LED strip or LED tape is a versatile lighting solution thatprovides endless possibilities. Let me start by explaining what it actually is:LED lighting strip in its essence, is a continuous row ofLEDs that have been soldered together with resistors to form a circuit. Whenpowered by a power supply or driver, the LEDs produce a seamless light, similarto a fluorescent. LEDs are low voltage and require a DC (direct current supply)which is usually 12 or 24 volt DC. When connecting the strips to a mainsvoltage power source, the use of a power supply of LED driver must be used. Thepower of the driver is determined by the wattage and the length of the strip. There are three main types of LED strips; the first is nonewaterproof. This version is the most basic and fragile as the LEDs are placedon a piece of card or plastic without any cover to protect them. The secondtype silicone coated, this is waterproof and rated at IP65. This version ismade up of a similar row of LEDs but is covered by a clear, thin siliconelayer. The silicone version is not self adhesive, when sticking this to asurface, double sided tape or an adhesive must be used. The third version,which in my opinion is the best, is the epoxy coated LED strip. This versionprovides greater protection as the LEDs are sealed and set into the epoxyresin. This version is waterproof, rated at IP65 and self adhesive. The epoxyversion infuses the best assets of the other LED strips. These variants are only the construction of the lightingstrips. Within the strips there are many types of LED chips that could be used,ranging from smaller dimmer chips to larger brighter chips. When larger chips areused, the strip needs to be wider to house them. The LED chips that are used instrip lights are called SMD which stands for surface mount device.LED strip has been used in commercial applications for manyyears but until recently was deemed too expensive and complicated for householduse. As the price of LEDs gradually decreases due to higher demand and massproduction, LED strip is now more accessible. Easy to order, plug and play kitsallow consumers to fit it themselves and many people are realising the fullpotential that LED strip has to offer.One of the fastest growing areas that LED strip is used isunder kitchen cabinet use. The benefits of using the lighting strips here isthat they can be cut to almost the exact lengths that are required (within 50mm).Basic installations can be done in a matter of minutes as the strips can bestuck directly to the cabinets using the self adhesive backing. Then plug the powersupply straight into a standard wall socket and the job is done.Some commercial projects can get quite complicated, whenmultiple colour changing strips are used and they all need to be controlledfrom one main device. This is when a DMX (digital multiplexer) controller mustbe used as the DMX converts a basic digital signal into a PWM (plus-widthmodulation) signal. When the strips have been converted into a PWM signal theycan then be controlled by computer based software that allows anything fromcolour changing to scene setting.For new users to LED strips, the options can seem dauntingbut most companies have now realised that there is no need to stock every typeof strip available when one type will cover most applications. The mostuniversal strip is the epoxy coated with SMD 5050 LEDs. This version isavailable with 30 LEDs per metre or the super bright 60 LEDs per metre. Evenwhen you have selected your type of strip, different variations exist as theyare manufactured in different factories which have different quality controlprocedures.Controlling the strip can be done by using a basic on/offswitch, a remote control or by using computer based software via a DMX decoder.The most advanced way is to control the lights from an Iphone or smart phone,this allows you to dim or change the colour of the strip in your kitchen fromanywhere in the world! This is a great way to frighten the rest of thehousehold when on holiday or working away.LED strips can be supplied in very short runs ranging fromjust 50mm up to 100s of metres. The use of hard wired, heavy duty powersupplies must be used on longer runs. Hard wired installations should be doneby a qualified electrician but shorter runs (around 10 metres) can be done byalmost anyone as no tools or electrical knowledge is required.
