An LED light bulb having a light-shielding structure, comprising a bulb base (1), a transparent cover (2), a sensor (3), and a light-shielding barrel (4). The transparent cover (2) is fixed on the top part of the bulb base (1). The lower end of the light-shielding barrel (4) is fixed on the bulb base (1), while the upper end extends towards the transparent cover (2). The sensor (3) is arranged within the light-shielding barrel (4). The light-shielding barrel (4) is capable of effectively preventing the light emitted by the LED light bulb from irradiating onto the sensor (3) either directly or after being refracted by the transparent cover (2). The light emitted by the LED light bulb is prevented from being received by the sensor (3), thus preventing misoperation, and improving accuracy and sensitivity. |
