專利摘要(英)
The present invention discloses a device for simply determining maximum permissible exposure time (MPE) of retina. The device principally comprises a light receiving unit and a core processor. Particularly, there are a color temperature determining unit, a luminous flux determining unit and a MPE calculating unit provided in the core processor. After the light receiving unit received an illumination light from a light source, the color temperature determining unit and the luminous flux determining unit complete a color temperature determination and a luminous flux determination of the illumination light, respectively. After that, the MPE calculating unit is able to consequently calculate a maximum permissible exposure time (MPE) of retina of the light source based on a use distance, a value of color temperature transmitted from the color temperature determining unit and a value of luminous flux received from the luminous flux determining unit
