LED illumination apparatus

1. An LED illumination apparatus, comprising:

an aluminum extrusion lamp housing, having a base, a plurality of heat fins extended upward from the top surface of the base, a heat dissipating channel disposed between any two adjacent heat fins, and a receiving portion formed on the bottom surface of the base;

a plurality of LED modules, each having a fixing base, a lampshade mounted onto a side of the fixing base, a plurality of LED lamps installed in the lampshade, and a connecting portion disposed on the fixing base for the LED module being coupled to the base through the receiving portion;

a pair of distal covers, for merely sealing and connecting both front and back sides of the base of the lamp housing respectively, the heat fins being exposed for heat dissipation;

a light-transmitting hood, coupled to the bottom of the lamp housing, so that a containing space is enclosed by the lamp housing, the distal covers and the light-transmitting hood for installing the LED modules,

wherein the receiving portion is formed as a T-shaped groove on an oblique board of the base for a screw bolt being slid therein, and the connecting portion has a through hole for the screw bolt passing through and a screw nut being engaged with the screw bolt to fix the LED modules on the base; and

a protrusion extended downward from an interval between two receiving portions, and a wire containing slot disposed at the middle of the protrusion.

2. The LED illumination apparatus of claim 1 , wherein the base of the lamp housing is substantially in an M-shape.

3. The LED illumination apparatus of claim 2 , wherein the base includes a channel disposed at the bottom of a sideboard of the base, and the light-transmitting hood includes two flat boards, and a groove and a through hole formed on each flat board respectively, and the groove is provided for installing a rectangular waterproof rubber strip, and the through hole is installed correspondingly with the channel, for passing and fixing a screw bolt and a screw nut.

4. The LED illumination apparatus of claim 1 , wherein the LED module further comprises a heat equalizer attached separately onto both upper and lower flat surfaces of the protrusion of the lamp housing and each LED lamp.

5. The LED illumination apparatus of claim 1 , wherein the base includes two corresponding penetrating holes disposed on the top of the base, and each distal cover forms a protruding ear, and the protruding ear has a through hole disposed thereon and corresponding to the penetrating hole, for passing and fixing a screw bolt and a screw nut.

6. The LED illumination apparatus of claim 1 , wherein each distal cover has an extending section protruded inwardly and to be inserted into the base.

7. The LED illumination apparatus of claim 1 , wherein the rear distal cover has a movable protecting cover disposed under the rear distal cover.

8. The LED illumination apparatus of claim 1 , wherein the light-transmitting hood is transparent or semi-transparent.

9. An LED illumination apparatus, comprising:

an aluminum extrusion lamp housing, having a base with a substantial M-shape in cross section, a plurality of heat sinks extended from the top of the base, a heat dissipating channel disposed between any two adjacent heat sinks, and a receiving portion formed on an internal side of the base;

a protrusion extended downward from an interval between the receiving portions, and a wire containing slot disposed at the middle of the protrusion;

a plurality of LED modules, each having a fixing base, a lampshade mounted onto a side of the fixing base, a plurality of LED lamps installed in the lampshade, and a connecting portion disposed on the fixing base and coupled to the corresponding receiving portion of the base, wherein the LED module further comprises a heat equalizer attached separately onto both upper and lower flat surfaces of the protrusion of the lamp housing and each LED lamp;

a set of distal covers, for sealing and connecting both front and back sides of the lamp housing respectively; and

a transparent or semi-transparent light-transmitting hood, coupled to the bottom of the lamp housing, and having a containing space enclosed by the lamp housing, the distal covers and the light-transmitting hood for installing the LED modules,

wherein the rear distal cover has a movable protecting cover disposed under the rear distal cover,

wherein the receiving portion is formed at a T-shape groove of an oblique board of the base, and the connecting portion is disposed at a through hole of the fixing base for passing and fixing a screw bolt and a screw nut,

wherein the base includes a channel disposed at the bottom of a sideboard of the base and the light-transmitting hood includes two flat boards, and a groove and a through hole formed on each flat board respectively, and the groove is provided for installing a rectangular waterproof rubber strip, and the through hole is installed correspondingly with the channel for passing and fixing a screw bolt and a screw nut,

wherein the base includes two corresponding penetrating holes disposed on the top of the base, and each distal cover forms a protruding ear, and the protruding ear has a through hole disposed thereon and corresponding to the penetrating hole, for passing and fixing a screw bolt and a screw nut, and

wherein each distal cover has an extending section protruded inwardly and to be inserted into the base.
