Now energy-saving lamps are popular in our homes, which are common energy-saving lamps, but with the improvement of science and technology, more and more homes are using LED work lights, so what’s the difference between led work lights and energy-saving lamps?
First of all, from the perspective of the service life of lamps, the service life of ordinary energy-saving lamps can reach 10,000 hours, while led is different from ordinary energy-saving lamps due to the way of emitting light. Therefore, the service life of LED work light is longer, up to 100,000 hours. As the service time increases, the brightness of ordinary energy-saving lamps will get darker and dimmer.
Finally, it breaks down, and although led work light also have such a situation, their service life is much longer than that of ordinary energy-saving lamps.
We can analyze these two kinds of lamps from the perspective of environmental protection. Ordinary energy-saving lamps contain mercury and other harmful ingredients, but led work light may also have some harmful ingredients.But without mercury and so on, it can be recycled.
Compared with ordinary energy-saving lamps, LED work lights are inferior in terms of heat dissipation. Energy-saving lamps are not very good in heat dissipation. And the heat dissipation of Led work light is really good, which is the shortcoming of LED lamps, but now the manufacturers are overcoming led such defects, and the development of radiator is also in progress.
Technical comparison: the main luminescent material of energy-saving lamps is still tungsten filament. LED work lights are formed by series or parallel connection of LED beads. These LED beads are composed of light-emitting diodes. Different light sources, different principles.
Energy – saving lamp generally refers to: is the three primary color fluorescent lamp.It is a kind of device that uses mercury vapor discharge to produce ultraviolet ray, ultraviolet ray reirradiate the rare earth phosphor on the glass wall, the light source illuminated by the phosphor.This lamp needs a high voltage to work.
The LED work light is a semiconductor diode. When a forward voltage is applied to the LED, it is injected from the P region to the hole in the N region and from the N region to the electron in the P region. Within a few microns near the PN junction, it is recombined with the electron in the N region and the hole in the P region respectively to produce spontaneous emission of different colors of light.
Different colors of light can be produced in different semiconductor materials.The current white light uses blue light from blue leds to reactivate yellow phosphors, Mixed into white light for illumination.Red, green and blue can also be mixed into white,The LED can work under low voltage DIRECT current.
Energy-saving lamp is called compact fluorescent lamp again (foreign abbreviation CFL lamp) have light efficiency is tall (it is 5 times of common bulb), energy-saving effect is apparent, life is long (it is 8 times of common bulb), volume is small, use convenient wait for an advantage.It works on the same basic principle as a fluorescent lamp.
In addition to white (cold light) energy-saving lamps now have ***(warm light).On average, an CFL-powered lamp uses 80 percent less energy than an incandescent, has an average life span of eight times longer, and emits only 20 percent more heat for the same wattage.In the non-strict case, a 5-watt CFLLAMP can be thought of as a 25-watt incandescent, a 7-watt CFLlamp is about 40-watt, and a 9-watt is about 60-watt.
LED work lights
An LED work Light Emitting Diode is a solid state semiconductor device that converts electricity directly into Light.The heart of an LED is a semiconductor chip with one end attached to a scaffold and a negative end,The other end is connected to the positive end of the power supply so that the entire wafer is encapsulated in epoxy resin.
A semiconductor chip consists of three parts: a P-type semiconductor, in which holes dominate, and an N-type semiconductor,On this side it’s mostly electrons, and in between it’s usually a quantum well of one to five cycles.When an electric current is applied to the chip through a wire, the electrons and holes are pushed into a quantum well, in which the electrons combine with the holes,It then emits energy in the form of photons, which is how leds glow.
LED work lamps have many advantages, such as small size, low power consumption, long life, non-toxic and environmental protection, etc. LED lamps have gradually developed from outdoor decoration, engineering lighting to household lighting.
