LED, what exactly is that

LED lights come in many shapes and sizes nowadays. The development of LED is not standing still, which means that there are already good LED replacements for the most common fittings. The twist fittings (E27 and E14), bayonet fittings (GU10) and plug fittings (GU5.3, G4, and GU4) are widely used. LED lamps are also available for TL (T8), G9, R7s, and GX53. Enough applications, but what exactly is LED?

WHAT IS LED

LED stands for Light-Emitting Diode. A diode is an electronic component that conducts current. A LED is, therefore, a light-emitting diode. An LED always has a negative and positive side. The positive side has extra positively charged particles, the negative side has extra negative electrons. When current starts flowing through the diode, the electrons come into contact with each other. When a negative electron comes into contact with a positive electron, energy is released in the form of photons. Light consists of photons so the LED will give light.

WHAT DOES AN LED LAMP CONSIST OF

With only one LED you don't have an LED lamp yet. An LED lamp requires more than just the LED. For an LED it is important that it is supplied with the correct current. For this reason, an LED lamp has a driver. The driver is the electronic part behind the LED or LEDs which ensures the correct power supply. The driver also determines whether or not an LED lamp can be dimmed and with which dimmer it is combined. In addition to the electronic components, another important component is the possible lens or reflector. LEDs give themselves a broad light beam. By using a lens or reflector, this can be bundled to reduce the angle of light. Not all LED lamps have a lens, there are also spots with a wide light beam, instead of a lens a (diffuse) glass is used for the LEDs. Many other LED lamps such as fluorescent and incandescent lamp replacements also use glass or plastic around the LEDs. Depending on the type, this can be transparent or diffuse. By properly combining these materials, it is also possible to make LED lamps watertight, which means that lamps are also available for outside or in damp rooms.

VARIOUS TYPES OF LEDs

Until now we have always been talking about LEDs or LEDs, but there are also different forms in this. We distinguish among other things:

SMD (Surface Mounted Device) Hereby one or more LEDs are soldered to a printed circuit board.

COB (Chip On Board) Multiple small LEDs are placed on a chip. This produces a high light output from one point.

COG  (Chip On Glass) This is a technology where the LEDs are mounted on glass. This technique is used for filament lamps (incandescent lamp replacements).

COC (Chip On Ceramic) This is a technique where the LEDs are mounted on ceramics.

The popularity of LED lamps in the Netherlands and Belgium continues to rise

The popularity of LED lamps in the Netherlands and Belgium continues to rise These winter months in the Netherlands are not only dominated by the holidays, cold and dark, but it is also the period in which lamps, and in particular LED lighting, are purchased en masse. Since the LED lamp came on the rise in the Netherlands in 2007, this trend has continued unabated. GERMANY SET THE TREND The Germans started the online search for LED lamps in 2005, the Netherlands started two years later and Belgium only joined in 2009. Belgian consumers are still looking for LED lamps considerably more online: every year there is a greater peak in search volume during the winter months. Also in the Netherlands, fluorescent tubes and luminaires, halogen lighting is still being replaced at a surprisingly fast pace by energy-efficient LED lamps: online search behavior has been showing for eight years that the demand for LED lamps in the Netherlands continues to rise. For the time being, it appears tha...

DimFlame lamp

DimFlame lamp The light color of an LED lamp is no longer the "blue" light that used to be seen in the past. Yet we sometimes hear that the light color may be a little warmer when the lamp is dimmed. We hear this especially when a dimmable halogen lamp is replaced. When you dim a halogen lamp, it turns to a warmer color. An LED lamp does not normally do this, only the light output decreases when dimming. For this reason, LedLampenDirect has added a nice new product from YPHIX to the assortment. This is the GU10 Naos DimFlame lamp. Characteristic of this lamp is that it changes color when dimmed. At full strength, it gives light in a nice extra warm white color (2700K). This is comparable to a 50-watt halogen lamp. If you dim the lamp, it will gradually change to a warmer shade. To end up in the lowest position with an extra atmospheric color of 2200 Kelvin. The Naos DimFlame lamp is, therefore, an ideal replacement for those who want good light, but it is also nice to be...

What is CRI

What is CRI With LED lamps you often also see the color rendering or CRI / RA mentioned. For many an unknown value, but certainly not unimportant. We are happy to explain what CRI is. In a store, it often happens that people with clothing or accessories walk outside to see the color well. This is a good example of what CRI means. The light outside has a CRI of 100, this is the highest attainable. In this case, lamps with a low CRI value are hanging in the store, as a result of which the colors do not appear as they actually are. COLOR RENDERING INDEX CRI stands for Color Rendering Index. This index shows the extent to which you see the actual colors of objects in the light of a lamp. The CRI is expressed in a number between 0 and 100 Ra. Daylight (outside light) gives the colors the best weather, this is also light with a CRI of 100 Ra. The higher the CRI of a lamp, the better and more faithfully you see the colors. With older energy-saving lamps you will also come across a CRI ...
