LED strip light for shelf signboards

An LED strip light for shelf signboards, the shelf comprising at least one laminate which comprises one card board for setting the LED strip light for shelf signboards, characterized in that comprising:

• a strip-shaped lamp chamber and
• an LED light-emitting module disposed within the strip-shaped lamp chamber,
• on a cross-section perpendicular to the extending direction of the strip-shaped lamp chamber, the strip-shaped lamp chamber comprising a card board connecting edge for connecting the card board, a non-transparent edge spaced from the card board connecting edge, an upper transparent edge connecting the card board connecting edge and the non-transparent edge, a lower transparent edge connecting the card board connecting edge and the non-transparent edge and spaced from the upper transparent edge, the upper transparent edge being parallel to the laminate, the length of the card board connecting edge being less than that of the non-transparent edge, the LED light-emitting module which is provided on the card board connecting edge comprising at least one LED chip, and a strip-shaped reflective device arranged in the light emitting direction of the LED chip, on the cross-section perpendicular to the extending direction of the strip-shaped lamp chamber the strip-shaped reflective device comprising a first reflective surface and a second reflective surface and a boundary line between the first reflective surface and the second reflective surface, the first reflective surface reflecting all the light thereon toward the upper light transparent edge, the second reflective surface reflecting all the light thereon toward the lower transparent edge, the boundary line intersecting the optical axis of the LED chip.
