LED stands for light emitting diode. A diode is a device that allows electric current to flow in one direction but blocks it from flowing in the other. A good way to think of it is as a water valve for electricity. What separates an LED from just a regular diode is its ability to emit light when turned on. As you may already know the type of colour depends on the wavelength of light, with the red side of the spectrum being a longer wavelength and the violet side being shorter. An LED utilizes different compositions of materials to produce different wavelengths of light. This allows colours of impeccable purity and brilliance to be emitted, unlike incandescent bulbs which typically use a colour filter to produce the different hues. The actual process behind an LED light is far more complex than this as it involves both physics and chemistry to understand them fully. If you're looking for a more detailed explanation the team at London Lighting Hire is very knowledgeable in this department along with various other types of lighting so they'll surely have the answers you're looking for.
LED light angle is divided into effective angle and the actual light angle. The luminous intensity value is half the direction of the axial intensity and the direction of the light-emitting axial (normal) is the effective angle. Half of the half angle of the angle (or half power angle) is the actual light angle. In the axial strength of half the angle because the light is too weak in practical applications do not count the effective angle. (The picture below shows the side view of the piranhas particles, the angle between the solid line and the dashed line is not included in the effective angle)
LED will certainly become the fourth generation of lighting, its development momentum more and more fierce, the main advantages are: energy saving, long life, no flicker does not hurt the eyes, do not attract mosquitoes. High-power LED lighting as long as the thermal design is good enough, 3-5 million hours of life is no problem (life is defined as: LED because it is a semiconductor component, the chip affected by the temperature will produce light failure, when the LED luminous flux because Light attenuation of less than 30% of the initial luminous flux, the basic LED lighting is no lighting significance, that is, life summary, although this time the LED lights can still light it, but the brightness has dropped significantly, so LED lighting is very Important is important).
