Optional standard of LED replacement lamps

　　There are many types of LED replacement lamps, such as spherical LED light is designed to replace incandescent spherical energy-saving products, as well as LED par lights, and many other types of such products currently on the market, mostly in less than 10 watts (1 watt to 10 watts specifications), to replace the bulb wattage at 60 watts and below.

　　The marketing sold luminous efficiency LED lights integrated in the 60-100 lm / W, color rendering index between 60-90, color temperature is 2700-6500k, the life is about 20,000 --- 50,000 hours, all manufacturers of LED light indicator is not the same, for the species and many brands of LED lighting products, how do we choose the LED lamps that they need? General customers may not understand some of LED lamps expertise in order to make the average person to understand the performance of LED lamps; the following is the brief introduction.

　　1, LED replacement lamps integrated light efficiency means a finished luminous efficiency of LED lights, which at the rated voltage, the LED lights emit a total luminous flux divided by the total power consumption of the LED lights, the resulting value is the LED integrated luminous efficiency lamps with lumens / watt, more higher value indicate more better effect of energy saving, so that you should select lumens / watt high LED lamps.

　　2, LED replacement lamp color rendering index of 100 is generally considered: 80-100, the color is excellent, 50-79, the color in general, <50, the color is poor. So they should be selected high CRI LED lamps.

　　3, LED replacement lamp Color temperature is measured in Kelvin (K), the red light source color temperature of about 800-900K, yellow-white color temperature of about 3000K or so, a white light source color temperature of about 5500K or so, pale blue light color temperature 8000-12000K. Color temperature selection according to individual preferences, some people like warm color, then the color temperature of about 3000K lights on for him, the people who like daylight, and then the color is 5000K-6500K color temperature lamps can meet his requirements. The people who Like the cool colors, they should select 8000-12000K LED lights.

　　4, LED replacement lamp life is 100% luminous flux emitted, after a period of using, the light emitting efficiency is decreased, when it dropped to 70% of the initial luminous flux, the number of hours of the lamp life Select number of hours lamp life course, the longer the better.

　　5, LED replacement lamp temperature rise, the general license is 25 ℃ -30 ℃, the specific heat sink temperature is: Ambient temperature plus temperature rise is permitted on the heat sink temperature. When the ambient temperature is 37 ℃, LED lamp heat sink temperature is 37 +30 = 67 ℃, if you exceed this temperature, the temperature rise permitted this lamp is substandard. LED lamp operating temperature is the enemy, of course, the smaller heating, the better it is, s it indicated a high luminous efficiency of LED lights, LED lights in the selection of the same lamp power can be lit simultaneously for comparison. The other is the LED light heat sink temperature warming faster Description LED light thermal conductivity, high efficiency, and low thermal resistance.

　　In addition to these indicators, when choosing LED lights, you should be selected on the eyes no glare, soft lighting some, that the eye will not feel uncomfortable to see the light, it is best to have its milky lampshade LED lights emit light softer.
