FIELD: lighting.
SUBSTANCE: light-emitting structure comprises of a set of light-emitting elements (20) disposed on a carrier (10) having an inner surface (11) which faces the interior space at least partially enclosed by said carrier, and an outer surface (12). The light-emitting elements (20) are disposed with their light-emitting surfaces inwards, with the possibility of emitting light towards the interior space, a tubular wavelength convertion element (30) having an enveloping body which includes an inner enveloping light-receiving surface (31), directed into the interior space which is partially enclosed by said wavelength conversion element, and an outer enveloping surface (32). The wavelength convertion element (30) is adjacent to said carrier (10) for receiving light, emitted by said light-emitting elements (20) through said inner enveloping light-receiving surface (31).
EFFECT: increased light output by improving cooling.
