LED Strip is a thin (0.25mm) flexible ribbon with copper conductors and electronic components e.g.   LEDs, resistors, IC etc., mounted on the surface. Width may vary from 5 to 20mm and length from   30 cm to 40 meters. Certain models have self-adhesive tape to easy installation. LED Strips can be   cut every few centimetres (2.5 to 10cm depending on model) with cut off line usually market with a        sign     . LED Strips are becoming increasingly popular as decorative element in both private and   commercial space.   The “Great Wall” strip does indeed look like a world famous wall. The only small difference it’s actually build of LEDs rather than stone blocks. Inside of the “Great Wall” DIP LEDs mounted on flexible PCB and buried in transparent silicon tube or clear epoxy.
Made with Xara  LED stands for light-emitting diode. That is, simply,   a semiconductor device that converts electricity to   light by using the movement of electrons. LEDs were   invented in Russia in the 1920s. They were put into   practical use in the United States in the 1960s by   General Electric . In the late 1960s, Monsanto   Corporation was the first to mass-produce LEDs, and Hewlett-Packard used them in its early calculators.   Want to know more?

DIP: double in-line package, this is the traditional LED package technology.  LED Bar is a chain of LEDs mounted on hard PCB typically fibreglass or aluminium. Rigid LEDs comes in Waterproof or Non-Waterproof variation and also multiple casing options. Compared to LED strips bars are more robust and often used in construction and machinery due to its ability to withstand significant mechanical impact. Also popular in trucks and boats as marker lights or day lights. LED Bars (Rigid LEDs)  This is a kind of product where LEDs are fully exposed. Indoor moisture or dust are OK for them, but don’t spill coffee or drop into a fish tank, good chances they won’t survive. NON-Waterproof Decorative LEDs  Water-Resistant LEDs have some sort of protective material above LEDs. Typically this is transparent soft Epoxy Cover or Silicon Tube. Protective material makes them tolerant to liquids or mechanical intrusion, plus outer surface is smooth and easy to clean. Water-Resistant Decorative LEDs  Fully Waterproof LED strips (IP68) are multi-layer protected, have highest available defence grade and the only product that can be permanently submerged. Silicon tube filled with Epoxy glue is the most popular protective combination for Waterproof LEDs. Waterproof Decorative LEDs  LEDs Per Meter refers to number of LEDs installed on one (1) meter of PCB. Generally speaking more   LEDs leads to brighter light. In some cases where exceptional brightness required on relatively small   space LEDs could be packed in multiple rows or in clusters. Package density usually limited by mean of   heat dissipation or current. Single row LEDs usually packed in 30, 60, 90 or 120 LEDs per meter. Those   numbers could be relatively easily customized and numbers like 99/100, 72 or 140 are not uncommon.  LEDs per Meter  Number of LED’s models currently on market is literally uncountable. Every manufacturer has own classifications and hundreds of models. Models vary in sizes, colours, brightness and who knows what else. From the Decorative LEDs perspective most popular models are SMD (Surface Mounted Device) 3528, 5050,335 (side emitting) and DIP 3mm and 5mm LEDs. LED MODELS  SMD 3528 refers to Surface Mounted LEDs packed in 3.5mm by 2.8mm case (that’s where it marking comes from). Some time it also referred as 1210 in imperial (US) metrics. This is basic LED model with single p-n junction, available in Red , Green , Blue , Yellow , Cool White and Warm White colours.   LED SMD 3528  SMD 5050 refers to Surface Mounted LEDs packed in 5.0mm by 5.0mm (or 5.0 x 6.0mm) case. The 5050 model consists of three p-n junctions (3 smaller LEDs) and by simple maths should be three times brighter then single junction models like 3528 or 335. But, in reality brightness of 5050 is only around 2.5 times of lower models. LEDs packed within 5050 case could be either of the same colour (monochromatic) or consists of different colours typically Red-Green-Blue (RGB). Combination of three primary colours is able to produce whole spectre of colours, thought in order to use this capability a RGB Controller is required.   LED SMD 5050/6060  By its optical and electrical characteristics model 335 is identical to 3528. Distinctive characteristic for model 335 is that it side emitting,where models 3528 and 5050 are top emitting. Side emitting means that light beam direction is parallel to the surface where LED strip is mounted. This unique characteristic allows LED Strips of 335 series to be mounted in very narrow space 2mm wide and 6mm dip. Available colors: Red , Green , Blue , Yellow , Cool White and Warm White.   LED SMD 335  Colours of modern discrete LEDs are not only cover whole visible spectre, but also good chunks of Infra-red and Ultraviolet. And thought the colour options are endless, under the decorative angle of view the most popular are primary colours i.e. Red , Green , Blue and also few secondary colours like Yellow and Pink . Colours in between are often generated as combination of three primary colours. LED COLOURS  Warm white is rather natural or sun appearance color. Nice and soft, does not irritate eyes and is the closest to incandescent light. Most popular in places where people relax like bedrooms, lounges, hallways etc. WARM WHITE Wave length (WL)  - 2700-3000K COOL WHITE  Very bright white with sort of bluish tones. Blue tones in the light improve our ability to see contrast and as such is good in workspaces like kitchen, workshops, offices etc. Wave length (WL)  - 4000K RED  Wave length (WL) in range 640 – 650 nm BLUE Wave length (WL) in range 450-460 nm GREEN Wave length (WL) in range 550-560 nm RGB R G B LED is a combination of three discrete primary colour LEDs in single case. Playing with different colour combinations and light intensity up to 16 million colours c an be generated.  The IP Code (or International Protection Rating, sometimes also interpreted as Ingress Protection Rating) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. (See the whole article at Wikipedia ). IP CODE Protection against hazardous parts (e.g., electrical conductors, moving parts) and the   ingress of solid foreign objects.                Protection against harmful ingress of water IP20  Fingers or similar objects                                       Not protected IP65 No ingress of dust; complete protection against contact                                                                     Water projected by a nozzle (6.3mm) against enclosure                                                                                  from any direction shall have no harmful effects. IP68 No ingress of dust; complete protection against contact                                                                   The equipment is suitable for continuous immersion                                                                                 in water under conditions which shall be specified by                                                                                 the manufacturer. Normally, this will mean that the                                                                                 equipment is hermetically sealed.
