Abstract:
The present invention relates to an illuminating device (100) comprising: a base (1), the base (1) comprises a partition board (13) dividing the base (1) into a first accommodating cavity (11) and a second accommodating cavity (12); a circuit board (2) having light sources (21) and arranged in the first accommodating cavity (11); and an optical assembly (3) arranged at an opening end of the first accommodating cavity (11), and wherein the partition board (13), the circuit board (2) and the optical assembly (3) each have at least one air communication structure to enable air from environment to flow into the first accommodating cavity (11) and the second accommodating cavity (12).
Abstract:
Provided is a LED tube comprising a PCB (2), light emitting diodes (LEDs) serving as light source and a LED driver (6) fixedly disposed on the PCB with the LEDs. The LED tube further comprises a switchable optical cover (5), in which the PCB together with the LEDs and the LED driver that are disposed on the PCB are mounted. The switchable optical cover (5) allows the LED tube to switch between a fully transparent condition and a partially transparent condition. Therefore, a user is allowed to choose conveniently between a high efficiency LED tube and a glareless LED tube according to actual requirements, and does not need to store and replace the entire LED tube.
