1. LED strips new generation innovative lighting product with which spectacular lighting effects be created in an easy way They offer many advantages including small dimensions low heat generation higher energy efficiency more saturated colours and easily controllable As you will notice there are countless applications for LED strips Velleman offers a full range of LED strips and accessories this overview should give you a good impression of what is possible and how to implement your own personalized lighting application Generally LED strips can be divided into 2 main groups flexible and rigid non flexible strips In this tutorial and selection guide we will only focus on flexible LED strips as they are most frequently used Selecting the right strip for your application is a 5 step process 1 Select a strip according to the place where it will be used indoors outdoors 2 Determine the length and the desired number of LEDs per unit of length length in meters and desired nr of LEDs per meter 3 Select the colour single colour or RGB 4 Select a suitable power supply voltage and power 5 Select a suitable controller dimmable remotely controlled DMX controlled 1 Select a strip according to application area Mainly there are 3 types of LED strips which can be used in different environments Bare strip no protection against dust or water Ideal for indoor applications e g in or2. Output Voltage jOutput Power 100W 80W 100W LPS10024R 100W Unlike individual LEDs LED strips are constant voltage devices and must be powered by a constant voltage LED power supply and not a constant current LED power supply 23 04 2010 4 OVelleman nv WGLeMeh 5 Selection of the controller There are numerous controllers on the market which makes it hard to determine the right one for your application The most important criteria for choosing a controller are e The voltage power and current handling e The ability to dim LED strips PWM is preferred e The ability to directly control RGB strips and colour mixing capabilities and or built in fading effects e means of control manually through domotic systems 0 10 DMX remote control Combinations are almost endlessly Check our controller selection guide on the next page 23 04 2010 5 OVelleman nv RGB LED 501 Pee controller B tio 12 24VDC Spe 6 2 N 5 RF 3A 12VDC A 1A 24VDC RGB LED BOC controller 6 2 RF 3A 12VDC 1A 24VDC re 1 VM152 LED dimmer N A 5 12 24VDC VM161 RGB LED 3A 12VDC VM118R 6 1A 24VDC RGB LED ze OO dimmer 0 10VDC DIN is 0 10VDC 12 24VDC Professional VMBILED LED dimmer 5 28 DIN rail

5. More LEDs per meter More light output more uniform light distribution better for direct lighting Higher current power ratings which has impact on heat total length power supply and controller Less LEDs per meter Less light output more dispersed light distribution especially suitable for indirect lighting Lower current power ratings which has impact on heat total length power supply and controller Is it possible to interconnect LED strips to create longer distances Yes but keep following limitation in mind Each LED strip will consume the same amount of power If LED strips are interconnected the total power and thus current trough the LED strips increases and this current is limited by the design of the strip check the LED strip data sheet for ratings and limitations Example You need a total LED strip length of 20m blue LED strip with 60 LEDs per meter Velleman CHLS3B It would seem logical to just interconnect four full length strips of 5m to reach 20m In the data sheet you find that a single CHLS3B needs a 12Vdc supply and draws 1 5A current 18W power If current or power is not rated use Joule s law Power W Voltage V x Current A or Current A Power W voltage V If you interconnect 4 strips the power increases to 4 x 18W 72W and current increases to 4 x 1 5A 6A This current must pass through the first strip to reach the last strip Due to design limitations the tracks inside the LED strip can o
6. he total length which determines how much output power Watts your supply must be capable of delivering The currents or power ratings are a standard specification for each LED strip and can be found in the data sheets For interconnection of LED strips see 2 Example We assume the same example of 82 for calculation of the power supply 20m Velleman CHLS3B In 2 we calculated that only 2 strips may be interconnected which totals to 10m Since we need 20m we must still connect 2 of these lengths in parallel to the power supply As we already calculated we need 4 x 18W 72W What we are looking for is a protected 12Vdc supply which is capable of delivering a power of at least 72W 23 04 2010 3 Velleman nv It is always wise to slightly overrate your power supply safety reasons so in this case a 12Vdc 80W LED power supply seems adequate e g Velleman LPSO8012R Velleman currently offers 2 ranges of power supplies that can be used to power LED strips There is the low to high power range of so called bare industrial power supplies PSIN series for indoor dry location use only These range up to 300W aa 2av _ 51 04024 av PSIN10012 PSIN10024 150W 300W And we offer the waterproof IP68 power supply series LPS series which can be used outdoors or in highly humid environments The maximum power of these is limited to 100W
