figure 4: improved driver performance for the mX-6s Led
The choices change when moving to the brighter 60-w-equivalent leD lamp. very high
efficacies can be achieved with large numbers of LEDs, but it is an impractical amount of
money to be spent on leDs, and the space constraints of the bulb will not permit it. In
practice, the 800-lumen target is achieved with a few additional parts and with an increased
thermal load in the system. For this part of the exercise, we are assuming a higher junction
temperature of 85 °c. The two cost-effective leDs for this bulb are the Xp-e Hew and
the CXA2011. The PCT is again configured to illustrate numbers of LEDs, system lumens,
system power and efficacy.
