摘要： A light emitting diode lamp is composed of a light emitting diode, a band-pass filter and a light angle adjuster. The filter has a light cutoff function to cut off a light ray with a specific wavelength. The light angle adjuster allows the light rays emitted from the diode to be incident on the filter at incident angles of less than or equal to a maximum incident angle up to which the filter is capable of exerting the light cutoff function. The light angle adjuster is a reflector. The diode is mounted to a bottom portion. The filter is mounted to an opening. On an imaginary cross section including the optical axis, an angle formed between the optical axis and a straight line is less than or equal to the maximum incident angle, the straight line connects the emission center and an edge of the opening.

摘要： A method of lighting a high-pressure discharge lamp is configured to change a power to be supplied to the high-pressure discharge lamp in accordance with a luminance parameter of an image content. The method includes switching between a low temperature operation and a high temperature operation so as to maintain a condition that mercury encapsulated into an arc tube part of the high-pressure discharge lamp constantly partially deposits without evaporating. The low temperature operation is performed where the temperature in the arc tube part is less than or equal to the deposition temperature of the mercury, whereas the high temperature operation is performed where the temperature in the arc tube part is greater than the deposition temperature of the mercury.
