Compared to conventional light sources, such as incandescent lamps and energy-saving lights, LEDs are much more energy efficient, last longer, and offer many new design possibilities.
Iodine Lamp and Incandescent Lamp: Iodine lamp is not only reduces the amount of evaporation of tungsten, but also extend the life time, increasing the operating temperature and luminous efficiency.
White symbolizes autumn- while growing the white rice, it corresponds to a metal(incandescent), it is associated with the West, a cold white glow of the moon and the planet Venus.
Mulou have two, I and my happy sister and two sisters lived on the second floor of the five in Guangdong earth, inside an incandescent lamp, five simple bed, bed sheets looked dirty, the quilt is a kind of very special flavor.
The detector itself can comprise at least one illumination source, for example at least one laser and/or at least one incandescent lamp and/or at least one semiconductor illumination source, for example, at least one light-emitting diode, in particular an organic and/or inorganic light-emitting diode.
For incandescent lamps and other thermal radiation sources, because their spectral distribution is close to that of blackbody, their chromaticity coordinate points are basically on the black body trajectory, and the concept of visible color temperature can properly describe the light color of incandescent lamps.
It was a stone house was short, the room where a dim incandescent lamp, one old and one small, two Tibetan artisans are carefully chipped silver, Tibetan women, often dressed in an elephant's back like a small hat ornament.
If you use an incandescent lamp for 8 hours and 2 years a day, it will cost you about $50, but if you use LEDs for 8 hours and 2 years in the same period- it will cost you low up to $2 to $4.
However, for other lights other than incandescent lamps, the spectral distribution is far from the black body, and the chromaticity coordinates determined by the relative spectral power distribution at their temperature T do not necessarily fall accurately on the black body temperature trajectory of the chromaticity diagram.
Finished back to waiting room, two dim incandescent hanging around his spider web high ceiling, near the ticket window full of shoe prints on the walls, there is one point I wondered, footprints and some two meters from the ground above, I do not know which martial arts masters to kick up it?
