| 摘要 |
a radiation source, LED chip, (22) configured to emit radiation having a first wavelength range; a phosphor, photoluminescent material, (30) configured to absorb at least a portion of said first wavelength range radiation and emit radiation having a second wavelength range; and an optical component, lens, (26) through which at least said first wavelength range radiation passes. The LED is characterized in that the phosphor is provided on a surface (28) of the optical component. |
