Abstract
The present invention discloses an LED lighting device equipped with a plurality of substrates. In the LED lighting apparatus according to the embodiment of the present invention, a plurality of substrates on which the LED light source is mounted is mounted on the body in a state where a power line is inserted into the body, and each terminal formed on the power line and the plurality of substrates is provided with a screw or the like. Electrically connect using the power connection means.
According to the present invention, even when a plurality of substrates are mounted on the body, since the terminals of each board are directly connected to the power line, the LED light source is damaged due to the high power near the power input terminal as in the prior art, or the resistance heating of the circuit pattern is greatly reduced. As a result, the service life of the LED lighting device can be maximized. In addition, the work is very simple and convenient because the power is connected by simply fastening only the power connection means to the corresponding position. Therefore, even beginners can work as much as possible, which can greatly reduce labor costs, greatly improve work speed, and simplify maintenance work.
Description
The present invention relates to an LED lighting device such as a LED (Light Emitting Diode) fluorescent lamp, and more particularly, to an LED lighting device that can easily implement a power connection for a plurality of substrates.
LED is a semiconductor having a PN junction structure and is a light emitting device that converts electrical energy into light energy by recombination of minority carriers.
These LEDs consume less power, have higher energy efficiency, and have a longer lifespan than conventional fluorescent lamps or incandescent lamps. Therefore, their use range is rapidly expanding, especially for indoor and outdoor lighting devices or automobile lighting devices. .

Third, conventionally, the
The above-mentioned problems are not limited to the LED
The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a LED lighting device capable of maximizing the service life by preventing damage to the LED light source and reducing heat by improving the power connection structure.
It is also an object of the present invention to provide an LED lighting device that can adjust the electrical connection pattern of the LED light source mounted on each board according to the rated output of the DC converter.
In addition, the purpose of the present invention is to provide an LED lighting device that reduces the difficulty of the assembly process to reduce production costs and facilitates maintenance.
In order to achieve the above object, the present invention provides a plurality of substrates mounted on the one surface of the body having an insertion groove formed on one surface thereof, each of which includes a terminal mounted with an LED light source and electrically connected to the LED light source. A plurality of through holes formed at positions corresponding to the insertion grooves for each of the substrates, respectively, and are connected to the through holes of the plurality of substrates by being inserted into the insertion grooves of the body. As a means for electrically connecting a terminal and the power line, one end of the light source through the covering of the power line and the copper wire and the other end provides a LED lighting device comprising a power connection means for contacting the terminal.
In the LED lighting apparatus of the present invention, at least two pairs of through holes may be formed in each of the substrates. In addition, a plurality of insertion grooves may be formed, and the power line may be inserted into each of the plurality of insertion grooves.
According to the present invention, even when a plurality of substrates are mounted on the body, since the terminals of each board are directly connected to the power line, the LED light source is damaged due to the high power near the power input terminal as in the prior art, or the resistance heating of the circuit pattern is greatly reduced. As a result, the service life of the LED lighting device can be maximized.
In addition, the work is very simple and convenient because the power is connected by simply fastening only the power connection means to the corresponding position. Therefore, even beginners can work as much as possible, which can greatly reduce labor costs, greatly improve work speed, and simplify maintenance work.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
