| SHORT-ARC TYPE METAL HALIDE LAMP 575W L5431 PATENT PENDING Long Life / 3000 hours FEATURES The Short-Arc Metal Halide Lamp, L5431, suited for the light source for projector, has achieved the average life time of 3000 hours. It will enhance the performance of LCD projector and over-head projector (OHP). LIFE CHARACTERISTICS HAMAMATSU TECHNOLOGY Double halogen cycle convection will supress the dissipation of the electrodes. TLSOB0029EA 100 L5431 80 RELATIVE RADIANT INTENSITY (%) 60 CONVENTIONAL LAMP 40 20 CONVENTIONAL TECHNOLOGY Crystalization of fused silica envelope has occured after 500 hours or so operation, which will reduce the light transmission. 0 500 1000 1500 OPERATING TIME (h) 2000 2500 3000 Subject to local technical requirements and regulations, availability of products included in this promotional material may vary.

SHORT-ARC TYPE METAL HALIDE LAMP 575W L5431 LONG LIFE MECHANISM HAMAMATSU has developed a unique technology (PATENT PENDING), called as double halogen cycle, which extends the average lamp life over 3000 hours. QUARTZ GLASS ARC UNIQUE "DOUBLE HALOGEN CYCLE" TECHNIQUE Outer gas convection suppresses the thermal reaction with the fused silica envelope thus protect it from crystallization. It maintains the envelope strength and light transmission even after 500 hours of operation. Inner gas convection assures the metal halogen cycle which minimize the electrode dissipation.
