Description
The present invention relates to an air-cooled LED lighting device, and more particularly to mounting a light emitting diode (LED) on a printed circuit board (PCB) and forming an air flow hole on the PCB, the LED is mounted PCB By mounting at least one fan (FAN) in the housing defining a, it relates to an air-cooled LED lighting device that can suppress the temperature rise around the LED by forcibly discharging the high temperature heat generated from the LED through the air flow hole .
In general, LEDs have advantages such as high lifespan, low power consumption, eco-friendliness, and thinning, and are used as lighting devices in various industrial fields.
These LEDs generate heat when they are driven and the light efficiency of the LEDs depends on the temperature. Conventional LEDs have a higher light output at a lower temperature when the light output is 100% at a constant temperature, for example, 45 ° C. As the temperature increases, light output decreases. Therefore, it is necessary to effectively dissipate the heat generated by the LED to extend the life of the LED.
Recently, various methods have been provided to dissipate heat generated by LEDs. For example, a heat sink is mounted adjacent to a PCB on which the LED is mounted, or a heat exchange medium is separately provided at the bottom of the PCB. The situation is equipped with a water jacket.
However, a conventional LED lighting device equipped with a heat sink cannot dissipate heat in a short time, so it is difficult to expect a sufficient cooling effect, and an LED lighting device equipped with a water jacket is a separate device for circulating heat exchange media. Since a device is needed, not only the manufacturing cost of the lighting device is increased, but also the weight of the lighting device itself is increased, so that it cannot be applied to various industrial fields.
The present invention has been made to solve the conventional problems as described above, an object of the present invention is to mount the LED on the PCB spaced apart, and to form an air flow hole in the PCB, the housing defining the PCB mounted LED By providing one or more fans in the air, it is to provide an air-cooled LED lighting device that can suppress the temperature rise around the LED by forcibly discharging the high temperature heat generated from the LED through the air flow hole.
In order to achieve the object of the present invention as described above, the present invention,
In the LED lighting device,
The first chamber and the second chamber are formed in the upper and lower portions by the diaphragm while dividing the inside up and down, a plurality of air inlet holes are formed in the first chamber, and at least one blower fan is mounted at one side of the second chamber, The diaphragm has a housing formed with a plurality of guide holes connecting the first chamber and the second chamber; And
The present invention provides an air-cooled LED lighting device including a PCB disposed in a first chamber and having a plurality of LEDs having a plurality of airflow holes formed thereon, and a plurality of LEDs spaced apart from each other at predetermined intervals on an upper surface of the PCB.
On the upper surface of the first chamber, a conventional diffuser plate made of an opaque material is mounted, and the air inlet is formed on either side or both sides of the first chamber.
In addition, the lower part of the PCB is provided with a plurality of PCB mounting blocks for mounting the PCB coupled to the first chamber, the PCB mounting block is mounted at a predetermined interval along the PCB, and the lower part of the PCB mounting block is It is seated in the first chamber to be spaced apart from the top, the mounting blades are formed to protrude on both sides of the PCB mounting block, the mounting groove is formed on the inner surface of the first chamber is inserted.
On the upper surface of the PCB mount block, an air flow groove communicating with the air flow hole is formed to settle to the lower side on the upper surface of the PCB mount block.
As described above, according to the present invention, an air-cooled LED lighting apparatus is mounted on a housing having a first chamber in which air inlets are formed and a second chamber in which a blowing fan is mounted, and a PCB and a PCB seated in the first chamber. By providing a lighting module having a plurality of LEDs, the stagnation in the first chamber can be easily discharged to the outside of the housing by driving the blower fan by driving the LED, thereby suppressing the temperature rise around the LED. There is an advantage that can extend the service life of the LED.
