LEDs (Lighting Emitting Diodes) are semiconductor elements that directly convert electrical energy into light via electro-luminescence. The outstanding characteristics of LEDs include robustness, long funtional life and a high luminous efficacy with high potential for further increase.

With the breakthrough of the LED as a viable light source across a wide front, we are currently experiencing a far-reaching technological upheaval. This is comparable with the transition from telegram to SMS on mobiles. Their enormous potential, both in terms of efficiency and regarding lighting quality and visual comfort, means that light emitting diodes will be the light source of the future. In particular, they are an alternative to incandescent lamps and tungsten halogen lamps which are known to be poor in terms of energy efficiency.

It is at such times of change that there is a rise in the requirement for bona fide information, e.g. what are the specific properties of LEDs for lighting? What are their advantages compared with conventional lamps? How do LED lighting tools operate? What factors govern their efficiency in practical applications? What design possibilities do LED luminaires offer for lighting designers and to what extent does this alter design processes and cause paradigm changes?

LED lighting is the most energy-efficient lighting in history, producing energy savings of up to 80 percent when compared to traditional halogen lighting. HTA LED lamps and luminaires are rated with an average life of over 30,000hrs, all while being able to deliver superb thermal management and reliable and consistent light output. Our quintessence self-designed floodlight Q2 series, for instance, incorporate high-power LED chips with well-ventilated aluminium die-cast housing, reached the most delicate balanced lighting solution in efficiency and lifetime. A 25W Q2 outperforms a traditional 150W lamp in every facet, with a power factor >0.9, Ra>75, IK08, IP65, and a 30,000hrs lifetime, entitle HTA to revolutionize the industry as the pioneer in energy-saving solutions.
