TECHNICAL FIELD

The present invention relates to a method for sending or receiving, by a UE, data in a wireless communication system and, more particularly, to a method and apparatus for sending or receiving data using an unlicensed spectrum. The present invention relates to an LED lighting lamp with an enhanced heat dissipation function, and more particularly, an LED lighting lamp with an enhanced heat dissipation function, in which the LED lighting lamp is configured to be fitted into and connected to a socket, enables high temperature heat generated when LEDs are turned on to be rapidly dissipated to the outside through heat dissipation fins formed in a main body so as to have a further improved heat dissipation function, and allows simple assembly thereof so as to significantly improve productivity and repair workability.

BACKGROUND ART

In general, in an LED (Light Emitting Diode), electrical energy is directly converted into light energy. Accordingly, the LED is well known as a light source which has a low power consumption, has an excellent energy efficiency, emits excellent high brightness, and has a small and long lifespan as compared to light sources of the related art.

Accordingly, in recent years, various lighting lamps such as small LEDs which are compatible with the existing incandescent lamp fixed frame or 12V small halogen lamp fixed frame have been developed.

However, in the existing LED lighting lamp, even when the LED lighting lamp is operated with small watt (Watt), a high temperature of about 80° C. is generated. The high temperature is a direct factor to shorten a life of the LED lamp, and although the LED lamp has excellent advantages in terms of roughness compared to the existing incandescent lamp or fluorescent lamp, the LED lamp cannot be widely used.

Accordingly, an LED lighting lamp has been continuously developed to improve the heat dissipation function, and as an example, Korea Utility Model Registered No. 20-0455749 (LED lighting lamp having a heat dissipation function, and hereinafter, referred to as a “prior art”).

In the prior art, an LED lighting lamp is disclosed. The LED lighting lamp includes a conical outer case which is connected to a power source and houses a light source having an LED lamp and a PCB, a conical reflector which is detachably installed to be in contact with an inside of the outer case and reflects light of the LED lamp such that the light is emitted to the outside, and a fixing frame which is formed in a ring shape to have the same diameter as that of the reflector, is installed to be in contact with the outer case and the reflector, and detachably fixes a lighting lens located in front of the reflector in the outer case to the outer case, in which the outer case is formed of any one of ceramics, aluminum (Al), or cemented carbide having excellent thermal conductivity, and forms an umbrella-shaped rib to provide a heat dissipating hole for dissipating heat between the ribs.

However, in the prior art, there is a large number of parts, and thus, an assembly work is very inconvenient. In addition, productivity is lowered, and repair workability is also significantly poor.

In addition, in the prior art, the light source is installed deeply inside the outer case. Accordingly, high temperature heat generated during use cannot be rapidly dissipated to the outside and remains inside the outer case. Therefore, the LED lamp constituting the light source deteriorates, and there is a serious problem that a life of the LED light lamp is shortened.

DISCLOSURE

Technical Problem

The present invention is made to solve the above-described problems of the related art, and an object thereof is to provide an LED lighting lamp with an enhanced heat dissipation function capable of being configured to be fitted and connected to a socket and enabling high temperature heat generated when an LED is turned on to be rapidly dissipated to an outside through a heat dissipating fin formed in a main body to further improve the heat dissipation function.

Another object of the present invention is to provide an LED lighting lamp with an enhanced heat dissipation function capable of simply performing assembly between parts to largely improve productivity and repair workability.

Technical Solution

In order to achieve the above objects, according to the present invention, there is provided a lighting lamp with an enhanced heat dissipation function, the lighting lamp comprising: a main body which has a fitting hole formed inwardly through a center portion of an upper surface of the main body, a plurality of heat dissipating fins formed along an outer peripheral surface of the fitting hole, and a mounting surface formed on a lower portion of the main body, the mounting surface having a single annular heat dissipating groove or a plurality of annular heat dissipating grooves; an LED module which is installed to be in close contact with the mounting surface formed on the lower portion of the main body and has a plurality of LEDs installed on a bottom surface of the LED module; a cylindrical fastening boss which is fastened by means of a screw to the LED module, which is in close contact with the mounting surface of the main body, while being fitted and coupled through the fitting hole from an upper side of the main body; a connection portion which is fitted into and electrically connected to a socket provided on a ceiling, a wall surface, or the like while being fitted and fixed to an outside of an upper portion of the fastening boss; a lens holder which is fitted and coupled to the bottom surface of the LED module so as to be spaced apart therefrom by a predetermined distance and has lenses mounted at positions corresponding to the respective LEDs constituting the LED module so as to diffuse illumination light emitted from the LEDs and irradiate the illumination light; and a ring-shaped fixing cap which is coupled to a lower end of the main body and is fastened to the lower end by means of a screw while enclosing the LED module and the lens holder.

In the present embodiment, a guide groove is formed in a longitudinal direction at a position at which an inner peripheral surface of the fitting hole on the main body is divided by a predetermined angle, a guide protrusion having a fastening hole formed inwardly from a lower end of the guide protrusion is formed in the longitudinal direction on an outer peripheral surface of the fastening boss corresponding to a position corresponding to the guide groove, and a screw insertion hole is formed in each of the mounting surface on the main body and a surface of the LED module corresponding to the position corresponding to the fastening hole on the guide protrusion.

In the present invention, a plurality of air passages which communicate with the annular heat dissipating groove and through which external air flows into the heat dissipating groove or heat flowing into the heat dissipating groove flows to the outside are radially formed on the mounting surface on the main body.

In the present invention, the annular heat dissipating groove which is formed on the mounting surface on the main body is formed to protrude upward to have a depth being in contact with the heat dissipation fin.

In the present invention, a plurality of protrusion jaws for forming gaps through which external air flows into the ring-shaped fixing cap along an inner peripheral surface of the ring-shaped fixing cap are formed at regular intervals.

In the present invention, in order to couple the LED module and the lens holder to each other in a state where the LED module and the lens holder are separated from each other, a plurality of coupling holes are formed on an edge surface of the LED module, coupling protrusions fitted into the coupling holes are formed on an upper edge surface of the lens holder corresponding to positions corresponding to the coupling holes, and a supporting jaw which supports the edge of the coupling hole is formed at an intermediate portion of each coupling protrusion.

In the present invention, a cover which covers an upper edge of the fitting hole formed in the main body is formed at an intermediate portion of the fastening boss, and a plurality of heat dissipating holes are formed in an upper portion of the cover.

Advantageous Effects

According to the present invention, the LED lighting lamp with an enhanced heat dissipation function is configured to be connected to the socket, high temperature heat generated when an LED is turned on flows into the heat dissipating groove formed on the mounting surface of the main body, and thereafter, is rapidly dissipated to the outside through the heat dissipation fin formed on the outer peripheral surface of the main body and the heat dissipating hole formed in the cover on the fastening boss. Therefore, it is possible to further improve heat dissipation function.

Moreover, assembly between parts such as fastening of the LED module with respect to the mounting surface of the main body and coupling between the lens holder and the fixing cap is very simple. Accordingly, it is possible to largely improve productivity and to largely enhance repair workability to improve convenience in the use.
