Abstract: This article explains the advantages of Oświetlenie ledowe and common terminology and units of the lighting fixtures, if you are just entering the LED lighting industry practitioners, or the novice want to buy LED lamps, who do not want to be deceived, this article is worth reading.

 

We need to know a basic concept of LED, what is LED? LED is known as LED diodes, is able to convert electrical energy into visible light solid-state semiconductor devices. So what’s the advantage of LED lights?
Mainly in below four areas:

Pierwszy, energy-efficient
Work with low-voltage driver,ultra low power consumption (single led 0.05w). Luminous power conversion close to 98%, to compare with traditional light, LED light save 60%-80% energia, what’s more-Diody LED are installed flexible,durable and reliable.

 Sekunda, green power

Light without UV and infrared radiation, soft lighting effects, bez migotania. It is a real green lighting than any light else. It doesn’t have harmful elements such as mercury and xenon, conductive to recovery and secondary use.

Third, the long life

Seismic performance and dust-proof performance, niski pobór mocy, low required voltage and current, less heat. LED light is solid light source, epoxy resin, luminous body part is not easy loose. It does not exit filament easy to burn, or the shortcomings of thermal deposition and high light decay. It has long life up to 30,000 do 50,000 godzin, który jest 30 times than ordinary light bulb, the equivalent of uninterrupted lighting for three years.

 

Fourth, the scope of application

Oświetlenie domu, ceiling downlights, oświetlenie biurowe, residential lighting, supermarkety, stalls, shops, restauracji, hotele, bary, cafes and Western restaurants, entertainment, family night light, festive atmosphere with candles, solar lighting applications, urban lighting landscaping works and other widely used.

 

Reference to the diagram to understand professional terminology will be easier and more the image.

 

Luminous flux Ф

Jednostka: lumen (lm)

Light emission energy and people’s eyes to receive the total is the luminous flux (Ф)

Light intensity l

Jednostka: candela (cd)

 

Ogólnie, the rays are launched in different directions, and varying levels of intensity, the intensity emitted by visible light in a particular direction is called intensity (L)

 

Illuminance E

 

Jednostka: luks (lx)

 

Illuminance (mi) is the coefficient of the ratio between the luminous flux and the irradiation area.

 

1lx refers 1lm the luminous flux is evenly distributed in bright the area 1lm2 plane.

 

Units of candela / square meter [cd/m2] jednostka: cd / m

 

Jasność 

That the eye can see objects the reflected light intensity from one direction.

 

Light effect Light, efekt

Jednostka: lumen [lm / w] jednostka: the lumen [lm / w]

Luminous efficiency refers to the electrical energy into light efficiency.

 

Color temperature of the Color Temperature

 Jednostka: kelwin [k]

 

When the color of light emitted by the blackbody radiation at a temperature of the same color, the temperature of the blackbody color temperature of the light source. The higher the temperature of the blackbody spectra of the blue component of the more, the red component is the less. Na przykład, the incandescent light color is a warm white, the color temperature is 2700K, the color temperature of daylight fluorescent method is 6000K.

 

Color Color rendering the property

 

In principle, the artificial light and natural light, people’s eyes are able to correctly identify the color of things, of course, according to the location and purpose of the lighting. Light showing the extent of object color is called color. Usually called "color rendering index (Na zewnątrz).

 

The color refers to things true color (their color) color display with a standard light source relations Ra value of the determination of eight test colors defined in the standard will IN9069 light source in the standard test light source done under the color the smaller the color showed that the measured light color, the better the light of Ra value of 100, said things in its light color and consistency in the standard.
