Patent ID: 8496349

Claim:
A uniform light emitting lamp structure, having a lamp holder, an electric connection portion and a planar portion disposed on both end surfaces of the lamp holder respectively, a circuit board installed on the planar portion, and electrically coupled to the electric connection portion, and the lamp structure comprising: an LED light source, including a first light source, arranged at a central position of the circuit board; a lamp cover, installed at the periphery of the planar portion of the lamp holder for covering the LED light source; a light guide column, being a column structure with a refractive index n 1 , and having a critical plane and a containing portion disposed on both end surfaces of the light guide column, and the containing portion being provided for covering the first light source, such that after a light emitted from the first light source is incident at the light guide column through an environmental medium of a refractive index n 2 , a portion of the light is exited from the critical plane in a direction corresponding to the lamp holder to the environmental medium through a refraction and a reflection; wherein the uniform light emitting lamp structure further comprising a plurality of support wings installed on the critical plane and distributed radially outward, and each support wing having a light exit plane at an end of the support wing, and the light exit planes are disposed in a direction corresponding to the lamp holder; wherein the LED light source further includes a second light source surrounding the first light source and installed on the circuit board; and wherein the second light source is arranged at a position alternately with the support wings, such that the light emitted from the second light source will not be blocked by the support wings.
