Patent attributes
A linear light-emitting diode (LED) tube lamp having a readily retrofittable modular structure enables consumers or manufacturers to readily retrofit the lamp by replacing an LED module or internal electronic control units that include an LED driver in maintenance or lamp upgrade without hazards. The readily retrofittable modular structure includes a core assembly in each of lamp bases for easily securing or removing the electronic control unit through a mechanical securing means, and two sets of connection modules for quickly connecting and disconnecting the electronic control unit with the LED module. The readily retrofittable modular structure may use one bi-pin or two bi-pins to connect to the AC mains via pluggable wire for delivering power to the LEDs. Thus, the LLT lamp using the readily retrofittable modular structure may be configured as single-ended, double-ended, or double-ended with double shock-protection switches and can be cost-effectively retrofitted after initial installation.
