century‚ electric companies were met with the task of maximizing the intensity of light bulbs as energy efficiently as possible. This was a newly emerging sector and no one at the time could fully explain the complete dependence of the intensity of black body radiation on its frequency/wavelength and body temperature. A black body is simply any physical body that absorbs all incident electromagnetic radiation (light). If at a constant temperature (thermal equilibrium) the black body will emit a characteristic

LIGHT DEPENDENT RESISTANCE INTRODUCTION In the society‚ some times street lights glow in day time due to any reason. In mines area people face many difficulties due to absence of light in the nights. In frontier and hilly areas‚ people face many problems due to damaged street lights. For solve above these problems‚ we create a device in which the lights glow in night and in day time‚ they off automatically and don’t glow. Due to use of it‚ we can solve above problems and can also save electricity

1.1 INTRODUCTION: In an automobile headlight‚ a ’meeting’ beam (dip beam) is provided in addition to the driving beam (high beam) so as to reduce the dazzle for those approaching head-on to the vehicle. The Auto Dipping Device for a head light is intended to automatically change the Headlight Circuit to either driving beam or dip beam given a particular set of road conditions‚ without the intervention of the driver. The present practice is to operate the dip switch manually. The function
