The socket member 110 includes a conventional spiral fastening part 112 coupled to a known light bulb socket and a power supply part, and a light bulb mounting part 116 having at least one terminal hole 114 formed therein.

In addition, each of the plurality of LED modules 120 is a plurality of LEDs 122 mounted to irradiate light according to the supply of electrical energy, electrode terminals 124 electrically connected to the power supply terminal of the terminal hole 114, A mounting passage 22, such as a power supply line for electrically connecting one LED module to another LED module, and a light diffusion window 140 for diffusing light from the plurality of LEDs 122.

Since the light diffusion window 140 has the same role and structure as the applicant's prior patent, detailed description thereof will be omitted.

The present invention, as shown in Figure 1 (a) by providing a joint portion 20, the detachment function of each LED module 120, as well as a plurality of LED module 120 provided in the LED bulb 100 ) To be connected to at least one or more by the joint portion 20 can be used by rotating the LED module 120 in a desired shape according to the situation or conditions required.

Therefore, the joint part 20 is mounted to the coupling part 10 formed on the opposite side of the LED module 120 on which the electrode terminal 124 is formed, and the joint part 20 includes at least one LED module 120. The connection is fixed. In addition, the joint part 20 communicates with a passage 22 through which a wire for supplying electrical energy is inserted into each of the LED modules 120 to be connected, and the LED module 120 in a position close to the coupling part 10. The shape is modified by the rotation of

That is, since each of the LED module 120 can be rotated in the required direction by the joint portion 20, the LED module 120 is modified in various forms according to the place or condition to be installed to irradiate light. It can be. For example, as illustrated in FIG. 1A, when three LED modules 120 are provided, the LED modules may have a substantially “U” shape to adjust illuminance in a desired direction.

In addition, the coupling portion 10 is preferably composed of an insertion protrusion 12 and the insertion groove 14 formed at a position corresponding to the passage 22, as shown in Figure 1 (b). At this time, the insertion protrusion 12 and the insertion groove 14 is formed only one in the middle portion of each LED module 120, the LED in a state in which each LED module 120 is coupled to each other by the coupling portion 10 It is also desirable for the module itself to be able to rotate.

Accordingly, the LED module 120 may be rotated forward and backward by the joint portion 20 to be deformed into a desired shape, and of course, due to the condition that each LED module 120 may be rotated by the coupling portion 10.

In addition, a stopper protrusion 26 is further formed on the top and bottom surfaces of the first coupling ring part 24 to prevent bending during rotation. That is, it is preferable that the LED module 120 has a rotation radius of about 270 ° so as to prevent bending away from the rotation radius, thereby enabling high reliability.

As a result, the present invention connects each of the LED modules 120 provided in the LED bulb 100 by the coupling part 10 and the joint part 20 in various forms. Not only can it be deformed, but if the LED direction is positioned in only one direction as necessary, it will have a condition that can be irradiated with high brightness.
