Light source device
First Claim
1. A light-source device comprising:
- a lamp unit having a light-source lamp;
a container part for containing the lamp unit in a removable manner;
a counter for measuring illumination time of the light-source lamp when the lamp unit is installed in the container part;
a first antenna for sending the illumination time information measured by the counter to the lamp unit;
a second antenna, which is provided in the lamp unit, for receiving the illumination time information which is sent from the first antenna; and
a rewritable memory, which is provided in the lamp unit, for storing the illumination time information received by the second antenna.

Abstract
A light-source device includes a lamp unit having a light-source lamp and a device housing which is provided with a lamp-unit container for containing the lamp unit in a removable manner. The device housing includes a CPU for measuring the illumination time of the light-source lamp and an antenna for sending the illumination time measured by the CPU to the lamp unit. The lamp unit includes an RFID tag which is fixed thereto. The RFID tag is provided with an antenna for receiving the illumination time information sent from the antenna of the housing and a rewritable memory for storing the illumination time information received by the antenna of the tag.

14. A light-source device comprising:
-
a lamp unit having a light-source lamp;
a device housing having a container part for containing the lamp unit in a removable manner;
a counter, which is provided in the device housing, for measuring illumination time of the light-source lamp;
a first antenna, which is provided in the device housing, for sending the illumination time information measured by the counter to the lamp unit;
a controller, which is provided in the device housing, for demodulating the illumination time information received by the first antenna to output the information to the counter and for modulating illumination time information measured by the counter to output the information to the first antenna;
a second antenna, which is provided in the lamp unit, for receiving the illumination time information which is sent from the first antenna;
a rewritable memory, which is provided in the lamp unit, for storing the illumination time information received by the second antenna; and
a modulator-demodulator circuit, which is provided in the lamp unit, for reading and modulating illumination time information stored in the memory to output the information to the second antenna and for demodulating illumination time information received by the second antenna to write the information into the memory. - View Dependent Claims (15, 16)

17. A light-source device comprising:
-
a lamp unit having a light-source lamp;
a device housing having a container part for containing the lamp unit in a removable manner;
a rewritable memory for storing illumination time information of the light-source lamp;
reading means for reading the illumination time information from the memory;
