In addition, terms used in the contents and claims of the present invention should be construed as meanings consistent with the technical spirit of the present invention. Therefore, the scope of protection or scope of the present invention is not limited to the following embodiments.

First, with reference to the accompanying drawings, Figure 1 is an exploded perspective view showing a state before the floodlight cover is mounted on the front side of the main body as an incandescent lamp type LED lamp according to a first embodiment of the present invention, Figure 2 1 is a cross-sectional perspective view showing only a part of the incandescent lamp type LED lamp in which the floodlight cover is coupled to the main body front side.

In addition, Figure 3 is an exploded perspective view showing a part of the state before the floodlight cover is mounted on the main body front side of the incandescent lamp type LED lamp according to a second embodiment of the present invention.

As shown in these figures, the incandescent lamp type LED lamp having excellent assembly and maintenance characteristics according to the first and second embodiments of the present invention, the aluminum body main body 10 and a plurality of LEDs 21 Is composed of an LED circuit board 20, a synthetic resin floodlight cover 30, an SML circuit board 40 on which various electric elements are disposed, a synthetic resin connector 50, and a metal base 60. have.

Looking at each of the above components in more detail, first, the main body 10 according to the first embodiment of the present invention, made of aluminum having excellent thermal conductivity, the heat dissipation area, that is, to increase the contact area with air To this end, a plurality of cooling fins 13 are integrally formed on the circumferential wall, and a transverse plate 11 is provided on the upper side of the inner space surrounded by the circumferential wall so as to block the inner space. A hole through which an electric wire can pass is drilled in the center of the cross plate 11, and an inner wall 12 protrudes from an edge portion of the cross plate 11 at a predetermined distance from the circumferential wall. The height of protrusion of the inner wall 12 is shorter than the height from the top of the circumferential wall to the surface of the transverse plate 12. In addition, at least two or more openings 15 are formed in at least two places of the inner wall 12, the inner wall of which is partially cut off, and faces the opening 15 so that at least two locking protrusions are formed on the inner side of the circumferential wall. 14) is formed. In addition, although not shown in the figure, a fitting engagement portion of the same / similar form as that disclosed in the applicant's prior application model is formed on the lower side of the main body 10.

On the other hand, in the main body 10 according to the second embodiment of the present invention, the slit 16 is formed instead of the locking projection 14 of the first embodiment.

Next, the LED circuit board 20 mounted on the cross plate 11 is fixed with screws to facilitate disassembly and assembly with the cross plate, and a wiring hole is drilled in the center thereof. In addition, a plurality of LEDs 21 are arranged around the wiring holes.

Next, the floodlight cover 30 produced in the shape of a hemispherical shape or a magnetic tube (glass tube of an incandescent bulb) by injection blow molding is formed with a locking projection 14 or a slit 16 formed on the front side of the main body 10. ), Two or more hooks 31 having a width not larger than the opening width of the opening 15 protrude downward from the bottom surface. The number of hooks 31 is preferably equal to the number of catching protrusions 14 and slits 14, but is not limited thereto. Further, along the lower end surface of the floodlight cover, a reinforcing rib 32 having a low height protrudes between the hooks 31.

Thus, by making the width | variety of the hook 31 smaller than the opening width of the opening part 15, when attaching a floodlight cover to the front side of a main body, it becomes easy for the hook 31 to enter inside the front side of a main body. In addition, when the hook 31 is hooked to the slit 16, the flat head screwdriver is inserted into the slit 16 to easily push the hook 31, so that the main body and the light emitting cover can be easily disassembled.
