Therefore, it only requires an external force to engage the hook portion 736 with the clasping member 104. More specifically, to assemble the electronic module 700, 700' to the module base 400, a repairman or a user only needs to make the second plate 740 of the fastening implement 720 be in alignment with and then assembled to the first plate 410 of the module base 400, and then the elastic locking element 730 can engage with the clasping member 104.

- It is an object of the present invention to provide a light emitting diode (LED) lamp structure, in which assembling, disassembling and replacing can be achieved without any tools, and meanwhile, the entrance of moisture is also prevented, so that a life span of an electronic device is prolonged.
- Accordingly, the present invention provides a LED lamp structure comprising a housing body, a LED lamp module, and an electronic module. The housing body includes a lamp base, a module base, a connecting ring connecting the lamp base, and at least one clasping member connecting the module base. The LED lamp module connects the connecting ring and is disposed on the lamp base. The electronic module connects the clasping member and is disposed on the module base.
- The present invention also has the following effects: after the LED lamp module is in alignment with the lamp base, it only requires inserting the LED lamp module into the lamp base and rotating the LED lamp module by a small angle, and then the assembly can be achieved fast and stably. Therefore, even an ordinary consumer can finish assembling or disassembling in a simple and efficient way.

LED lamp module 500 of the present embodiment will be described hereinafter with reference toFig. 2 . Preferably, the connectingring 300 is ring-shaped, consists of plastic or metal, and is positioned and fixed on thehousing body 102 by screws (not illustrated). Each of thenotches 320 and thepress portions 310 is equidistant from one another on the connectingring 300. In another preferable embodiment, the connectingring 300 can be integrally formed with thehousing body 102. According to the present embodiment, each of thenotches 320 and thepress portions 310 divides the connectingring 300 into 6 parts, and each part substantially has a central angle of 60 degrees. However, in different embodiments, each of thenotches 320 and thepress portions 310 divides the connectingring 300 into 4 parts, and each part substantially has a central angle of 90 degrees. - It should be noted that, the connecting
ring 300 of the present embodiment consists of plastic or metal and is fixed to thelamp base 200 by screws or other components.

The joiningring 520 is hollow and has some integrally-formedfastening portions 524 to engage correspondingrecesses 517, so as to position and fix the joiningring 520 on thelight source 510. The joiningring 520 has somehook portions 528 on the other lateral edge opposite to thefastening portions 524. Eachhook portion 528 hooks an inner edge of an open hole of therotatable ring 530, so as to restrict a movement of therotatable ring 530 along an axial direction. Theelastic positioning portion 522 elastically reciprocate on a circular-arc-shaped surface of the joiningring 520, which allows visual inspection of therotatable ring 530 to determine whether it is rotated to a locked state. - Referring to
Fig. 3 andFig. 5 , an outer surface of therotatable ring 530 further forms a plurality ofopenings 534, and theelastic positioning portion 522 is disposed corresponding to theopening 534. When therotatable ring 530 rotates, thehook portion 528 restricts the movement ofrotatable ring 530 along the axial direction, but does not affect the rotation of therotatable ring 530. Furthermore, when therotatable ring 530 rotates, theelastic positioning portion 522 moves from one of theopenings 534 to engage an adjacent or corresponding one of theopenings 534. The location of eachopening 534 is designed according to a rotation distance of the guidinggroove 312 on thepress portion 310, which is for example 90 degrees or 60 degrees and varies according to requirements or designs. - Referring to
Figs. 6 to 9 , detailed descriptions are provided hereinafter to explain how theLED lamp module 500 is assembled to thelamp base 200. To assemble theLED lamp module 500, at first a repairman makes theLED lamp module 500 be in alignment with thelamp base 200. In other words, eachconductive terminal 512 of thelight source 510 is inserted into acorresponding slot 210 of thelamp base 200 in order to make an electrical connection, as shown inFig. 9 . At this point, the slidingblock 532 of therotatable ring 530 enters into a corresponding one of thenotches 320. When therotatable ring 530 rotates, the slidingblock 532 slides along the guidinggroove 312 and rotates by an angle B to make theLED lamp module 500 positioned on thelamp base 200 at last. - According to the embodiment shown in
Figs. 7 and8 , an end surface of the guidinggroove 312 further has a protrudingportion 314 for engagement with the slidingblock 532. The angle B hereinbefore is preferably 60 degrees. In other words, a central angle of each press portion 310 (i.e. the guiding groove 312) on the connectingring 300 is around 60 degrees. However, in different embodiments, the angle B can be around 90 degrees, namely a central angle of eachpress portion 310 on the connectingring 300 is around 90 degrees. Since the angle B is very small, even an ordinary user can assemble theLED lamp module 500 to thelamp base 200 fast and efficiently without any tools. - Referring to
Figs. 10 and11 , to disassemble theLED lamp module 500 from thelamp base 200, the repairman rotates therotatable ring 530 at first, to make the slidingblock 532 of therotatable ring 530 detached from the protrudingportion 314 of the guidinggroove 312, until the slidingblock 532 slides to thenotch 320 of the connecting ring 300 (i.e. rotating by the angle B). When the slidingblock 532 of therotatable ring 530 gradually slides to the highest of thenotch 320, owing to the design of the inclined angle A of thenotch 320, theLED lamp module 500 is gradually detached from thelamp base 200 in a vertical direction. Referring toFig. 11 , theconductive terminal 512 of theLED lamp module 500 is removed by the connectingring 300 from thelamp base 200 of thehousing body 102 in a vertical direction. Finally, theconductive terminal 512 of theLED lamp module 500 is entirely detached from theslot 210 of thelamp base 200 to complete the disassembly operation. - Therefore, to disassemble the
LED lamp module 500, the angle B by which therotatable ring 530 rotates to disassemble theLED lamp module 500 is very small. Thus, the repairman can disassemble theLED lamp module 500 from thelamp base 200 fast and efficiently without any tools, thereby further preventing damaging theconductive terminals 512 of theLED lamp module 500. -
Fig. 12 is a partially enlarged view of a second embodiment of the present invention, namely a partially enlarged view of between theelectronic module 700, 700'and themodule base 400.

Thehook portion 736 is disposed corresponding to theclasping portion 104 and provided for engaging the same. - A length from the
press portion 732 to the pivotingportion 734 is greater than a length from thehook portion 736 to the pivotingportion 734. Therefore, when pressing thepress portion 732, thepress portion 732 rotates around the pivotingportion 734, and thus thehook portion 736 is moved toward a direction away from thesecond plate 740. Consequently, thehook portion 736 is detached from the claspingmember 104, so as to make theelectronic module module base 400. Similarly, when assembling theelectronic module module base 400, the operation is alike. - It should be noted that, the appearances, levels, sizes, and kinds of the power-and-
signal socket 430 and the power-and-signal plug 780 vary from country to country, and a repetitive description thereof is omitted herein. - Referring to
