LED strip assembly

Image
LED tapes are more and more often used in interior design. They are most often used as additional lighting and they are used in kitchen tops, in suspended ceilings or around wall decorations, whose uniqueness we want to emphasize. In this article, we will show differences between individual LED strips, explain how to properly install them and suggest what additional elements will be necessary for their proper functioning. The correct installation of the LED strip LED tape should be glued to aluminum profiles, metal elements, flat bars or to any surface that can be used as a heat sink (heat dissipation) for the tape.  Before gluing, the surface must be degreased with a special preparation, cleaned and dried.  The tape should be soldered or using a suitable connector, connect the tape contacts with the power supply, and the power supply itself to the network through a cube or a socket plug.  Then tape the tape using double-sided tape, remembering that the glued surfa...

Street lighting yesterday and today

The basic element in the construction of each radiating source is a radiator,  which sends infrared, ultraviolet radiation or placed in a phosphor-coated  bubble , it can emit a visible light beam.  In addition, there must be power supply elements in addition to the heater in the equipment.  Depending on the type of radiator, we can indicate three basic sources of radiation. 1. temperature radiation - tungsten twisted-pair glow light source BULB  2. fumes of metals or noble gases (neon, xenon, mercury, soda, halides), in which the lighting effect occurs after the discharge phenomenon  The 3. semiconductor in the form of a LED light-emitting diode What are the discharge lamps? As the name suggests, it is a  lamp  whose light was triggered as a result of an electric discharge.  In contrast to the glow or LED, the discharge occurs in metal fumes (mercury) or gases (argon, neon, sodium).  Depending on the type of lamp and the dis...

LED technology in modern lighting

Image
LED technology in everyday use has revolutionized the contemporary look at the quality of lighting and the spectrum of its application. Depending on the individual needs of the user, a wide range of choice of the appropriate type of LED lighting , due to the diversity of the broadcasting power, will work both in terms of functionality and aesthetics, being a key element in the arrangement of internal and external space. LED technology A light-emitting diode, known as LED diodes (light-emitting diodes), is currently one of three basic sources of radiation. Immediately next to discharge or incandescent sources, it is currently one of the most energy-saving and, at the same time, efficient light sources. Contrary to appearances, the idea of ​​creating a luminous diode is not as young as it seems. The origins of the project should be traced back to the early 20s of the 20th century, then the Soviet radio technician - Oleg Ɓosiew- he noticed that the diodes, which are in the radio r...

LED - how does it work?

The operation of the LED for people who have little in common with the current can be complicated, but we will try to explain it as simple as possible.  It should start with the fact that in the diode there is a connector of two semiconductors that have different charges - PN is used for such a connector.  The carriers, in this case, are electrons with a negative charge and positive electron deficits, which are called holes or free places.  Light is generated by jumping electrons from layer N to holes from level P .  In this process, during the jump, electrons have a large surplus of energy, which is given out in the form of light.  The element of the diode, which changes the electric energy into light, is a semiconductor chip that conducts the current only one way.  It should also be mentioned that the intensity of lighting depends on the power of the supplied electricity. White diode and RGB Not everyone knows that white light does not exist in n...

HOW TO SELECT LEDs

Selecting lighting for my space should take into account the following: The quality of lighting The quality of lighting can be measured by using the CRI (Color Rendering Index). This index can take values ​​from 0 to 100, with natural outdoor light having a CRI index of 100. Substantially the natural light output in colors is the benchmark for all other light sources. In the case of fluorescent lamps, the CRI indicator is around 50-60 while in the case of LED lamps the CRI, depending on the brand of the lamp, is greater than 80. Specialty LED lights can achieve values ​​up to 98CRI. Kinds of lighting One of the most important parameters to consider when purchasing a light bulb is the type of lighting they offer. The color of the light required by a room (also called light color temperature measured in degrees Kelvin-K) depends on its use and can vary from hot to cold. Depending on the temperature of the light, the lamps can be divided into 3 categories, warm white, warm daylight...
