Double reflector housing

This creation is about a surgical luminaire, especially for a surgical luminaire with a double reflector.

Nowadays, technology is more and more developed, modern people are getting longer and longer, and the average age is gradually rising. Thanks to the development and progress of medical technology, now, in addition to the cultivation of medical personnel, the updating and research and development of medical equipment It is also a constant effort. In order to cooperate with the current technology, we will further create medical equipment that matches today's technology, so that medical personnel can use medical equipment more smoothly, which can increase safety and success rate when treating or performing surgery on patients.

The main target of hospital lighting is the patient, and the lighting needs are different for different conditions of the patient. For example, the operating room is where the doctor operates the patient, so the lighting requirements are high: high illumination (illuminance), high color rendering index, and shadowless are the basic requirements of the surgical lamp. .

The light source required for medical treatment can be roughly divided into three major purposes: illumination, diagnosis and treatment, and each has its own specifications according to different purposes. The light source required for the surgical light must have a color rendering greater than 85 and be luminescent. The LED itself is a cold light source, and its light source life and efficiency are superior to those of conventional halogen lamps used in surgical lamps and reduce the use of UV-IR filters. In addition, the light-emitting angle of the LED single package can be light-designed to obtain a small angle of light, thus reducing the ease of design of the optical system and improving the light use efficiency of the illumination system.

It is generally known that the surgical light is designed to utilize a high-intensity LED light source to achieve an illumination of 13-16 million lux over a detection surface of one meter, with a detection surface range of 30 × 30 cm ^ 2 . The color rendering is greater than 90 under white light, and its color temperature range is required to be between 3500-5000K, controlled by the LED drive circuit.

At present, according to the conventional surgical lamp, there is often a phenomenon that the medical staff can make the shadow of the scalpel and the hand because of the projection relationship in the scalpel, hand or head of the medical staff during the operation. The shadow of the part and even the shadow of the head will be projected on the part of the patient's operation, which will affect the visual line of the medical staff. The operation method can be large or small, with ordinary simple external resection, or a difficult brain. Precise surgery such as the heart or internal organs, and when performing difficult surgery with high difficulty, it requires the precise operation of the medical personnel and the rapid determination of the life characteristics of the person, etc., if the operation of one person is a negligence or a The fallacy is likely to cause regrets for human life. In addition to the high technical requirements for the operation of a medical staff, the precision requirements for surgical equipment cannot be ignored.

In order to produce a shadowless effect, it also solves the problem of medical personnel in the process of opening the knife. The resulting cephalometric and hand shadow are projected on the patient's cutting part, which affects the line of sight. Therefore, it is required to improve the use of the light, and the most commonly used light to solve the problem. The structure is a small-sized mirror and a lamp base structure, and a plurality of small mirrors and a bulb are used to emit cylindrical light of equal diameter from different directions and are focused on the same plane; and a conventional surgical shadowless lamp structure is generally used. The luminaire emits a light source and reflects the light source downward by using a reflector. However, this technique generally does not take into account the depth of the illumination, and only considers the angle and range of the illumination, and cannot effectively achieve the depth illumination, and the light source is relatively incapable. The effect of reaching a long distance of illumination.

Therefore, the present invention is only for the illumination and the angle of the illumination device, and the present invention is a dual-reflection surgical lamp, the main structure of which has a light source device, an external reflector and an inner cover. a reflector, the light source device uses the inner reflector and the outer reflector to have two different reflecting surfaces, so that the reflected light has two different reflection angles, and the light source device of the present invention uses the reflection method to make the light source portion Irradiating to the outer reflector and irradiating the other part to the inner reflector, the light source irradiated on the inner reflector has a small angle of light emitted by the light source, has a deep cavity effect, and is irradiated to the external reflection The light source on the surface has a large angle of light reflected to achieve a shadowless illumination effect, and the external reflector and the inner reflector are complementaryly irradiated, and the simple design of the structure can achieve a better effect of the surgical lamp. The deep cavity and shadowless effect that can be presented is better, and this is a novelty and progressive creation.

The main purpose of the present invention is to provide a surgical luminaire with a double reflector, which uses a reflector to illuminate the light source in a light-reflecting manner to produce a deep cavity illumination effect.

The secondary purpose of the present invention is to provide a surgical luminaire with a double reflector, which uses a reflector to illuminate the light source in a light-reflecting manner to produce a shadowless illumination effect.
