LED Indicating Lights

The main parameters of LED lamp:1, color: conventional color temperature: warm white (WW) 2700-3200k, natural light (NW) 4000-4500K, is white (PW) 6000-6500k CWF (CW) 7000-7500k [here cold white distinction and jewelry lamp of the cold white light, jewelry lamp of the cold white light general for 15000-20000K] in addition, red, green, blue and other single color beads Chang can also do.2, power: power LED bulb generally below 12W. Common LED bulb lamp power is divided into: 3W, 4W, 5W, 6W, 7W, 8W, 9W, 10w.3, the basic parameters: voltage and current voltage and current is LED bulb is very important. The grid voltage in different countries in the world and some voltage occasions are not the same. The common voltage is 12V, 110V, 220V, 85v-265v. The current into the input current and lamp current. First: input current: can be tested with power, different power is not the same as the standard instrument. Second: lamp current: general high power is between 300mA to 320mA-. A large current of the LED light attenuation effect, so the current stability is also very important. Lamp current and voltage can not give too much, otherwise it will seriously affect the service life of the LED lamp.
