Abstract

A dimmer is an electronic device that controls alternate voltage applied to a lamp through delivering a selected portion of the mains sinusoid. Engineer, designing a dimmer needs to estimate how big this portion should be to get a desired luminance level. This article uses a model of incandescent lamp, tungsten resistivity, and human eye spectral efficiency to derive dependency of produced luminous flux over the voltage, gives a simple analytical function that describes this dependency with good accuracy (±2% comparing to the model).

Preface

I would like to discuss with you my ideas on new programming language for embedded applications, denoted further as e#. I value your time and therefore in this post I am trying to be short and precise as much as possible.

This post provides my look on MP ASM and an attempt to analyze and decompose it on parts. Despite this post provides ‘partitioning’ of a MP ASM only, many similarities can be found in other assemblers.
