Screw Connecting type Light Emitting Diode Lamp Luminating Omnidirectionally}

The present invention relates to a screw-mounted LED lamp that emits light in all directions, and in particular, it is possible to irradiate light from the side as well as 360 degrees from the side, heat radiation profile heat transfer medium It is possible to efficiently heat dissipate, and to make the heat dissipation air flow path to circulate by forcing the outside air into the inside of the lighting lamp to increase the heat dissipation efficiency of the LED board further, and to increase the assembly workability. It relates to a screw-mounted LED lamp that emits light from all directions.

In general, a lighting device using a screw-type socket using an AC current typically has a merit that the light source is configured with a screw socket connection, such as a light bulb, and has a versatility free to attach and detach.

The lighting fixture using the AC current screw-type socket has a problem in that the energy efficiency is extremely low because the light bulb outputs only about 1/10 of the input electrical energy as light energy and loses a great amount of power.

In addition, in recent years, as a light source, a three-wavelength lamp with a significantly improved output efficiency compared to a light bulb is widely used in the form of a screw socket connection with a stabilizer. However, in the case of a three-wavelength lamp, since the glare is severe, the longitudinal circumference of the lamp is applied to a ceiling or a wall. It is installed in the shape of the recessed hole, and only the tip of the lamp is opened.

Therefore, when installed on the ceiling, since the light emitted and reflected only in one lower direction is used, there is a problem in that luminance is lost and light efficiency is lowered compared to that emitted in the 360 ° longitudinal direction.

On the other hand, LED (Light Emitting Diode) is smaller than the conventional light source and has a long life, and because the electric energy is directly converted into light energy, less power is consumed, has excellent energy efficiency and has a high-speed response feature.

Various lighting apparatuses using such LEDs as light sources have been disclosed, but since all of the structures are irradiated only downward, there is no technique for irradiating to the side, and since all of the heat dissipation structures use only heat dissipation members, there is a limit of heat dissipation efficiency.

The present invention has been created to solve the problems of the prior art as described above, the purpose of the screw-type LED lighting light emitted from all directions in the present invention,

Second, the heat generated from the side LED substrate is radiated through the heat dissipation profile and the first heat dissipation member, and the heat generated from the leading LED substrate is radiated through the second heat dissipation member and the heat dissipation profile, so that the side and end LED substrates are radiated. The heat generated from the heat dissipation profile as a heat transfer medium to allow more efficient heat dissipation,

Third, in addition to the first heat dissipation member and the heat dissipation profile, by separately introducing external air (that is, outside air) to the inside of the lamp forcibly to form a heat dissipation air flow path to improve the heat dissipation efficiency of the side LED substrate,

Fourth, the heat dissipation efficiency of the leading LED substrate can be further increased by sending external air forced to the leading LED substrate by the operation of the blower fan.

Fifth, the first cover plate, the first heat dissipation member and the support can be mounted to the housing by a single assembly process by the fastening rods, thereby improving the assembly workability.

Sixth, to provide a screw-integrated LED lamp that emits light from all directions to maximize the area in contact with the outside air by the unique geometry of the first heat dissipation member and the second heat dissipation member to increase the heat dissipation efficiency. There is.

First, the light can be irradiated 360 degrees from the side as well as the tip. As a result, the decorative aesthetics can be enhanced and the light can be irradiated downward and sideways simultaneously in one luminaire.

Second, the heat generated from the side LED substrate is radiated through the heat dissipation profile and the first heat dissipation member, and the heat generated from the leading LED substrate is radiated through the second heat dissipation member and the heat dissipation profile, so that the side and end LED substrates are radiated. The heat generated from the heat dissipation profile as a heat transfer medium has an effect that can be more efficiently radiated.

Third, in addition to the first heat dissipation member and the heat dissipation profile, the heat radiation efficiency of the side LED substrate can be increased by forming a heat dissipation air flow path that circulates by forcibly introducing external air (that is, outside air) into the lamp.

Fourth, it is possible to further increase the heat dissipation efficiency of the front end LED substrate by sending the outdoor air forced to the front end LED substrate by the operation of the blower fan.

Fifth, the first cover plate, the first heat dissipation member and the support can be mounted to the housing by a single assembly process by the fastening rod, thereby increasing the assembly workability.
