Abstract
An LED illumination apparatus includes a lamp housing, an LED module, distal covers and a light-transmitting hood. The lamp housing has a base, a heat sink at the top of the base, a heat dissipating channel between two adjacent heat sinks, and a receiving portion on an internal side of the base. The LED module includes a fixing base, a lampshade on a side of the fixing base, a plurality of LED lamps in the lampshade, and a connecting portion on the fixing base and coupled to the corresponding receiving portion. Each distal cover seals the front and back of the lamp housing, and the light-transmitting hood is connected under the lamp housing, and a containing space enclosed by the lamp housing, distal cover and light-transmitting hood for installing the LED module. The invention can simplify the manufacturing processes and reduce the material cost and development time.
