A light bulb apparatus includes a bulb shell, an antenna, a driver, a light source plate and a bulb cap. The light source plate has a first layer and a second layer. The LED module is disposed on the first layer. The second layer includes a metal portion. The metal portion carries heat generated by the LED module for heat dissipation. The antenna is disposed upon the first layer. A bulb cap is connected to an external power. The driver is electrically connected to the antenna for receiving a wireless signal. The driver converts the external power to a driving current supplied to the LED module.

A pluggable lamp includes a light-emitting tube body, a lamp head and a lamp seat provided at two ends of the light-emitting tube body. The light-emitting tube body includes a heat-dissipating member, a light-emitting plate and a light-transmitting cover. A first mounting groove is opened on one side of the heat-dissipating member. The light-emitting plate has a bottom side overlapped against a groove bottom of the first mounting groove. At least one lamp head pressing element is provided on one side of the lamp head facing the light-emitting tube body, and at least one lamp seat pressing element is provided on one side of the lamp seat facing the light-emitting tube body. The lamp head pressing element and the lamp seat pressing element abut against the top side of the light-emitting plate adjacent the lamp head and the top side of the light-emitting plate adjacent the lamp seat, respectively.

The present invention relates to a lighting device including a light transmittable shell, a conductive unit and a light source. The light transmittable shell has an inner space and a mounting opening connected to the inner space. The light source is mounted around the mounting opening such that the LEDs in the light source are arranged along the edge of the mounting opening. The light from the light source transmits through the light transmittable shell from the edge of the mounting opening, leading to a glowing effect of the light transmittable shell, improving the lighting efficiency of the lighting device. Furthermore, the LEDs are distributed along the edge of the mounting opening and have direct contact with the flowing air in open space, so the heat-dissipation of the LEDs is effective enough without extra cooling components.
