The second elliptical curved surfaces O21 and O22 have the same curvature, so when the second elliptical curved surfaces O21 and O22 have the first focal point f1 overlapping each other, the second focal points f2b and f2c also coincide with each other, and the second The curvatures of the elliptical surfaces O21 and O22 are different from the central elliptical surface O1, so the second focal points f2b and f2c do not coincide with the second focal point f2a; in addition, the second elliptical curved surfaces O23 and O24 also have the same curvature. Therefore, the second focus points f2d and f2e are coincident with each other, and the curvatures of the second elliptical curved surfaces O23 and O24 are different from the central elliptical curved surface O1 and the second elliptical curved surfaces O21 and O22. Therefore, the reflective lamp of the embodiment has Three second focal points f2a, f2b(f2c) and f2d(f2e) at different positions, the second focal points f2a, f2b(f2c) and f2d(f2e) at different positions are arranged in a straight line, which is just the lampshade a center line, and the inner surface 111 is closely adjacent to the second focus f2a, the second focus f2b (f2c), and the second focus f2d (f2e), and the horizontal plane s includes the second focus f2a Parallel ground.

According to the geometric principle of the ellipse, the ellipse has two focal points, and one of the focal points places a light source. After the light is reflected by the curved surface of the ellipse, the light passes through another focus, so that the light is concentrated on the other focus, and the light is emitted by the other focus. Therefore, the illuminating member 3 is placed at the first focus f1, and when the light emitted by the illuminating member 3 is incident on the central elliptical curved surface O1, the reflected light is concentrated on the second focus f2a, and the second focus is The direction of f2a continues to advance. Similarly, when the light hits the second elliptical surface O21 or O22, it gathers at the second focus f2b or f2c, and when the light contacts the second elliptical surface O23 or O24, Will be concentrated in the second focus f2d or f2e.

Since the second focus points f2a, f2b(f2c) and f2d(f2e) are located at different horizontal positions, the light emitted by the single illuminating member 3 can be reflected by a plurality of the elliptical arc surfaces O. The light emitted by the illuminating member 3 is concentrated on the first second focus f2a, F2b (f2c) and f2d (f2e), through the second focus f2, illuminate the light to the surgical position, thereby producing the effect of a plurality of light sources, and providing sufficient illumination brightness of the objects at different height positions. Therefore, when the user uses the reflective illuminator and performs surgery at a level lower than the horizontal plane s, it is possible to prevent the shadow from being generated by blocking the light in a single direction, thereby achieving a shadowless effect.

In summary, the reflective lamp of the present invention is provided with the reflective film r and the lamp cover 1 having a plurality of elliptical curved surfaces O, which can reflect and focus the light emitted by the single illuminating member 3 at different positions. The second focus f2a, f2b (f2c) and f2d (f2e) make it difficult for the light to be shaded by the foreign object, so that the single light-emitting member 3 can be used to achieve a shadowless effect. To achieve the effect of saving the cost of setting the reflector lamp; on the other hand, the reflection lamp can reduce the number of the light-emitting members 3 used, thereby achieving the effect of complying with environmental trends.
