(54) LED LAMP


(57) An LED lamp has an LED device (10) and a lamp base (50). The LED device (10) has LED chips (11), conductive substrates (12), a packaging layer (13) and a protective cover (16). The conductive substrates (12) are arranged at intervals. Each LED chip (11) is supported by and electrically connected between two adjacent conductive substrates (12). The packaging layer (13) covers the LED chips (11) and a part of each conductive substrate (12) . The protective cover (16) covers the LED chips (11) and the conductive substrates (12) to form an LED device in a specific shape. As the LED chips (11) are close to the protective cover (16), thermal energy generated by the LED chips (11) is dissipated into the air to improve heat dissipation. The LED device achieves a continuous uniform lighting effect by a proper arrangement of the LED chips (11).
