A stage light with a defogging device includes a light head, in which a mounting plate for fixing a light source and a supporting plate for mounting optical lens are arranged. At a light outlet of the light head a light emitting lens is provided, a light source cavity is formed by the supporting plate, the mounting plate and a side wall of the light head. A blower is arranged in the light source cavity, which is configured to guide airflow into space between the supporting plate and the light emitting lens through an air guiding element. Hot airflow in the light source cavity is guided into the space between the supporting plate and the light emitting lens, so that the temperature of the space between the supporting plate and the light emitting lens is increased, thereby reducing a temperature difference in the light head to avoid water fog.

Provided herein is a high intensity discharge light source having a thermally insulative and optically transparent sleeve for maintaining or enhancing a spectral performance parameter. The configuration of the sleeve provides an insulative volume that allows an elevated steady state operating temperature to be reached, even when the light source is cooled. The sleeve is also configured to withstand a bulb failure event, thereby protecting the surrounding environment from falling debris. Also provided herein are methods for dissipating heat from the light source without adversely affecting the bulb operating temperature or the enhanced spectral performance parameter.

Disclosed herein is a display apparatus having a cooling path provided to enhance cooling efficiency. The display apparatus includes a display panel configured to display images; a light source configured to radiate light toward the display panel; a bottom chassis disposed in rear of the light source; a case provided in rear of the bottom chassis; a circulative cooling path provided as to have air circulated surroundings of the bottom chassis.
