Light has board at angle in rail, LEDs attached to one side that radiate light essentially normal to board, LEDs on other side that radiate essentially parallel to board, transversely to row of LEDs

摘要

The device (10) has light emitting diodes (22,28) arranged in two parallel rows with the mean light radiation directions of the two rows at an angle of less than 180 degrees. The light is in the form of a rail from which the light of a row of LEDs on opposite sides emanates. A board (20) at an angle in the rail has LEDs attached to one side that radiate light essentially normal to the board and on the other that radiate essentially parallel to the board and transversely to the row of LEDs.
