Dimmable led8/15/2023 The advantage here is that only one component is required for dimming. The LED strips are also connected to the LED transformer. The LED transformer is supplied directly with the power supply (230V). These are LED transformers where the dimming level can be set directly via the DALI or DMX interface. Option 4 - LED transformers with integrated PWM dimmer Not only single-colour but also multi-colored (DUAL-White, RGB, RGBW) LED strips can be controlled. The desired degree of dimming can be set in many different ways (DALI, push-button, 1-10V, wireless, Bluetooth, WLAN with additional module). The additional PWM dimmer is installed between the power supply and the LED strips. This variant offers maximum flexibility and is also suitable for retrofitting in existing installations. Option 3 - Fixed voltage transformer with additional PWM dimmer Casambi)ĭimmable transformers are particularly suitable if the LED strips have only one light colour. This solution is also often combined with radio modules(e.g. The principles are different and depend on the respective type. The output voltage can be changed or switched via a control voltage such as 1-10V, a potentiometer, a DALI signal or a PWM signal. Some manufacturers offer LED transformers with an additional control input. Option 2 - Transformer can be dimmed via external control cable This solution is often used if only the existing three lines (L, N, PE) are available in the house installation. The LED strips are then simply connected to the LED transformer. Here, the LED transformer is switched directly after the phase dimmer. Special dimmable LED transformers can be used with commercial leading/ trailing edge dimmers. Option 1 - The transformer itself is conventionally dimmable. The operating devices must be aligned accordingly, depending on the various control options on the user side. The operating voltage is switched on or off for different periods ( Pulse Width Modulation). 12V or 24V is reduced in the output voltage. These convert the input voltage into an analog current for the LEDs, so that the following dimming variants are possible. It is done by current control, realized via other electronic components. Nothing happens under this threshold value, and only at a certain voltage level the brightness does suddenly increase. LEDs are electronic components, so-called semiconductors, and require a certain voltage to light up. Whatever classification of bulb you need, you’ll have plenty of options when it comes to wattage, temperate and energy efficiency, thanks to Toolstation’s comprehensive selection of LED light bulbs.While incandescent bulbs can be dimmed relatively easily by reducing the voltage, this is no longer that easy with LED strips. Across our product selection you’ll find everything from frosted E27 globe bulbs which give off a warm hue, right through to vintage LED filament bulbs that really make an impact. Lamp lighting is the number one way to add some ambience around your home. Across our range you’ll find everything from GU10 bulbs that fit standard downlights to GX53 circular LED light panels, as well as white LED lights that are ideal for utility spaces and dimmable LED bulbs for added effect in your living areas. They’re far more energy efficient and also last much longer – for as much as 30,000 hours – helping you save on your energy bills as well as on the cost of replacing bulbs all the time. Warm LED bulbs have long since overtaken classic incandescent bulbs as our primary source of lighting. With LED bulbs in all shapes and sizes, and from leading manufacturers like Meridian Lighting, Integral LED and Philips, we’re confident we have exactly the bulb you’re looking for here at Toolstation – many of which are available in packs of 5 or 10 and at friendly low prices. Small, powerful, and energy efficient, the humble LED has become the staple source of lighting in and around every UK home.
