FIELD: electricity.
SUBSTANCE: group of inventions relates to lighting engineering. Backlight lighting device (24) is equipped with backlight base (22) with mounted LED unit (32) and a light-conducting plate (20), which lateral surfaces are light-receiving surfaces (20a). The LED unit (32) is faced to light-receiving surfaces (20a) of the light-conducting plate (20). The backlight base (22) has guide pins (40) protruding from the base plate surface (22a), at that the light-conducting plate (20) has concave connecting sections (38) at positions faced to the guide pins (40), while the guide pins (40) are coupled to the connecting sections (38). Lateral surface of each guide pin (40) is equipped with a through hole (40a), which passes through the above lateral surface.
EFFECT: prevention or exclusion of uneven brightness of the light emitted through the light-conducting plate.
