As everyone knows, incandescent lamps have a fine flicker, which when a person is in the room for a long time, negatively affects his vision. For those accustomed, this flicker may be completely invisible, but for people with sensitive nerve endings in the eyeball, it can cause discomfort and also lead to irritability. That is why LED lamps have been invented that do not have such a defect. They also do not have harmful radiation such as ultraviolet and infrared light. In fact, this is their basic principle of operation. Due to this type of radiation, the eyes feel overwhelmed, as a result of which a person may lose his sight after some time. Among other things, energy saving is an important factor. The LED lamp is much more economical than incandescent lamps, but the price of the LED lamp is much higher. Therefore, in this article we will tell you how to choose an LED foot and analyze the issue:Do LED bulbs save energy?. . .
Advantages and disadvantages
As mentioned above, the main advantage of LED lamps is energy savings, and in our country saving electricity is the key to a comfortable life. In addition, the design of these lighting fixtures is very elegant, which gives the room or the room a certain charm and attractiveness. In European countries, incandescent lamps are no longer used. In addition, there are even special legislative programs to eradicate the production of such lamps and their use in everyday life.
It is worth noting that ordinary lamps "burn" very often. Poor thread quality leads to damage to the bulb itself and can only be replaced. LED lamps, or as they are popularly called energy-saving lamps, rarely become unusable and their lifespan is from 1 to 5 years, and sometimes longer. Such a long life lies in their structure.
LED lighting devices are made of different materials and also give them different types of shape. On the market you can find them for every taste and color, as well as choose the light bulb that suits your interior, as there are lamps for general (basic) lighting and decoration. Do not forget about such a factor as very high light output. For example, a 15 W lamp provides light for all 120, while voltage consumption is minimal.
The disadvantage of these lamps is their price, as well as the fact that the lamps can not be changed often from one place to another, otherwise their service life will be significantly reduced.
How to choose
When choosing which luminaire to buy, we advise you to pay attention to two factors: manufacturer and characteristics. The number of manufacturers is huge, which allows you to choose exactly the lamp that suits you best. Production takes place in all countries of the world, but China is still the main supplier.
But the aspect to focus on is the characteristics of the product. namely:
- Limiting characteristics, ie power, incandescent temperature, angles, brightness, etc. The characteristics are directly proportional to the manufacturer. That is, often the failures of the hosts may be related to incorrectly provided information about the characteristics of the device;
- The device of the lighting device itself, its appearance. This is worth paying attention to, because only you know how this or that lamp will fit into your interior. The lamp may become unusable due to the fact that it does not meet its purpose;
- Check the properties of the power supply and chips. It is important to keep in mind that not every housekeeper will work at low temperatures, for example outside in winter. The voltage drop in the electrical network is also taken into account, as it affects the durability of the luminaire as a whole. Therefore, before use, read the precautions and instructions for use;
- Expensive LED lamps most often have diodes that can be replaced in case of failure. This is also worth paying attention to, as the service life of these lamps is usually high, but due to the possibility of repair increases significantly, as it is cheaper to buy replaceable diodes than the lamp itself;
- In addition to the luminaire quality indicator, the box must contain a detailed file with all the information about the characteristics and instructions for use. This makes every self-respecting manufacturer.
Don't forget about counterfeits as they have a place to be on the market. It is impossible to check this by eye, but there are special laboratories where you can check your equipment for counterfeit. Although it is worth noting that counterfeits are sometimes not inferior in quality to the original.
Calculation of energy savings
As mentioned above, the main advantage of LED bulbs is energy savings. This saving lies in the fact that low energy consumption generates a large amount of light radiation per unit.
Below we give you a comparison table of some lamps, unlike LED. Perhaps the main characteristic of the lamp is its light emission, which is measured in lumens (Lm).
Thus:
| Incandescent lamp power (W) | Fluorescent lamp, power (W) | LED lamp power (W) | Luminous flux (lm), average |
| twenty | 5-7 | 2-3 | 250 |
| 40 | 10-13 | 4-5 | 400 |
| 60 | 15-16 | 8-10 | 700 |
| 75 | 18-20 | 10-12 | 900 |
| hundred | 25-30 | 12-15 | 1200 |
| 150 | 40-50 | 18-20 | 1800 |
| 200 | 60-80 | 25-30 | 2500 |
The choice is obvious, but it is worth taking into account the fact that all "housekeepers" emit narrowly focused light energy. Manufacturers often specify this parameter on the boxes, so you should carefully consider the choice of lighting device so as not to cause discomfort. There is also such a parameter as color heat transfer or, more simply, the color of light radiation. Incandescent lamps have only one shade, yellow, LED lamp has several colors and shades. This is done for the convenience of lighting the premises, depending on the needs of the buyer.
Conclusion
So from all the above we can conclude that among all the lighting devices on the market, it is most advantageous to take an LED lamp to save electricity and money.
We hope that this article has given you an answer to the question of whether LED lamps save energy and whether it is true.
