Abstract:
1. An optical cavity structure of an LED lighting apparatus, comprising: a base that is integrally formed as a unitary, elongate member; a light reflection structure integrally formed with the base; at least one LED module; a power supply; and a light cover; wherein an optical cavity is constructed by said base, said light reflection structure and said light cover altogether; and said at least one LED module is attached onto a second end of the base and received within said optical cavity; said light reflection structure comprises two light reflectors respectively and integrally formed on opposite edges of the second end of the base and each comprising an inside surface that defines a curved light reflecting surface facing an internal space of said optical cavity such that light emitted from said at least one LED module is reflected by said curved light reflecting surface of said light reflector in a converging manner so as to achieve enhanced luminance; said at least one LED module comprises a circuit board and a plurality of LED chips attached onto said circuit board; said circuit board is attached to said second end of said base and is electrically connected to said power supply; a first end of said base opposite to said second end is formed of an internal space; and said power supply is received in said internal space of the first end of the base and electrically connected to an external power source.
