Description
Flat Top Package
The Series flat top
lamps use an untinted, non-
diffused, truncated lens to provide
a wide radiation pattern that is
necessary for use in backlighting
applications. The flat top lamps
are also ideal for use as emitters
in light pipe applications.

2. Refer to Figure 7 to establish pulsed operating conditions.
3. Derate linearly as shown in Figure 6.
4. The transient peak current is the maximum non-recurring peak current the device
can withstand without damaging the LED die and wire bonds. It is not
recommended that the device be operated at peak currents above the Absolute
Maximum Peak Forward Current.

Notes:
1. The luminous intensity, Iv, is measured at the mechanical axis of the lamp package. The actual peak of the spatial radiation pattern
may not be aligned with this axis.
2. f
v
is the total luminous flux output as measured with an integrating sphere.
3. The dominant wavelength,
l
d
, is derived from the CIE Chromaticity Diagram and represents the color of the device.
4. q
1
/
2
is the off-axis angle w here the luminous intensity is 1/2 the peak intensity.
5. Radiant intensity, I
v
, in watts/steradian, may be calculated from the equation I
v
= I
v
/h
v
, where I
v
is the luminous intensity in candelas
and h
v
is the luminous efficacy in lumens/watt.
