Appeal 2007-3322
Application 09/947,094
an optical path between said sampling LED and said light
sensor, said optical path configured to prevent intrusion of light
not emitted from said sampling LED; and
a control mechanism in communication with at least said
light sensor, said control mechanism configured to adjust the
current flow in accordance with the light detected by said light
sensor,
wherein a direction of light emission from said sampling
LED is altered from a direction of light emission from the
remaining LEDs of said string.
7. Like claim 1, claims 11, 14, 18, and 26 each recites a limitation
requiring the direction of light emission from a sampling LED to be altered
from the direction of light emission from the rest of the LEDs in the same
string of LEDs (claims 11, 14 and 18) or the rest of the LEDs in the same
array of LEDs (claim 26).
8. Claim 31 does not recite any limitation concerning the direction
of light emission of any LED.
9. Claim 31 reads as follows:
31. A light emitting diode (LED) luminance sensing
system comprising:
an LED mount structure having a first side and a second
side;
a string of LEDs mounted on the LED mount structure
first side, the string of LEDs including a sampling LED and
configured to receive a current flow and, upon receipt thereof,
to emit light;
