Description
The LZ4-00D100 Dental Blue LED emitter contains three Dental Blue dice and one UV die
which provide superior radiometric power in the wavelength ranges specifically required for
dental curing light applications resulting in a significantly reduced curing time. With a 7.0mm x
7.0mm x 4.1mm ultra-small footprint, the LZ4-00D100 provides exceptional optical power
density making it ideal for use in dental curing devices. LedEngin’s Dental Blue LED offers
ultimate design flexibility with individually addressable die. The patent-pending design has
unparalleled thermal and optical performance. The high quality materials used in the package
are chosen to optimize light output, have excellent UV resistance, and minimize stresses which
results in monumental reliability and radiant flux maintenance.

exposure time (MET) between bake and bag and the floor life of maximum time allowed out of the bag at the
end user of distributor’s facility.
Average Radiant Flux Maintenance Projections
Based on long-term WHTOL testing, LedEngin projects that the LZ Series will deliver, on
average, 90% Radiant Flux Maintenance at 100,000 hours of operation at a forward current of
700 mA per die. This projection is based on constant current operation with junction
temperature maintained at or below 125°C.

1. Unless otherwise noted, the tolerance = ± 0.20 mm.
2. Thermal contact, Pad 9, is electrically connected to Pad 3. Do not connect any pad to the thermal contact, Pad 9.
When mounting the LZ4-00D100 onto a MCPCB, by default its dielectric layer provides for the necessary electrical
insulation in between all contact pads. LedEngin offers LZ4-20D100 or LZ4-40D100 MCPCB options which provides
for electrical insulation between all contact pads. Please refer to Application Note MCPCB Option 2 or Option 4, or
contact a LedEngin sales representative for more information.
