Method and apparatus for storing lamp data
View Patent ↗A lamp memory module is provided for recording lamp serial numbers, providing a ‘lamp-inserted’ interlock for preventing operation of the lamp when the lamp is not properly installed, and for collecting and storing lamp operational data such as lamp use (time), lamp strikes and various system temperatures.
1. In a projector system having a lamp, the improvement comprising a lamp memory module for storing a projector serial number, position of said lamp in said projector system, operational information for said lamp, and times and dates for at least some of said operational information, said serial number and information being accessible after said lamp is spent, said lamp memory module mounted on an external surface of a lamp module.
2. The improvement of claim 1 , wherein said lamp memory module includes a safety inter-lock system for deactivating said lamp in the event said lamp is not properly installed.
3. The improvement of claim 1 , wherein said information includes at least one of lamp hours information, lamp strike information, time and date of a last temperature measurement, all system temperatures for previous 30 days of operation, and maximum and minimum temperatures measured.
4. The improvement of claim 3 , wherein said lamp hours information includes number of hours said lamp has been operated at low power, medium power and high power levels.
5. The improvement of claim 3 , wherein said lamp strike information includes total number of successful lamp strikes and total number of attempted lamp strikes.
6. The improvement of claim 3 , wherein said system temperatures include lamp compartment temperature, system controller temperature, air exhaust temperature and maximum and minimum ones of said lamp compartment temperature, system controller temperature and air exhaust temperature.
7. A method of operating a projector system having a lamp, the method comprising:
mounting a lamp memory module on an external surface of a lamp module;
pre-programming said lamp memory module with a serial number for said projector system and a position of said lamp in said projector system; and
collecting operational information for said lamp, and times and dates for at least some of said operational information, said serial number and information thereby being accessible for analysis after said lamp is spent.
8. The method of claim 7 , wherein said information includes at least one of lamp hours information, lamp strike information, time and date of last temperature measurement, all system temperatures for previous 30 days of operation, and maximum and minimum temperatures measured.
9. The method of claim 8 , wherein said lamp hours information includes number of hours said lamp has been operated at low power, medium power and high power levels.
10. The method of claim 8 , wherein said lamp strike information includes total number of successful lamp strikes and total number of attempted lamp strikes.
11. The method of claim 8 , wherein said system temperatures include lamp compartment temperature, system controller temperature, air exhaust temperature and maximum and minimum ones of said lamp compartment temperature, system controller temperature and air exhaust temperature.
12. A method comprising:
mounting a lamp memory module on an external surface of a lamp module
pre-programming said lamp memory module with a serial number of a projector system having a lamp; and
collecting operational information for said lamp, and times and dates for at least some of said operational information.
13. A projector system comprising:
a lamp module comprising a lamp; and
a lamp memory module to store a projector serial number and operational information for said lamp, and times and dates for at least some of said operational information, said lamp memory module mounted on an external surface of said lamp module.
