Thanks to the use of this innovative platform, LED lighting fixtures become future-proof. In this way it is possible to use technological advances to improve the efficiency of lighting systems with LED and reduce costs. A LED lighting fixture designed based on the MCOB LED automatically takes advantage of the progress of the development of LED, without expensive modifications to the basic design.
With the system "Multi Cups / chip on board", the low-power chips are arranged in a specific gradation and covered by a layer of phosphor. The advantages of this system are an extremely homogeneous distribution of light and a light-emitting surface extremely slow.
The MCOB LED light engine includes variants from 400 to 5000 lumens with a luminous efficiency of up to 100-130 lumens per watt. The modules of 57 mm diameter circular offer a choice of color temperatures between 2,800, 4,500 and 6,500 Kelvin with a color rendering index (CRI) of between 75 and over 85.
The LED light engine MCOB Core are based on 3 different principles:
|Thermal resistance (K/W)||0.3|
|Thermal Conductivity (W/mK)||29.3|
6 grooves on ceramic plate with function of anti-interference and anti-static. Gold foil encapsulation increases LM/W up to 130LM/W. But cost is higher.
|Thermal resistance (K/W)||0.3-0.5|
|Thermal Conductivity (W/mK)||0.8-4.5|
Silver conducted on SIOX surface. Gold foil encapsulation. 130LM/W . Crystal glass has insufficient heat dissipation
|Thermal resistance (K/W)||0.75|
|Thermal Conductivity (W/mK)||225|
6 grooves on Aluminum base, insulating treatment. Gold foil integrated circuit packaging . Luminous efficacy increased to 130LM/W. However, conductive problem should be paid attention to.
