Smart Midnight ClockDIM allows dimming to predefined light levels
based on the nightly operating time. With flexibility in setting time
and light levels, the user can configure the driver for specific
locations and application needs. Using Integrated Dynadimmer, it
is possible to set up to 5 dim levels and time intervals. The driver
does not have a real time clock. Instead it runs a virtual clock,
determined by the length of nightly operating hours. After 3 ON-
OFF cycles, the driver will calculate the virtual clock time. A valid
ON-time is defined as a period during which the driver operates
continuously for ≥4 hours to ≤24 hours. For example, if the
requirement in summer is: 23:00-00:00: 75%, 00:00-04:00: 50%,
04:00-05:00: 75% (other time 100% or Off). The driver should be
powered on for 7h, so it can calculate the virtual clock time as
Allow users to separate 24hrs into 5 sections and corresponding output
current.
The driver will be in constant output mode.

23:00-00:00: 75%, 00:00-04:00: 50%, 04:00-05:00: 75%. From
summer to winter, the valid ON-time changes day by day. The
driver should be powered on for 17h in winter, and it also can
calculate the virtual clock time as 17:00. Then the dimming plan is
17:00~23:00: 100%, 23:00-00:00: 75%, 00:00-04:00: 50%, 04:00-
05:00: 75%, 05:00~10:00: 100%. From the above, if we set the
dimming plan as shown in the picture, after repeating the driver
ON-time for 3 consecutive days, the dimming plan takes effect
from the 4th day onwards. Each day the driver powered on, it has
a different start time according to the virtual clock time. So the
driver can satisf
different re
uirements for different seasons.
User can check how much time the driver works through this function.

Traditional light sources suffer from depreciation in
light output over time. This applies to LED light
sources as well. The CLO feature enables LED
solutions to deliver constant lumen output through
the life of the light engine. Based on the type of
LEDs used, heat sinking and driver current, it is
possible to estimate the depreciation of light output
for specific LEDs and this information can be
entered into the driver. The driver counts the
number of light source working hours and will
increase output current based on this input to
enable CLO.
When the CLO feature is enabled, the driver
nominal output current will be defined by the CLO
percentage as shown by the equation below:
Driver target nominal output current = CLO
percentage * AOC. For example, in the CLO
profile shown in Figure, between 52,000-60,000
working hours, the CLO percentage is set at 98%.
Assuming the nominal AOC is set to 500mA, the
driver output current with CLO enabled will be 0.98
x 500 = 600 mA.
The CLO percentage can be set to a value
between 85%-100%, in increments of 1%. The
LED module working hours can be set at any value
between (0-100,000 hours).
