Abstract:
A method for installing a lighting device (10), such as, for example, an LED module comprising an elongated body having a first, light-emitting surface (10a) and at least one second rear (10b) or side surface, with an encapsulation layer at the second surface (10b), and a distribution of electrically-powered light radiation sources (12) arranged in the elongated body along the length thereof to project light radiation towards the light-emitting surface (10a). Electrically-conductive formations (14) are provided for transferring electrical signals with respect to the light radiation sources (12), which pass through one or more passageways (140) in the encapsulation layer (100) at the second surface (10b).
Abstract:
The present invention relates to a method for producing an LED module and an LED module, by means of which a high out-coupling efficiency and homogeneity of the emitted light can be provided. In the method according to a first aspect of the invention, a housing (26) is initially provided, which has a base side (28) on which a circuit board (36) with at least one LED (32) is arranged. In addition, at least one first base layer (22) made of a curable material is poured in a non-cured state into the housing (26). A scattering layer (24) made of a curable material is also poured into the housing in a non-cured state. The scattering layer (24) is poured onto the first base layer (22), the first base layer (22) not being cured when the scattering layer (24) is poured in, and after the scattering layer (24) is poured in, the at least one first base layer (22) and the scattering layer (24) are cured.
