Abstract
A LED light bulb with a light-shielding structure is provided. The LED light bulb includes a bulb base (1), a transparent cover (2), a sensor (3) and a light-shielding barrel (4). The transparent cover (2) is fixed on a top of the bulb base (1). A lower end of the light-shielding barrel (4) is fixed on the bulb base (1). An upper end of the light-shielding barrel (4) is extended upwardly toward the transparent cover (2). A light-shielding element (8) is disposed within an inner hollow portion of the light-shielding barrel (4). A sheltering part (9) is arranged around the light-shielding element (8) for sheltering a portion of the light beam which is refracted to the light-shielding barrel (4) by the transparent cover (2). The sensor (3) is located at a center of the light-shielding element. By the light-shielding barrel (4) and the light-shielding element (8), the light beam emitted by the LED light bulb can be effectively prevented from being directly projected onto the sensor, or the light beam refracted by the transparent cover (2) can be effectively prevented from being projected onto the sensor (3). Since the light beam emitted by the LED light bulb is not received by the sensor (3), the possibility of causing the erroneous operation of the sensor will be minimized, and the sensing accuracy and sensitivity of the LED light bulb will be enhanced.
