How to choose an LED lamp? Characteristics, types and manufacturers

Each person, having come to the store, wants to buy high-quality equipment that will serve a long time. Therefore, the question arises: how to choose an LED lamp? As a rule, people rely on reviews on the Internet. But not always these lamps are in the store. They can be replaced by other types of fixtures. To solve this problem, it is necessary to study the technical characteristics of the parts. Each of them can be found on the package. Let us consider these characteristics in detail.

Plinth

To date, many LED lamps are available in different designs.

All types of LED lamps have different designations, which indicate in which area they can be used. For example, the designation E40 indicates that it is used to illuminate large rooms or streets.

Power

It plays an important role in lighting the room. The higher the power, the lighter the room will be. However, this indicator is affected by the degree of brightness of the light flux. All devices of this type are produced with a power of 3 to 25 V. For a living room, the optimal LED lamps are 12 V.

Current source for the device

As a supply serves as alternating and direct current. If you use a constant, then for these purposes, the best LED lamps are 12 volts. However, the mandatory condition for their operation is the use of special drivers. It is their schemes that put the lamps into operation. Drivers also serve to connect to an AC household.

Important! Before buying a lamp, you need to find out which current will be used - alternating or permanent.

If the selection is incorrect, the LED will not work or burn out the first time it is turned on. If a driver is installed in the LED lamp, it easily tolerates voltage surges. At the same time, it will work in the same mode.

Light flow

This is the most significant technical indicator. It depends on it the brightness of light and efficiency. The unit of measurement is the lumen. It shows the ratio of the radiation power to the voltage used, thereby showing its effectiveness. For example, in conventional products this figure is 15 Lm / W, and for LED products it is 90 Lm / W. It can be concluded that each watt of a diode lamp emits ten times more light flux than conventional products. How to choose an LED lamp for this indicator? When buying, you should take into account this pattern. At a power of 40 W, the flux is 400 lm, 60 W - 600 lm, and so on.

Radiated color

This indicator distinguishes LEDs from incandescent lamps. It can be selected in a fairly wide range, in contrast to incandescent lamps, where the predominantly yellow color. To make it easier to determine such values, a special scale was invented.

It was created by heating the metal to a certain temperature. So, the yellow color means that the temperature of the emitted stream is 2700 K. Daylighting is characterized by a white color. Here the temperature is 6000 K. Everything above this indicator has a blue tint.

How to choose an LED lamp by the color of the radiation? It must be selected based on personal preferences. That is, everything depends on which object will be demonstrated.

Brightness control

Another possibility of LED lamps is brightness adjustment. To do this, you need to purchase a special device. It is a dimmer that controls the LED with pulses. The less they are, the less will the brightness of the lamp, and vice versa. This switching is not visible, since the frequency is more than 200 kHz. Therefore, human eyes do not notice this flickering. However, not all 12 volt LED lamps are tuned. This is not possible due to the built-in driver, which adjusts the product to a specific frequency.

Flow direction

When using a diode lamp, it should be taken into account that the light is directed only to one side. This problem goes unnoticed if you use the products for a small lamp. Another thing, if you need to cover a fairly large area of the room.

For these purposes, a diffuser is installed on the devices.

Working range

The LED lamp is capable of operating at an air temperature of -45 ° C to + 45 ° C. This allows them to be used in certain temperature conditions.

Other Features

In addition to light, the LED emits a small amount of heat, which is palpable. The only negative point is that the heat does not go along with the light, but in the opposite direction, that is, to the diode. If it is significantly overheated, the device may be damaged.

LED lamp with battery

Such a product operates on a regular household electrical system with a voltage of 220 volts. As a rule, these lamps have in their complete set a special control panel. It is used to turn the light on and off. Thanks to the built-in battery, the product can work without electricity for almost 24 hours. Many users believe that the LED lamp with battery is a useful device.

Now you do not need to look for a switch at night. It is enough just to press the button on the panel. The cost of this model is about 600 rubles.

LED Light Bulbs Philips

The most common model of this type of lamp is Philips. When turned on, they emit a soft warm light, which gives any room a cosiness. In addition, they have a long service life, and also significantly save electricity. Its significant advantage is the regulation of lighting. Radiated light helps to better consider the decorative elements of the room and create a cozy home atmosphere.

Among many types it is worth choosing such a product as a candle-lamp. It is perfectly fit into any interior. The cost of such products is 400 rubles. Many users are satisfied that they use Philips LED lamps. This is a quality equipment that is available at low prices.

Conclusion

LED products are quality devices that serve to illuminate the room and other elements of the interior. In comparison with incandescent lamps, they have many advantages. Of the most important advantages, it is worth highlighting the adjustment of brightness, operating range and luminous flux. As for the question of how to choose an LED lamp, then first you need to study all the technical characteristics. Only after that you can go to the store and purchase the appropriate option.

So, we figured out how to choose the right LED lamp.
