[ The first connection terminal 161a and the first connection terminal 161a are symmetrical with respect to the center axis of the end cap 150. [

The outer cap 130 is rotatably coupled to the end cap 150. As the outer cap 130 is rotated, the power unit is rotated together with the outer cap 130. Accordingly, the connection terminal 161 and the power unit are selectively connected to each other according to the rotation angle of the outer cap 130. The outer cap 130 is preferably made of an insulating material to prevent short-circuiting.

The outer cap 130 may have a cylindrical structure having one side opened and the other side clogged and having a central axis parallel to the longitudinal direction. For example, the outer cap 130 includes at least a plate 131 having a size corresponding to the end plate 151, and a space extending from the edge of the plate 131 to accommodate the end cap 150 therein As shown in FIG.

One end of the terminal pin 141 is exposed to the outside of the outer cap 130 and the other end of the terminal pin 141 is positioned inside the outer cap 130.

The outer wall 133 extends from the rim of the plate 131 to form a space in which the end cap 150 is accommodated. The outer wall 133 has a cylindrical shape.

The outer cap 130 is extrapolated to the end cap 150. The outer cap 130 and the end cap 150 share a central axis so that the outer cap 130 is extrapolated to the end cap 150 to facilitate rotation. Specifically, the end cap 150 is constrained to rotate in the optical housing 120. The plate 131 of the outer cap 130 is disposed so as to surround the end plate 151 of the end cap 150.

The outer cap 130 further has a guide protrusion 135 formed thereon. The guide protrusion 135 is inserted into the guide groove 155 and slides along the guide groove 155. The guide protrusion 135 slides in the guide groove 155 and guides the rotation path of the outer cap 130 when the outer cap 130 rotates so that the outer cap 130 is detached from the end cap 150 prevent.

A plurality of guide protrusions 135 are formed along the circumferential direction of the outer cap 130. Specifically, the guide protrusion 135 is formed protruding from the inner surface of the outer wall 133. At least two guide protrusions 135 are arranged on an arc centered on the axial direction of the outer cap 130.

Further, the outer cap 130 is further provided with a terminal guide groove 136. The terminal guide groove 136 provides a space through which one end of the connection terminal 161 is inserted and guided. Further, the terminal guide groove 136 provides a space in which a connection terminal 170 of a power source unit to be described later is located. The terminal guide groove 136 guides the movement of the connection terminal 161 and strengthens the connection between the connection terminal 161 and the connection terminal 170.

The terminal guide groove 136 is formed by recessing the inner surface of the plate 131 outwardly. Specifically, the terminal guide groove 136 is in the shape of a ring having a radius corresponding to the turning radius of the connecting terminal 161.

The terminal guide groove 136 is formed in the path of the two connecting terminals 161 that move relatively when the outer cap 130 is rotated. Specifically, the terminal guide groove 136 is ring-shaped with a central axis parallel to the front-rear direction, and the terminal guide groove 136 and the central axis of the end cap 150 are shared.

The power source unit electrically connects the light source unit 110 and an external power source. The power unit may be fixed to the outer cap 130, one side exposed to the outside of the outer cap 130, and the other side positioned inside the outer cap 130.

For example, the power source unit may include a terminal pin 141 and a connection terminal 170. [

The terminal pin 141 and the connection terminal 170 may include a conductive material. For example, the terminal pin 141 and the connection terminal 170 may be formed using a material selected from among Cu, Al, Ti, and Mg, and may be formed using Cu. Further, another material may be further coated on the surface of Cu.

One end of the terminal pin 141 is exposed through the outer cap 130 and the other end is positioned inside the outer cap 130. The connection terminal 170 is brought into contact with the other end of the terminal pin 141.

The terminal pin 141 has a size and an arrangement that can be inserted into a standardized socket. Preferably, the terminal pins 141a and 141b may include at least two terminals. The two terminal pins 141 may be supplied with power of the same polarity, may be supplied with a power of another polarity, and either one of the two terminal pins 141 may be an insulator.

The connection terminal 170 is electrically connected to the terminal pin 141 and is selectively connected to the connection terminal 161 by rotation of the outer cap 130. The connection terminal 170 may be provided with a pair corresponding to the terminal pin 141. Specifically, the connection terminal 170 includes a first connection terminal 170a and a second connection terminal 170b.

The connection terminal 170 is accommodated in the outer cap 130. For example, the connection terminal 170 is disposed in at least a part of the movement path of the connection terminal 161. [ That is, the connection terminal 170 is disposed on a part of the path through which the connection terminal 161, which is relatively rotated during the rotation of the outer cap 130, is moved so that the connection terminal 170 can be selectively moved in accordance with the rotation angle of the outer tap. And the connection terminal 161 are connected.

Specifically, the connection terminal 170 is disposed in a partial area of the circle arc, which is the movement path of the connection terminal 161. [ The connection terminal 170 is in the shape of an arc having a radius equal to the radius of rotation of the connection terminal 161, and the center thereof overlaps with the center axis of the end cap 150.

As another example, the connection terminal 170 is fixed to the outer cap 130. Specifically, the connection terminal 170 has a connection hole 171 into which the terminal pin 141 is inserted. The connection hole 171 is inserted into the plate 131 to define a space into which the terminal pin 141 is inserted.

As another example, the connection terminals 170 are disposed along the terminal guide grooves 136. The connection terminal 170 is inserted into the terminal guide groove 136 and fixed to the terminal guide groove 136 by an elastic force.

Specifically, the first connection terminal 170a is inserted into one region of the terminal guide groove 136, and the second connection terminal 170b is inserted into another region of the terminal guide groove 136, Respectively. As shown in Fig. 6, the first connection terminal 170a and the second connection terminal 170b form a circular arc whose center angle is smaller than 180 degrees. The distance between the first connection terminal 170a and the second connection terminal 170b is such that the connection terminal 161 is located therebetween. When the connection terminal 161 is positioned between the first connection terminal 170a and the second connection terminal 170b, the power supply unit and the light source unit 110 are in the non-conduction state.

The connection terminal 170 is disposed on the surface parallel to the central axis of the end cap 150 in the terminal guide groove 136. Therefore, the connection terminal 170 is in surface contact with the connection terminal 161 inserted into the terminal guide groove 136.

The end cap (130) and the end cap (150) further include a rotation restricting portion that is formed by mutually engaging and restricting rotation.

Restrains the rotation of the outer cap 130 of the rotation restricting portion, permits rotation in one direction, and restrains rotation in the other direction. Specifically, the rotation restraining portion restrains rotation in one direction and allows rotation in the other direction by applying a predetermined external force.

For example, the rotation restraining portion includes an inner gear 154 having a plurality of teeth arranged in a circumferential direction on the end cap, and an outer gear 134 disposed on the outer cap 130 and engaged with the inner gear 154 do. The inner gear 154 and the outer gear 134 have axes which overlap the central axis of the end cap 150.

 The inner gear 130 and the outer gear 134 are engaged with each other to restrain the rotation of the outer cap 130. When a predetermined external force is applied, the inner gear and the outer gear 134 are elastically deformed, . Therefore, the inner gear 154 and the outer gear 134 are preferably made of a resin material having an elastic force.

Further, in order to allow only rotation in one direction, a plurality of teeth are formed to be inclined to one side in the radial direction of the end cap. That is, the plurality of teeth have two inclined surfaces, and the inclination of one of the inclined surfaces may be smaller than the inclination of the other inclined surface.
