Lighting emergency gear – what waveform should we use?

This article explains the pitfalls in providing DC or a modified sinewave to drive LEDs in emergency mode. Many LED luminaires have built-in drivers, so emergency gear must either simulate mains or attempt to drive the LED with DC power. Lower-power LEDs with low power factors are easiest to drive due to their simple circuitry. […]

New waveform lidar product range launched

Riegl Laser Systems has launched and showcased an extensive range of waveform lidar products at this year’s InterGEO in Stuttgart, Germany. Its new VQ-780II and VQ-1560II airborne laser scanning systems (with a pulse repetition rate of 2 MHz and 4 MHz respectively) increases productivity for both high-point-density mapping and ultra-wide-area mapping. Furthermore, the VP-1 Helicopter […]
