dc.description.abstract | LED's have a lifetime of up to 30 thousand
hours. In addition, it has a level of effectiveness and efficiency
of 80%-90%. The current problem is to determine the
performance of the LED array arrangement using
conventional methods so that the LED array arrangement
must be made frrst and operated for testing. In this study, the
LED array arrangement test determines each test sample's
performance. mumination prediction computations were
performed on each sample using different test parameters.
The prediction of illumination has a different predictive value
in each test sample. The first and sixth samples have
prediction accuracy below 95%. However, samples 2,3,4 and
5 have prediction accuracy above 95%. The interests of the
current and temperature variables are 50% and 48%, while
the voltage is only 3%. The value of R2, which is not by the
research hypothesis, which is greater than 98%, is caused by
the ability of the dependent variable, namely limited
illumination. In addition, because the independent variables
are less varied, they do not provide information on the
dependent variable during the training data process. The low
R2 value can also influence by the ability of the prediction test
parameters formed. | en_US |
