FIELD: physics.
SUBSTANCE: invention relates to light-emitting devices. Device (100, 200, 300) comprises solid body (10) having surface (11), light guide element (101, 110) partially embedded in said body, and multiple solid-state light sources (12). Light guide element has a plurality of discrete light output areas (103), having light output means (230, 730, 830, 930) distributed along the longitudinal direction of the light guide element and a plurality of discrete light-emitting areas (102) distributed along the longitudinal direction of the light guide element. Plurality of non-light-emitting areas of light-guide element is embedded with said body, and plurality of light-conducting element light-emitting elements is open on surface of said body. Non-light-emitting regions (102) form light-input regions containing light input means (220, 320, 420, 520, 620). Plurality of solid-state light sources (12) is embedded inside said solid material body (10) and is arranged to emit light towards said light input regions.
EFFECT: invention provides reduced light losses.
