摘要:
A method of lighting a high-pressure discharge lamp (X) is configured to change a power to be supplied to the high-pressure discharge lamp (X) in accordance with a luminance parameter (P) of an image content (C). The method includes switching between a low temperature operation and a high temperature operation so as to maintain a condition that mercury (30) encapsulated into an arc tube part (18) of the high-pressure discharge lamp (X) constantly partially deposits without evaporating. The low temperature operation is performed where the temperature in the arc tube part (18) is less than or equal to the deposition temperature of the mercury (30), whereas the high temperature operation is performed where the temperature in the arc tube part (18) is greater than the deposition temperature of the mercury (30).

The invention relates to an electric high-pressure discharge lamp (10) for a cosmetic skin treatment, comprising a fluorescent tube (20) of quartz glass, wherein at least two electrodes (21) made of metal having a mutual spacing greater than the internal diameter of the fluorescent tube (20) are disposed in the fluorescent tube (20), wherein a gas is enclosed in the fluorescent tube (20) and the quartz glass is doped with copper and tin, whereby the transmission of the fluorescent tube (20) for electromagnetic radiation of a wavelength shorter than 550 nm is reduced. The invention further relates to the use of such an electric high-pressure discharge lamp in a tanning apparatus or lamp for cosmetic skin treatment.

A light source apparatus wherein it is possible, for example, to mount a discharge lamp to a mounting mechanism easily in a short amount of time, is provided. A light source apparatus is equipped with a discharge lamp (1), which has a glass tube (25) that forms a light emitting part and a base member (26) that is coupled thereto, and a mounting apparatus (31) that holds the discharge lamp (1) via the base member (26). Therein, the base member (26) has a flange part (26a) that contacts positioning plate (50) of the mounting apparatus (31), and a fixed part (26h) that is urged with a pressing force that presses the flange part (26a) to the positioning plate (50). Furthermore, the mounting apparatus (31) has a fixing arm (5 5A) that urges the fixed part (26h) by a compression coil spring (44A).

Disclosed are a lighting method for a high-pressure discharge lamp, a lighting apparatus for a high-pressure discharge lamp, and a high-pressure discharge lamp apparatus each suppresses abnormal blackening of a discharge tube that may occur at an initial stage of operation from a discharge start. According to the lighting method of the present invention, the lamp current is reduced upon detection, by an abnormal discharge detector 5021, of an abnormal discharge that is produced between a tip of one electrode and a root of the other electrode.

A high-pressure mercury lamp includes an arc tube, and a pair of electrodes is provided in a discharge space of the arc tube. In the discharge space, mercury and xenon gas are sealed. The amount of mercury per unit volume that is to be sealed in the discharge space is within a range of 0.12 mg/mm 3 to 0.35 mg/mm 3 . A pressure of the xenon gas in the discharge space is within a range of 2.0×10 5 Pa to 2.0×10 6 Pa.
