Description

LED lamp for LED light-emitting part detachable socket {LED lamp for socket}

The present invention relates to an LED lamp for a socket, and more particularly, a lamp body having a light emitting part for emitting light by an LED and a power supply for emitting light of an LED as an LED lamp used to be mounted on an existing lamp socket. It relates to an LED lamp for the socket to be separated.

Various types of lamps are used to provide light or to illuminate a desired part at night or indoors. These lamps are powered to convert the electrical energy into light energy to provide light or to illuminate the desired portion, generally used incandescent bulbs or fluorescent lamps.

However, although incandescent bulbs generate more heat than light and thus can be manufactured inexpensively due to low light efficiency of about 15%, the use of incandescent bulbs has recently been avoided. Fluorescent lamps have an advantage of energy saving due to higher light efficiency of converting electrical energy into light energy than incandescent lamps, but have a long time required for lighting and short lifespan, and have a problem of using harmful gases to the environment.

Recently, a light emitting diode (LED) has been developed and used, which uses a phenomenon of emitting light when a current flows through a semiconductor, and its history has been around for decades, but recently, a white light source for lighting can be realized. Although it is still less economical in terms of cost, it can achieve high light efficiency of nearly 85% with a small power and a lifetime of more than 50,000 hours.

Therefore, LED lamps not only extend the life of lighting fixtures and greatly improve energy efficiency, but also reduce power consumption by more than 80% compared to incandescent lamps and more than 50% compared to fluorescent lamps. It will also play a part in reducing this. Due to these expectations, various LED lamps have been developed and used to replace incandescent lamps or fluorescent lamps.

However, LED lamps used as replacements for incandescent lamps have a number of problems since the light emitting unit for emitting light by the LEDs and a lamp main body having parts for supplying power to the LEDs are integrated.

First, since the light emitting portion and the lamp body are integrated, there is a restriction on their size and shape. In order to integrate the light emitting unit and the lamp body, the size of the light emitting unit must be matched to the size of the lamp body, and the shape of the lamp body and the light emitting unit has to be designed in consideration of the connection of the lamp body and the light emitting unit.

Next, since the light emitting part and the lamp body are integrated, the life of the LED of the light emitting part is relatively long, but the life of the parts that enter the lamp body does not follow this, so that the life of the entire LED lamp is not the life of the LED. The long life, which is an advantage of the LED, becomes meaningless since it is determined by the life of the parts to be entered.

In addition, since the light emitting part and the lamp body are integrated, the direction of the light emitted from the light emitting part is determined according to the direction in which the lamp body is mounted in the socket. Therefore, since the direction of light from the light emitting unit is determined according to the direction in which the socket is installed, there is a problem in that light cannot be irradiated in various directions.

Lastly, in the conventional LED lamp in which the light emitting unit and the lamp body are integrated, a separate heat sink must be provided to discharge heat generated from the light emitting unit to the outside. However, such a heat sink causes a cost increase in designing and manufacturing the LED lamp.

A socket coupling portion 34 is coupled to the coupling flange 32. The socket coupling portion 34 has a cylindrical shape and a screw portion is formed on an outer surface thereof so that the socket coupling portion 34 may be mounted in a socket to which a general incandescent lamp is mounted, that is, a socket installed in a lamp housing 60 or the like as shown in FIG. It can be inserted and fastened to the 62. The outer surface of the coupling flange 32 is installed in close contact with the ring-shaped rubber pad 36, the rubber pad 36 is the socket coupling in the socket 66 Part 34 serves to prevent the easy fall out because of the total weight of the LED lamp.

As shown in FIG. 4, the connection bracket 40 has a main body portion 42 longer than a width, and the main body portion 42 has a long coupling hole 44. The coupling hole 44 is a portion through which the fixing bolt 40 'passes, and the length of the main body portion 42 is longer than the diameter of the fixing bolt 40'. This is to adjust the position in which the connecting bracket 40 is fixed to the fixing nut 28. A coupling recessed portion 46 is formed on a surface of the main body portion 42 corresponding to the periphery of the coupling hole 44. The coupling concave and convex portion 46 is coupled to the concave and convex portion 29 of the fixing nut 28 to prevent the connection bracket 40 from flowing to the fixing nut 28. For reference, the coupling hole 44 is not necessarily in the form of a long hole may be formed of a plurality of garden.

Both ends of the main body portion 42 is provided with a coupling piece (48). The coupling piece 48 is formed to be orthogonal to the end portion of the body portion 42. A through hole 48 'is drilled in the coupling piece 48 so that the fixing bolt 40' passes through it. The coupling piece 48 is not necessarily present at both ends of the main body portion 42, but may be present only at one end. In addition, the coupling piece 48 may be provided with a coupling recessed portion 46 around the through hole 48 ′.

The LED light emitting unit 50 includes a plurality of LEDs 54 mounted on the substrates 52 and 52 '. In this embodiment, the base substrate 52 is formed in a hexagonal plate shape, and the wing substrate 52 'is inclinedly connected to six sides of the base substrate 52, respectively. Of course, the wing substrates 52 'are also connected to each other. In the present embodiment, the wing substrate 52 'is trapezoidal in shape. As such, the wing substrate 52 ′ is inclinedly connected to the base substrate 52, so that the direction in which light is radiated can be made wider, and a separate reflecting plate does not need to be used.

A through hole (not shown) is drilled through the central portion of the base substrate 52, and the fixing bolt 40 ′ penetrates and is coupled to the coupling piece 48 of the connection bracket 40. If no thread is formed on the inner surface of the through hole 48 'of the coupling piece 48, a nut is required to fasten the fixing bolt 40' to the coupling piece 48.

The light emitting unit wire 56 is used to supply power to the LEDs 54. One end of the light emitting part wire 56 is electrically connected to the substrates 52 and 52 ', and a light emitting part connector 58 is provided at the other end thereof to the cover connection connector 30 provided in the cover 22. Combined.

Meanwhile, the LED lamp of the present invention may be directly mounted and used as a socket for an incandescent lamp in the state shown in FIG. 1, but as shown in FIG. 2, the socket 66 installed inside the separate lamp housing 64. The socket coupling portion 34 of the lamp body 10 is coupled to the lamp housing 10, and the inner space of the lamp housing 64 is covered by a separate lamp cover (not shown) covering the lamp housing 64. Can be used as The lamp cover is generally translucent.

Hereinafter will be described in detail the use of the LED lamp for LED light-emitting portion detachable socket according to the present invention having the configuration as described above.

LED lamp of the present invention is made so that the lamp body 10 and the LED light emitting unit 50 is made separately and connected to each other by the connection bracket 40. At this time, the direction in which the LED light emitting unit 50 can irradiate light varies according to the connection state between the connection bracket 40, the lamp body 10, and the LED light emitting unit 50.

FIG. 5 illustrates that the LED light emitting unit 50 faces a direction perpendicular to the direction of the lamp body 10. Accordingly, the fixing bolt 40 'penetrates the coupling hole 44 of the connection bracket 40 and is fastened to the fixing nut 28 of the cover 22. At this time, the coupling concave and convex portion 46 of the connecting bracket 40 and the concave and convex portion 29 of the fixing nut 28 are coupled to each other so that the relative movement between the connecting bracket 40 and the fixing nut 28 does not occur. do.

In this case, the main body 42 of the connection bracket 40 is brought into close contact with the surface of the cover 22. At this time, the coupling piece 48 at one end of the main body portion 42 of the connecting bracket 40 protrudes from the main body case 12 and extends. The coupling piece 48 is coupled to the fixing bolt 40 'penetrating the through hole of the base substrate 52 of the LED light emitting unit 50. As such, the state in which the LED light emitting unit 50 is coupled to the main body case 12 by the connecting bracket 40 is illustrated in FIG. 5.

In the state shown in FIG. 5, light emitted from the LED 54 of the base substrate 52 is irradiated in a direction orthogonal to the direction in which the tip of the socket 62 faces, and the LED 54 of the wing substrate 52 ′ is irradiated. The light emitted from the light is inclined by the inclination of the wing substrate 52 '. In the state of Figure 5 slightly loosen the fixing bolt 40 'fastened to the fixing nut 28 to rotate the connecting bracket 40 to adjust the direction toward the LED light emitting unit 50, and then fixed again The direction of the adjusted LED light emitting unit 50 may be fixed by fastening the bolt 40 ′.

Next, in Figure 6, the coupling body 48 provided at each end of the main body portion 42 of the connecting bracket 40, respectively, to the cover 22 and the LED light emitting unit 50 by combining the lamp body 10 The direction toward which the LED light emitting part 50 faces is shown in the same direction.

In this case, light emitted from the LED 54 of the base substrate 52 is mainly irradiated in the direction toward which the tip of the socket 62 faces, and light emitted from the wing substrate 52 'is inclined by the wing substrate 52'. The light is mainly irradiated in the inclined direction.

On the other hand, in the coupling of the coupling bracket 40 and the fixing nut 28, the coupling between the coupling uneven portion 46 and the uneven portion 29 is the relative between the coupling bracket 40 and the fixing nut 28 Since the movement is blocked, even if the weight of the LED light emitting unit 50 is heavy, the position of the LED light emitting unit 50 is not changed. In addition, the rubber pad 36 serves to prevent the state in which the LED lamp is mounted on the socket 62 not easily released.

When the LED lamp is coupled to the socket 62 in the state shown in FIGS. 5 and 6, power transmitted through the socket 62 is transferred to the ballast substrate 20 to be used in the LED 54. Made to fit. The cover connection wire 20 'and the light emitting part wire 56 are transferred to the substrates 52 and 52'. The power transmitted in this way allows the LED 54 to emit light.

Referring to the separation of the lamp body 10 and the LED light emitting unit 50, first, by loosening the fixing bolt (40 '), the connecting bracket 40 and the LED light emitting unit 50 and the connecting bracket 40 ) And the fixing nut 28, that is, the coupling between the lamp body 10 is released. Next, the light emitting unit connector 58 at the tip of the light emitting unit wire 56 is disconnected from the cover connection connector 30 to disconnect the electrical connection.

In this state, for example, if it is necessary to replace the ballast substrate 20, or if the entire lamp body 10 needs to be replaced, replace it with another one to the LED light emitting unit ( 50) can be used in combination.

The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.

For example, although the shape of the body portion 42 of the connecting bracket 40 is longer than the width is formed, the width is different from the configuration shown in various configurations, such as different depending on the position of the body portion 42 This is possible.

In addition, in the present embodiment, the uneven portion 29 is formed in the fixing nut 28 and the coupling uneven portion 46 is formed in the corresponding portion of the connecting bracket 40, but the fixing nut 28 and the connecting bracket The uneven part 29 and the combined uneven part 46 may be formed only on one side of the 40.

The basic substrate 52 constituting the LED light emitting part 50 was a hexagonal plate in this embodiment, but need not necessarily be a polygonal plate. For example, in the case of a triangular plate, the wing substrates 52 'may not be connected to each other. When the base substrate 52 is a plate shape of square or more, the wing substrates 52 'may be connected to each other. Of course, this depends on how to design the installation angle of the wing substrate (52 ').

In addition, the wing substrate 52 'may be trapezoidal to be connected to each other while being inclined without being orthogonal to the base substrate 52.

The LED light emitting unit 50 may use only the base substrate 52 without the wing substrate 52 '. This is a case where light irradiation does not matter even in only one direction. At this time, the base substrate 52 may be a plate having a variety of shapes.
