Description

LED lighting {LED lighting}

The present invention relates to an LED illumination light, and more particularly, to an LED illumination light which is capable of diffusing light by sliding an LED module including a plurality of LEDs in a diffusion tube, And the LED can be formed far away from the inner circumferential surface of the diffusion tube. The LED light can reduce the lightness of the components and improve the productivity, as well as the light transmittance due to the LED being illuminated.

Generally, the types of light sources used for illumination include fluorescent lamps, incandescent lamps, halogen lamps, and three-wavelength lamps.

Such conventional light sources are generally composed of a gas discharge tube which is used by injecting gas into a vacuum glass tube.

Such a gas discharge tube type light source may cause damage to the human body or air pollution due to the harmful gas if the glass tube is broken and the internal gas is leaked.

In recent years, development of an illumination lamp using a light emitting diode (LED) as a light source has been proposed as a technology for solving the problems of the conventional light sources and for green growth.

These LED lighting lamps have advantages of low power consumption, high brightness, and long life, compared to conventional lighting lamps, and thus have a high life and strong light emission.

The conventional LED fluorescent lamp of the related art includes an outer tubular member having light diffusion and coupling protrusions formed thereon as disclosed in Patent Application No. 10-2010-0113730 and a horizontal member having at least one or more lenses for diffusing the light source, And a heat sink attached to the lower end of the LED module and emitting heat generated from the LED to the outside.

 The heat dissipation plate has a coupling protrusion surface that discharges heat to an upper end of the heat dissipation plate and is coupled to an upper end fixing portion of the outer tubular material at the same time and a groove is formed at a lower end of the heat dissipation plate. And a piping-type heat-radiating outlet for discharging it to the outside is formed.

In addition, an LED module mounting surface to which the LED module is attached is formed at the lower end of the heat sink.

The horizontal lens has one end fixedly inserted into the recessed portion of the heat sink, and a pair of the horizontal lens is attached to the left and right sides of the heat sink. At least one lens is formed on the surface of the horizontal lens. So that the emitted light source can be diffused upward.

However, since the conventional general LED fluorescent lamp constructed as described above is composed of many parts such as the heat sink and the horizontal lens as described above, the entire weight of the LED fluorescent lamp is not only heavy but also the productivity is deteriorated due to many components There is no problem.

In addition, since the LED module is not fixed directly to the inner circumferential surface of the outer tubular member, but is fixed to the other end of the heat sink, the outer surface of which is fixedly coupled to the inner circumferential surface of the tubular member, The light diffusing point (light spot) distance is close to that of the external appearance material, so that the transmittance through which the light emission light passes through the external appearance material is inevitably lowered.
