OUTDOOR LUMINAIRE |
| 摘要 |
An outdoor luminaire comprising a blue LED chip having a maximum peak at a wavelength of 420-480 nm and a phosphor layer disposed forward of the LED chip in its emission direction is provided. The phosphor layer comprises a phosphor of the formula: Lu3Al5O12:Ce3+ which is activated with up to 1 mol % of Ce relative to Lu, the phosphor being dispersed in a resin. In scotopic and mesopic vision conditions, the luminaire produces illumination affording brighter lighting, higher visual perception and brightness over a broader area. |
