The operation of the present invention configured as described above will be described.

The lamp (1) is to be installed horizontally on the power connector 100 installed on the wall of the position higher than the goods displayed in order to illuminate the goods displayed on the showcase or the goods displayed or The bulb 3 is rotatably mounted on the semi-circular support 22 of the bracket 2 even when it is installed vertically on the power connector 100 installed at the bottom of the shelf located at the top of the shelf to illuminate the product. By rotating the weight in the direction in which the center of gravity due to its own weight will be able to brightly illuminate the goods displayed under the lamp (1).

That is, as shown in FIG. 4, in order to horizontally install the lamp 10 at the power connector 100 installed on the wall, the socket 4 formed on the straight attachment part 21 of the bracket 2 is assembled. When the semi-circular support part 22 of the bracket 2 is installed to be in a horizontal state, the light bulb 3 rotatably mounted to the support part 22 is a light case 33 having a center of gravity. Since the lower side of the hinge shaft 6 is rotated toward the lower side, the illumination case 33 is always located at the lower side and the heat dissipation member 350 is positioned at the upper side.

In addition, the plurality of LEDs 342 radially arranged in the LED module 34 mounted inside the lighting case 33 of the light bulb 3 brightly illuminates the goods displayed on the lower side through the lighting case 33. Since the heat generated in each of the plurality of LEDs 342 is thermally conducted to the contact portion 352 of the heat dissipation member 35 through the heat dissipation layer 343, the heat is emitted to the outside through the plurality of heat dissipation plates 353. Overheating of the bulb 3 is prevented by the heat generated from the LED module 34.

On the other hand, as described above, when the socket 4 is installed in a horizontal state by screwing the socket 4 into the power connector 100 installed on the wall, the protruding connecting terminal 42 of the socket 4 is a spring (53). ) Is not compressed, the semi-circular support 22 of the bracket 2 may be inclined to one side without being horizontal when connected to the connection terminal at the inner end of the power connector 100. Since the protruding connecting terminal 42 protrudes from the end of the attachment portion 21 by a spring 53 at a predetermined interval (see FIG. 2), the protruding connecting terminal 42 is thus the spring 53. ) Is screwed into the storage space 24 while the screw connection terminal 41 can be further screwed into the power connector 100 until the end of the attachment portion 21 is reached. Therefore, the semi-circular support part can be installed by rotating the bracket 2 further by a predetermined angle in the screw tightening direction until the semi-circular support part 22 of the bracket 2 is horizontal, so that the semi-circular support part 22 is horizontal. The light bulb 3 mounted on the 22 is rotated in the direction of the center of gravity due to its own weight to brightly illuminate the goods displayed on the lower side.

In addition, when the lamp 3 is installed vertically on the power connector 100 installed on the upper surface of the showcase or the bottom of the shelf as shown in FIG. 5, the rotation of the semicircular support 22 of the bracket 2 is performed at this time. Possible light bulb (3) is installed in a state in which the light center (3) with the center of gravity is rotated to the lower side to illuminate the goods displayed on the lower side of the light bulb (3), and also the light (1) ), The installation angle of the semi-circular support part 22 of the bracket 2 on which the bulb 3 is mounted in the vertical installation of the power supply port 100 Since the bracket 2 can be further rotated at a predetermined angle in the state of being connected to the connection terminal of), it is possible to adjust the hemispherical support 22 by rotating it in a desired direction.

On the other hand, when the lamp 1 is installed in a horizontal or vertical state as described above, the bulb 3 automatically rotates toward the center of gravity due to its own weight to display the goods displayed on the lower side of the bulb 3. In order to change the illumination direction to a predetermined angle, the operator adjusts the illumination angle by screwing the illumination angle adjusting device 64 while rotating the bulb 3 installed to illuminate the lower side by its own weight at a desired angle. Pressing one free end of the semi-circular support 22 with the sphere 64 can be forcibly suppressed the rotation state of the ring member 31 so that the bulb 3 can be fixed in an inclined state to one side. As a result, the light bulb 3 can be illuminated in a desired direction.
