FIG. 6 is a sectional view of the light source module 100 constituting the light irradiator head module 200 of FIG. And the LED module 110 is composed of three combinations of the red LED, the blue LED, and the green LED.

4 to 6, a medical light irradiator head module 200 according to a preferred embodiment of the present invention is a housing form of a light source module 100, in which a light source module 100 is mounted on each vertex of a rhombic shape, It is an open structure.

For example, the light irradiator head module may correspond to an illuminating lamp constituting a part of a unit chair of a dental unit, may be applied to the ceiling through the connecting part 240 and fixed or may be combined with a balance arm system (not shown) It can also be applied to a medical chair or a portable medical device.

The balance arm system also serves as a support structure for the light irradiator head module 200 connected to the clinic chair and the like. The light irradiator head module 200 (for example, a light illuminator) And can be moved conveniently to a desired position and stably fixed.

Here, the light source module 100 constituting the medical light irradiator head module 200 includes a reflector formed as a single module in the form of a dual reflector on the top of the LED module 110 as a light source 160). 6, the LED module 110 is formed of a combination of three LEDs of red, green, and blue, and each LED is formed to have a triangular shape that forms apexes, The light efficiency can be improved by securing the property or concentrating the light. Alternatively, the LED module may be formed of any one of red, green, and blue LEDs, and may be formed of a combination of three light source modules of red, green, and blue LEDs.

6, the light irradiator head module 200 is formed of a combination of red, green, and blue LEDs, and each LED is formed to have a triangular shape that forms apexes. In the LED module 110, Red, green, and blue LEDs are formed. Thus, four light source modules 100 are formed at each vertex of a rhombus, so that the volume and size of the light source module 100 can be reduced. In another embodiment, the three light source module combinations of red, green, and blue LEDs form three rows, and a pair of three rows are formed of two or more of the light source modules 100, X n. ≪ / RTI >

The light source module 100 includes a LED module 110 (not shown in FIG. 5) and a reflector 160 that reflects the light emitted from the LED module and concentrates the light toward the front. The reflector 160 includes a main reflector 120 for reflecting the light generated by the LED module 110 and a vertical shielding structure 120 for blocking vertical light generated from the LED module 110. [ (150).

At this time, in the present invention, the reflector 160 forms a sub reflector 130 not only in the main reflector 120 but also in the vertical cut-off structure 150 formed at the center, and has a dual reflector structure. That is, the first reflecting portion 130 formed at the center portion and the second reflecting portion 120 formed at the peripheral portion surrounding the center portion may be formed in a double layer. The vertical blocking part 140 is formed at a predetermined distance from the upper part of the LED module 110 and is formed at the bottom center of the first reflecting part 130 and the second reflecting part 120, The LED module 110 may be positioned at the bottom center of the first and second reflectors 130 and 120.

The first and second reflectors 130 and 120 may be concentrically formed around the LED module 110 and may have a predetermined radius of curvature and an empty bottom.

The first and second reflectors 130 and 120 are formed of a reflector coated with a reflective material in the form of a concave bowl having an open bottom, And the side surfaces of the portion 120 may be disposed parallel to each other with a predetermined distance therebetween.

The inner surfaces of the reflectors, that is, the first and second reflectors 130 and 120, are preferably formed in a horizontal and / or vertical direction along curved grooves (not shown) having a plurality of curvature radii. This is because when the side light generated by the LED module 110 is reflected by the reflector, the reflection surfaces smoothly become uniform, and the probability that a shadow appears due to the vertical light blocking due to the vertical blocking portion 140 is increased This is because it is preferable to form a plurality of reflection surfaces so that the tilt angle of the reflection surface may be slightly different.

As described above, the bowl-shaped first and second reflectors 130 and 120, which are open at the bottom of the reflector 160, are formed in a concentric manner around the LED module 110 in a dual manner, The vertical blocking portion 140 blocking the vertical light generated by the LED module 110 located at the second reflective portion 120 is connected to the lower portion of the second reflective portion 120 by two legs to form a '

The vertical cut-off part 140 is connected to two legs 170a and 170b extending from the lower end of the second reflecting part 120, and can be fixedly supported.

The vertical cut-off part 140 is connected to the lower part of the first reflecting part 130. The lower ends of the vertical cut-off part 140 and the first reflecting part 130 are connected to a groove / And the first reflecting part 130 may be fixedly supported by the vertical blocking part 140. The first reflecting part 130 may be fixed and supported by the vertical blocking part 140. [

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

The dual reflecting part connected to the vertical blocking part 140 may reflect the side light to the first reflecting part 130 at the central part and the second reflecting part 130 surrounding the first reflecting part 130, A light source module having a double structure that reflects side light through the light source unit 311 and improves convergence and straightness in the irradiation direction of the LED module 110 light source, to provide. That is, the light in the vertical direction of the light generated by the LED module 110 is blocked by the vertical cut-off portion 140 through the reflector 160, and the side light irradiated to the side surface at a certain angle is reflected by the first reflection And is reflected by the reflector that is the inner surface of the dual reflector of the first reflector 130 and the second reflector 120 so that the light is forwardly emitted without leakage of the light emitted from the LED module. By this, it is possible to eliminate the ambient light other than the treatment area (pattern), to prevent the operator's glare, and to increase the light output by 30% or more than that of the single reflection structure.

7 is a schematic view showing various examples of a pattern shape of the inner surface of the main reflector, i.e., the second reflector 120, in the light source module 100 of FIGS.

7, the reflector, which is the inner surface of the second reflector 120 that reflects the light generated from the LED module 110, is formed such that curved grooves having a plurality of curvature radii are formed in parallel in the vertical direction (Fig. 7A), horizontally (Fig. 7B), horizontally and vertically (Fig. 7C), or concentrically and once horizontally and vertically (Fig. 7 (d)).

In addition, not only the inner surface of the second reflector 120 but also the inner surface of the first reflector 130 may be formed in various shapes of patterns according to Figs. 7 (a) to 7 (d) .

7 (a) to 7 (c) show a structure capable of implementing an asymmetric pattern, and FIG. 7 (d) shows a pattern structure of a reflector suitable for implementing a symmetric pattern.

When the curved grooves are formed in various patterns as described above, the reflective surfaces form reflection surfaces having different tilting angles, thereby further increasing the dispersion effect of the reflected light of the LED module 110, thereby increasing the uniformity of the pattern, . That is, when the inner side is formed smoothly, the illumination light is irradiated to the illumination area uniformly according to the angle of the side light irradiated by the LED module 110, so that the illumination light pattern of the illumination area is focused at the center by the vertical interception part 140 The shape of the formed circular shadow is formed, and the possibility that the donut-shaped illumination light is formed becomes higher, the uniformity of the pattern is lowered and the color separation phenomenon occurs.

Accordingly, in order to form a plurality of reflection surfaces having different reflection angles with respect to the reflector, which is the inner surface of the second reflector 120 and / or the first reflector 130, curved grooves having a plurality of curvature counter- And / or in the vertical direction, the effect of dispersing the reflected light is enhanced, shadows are removed at the center, the uniformity of the illumination light pattern is high, and the effect of reducing the color separation phenomenon can be obtained.

In addition, a boundary portion 220 in which at least a pair of rim portions overlap each other is formed between each pair of adjacent second reflection portions, and the boundary portion 220 may have a concave shape. That is, the second reflection part 120 preferably has a structure in which a pair of reflection parts 120a or 120b with the boundary part 220 formed adjacent to each other are arranged side by side in the horizontal direction, and the boundary part 220 has a concave shape. The boundary between the two reflectors 120a and 120b is lowered so that the light of each LED module 110a and 110b is overlapped with each illumination area to increase the uniformity of the pattern and reduce the color separation phenomenon.

In the case where the two light sources are adjacent to each other, the reflector 120 partially overlaps each other to form an illumination pattern formed by a pair of light source modules having a boundary portion. And a light efficiency improvement of 30% or more can be expected over a single reflection structure.

The LED module 110a or 110b may be connected to the LED module 110a or 110b through two legs 170a or 170b of 'a' shape connected to the open bottom edge of the second reflector 120a or 120b, as shown in FIG. 8 (a) A vertical discontinuous portion 140a or 140b is formed on the upper portion of the LED module 110a or 110b to block the vertical light generated from the LED module 110a or 110b, The bright spot of the center is removed. In addition, the formation of the shadow due to the removal of the bright light spot can be achieved by allowing the side light to be fused to each other in the focal length range by the reflectors of the first and second reflectors 130a or 130b (120a or 120b) .

The LED module 110a or 110b may be connected to the LED module 110a or 110b through two legs 170a or 170b of 'a' shape connected to the open bottom edge of the second reflector 120a or 120b, as shown in FIG. 8 (b) The vertical blocking portion 140a or 140b having a downwardly convex hemispherical shape positioned at the upper portion is formed to reflect the vertical light generated from the LED module 110a or 110b to the side through the convex surface coated with the reflective material , And is irradiated forward by the reflector on the side surface again.

The embodiment shown in FIG. 8B differs from the embodiment shown in FIG. 8A in that the vertical blocking portion 140a or 140b originally blocks the vertical light generated in the LED module 110a or 110b The LED module 110a or 120b may be formed by reflecting a light beam reflected by the inner surface of the first and second reflecting portions 130a or 130b (120a or 120b) through a convex reflecting surface, The light reflected by the vertical light of the LED module 110a or 110b can be used as a light source as well as the reflected light L reflected and irradiated through the side light of the LED module 110b.
