LOW POWER CERAMIC GAS DISCHARGE METAL HALIDE LAMP WITH REDUCED GLOW VOLTAGE |
摘要 |
A low power ceramic gas discharge metal halide (CDM) lamp 10 capable of retrofitting into existing low power HPS lamp fixtures, the CDM lamp 10 having an elliptically-shaped ceramic discharge vessel 12 containing a mixture of the rare gases neon and argon at a fill pressure of at least 400 mbar, and a pair of electrodes (17, 18) extending into the discharge vessel 12, the electrodes (17, 18) having an electrode clearance ratio E=D1/D2 of at least 0.36, where D1 is the shortest distance from an electrode (17) tip to the inner wall of the central portion 13 of the discharge vessel 12 and D2 is the distance between the discharge electrodes 17 and 18. |
