Led Lighting Technology
Operating Temperature This is the temperature of the environment in which the luminaire will be operated. All device life measurements issued by LED manufacturers are performed at different ambient temperature ranges. High ambient temperatures for a particular luminance will shorten the operating life of the device, and low temperatures will ensure that the LED will last longer than expected. Standard International is a measure of the intensity of lighting. One candela is a lumen / steroidal. It was previously referred to as edil candle Daha. The illumination intensity of a light source in a given direction is expressed in candela (cd). Depending on the respective direction, any light source will have many different illumination intensities. Since the intensity of illumination itself is a characteristic of the light source, the candela value in a certain direction remains the same regardless of the distance to the source.
