Abstract (en)
A lighting apparatus includes a base (220), a light-emitting module (240) fixed on the base, a shell (260) connected to the base to form a hollow space with a first volume, and an inert liquid (280) confined within the shell and the base and having a second volume. The first and second volumes are increased or decreased at a similar tendency or volume change rate in response to a temperature difference.
