摘要:
The invention provides an illumination device (100) comprising a translucent exit window (200), one or more transmissive windows (300), arranged upstream from LED(s) and downstream from the translucent exit window (200), and one or more luminescent material layers (400), which may particularly be coated to the downstream and upstream faces of the transmissive windows (300).

摘要:
A method for the manufacture of a wavelength converted light emitting device is provided. A light curable coating material is arranged on the outer surface of a wavelength converted light emitting diode. The light curable coating material is cured, in positions where a high intensity of unconverted LED-light encounters the curable coating material. The method can be used to selectively stop unconverted light from exiting the device, leading to a wavelength converted LED essentially only emitting converted light.
摘要:
A method for the manufacture of a light emitting device is provided. The method comprises the steps of: providing a substrate (102) on which at least one light emitting diode (101) is arranged and; arranging a collimator (103), at least partly laterally surrounding said at least one light emitting diode, by bonding said collimator to said at least one light emitting diode and said substrate using a transmissive bonding material (104). By using the inventive method, the collimator can be arranged after the placement of the LED, which facilitates the placement of the LED.
