Light&Light™ - A19 LED Bulb Technology


Light&Light™ - A19 LED Bulb Technology

The A19 Light&Light™ LED bulb, which was selected as a winner of the 2012 R&D 100 Awards, utilizes thermal-conductive plastic instead of the traditional metal for cooling to obtain 90% high optical efficiency advantages and can meet different light distributions of lighting environments through optimizing the flexible LED module and plastic heat-sink design.

Without the need of secondary optics, this omnidirectional bulb can deliver a 300 degree illumination angle easily, and it can provide a more uniform and comfortable lighting environment with consistent and sufficient luminous flux output. It can save 85% of the energy and deliver 35 times the lifetime of traditional bulbs. Thus, the technology enables us to fully replace traditional 60W and 75W incandescent lamps with bulbs of much higher efficacy of 100lm/W.

This innovation can be applied to interior lighting applications, such as lighting retrofits or wide illumination angle light-weight luminaire. Currently, the technology and patent of these technologies have been licensed and transferred to the Tyntek company for implementation of mass production.
