Description

HEADLAMP SYSTEM

Technological Field

The present invention pertains to new Head Lamp System in which the head lamp is attached onto a camera. Operator wears the head lamp to increase intensity of illumination of the working space. In more detail, working space is illuminated with greater light when doctor performs surgery on patient or when dealing with parts of human body during surgeries that pertain to narrow and deep areas. Moreover, the present invention pertains to the Head Lamp System, used for the filming of surgery, at the same time when the surgery is underway. The utility value of the above mentioned Head Lamp System is not limited merely to the instance whereby doctor performs surgery on patient. Instead, the present invention is equipment that may be used in all tasks that require better illuminated working space.

Background Art In the past, inducement of sufficient level of light was difficult since the light source of the

Head Lamp used single light source when doctor performed surgery of narrow and deep areas. Moreover, working space was darkened by shadow, resulting from operator's hand or surgical tools. When surgeon wanted to film necessary scenes while performing surgery, filming was enabled with another camera, separated from the Head Lamp. In the above mentioned case, filming was performed from an angle different from that which pertains to the view of surgeon since camera did not have to block the view of surgeon. Moreover, existing Head Lamp required separate hand maneuvering to block electric current in order to turn off light on the Head Lamp when the light of Head Lamp was temporarily unnecessary during work execution. Moreover, among existing head lamps, there were instances whereby light was illuminated onto working space by receiving transmission of light, produced from external light source by using optical fiber in order to increase the amount of light illumination of light source. Another case is one where external power was used to receive electricity to radiate light source. In the above mentioned case, the line that connected the Head Lamp with the exterior became the factor that restricted the actions of the operator. Accordingly, objectives of the present invention are as follows. First, light source is dispersed into at least two so that they are arranged in a manner that they do not block the view of the operator at a location close to the operator's eyes.

Accordingly, total amount of light iUumination and surface area of radiation of the above mentioned light sources were increased to increase intensity of iUumination of the working space. Secondly, camera shall be arranged towards the direction that coincides with the irradiation direction of light source's light at a location that is close to the operator's eyes to enable the operator to film the working space from the perspective of the operation during the working process. Third, during situations when the light of the Head Lamp is not needed, simple hand maneuvering shall be leveraged to install the contact point that separated mutually to facilitate the blocking of the power supply into light source. Fourth, Head

Lamp shall be divided into main body and remote part, and only the essential parts shall be installed at the main body, worn on the head of the operator, so that the weight of the present invention shall be reduced. The remaining parts shall be installed at the remote part, and the said remote part shall be worn at the other parts of the operator's body or be installed at the outside, located afar from the operator, and the connection shall be enabled wireless to ensure increased convenience for the operator.

Disclosure of Invention

To achieve the above mentioned purpose, the present invention shall be explained, diving Head Lamp into; light source, camera, support, connecting part, worn part, and remote part.

First, light source is comprised of at least two units of light source and is attached onto the support after arranging it in a way that it shall not block the view of the operator at a location close to the operator's eyes. Single unit of light source is configured of the following; one light illumination part that is like Filament that produce light, and one Parabolic Mirror that is becomes parallel light when the light is reflected from the above mentioned single light illumination part. In general, to increase the intensity of illumination of the working space, the amount of light illumination of light source shall be increased or the parallel light of wide land mass shall be converged into the inside of the working space, if and when possible. However, since increasing the amount of light illumination of one single unit of light source ^definitely is difficult technology-wise, it is advised to increase the number of light into multiple to obtain sufficient amount of light illumination. Moreover, one advantage is the decrease in shadow when light source is arranged in a wide scope, dispersed and placed. In the case of medical Head Lamp, when the anatomical structure of the human body is considered, it is realistic to arrange within the area mass of radius of 5 cm at a location where the view of the operator is not blocked. Second, camera shall be attached onto the support at a location close to light source so that the irradiation direction of the light source's light corresponds accordingly. Thirdly, support shall be attached onto light source and camera when it pertains to the front direction, and at the rear, connecting part and the hinge shall be adhered. Parts that come into contact with the connecting part shall be connected with power supply or contact point of the support that is used for blockage shall be installed. Fourth, connecting part is comprised of the front part of the main body of the connecting part and the Press of the rear side. Main body of connecting part is united with the support at the front, using a hinge, and shall be fixed on worn part towards the side of both sides. At the lower part of the main body of connecting part, the above mentioned is united with the Press with a hinge. At the point in which the main body of connecting part and support come into contact, there is connecting part front contact point that respond to the contact point of the support. Moreover, there are connecting part rear contact point and contact point of Press at each of the rear surface of the main body and the frontal part of the Press. Electricity can flow only when the above mentioned two contact points come into contact. Fifth, worn part is the part that is worn on the operator's head, and it is connected to the connecting part of the main body while at the front, and there is input/output terminal of the worn part at the rear. Needless to mention, it is possible to connect battery or charged battery to the above mentioned worn part input/output terminal. Sixth, cable that connects each unit of light source up to camera after passing through the contact point from the worn part input/output terminal is installed to supply electricity and transmit information.

Head Lamp remote part is comprised of the following; remote part input/output terminal that connects to the worn part input/output terminal, controller that controls Head Lamp's light source and camera's movement, power supplier that supplies power to Head Lamp's light source and to the camera, image storing device that stores filmed image from Head Lamp to the camera, transmission device that transmits the filmed image to the image marking device, located at the outside, from the camera of the Head Lamp, and so forth. The above mentioned remote part is worn on other parts of the body expect for the head of the operator where by worn part of the Head Lamp is worn. Sometimes, all the devices included in the remote part are not worn at the parts of the operator's body. Instead, as in the case of image marking device, they may be attached onto the exterior that is detached from the operator.

Hereafter, the optimal example of execution pertaining to the present invention shall be explained, using figures. Light source ( 1 ) on Figure 2 is comprised of 4 units of light source entity, gathered together.

One single unit of light source entity is comprised on one light iUumination part and one Parabolic Mirror, and the above mentioned light illumination part is situated at the focus point of the above mentioned Parabolic Mirror, which creates parallel light when the light, produced from the above mentioned light illumination part is reflected against the Parabolic Mirror. 4 units of light source entity are in the same distance from the central axis of light source. Among the above mentioned unit of light source, there is a space near the central part of light source so the operator can see the working space through this space. Light that is projected from this unit of light source (11) is converged near or close distance in terms of sight according to the focus adjustment device, drawn in detail on Figure 3. Accordingly, the present invention illuminates the working space. Figure 3 shall be leveraged to explain the process of adjusting the focus on light source. In that case, each light source's inner side U-shaped hook (12) and U-shaped hook at the outer side of light source (13) are attached onto the 4 units of light source entity (11). U-shaped hook of light source of the inner side is united via hinge with fixation device U-shaped hook(15) that projects from the fixation device (16). U-shaped hook at the outer side of light source is united with the connecting rod (14) via hinge. At the front of the light source fixation device (16), fixation device U-shaped hook (15) is projected to the level of amount of unit light source, and it is attached to the support (3) at the rear. Light source fixation device (16)'s external surface (A) is formed into screw. Thus, it is united with the screw that is formed on the inner surface (B) of the focus controlling device (19). Moreover, connecting rod (14), that is united with the U-shaped hook at the outer side of light source (13) by using hinge, is again united with hinge with the U-shaped hook (17), projected from the controlling ring (18). At the inner side of the controlling ring, projection (181) is formed, and it unites with the groove (191), formed at the outer surface of the focus controlling device (19). Controlling ring (18) when it pertains to focus controlling device (19), enables circulation movement in relative terms. If and when the process of operating the focus adjustment device from Head Lamp's light source, support is attached to the rear of the light source fixation device (16). At a time when focus controlling device (19), controlling ring (18), and unit light source are united, when the focus controlling device (19) is circulated after using the central line of the device as the axis, then the focus controlling device (19) starts off spiral movement due to the screw, formed at the inside of focus control device and at the outer side of light source fixation device (16). Based on the above mentioned spiral movement of the focus controlling device (19), controlling ring (18) engages in straight line movement towards the front and rear directions, and this type of controlling ring's straight line movement goes through the connecting rod (14) to get transmitted into light source's light outer U-shaped hook (13). At the end, each unit of light source engages in circulation movement towards the center axis of light source, using the hinge based union part of the light source's light inner side U-shaped hook as an axis. Due to the circulation movement of this unit of light source, light disseminated from each unit of light source is converged at near or far distance. The above mentioned type of focus adjustment method is merely one example. There are many other methods. Moreover, this example is based on the assumption that there are 4 units of light source, and that each unit of light source is at the same distance from the central axis of light source. However, the above mentioned example is not the only method. In other words, it is possible to unite greater number of unit light source to create light source. Moreover, there is no need for the distance from the light source axis to each unit of light source to be the same. However, in any case, light source shall not block the view of the operator. In the case of Head Lamp for medical use, when the anatomical situation of human body is taken into consideration, it is recommended to place unit light source at a location that is within radius of 5cm so that the view of the operator is not blocked. This light source can increase the total amount of light illumination, compared to the case when there is single umt of light source. Since unit light source is dispersed, less shadow is created due to the effect of shadowless(operating) light. For the reasons mentioned above, the present Head Lamp is highly resourceful when doctor performs surgery on narrow and deep parts of the patient's body. Like light source (1), camera (2) shall be attached onto the support (3) to film the working space, illuminated by the light disseminated by light source. As for the location whereby the camera shall be attached onto the support shall be near light source and shall be at a place whereby the view of the filming is not blocked by hght source. At the same time, the location shall be set at a place that does not block the view of the operator. On the present actual example, camera was attached onto the point where the central axis of light source meets the support. However, in other examples, camera shall be attached at sites that are different from those where the support is attached, and the camera shall be attached in the same direction as hght source. At the above mentioned site, telescope or magnifying glass shall be attached to benefit from expanded view of the working space when the operator wears the Head Lamp to perform task. Support (3) shall fixate light source (1) and camera (2) towards the front. At the rear, the above mentioned shall be attached with the connecting part (4) through horizontal axis (31) by using hinge. Parts of the area that come into contact with the connecting part shall be installed with support contact point (32). Circulation movement of Support on vertical surface is enabled due to the connection of the above mentioned with the connecting part, using hinge. Support contact point (32) is installed at a location where it confronts the connecting part front contact point (not figured) that is situated at the connecting part. Only when these two contact points come into contact, electric connection is enabled, which supplies electricity to light source and camera. In other words, only when the support (3) is at the location, depicted on Figure 2, that is, when light source and camera are heading towards the working space at the front, can the two contact points come into contact. If and when, light source's light is not necessary, then the operator may circulate the support towards the upper part. Accordingly, support contact point (32) and main body of connecting part contact point are mutually separated and the supply of electricity to light source and camera is discontinued. Connecting part (4) shall be comprised of main body of connecting part (41 ) at the front and of the Press (42) at the rear. Main body of connecting part (41) is united with the support (3) at the front, using a hinge. On the side of both sides, the above mentioned is fixed onto the worn part (5), and shall be united with the Press (43), situated at the lower part of the main body of connecting part (41) by using hinge. At the main body of connecting part (41), connecting part front contact point (not figured) that confronts the support contact point (32) is at the parts of the area that comes into contact with the support. Moreover, at the rear surface of the main body of connecting part and the front of the Press, there are connecting part rear contact point (not figured) and contact point of Press (43) at a part where both confront each other. Connecting part rear contact point and contact point of Press are separated mutually by the spring, however when the operator wears the Head Lamp on the head, the forehead of the operator presses down on the Press, and the above mentioned two contact points come into contact. At the end, when the operator wears the Head Lamp on the head, and at the same time when Head Lamp's light source is headed towards the front, electricity is supplied to hght source and camera. Worn part (5) is the area that comes into contact with the head of the operator when it pertains to the Head Lamp. At the front, the above mentioned fixates the main body of connecting part (41), and the rear, the above mentioned includes the worn part input/output terminal (51). The above mentioned worn part input/output terminal (51) may connect to battery or to the rechargeable battery, and the above mentioned may connect to the remote part input/output terminal that is located at the remote part to get power supply from the remote part. Information may be transferred between the above mentioned two input/output terminals.

Moreover, cable is connected from the worn part input/output terminal, going through each of the contact points to reach up to hght source and camera. Therefore, power supply and transfer of information are enabled between the above mentioned.

Head Lamp remote part (6) shall include the following; remote part input/output terminal that is connected to the Head Lamp worn part input/output terminal, controller that controls the operation of the Head Lamp, power supply device that supplies power to the Head Lamp, image storing device that stores filmed image on camera, transmission device that transmits camera's filmed image to the image marking device (7) that is distanced from the operator, and others. The above mentioned remote part may be worn in other parts of the body besides the head of the operator where the main body of the Head Lamp main is worn on. As for the method of applying remote part, there are; method of hanging on the neck of the operator, method of hanging down from the shoulder as if back pack, method of wearing on the waist and so forth. Needless to mention, at times, it is possible to not to apply all the devices that are included in the remote part onto the body of the operator, instead, the above mentioned devices may be attached to the exterior along with the image marking device to exchange information through wireless means.

Industrial Applicability
