摘要： The present high-pressure discharge lamp is composed of an arc tube part having an internal space, a pair of tungsten electrodes disposed in opposition to each other within the internal space, and mercury and halogen encapsulated in the internal space. The halogen is excessively encapsulated into the internal space relatively to the capacity of the internal space so as to establish an appropriate halogen cycle when the mercury partially deposits without evaporating.

摘要： It is an object of the present invention to provide a lighting circuit for and a lighting method of a high-pressure discharge lamp whereby remarkable reduction in illuminance maintaining rate can be avoided by reducing variation in inter-electrode distance in the beginning of usage without modulating a lighting frequency. The object can be achieved by a lighting circuit configured to light a high-pressure discharge lamp by supplying an alternating lamp current, which includes at least one pulse current superimposed on the former half of each half period of a base lamp current and at least two pulse currents and superimposed on the latter half of each half period, to the high-pressure discharge lamp.

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.
