RETENTION MECHANISM FOR LED LIGHT BULB INTERNAL HEATSINK

摘要

The present disclosure is directed to an LED light bulb, with an interior heatsink that is held in place by a protrusion or protrusions on the inside of the shell of the light bulb. The protrusion or protrusions protrude out from the inside of the shell far enough to catch the heatsink. The protrusion or protrusions may be on top of the heatsink to prevent it from rising or below the heatsink to prevent it from falling. The protrusions exist both on top and below the heatsink to prevent it from either rising or falling. As the heatsink material typically expands less with temperature than does the shell material, the protrusions will continue to hold the heatsink in place during operation of the LED light bulb.
