Dimming of linear halogen lamp with phase cut dimmers
Posted by Marcel van der Steen in Explanation, Lamps No Comments»
This is an article that shows the dimming results of a linear halogen light bulb that is dimmed by forward phase-cut (LR) and backward phase-cut dimmers (tronic, RC). The halogen lamp is well dimmable in the sense of dimming the amount of light. The images created show what that means in terms of light output as a function of dim-position.
What is remarkable is the amount of power still being high when the light has been dimmed a lot.
The graphs can be used to compare other types of lamps that are dimmed, in order to be able to judge whether the dimming works well or not.
