or more bases  11  on a die of injection molding machine. Finally, one or more encapsulations  13 B (i.e., lamp units  1 ) are formed by punching. Alternatively, after mounting the LED lamp  12  and the rivets  141  and  142  in the support  13 A, form an encapsulation  13 B on the support  13 A or place a cover plate  17 ,  18 , or  19  on the support  13 A prior to encapsulation. As to the rivets  141  and  142 , they can be projected from the support  13 A, the base  11 , the encapsulation  13 B, or the cover plate  17 ,  18 , or  19 . As to the encapsulation, it can be one of bond injection, bond injection to adhere to the cover plate  17 ,  18 , or  19 , plate based heating for encapsulation by means of a high-frequency or ultrasonic welder, and injection molding.
