Some Components Applying about RGB LED Strip Lights

The RGB proved to be one of the most popular products at LEDcentre. Its wide range of application allows customers to use more of their imagination, decorate and create new moods in their homes or businesses to their own tastes. The most common application in businesses can be found in bars, clubs, restaurants or stage lighting for bands. Besides commercial use, household application is also very common in the kitchen or living room for instance, where mood lighting is often used. When it comes to mood lighting, and picking colours, the user’s imagination is the only limit. Both in household and commercial uses, the is applied to enlighten edges of furniture, worktops, to give a touch of colour to walls, corridors, columns, steps and staircases, illuminate audio visual systems, is used as a party set or background setting for bands.

The two basic components to operate RGB LED strip lights are the RGB LED strip (obviously) and a matching RGB controller. All RGB LED lighting systems require a controller, with which you can determine the colours displayed. The number of effects you can achieve with your RGB LED string depends both on the tape, and the controller you apply it with. The simplest RGB LED tape has a fixed set of colours that can be displayed in a pre-programmed sequence.

Once you decide on going for RGB LED strip lights, the technical details you have to pay attention to are the following. LED strip lights often do not operate at mains, but are low voltage lights. If so, you need a transformer to connect them to the mains, or you can operate them with batteries of the adequate voltage. LEDs require transformers specially dedicated to them, so electronic transformers are not suitable, for instance, and also the majority of LEDs require stabilized constant voltage powering. Voltage tolerance may also have significance if you operate the lights from a battery or an engine (power supplies need to be stabilized, so this problem doesn’t occur with them). On boats, yachts or caravans, Voltage increases when the engine is on, for instance. If you would like to apply any low voltage LED lights of this kind, always check the voltage tolerance of the light among the technical details. When you decide on the strip light, pay attention to the followings: the size and performance of the light-emitting diodes included in the strip, the technology of the LEDs (low power, SMD power or high power), the light emitted, its IP rating, the direction of the light or the diodes, and its coverage. Also, obviously, the range of effects you will be able to achieve with the RGB LED tape depends on the knowledge of the strip, so check what colour range it provides, or if they can be used with DMX RGB controllers (which provide a full range of mixing colours and widest range of effects).

The technical details of the controller are also significant. The controller determines the performance of the strip lights it can directly be connected to. For example, if the controller is suitable for let’s say 140W performance, and the performance of the RGB LED strip light you will use is 7W per metre, than you can connect 140/7=20 metres of strip lights to it. If you wish to control more than that, but synchronized together; you will need an RGB amplifier that forwards the signal of the controller. However, since the power that can run through the RGB controller is fixed, the amplifier needs to be powered directly from the transformer or the battery. The connection mode of the LEDs you have will determine the connection mode of the controllers you can use. RGB LEDs have four pins. Three of these pins are for the colours (RGB), the pole of these pins determine the type of connection. If the LED light or strip light has three positive and one negative pins, the connection is common cathode. If it is the other way round (three negative, one positive), the connection mode is common anode.

How does RGB LED technology work?

RGB LEDs essentially comprise three LEDs employed in one. The mixture of those three colours handles the complete array of colours. The RGB controller performs with PMW (pulse-width modulation), which signifies – at a specific volume – it turns the LEDs on and away completely (this is especially precisely the exact method solitary coloured LEDs are dimmed). in circumstance you turn the blue LED away certainly for instance, the red-colored and eco-friendly will produce a yellow gentle together. The color could be manipulated using the volume in the person or ladies LEDs on and away modes. in circumstance you include a tad of blue to this yellow, you will obtain a lighter eco-friendly shade. To produce just one color output the volume in the complete LED should be over 50Hz.

So, what is on the way to be the complete assortment of effects feasible with RGB LED strip lighting?

The simplest RGB LED string lights possess a pre-programmed founded of color they are able to emit ranging from 4 to 16, as well as the colours rotates in accordance with these programmes. The assortment of colours displayed could be widened using the knowing in the strip and certainly the knowing in the controller. RGB LED ribbons which allow DMX controllers can show different million colours. apart from the common RGB LED strip lights which could emit different shades of colours, but only just one at a time, exist the several color strips – also regarded as miracle LED strips or pixel LED tape lights. This sort of RGB LED rope gentle calls for a specific RGB controller. RGB LED strip lights are most usually marketed using the controllers ideal for their operation, or there may properly be considered a report of advised controllers indicated in the strip light’s description. Controllers can essentially be manual, automatic, semi-automatic, pre-set sequence or DMX.

Besides probably the most usually employed pre-set sequence RGB controllers, a well-liked remedy for developing your non-public effects is DMX controllers, which allow consumers a broad assortment of settings in the brightness, the color as well as the pace of color altering in the strip light. DMX controllers enable one to founded the level of brightness, usually possess a assortment of colours over different millions, unique fee of show or color change, this fee can usually be founded to stick to the rhythm of music. With this broad assortment of possibilities to produce your own, one of a kind lighting, only your imagination is on the way to be the limit.
