For over a hundred years, people have been using incandescent lamps to illuminate their workplaces, houses and industrial premises. Over the past few decades, alternative lighting devices have gained widespread development. Incandescent filaments were replaced by fluorescent lamps, which today are replaced by LED products.
New lighting devices
Reducing the cost of semiconductor LEDs made it possible to use them much wider compared to conventional ones. Not only as part of the equipment for various purposes, but also in the role of replacing signal lamps or decoration, as well as in the role of a full replacement of lighting devices. They are characterized by a wider range of characteristics, ranging from consumption, power of the luminous flux of dimensions and ending with the color of the radiation.
Technical Specifications Reviews
If you are interested in LED lamps "Navigator", then you should familiarize yourself with their technical characteristics in more detail, only in this way you can decide on the model. Having visited the store, you can see that the characteristics are presented on the packaging or on the device itself in the form of markings. Thus, you can find out which base is in front of you and what kind of case the product has. The marking indicates this: E14, E27, G5, G13, GU4, GU5 * 3. The power consumption of these products can vary from 3 to 20 watts. The supply voltage is from 12 V DC to 220 AC. Consumers have the opportunity to choose the heat of the emitted light, which varies from 2700 to 6700 K. Customers really like that they have the ability to adjust the brightness, as well as choose options for the distribution of light. The lamp LED navigator E27 is the product that has the most popular type of cap, as for most incandescent lamps used in household appliances. If we are talking about nightlights and lampshades, then there is most often found the size of the base E14. An even smaller base can be found in the microwave or in the refrigerator. According to consumers, on sale you can find the largest base E40, which is designed for large industrial premises and street lighting.
Power Reviews
If you are interested in LED Navigator lamps for the home, then you should be aware of the power consumption. It plays a significant role in calculating the total lighting consumption of a building or individual room. You can choose from a wide range of products products whose power consumption varies from 3 to 25 watts. Consumers emphasize that it is not possible to determine unambiguously the degree of brightness or the power of a stream by the consumed power .
Current Source Reviews
Navigator LED lamps can work from a direct current in a network with a voltage of 12 V. Special drivers and circuits are used to operate them in order to bring the external power supply voltage to the desired one for the element itself. Through the drivers, according to customers, it is possible to connect to an alternating rated voltage of 220 volts in a household electrical network. Among other things, you can prefer a design designed for AC constant voltage from 12 to 24 V. Experienced consumers are advised to specify in advance what voltage is supposed to be used for power, which will allow you to choose the appropriate model. LED bulbs “Navigator” in the best case simply will not work if you make the wrong choice. In the worst case, one should expect that the product will burn out when an excessively high voltage is applied. Choosing Navigator LED lamps, which are equipped with drivers, you will get products that will be able to more easily tolerate the jumps that occur on the network. If an incandescent lamp dims with a decrease in voltage, and lights up brighter with an increase, then the LED elements in a wide range will shine equally effectively.
Luminous flux reviews
Choosing LED lamps for the Navigator home, reviews of which you can read in the article, it is worth paying attention to the light emission power, which is the most significant parameter. This indicator is measured in Lm or Lm / W. The last parameter will determine the ratio of radiation power to power consumed. This will allow you to understand profitability. If we compare with an incandescent lamp, which is often done by consumers, then its efficiency is from 10 to 15 Lm / W. As for LED products, this parameter varies from 70 to 90. This indicates that for each watt the lamp will give out 10 times more power of the light flux.
Color Temperature Reviews
LED bulbs "Navigator", reviews of which are often only the most positive, are also characterized by color temperature, which is one of the main differences between these elements and traditional incandescent lamps, which is why consumers often choose these products. It can be selected in a wide range, which differs from the yellowish glow characteristic of the filament. You can decide what color shade you need on the color temperature scale, it is built on the basis of the color glow of the metal when it is in a red-hot state. Choosing LED lamps "Navigator", reviews of which will help you make the right choice, you should choose the color of the radiation, taking into account your own preferences or the interior decoration of the room. Thus, the temperature of the warm yellow glow of the metal will correspond to a temperature equivalent to 2700 degrees Kelvin. If there is a need for daytime white color lighting, then you should choose a limit from 4500 to 6000 degrees Kelvin. At the lower boundary, white light will give off a yellow tint. A cool bluish color will correspond to a temperature that is above 6500 degrees Kelvin.
Brightness Adjustment Reviews
Lamp "Navigator" LED 7W can be adjusted in brightness. It is this factor, according to users, that these products compare favorably with economical fluorescent lamps. In order to control the LED was possible, you should use a device called a dimmer. He is able to form nutrition, which appears in the form of impulses. The lower the frequency, the dimmer the diode will burn. When a 10-watt LED Navigator is used, the user will not see the blinking at all, he will not feel any discomfort, as the frequency is 200 - 300 kHz. This is true, since the human eye is able to perceive the blinking frequency only within 200 Hz. It should be taken into account only that moment that not all LED lamps of the mentioned manufacturer have the ability to adjust by brightness. The built-in driver will limit this feature if it is tuned to a specific frequency or line power. If you decide to purchase a lamp with the ability to regulate, then you should choose a dimmer product, find out that in front of you is such a lamp, you can read the instructions.
Reviews on the temperature of the working environment
NLL Navigator LED bulbs can operate over a wider range than traditional fluorescent tubes. For the most part, they are able to work at ambient temperatures ranging from +5 to +45 degrees. As for LED products, they can be used in the range from -40 to +40 degrees. This allows you to operate these lamps in those conditions where you can use only gas discharge or sodium lamps. This parameter is to the liking of the modern buyer, which is why the Navigator LED lamps have become so widespread.
Additional Feature Reviews
The scheme of the LED lamp "Navigator" will allow you to understand that the LED during operation also generates heat, in addition to light. It is much less intense compared to what an incandescent lamp emits, but it is still noticeable. The main problem, according to users, is that heat is distributed in the opposite direction, rushing towards the diode substrate. If overheating occurs, the semiconductor may lose some characteristics and fail.
