Light source assembly for shadowless lamp and shadowless lamp having same

Abstract

The invention discloses a light source module for a shadowless lamp and the shadowless lamp with the light source module. The light source module comprises a lampshade, at least one lamp, a fixing frame, a pull rod seat and a pull rod, wherein the lampshade comprises at least one lampshade body, the inner surface of each lampshade body is a reflecting surface, and each reflecting surface is a curved surface. The lamps are arranged in the lampshade and are in one-to-one correspondence with the lampshade bodies respectively, and each lamp is located on the focal point of the corresponding curved surface. The lamps are fixed to the fixing frame. The pull rod seat is arranged on the fixing frame. The pull rod is connected to the pull rod seat. According to the light source module, the effective utilization rate of light sources is ensured, the lamps and the lampshade can rotate along with the rotation of the pull rod when the pull rod is rotated so that it can be ensured that the lamps are located at the focal point positions of the curved surfaces, and thus the position of light can be synchronously and accurately controlled. The light source module is simple in structure, convenient to install, high in consistency of the illumination effect and good in using effect.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a light source assembly for a shadowless lamp and a shadowless lamp with the same. Background technique [0002] There are two main lighting structures of traditional surgical shadowless lamps: the first is the halogen lamp with reflector structure, which involves the fixed structure of the reflector, the fixed structure of the filter and the fixed structure of the light source. Due to the fixed structure of the light source The structure and the fixed structure of the reflector are two structures. After installation, the light source needs to be manually adjusted to accurately reach the focus position of the reflector. When the light source is fixed by the focusing structure, it is easy to cause the light source to deviate from the focus position of the reflector. The lighting effect provided by the group light source is poor in consistency, and the use effect is poor. The seco...

[0002] There are two main lighting structures of traditional surgical shadowless lamps: the first is the halogen lamp with reflector structure, which involves the fixed structure of the reflector, the fixed structure of the filter and the fixed structure of the light source. Due to the fixed structure of the light source The structure and the fixed structure of the reflector are two structures. After installation, the light source needs to be manually adjusted to accurately reach the focus position of the reflector. When the light source is fixed by the focusing structure, it is easy to cause the light source to deviate from the focus position of the reflector. The lighting effect provided by the group light source is poor in consistency and the use effect is poor

The second is the LED lighting structure, that is, the light source directly forms a light spot through the refraction of the lens. Although the light spot of this type of structure can be better controlled, however, if you want to change the position where the light source converges, you need to move the entire lamp head, and it is not efficient and accurate enough.
