Features:
1. The ceramic era of the COB LED light engines
with this 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 Lior 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
2. In white light production by means of color conversion using a potting material, which is mixed with phosphor, a color conversion pigment. Lior provides MCOB LED modules with white light in a bandwidth which ranges from warm-white to a cold white. In addition to standard color temperatures such as 2700K (warm-white) to 4200K (neutral white) to 6500K (cool white), we also offer as customer design.
3. Useful lifetime estimates for LED lighting products are typically given in terms of the expected operating hours until light output has diminished to 70% of initial levels.
Lior MCOB LED use quality dies, substrate, phosphor and encapsulated materials; Together with very strict tests to ensure our MCOB meet the industrial standard.
Lior 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. Lior 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.
Lior high-power LED modules which is suitable for lighting applications anywhere such as:
Down light
Pendant light
Spotlight
Landscape light
Road lighting
The light from LEDs contains less infrared light (heat) than thatfrom a conventional incandescent lamp, so the LED is adaptableto lighting applications where items may be susceptible to damagecaused by temperature rise. It is also an excellent fit for lighting items where there is a concern ofdeterioration 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 reducewaste. LEDs contain no hazardous substances, convert energy to lightin an efficient manner, meaning less heat output for a given amount oflight and less need for space conditioning.
