< p > single light color rendering, refers to under this kind of light irradiation, reductive degree by the color of the object, the unit is a percentage. For example, on a clear morning without haze, held out his hand to undertake, sun color reduction is a good, color rendering up to 100%. < / p > < p > < / p > < p > only the moonlight night, stretched out his hands to undertake the moonlight, you can discover, color looks blue. This is an old saying 'night view color', it is during the is given priority to with the moonlight under the condition of light source, poor color rendering. The posterity of moonlight color rendering in 35% probably Between 70%, volatile. < / p > < p > < / p > < p > in recent years, with the fluorescent lamps and leds ( Light emitting diode) Began as a lighting source gradually into the people's attention, the object under the sun, will show its true colors, but when the object in a continuous spectrum of gas discharge lamp, under the irradiation of color will have different degrees of distortion. < / p > < p > < / p > < p > led lamp line of light color is higher than high pressure sodium lamp, high-pressure sodium lamp only around 23, color rendering index and the led line light color rendering index above 75, think in terms of visual psychology, to achieve the same brightness, led line lights can be the average illuminance more than 20% lower than the high-pressure sodium lamp. Light failure is small, light failure is less than 3% a year, still meet the requirements of the road to 10 years, and high pressure sodium light failure is big, has fallen by more than 30% a year or so, therefore, the led light on the design of the use of power lines can be lower than the high-pressure sodium lamp. automatic control and energy saving device, can realize under the condition of meet the requirements of lighting in the different periods may reduce power, saves the electricity. Can realize the computer dimming, period and control, light control, temperature control, humanized functions such as automatic inspection. < / p > < p > < / p > < p > general led linear light different colors have different luminous intensity, commonly used unit is the MCD, namely the milli candela. The higher the value, the greater the luminous intensity, that is, the more bright. This is one of the important indicators, assess the led lamp brightness line higher brightness demand line lamp, the more expensive. This is because of high brightness led chip price is too expensive, and the higher brightness, encapsulates the greater difficulty. < / p > < p > < / p > < p > led line lamp has a unique secondary optical design, the lines will be led lamp light to the required lighting area, further improve the efficiency of the light, in order to achieve energy saving purpose. Led has reached 110 - 130 lm/W, also has the very big development space, and the theoretical value of 360 lm/W. And high pressure sodium lamp luminous efficiency was increased with the increase of power, as a result, the overall led lighting lamps are better than high pressure sodium lamp lines; ( The overall smooth effect is theoretically, in fact, more than 250 w high pressure sodium lamp light efficiency is higher than led lights) 。 < / p > < p > < / p >
These led rgb panel custom size led panel are meant to serve as a guide for business owners on how to both identify potential opportunities for transformative innovation and how to adapt to the constantly changing technologies of today.
