JIS C 8152-1:2012 PDF Download

JIS C 8152-1:2012 is a Japanese industrial standard that specifies the method for obtaining photometric measurements and determining the light source color of white light emitting diode (LED) packages used for general lighting purposes. The standard outlines the procedure for measuring photometric quantities such as CIE averaged LED intensity and total luminous flux.

It is important to note that the photometry of LED packages for general lighting should be performed in accordance with JIS C 7801. This standard covers the photometry of light sources for general lighting, including traditional bulb-shaped LED lamps.

For further guidance, JIS C 8152-2 and JIS C 8105-5 are referenced. JIS C 8152-2 provides the photometry method for LED modules and LED light engines, while JIS C 8105-5 pertains to the photometry of LED luminaires and other lighting devices using goniophotometers.
