So what color was that dress?
In the grand scheme of things- not newsworthy, yet it made international news. As for why it looked different? Several factors come together- and it has nothing to do with the psychobable that the US underwater basket weavers want you to believe. 648 more words
Last week we dealt with Color Rendering Index or CRI, today I thought we’d deal with the concept of Color Temperature. If you’ve been thinking about specifying LED then you know at least a little it about the subject, but it’s so important to how we actually experience light that it bears discussion. 894 more words
LED street light emitting diode leds the semiconductor lighting. It is a kind of based on semiconductor PN junction formation with a weak electricity can light the high-efficiency solid-state lighting in certain positive bias voltage and injection of electrical flow electronic injection holes and injection of N P area area after spread to have source area by the radiative recombination and emit photons convert electrical energy directly into light energy. 852 more words
