Average Lumen Maintenance Projections
Lumen maintenance generally describes the ability of a lamp to retain its output over time. The useful lifetime for
solid state lighting devices (Power LEDs) is also defined as Lumen Maintenance, with the percentage of the original
light output remaining at a defined time period.
Based on long-term WHTOL testing, LED Engin projects that the LZ Series will deliver, on average, 70% Lumen
Maintenance at 65,000 hours of operation at a forward current of 1000 mA. This projection is based on constant
current operation with junction temperature maintained at or below 125°C.

Mechanical Mounting of MCPCB
MCPCB bending should be avoided as it will cause mechanical stress on the emitter, which could lead to
substrate cracking and subsequently LED dies cracking.
To avoid MCPCB bending:
o Special attention needs to be paid to the flatness of the heat sink surface and the torque on the screws.
o Care must be taken when securing the board to the heat sink. This can be done by tightening three M3
screws (or #4-40) in steps and not all the way through at once. Using fewer than three screws will
increase the likelihood of board bending.
o It is recommended to always use plastics washers in combinations with the three screws.
o If non-taped holes are used with self-tapping screws, it is advised to back out the screws slightly after
tightening (with controlled torque) and then re-tighten the screws again.
Thermal interface material
To properly transfer heat from LED emitter to heat sink, a thermally conductive material is required when
mounting the MCPCB on to the heat sink.
There are several varieties of such material: thermal paste, thermal pads, phase change materials and thermal
epoxies. An example of such material is Electrolube EHTC.
It is critical to verify the material’s thermal resistance to be sufficient for the selected emitter and its operating
conditions.
Wire soldering
To ease soldering wire to MCPCB process, it is advised to preheat the MCPCB on a hot plate of 125-150oC.
Subsequently, apply the solder and additional heat from the solder iron will initiate a good solder reflow. It is
recommended to use a solder iron of more than 60W.
It is advised to use lead-free, no-clean solder. For example: SN-96.5 AG-3.0 CU 0.5 #58/275 from Kester (pn:
24-7068-7601)

Company Information
LED Engin, based in California’s Silicon Valley, develops, manufactures, and sells advanced LED emitters, optics and
light engines to create uncompromised lighting experiences for a wide range of entertainment, architectural,
general lighting and specialty applications. LuxiGen™ multi-die emitter and secondary lens combinations reliably
deliver industry-leading flux density, upwards of 5000 quality lumens to a target, in a wide spectrum of colors
including whites, tunable whites, multi-color and UV LEDs in a unique patented compact ceramic package. Our
LuxiTuneTM series of tunable white lighting modules leverage our LuxiGen emitters and lenses to deliver quality,
control, freedom and high density tunable white light solutions for a broad range of new recessed and
downlighting applications. The small size, yet remarkably powerful beam output and superior in-source color
mixing, allows for a previously unobtainable freedom of design wherever high-flux density, directional light is
required.
LED Engin is committed to providing products that conserve natural resources and reduce greenhouse emissions.
