  It can be understood that the present invention has a structure in which the dimming unit 100 is disposed in the housing 300 provided with the light emitting module 400 as illustrated.

  The dimming unit 100 is provided in a housing 300 having a socket base 301 at a lower portion thereof, and varies the luminous flux of the semiconductor optical element 401.

  The light emitting module 400 is disposed on the upper portion of the housing 300 and includes at least one semiconductor optical element 401 of an AC direct drive system.

  Here, as described above, the semiconductor optical device 401 of the present invention operates in an alternating current direct drive system, so that the dimming unit 100 can be utilized on the premise that the power consumption can be adjusted by resistance. It can be said that this is the main technical means of the present invention.

  Therefore, when the user needs to change the luminous flux of the semiconductor optical element 401 in a normal light bulb type lighting device in which the socket base 301 of the housing 300 is coupled to a socket (hereinafter not shown), the dimming unit 100 is used. By operating, dimming control can be implemented.

  The present invention can be applied to the above-described embodiment, and it is needless to say that the following various embodiments can also be applied.

  First, the light emitting module 400 includes the semiconductor optical element 401 as described above, and includes the substrate 410 and the AC direct-coupled drive IC 420.

  The substrate 410 is disposed on the upper portion of the housing 300, and the semiconductor optical device 401 is disposed. The AC direct-coupled drive IC 420 is disposed on the substrate 410, and a power supply device including an existing SMPS or PSU is installed. A circuit for driving the semiconductor optical device 401, which is omitted and is directly connected to an alternating current, is integrated.

  Accordingly, since AC and DC conversion devices such as existing lighting devices and power supply devices that occupy a large volume and load can be omitted, the housing 300 in which the dimming unit 100 is mounted in the space occupied by the above unnecessary components. The installation space 310 can be substituted.

  The dimming unit 100 is disposed below the substrate 410 so that smooth operation is not hindered.

  However, the dimming unit 100 does not necessarily have to be disposed below the substrate 410, and the dimming unit 100 may be disposed above the substrate 410 depending on circumstances.

  On the other hand, the dimming unit 100 is for changing the luminous flux of the semiconductor optical element 401 as described above, and it can be understood that the dimming unit 100 has a structure including the variable resistance part 110 and the key part 120.

  More specifically, the variable resistance unit 110 is electrically connected to the light emitting module 400 and the socket base 301. The power consumption necessary for the operation of the semiconductor optical device 401 is adjusted by adjusting the resistance value by a dial method. Can be varied.

  The key unit 120 is coupled to the end of the rotating shaft 111 of the variable resistance unit 110 that rotates forward and backward, and is for mechanically connecting to the light control unit 100.

  More specifically, the key portion 120 uses a structure including a fastening pattern 122 in which a plurality of top portions and groove portions are repeated along the outer peripheral surface of the cylindrical key body 121, or a cylindrical key body. Of course, it is possible to selectively use a structure including a fastening jaw 123 that is cut out from the top surface of 121 in the vertical direction.

  That is, the key portion 120 is connected to a light control unit 200 described later, and is configured to accurately transmit a rotational force that rotates the light control unit 200 forward and backward to the rotation shaft 111 of the light control unit 100. Then, various applications and modified designs are possible without being limited to the above-described two-structure embodiments.

  Meanwhile, the present invention may further include a dimming control unit 200 disposed between the optical member 500 disposed on the upper side of the housing 300 and the housing 300 and connected to the dimming unit 100 and capable of rotating forward and reverse. .

  Specifically, the dimming control unit 200 is for performing the light beam control of the dimming unit 100 by forward / reverse rotation, that is, for performing the control operation for changing the light beam of the semiconductor optical element 401 mechanically. It can be understood that the structure includes the rotation bar 220.

  The adjustment member 210 is a ring-shaped member that is disposed between the lower end edge of the optical member 500 and the upper edge of the housing 300 and rotates forward and backward.

  The rotation bar 220 extends from one side of the adjustment member 210 toward the center of the adjustment member 210 and is connected to the light control unit 100.

  Here, on the outer surface of the adjustment member 210, the scale display or the light flux is grasped step by step so that the change in the light flux of the semiconductor optical element 401 due to the rotation direction can be grasped with the naked eye on the basis of the point where the rotation bar 220 begins to extend. Of course, it is possible to further form a recognizing means 211 such as a numeral.

  At this time, the dimming control unit 200 can be formed such that the guide groove 201 is depressed along the outer peripheral surface of the lower end portion of the optical member 500 so that the adjustment member 210 can be fixed.

  The dimming control unit 200 may further include a rotation slit 202 having a predetermined length that passes through the outer peripheral surface of the lower end portion of the optical member 500 and that the rotation bar 220 reciprocates.

  The dimming control unit 200 may further include a rotation notch 203 having a predetermined length along which the rotation bar 220 is reciprocated along the lower edge of the optical member 500.

  The optical member 500 is extended from the lower end of the optical member 500 to form the guide groove 201, the rotation slit 202 and the rotation notch 203, and the edge is fixed to the upper portion of the first housing 300. It is preferable to further include a fastening ring portion 510.

  In addition, a rotating bar 220 of the dimming control unit 200 formed on the upper surface 304 of the housing 300 and coupled to the outer peripheral surface of the fastening ring portion 510 is provided in the housing 300 for smooth operation of the dimming control unit 200. It is preferable to further form a rotation stepped portion 520 that provides a predetermined range of space for rotation.

  The mounting space of the light control unit 100 is secured by fixing the edge of the substrate 410 on the upper surface of the rotational step portion 520, and the space necessary for the rotational operation of the light control unit 200, that is, the rotational bar 220, can be secured. It becomes like this.

  At this time, the turning step 520 forms a notch as shown in the enlarged plan view from the viewpoint B in FIG. 2, but the length l of the notch opened by the turning step 520 is the above-described length l. If the lengths of the rotation slit 202 and the rotation notch 203 are accommodated, the rotation range of the rotation bar 220 can be limited naturally.

  The dimming control unit 200 is formed with a fastening groove (hereinafter not shown) corresponding to the shape of the key part 120 formed at the end of the rotating bar 220 and provided at the upper end of the dimming unit 100. It is preferable to further include a fastening head 222.

  Here, if the shape of the fastening groove is a structure in which the rotating bar 220 does not rotate with respect to the key part 120 of the light control unit 100, the fastening groove is depressed to correspond to the shapes of the various key parts 120 as described above. Of course, it should be formed.

  In the present invention, a structure in which the dimming control unit 200 is detachably coupled to the fastening ring portion 510 of the optical member 500 is illustrated, but the present invention is not necessarily limited to such a structure. It can also be formed integrally.

  That is, the user can directly grip and optically rotate the optical member 500 connected to the light control unit 100 to change the light flux.

  Such a variable operation of the luminous flux can be useful in a case where it must be carried out in a state where the lighting device is turned off.

  In the case of a normal incandescent bulb, the glass sphere (bulb) corresponding to the optical member has a high heat generation level, and if it is touched with bare hands, it is burned. However, in the case of a lighting device employing a semiconductor optical element, Since the member 500 is generally made of a material having excellent heat resistance and durability, the degree of heat generation is significantly lower than that of a normal incandescent bulb.

  However, although the degree of heat generation is lower than that of a normal incandescent light bulb, it is preferable to operate the dimming control unit 200 in a state where the power is turned off for safety.

  On the other hand, as shown in FIG. 3, the present invention can be configured such that the dimming unit 100 and the dimming control unit 200 can be coupled to each other.

  That is, the dimming control unit 200 includes a rotating bar 220 that extends from one side of the adjusting member 210 toward the socket base 301 and is connected to the dimming unit 100. The rotating bar 220 includes the first bar. The embodiment of the structure including 220a and the second bar 220b is applied.

  The first bar 220 a extends from one side of the adjustment member 210 toward the center of the adjustment member 210.

  The second bar 220b extends from the end of the first bar 220a toward the socket base 301 and is connected to the dimming unit 100.

  Further, the dimming control unit 200 has one end portion rotatably connected to the end portion of the rotating bar 220 and the other end portion being a rotation link integrally fixedly coupled to the rotation shaft 111 of the dimming unit 100. 230 may further be included.

  The first bar 220a of the dimming control unit 200 is penetrated through the rotation slit 202 or the rotation notch 203 formed in the fastening ring portion 510 of the optical member 500 and is rotated through the rotation slit 202 or the rotation. Light flux control of the light control unit 100, that is, dimming control can be implemented while reciprocating the length of the dynamic notch 203.

  In addition to the above-described embodiment, the dimming control unit 200 is mounted on a housing base 302 disposed between the heat sink 303 and the socket base 301 that constitute the upper side of the housing 300 as shown in FIG. Of course, an embodiment in which the housing base 302 itself is connected to the dimming unit 100 and can rotate forward and backward can also be applied.

  As described above, the present invention provides an optical semiconductor lighting device that can provide a dimming effect at low cost in any environment by providing a light control function to the light bulb type lighting device itself that uses an optical semiconductor as a light source. It can be understood that the basic technical idea is to provide.

  Of course, those having ordinary knowledge in the field within the scope of the basic technical idea of the present invention can make many other modifications and applications.
