Selection of color rendering property, light source color temperature and light decline index of yaorong LED lighting lamps
First, choose lumen/watt high yaorong LED lighting fixtures
Luminous flux, namely the total amount of visible light emitted by the light source in unit time, unit: lumens (Lm).Luminescent efficiency refers to the light energy (commonly known as luminous flux) emitted by the light source per W of electric power, unit: lumen/watt (Lm/ W). It refers to the comprehensive luminous efficiency of a finished LED street lamp.Under the rated voltage, the total luminous flux emitted by the LED lamp divided by the total power consumption of the LED lamp, that is, the comprehensive luminous efficiency of the LED lamp, expressed by lumens/watt, the higher the value, the better the effect of the lamp, the more electricity saving.Under the same power, the lamps and lanterns with high luminous efficiency, large luminous flux, are brighter and more energy saving!The 3W LED bulb is higher than the 18W CFLs.And that’s about eight times the ratio of a 40W incandescent bulb.
Two, choose the color rendering index of high products
Colour rendering refers to the color of the object under light irradiation and the true color of the degree of proximity.The larger the color rendering index “Ra” value is, the closer the color of the object is to the real color.It is generally believed that: 80 ~ 100, excellent color rendering;50 ~ 79, color rendering is general: < 50, color rendering is poor.yaorong LED lighting fixtures with high color rendering index should be selected.
Third, the choice of light source color temperature according to personal preferences
Its unit of color temperature is Kelvin (K), the color temperature of the red light source is about 800K ~ 900K, the color temperature of the yellow and white light source is about 3000K, the color temperature of the white light source is about 5500K, the color temperature of the light blue light source is about 8000K ~ 12000K.The choice of light source color temperature depends on each person’s preferences, some people like warm colors, so 3000K color temperature lamp is suitable for him, like daylight color of 5000K ~ 6500K color temperature lamp can meet the requirements, like cool colors, choose 8000K~12000K yaorong LED lighting lamps.
