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.

The present invention refers to a lighting device (10) and a method of operating this lighting device (10). A lighting module (13) having a light element series connection (15) of several semiconductor light elements (14) is connected to the output (12) of a drive circuit (11). The control means (20) is provided which is configured to adapt a heating condition if a heating requirement is fulfilled. In the heating condition a heating means (26) is activated by the control means (20) to heat the lighting module. The heating requirement is fulfilled when the temperature (T) of the lighting module (13) drops down to a minimum temperature value (Tmin). In so doing an undesired increase of the forward voltage (Vf) of the light element series connection (15) can be avoided.
