Abstract

The utility model discloses a light emitting chassis which comprises a chassis and an LED (Light Emitting Diode) light source arranged on the chassis, wherein the LED light source consists of a plurality of sectional base plates and LED chips arranged on the sectional base plates; the sectional base plates are arranged and fixed on the chassis around the center of the chassis at intervals; and the sectional base plates are electrically connected through leads. The leads replace the parts of the original base plates without the LED chips, so that the base plate material can be saved; and the sectional base plates are arranged in square, so that the rough shape cutting corner waste is reduced compared with previous circular base plates. Plates output by rough shape cutting are more, so that the base material waste is reduced, and the cost is saved. In addition, the sectional base plates are obliquely arranged in the center of a bottom plate with the angle of inclination of 150-160 degrees, so that the light emitting efficiency is improved. Meanwhile, the light emitting angel is enlarged to maximally compensate the deficiency that the light emitting angel of the LED chips is small and enhance the light efficiency to the maximum extent. Central dark rings on the chassis can be eliminated.
