Features and construction
As with the majority of mid-power SMT LEDs
available, the construction of the APT Plus
consists of a preprocessed plastic housing
(pre-mold)
contacts.
In addition to mounting and electrical
connection of the LED to the circuit board,
the gold-plated (NiAu) leadframe also serves
to dissipate the heat that arises during
operation.
Figure 2: Internal construction of the
Advanced Power TOPLED Plus
Within the housing, the semiconductor chip
and the ESD diode are mounted to the
anode side of the leadframe and make
contact with the cathode side by means of
wire bonding.
For the Advanced Power TOPLED Plus, this
results in a typical thermal resistance of
40 K/W and ESD protection up to 2 KV
according to JESD22A-114D.
As the centerpiece and actual lightsource of
the Advanced Power TOPLED Plus, highly
efficient semiconductor chips of the latest
thin film technology are used.
The APT Plus is available in red, green and
blue as well as the white colors of Ultra
White and Warm White (Table 1).

Table 1: The different variants of the
Advanced Power TOPLED Plus
In contrast to the standard Advanced Power
TOPLED, the silicone encapsulant of the
APT Plus is formed into a lens.
The silicone casted lens serves as a cost-
efficient device to optimize efficiency, by
allowing most of the generated light to
directly leave the LED.
As opposed to a more expensive precision
molded lens, the casted lens is not intended
to serve as a high precision optical element,
due to its inherently larger lens shape
variations.
In many applications such as backlighting
and general illumination where narrow spots
are not required, the casted lens shape
tolerances will not have any noticeable
influence.
Figure 3 shows the radiation characteristics
of the APT Plus.
Through
installation height (only 2.25 mm), adapted
radiation characteristics and exceptional
light output, the APT Plus permits the
implementation of flat designs based on
direct-view backlighting.
When used for display backlighting, the APT
Plus,
achieves a color gamut of more than 120%
of the NTSC Standard, allowing truly brilliant
images to be displayed.
With these excellent characteristics, the APT
Plus offers an optimal ratio of brightness in
the application to system density with a
minimal number of LEDs, for flat backlighting
as well as illumination solutions.
