New description: [New technical field] This creation is about a medical lighting fixture', especially for a surgical light that uses a light guide to guide light and focus on different positions. [Prior Art] Surgical lamps are very important medical equipment during the operation. It is very important to provide perfect lighting functions for general Lu surgery. In addition to allowing the doctor to see the environment surrounding the surgery, including the surgical instruments and position, the monitor, and the internal conditions of the patient, including the clarity and color between the blood vessels and organs, etc., can also avoid serious damage due to lack of visibility. Medical negligence. Surgical lamps used in medical procedures need to have the characteristics of a shadowless area, which is different from a general lighting device. In the design of conventional surgical lamps, due to the use of a single light source, it is easy to cause problems such as insufficient illumination, which causes unnecessary troubles and problems for the doctor during the operation, such as unclear vision of the surgical position and incorrect position of the surgical instrument. Or inconvenient, need to constantly adjust the Li screen (four) to solve the problem, which caused great trouble to the operators. In addition, there are multiple light sources in combination with the mirror, the reflective layer and the light-transmitting mirror. The light source is collected in a single-:!, point position. However, this method also makes the focal depth of the surgical light insufficient. It is quite inconvenient to adjust the height position of the surgical light. [New content] However, in addition to the direct light guided by multiple light sources, the conventional surgical light has its main disadvantage in that it only focuses on the single-twist position. If the object to be illuminated is 3 M442449 i. i is sufficient (four) degree of exemption, it is necessary to adjust the hand to make the hand, which makes it quite inconvenient. Therefore, one of the purposes of the present invention is to provide a surgical light comprising: a light guide plate. The light guide plate is a plate body and defines a light source incident surface, a reflective surface and a light exit surface. Forming a plurality of reflective structures thereon; a plurality of LED lights corresponding to a predetermined position of the light source disposed on the light guide plate of the ship; wherein the light emitted by the plurality of LED lights enters from the light incident surface of the light guide plate and guides in the same direction Reflecting through the reflective structures on the reflective surface and emitting from the light exiting surface to focus on a plurality of focal points of different heights respectively to form a focal depth, so that an object at any height within the focal depth can obtain sufficient illumination brightness. Preferably, the plurality of reflective structures are circular steps formed by the center of the reflective surface of the surgical lamp from the inside to the outside. Preferably, the light source incident surface is a side surface of the light guide plates. Preferably, the reflecting surface is a top surface of the light guide plate. Preferably, wherein the central position of the surgical light forms an opening. Preferably, a plurality of optical elements are disposed between the incident surface of the light source and the plurality of LED lamps. Preferably, the light guide plate is integrally formed or assembled from a plurality of pieces. Sufficient illumination can be obtained by placing the object in the focal depth range formed by the surgical light through the creative technique.

Light that diverges at an angle (nearly parallel). . The light emitted by the plurality of LED lamps 21 and 22 enters from the light incident surface of the light guide plate and is guided in the same direction, and is reflected by the reflective structures 12 on the reflective surface 1U and is emitted by the light exit surface 2 to be respectively focused on a plurality of different heights. The focal points FI, F2, F3, and F4 form a focal depth d, which is defined as a focusable area A, so that an object of any orientation within the focal length D can obtain sufficient illumination brightness. In the present embodiment, the plurality of reflective structures 12 are circular structures formed by the inner and outer positions of the reflective surface 111 of the surgical lamp 1 , each of which has a predetermined interval, depth and The angle of the bevel so that the incoming light can be focused at different locations. The spacing between the various circular step structures may be equidistant or depending on the situation. _ is a different distance, and the angle of the bevel may be different depending on the position to be focused. Here, although the circular structure is taken as an example, it is not limited to This can also be a symmetrical polygonal structure. In addition, the incident surface 丨〇 of the light source in the embodiment is the top surface of the light guide plate i, and the plurality of LED lamps 21 and 22 are disposed adjacent to the incident surface 10 of the light source, that is, the side surface of the light guide plate 1 is preferably a ring array. The settings (or other geometrically symmetrical arrangement settings are also possible), and only two LED lights 21, 22 are exemplified in the figure. The LED is a light-emitting diode, including various types of light-emitting diodes that have been developed at present, and LEDs of different color temperatures can be installed in actual use to reduce the generation of colored shadows.
