Description
The present invention relates to an LED lighting device, in particular, by having a prefabricated heat dissipation fin that is assembled after assembling and assembled in the screw-type socket of the outer casing, the size of the heat dissipation fin can be freely formed free from the space constraints of the outer casing, moreover, natural ventilation By installing in the form of a wire coil exposed to this space, the heat dissipation performance is significantly improved, and the outdoor LED lamp for heat dissipation and heat dissipation of the high-power LED light source quickly and smoothly and maximally improves the lighting quality.
LEDs (Light Emitting Diodes) have longer lifespans than conventional light sources, and because electrical energy is directly converted into light energy, they consume less power, emit high brightness with high energy efficiency, and have high-speed response characteristics. Luminaires using light sources have been developed in various ways from general home use to vehicle use and outdoor use.
In general, a street lamp, which is one of outdoor lighting fixtures, is usually provided with an outer casing on a support having at least one arm in the form of a memory or a T, and a lamp is installed in the outer casing.
The
On the other hand, when the LED is turned on heat is generated, if the heat dissipation is not smooth, the LED life is shortened and the illuminance is lowered, so the above advantages of the luminaire using the LED presupposes the condition that the high heat of the LED is radiated smoothly.
The outdoor LED lamp according to the related art is a screw-type type of light source unit in which a plurality of LEDs are installed in a PC, heat dissipation means bonded to the PC, and supporting the light source unit and the heat dissipation means and corresponding to a threaded socket of an outer casing. It is composed of a casing coupling member having a power connection.
And the heat dissipation means is provided with a heat dissipation fin integrally to the body bonded to the PCB to form a heat exchange area.
By the way, the inner space of the outer casing in which the LED lamp is accommodated in the street lamp is formed to a low height, the heat radiation fins integrally formed in the body is formed within the allowable height of the inner space of the outer casing.
This is because when the heat dissipation fins are largely formed, the heat dissipation fins are caught on the ceiling of the outer casing when they are coupled to the threaded
Thus, in the prior art, since the heat dissipation means is integrally formed with the body and the heat dissipation fins, the size of the heat dissipation fins is limited within the range in which the heat dissipation fins can be assembled to the outer casing. Since it is not installed in the inner space, the heat dissipation performance is not supported, which shortens the life of the LED and reduces the light quality.
The present invention has been made to solve the above problems,
An object of the present invention is to provide a prefabricated heat dissipation fin that is assembled after assembling and assembled in the screw-type socket of the outer casing, the size of the heat dissipation fin can be freely formed free from the space constraints of the outer casing, and furthermore the wire coil in the space where natural ventilation It is to provide outdoor LED lamps that can heat dissipate heat of high power LED light source quickly and swiftly and smoothly, maximize the life of LED and significantly improve the lighting quality by dramatically improving heat dissipation performance.
It is another object of the present invention to provide an outdoor LED lamp for remarkably simple and easy adjustment of the LED lamp irradiation direction.
Outdoor LED lamp according to the present invention to achieve the above object
A light source unit including at least one LED (Light Emitting Diode) 11 and the LED mounted PCB and the LED mounting PCB, the heat dissipation means for dissipating the heat of the light source unit and supporting the heat dissipation means and the power connection is provided An LED lamp comprising a casing coupling member and coupled to a prop fixed outer casing,
The heat dissipation means includes a body in contact with the light source unit PC, and a heat radiation fin (assembled heat radiation fin) coupled to both sides of the lower body,
The prefabricated heat dissipation fins are characterized in that the LED lamp is assembled after being assembled to the threaded socket of the outer casing.
Outdoor LED lamp according to the present invention having the above configuration
By providing a prefabricated heat dissipation fin that is assembled after being assembled and assembled in the screw-type socket of the outer casing, the size of the heat dissipation fin can be freely formed free from the limitations of the space of the outer casing. By dramatically improving the heat dissipation performance, the heat of the high power LED light source is quickly and smoothly dissipated, maximizing the life of the LED, and the lighting quality is remarkably improved.
In addition, there is an advantage that the adjustment of the irradiation direction of the LED lamp is very easy and easy.
