Description

LED Panel and LED Lighting Apparatus of the Same Type {LED Panel and LED Lighting Apparatus of Bar Type Using the Same}

The present invention relates to a light emitting diode (LED) lighting device (hereinafter referred to as an LED) lighting device, wherein an AC power source applied from the outside is applied to a non-insulated type inside a housing through an LED panel by directly applying a fluorescent lamp socket. The present invention relates to an LED panel and a bar type LED lighting device that can be provided with a built-in power supply panel to ensure high insulation withstand voltage and improve assembly and productivity of the LED panel.

In the floodlight, landscape lighting, and advertising lighting market, various light sources such as fluorescent, neon, and halogen lamps have preoccupied in the past, but in recent years, LEDs are spotlighted as light sources in these fields. The reason why the LED is spotlighted as a light source is because of the device characteristics of the LED.

Conventional light sources emit light using mercury and the like, but LEDs are environmentally friendly because they do not use mercury, and maintenance costs are saved because they consume less power. In addition, the LED has a longer life than the conventional light source, excellent durability and robust characteristics.

In addition, the use of LEDs is being accelerated in that brightness and luminous efficiency are gradually improved and they are driven at low voltages, so that there is no risk of electric shock. In particular, it is widely used for outdoor and indoor lighting due to the applicability of LEDs and brilliant effects.

Representative indoor lighting devices include A-lamps with screw-type sockets, and LED lighting devices that replace light sources of straight fluorescent lamps (so-called fluorescent lamps) that use a luminaire (shade) with a pair of sockets installed at both ends. It is becoming.

Of these, the bar-shaped LED lighting device that replaced the fluorescent lamp with LED is divided into a product that can use a fluorescent lamp (shade) as it is and a product that uses a new lamp (shade).

Bar type LED lighting apparatus is disclosed.

However, although the LED light source is supplied with power input from the connectors formed at both ends of the power supply provided in the housing, the path input from the connector to the power supply is not disclosed. Since each assembly is assembled along the outer circumferential surface, there is a drop in assembly and productivity, there is no moisture-proof, dust-proof cover, there is a restriction according to the environment of the area used.

However, the LED lighting device has a structure for supplying power to the power supply device through a cable disposed inside the housing, thereby greatly reducing productivity when molding for waterproofing and insulation of the power supply device embedded in the housing. . In addition, since the LED lighting device is not a structure in which power input terminals are formed at both ends, the LED lighting device cannot be used as it is in a conventional fluorescent lamp.

In addition, when the LED portion coupled to the upper portion of the housing is formed to be screwed to form a screw coupling hole having a large diameter of about 2.2mm on the upper surface of the LED portion and the metal screw of the screwing hole is coupled if, When an AC power line for introducing one side AC power is arranged in the LED panel, there is a problem in that the insulation of the LED panel is greatly reduced.

Furthermore, Patent Publication No. 10-2009-78887 discloses a frame having a hollow portion, a light emitting means, a heat sink for transferring heat from the light emitting means to the frame, a transmission window covering the light emitting means and the heat sink, a power supply means for applying power to the light emitting means. A bar-shaped LED lamp having a has been proposed.

In addition, the application of power to the power supply means from the outside is made through a power connector disposed on one side of the LED lamp.

Therefore, the LED lamp does not have a structure capable of receiving external AC power through the existing fluorescent lamps.

In addition, the LED lamp uses a thermosetting resin to fix the light emitting means and the heat radiation fin to the connecting plate of the frame, there is a problem that the assembly productivity is inferior.
