The new 15W and 25W Mega Zeni light-emitting diodes (LEDs) from Sharp are suitable for use in street and object lighting, spot lighting, downlights and recessed ceiling light fixtures.

The LEDs are compact, lightweight, economical and extremely bright, according to the company.

The new models produce a light output of up to 2,550 lumens (depending on the module), a luminous flux of up to 102 lumens per watt and a long service life of 40,000 operating hours at a service temperature of 80C.

The 15W and 25W variants measure 24 x 20 x 1.8mm and have an aluminium ceramic plate as the carrier material.

The 15W Mega Zeni modules are operated using a forward voltage of 37V and a forward current of 400mA.

With the 15W Sharp Mega Zeni series, the round LED matrix consists of a total of 96 LEDs that are arranged in eight parallel-switched series of twelves.

The luminous flux is between 1,350 and 1,520 lumens (4,000K 102 lumens per watt).

The 25W Mega Zeni modules also have a forward voltage of 37V but are operated using a forward current of 700mA.

With the 25W series, the round LED matrix consists of 168 LEDs that are arranged in 14 parallel-switched series of twelves.

The luminous flux is between 2,300 and 2,550 lumens (4,000K 98 lumens per watt).

The serial and parallel array of the LED matrix ensures fail-proof operation while offering the lowest possible thermal emission.

The flat surface of the ceramic plate and the soldering points already in place make it possible to attach the modules to a suitable heat sink without too much effort or additional connecting material, thus guaranteeing excellent heat dissipation.

The colour temperature of the new white-light LED lighting modules lies in the range of 2,700-4,000K.

With regard to the CRI values and the colour temperatures, the Mega Zeni LED modules correspond to the requirements of the international Energy Star programme.

They can be fitted in new LED lighting systems and in places where light sources were previously used.

Until now, it was difficult to make energy consumption savings in lighting without compromising on light quality in the process.

In many challenging applications, it is not enough to install just one LED as a source of lighting.

In cases such as these, several LEDs are used, with the drawback that the light source takes up more space, thus making it more difficult to control and adjust the individual LEDs.

The Mega Zeni models will provide a solution to these problems in the future, according to Sharp.
