What’s the common light supply in life?

The earliest use of electric light source is incandescent, is our usual said the electric light. It truly is according to the principle of thermal radiation is created, the tungsten filament to red hot, only a compact part with the power is converted into visible light, electrical energy consumption can mainly transformed into heat energy, the light emission efficiency is low. So incandescent lamps waste loads of power. To emit visible light tungsten to 500 DEG, with growing temperature, progressively modifications from red to orange and white. Incandescent lamp that emits light is light, however the proportion of numerous colors of light is by luminous material (W) and temperature, the ratio imbalance will result in partial color colour, so in incandescent light the colour of objects not accurate (that is, the color of not higher), which is in purchasing malls as well as other public areas without the usage of incandescent lighting is amongst the reasons as a way to enhance the efficiency of light.

In the early 1940s invented the fluorescent lamp, because of its color close for the sunlight also called daylight lamp. A filament is arranged on both ends of a fluorescent lamp tube, the tube is filled with mercury vapor thin, on the inner wall in the lamp tube is coated with fluorescent powder, the gas in between the two filament conductive emit ultraviolet and fluorescent powder to emit visible light soft. Compared with incandescent lamps, fluorescent lighting efficiency have improved considerably, saves the electrical power is amongst the most important elements on the fluorescent lamp ballast, which utilizes the principle of induction, the fluorescent lamp is started to provide instantaneous high pressure; when the lamp works typically, step-down present limiting to make sure fluorescent lights inside the low-pressure environment for stable perform and prolong the service life in the fluorescent lamp. But the ballast energy consumption, weight, size, and noise.Fluorescent lamp in the AC voltage of 50Hz, with all the voltage and current adjustments, the luminous of fluorescent lamp also has a periodic modify of light and shade, which can generate a flicker. This sort of flicker isn’t quick to become perceived, but it is simple to perform beneath the sun lamp, as well as the eye is simple to fatigue, and it’s going to impact the development with the technologies.

Energy saving lamp will be the core portion with the lamp and electronic ballast. Tube coated with trichromatic fluorescent powder, trichromatic fluorescent powder is a higher efficient fluorescent powder, can emit brighter light, than the regular fluorescent lamp closer for the sun light, the fluorescence powder can strengthen the luminous efficiency of the electronic ballast works: by the rectifier circuit of 50Hz AC into DC rectifier, by higher frequency producing circuit for converting the direct existing into about 30kHz high frequency alternating current and just after LC circuit of lamp energy provide. The LC circuit of energy-saving lamps in the use of self inductance phenomenon. Electronic ballast by electronic components, low power consumption, light weight, can be conveniently installed inside the lamp, drastically reducing the lamp of the weight, the far more prominent feature is after increasing the operating frequency and not feel the light flicker that is straightforward to begin up, no noise and save electric power. A 9W power saving lamp is equivalent towards the light impact of 60W incandescent lamp. In addition, the lamp can be made into many shapes, can play a decorative effect, so energy-saving lamps in to the interior decoration of fashion lamps. Because of the higher efficiency on the electronic energy saving lamp, no pollution, no noise, no flicker, is called the “green light source”. It’s going to come to be the dwelling with the most important electric light supply.
