  • Patent number: 9562651
    Abstract: A lighting apparatus comprises: an LED module; a heat sink releasing heat generated by the LED module; and a light source supporting body having a locking part locking to the heat sink so as to hold the LED module on the heat sink. This avoids the necessity of screws used for attaching the LED module to the heat sink, and hence reduces the number of components and realizes easy attaching work for the light source. Thus, workability is improved in comparison with the conventional art.
