Definitions

  • the present invention relates to a retention mechanism for the shell of a light- emitting diode (LED) light bulb.
  • LED light- emitting diode
  • LEDs are highly efficient light sources, and seem likely to eventually replace almost all other light sources.
  • LED light bulbs that have prevented their wide-spread adoption until now.
  • One of the most important of these problems is that it is difficult to make an LED light bulb that has the same shape as the incandescent bulb it is intended to replace.
  • LED light bulbs In the case of an LED light bulb, however, this process is more problematic.
  • the heatsink flares out, and thus is wider than the screw base, and thus must be inserted prior to the shell being assembled.
  • the LEDs are semiconductors, and typically have a maximum temperature of only 150°C. They cannot withstand the very high temperatures that glass needs in order to be shaped.
  • LED light bulbs typically use plastic instead of glass, but the molding temperatures of the plastics typically used is still higher than the maximum withstand temperature of the LEDs. LED light bulbs thus face the 'ship in the bottle' problem: the heatsink must be inside the shell, but it doesn't fit through the opening at the screw base, and the shell can't be formed around the heatsink because the LEDs attached to it can't withstand the necessary temperatures.
  • the present disclosure is directed to an LED light bulb, with a two-piece shell that has the two pieces secured together with snap clips.
  • the shell is made of plastic and the snap clips are made of the same material as the shell pieces.
  • the snap clips are molded into the plastic shell pieces, so that no extra steps are required to manufacture or attach them, while requiring only a small amount of extra shell material.
  • the heatsink and any other components internal to the shell are assembled in place, and then the two pieces of the shell are placed on either side of them and snapped together. Since no gluing or other chemical steps are necessary, the assembly cost is thus minimal.
  • the snap clips may be composed of two different pieces, the insertion piece and the retention piece.
  • each shell half has one insertion piece and one retention piece, both in the same plane. This permits the two shell halves to be identical, requiring only one mold for the shell halves.
  • FIG. 1 is a cross-sectional drawing of an LED light bulb showing the internal heatsink and two shell halves with molded-in snap clips, according to one or more embodiments shown or described herein.
  • FIG. 1 is a cross-sectional drawing of an LED light bulb 100 showing the internal heatsink 110 and two shell halves 120 each with two halves of molded-in snap clips 130.
  • each shell half 120 has both an insertion piece 140 and a retention piece 150 of the molded-in snap clips 130.
  • the insertion pieces 140 and the retention pieces 150 are all in the same plane.
  • the flange 141 of the insertion piece 140 fits into the clasp 151 of the retention piece 150 when pressure is applied, and then cannot be easily be backed out.
  • the heatsink 110 flares out as it comes away from the screw base 110.
  • the two shell halves 120 are placed on either side of the heatsink 110.
  • the two shell halves 120 are then pushed together, engaging the two pairs of snap clips 130. Once the snap clips 130 are engaged, the shell halves 120 can no longer be easily separated, completing assembly of the shell.

Abstract

L'invention porte sur un mécanisme de retenue pour l'enveloppe d'une ampoule électrique à diode électroluminescente (DEL) qui est constituée par deux moitiés de l'enveloppe, au moins une attache, dont une moitié se trouve sur l'une parmi les moitiés d'enveloppe et dont l'autre moitié se trouve sur l'autre moitié d'enveloppe, et la moitié de la au moins une attache se verrouillant mutuellement sur l'autre moitié de la au moins une attache.
