The invention relates to the technical field of illumination lamps, and aims to solve the technical problem that an
LED lamp which is accurate in light distribution, can meet illumination requirements of different places, and is more energy-saving and low in cost at the same time is provided. The
LED lamp comprises a light distribution device, a
heat transfer plate, a radiator and a casing, wherein the light distribution device is arranged on one side of the
heat transfer plate; the radiator is arranged on the other side of the
heat transfer plate; the light distribution device is covered with the casing and comprises a substrate, reflection cups and LED light sources; at least three reflection cups are arranged on the substrate; and one LED
light source is arranged at one end, facing towards the substrate, of each reflection cup, so that multi-
light source combined light distribution is formed. According to the
LED lamp, different beam angles and
light spot effects can be obtained by adjusting the arrangement and the quantity of the reflection cups, and the illumination requirements of the different places can be met. At the same time, a plurality of the reflection cups and the LED light sources are distributed in a separated manner, so that power and heat are separated, rapid heat transfer and heat
radiation can be realized, more energy is saved, and the
power consumption and the production cost are lower.
