Abstract

The present invention relates to a shadowless reflector structure for an operation lamp. The operation lamp has a front lamp enclosure and a rear lamp enclosure, which are up-and-down sealed. The front lamp enclosure has an opening for ejection of the light. The upper portion of the opening is connected to a front glass. The lower edge of the reflector opening in the front and rear lamp enclosures is fastened to the front glass. The lower edge of the front glass has a handle. A socket of the light bulb is installed on the front glass. A heat-absorbing glass is installed around the light bulb. The reflector reflects the light received towards the front glass. The warp tangent lines in the warp direction of the reflector are formed by a continuous 360 degree rotation of more than two sections of base curve along the centering line of the reflector. Each section of base curve evenly reflects the light to the focal base plane. One end of the base curve in the reflector near the center of the reflector reflects the light to the circumference of the diameter of the focal circle on the same side of the end. The last section of the base curve near the outer edge of the reflector reflects the light to the circumference on the same side corresponding to the focal circle.

Description

498149 j No. 87 " Discussion V. Description of the invention (1) The present invention is a "shadowless mirror structure of a surgical lamp", especially a light source with a single bulb (blub) source, which is repeatedly irradiated to Mirror structure of the target area. In order to produce a shadowless effect, according to the conventional operation lamp, the head and hand shadows generated by the medical staff during the operation are also more resolved, which affects the sight of the patient. Therefore, the use of lighting is required to be improved. The most commonly used lighting structure is a multi-small reflector and a lamp cap structure. Several small reflectors and bulbs are used to emit cylindrical light with equal diameters from different directions and focus on the same plane. This structure, when When the distance between the lamp head and the cutting part needs to be changed, the distance between the reference plane of the polycondensation and the lamp head needs to be readjusted; it is necessary to adjust the IS of the individual light bulbs in use. Moreover, the structure of the multi-small reflector and the lamp head of the light bulb is more complicated and the cost Souther, heavier and less dexterous to move. m research found that a single large mirror-type lamp head of a light source =: two; the plan can solve the above-mentioned multi-small mirrors and bulbs side shouts. The first picture shows the basic structure of a most commonly used reflector-type lamp cap and its light; = The light emitted by the lamp ^ is reflected to a predetermined focus, and each of the-regions within it comes from only two non-κ Xiang == Ming Fanzhong Surgeon ’s head position 9 is close to the surgical lamp ^, and the part of the light 5 is blocked; coupled with the hand and "":, there is usually a need to configure a second or even The shadow caused by it is "strong". In addition to the shortcomings of the above-mentioned shadowless effect, it is still 498149 case number 87119103. V. Description of the invention (2) There is a light source wasted. A large reflector has a fixed lamp cap on the upper end. Use range. The straight part of the reflecting disc 7 uses the main cause of the brightness of the light bulb, and the conventional glass 8 produces a soft light transmittance approximation. In order to enhance the hand hair, a structure of the present invention is designed. " The centerline rotation line of the mirror is established by its phase to reflect these small planes while the mirror reflects a reference curve. The focal point of the reference plane bubble is extended by two sections of the local reference astigmatism effect, which makes it impossible to further improve the shortcoming. The basic structure of the lamp holder requires a disc-shaped portion 7 with a grip located below the center and direction of the lamp holder, so the invalid diameter ρ Υ of the reflector and light mirror is limited, as shown in the first figure, the diameter ρ X, and the invalid angle of the light source Α is also out of the light. 8 glasses in front of the surgical lamp. In order to eliminate the shape of the filament in the lighting range, a single large-mirror-type lamp head has the effects of and. However, this type has a wavy pattern at 50%, which greatly reduces the shadowless effect and lighting brightness of the lamp head in the lighting range. This kind of "shadowless mirror structure for surgical lamps" aims to provide a "nothing inside of surgical lamps" The curved surface can be formed by two or more segments of reference 360 °. In addition, it can be cut or intersected and orthogonal to the meridional section. The light rays around the centerline of the mirror every fixed angle can avoid the surgeon's head. The surrounding reflected light is in the same area uniformly at different angles to enhance the effective utilization of no shadow effect; many facets can also be established on the full curve of the mirror to lighten the hands and instruments more effectively in lighting Because of the knowledge sheet 6 and the effective use of the hand source to move the hand source, it must be larger than it can not be filled enough to reduce another to produce a uniform wavy pattern. The knot curve is formed around the reference curved facet using the reference curved facet. It can be combined with another irradiation to improve the shadow generated within the fixed angle range of the lamp circle and

498149 ------- Case No. 87119103 _ Birth month _ Amendment ___ V. Description of the invention ⑷ '— ^ As shown in the above structure, the features of the present invention are based on two reference curve bases, and are passed through a mirror 2 3 The meridional tangent in the longitude direction is composed of two segments of the reference curve 3 1 and 3 2 which are rotated and set around the center line of the mirror 360 °. As shown in the third figure, the first segment of the reference curve 3 1 Closer to the centerline area of the mirror, the second section of the reference curve 3 2 is closer to the outer edge of the mirror 'and the two sections of the reference curve have equal tangent slopes at the contact point 3 4; each section of the reference curve will come from the filament center 3 6 Directional light rays are sequentially and evenly reflected to the focal plane 3 7 between the two end points on the diameter of a circle with the center line of the mirror as its center 3 8; the starting point 3 3 of the first reference curve reflects the light to At the end point of the diameter and the same side, the connection point of the two reference curves 3 4 reflects the light to the other end point of the diameter and the opposite side '. From Figure 3, it can be found that the light is focused on the cylindrical illumination range in this section. Above '苐 the end point of a reference curve 3 5 It hits the end point with the same diameter as the diameter, and the light reflected by this segment is not focused. Among them, the light reflected from the first section of the reference curve 31 to the illumination range 30 can almost completely avoid the shadow of the head of the surgeon at 9 and effectively diminish the head shadow; and obviously, the invalid diameter of the mirror of the present invention is 0 Z For example, the diameter of the disc-shaped portion shown in the first figure is 0 X small, that is, less than the ineffective diameter of the conventional mirror 0 Y; from the foregoing inference, it can be seen that the ineffective angle B of the light source of the present invention is significantly smaller than the ineffective angle a of the conventional light source a . In this way, the effective utilization of the light emitted by the bulb can be improved; the illuminance within the lighting range of 30% can be improved. Except for avoiding the position of the physician's head during the operation, the light reflected by the first reference curve 31 range and the light reflected by the second reference curve 32 range illuminate the focus plane 37 uniformly at different angles. Within the area, also

Multiplied the shadowless effect. The mirror 2 3 of another preferred embodiment can be formed by using the two reference curves to form a plurality of facets 3 9 that are tangent or intersecting with each other and orthogonal to the meridional tangent plane. We can divide these facets 3 9 another mirror is formed around the center line of the mirror at a fixed angle; as shown in the fourth and fifth figures, the four sides of each small plane 3 9 are the same as the four planes above, below, left and right. Intersecting lines. In this way, a local astigmatism effect will be produced in the lighting range, which effectively dilutes the shadows produced by the hands and medical equipment. Therefore, the soft function of the wave-shaped front glass 8 is used. In this way, a flat front glass 2 4 (visible light transmittance can be used) Up to 95%) Wave generation can greatly increase the illuminance within 30% of the lighting range.
