Abstract

PURPOSE: To offer the electronic desk calculator especially suitable for various illuminations calculations such as average intensity of illumination and point-to- point intensity of illumination.
CONSTITUTION: For example, when the calculation of average intensity of illumination E is calculated, the data for lamp light flux F is inputted with the entry key group D, and it is entered to the first address of the memory MM by depressing the memory key Ma. The required data such as utilization factor U and maintenance factor M are stored to the address corresponding to MM by depressing the memory keys Mb and Mc. Further, when the program selection key Pd is depressed, the operator CP reads out the data in MM, the caluculation of the average intensity of illumination E is made according to the incorporated illumination calculation program, and the result is displayed on the display unit V. In other illumination calculations, the required data are entried and the required program is selected, allowing to obrain the result.
