Every person, having come to the store, wants to purchase high-quality equipment that will serve for 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 with other types of fixtures. To resolve this issue, it is necessary to study the technical characteristics of the parts. Each of them can be found on the packaging. Let's take a closer look at these characteristics.
Plinth
Today, many LED lamps are produced in different designs.
All types of LED lamps have different designations that show 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 more power, the brighter 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 from 3 to 25 V. For a living room, 12 V LED lamps are optimal.
Power supply for the device
The power supply is alternating and direct current. If you use a constant, then 12 volt LED lamps are best suited for these purposes. However, a prerequisite for their functioning is the use of special drivers. It is their circuits that drive the lamp. The drivers also serve to connect to a household AC outlet.
Important! Before purchasing a lamp, you need to find out what kind of current will be used - AC or DC.
If the selection is incorrect, the LED will not work or will burn out when first turned on. If a driver is installed in the LED lamp, then it easily tolerates power surges. At the same time, it will work in the same mode.
Light flux
This is the most significant technical indicator. The brightness of light emission and efficiency depends on it. The unit of measurement is lumens. It shows the ratio of the radiation power to the voltage used, thereby showing its effectiveness. For example, for conventional products, this indicator is 15 Lm / W, and for LED products - 90 Lm / W. It can be concluded that each watt of a diode lamp emits ten times moreluminous flux than conventional products. How to choose an LED lamp for this indicator? When buying, you should take into account this pattern. With a power of 40 W, the flux is 400 Lm, 60 W - 600 Lm, etc.
Emitting color
This indicator distinguishes LEDs from incandescent lamps. It can be selected in a fairly wide range, unlike incandescent lamps, where only yellow color prevails. 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, yellow color means that the temperature of the radiated stream is 2700 K. Daylight is characterized by 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 emission? It must be selected based on personal preferences. That is, it all depends on which object will be shown.
Brightness adjustment
Another feature of LED lamps is dimming. To do this, you need to purchase a special device. This is a dimmer that controls the LED with pulses. The smaller they are, the lower the brightness of the lamp, and vice versa. In this case, such switching is not visible, since the frequency is more than 200 kHz. Therefore, human eyes do not notice this flicker. However, not all 12 Volt LED lamps are tuned. This is not possible due to the built-in driver that tunes the product to a specific frequency.
Flow direction
When using a diode lamp, please note that the light is directed only in one direction. This problem goes unnoticed if you use products for a small lamp. Another thing is if it is necessary to illuminate a sufficiently large area of \u200b\u200bthe room.
For these purposes, a diffuser is installed on the devices.
Working range
The LED lamp is capable of operating at air temperatures from -45ºС to +45ºС. This allows them to be used in certain temperature conditions.
Other features
Besides light, the LED emits a small amount of heat that 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 fail.
LED lamp with battery
This product is powered by a normal household electrical outlet with a voltage of 220 volts. As a rule, these lamps are equipped with 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 a day. Many users find the rechargeable LED lamp to be a useful device.
Now you do not need to look for a switch at night. Just enoughpress the button on the remote control. The cost of such a model is about 600 rubles.
Philips LED bulbs
The most common model of this type of lamp is "Philips". When turned on, they emit a soft warm light that makes any room feel cozy. In addition, they have a long service life, as well as significantly save energy. Its significant advantage is the regulation of lighting. The emitted light helps to better see the decorative elements of the room and create a cozy homely atmosphere.
Among the many types, it is worth choosing a product such as a candle lamp. It is she who fits perfectly into any interior. The cost of such products is 400 rubles. Many users are satisfied that they use Philips LED lamps. This is quality equipment that is available at low prices.
Conclusion
LED products are high-quality devices that serve to illuminate the room and other interior elements. Compared to incandescent lamps, they have many advantages. Of the most important advantages, it is worth highlighting the brightness control, operating range and luminous flux. As for the question of how to choose an LED lamp, 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.
