專利摘要(中)
本發明主要揭示一種視網膜安全提升指標的量測裝置,用以簡易量測一光源之一視網膜可容許曝照時間,且主要包括一光接收單元與一核心處理器。其中,該核心處理器之中設有一色溫測定單元、一光通量測定單元與一視網膜可容許曝照時間計算單元。在該光接收單元接收該光源的一照明光後,該色溫測定單元與該光通量測定單元分別測定該照明光的一色溫及一光通量,使得該視網膜可容許曝照時間計算單元能夠依據該使用距離、該色溫、該光通量而計算出所述視網膜可容許曝照時間。
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
