Led Lighting Technology


Operating Temperature

 This is the temperature of the environment in which the luminaire will be operated. All device life measurements issued by LED manufacturers are performed at different ambient temperature ranges. High ambient temperatures for a particular luminance will shorten the operating life of the device, and low temperatures will ensure that the LED will last longer than expected.


Led Lighting Technology


Standard International is a measure of the intensity of lighting. One candela is a lumen / steroidal. It was previously referred to as edil candle Daha. The illumination intensity of a light source in a given direction is expressed in candela (cd). Depending on the respective direction, any light source will have many different illumination intensities. Since the intensity of illumination itself is a characteristic of the light source, the candela value in a certain direction remains the same regardless of the distance to the source.

 Color Temperature 

Chromaticity is the absolute temperature of a black body that is very similar to the chromaticity of the light source. The associated color temperature (CCT) is a technical feature that defines the appearance of the color a lamp emits from a reference source when it is heated to a certain temperature, depending on the light color, and is measured in Kelvin (K). The CCT value of a lamp is that the light it emits is generally ış hot ı or Eri cold Bir. However, unlike the temperature scale, lamps with a CCT of less than 3200 K are generally considered to be ken warm Kabul light sources, while lamps with a CCT value above 4000 K are generally considered to be CC cold 32 in color. Light Efficiency: The total luminous flux of the lamp in total power. Expressed in lumens / watts (lm / W).

Led Lighting Technology

In light sources and lighting systems, efficiency is expressed in lumens/watts. When determining the system efficiency in fluorescent and high-intensity discharge (HID) lamps, the watt value of the ballast must also be taken into account, because a decrease in light output may occur due to the combination of lamp-ballast.

Led Ceiling Fixture

What is Led Ceiling Fixture? For years, human beings have used light to illuminate the places they have been and this has caused a variety of lighting materials. After entering the LED materials in our lives, most of the lighting materials have undergone many changes depending on the LED. Luminaires vary among themselves. types of luminaires, such as fluorescent type luminaires, round type ceiling luminaires and so on. However, the luminaires changed after Led.    Such as 60 × 60 Led panel luminaire, Led Ceiling Fixtures. There are also two kinds of luminaires in Led Ceiling Luminaires.    These; Led Led Ceiling Fixture and Led Ceiling Fixture (Led Bulb) is. Ceiling Luminaires are one of the most widely used Led electrical materials with its sensor types. Because of Sensor Led Ceiling Luminaires both energy saving an image with this Sensor Led Ceiling Fixture draws itself. Led Ceiling Luminaires with Sensors are very important in terms of ...

LED Technology The LEDs emit light in a certain part of the visible light spectrum depending on the material structure of the active layer. In other words, a single color light is produced and the material used in the active layer determines the color of the LED light. In high-light colored LEDs, different materials are used as active layers (GaAs, Gap, GaN, AlInGaP and InGaN). Producing white light with LEDs is possible in two ways. The first of these; red, green and blue is to obtain white light using three LED chips in a case. The second method is to produce white light by stimulating a phosphorus layer of light produced in the blue LED chip. They are covered in a variety of structures, mainly radial shape. They are produced with PIN pedestals for normal printing circuits, SMT (surface mounting technology) and directly on printed circuit boards. Benefits of Led Technology They provide high-efficiency lighting. It can save up to 80% by 40% compared to existing l...
