 Sharp Microelectronics unveils new 50W Mega Zeni LED array

Ismosys has released details of Sharp Microelectronics new 50W LED module, the latest addition to the manufacturer’s Mega Zeni series of LED modules.

The 50W Mega Zeni is one of the first industrial LED solutions capable of replacing traditional 50W HID lamps in the same performance class. It maintain the same compact dimensions and high CRI values of earlier Mega Zeni modules but offers considerably greater luminous flux. The 50W Mega Zeni features a luminous efficiency of between 3590 and 4770 lm, a light output of up to 100 lm/W in standard operating mode and a long service life of 40,000 hours at an operating temperature of up to 90°C. Designed for a forward voltage of 50V and a forward current of 950 mA, the new module can also be operated with a standard power source of 1050mA. Other important features include: R9 values of over 85 with CRI values of over 90, MacAdam 3-step Ellipse binning, as well as excellent colour consistency and stability over time under realistic operating conditions (hot lumen). 

The round light emitting surface (LES) of the new 50W Mega Zeni module comprises a total of 160 LEDs, sub-divided into ten parallel-connected rows of sixteen. It’s a feature of all Sharp Mega Zeni devices that the LES is fitted evenly with LEDs from edge-to-edge in order to avoid the formation of multiple shadows and making it easier to focus the optics (lens, reflector) onto a single light emitting surface. The slim design of the new 50W Mega Zeni (24mm x 20mm x 1.8mm), together with its small LES increases design flexibility and opens the door to smaller optics and ultimately smaller lamps.

According to Ismosys MD Nigel Watts, the serial and parallel array of the new Mega Zeni LED matrix ensures fail-proof operation while offering the lowest possible thermal emission: “The flat surface of the ceramic plate and the soldering points provided enable the module to be easily attached to a suitable heat sink without additional connecting material, thus ensuring excellent heat dissipation”, Watts said. ”The design of the module’s electrical wiring also leads to lower thermal stress as heat is evenly distributed and dissipated across the entire surface of the matrix. Compared to halogen lamps the 50W Mega Zeni LED array exhibits a much lower decrease in brightness over time and at 40,000 hours, a much longer overall service life”.

The colour temperature of the new white light LED lighting components ranges from 2700 to 4000 Kelvin. The CRI values and colour temperatures of the new  Mega Zeni LED modules correspond to the requirements of the international Energy Star programme. Overall, the new 50W Mega Zeni LED arrays are characterised by a high quality of light and high performance in a compact form, making them eminently suitable for illumination of areas and objects outdoors as well as for indoor applications such as spot lighting, recessed ceiling light fixtures, etc.

The new Sharp 50W Mega Zeni LED module is sampling today, initially in 3000 and 4000K colour temperatures versions .
