Patent number: 7234855Abstract: A lamp having a planar light-emitting source includes a light-guiding structure, a light-emitting portion, and a shading supporting seat. The point-shaped lighting units of the light-emitting portion emit the point-shaped light beams toward the side plane of the light-guiding structure. Then, these beams enter the light-guiding structure. After turning approximately 90 degrees, a uniformly distributed planar light generated from the light-emitting plane of the light-guiding structure. So, a planar light source is obtained. In this invention, it has a planar light-emitting function with better lighting efficiency. The planar lighting is evenly distributed without shadow. Its energy consumption and heat generation are low. The product's life is prolonged.
