Tips & Tricks - How to reduce LED light bulb brightness?
Ordinary light bulbs can be dimmed by changing their input voltage, the same cannot be said for LED lights. Can LED lights be dimmed? Well, of course they can! In fact there’s more than one way to achieve this. Here you can find out what you can do against LED lights that are too bright and dazzling.
1. Use a dimmer
Many light sources are only too bright in certain situations. To darken the lamp if necessary, the use of a dimmer is recommended. This way you can always adjust the brightness accordingly. LED dimmers are available for installation in place of the light switch and also as intermediate plugs.
2. Use resistors
Dimming an LED light is as easy as adding resistors to the connection or even several resistors, to ensure you get the right brightness – this is called analog dimming. In many states, there are regulations to the brightness (and colors) of LEDs on cars, which is why this is important to take note of.
When using resistors, you’ll need to know the power required for your project so you’ll calculate this using a LED resistor value formula like this one:
P = I^2_R
What this means is that power (represented by P) is equal to the current (Represented by I) in amps flowing through the circuit, which is squared and multiplied by the resistor value (Represented in R) in ohms.
3. Use a diffuser foil
Furthermore, there are so-called diffuser foils, which cause a scattering of the light. Depending on the installation situation, such a foil can be attached in front of the LED illuminant. Due to the wider light distribution, the light source no longer appears as bright.
