The invention discloses a novel high power
LED lamp body comprising a
lamp shell and a light path heat dissipation combined
system. The light path heat dissipation combined
system comprises a base, a light path module, a liquid cooling and
air cooling heat dissipation module, a power source module, a driving module and a main control display module, wherein the light path module, the liquid cooling and
air cooling heat dissipation module, the power source module, the driving module and the main control display module are arranged on the base in sequence. The base is mounted inside the
lamp shell in the mode that the base can be pulled out and inserted along a guide rail, so that pull-inserting type connection of the
lamp shell and the light path heat dissipation combined
system is achieved. The liquid cooling and
air cooling heat dissipation module comprises a heat absorption device, a liquid cooling heat dissipation device, a fan, a plurality of liquid cooling pipelines and a
liquid circulation pump. The
liquid circulation pump, the heat absorption device and the liquid cooling heat dissipation device are sequentially connected through the multiple liquid cooling pipelines. The
LED lamp body can be widely applied to a high power LED imaging lamp and a spotlight. The novel high power
LED lamp body is compact in structure, convenient to overhaul, large in power, good in lighting effect, convenient to detach,
mount and overhaul, good in heat dissipation capacity and long in service life.
