Description

An apparatus for optical irradiation for medical use with hybrid function

The present invention relates to a medical lighting device, and more particularly, a hybrid type that can be changed into three modules in one product so that it can be used in a surgical environment suitable for dental treatment, general treatment, or surgical mode according to a user's mode selection It relates to a medical lighting device.

In general, lighting lamps convert electrical energy into light energy so that objects can be identified even in dark places, and in recent years, they have been widely used to create interior decorations or cozy atmospheres.

Such lighting lamps are manufactured in various forms, and conventionally, lighting devices using incandescent lamps or fluorescent lamps have been mainly used. However, incandescent lamps are cheap to manufacture, but they generate a lot of heat in converting electrical energy into light energy, so their use is recently discouraged. It takes time and has a short lifespan.

In order to solve the above-mentioned problems, recently, LEDs (Light Emitting Diodes) that have a semi-permanent lifespan and can obtain high illuminance with low power have been developed. These LED devices have advantages such as fast processing speed and low power consumption, are environmentally friendly and have a high energy saving effect, so they are spotlighted as a next-generation strategic product.

In addition, the LED device consists of a junction of a p-type and an n-type semiconductor, and when a voltage is applied, the energy corresponding to the bandgap of the semiconductor is emitted in the form of light through the combination of electrons and holes. It is a kind of optoelectronic device. These LED devices have recently been developed with LEDs of various colors and can display natural colors, so they are applied to various places such as large outdoor electric signs, traffic lights, automobile dashboards, home appliances, neon alternative signs, medical equipment, warning and guidance lights. .

As shown in FIG. 1 , the lighting device for hospital treatment may be used as a lighting device 100 capable of illuminating a treatment area in order to simply treat a patient in a small clinic such as dentistry. That is, the lighting body 20 coupled to the support 10 is rotated left and right on the support 10 to treat or treat the treatment and treatment area with the LED light 24 mounted on the bottom of the lighting body 20. illuminate it so that

At this time, the lighting device 100 is formed in a rectangular shape by combining the movable lighting body 30 to which the LED lamp 31 is attached to the four corners 21 of the lighting body 10, and the slide bar 40 is removable while being removed. Since the lighting formed in the lighting main body 30 is focused on one place in a wide direction to illuminate, a shadow does not occur.

And, when you want to perform surgery such as implant and gum surgery, when you want to form a mute light so that a shadow by operators such as doctors and nurses does not occur on the surgical site, in the four corners 21 of the lighting main body 20 The combined movable lighting body 30 is separated from the corner 21 of the lighting body 20 to illuminate the surgical site.

That is, draw out the slide bar 40 inserted into the insertion groove 51 of the cross-shaped support 50 diagonally formed on the upper part of the lighting main body 20 to focus on one of the surgical sites so that it can serve as a non-yeongdeung. will become

In this way, the conventional lighting device for hospital treatment is used as a medical light by combining the lighting main body 20 and the movable lighting light main body 30 during treatment, and is movable at the corner 21 of the lighting main body 20 during surgery. The main body 30 of the lighting lamp can be separated and used as a non-yeong lamp, but since the slide bar 40 has to be manually drawn out, there is a hassle and inconvenience of having to attach and detach the movable lighting lamp, and it is difficult to secure accuracy and reliability according to the actual mode conversion. There is this.

In addition, there is a problem in that there is a risk that a patient may be cross-infected due to contact of an operator or a surgical assistant with foreign substances during operation of the medical lighting device.

Figure 2 is a bottom view showing the configuration of the hybrid-type medical lighting device 300 according to a preferred embodiment of the present invention, Figure 3 is a functional block diagram showing the control configuration of the hybrid-type medical lighting device 300 of Figure 2 .

First, referring to FIGS. 2 and 3 , the hybrid type medical lighting device 300 according to the present invention includes a light source module 100a, 100b, 100c, 100d, 100e, 100f, 100g composed of a plurality of LEDs, and the A light source module assembly (251, 252, 253, 254, 255, 256) in which a plurality of light source modules are configured based on the center of a circle, and a hybrid light source module (250) comprising the light source module assembly in a plurality of combinations; It is composed of a medical lighting head module 260 coupled to the hybrid light source module 250 and supported on a ceiling or a balance arm system through a connection part 240 . In addition, it may be configured by further adding a handle module 270 as a handle structure to be combined with the medical lighting head module 260 to adjust the vertical or left and right positions of the medical lighting head module 260 . Accordingly, the medical lighting head module 260 is fixed by being applied to the ceiling of an operating room or treatment room through the connection unit 240, or combined with a balance arm system (not shown) applied to a medical chair or a mobile medical device to be fixed. can In addition, by using the handle of the handle module 270, it is possible to freely position the medical lighting head module 260 as needed when treating a patient, move it conveniently, and place it at a desired position to be stably fixed.

At this time, the medical lighting head module 260 includes the light source module assemblies 251, 252, 253, 254, 255, 256 in which the LED light source module 100 is configured in plurality based on the center of the circle, and the light source module assembly. It may be composed of a hybrid type light source module 250 composed of a plurality of combinations, and a cover 261 that houses, structures, and protects the hybrid type light source module 250 .

For example, in the present invention, six light source modules 100 may be configured in a radial structure based on the center of the circle, with the first light source module 100g at the center of the circle and the second to seventh light source modules A first light source module assembly 251 composed of a total of seven LED light source modules 100 (100a, 100b, 100c, 100d, 100e, 100f) may be configured.

In addition, with respect to the light source module assembly configured in this way, a total of six first to sixth light source module assemblies 251 , 252 , 253 are composed of six combinations in a radial structure with the first light source module assembly 251 as the center of the circle again. , 254, 255, 256).

In this way, the first to sixth light source module assemblies 251 , 252 , 253 , 254 , 255 , and 256 may be configured to form a hybrid light source module 250 consisting of a total of six combinations.

At this time, in the first light source module assembly 251 forming the center of the circle, the first light source module 100g is the center of the circle and the first light source module 100g is the center of the first light source module 100g to form the outer peripheral surface in a radial structure. The second to seventh light source modules 100a to 100f are formed.

In particular, the reflective pattern of the first light source module 100g implements a circular pattern with a symmetrical pattern, and the second to seventh light source modules 100a to 100f implement an elliptical pattern with an asymmetrical reflective pattern. On the other hand, all of the first to seventh light source modules forming the second light source module assembly 252 to the sixth light source module assembly 256 implement a circular shape in a symmetrical pattern with a reflective pattern.

Implementation of such a reflective pattern is related to a hybrid structure, and will be described later in more detail with reference to FIGS. 9 and 10 .

In this case, the number of light source modules constituting the light source module assembly is 7, and the number of light source module assemblies constituting the hybrid light source module is 6, but the number is not limited thereto. configurable.

As such, as shown in FIG. 3 , in the hybrid type medical lighting device 300 according to the present invention, when a mode selection is made through the user's key input unit 312, the control module 320 performs surgery according to the selected mode. The hybrid type light source module 250 is controlled to suit the use mode 321 , the inspection mode 322 , and the dental mode 323 . Accordingly, a surgical light or medical lighting lamp that can be used in a surgical environment suitable for dental care (dental mode), general care (examination mode), and surgery (surgical mode) can be used with three modules in one product. make it possible to implement

4 shows the on/off control state of the light source module in (a) surgical mode, (b) examination mode, and (c) dental mode, respectively, in the configuration of the hybrid-type medical lighting device 300 of FIG. 2 . It is a drawing. 5 is a view showing a pattern image of a light source module in (a) surgical mode, (b) inspection mode, and (c) dental mode, respectively, in the configuration of the hybrid type medical lighting device 300 of FIG. 2 . . 6 is a view showing a lighting image of the light source module in (a) surgical mode, (b) examination mode, (c) dental mode, respectively, in the configuration of the hybrid type medical lighting device 300 of FIG. 2 . .

4 to 6, in the hybrid-type medical lighting device 300 of the present invention, the control module 320 controls the hybrid-type light source module 250, the surgical mode 321, the examination mode 322 ), to provide a dental mode 323 will be described in more detail.

In this case, the control module 320 may be connected to the first to sixth light source module assemblies 251 , 252 , 253 , 254 , 255 , 256 constituting the hybrid light source module 250 to control on/off. In addition, each individual light source constituting the first to sixth light source module assemblies 251 to 256, that is, the first to seventh light source modules 100a to 100g may also be connected to each other to control on/off.

First, the method for the control module 320 to implement the surgical mode 321 is as follows.

For example, in the hybrid-type light source module 250 , the remaining second to sixth light source module assemblies formed on the outer peripheral surface of the first light source module assembly 251 as well as the radial first light source module assembly 251 positioned at the center of the circle ( 252 to 256) are also turned on. Accordingly, a total of 42 light source modules constituting the first to sixth light source module assemblies 251 to 256 are turned on to realize the maximum pattern.

In addition, as shown in FIG. 5A , the pattern size can be varied from, for example, a minimum of 15 cm to 25 cm. As such, it is possible to change the size of the pattern size by on/off control of the hybrid type light source module 250 .

That is, as shown in FIG. 4A , when all LED light source modules are turned on, a maximum pattern size of 25 cm can be realized.

On the other hand, as shown in FIG. 6A , all seven light source modules 100a to 100g constituting the first light source module assembly 251 are turned on, and the second to sixth light source module assemblies 252 to 256 are turned on. By turning on only a portion, the size of the pattern size can be varied. For example, all of the first light source module assemblies 251 are turned on, and in the second to sixth light source module assemblies 252 to 256, only four light source modules are turned on among a total of seven light source modules, and the remaining three light source modules are turned off. It is a form that makes

That is, as shown in FIG. 6A , the second to sixth light source module assemblies 252 to 256 forming the outer circumferential surface around the first light source module assembly 251 forming the center of the circle (closer approach) Thus, the four light source modules forming the circumferential surface are turned on, and the three light source modules that are in contact with the circumferential surface (forming the circumferential surface in the farther direction) are turned off. This can also be confirmed in the form in which only the red light source module is turned on and the black light source module is turned off in the second to sixth light source module assemblies 252 to 256 in FIG. 4A .

This will be described later in FIG. 12 , but when two light sources are adjacent to each other ( 100a 100b ), the reflection unit 120 partially overlaps each other to indicate a lighting pattern formed in a pair of light source modules in which a boundary portion is formed, and a boundary portion is formed. A pair of light source modules has more overlapping areas, so it can be expected to improve the light efficiency by more than 30% compared to a single reflective structure. Through this, by individually controlling the first to sixth light source module assemblies 251 to 256 as well as each light source module 100a to 100g constituting them, the number or size of the light source modules that are controlled on/off in the surgical light mode Depending on the size of the variable size or the light output intensity can be adjusted.

As shown in FIG. 5A , a pattern size of at least 15 cm may be realized by turning on a total of 26 light source modules, 4 each of the first light source module assembly (7) and the second to sixth light source module assemblies (see FIG. 6A ). ). Then, a total of 42 light source modules, 7 each of the first to sixth light source module assemblies, may be turned on to realize a maximum pattern size of 25 cm (see FIG. 4A ).

In addition, the size of the variable size can be adjusted in the range of at least 15 cm to the maximum of 25 cm according to the adjustment of the number of lighting of the total of 26 to 42 light source modules, and the light output intensity can also be varied.

Next, a method for the control module 320 to implement the inspection mode 322 is as follows.

For example, in the hybrid light source module 250 , not only the first light source module assembly 251 positioned at the center of the circle but also the remaining second to sixth light source module assemblies 252 to 256 are partially turned on.

That is, as shown in FIGS. 4B and 6B , for the first to seventh light source modules 100a to 100g constituting the first light source module assembly 251 forming the center of the circle, the first light source at the center of the circle Only the module (100g) is turned on. On the other hand, the remaining six light source modules forming the outer circumferential surface in a radial structure from the center of the circle, that is, the second to seventh light source modules 100a to 100f are all turned off. At this time, as described above, the second to seventh light source modules 100a to 100f form an elliptical pattern with an asymmetric reflective pattern, and the first light source module 100g is designed to implement a symmetrical pattern.

In addition, the second to sixth light source module assemblies 252 to 256 that form an outer peripheral surface around the first light source module assembly 251 that form the center of the circle are adjacent (closely approached to form a peripheral surface) 4 Four light source modules are turned on, and three light source modules that are in contact (forming a circumferential surface in a farther direction) are turned off. This can also be confirmed in the form in which only the red light source module is turned on and the black light source module is turned off in the second to sixth light source module assemblies 252 to 256 in FIG. 4B .

At this time, the reflection pattern of the first light source module 100g implements a circular shape in a symmetrical pattern (the remaining second to seventh light source modules 100a to 100f are turned off), and the second light source module assembly 252 to the second light source module 100g is turned off. 6 All of the red light source modules turned on from the light source module assembly 256 implement a circular shape in a symmetrical pattern.

Accordingly, as shown in FIG. 5B , a symmetrical circular pattern may be implemented, and a pattern size of approximately 15 cm may be realized by turning on a total of 21 light source modules (see FIG. 4B ).

Next, a method for the control module 320 to implement the dental mode 323 is as follows.

For example, as shown in FIGS. 4C and 6C , in the hybrid type light source module 250 , only the first light source module assembly 251 positioned at the center of the circle is turned on, and the remaining second to sixth light source module assemblies 252 are turned on. to 256) are turned off. In addition, the first light source module 100g forming the center of the circle is also turned off for the first to seventh light source modules 100a to 100g constituting the first light source module assembly 251, and the remaining second to seventh light source modules 100a to 100g are turned off. Only the six light source modules forming the outer peripheral surface in a radial structure up to the light source modules 100a to 100f are turned on. At this time, as described above, since the second to seventh light source modules 100a to 100f implement an asymmetrical reflection pattern, it is possible to implement an elliptical pattern as shown in FIG. 5C .

On the other hand, the hybrid-type medical lighting device 300 of the present invention includes a distance detection sensor 311 for detecting a distance to a light irradiation target (treatment area), and an LED light source module 100 according to the distance sensed through the sensor. ) to configure the control module 320 to maintain the same amount of light by varying the light output intensity. Although this will be described in detail in FIG. 11 to be described later, the control module 320 may maintain the same amount of light by varying the LED output current for each distance in the LED light source module 100 in order to maintain the same amount of light.

It can be adjusted by varying the light output intensity of the light source module 100 by varying the distance between the light irradiation object and the light source module in the aforementioned surgical mode 321 , examination mode 322 , and dental mode 323 . .

Hereinafter, in the hybrid-type light source module 250 constituting the hybrid-type medical lighting device 300 according to the present invention, a total of six first to sixth light source module assemblies 251, 252, 253, 254, 255, 256) Looking in detail with respect to each light source module constituting the , this will be described in detail with reference to FIGS. 7 to 12 .

7A and 7B are a transparent perspective view and a transparent plan view showing the light source module 100 constituting the hybrid medical lighting device 300 according to a preferred embodiment of the present invention, and FIG. 8 is the light source module of FIGS. 7A and 7B. It is a diagram showing the structure of the reflector among the configuration of (100).

7 and 8, the light source module 100 constituting the hybrid-type medical lighting device 300 according to the present invention is a bowl-shaped upper portion of the LED module 110 in which three LEDs are combined. The reflector is configured by fastening the reflector 160 formed as one module in the form of a dual structure. ) can be composed of

Looking in more detail, the LED module 110 is composed of a combination of red, green, and blue LEDs, and each LED is formed to have a triangular shape forming a vertex to secure uniformity of light emitted from the LED or to use the condensing effect. Light efficiency can be improved. Here, a combination of three LEDs is taken as an example, but is not limited thereto, and three LEDs of red, green, and blue are necessarily configured, and any one of the three color LEDs is further added to form a combination of three or more multiple LEDs. It may be configured, and the plurality of LEDs may be configured in a shape having a symmetrical structure in the center, such as a square, to ensure uniformity of light.

The reflector 160 includes a main reflector 120 for reflecting the light generated from the LED module 110, and a vertical blocking structure 150 for blocking the vertical light generated from the LED module. do. At this time, in the present invention, the reflector 160 has a dual reflection structure by forming sub-reflectors 130 not only in the main reflection unit 120 but also in the vertical blocking structure 150 formed at the center. That is, it may be formed to include a first reflective part 130 formed in the center and a second reflective part 120 formed in a peripheral part surrounding the central part. In addition, since the vertical blocking part 140 is formed to be spaced a predetermined distance from the upper part of the LED module 110 and is formed at the center of the bottom of the first reflecting part 130 and the second reflecting part 120 , the The LED module 110 may be located at the center of the bottom of the first reflector 130 and the second reflector 120 .

The first and second reflectors 130 and 120 may have concentric circles centered on the LED module 110, have a predetermined radius of curvature, and may be formed in a bowl shape with an empty bottom.

In addition, the first and second reflectors 130 and 120 are formed of a reflector coated with a concave bowl-shaped reflective material with an open lower part, and a side cross-section of the first reflector 130 and the second reflector are formed. The side cross-sections of the part 120 may be disposed parallel to each other at a predetermined distance.

Here, it is preferable that curved grooves (not shown) having a plurality of radii of curvature are formed side by side in the horizontal and/or vertical direction on the inner surfaces of the reflector, that is, the first and second reflecting units 130 and 120 . This is because when the side light generated by the LED module 110 is reflected by the reflector, when each reflective surface is smooth and uniform, the probability of forming a shadow that appears as the vertical light is blocked by the vertical blocking unit 140 increases. Therefore, it is desirable to form a plurality of reflective surfaces so that the inclination angle of the reflective surfaces can be slightly different.

As described above, in the reflector 160 , the bowl-shaped first and second reflectors 130 and 120 having an open lower part are formed in a dual manner in a concentric circle centered on the LED module 110 , and the lower part of the reflector 160 . The vertical blocking unit 140 blocking the vertical light generated from the LED module 110 located in the second reflecting unit 120 is connected to the lower part by two legs to form a 'L' shape as a whole.

Accordingly, the vertical blocking unit 140 may be fixedly supported by being connected to two legs (170a or 170b in FIG. 10 ) extending from the lower end of the second reflecting unit 120 .

In addition, the vertical blocking part 140 is connected at the lower part of the first reflecting part 130 , and the lower ends of the vertical blocking part 140 and the first reflecting part 130 are grooves/protrusions, bolts-nuts. The first reflecting unit 130 may be fixedly supported by the vertical blocking unit 140 by being fastened in various forms such as a coupling type.

In this way, a bright point generated in the vertical light of the LED module 110 light source is removed through the vertical blocking unit 140 .

Next, the dual reflector connected to the vertical blocking unit 140 primarily reflects the side light from the central first reflector 130 , and secondarily surrounds and surrounds the first reflector 130 . With a double structure that reflects the side light through the part 311, the light collection and straightness in the irradiation direction of the LED module 110 light source are improved, the uniformity of the illumination light pattern is high, and the color separation phenomenon is small. to provide. That is, through the reflector 160 , the light in the vertical direction among the light generated by the LED module 110 is blocked by the vertical blocking unit 140 , and the side light irradiated to the side at a predetermined angle is first reflected, respectively. The part 130 and the second reflector 120 are reflected from the reflector, which is the inner surface of the dual reflector, so that the light irradiated from the LED module is irradiated forward without leakage. Through this, it is possible to remove ambient light outside the treatment area (pattern), prevent glare from the operator, and reduce treatment time and increase efficiency by improving light output by more than 30% compared to a single reflective structure.

9 is a schematic diagram showing various examples of the pattern shape of the inner surface of the reflection unit in the light source module 100 of FIGS. 7A and 7B .

As shown in FIG. 9 , the reflector, which is the inner surface of the second reflector 120 that reflects the light generated from the LED module 110 in the light source module 100 according to the present invention, is a curved groove having a plurality of radii of curvature. These are formed side by side in the vertical direction (FIG. 9 (a)), are formed side by side in the horizontal direction (FIG. 9 (b)), are formed crosswise in the horizontal and vertical directions (FIG. 9 (c)), or concentrically is formed and may be formed to cross one time in the horizontal and vertical directions (FIG. 9(d)).

In addition, not only the inner surface of the second reflecting unit 120 but also the inner surface of the first reflecting unit 130 may be formed in various patterns according to FIGS. 9 (a) to 9 (d). have.

At this time, FIGS. 9(a) to 9(c) are structures capable of realizing an asymmetric pattern, and FIG. 9(d) is a pattern structure of a reflective plate suitable for implementing a symmetrical pattern.

When the curved grooves of various patterns are formed in this way, the reflective surfaces form reflective surfaces having different tilting angles, and the dispersion effect of the LED 200 reflected light is further increased to increase the uniformity of the pattern and reduce the color separation. be able to

That is, when a smoothly concave inner surface is formed, it is constantly reflected according to the angle of the side light irradiated from the LED module 110 and irradiated to the illumination area. The formed circular shadow is formed, and the possibility that the donut-shaped illumination light is formed increases, so that the uniformity of the pattern is deteriorated and the color separation phenomenon occurs.

Accordingly, in the present invention, in order to form a plurality of reflective surfaces having different reflection angles on the reflector, which is the inner surface of the second reflective unit 120 and/or the first reflective unit 120 , a curved groove having a plurality of curvature counterattacks is horizontally arranged side by side. And/or by forming in the vertical direction, it is possible to increase the dispersion effect of the reflected light, to remove the shadow in the center, and to bring about the effect of reducing the color separation phenomenon with high uniformity of the illumination light pattern.

It is a diagram showing the slope structure.

As shown in FIG. 10 , it may be configured in the form of a reflective surface (Multi Facet) to implement symmetric and asymmetric patterns.

First, as shown in FIG. 10A , a plurality of curved grooves having a plurality of radii of curvature in the reflective surface for reflecting light from the first and/or second reflecting unit are formed side by side in the horizontal and/or vertical directions, The reflective surface is composed of a plurality of surfaces, and a symmetrical pattern can be formed by forming the same vertical and horizontal cross-sections of each surface.

As shown in FIG. 10B , a plurality of curved grooves having a plurality of radii of curvature are formed side by side on the reflective surface for reflecting light from the first and/or second reflective part in the horizontal and/or vertical direction, and the reflective surface An asymmetric pattern can be formed by forming a plurality of surfaces and forming different vertical and horizontal cross-sections of each surface.

11 is a diagram illustrating a pattern size and a light output control method for each distance in the light source module 100 of FIGS. 7A and 7B .

As shown in FIG. 11 , as the distance from the LED light source to the treatment area, the pattern size changes depending on the focal length, so it is necessary to maintain the light uniformity.

Accordingly, the hybrid medical lighting device 300 of the present invention may further include a light output control module that maintains the same amount of light by varying the LED output current for each distance in the LED module 110 to maintain the same amount of light. have. The light output control module may be disposed in the form of a microprocessor chip on the LED module 110 or may be implemented integrally with the control module 320 .

In this light output control module, a sensor 311 for detecting the distance from the LED module 11) to the light irradiation object (treatment area), and the light output intensity of the LED module according to the distance sensed through the sensor It may be composed of a light control unit that maintains the same amount of light by varying the light intensity (see FIG. 3 ).

Table 1 is a table showing the pattern size and light output intensity variable design method for each distance detected by the sensor.

pattern size 10cm 20cm 30cm survey distance 30cm 50cm 70cm LED output current (If) 150mA 300mA 500mA

Referring to Table 1, it is possible to maintain the same amount of light by setting a predetermined threshold current according to the sensing distance through the distance sensor so that the current is variable for each distance.

For example, when the focal length (irradiation distance) is 30 cm, if the pattern size is 10 cm, the intensity of the LED output current is set to 150 mA, and when the focal length (irradiation distance) is 50 cm, if the pattern size is 20 cm, the intensity of the LED output current is set to 300 mA, and when the focal length (irradiation distance) is 70 cm and the pattern size is 30 cm, the intensity of the LED output current may be set to 500 mA.

That is, in the existing case, only proximity irradiation was possible, so there was a problem in that the light output was lowered when the distance increased. do. For example, since it is possible to treat skin of various areas and overlap irradiation through a plurality of modules, a decrease in light output can be prevented.

As described above, in the hybrid medical lighting device 300 according to the preferred embodiment of the present invention, seven light source modules 100 shown in FIGS. 7A and 7B are combined to form one light source module assembly 251, 252, 253, 254, 255, 256).

12 is a view showing a module structure in the light source module assembly 100a of the hybrid type medical lighting device 300 according to a preferred embodiment of the present invention. Two pairs of light source modules 100a and 100b interconnected from the seven light source modules 100a to 100g constituting the That is, FIG. 12 shows a modularized coupling configuration in which the LED module and the reflector are configured as a pair, and two pairs of light source modules 100a and 100b connected in series are connected. In addition, the light source modules continuously connected in this way can be fastened to the upper portion of the substrate of each light source module body assembly to be coupled as a single body.

As shown in FIG. 12 , each light source module 100 has a reflector 160 in which a bowl-shaped reflector is formed as one module in a dual structure form on the upper portion of the LED module 110 in which three LEDs are combined. ), and can be largely composed of a single reflector 160 and an LED module 110 of three combinations of a red LED, a blue LED, and a green LED.

At this time, the vertical blocking portions 140a and 140b formed to be spaced apart from each other on the LED module 110a or 110b are disk-shaped, but are not limited thereto, and may be formed in various ways, such as a hemispherical shape.

Also, a boundary portion 220 in which at least a pair of edges overlap each other is formed between each pair of adjacent second reflection units, and the boundary portion 220 may have a concave shape. That is, the second reflection unit 120 preferably has a structure in which a pair of reflection units 120a or 120b having a boundary portion 220 formed adjacent to each other are arranged side by side in the horizontal direction, and the boundary portion 220 is formed in a concave shape. By lowering the boundary ridge between the two reflective parts 120a or 120b, each LED module (110a, 110b) light overlaps each illumination area, thereby increasing pattern uniformity and reducing color separation.

In this way, when two light sources are adjacent to each other, the reflection unit 120 partially overlaps each other to indicate a lighting pattern formed by a pair of light source modules in which a boundary is formed, and the pair of light source modules in which a boundary is formed has a larger overlapping area. It can be expected to improve the light efficiency by more than 30% compared to the single reflective structure.

Accordingly, as described above, light output intensity and light efficiency can be improved according to the number or size of light source modules that are controlled on/off in the hybrid light source module.
