Abstract (en)
[origin: EP2749813A1] The lamp has an LED module (2) arranged in lighting tubes (1, 3). Photo-end layers are provided for optical and/or spectral influencing of the LED module that emits light on an outer surface of the lighting tubes. The photo-end layers are coated with phosphor or painted with phosphorus. A diffuser is arranged on the outer surface of the first lighting tube. The photo-end layers comprise a shrink wrapping film that is wrapped around the lighting tube, where the film is made from polymer and provided with phosphorus particles and litter particle. An independent claim is also included for a method for manufacturing a tube lamp.
