To understand the properties of LED light sources, we should know some basic concepts

The color temperature color temperature

characterized by light color. It is reported in degrees Kelvin (K) and expresses absolutely black body temperature at which the body emits light with a given coloring. In practice, we distinguish several categories that characterize the color of the light source - Warm White (about 3000 K), neutral white (about 4 000-4 500 K) and Daylight (above 5500 K).

in our E-shopu use a light color - WW = warm white (cca 3 000 K) W = white (over 5 500 K).

Color temperature measured in Kelvin

Teplotabarev

  • 1200 - 1500 K: candle
  • 2500 - 3200 K: classic light bulb
  • 2700 - 3300 K: warm white
  • 3300 - 5300 K: neutral white
  • 5300 - 7000 K: white
  • 7000 - 10000 K: cool white

 

The amount of light Luminous flux

luminous flux or energy radiation in the visible range, which is able LED light source radiate into space, measured in lumens (lm). If we measure the amount of luminous flux at a certain spatial angle (ie, in a certain direction), then we are talking about intensity, which is measured in candelách (cd).

15 119 125 136
25 217 229 249
40 410 432 470
60 702 674 806
75 920 970 1055
100 1326 1398 1521
150 2137 2253 2452
200 3009 3172 3452

 

Power Consumed elec. energy

light source is measured in watts (W). It's a statement that you most often choose a light source. Another important point for the selection LED light source is the value of luminous flux (lm) or intensity (Cd), which should be indicated on the packaging. Luminous flux is usually given for lamp (which lights up the area) and mainly in luminosity reflector and light source means. source that emits a certain angle.

 

Performance Luminous efficacy

We generated expresses the amount of luminous flux (lm) at 1 W power supply power to the light source (lm/1W).
In practice, we calculate the power density according to the formula:


vzor

where ϕ the luminous flux (lm) and P is power (W).
sample:
Specific power 60W bulb = 710 lumens (this information is placed on the round light bulbs) / 60 W = 11,83 (lm / W)
Specific power 4.5 W LED light source = 215 lumens / 4,5 W = 47,78 (lm / W)

>>the higher the resulting value, the greater luminous efficacy.
