Description
The LZ4-00DB00 Dental Blue LED emitter provides superior radiometric power in the wavelength range specifically
required for dental curing light applications. With a 7.0mm x 7.0mm ultra-small footprint, this package provides
exceptional optical power density making it ideal for use in dental curing devices. The radiometric power
performance and optimal peak wavelength of this LED are matched to the response curves of many dental resins,
resulting in a significantly reduced curing time. LED Engin’s LZ4-00DB00 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.

Maximum DC forward current is determined by the overall thermal resistance and ambient temperature.
Follow the curves in Figure 10 for current derating.
2:
Pulse forward current conditions: Pulse Width ≤ 10msec and Duty Cycle ≤ 10%.
3.
LEDs are not designed to be reverse biased.

The standard soak time is the sum of the default value of 24 hours for the semiconductor manufacturer’s 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, LED Engin projects that the LZ Series will deliver, on average, 70% Radiant Flux
Maintenance at 65,000 hours of operation at a forward current of 700 mA. This projection is based on constant
current operation with junction temperature maintained at or below 125°C.
