Abstract: A light-emitting diode (LED) light fixture with a channel-type heat dissipation system is provided. The LED light fixture includes a plurality of light-emitting devices including LEDs, a heat dissipation unit connected with the plurality of light-emitting devices and having the plurality of light-emitting devices mounted thereon, a casing accommodating the heat dissipation unit and the light emitting devices, a cover connected with the casing, disposed above the plurality of light-emitting devices, and that is light-transmissive, and a ventilation channel through which ambient air passes. The casing has one open surface. The cover is connected to cover the open surface. The heat dissipation unit has an upper surface exposed through the open surface and a lower surface. The plurality of light-emitting devices are connected to the upper surface of the heat dissipation unit and exposed through the open surface.
