Abstract: The present invention provides a solid state illuminating apparatus comprising at least two metal structures with heat dissipating fins, a lamp housing, at least one solid state light emitting device and a driver. The metal structures are configured to stack in the center of the lamp housing. The solid state light emitting device is configured to be located on the metal structure. The driver is configured to be located in the center of the metal structures.

Abstract: A wide-angle light emitting diode bulb comprises a LED chip module, a LED driver component for provide power, and a lamp cup for housing the LED chip module and the LED driver component. Main portion of light emitted from the LED chip is through the lamp cover out but a portion of LED light is scatted by the diffused powder on the lamp cover and through the apertures at the lamp cup out to light the ceiling when the LED bulb lit. The diffused powders are in-situ doped during manufacturing the lamp cover. The apertures are hided at the cabin-shaped recesses of the lamp cup.
