2. Description of the Related Art

In general, light bulbs used to light indoor space or used as a signalling means (for example, traffic lights, airplane taxi lights) use electrical energy which is converted into light energy. In the early days of the technology, neon lamp light bulbs using filaments were used. However, there were big problems in that, in the case of the neon lamp light bulbs, the manufacturing costs are low, but more input energy is converted to heat than converted to light, which makes the lifetime of the light bulb short and makes the energy consumption high.
Recently, in an attempt to solve the problem of short lifetime of said filament-using bulbs, fluorescent lamps and fluorescent integrated lamps using SMPS (Switch Mode Power Supply) used as driving power by converting externally-supplied AC power to DC power, have been developed. These bulbs have a larger proportion of electric energy converted into light energy than conventional light bulbs and thereby have advantages in terms of energy saving; however, it takes a long time to lighting and has a short lifetime. Accordingly, there is a need to develop a new, improved light source.
LEDs (Light emitting diodes) are developed to meet these requirements, and LED light bulbs have higher lighting efficiency than filament-using light bulbs, lower energy consumption, smaller size, lighter weight, longer lifetime, and lower maintenance costs, and the use of which has been increasing at a large rate. Prior patent publications regarding LED lamps are as follows.

SUMMARY

Lighting apparatuses having LED lamps include a lot of light emitting modules and a heat sink fin and also include an SMPS module to convert a common AC power supply to DC power for driving the LED lamps and supplying a stabilized power, which makes the LED lamps bulky and heavy.
Even though newly developed LED lamps are available, existing lamp apparatuses should be used as well. Accordingly, when trying to use the newly constituted LED lamps together with the existing lamp apparatus power supply socket, the LED lamps are only supported by the power supply socket, which is not very secure. This causes serious problems such as a breakage of the power supply socket during use especially in streetlamps experiencing vibrations. In addition, LED lamps are protruded as a whole due to the structure of the LED lamps protruding outside from the end of the power supply socket, which increases the volume of the lamp apparatus. As well, there are no LED lamps around the power supply socket of the lamp apparatus, this causes dark areas due to blind spots.
Accordingly, it is an object of the present invention to form the SMPS module separately from the lamp, to remove blind spots on the areas connected to the power supply socket, to decrease the protrusion of the LED lamp by accommodating the power supply into the LED lamp using a socket accommodating unit for accommodating the power supply socket outside the socket coupling terminal combined to the power supply socket of the LED lamp by the height of the power supply socket insertion while maintaining the overall volume of the LED lamp, and to support the LED lamp in directly adhering closely to the lamp apparatus.

The lamp body is may be a disc type, wherein the front surface is a light emitting module coupling surface to which the light emitting modules are coupled and is formed to be inclined backward from the center to the extension by evaginating the center from the extension and the rear surface is a surface on which the heat sink fin is formed and is formed to be more dented in the center than the extension, and the socket accommodating unit is formed such that an extra support flange is formed integrally around the socket coupling terminal formed at the center of the rear surface of the lamp body to be more protruded than the socket coupling terminal. Alternatively, the lamp body can be a tube type comprising an inner surface having a heat sink fin and an outer surface having a light emitting module coupling surface of at least 3 facets, the light emitting modules are attached to the light emitting module coupling surface, and the socket coupling terminal is installed on an indented spot by a length of the power supply socket installed on the lamp apparatus inside the tube in which the heat sink fin is formed to form the socket accommodating unit.
In addition, a wire connecting the socket coupling terminal screw-coupled to the power supply socket of the lamp apparatus and the plurality of light emitting modules are cut to be separate and connected with a coupling connector to make connection and separation operations of which easy.
According to the present invention, when a socket accommodating unit in which a power supply socket is inserted on the outside of the socket coupling terminal of the LED lamp is formed to be coupled to the lamp apparatus, there are advantages as follows: overall volume is minimized by accommodating the power supply socket in the LED lamp to decrease the protrusion of the LED lamp by the height of the power supply socket while keeping the total volume of the LED lamp unchanged; the support flange is directly adhered closely to the lamp apparatus to support the LED lamp, thereby maintaining a secure coupling state; and blind spots around the power supply socket are removed by constituting the light emitting modules to the part of the lamp body covering the power supply socket.

Accordingly, when the LED lamp is coupled to the lamp apparatus, the power supply socket 25 is inserted into the socket accommodating unit 13 of the LED lamp to make the LED lamp be closely adhered to and support the lamp apparatus 20.
At this time, the heat sink fin 12 formed on the rear surface of the lamp body 10 inclined backwards from the center to the extension is extended from the center to the extension such that the protruded end of the heat sink fin 12 is closely adhered to the lamp apparatus 20 to form an air channel 19 between the lamp apparatus 20 and the rear surface of the lamp body 10 when coupled to the lamp apparatus 20. The extra support flange 16 protruding more than the socket coupling terminal 15 around the socket coupling terminal 15 has a coupling protrusion 17 of a "¬" shape, and the lamp apparatus 20 has a corresponding coupling hole 21, which makes the lamp body 10 to be more firmly and securely fixed by the coupling thereof.

In addition, the lamp body 10 and the SMPS module 30 are formed separately, the SMPS module 30 is installed in the lamp apparatus 20 to supply rectified power to the power supply socket 25 installed in the lamp apparatus 20, and the lamp body 10 is only formed of the light emitting modules 14, heat sink fin 12, socket coupling terminal 15, and socket accommodating unit 13.
According to another exemplary structure of the present invention, the lamp body 10 is formed of a tube type comprising an inner surface having a heat sink fin 12 and an outer surface having a light emitting module coupling surface 11 of at least 3 facets, the light emitting modules 14 are attached to the light emitting module coupling surface 11, and the socket coupling terminal 15 is installed on an inwardly dented spot by a length of the power supply socket 25 installed on the lamp apparatus 20 inside the tube in which the heat sink fin 12 is formed to form the socket accommodating unit 13. Accordingly, when the LED lamp is coupled to the lamp apparatus, the power supply socket 25 is inserted into the socket accommodating unit 13 of the LED lamp to make the LED lamp be closely adhered to and support the lamp apparatus 20.
Now, embodiments of the present invention are described in detail.
First, an SMPS module 30 is installed to an existing lamp apparatus 20 or support 40 to install the lamp apparatus 20 which is constructed for the streetlamp or other lighting such that the power rectified and stabilized by the SMPS module 30 is applied to the power supply socket 25 of the lamp apparatus 20.
As the SMPS module 30 is separated from the LED lamp and installed on the lamp apparatus 20 or the support 40 to install the lamp apparatus 20, the weight and volume of the LED lamp decrease and the lifetime of the SMPS module 30 is extended as well.
After the installation of the lamp apparatus 20, the socket coupling terminal 15 formed in the center of the lamp body 10 constituting the LED lamp of the present invention is screw-coupled to the power supply socket 25 of the lamp apparatus 20 to combine the LED lamp to the lamp apparatus 20.
