Abstract
A process produces self-illuminating bodies, in which a recess is made in a housing part of a housing and a fluorescent and/or phosphorescent layer and/or a mask is arranged on a boundary wall of a cavity which is formed by joining the housing parts together. The housing parts are connected in a gastight manner, with at least one feed opening from outside into the cavity remaining open. Furthermore, a medium emitting decaying radiation is introduced through the at least one feed opening into the cavity, the decaying radiation being intended to illuminate the fluorescent and/or phosphorescent layer. Furthermore, a self-illuminating body and also the use thereof are specified.
Claims25
Method for the production of self-luminous bodies, comprising the steps:
- making at least one depression in at least one of a first housing part and a second housing part of a housing,
- producing a layer formed from a substance that can be excited to produce light, via decay radiation, on at least part of a delimitation wall of at least one cavity,
- producing the at least one cavity via joining the first and second housing parts together,
- connecting the first and second housing parts in gas-tight manner, wherein at least one feeder opening remains open into the at least one cavity from the outside, and
- introducing a medium that emits a decay radiation for a substance that can be excited to produce light, or the substance and the medium, into the at least one cavity, through the at least one feeder opening,
- wherein closing and welding of the at least one feeder opening takes place via laser radiation.
Self-luminous body having a housing composed of at least first and second housing parts, and having a depression in at least one of the first and second housing parts, the first and second housing being connected with one another in gas-tight manner and enclosing a cavity,
- wherein two feeder openings to the cavity are provided, the at least one feeder opening extending from the outside into the cavity and closed and welded in gas-tight manner,
- wherein a layer of a substance that can be excited to produce light, via decay radiation, and a medium that emits decay radiation for a substance that can be excited to produce light are disposed in the cavity, and
- wherein the two feeder openings are closed off and welded shut via heat effect via laser radiation.
