| 摘要 |
The present invention relates to the technical filed of illumination, and provides an omni-directional LED light-emitting bulb, comprising: a cap (1), a housing (2), an Led light source (3), an LED drive device (4), a diffusion lampshade (5), and a plastic base (13). The plastic base (13) is disposed between the housing (2) and the cap (1); the housing (2) comprises a flat (2-2), and the diffusion lampshade (5) is provided on the whole flat (2-2); the LED light source (3) comprises a first LED light source (3-1) and a second LED light source (3-2); the first LED light source (3-1) is embedded at the inner side of the upper portion of the flat (2-2), and the second LED light source (3-2) is provided on the lower side of the flat (2-2) opposite to the back of the first LED light source (3-1); and a reflecting cup (6) is sleeved on the outer wall at the lower end of the flat (2-2), and a diffuse reflection surface (7) is provided on the outer wall of the reflecting cup (6) opposite to the lower end of the cup body of the reflecting cup (6). With this omni-directional LED light-emitting bulb, light beams diffuse towards all directions after being spread by the diffuse reflection surface of the reflecting cup and the diffusion lampshade, so that the emitting angle of the LED light source is greater than 270 degrees; therefore, the omni-directional light emitting effect is effectively achieved. |
