Design and Implementation of a Digital Luxmeter for Investigation of a Lighting Standard

الملخص

The aim of this research is to design and implementations of a digital lighting meter (or Digital Luxmeter DLM) and use it to investigate, establish and test a proper standard for good lighting in our different living environments in order to have a good human health. An electronic circuit was designed and implemented experimentally as a digital lighting meter (or digital Luxmeter) and by using our digital Luxmeter we found tables of readings of that circuit which as decimal numbers related to the light intensity for making the good lighting standard. The standard was tested by taking different lighting, living environments and recording the response of groups of people. The results was discussed and founded the stander deviation of that’s responses. Finally, by conclusion, establishes this standard we tried to find the optimum of the good lighting conditions in our different living environments.
