An LED illumination apparatus comprising:
- an LED substrate having a plurality of positioning holes, and an LED mounting face;
- a heat sink integrally formed with the LED substrate;
- a plurality of LEDs mounted on the LED mounting face;
- a plurality of housings disposed on the LED mounting face of the LED substrate correspondingly to the respective LEDs, each housing having a projection configured to be fitted in a corresponding one of the positioning holes, each housing further having a connecting part;
- a plurality of lenses, each lens positioned and fixed to a corresponding one of the housings;
- and
- a cover disposed over the LED mounting face, and configured to contact peripheral parts of a light emitting side of the lenses and of the housing, to hold them in position relative to the LED substrate,
- a recessed part is formed on a light entering side of the lens body, thereby allowing light from the LED to enter the lens,
- wherein the plurality of housings are connected to adjoining housings by the connection parts fitting between the positioning hole and the projection.
