WAVELENGTH CONVERSION MATERIAL ARRAY |
摘要 |
A wavelength conversion material array is provided, including a system comprising: a light source configured to emit excitation light at an excitation wavelength; a heatsink; a wavelength conversion material located on the heatsink, the wavelength conversion material comprising a relative wavelength conversion area of unity divided into an array of spots, a number of the spots in a range of 4 to 12, the wavelength conversion material configured to emit light at a wavelength greater than the excitation wavelength when irradiated by the excitation light; and, an array of lenslets configured to: receive the excitation light from the light source and irradiate each of the spots of the wavelength conversion material with the excitation light, the lenslets in a one-to-one relationship with the number of spots; and collect the light emitted by the wavelength conversion material. |
