How does the lumen in the LED crusher represent and what does it mean
Title: LED 
For the last few years, come to the organization for clarification on a daily basis and publicize the premises of this exchange smoothly and painlessly. Today, no one and hate anyone with LED lamps.
Containment: 1. What e Lumen 2. Parameters that will determine the indicator for the light flow and the calculation is not ready 3. Comparative characteristics for a lamp with a pressurized button and a LED lamp
Shops sell LEDs and fluorescent bodies, but cupping continues to predict "power" as a main indicator for lighting sources. Forecast manufacturers, analyzing it, calculate the capacity for wrapping LED products, as it may mean. Do you try to concentrate everything at the top, and how can you determine the correspondence between the types of devices you have?
Better for nothing on illumination, some LED source for light production, e radiation, is emitted in the lumen. What does lumen mean in LED lamp, we will analyze it in the article.
What e Lumen
The concept of luminosity was taken from the international measuring system in the middle of the twentieth century.
Change the amount to be measured, the total lightness, removed from the source. The parameter is directly related to the concept of luxury, but there is a difference between them.
Therefore, if a lamp emitting 100 Lm, illuminating 1 m2 of surface, then the flow is equal to 100 Lx, which is lower than it. Ako shshata krushka shine in a flock with an area of 10 m2, clarification is still much lower. It is important that you know what the calculations are and the trebva will pick up the foreseeing of the goal of the light stream of all the saplings.
It is disassembled on the product only from the predominance of LED devices, pre-lamps with a pressurized button and fluorescent devices that shine in all the lights. In the diode illuminator of the body, the illuminator is close to 120 or 180 degrees. From the fence or outer bream, they get bream from any width.

Conclusion: the stream of light is flowing from the soil and crawling into the right line of the sap, increasing the concentration of it.
Manufacturers actively use this function when developing on LED lamps, installing instead of halogen and xenon, d2s lamps, devices in the farovet for cars. Those sa on - evtini from xenon, on - slightly natovarvat electric cars on the motorist from halogenite and do not step back in relation to nivoto on illumination.
Time the diodes from use for production and crushed the 20 W lamps in the page light and 55 W in the car headlight.
Parameters that will determine the indicator for the light flow and the calculation is not ready
A little bit of indicator for a light stream of sa important for a human perception:
- Quantity for everything, removed from the source to light.
- Length on vlnata. How much the perception of brightness on light depends on the tov. Ilchvaneto in the middle, green is often on the spectrum, brightly from blue or dark areas for increased power on the lamp.
- The color temperature is measured in Kelvin and the temperature is indicated on the packaging and on the product data sheet. The picture shows a rock at a color temperature and colors at a bright light.
Zabelezhka! Heat up the tone of all the colors from the choveshkoto eye kato, a little bright from the color jelly.Once you buy the "fuel" of the lamp, send a little margin to the sap by increasing the power, and for that you will create comfortable conditions in the flock.

Kolko lumen in 1 W LED mug
Namiraneto for a true answer to a question is not unfortunate. It is a fact that the manufacturers calculate the power and light flux for the LEDs, and not for the caps. Indeed, the values may be measured by the very special device. Struva si and ce concentrate on the top average indicators.
Somewhat, sometime it consumes 1 W power, LED light 90–100 lm. Take a sample in the state and “dadat” 130-140 lm from one watt.
Under laboratory conditions, it is possible to obtain LEDs producing 220 lm / W, but the devices do not produce in an industrial scale at a higher price.
The LED driver is upgraded to paint efficiency, which paints the ratio to the light flow of the power from 5-10%. It is important that you give it foreseen at the time of selection and purchased at the source for light.

For consumers who are not looking for and studying characteristics on electrical wares and distorting calculations, there are a lot of resources on the Internet with calculators. Sufficient and replace, provide data (lumeni) from the manufacturer and select the type of lighting body, and obtain the necessary indicator for power.
Method for calculating the illuminance per room
It is a simple technique to calculate the needs of a good lighting body.
Calculations are twisted into two stages:
- Calculating the need for an intensity of light flow.
- Determining on a broy on a lamp, they are able to achieve the necessary clarification.
The formula for approximately per nivoto per luminosity, Lm.
Light flow = standard indicator for luminosity in lux (given in the table) * area per room in m2 * coefficient per height per tavana.
Table 1. Standards for illuminance
For tavani up to 2.7 m, coefficient 1 is applied, with a height per room from 2.7 to 3 m - coefficient 1.2, from 3 to 3.5 m - 1.5.
Calculation example. In the children's flock, the standard for illumination is set at 200 Lx. Flock area 12 m2 Vysochina 3.1 m - applied coefficient 1.2.
Multipliers 200 * 12 * 1.2, get the necessary light output from 2880 lm.
Poznavayki luminous indicator, those will choose devices that are capable of mastering. A single 25-30 W LED lamp or three 10-watt sources is enough for a dadenate flock.
Comparative characteristics for a lamp with a pressurized button and a LED lamp
Used for energy from various types of crush
When comparing the technical characteristics of the parameters, the parameters say they are crawling on the diode device.

The price of LED lamps is extremely low and cost-effective crawl from the use of it is ruled by devices for popular environments.

LED lamps are from proven manufacturers and have an undeniable prestige that they use every day and in production.Those sa izdzhlivi, ekonomichni and barzo will make them cry. Possibility, yes, choose every nuance to shine, direct it while standing in the flock is convenient and safe.
