FIELD: lighting engineering.
SUBSTANCE: invention relates to lighting engineering. Light-emitting diode lamp has lower reflecting surface, (112, 212, 312, 412, 512, 612a/b, 712), a plurality of light-emitting diodes, (140, 240, 340, 440, 540, 640a/b, 740), a blocking reflecting surface (120, 220, 320, 420, 520, 620, 720), arranged above said light-emitting diodes (140, 240, 340, 440, 540, 640a/b, 740), a transmitting diffuser (30, 130, 230, 330, 430, 530, 630a/b, 730a/b), extending above blocking reflecting surface (120, 220, 320, 420, 520, 620, 720), through which LED light (140, 240, 340, 440, 540, 640a/b, 740), reflected inside, comes out of LED lamp. Said blocking reflecting surface (120, 220, 320, 420, 520, 620, 720) is located between lower reflecting surface (112, 212, 312, 412, 512, 612a/b, 712) and transmitting diffuser (30, 130, 230, 330, 430, 530, 630a/b, 730a/b).
EFFECT: high quality of mixing output colour.
