Abstract

The present invention relates to an LED lamp having a plurality of light source modules, in which the LED lamp is provided with a socket receiving portion to receive a power socket such that the LED lamp is brought into direct contact with a lighting equipment to be stably engaged thereto, and in which a switch mode power supply (SMPS) is separated from the lighting equipment to reduce volume and include more light source modules with no dead zone. The LED lamp includes: a heat radiation pin formed on a lamp body and a socket connecting terminal formed on the center of the heat radiation pin to be threadedly engaged with the power socket, and the heat radiation pin is provided with a plurality of light emitting modules such that the light emitting modules are turned on by the power rectified by the SMPS. The center of the lamp body is provided with a socket receiving portion to receive the power socket of the lighting equipment adjacent to the socket coupling terminal such that the power socket is inserted in the socket receiving portion and is closely supported by the lighting equipment. When the LED lamp is coupled to the lighting equipment, the entire volume of the lamp is equal, but since the power socket is received in the LED lamp, the protruding height of the LED lamp is reduced by the height of the power socket, thereby minimizing the entire volume. Since the support flange is brought into direct contact with the lighting equipment, the LED lamp is supported thus maintaining a stable engaged state. Since the light emitting module is provided at the portion enclosing the power socket of the lamp body, the dead zone adjacent to the power socket is eliminated.

Generally, a light bulb used as a signal means (for example, a traffic light or an aircraft guide) illuminating an interior or applying light is used to convert electric energy into light energy. In the beginning, an incandescent lamp using filament There is a problem that the life of the bulb is short and the energy used is large because the energy used instead of the low cost is converted into the exothermic energy more than the energy converted to the light source.

In recent years, in order to solve the problem of the short life of the filament lamp, there has been proposed a switch mode power supply which converts AC power supplied from the outside into direct current (DC) electricity and uses direct current power as a driving power However, it also has the advantage of energy conservation because it has a larger ratio of converting electric energy into light energy than bulb. However, it requires a new medium due to the long time required for lighting and the short life span .

The LED light bulb is a light emitting diode (LED) which is developed to meet this demand. The LED bulb has advantages such as high luminous efficiency, low power consumption, small size, light weight and long maintenance life. The use of the LED lamp has been increasing explosively. The patent literature of the prior art for the LED lamp developed so far will be described as follows.
