An incandescent light lighting-emulating LED spotlight for use in illumination, comprising a cap (1), a plastic base (2), a power supply (3), a heat-dissipating body (4), an LED light source (5), and a front cover (6). The power supply (3) is fixed within the plastic base (2). One end of the plastic base (2) is fixedly connected to the cap (1), while the other end is connected to the heat-dissipating body (4). The LED light source (5) is fixed horizontally within the heat-dissipating body (4). A stippled lens (7) is arranged at the front end of the heat-dissipating body (4) relative to the LED light source (5). The stippled lens (7) comprises a first diffusing surface (7-1), an internal reflecting surface (7-2), a second diffusing surface (7-5), and a concave light convergence point (7-6) constituted by the first diffusing surface (7-1). The internal reflecting surface (7-2) consists of one or more orderly arranged light convergence protrusions (7-3) and reflecting curved surfaces (7-7). Also, an optical thin-film layer (7-4) is arranged outside of the light convergence protrusions (7-3) of the reflecting surface (7-2). The incandescent light lighting-emulating LED spotlight allows for multiple reflections and focusing of a light, thus allowing an emitted lighting to achieve a great illumination effect, while being a soft and comfortable light. |
