Do LED lights really save money? The answer definitely is Yes.
LED lights are small:
An LED is basically a small piece of crystal encapsulated in epoxy resin, so it’s very small, very light.
Low power consumption: LED power consumption is very low, generally the working voltage of LED is 2-3.6v. The working current is 0.02-0.03A. That is: it consumes no more than 0.1W of electricity.
Long service life:
LED service life can reach 100,000 hours with appropriate current and voltage. High brightness, low heat, environmental protection: LED is made of non-toxic materials, unlike fluorescent lamp, which contains mercury, which will cause pollution. At the same time, LED can also be recycled and reused.
Strong and durable:
LEDs are fully encapsulated in epoxy resin and are stronger than bulbs and fluorescent tubes. There is no loose part in the body of the lamp. These characteristics make LED not easily damaged.
High brightness, energy saving, high efficiency, fast reaction speed, good shock resistance, long service life. To illustrate the characteristics of white LED, first look at the current use of the light source. Incandescent lamp and halogen tungsten lamp, its luminous efficiency is 12 ~ 24 lumens/watt; Fluorescence of fluorescent and HID lamps is 50 to 120 lumens per watt.
For white LED: in 1998, the white LED lights only 5 lumens per watt, in 1999 has reached 15 lumens per watt, which similar to the general household incandescent lamp, and in 2000, the white LED lights to have 25 lumens/watt, this index close to halogen tungsten lamp.
In 2005, the light efficiency of LED reached 50 lumens per watt, and in 2010, the light efficiency of LED reached more than 100 lumens per watt. The working current of white LED can reach amperage level. Therefore, it can be seen that it will be possible to develop a white LED writer’s lighting source.
