Definitions

  • the present invention relates generally to an LED fitting, and more particularly to an innovative one which can be assembled with LED unit.
  • LED has been widely applied to many light-emitting products such as: common lamps, projectors, traffic lights, traffic marking panels, advertisement lamp boxes, decorative lights and car lights, in lieu of conventional luminous bodies.
  • LEDs must be arranged at interval and also linked by electrical wire or circuit board to show the light-emitting effect; however, every linking position is vulnerable to water ingress or moisture in the operating environment of the products; in such case, the electrical wire or circuit board of LED is possibly burnt due to short circuit; hence, water-proofing packaging of electric structure is a crucial technology issue when the operational safety and service life of LED products are considered.
  • the water-proofing conventional LED products are structurally designed in such a way that the electrical wire or circuit board is poured and covered with water-proof adhesive; such water-proofing structure can meet the water-proofing requirements, but a huge amount of water-proof adhesive has to be utilized, leading to higher fabrication cost and longer fabrication time against the customers; moreover, such a water-proofing structure brings about time-consuming and difficult replacement in the event of LED damage.
  • the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
  • the enhanced efficacy of the present invention is as follows:
  • FIGS. 1 ⁇ 4 depict preferred embodiments of an LED water-proofing diffuser of the present invention embedded into shell plate, which, however, are provided for only explanatory objective for patent claims.
  • Said LED water-proofing diffuser A comprising:
  • the LED diffusing portion 20 is protruded from the center of the end wall 11 of the LED baseplate retaining shell 10 (shown in FIGS. 1 ⁇ 8 ).
  • the LED water-proofing diffuser A is assembled externally onto an LED unit 40, which comprises at least an LED module 41, an LED substrate 42 and electrical wire 43; the LED baseplate retaining shell 10 of LED water-proofing diffuser A is used for accommodating the LED substrate 42 of LED unit 40, and the LED diffusing portion 20 is used for accommodating the LED module 41 of LED unit 40; moreover, waterproof agent 50 is poured into the LED baseplate retaining shell 10 to seal the LED substrate 42.
  • said LED unit 40 permits to protect the exposed LED module 41 against moisture by assembly of the LED water-proofing diffuser A; besides, the LED substrate 42 and the electrical connecting position of LED substrate 42 and electrical wire 43 can also be protected against moisture by accommodation of the LED baseplate retaining shell 10 and sealing of waterproof agent 50.
  • a protruding rib flange 14 is formed internally onto the end wall 11 of the LED baseplate retaining shell 10; the protruding rib flange 14 can limit the assembly depth of the LED substrate 42; meanwhile, a spacing can be formed between the LED substrate 42 and end wall 11 of the LED baseplate retaining shell 10, thereby achieving appropriate heat-sink cooling effect to extend the service life of LED unit 40.
  • LED water-proofing diffuser A is operated as follows:
  • said LED water-proofing diffuser A is applied to an advertisement 70;
  • the advertisement 70 comprises of a main body 71, an LED unit 40 set on the advertisement surface 72 of the main body 71, and an LED water-proofing diffuser A assembled externally on to said LED unit 40; of which the advertisement surface 72 of the main body 71 is provided with a hole 73 for embedding of the LED water-proofing diffuser A and positioning of the LED unit 40.
  • said LED water-proofing diffuser A is applied to a platy ornament 80;
  • the platy ornament 80 comprises of a main body 81, an LED unit 40 set on the platy surface 82 of the main body 81, and an LED water-proofing diffuser A assembled externally on to said LED unit 40; of which the platy surface 82 of the main body 81 is provided with a hole 83 for embedding of the LED water-proofing diffuser A and positioning of the LED unit 40.
  • the embedded positioning portion 30 is formed externally onto the circumferential flange 12 of the LED baseplate retaining shell 10, and composed of a plurality of oblique elastic sheets 33 with latching portion 32; so the elastic sheets 33 can be embedded securely into the hole 06 of existing shell plate 05.
  • the embedded locating portion 30 consists of a snapping flange 34 and a stopping flange 35; of which the stopping flange 35 is abutted onto the inner surface of the shell plate 05 for limitation (shown in FIG. 12 ); the snapping flange 34 is snapped into one end of the hole 06 of the shell plate 05 (shown in FIG. 12 ), or embedded securely into hole 06 of the shell plate 05.
  • the embedded locating portion 30 is provided with a plurality of stepped teeth 36; in this preferred embodiment, the embedded locating portion 30 can be adapted to be assembled robustly in response to the size of hole 06 of the shell plate 05.
  • the embedded locating portion 30, including a snapping flange 34 and a stopping flange 35, is arranged externally onto the peripheral wall 22 of the diffusing portion 20.
  • the embedded locating portion 30 is provided with a frictional positioning flange, which is composed of refined lugs, raised teeth or ribs protruded laterally onto the light bulge 23 (or diffusing portion 20), allowing to snap into the hole of the shell plate through frictional engagement.
  • the present invention is also characterized by that, the diffusing portion 20 consists of a light bulge 23 extended from the end wall 21; and the embedded locating portion 30 is located correspondingly to the light bulge 23; the end surface 231 of the light bulge 23 is of either a flat surface (shown in FIG. 9 ), a curved surface (shown in FIG. 14 ), a tapered surface or a toothed surface; moreover, the light bulge 23 can be designed into either a solid cylinder or a hollow tube.
  • the radial profile of the peripheral wall 22 of the diffusing portion 20 and the light bulge 23 is of either a round, elliptical, rectangular, oblong or polygonal shape; referring to FIG. 9 , the radial profile of the diffusing portion 20 and the light bulge 23 is of a round shape; referring also to FIG. 17 , the radial profile of the diffusing portion 20B and the light bulge 23B is of a rectangular shape; referring also to FIG. 18 , the radial profile of the diffusing portion 20C and light bulge 23C is of an oblong shape.
  • the embedded locating portion 30 also comprises a liner 37, which is made of solid or flexible materials in a circular or C-shaped pattern; with the arrangement of the liner 37, compact and robust assembly is made possible in response to the shell plate 05 of different thickness; referring to FIG. 19 , the gap between the snapping flange 34 and stopping flange 35 of embedded locating portion 30 is bigger than the thickness of the shell plate 05; so, the liner 37 can be filled reliably between the stopping flange 32 and shell plate 05; said liner 37 is also suitable to the embedded locating portion disclosed in FIGS. 13 and 16 .
