Description

LED lighting system {LED lighting system}

The present invention relates to an LED lighting device, and more particularly, to an LED lighting device that can illuminate indoors or outdoors using high brightness LED.

In general, the lighting device is installed on the ceiling or wall of the room, street lamps or signs of the street and serves to illuminate the interior space or the surrounding area.

Such a lighting device is manufactured in a predetermined shape such as a rectangle or a circle, and has a space part having a predetermined depth therein, and is connected to a case body mounted on a ceiling or the like by a separate fastening means, and connected to an internal socket of the case body to control a user's switch. The lamp is controlled to be turned on, and a cover is coupled to the case body while closing the lower part of the lamp to transmit the light emitted from the lamp to the interior space.

However, conventional lighting devices have a disadvantage in that power consumption is severe, short lifespan, and low illuminance due to mainly using lamps such as fluorescent or incandescent lamps.

Accordingly, in recent years, a lot of bright and long-life LEDs with relatively low power consumption have been applied to lighting devices.

Usually, the LED is an electronic component that produces a small number of carriers (electrons) injected using a p-n junction structure of a semiconductor and emits light by recombination of these minority carriers.

These LEDs are not only compact and have a long life compared to conventional light sources, but also have low power consumption and good efficiency because electrical energy is directly converted into light energy.

In addition, LEDs have high-speed response and are widely used in display lamps and numeric display devices of various electronic devices such as display devices for automobile instruments and light sources for optical communication, and for homes, vehicles, ships, traffic signals, various guide lamps, It is applied to various lighting means such as evacuation induction lamps.

However, existing lighting devices using LEDs are not only applied in a simple structure, but also need to be technically and structurally improved to improve luminous efficiency, such as no multi-angle processing for reflecting LED light. It's happening.

In addition, existing LED lighting devices are installed in a state of being electrically connected to a predetermined position on a printed circuit board on which a plurality of LED elements are separately provided, and the back surface of the printed circuit board on which each LED element is installed is usually made of aluminum. It consists of a heatsink which is attached and configured to radiate heat generated from each LED element to the outside when it is turned on.In this case, the overall heat shear efficiency is very low because the heatsink is attached to the back of the printed circuit board. The disadvantage is that it does not quickly dissipate heat generated from each LED device to the outside.

In addition, the existing LED lighting devices are inefficient as well as wasteful elements, such as the need to newly manufacture and replace the entire lamp assembly due to the lack of compatibility with existing facilities when replacing the lamp.

Accordingly, the present invention has been made in view of the above, by implementing a new type of lighting means that take a rectangular shape as a whole, while combining and combining the unit LED unit having a plurality of LED elements in parallel in a variety of structure forms The purpose of the present invention is to provide an LED lighting device that can be applied as well as improve luminous efficiency.

In addition, the present invention implements a new type of heat dissipation means that takes one-to-one correspondence to each LED element and generally takes one rectangular block shape, thereby effectively dissipating heat generated from the LED elements to the outside, resulting in deterioration of various functional elements. Another object of the present invention is to provide an LED lighting device that can prolong the life of components and lighting by preventing problems.

In addition, the present invention by manufacturing the socket portion of the lighting means in the same structure and specifications as the socket portion of the existing lamps, such as incandescent lamp, when replacing the lamp can be replaced only the lamp portion while utilizing the existing facilities as it is, Another objective is to provide an economical and efficient LED lighting device in terms of cost.

In order to achieve the above object, the LED lighting device provided in the present invention includes a socket portion for connecting the power side, a heat dissipation portion for heat dissipation, an illumination portion for illumination disposed under the heat dissipation portion, and a cover portion for closing the lower portion of the illumination portion. In particular, the lighting unit is arranged in a convex curved shape at the same time arranged side by side at a predetermined interval along the left and right width direction of the unit LED unit consisting of a plurality of LED elements arranged in a row. It is made of a rectangular shape as a whole, it is characterized by being able to secure a wide irradiation angle in the downward direction.

Here, the heat dissipation unit is configured in the form of a square block having a plurality of heat dissipation fins protruding in a grid-like arrangement structure on the top, and the bottom portion of the square block provides a heat dissipation surface in direct contact with each unit LED unit, LED element It is desirable to be able to quickly and effectively release the heat generated from the outside to the outside.

LED lighting device provided by the present invention has the following advantages.

First, the unit LED unit is a combination of a plurality of LED elements arranged in a number of lines, not only can realize a variety of shapes of the LED lighting device, but also greatly improve the luminous efficiency, such as for home, vehicle, decorative, It can be used for various purposes according to the purpose of use of lighting equipment according to traffic signal and induction lamp.

Second, by eliminating the uniform LED lighting device of the existing long bar shape and implementing a new shape of the square, the appearance of the LED lighting device can be improved.

Third, by applying a heat sink having a rectangular block shape corresponding to each LED element one-to-one, the heat generated from the LED element can be quickly discharged to the outside, thereby greatly extending the life of components and lighting.

Fourth, by applying the socket of the same structure and standard as the socket portion of the existing lamps, such as incandescent lamps, it is possible to replace only the lamp portion by utilizing the existing facilities as it is, and therefore economical and efficient in terms of cost.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
