 What is Power consumption ?
In electrical engineering, power consumption refers to the electrical energy per unit time, supplied to operate something, such as a home appliance. Power consumption is usually measured in units of watts (W) or kilowatts (kW).when you buy a led light to your home you may need small led like 7w to 20w



Pin Type
  • E27 LED Bulbs (ES)
  • E14 LED Bulbs (SES)
  • B22 LED Bulbs (Bayonet)
  • B15 LED Bulbs (Small Bayonet)
  • GU10 LED Bulbs.
  • G4 LED Bulbs.
  • G9 LED Bulbs.
  • MR16 LED Bulbs

Lumens
Lumen is how much light is produced by the led so with new high power led 1w it will be make about 100lm from the edison led it can be like 10w

lumens per watt
this is the imported thing when you are buying the led for exampe with
epi lumen for watt is 100
cree lumen for watt is  150
so if the new cree led is doubled lumins you can use 2w cree led insted 3w epiled

lights what is it? where does it come from ?what does light have to do with color ? life is a kind of energy that travels in waves it is made when matter is heated up or gains energy excess energy is released in part as light energy is called electromagnetic radiation. when we talk about light we usually mean visible light which is the light that we can see with our eyes but there are more types of electromagnetic radiation that are invisible to us putting radio waves microwaves X-rays and gamma-rays.     scientists can detect and measure invisible radiation with special tools because there was visible light all these types of radiation are called the electromagnetic spectrum all electromagnetic radiation travels in waves but different types have different wavelength the wavelength of electromagnetic radiation or light is connected to how much energy it has light with a longer wavelength like a radio wave has less energy while light with a shorter wavelength like galleries has m

What is infrared LED ? various colors of infrared ? what infrared can do to our body?

What is Infrared led? An IR LED (infrared light emitting diode) is a solid state lighting (SSL) device that emits light in the infrared range of the electromagnetic radiation spectrum. IR LEDs allow for cheap, efficient production of infrared light, which is electromagnetic radiation in the 700 nm ,850nm,940nm to 1mm range. IR LEDs are useful in a number of types of electronics, including many types of remote controls for televisions and other electronics. Used with infrared cameras, IR LEDs can act like a spot light while remaining invisible to the naked eye . Various colors of infrared? Infrared radiation extends from the nominal  red  edge of the  visible spectrum  at 700  nanometers  (nm) to 1  millimeter  (mm). This range of wavelengths corresponds to a  frequency  range of approximately 430  THz  down to 300  GHz . Below infrared is the microwave portion of the  electromagnetic spectrum . Abbreviation Wavelength Frequency IR-A 700 nm – 1400 nm (0.7 μm – 1.4 μm) 215
