LED light tube end cap with self-docking driver comm board
First Claim
1. An LED light tube assembly comprising an LED light tube comprising an LED board mounted in a tubular housing including a translucent cover and a sidewall portion opposite the translucent cover, and a removable end cap assembly with external electrical connector terminals, wherein:
- the end cap assembly comprises an end cap having a sidewall, and a driver board extending axially from the end cap at a first midpoint level corresponding to an underside of the LED board;
a connector tongue extending axially from the cap sidewall generally parallel to and spaced radially from the driver board at a second level corresponding to the sidewall portion of the tubular housing, the connector tongue configured to mate with an outer end portion of the sidewall portion of the tubular housing to axially and rotationally secure the cap assembly to the LED light tube;
spring-biased power supply terminals on an upper, outer end surface of the driver board configured to engage an upper surface of an outer end of the LED board when axially assembled thereto;
wherein,when the end cap is in an assembled condition on the LED light tube, the driver board extends underneath and generally parallel to the LED board, with an inner end of the driver board suspended in free fashion in the LED light tube beneath the LED board.

Abstract
An LED light tube assembly comprising an LED light tube with an LED array board in a tubular housing, and an end cap with a driver board removably secured to the end of the LED light tube. The driver board extends from a cap midpoint at a first level corresponding to an underside of the LED board in the tube, and the cap includes a connector tongue spaced from and parallel to the driver board at a second level corresponding to a portion of the sidewall of the tubular housing. The driver board further includes spring terminals that frictionally engage an upper surface of the LED board as the cap is assembled to the light tube, while remaining assembly and connection forces are borne by the cap and the tubular housing.
