FIELD: lighting engineering.
SUBSTANCE: invention relates to lighting engineering. Bulb comprises integral shell (102) mounted on base (104), an inner structure (106) disposed within shell (102) and comprising stem (108) extending from base (104), solid-state light source (110) disposed on stem (108) and screen (112, 212) obscuring at least part of the light emitted from solid-state light source (110), in such a way that the light emitted from solid-state light source (110) is scattered by screen (112, 212). Stem (108) is configured to hold screen (112, 212). Screen (112, 212) is adapted to transition between a compressed state in which screen (112, 212) can pass through base opening (115) of shell (102), and uncompressed state (116), in which screen (112, 212) can not pass through base opening (115) of shell (102).
EFFECT: technical result is the achievement of effective uniform lighting.
