The space 11 for accommodating the lamp may be a space for accommodating the light source used in the conventional street lamp. At least one side of the lamp housing 1 is opened and can be formed so that the operator can mount, replace and repair the lamp. As shown in Fig. 1, the bottom surface of the lamp housing 1 can be opened.

In the case of a streetlight, there is a lamp housing 1 and a lamp (not shown) at a height higher than a certain height from the ground by a support stand (not shown). Since the street lamp is generally provided for illuminating the ground, the bottom surface is opened to allow the light of the lamp installed in the upper part to be illuminated to the ground, and the opened bottom surface can be closed with the light- have. However, depending on the structure and use of the streetlight, there may be one or more faces including the bottom face of the streetlight, or a lamp housing 1 with one or more faces open, which is not the bottom face of the streetlight. Although the LED lamp fixing panel 6 according to the embodiment of the present invention is shown and described on the basis of the lamp housing 1 with its bottom opened, it can be applied to a lamp housing (not shown) have.

The LED lamp 5 may be formed with one or more LEDs. The LED lamp 5 can be fixed by the fixing panel 6 and housed in the receiving space 11 inside the lamp housing 1. [ The LED lamp 5 may be formed in a circular shape as shown in FIG. 1, but may be formed in various shapes within a size that can be accommodated in the lamp housing 1. The LED lamp 5 may include a radiating fin for emitting heat generated from the LED to the outside.

The LED lamp 5 may further include fastening means for fastening to the fixed panel 6. [ As an example, a plurality of first screw holes 51 communicating with the bolt holes 62 may be formed on the bottom surface of the LED lamp 5. The threaded hole 51 can be formed at a position corresponding to a plurality of fixed ribs 63 having a bolt hole 62 that extends further inward from the LED through hole 61 of the fixed panel 6 and penetrates vertically have. The LED lamp 5 can be fixed and fastened to the fixed panel 6 by fastening the fixing bolt 52 passing through the screw hole 51 and the bolt hole 62. [ Various types of fastening means capable of fastening the LED lamp 5 and the fixed panel 6 to each other can be employed in addition to the screw hole 51, the bolt hole 62 and the fixing bolt 52 described above.

The fixing panel 6 can be fastened to the lamp housing 1 such that the LED lamp 5 is fixed and the LED lamp 5 is mounted on the lamp housing 1 as described above.

The fixing panel 6 may have an outer circumferential surface which is in close contact with at least a part of the inner circumferential surface of the lower end of the space 11 of the lamp housing 1 so as to be fastened to the lamp housing 1. [ 1 to 2, the outer circumferential surface of the fixed panel 6 may be formed to coincide with the inner circumferential surface of the bottom surface of the lamp housing 1. In this embodiment, as shown in Fig. The fixing panel 6 can be fixed to the lamp housing 1 by a static frictional force because the outer circumferential surface of the fixing panel 6 coincides with the inner circumferential surface of the bottom surface of the lamp housing 1. [ In another embodiment, the outer circumferential surface of the fixing panel 6 need not exactly coincide with the inner circumferential surface of the lamp housing 1. [ Specifically, in the state that the fixing panel 6 is coupled to the lamp housing 1, at least a part of the outer circumferential surface of the fixing panel 6 is fixed to the inner circumferential surface of the lamp housing 1, The panel 6 may also be included in the scope of the present invention. For example, the outer circumferential surface of the fixing panel 6 may be formed in a shape having a protruding portion, and only the outer circumferential surface of the protruding portion may coincide with the inner circumferential surface of the lamp housing 1.

The fixing panel 6 may further include an LED through hole 61 so that the bottom surface of the LED lamp 5 can be exposed. As described above, one or more fixed ribs 63 may be formed on the inner circumferential surface of the LED through hole 61 to form the fastening means together with the screw hole 51 of the LED lamp 5.

As described above, a general lamp has a structure that is fixed to the lamp housing 1 by a socket. However, when replacing a common lamp with the LED lamp 5, it is easy to remove the socket and connect the connected power source, but there is no means for fixing the LED lamp 5. Accordingly, in the present invention, the fixing panel 6 is provided as a means for fixing the LED lamp 5.

As described above, the outer circumferential surface of the fixing panel 6 is in close contact with at least a part of the inner circumferential surface of the space 11 of the lamp housing 1, and can be fixed using the static frictional force. As a further embodiment, additional panel fastening means can be introduced for more firmly fastening the fastening panel 6 and the lamp housing 1, for example by fastening the lamp housing 1 and the fastening panel 6 A bolt, or a fixing clip may be added. Specific embodiments of the additional panel fixing means for more firmly fastening the fixing panel 6 and the lamp housing 1 will be described later with reference to FIGS.
