The invention discloses an LED lamp detection device. The LED lamp detection device comprises a device body, fixed frames, a fixed device and first fixed plates; supporting bases are fixed at the bottom end of the device body; a shell is arranged at the upper ends of the supporting bases; the fixed frames are mounted at the upper end of a conveying platform; a hydraulic cylinder is mounted at thetop end in the shell; a pressing plate is fixed at the lower end of the hydraulic cylinder; the fixed device is mounted between the fixed frames; fixed blocks are arranged in the fixed device; pulleysare mounted at the upper ends of grooves; the first fixed plates are mounted between the fixed blocks; second fixed plates are arranged at one ends of the first fixed plates; reset springs are mounted in the second fixed plates and the first fixed plates; and adjusting handles are arranged above the second fixed plates and the first fixed plates. According to the LED lamp detection device, the LED fixation is enhanced, so that the danger of falling during detection is prevented; and multiple LED lamps can be detected at the same time, so that the working efficiency is improved, and the time is saved.
