Lumiere high-power MCOB LED modules, with an LED die array mounted on ceramic substrate, ensure
high luminous flux, high efficiency and radiation performance, no uncomfortable glare, low heat
resistance plus they offer high reliability. The existing LED applications, such has home lighting, have
relatively small power output; a move to higher-power applications means that engineers will have to
deal with more heat and durability problems. Lumiere high-power MCOB LED ceramics substrate
modules enable both high-brightness and high-durability for high-output LEDs, and have capability of
being molded into compact shapes.”
Lumiere high-power LED modules which is suitable for lighting applications anywhere such as:
The light from LEDs contains less infrared light (heat) than that from a conventional incandescent lamp,
so the LED is adaptable to lighting applications where items may be susceptible to damage caused by
temperature rise. It is also an excellent fit for lighting items where there is a concern of deterioration
or discoloration from ultraviolet rays, because the LEDs have no emission in the UV spectrum.
With global warming becoming a huge concern for the environment and more people looking at
eco-friendly alternatives, the LED lighting is being perceived as a way to achieve a greener earth. The
environment friendly LED lighting function high luminous efficiencies, high reliability, save more on
power, have a longer lifespan which, in turn, is what makes them environmentally friendly. LEDs offer
these and more: they save energy and reduce waste. LEDs contain no hazardous substances, convert
energy to light in an efficient manner, meaning less heat output for a given amount of light – and less
need for space conditioning.
With the MCOB technology, the LED chips are in the form of a semiconductor chip (die) size between
100~200 micron. The individual chips are placed on the ceramic substrate PCB and using the Wire
Bonding method, connected to the contact surface of the ceramic substrate PCB. Gold wires in the
micrometer range are used for contacting the semiconductor chip and the substrate. The COB
technology allows for virtually limitless freedom of scope for the PCBs and thus serves as the basis for
totally unique LED solutions. Furthermore Lumiere is using ceramic as substrate of which will improve
the internal quantum efficiency and increase heat dissipation. The careful design of the ceramic PCB
and selection of quality dies in consequences minimize electrical losses and light extraction on the dies
and improve the LED efficiency.
