Methods and apparatus for grounding an electrical device via a lampholder

摘要

A lampholder includes a housing and a plurality of electrical terminals. The lampholder is adapted to hold a light-emitting diode (LED) tube light assembly supported at two ends of the tube light. The lampholder includes at least one terminal that electrically couples before the remaining terminals located in the same housing to ensure a first-connect, last-disconnect electrical connection when inserting the LED tube light into and removing the LED tube light from the lampholder.

主权项

1. A lampholder for a light source assembly having a first end on which is disposed a grounding electrical contact and a pair of power electrical contacts, the lampholder comprising:
a housing into which the first end of the light source assembly is to be inserted; and a grounding electrical terminal and a pair of power electrical terminals disposed within the housing, wherein the grounding electrical terminal and the pair of power electrical terminals are spatially arranged relative to each other within the housing such that the grounding electrical contact disposed on the first end of the light source assembly will be engaged with the grounding electrical terminal before the pair of power electrical contacts disposed on the first end of the light source assembly can be placed into engagement with the pair of power electrical terminals upon insertion of the first end of the light source assembly into the housing.
