Abstract: LED lamp including a plurality of light guide substrate, a mounting seat, an LED lamp panel positioned on the mounting seat and having at least on LED facing an incident surface of the light guide substrate, and a diffuser enclosing the light guide substrates. Each one of the light guide substrate feature a notch configured such that the light guide substrate are coupled transverse to one another by the notches, and further include a plurality of diffused reflection elements for extracting light from the light substrate.

Abstract: The present invention discloses an LED lamp comprising a light guide plate. The lamp comprises a mounting seat, an LED lamp panel and at least one light guide substrate, wherein the light guide substrate is provided with an incident side wall corresponding to the LED light-emitting unit, and the light guide substrate is at least provided with a side wall intersecting the incident side wall, which has one or more continuous or discontinuous diffuse reflection points. Light exits from the light guide substrate through the diffuse reflection points or particles. The diffuse reflection points, and thus the pattern of emitted light, can form complex or decorative patterns, or can be random.
