專利摘要(英)
A device for simply determining maximum permissible exposure time (MPE) of retina is disclosed, which principally comprises a light receiving unit and a core processor that is provided with a color temperature determining unit, a luminous flux determining unit and a calculating unit therein. The color temperature determining unit and the luminous flux determining unit are configured for completing a color temperature determination and a luminous flux determination of a light provided by a light source, respectively. The calculating unit is configured for calculating a maximum permissible exposure time (MPE) of retina of the light source based on a use distance and a color temperature and a luminous flux of the light. By using this device, generic users are facilitated to achieve the calculation of any one kind of light’s MPE by themselves, without needing to using any spectrometer.
