FREQUENTLY ASKED QUESTIONS EXPOLED Voor al uw vragen over Led. What exactly is a LED? AnswerThe abbreviation LED stands for the English '' Light Emitting Diode ''. This literally means a light-emitting diode. A diode is an electronic component. Usually this component is placed in a very small casing so that the light is better displayed and the LED itself does not break down. Although the abbreviation is LED, the Dutch language union has decided that the word is so common that it can also be written in small letters. When was the LED invented? AnswerIt is not known exactly when the LED was invented exactly.We do know that the Russian Professor Oleg Losev during the years20 of the last century the first discoveries and tests did with LEDlighting. Although he himself was convinced of the operation of the LED lamp, the new light source received little attention. It was not until the 1960s that people really continued to apply the LED lamp. In 1962, Nick Holonyak was able to manufacture the first working LED. What were the first applications of LED lighting? AnswerThe first applications of the LED trunks from the 70s. At that time the first LEDs were used as indicators in, for example, remote controls. LED was also soon used for traffic lights. The next step was placing LED lighting in flashlights and lighting for the bicycle. Nowadays many streetlights are also provided with LED lighting. The nice thing about the LED is that you can also give all those small LEDs a different color, making it possible to create RGB lighting. What are the current developments in the field of LED? AnswerMore and more private individuals are now also switching to LED lighting. This is because the LEDs become increasingly powerful and better light colors are also possible. At the beginning of the introduction of LED lighting in the Netherlands, people were very skeptical. Meanwhile, however, there are LED lights with an 'extra warm' light color on the market so that you can match the light of the traditional light bulbs.In addition, LED lighting is becoming cheaper because it is used more. Many companies therefore also switch entirely to LED lighting. The government encourages this transition by allowing companies to deduct part of the purchase amount from the tax. It is expected that all lamps in the future will be equipped with LED lighting.. What are Low power LEDs? AnswerThe first type of LEDs on the market were the low power LEDs. These are the same kind of LEDs that you would also encounter in your remote control. For normal LED lamps, these LEDs were also used first. Partly because of this many people were disappointed in the first LED lamps that came on the market. Wat zijn High power leds? AntwoordOmdat veel mensen sceptisch waren geworden over led verlichting moest men opzoek naar een manier om meer vermogen uit de leds te krijgen. Toen zijn de zogenaamd high power leds ontwikkeld die tot wel tien keer meer vermogen konden hebben als de low power leds. What is SMD? AnswerNowadays you see more and more lamps and spots with those flat LEDs, which are the SMD LEDs. The SMD LED comes in different types: the 3528SMD and the 5050SMD. The last SMD is larger and therefore provides a higher light output. These LEDs are also used for making lightbox LED modules. What is Kelvin (color temperature light color)? AnswerThe light color is always indicated with a certain color temperature. For this the number of Kelvin is the yardstick. A warm light color has a low number of Kelvin, for example 2300K. A warm white light color slightly higher, 3000K. A cold (almost blue) light color is usually 5000-6500 Kelvin. What is the beam angle? AnswerThe beam angle indicates the extent to which the light from thelamp shining in width. This can differ from a narrow light angle of, for example, 30 degrees to a wide light angle of, for example, 180 degrees. A narrow beam angle is used to illuminate a small area and for a larger area you can better choose a lamp with a wide beam angle. What means CRI? AnswerThe color rendering of lamps is sometimes displayed in a so-called CRI index. The number of Ra indicates how light colors are perceived by people. A low CRI index means that the light is not easily detectable and a high number of Ra (more than 80) means that the light is clearly visible.

AnswerFor the packages in the colors black and white the delivery time is on average 3 working days, provided they are available in stock. In case of different colors the delivery time is 10-15 working days. What is the gloss-rate of the panels? ExpoSupply floor and wall panels are available with a matt and high-gloss finish.When a surface acquires the meaning of matt or high gloss, it is based on certain calculations.Learn here for more information: www.gloss-meters.com/GlossIntro2.html#4The instrument for measuring the gloss-rate of the panels is placed at 60 °.The high-gloss finish is set at 95 (from 100 theoretical)With the matte finish the gloss-rate is 7-9 (for the dark colors) and 8-10 (for the light colors) EXPOPANEL Voor al uw vragen over ExpoPanel. How do I install the ExpoPanel wall panels? AnswerThe 6 mm panels can be mounted in existing systems of modular stand construction. Velcro tape is used for this. This is applied to the panels and on the frames. Exposupply can deliver this tape.The 10 mm panels can be used without a frame. For this a construction has to be made for it.
