Light-emitting diode lamp with adjustable light distribution curve

The utility model discloses a light-emitting diode lamp with an adjustable light distribution curve. A light-emitting diode is arranged below a radiator, a lampshade is arranged on the radiator on the outer side of the light-emitting diode, and an angle adjusting screw penetrates an angle adjusting fixed screw hole on a lamp holder and is connected with the radiator. The light-emitting diode lamp adopts the decentralized combination method, thereby not only facilitating the heat radiation, but also facilitating the installation, the combination way is flexible, and different powers and different shapes can be arbitrarily combined, thereby facilitating the design of the lamp. The light distribution curve is adjustable, thereby leading the lamp to be capable of playing the greatest efficiency according to the actual situation at the scene and saving the cumbersome and complex work of designing the optical characteristic curve of the lamp. Gaps are formed among the combination units, thereby not only reducing th
