Description

Floodlight with improved angle control and heat dissipation}

The present invention relates to a floodlight for brightly illuminating the surroundings at night by being installed in outdoor spaces such as airports, ports, sports facilities, parks, and parking lots, and more specifically, length control and left and right angle adjustment of floodlights, and floodlights The present invention relates to a floodlight with improved angle adjustment and heat dissipation function so that the rotation angle of the floodlight can be adjusted and heat inside the floodlight can be effectively radiated.

In general, in outdoor spaces requiring bright lighting at night, such as airports, ports, sports facilities, parks, and parking lots, lighting towers or lighting towers equipped with a plurality of luminaires have been installed and operated on the top of the posts.

A luminaire applied to such a lighting tower or a lighting tower is commonly referred to as a floodlight, and a total reflection type floodlight that utilizes the lighting angle of the built-in light source as it is, and an asymmetric type that refracts the lighting light so that it is concentrated in a desired direction. It is classified as a floodlight, and if necessary, a reflective cover called an irradiation angle limiting cover or a reflector is used in combination.

In addition, the above-described floodlights are manufactured and applied as floodlights each having various outputs depending on the purpose of installation, installation location, or installation conditions, and the floodlight having the best output by evenly considering the lighting range, brightness and uniformity. It is installed by reflecting the lights at the time of design.

Therefore, the existing floodlights have largely different shapes and structures, and their size varies according to various outputs, and according to the size of each output, the lighting body, the cover body, and the light source are manufactured separately and combined with each other. To produce.

In particular, in the general floodlight as described above, a fixing bracket made by bending a metal plate is coupled, and the fixing bracket is coupled to an elevating device such as a lighting tower or a lighting tower, or a fixing stand, and the light is transmitted from the fixing bracket. By arbitrarily adjusting the lighting irradiation angle of the lamp, it can be installed to produce accurate lighting in the desired direction and angle.

That is, the above-described angle adjustment structure for a floodlight or a lighting lamp is a radial toothed stopper device capable of controlling the binding part between the main body of the lighting fixture and the support body at a multi-level angle as shown in Utility Model Registration No. 20-0238537, and numerical values. As a result, an irradiation angle adjustment device consisting of a setting display unit capable of setting an accurate irradiation angle by a divided display scale has been devised and registered.

In addition, as in Registration Patent No. 10-0757756, the angle of the lighting installed on the raising and lowering carriers of the rail type elevating and descending lighting tower device is adjusted to the motor control at the position without the lowering operation of the elevating carrier and the gear coupling configuration that is combined with it. An angle adjustment device has been devised and registered so that the angle adjustment to the X and Y axis is automatically controlled by.

Then, as in Registration Patent No. 10-0992555, a first member is provided with a first coupling part at one end and a fitting part at the other end, and a second coupling part is provided at one end, and a connection part is provided at the other end. A second member, an angle adjusting member coupled between the first coupling portion and the second coupling portion to adjust an angle between the first member and the second member, and the first coupling portion, the angle adjusting member, the A device for adjusting the irradiation angle of a lighting device including a fixing member for fixing the second coupling part has been devised and registered.

In addition, as in Registration Patent No. 10-1553506, a bracket in which a first groove and a plurality of second grooves are formed so that the irradiation direction of the lighting device body can be easily and conveniently adjusted to a desired position, and inserted into any one of the plurality of second grooves. An LED lighting device having a structure including a fixing portion having a second protrusion and a first protrusion inserted into the first groove has been devised and registered.

Then, as in the Registered Utility Model No. 20-0482223, the user can properly adjust the irradiation angle of the lighting lamp in the direction desired by the user, and the adjusted irradiation angle can be firmly maintained so that the adjusted irradiation angle of the lighting lamp does not change arbitrarily. A case for LED lighting that can adjust an angle has been devised and registered.

As such, the angle control structures for conventional lighting fixtures and floodlights mostly have a serration engagement structure in the form of interlocking, and the serration engagement structure sets the rotation axis according to the bonding position between the multi-divided triangular protrusion and the triangular groove. It has the advantage that the irradiation angle of the lighting equipment or the floodlight can be adjusted to an equally divided angle.

However, in the case of the angle adjusting unit according to the serration engagement structure, an angle loss as much as the size occupied by the triangular protrusion and the triangular groove occurs, and thus fine precise angle adjustment is not achieved.

That is, since the serration engagement structure as described above plays the role of coupling and fixing the relatively heavy floodlight with the fixing bracket, it is typically formed with a division angle of 8-10° to prevent slip between the triangular protrusion and the triangular groove. Is common.

Therefore, the serration engagement structure has the advantage of accurately adjusting the angle for each section of 8 to 10°, but when the irradiation angle between these adjustment sections is required, the serration coupling portion has a closed end that cannot be adjusted. , When fine angle adjustment as described above is necessary, a pool plate or washer is added to the joint of the fixing bracket, which is not related to the floodlight, and angle adjustment is attempted at random, so uniform and precise angle adjustment of the irradiation angle is not made. There is a problem that cannot be done.

In addition, the conventional floodlight as described above has disadvantages such as damage to the circuit board inside the bracket due to heat radiated from the lamp, thereby increasing the cost of maintenance along with the disadvantage of not being able to use the luminaire itself. There was a drawback.

That is, a large amount of heat is generated from a plurality of lamps provided to irradiate light in the bracket, and this heat cannot be discharged smoothly (heat radiated) to the outside, and the circuit board has been damaged due to the temperature inside the bracket. There is a disadvantage that it is difficult to maintain that the substrate needs to be replaced.
