Lighting Gateways and Converters: How to Choose
Gateways and converters connect LED lighting with DALI, DMX, 0-10V, Wi-Fi, Bluetooth, KNX or a smart-home system. A gateway passes commands between protocols, while a converter changes a signal, voltage or interface so equipment can work together.
Short answer: use a gateway to connect systems, such as DALI and DMX or Wi-Fi and KNX. Use a converter when one device's signal does not match another device's input, for example converting 0-10V to PWM or DMX to 0-10V.
Gateway or converter: what is the difference?
| Device | Purpose | Example |
|---|---|---|
| Gateway | Connects protocols | DALI ↔ DMX, KNX ↔ DALI |
| Signal converter | Changes command format | 0-10V ↔ PWM, DMX ↔ 0-10V |
| Power converter | Changes operating voltage | 24V ↔ 12V |
Important: a gateway does not replace an LED driver or power controller. It passes commands, while the output type, load and power must match the connected equipment.
When do you need a gateway?
Use a gateway when the lighting works in one system but must be controlled from another. For example, a DALI driver can be connected to building automation through a KNX gateway. The device passes scene, group, on/off and dimming commands.
How to choose a converter
Identify the input and output signals, conversion direction, supply voltage, channel count and maximum current. Check support for PWM, 0-10V, DMX, DALI, RS-485 or another required interface.
Frequently asked questions
Does a standard LED strip need a gateway?
No, unless it must connect to an automation system. A compatible controller or dimmer is enough for basic control.
Can DMX be converted to an LED strip signal?
Yes, with a DMX decoder or converter that has the required PWM output.
How does a gateway differ from a converter?
A gateway connects systems, while a converter changes a signal, voltage or interface.
Conclusion
A gateway connects control systems, while a converter matches a signal, voltage or interface. Before choosing, check the protocols, communication direction, channels, power, voltage and mounting method.
