Technical progress has given the world energy-saving technologies, which is reflected, in particular, and in energy-saving light bulbs. In addition to the financial savings of the consumers of electricity, these developments help the country save energy, which is very good for the ecology of the planet.
Energy saving lamp is available in two versions: led and fluorescent. Each of them has its advantages and disadvantages.
How to choose economical and environmentally friendly lamp, which would save money on lighting, but does not harm the health? The answers in this article.
Almost all contemporary lighting has a high luminous efficiency and designed to conserve the finances of the people who will use it. But saving methods thus differ. Fluorescent lamps are gas-discharge lamps low pressure, which contain elements of mercury. Led lighting is no mercury that makes them environmentally friendly bole.
Appearance fluorescent lamp of compact type is a narrow flask, curved shape. This structural solution allows to place it even in miniature lamps. What CFLs have replaced the familiar, but outdated incandescent lamps that have an increased electric "appetite".
Fluorescent lamp used in domestic lighting and in some specific. Sealed inside the CFL tube is an inert gas, neon or argon and mercury vapor. In addition, the inner wall of the case is covered with a phosphor layer, which causes the gas to glow when voltage is applied.
Manufacturers have created several types of fluorescent lamps, depending on exactly where you will use the lighting device from the bathrooms to the domestic and industrial luminaires with different diameter of the cap.
All the above types of lamps have a guaranteed job from 3 000 to 15 000 hours and have to either open up, or have the diffusing device. The color of the radiation CFLs also vary from warm to cold shades.
The advantages of fluorescent lamps:
• Reduce energy costs by up to 80% compared with incandescent lamps with the same luminous flux;
• Increased life expectancy of up to 15,000 hours, which is 14 times higher lifetime of the bulb;
• Less heat radiation, which allows the use of CFLs in chandelier of unusual design, made of substandard materials;
• Uniformity of distribution of light is higher at a more benign impact on the human eye;
• Variety of color temperatures.
The main disadvantage of CCL is the use of mercury, which belongs to the first class of hazard scale of toxic substances. The situation is aggravated by the fact that mercury is in a gaseous state. And if the damage to the walls of the lamp mercury gas will evaporate instantly in the air, filling the room. When injected into the lungs of man mercury been out of the body, accumulate in it and moving all the internal organs.
In led bulbs, this disadvantage is absent, which makes led lamps led lamps are the most eco-friendly and safe lighting option for today. They are used both in household appliances and in the production: the lighting of apartments and offices, interior lighting, exterior architectural lighting, street lighting, explosion proof lights and led appliances.
This became possible due to the variability of performance of the lamp cap, so it can be used in any lighting appliance, despite the complexity of their design. Also depending on where you will use the led lamp, it is released with a lens or without.
For example, for a table lamp would be a regular version without a lens, but the lamp in the chandelier definitely need a diffuser, as the light beam is only 60 degrees, which is sufficiently narrow to illuminate the whole room.
The properties of the emitted luminous flux of the lamp bulbs are classified as General purpose, directional light and linear led lamp with swivel base.
Advantages of led lamps:
• Increased service life up to 100,000 hours;
• Increased energy, allowing you to consume 10 times less energy compared to traditional incandescent lamps;
• Environment-friendly and no harm to human health.
Led lamps have all the advantages of fluorescent. The only downside of lamps of this type is their cost, which is much higher than the cost of fluorescent lighting units.
P. S. And remember, only by changing their consumption — together we change the world! ©
