摘要： A lamp has a mechanism for allowing rotational slippage between a lamp body and an electrical connector when an applied torque is too large. This prevents damage during rotational coupling of the lamp, via the electrical connector, to a socket.

摘要： A LED lighting bulb (10) has a lighting driver (28) which is located within the bulb envelope (12). During assembly, the lighting driver (28) may be positioned away from an opening (14) of the envelope (12) so that high temperature sealing of a stem portion (22) of the end cap (16) to the envelope opening (12) can take place. The lighting driver (28) can then be pulled into position against the stem portion (22), and assembly of the end cap (16) can then be completed.

摘要： In order to provide a balance between a fast start-up in start-up phase and a low light output ripple in normal operation phase, it is provided a LED driving circuit comprising: an input to receive a LED driving current, a buffer circuit adapted to buffer said LED driving current, and an output to be connected to LED and adapted to output the LED driving current, after buffered, to the LED, characterized in that, further comprises a buffer adjustment circuit adapted to adjust the buffer capability of the buffer circuit at a first level, in a start-up phase of the LED driving circuit when the LED driving circuit starts to receive said LED driving current, and adjust the buffer capability of the buffer circuit at a second level larger than the first level in a normal operation phase later than the start-up phase.
