LED floodlight (thermogram). Shown here is a thermogram of an LED floodlight. Compared to conventional incandescent light bulbs, LEDs are much more efficient, durable, and have longer lifetime. Solid-state lighting is expected to eventually replace conventional incandescent and even fluorescent light bulbs. Thermography is a technique for visualizing the temperature of objects by recording the thermal emission intensity at long infrared wavelengths. This image was acquired with a specialized camera that uses a focal-plane array of vanadium oxide microbolometers as a sensor. It is sensitive to electromagnetic radiation in the wavelength range of 8 to 14 micron. The camera produces a 320x240-pixel image where different colors correspond to different temperatures.
