As we all know, the incandescent lamp has a subtle flicker, when a person is in the room for a long time, it will have a negative impact on his vision. For people who are used to it, this flickering may be completely invisible, but for people with sensitive eyeball nerve endings, it will cause inconvenience and irritability. Therefore, LED lamps without such defects have been invented. They also have no harmful radiation such as ultraviolet and infrared. In fact, this is their main operating principle. Due to this radiation, the eyes will feel overworked, and therefore, a person may become blind after a period of time. Among them, energy saving is an important factor. LED lamps are much more economical than incandescent lamps, but the price of diode lamps is much higher. Therefore, in this article we will tell you how to choose the LED pin and analyze the problem:Are LED bulbs energy efficient?. . .
Pros and cons
As mentioned above, the main advantage of LED lights is energy saving, and in our country, saving electricity is the key to a comfortable life. Moreover, the design of these lamps is very elegant, which brings a certain charm and attraction to a room or room. In European countries, incandescent lamps are no longer used. In addition, there are even special legislative plans to eradicate the production of such lamps and their use in daily life.
It is worth noting that the frequency of "burning" of ordinary lamps is very high. Poor filament hair quality causes the bulb itself to fail and can only be replaced. LED lamps, or energy-saving lamps commonly known as energy-saving lamps, are rarely unusable, and their life expectancy is 1 to 5 years, sometimes even longer. Such a long life lies in their structure.
LED lighting devices are made of a variety of materials and give them different types of shapes. In the market, you can find bulbs suitable for various tastes and colors, and you can also choose bulbs suitable for your interior decoration, because there are lamps for general (main) lighting and decoration. Don't forget factors such as very high light output. For example, a 15 W lamp provides light for all 120 lights with minimal voltage consumption.
The disadvantages of these lamps are high cost, and the lamp cannot be changed from one place to another frequently, otherwise its service life will be greatly shortened.
how to choose
When choosing which lamp to buy, we recommend that you pay attention to two factors: manufacturer and characteristics. The large number of manufacturers allows you to accurately choose the lamp that suits you best. Production takes place in all countries in the world, but China is still the main supplier.
However, the area that needs attention is the product characteristics. which is:
- Limiting characteristics, namely power, incandescent lamp temperature, angle, brightness, etc. The characteristics are directly proportional to the manufacturer. In other words, the fault of the butler is usually related to the incorrectly provided information about the characteristics of the device;
- The appearance of the lighting device itself. This is worthy of attention, because only you know how this or that lamp fits your interior. The lamp may not be used due to inconsistency with the purpose;
- Check the properties of the power supply and the microcircuit. It is important to consider that not every housekeeper will work at low temperatures, for example, working outdoors in winter. In addition, the voltage drop in the power grid is also considered, as this will affect the durability of the entire luminaire. Therefore, please read the safety precautions and instructions before use;
- Expensive LED lights usually have diodes, which can be replaced in the event of a failure. This is also worth paying attention to, because usually these lamps have a long service life, but the possibility of repair is greatly increased, because the purchase of replaceable diodes is cheaper than the lamp itself;
- In addition to the luminaire quality indicators, the box should also contain detailed documents, which contain all the information about the characteristics and instructions for use. This is what every self-respecting manufacturer does.
Don't forget fakes, because they have a place in the market. It is impossible to check with the naked eye, but there are specialized laboratories that can check whether your equipment is fake. Although it is worth noting that fakes are sometimes not inferior to genuine in quality.
Energy saving calculation
As mentioned above, the main advantage of LED bulbs is energy saving. This saving lies in that under low power consumption, a large amount of light radiation is generated per unit.
Below we provide you with some comparison tables of lamps and LEDs. The main characteristic of a lamp may be its light emission, which is measured in lumens (Lm).
so:
| Incandescent lamp power (W) | Fluorescent lamp, power (W) | LED light 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 |
| one 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 considering that all "housekeepers" emit narrowly focused light energy. On the box, manufacturers often indicate this parameter, so careful consideration should be given to the selection of lighting equipment to avoid discomfort. Another parameter is the color heat transfer, or more simply, the color of the light. Incandescent lamps have only one hue, yellow, while LED lamps have multiple colors and hues. This is also done to facilitate the lighting of the place, depending on the needs of the buyer.
in conclusion
So, in summary, we can conclude that among all the lighting equipment on the market, it is most profitable to choose LED lights to save electricity bills and thus save your money.
We hope this article will give you an answer to the question about whether LED lights are energy-efficient, it is true.
