Description

{Landscape Lighting Lamp}

The present invention relates to an LED lighting device for a landscape illumination that emits light to illuminate a building, a building or a tree, and more particularly, to an LED lighting device for a landscape illumination that maximizes a range of light angle adjustment in a narrow space, And more particularly to a bar type LED lighting device for landscape illumination that can illuminate with a high degree of illumination.

Today, lighting fixtures are used not only as tools for illuminating the darkness but also for various purposes such as performing arts, interior and interior, as well as landscape lighting that illuminates the atmosphere of buildings, sculptures or trees.

In particular, the luminaire for the landscape lighting can be used to decorate and brighten the city's nighttime with light, to enhance the dignity of the city, and to create a beautiful night view.

These lamps for landscape lighting are usually installed in the gaps of ceilings, walls, floors, etc. so that the light source is not directly exposed to human vision, and the light source is reflected to the wall or reflector to indirectly illuminate the surroundings. have.

In addition, the direction and intensity of light can be adjusted by taking into consideration various conditions such as the inherent structure of the illumination object, the morphological characteristic, and the ambient light environment, so that a bright and sunny atmosphere, a profound and solemn atmosphere, a calm, mysterious and sacred atmosphere It is possible to create a completely different atmosphere and give images.

Accordingly, there has been proposed a luminaire for a landscape lighting capable of freely adjusting the direction and the illuminance of the light to the object to be illuminated by adjusting the installation angle to the ground or the wall.

For example, as shown in FIG. 1, a rotation operation and a tightening operation of coupling a main body 50 with a light source into a bracket 74 for fixing the main body 50 to a wall, floor, etc., The illumination direction and the illuminance of the light can be adjusted at a certain angle according to the tightening of the light source 83.

However, since the main body 50 can be rotated 360 degrees about the rotary shaft 82, it is inevitably subject to a considerable restriction on the range of adjustment of the light irradiation angle with respect to the object to be illuminated in a narrow space.

As another example, as shown in FIG. 2, a main body 2 having a light source built therein may be coupled to an illumination angle adjuster 6 mounted on the fixture 7 fixed to a wall, floor, or the like, Korean Patent Registration No. 10-0986716 discloses a landscape lighting device capable of adjusting the direction and the illuminance of light with a certain angle in accordance with the rotation operation of the illumination angle control device 6. [

However, since the rotation axis of the main body 20 and the angle of the illumination angle adjuster 6 are arranged at regular intervals, the radius of rotation is necessarily required to be adjusted by adjusting the angle of light irradiation , The angle adjustable range is reduced, and there is a limitation that it can not be installed in a place where the space is narrow.

Furthermore, when the LED is simply combined with a light source, unpleasant glare and eye fatigue are caused due to the light distribution characteristics of the LED that emits optically clear monochromatic light. Therefore, there is a problem in that it is not suitable as an emotional illumination for atmosphere production such as an interior or a landscape illumination.

Claims (5)

delete A heat dissipation support bar 100 having an LED module mounted on a bottom surface of an inner space having an opened upper surface and a rotary shaft 150 integrally formed at a lower portion thereof; A bearing portion 380 for supporting the rotation shaft 150 of the heat dissipating support bar 100 is formed on an upper surface of the heat dissipation support bar 100. A diffuser engagement groove 360 is formed in both longitudinal direction of the heat dissipation support bar 100, A heat dissipation case 300 in which cover engagement grooves 330 are formed in the longitudinal direction on both sides of the engagement groove 360 and joint grooves 320 are formed in the longitudinal direction on one side surface thereof; An electric motor for rotating the rotation shaft 150 of the heat dissipation supporting bar 100 within a certain angle range with respect to the heat dissipation case 300 so as to selectively adjust an irradiation angle of light emitted from the LED module; A diffuser 800 attached to an upper surface of the heat dissipation case 300 so as to smoothly diffuse the light emitted from the LED module and having protrusions 810 which are inserted into the diffuser engagement grooves 360 in the longitudinal direction on both sides of the lower end, ; The LED module is attached to the opening of the heat dissipation case 300 so as to transmit the light emitted through the diffuser 800 and is inserted into the cover engagement groove 330 of the heat dissipation case 300 in the longitudinal direction on both sides thereof A protective cover 400 having a coupling protrusion 410 formed therein; A bracket 500 for fixing and supporting the heat radiation case 300; A tilt joint 600 coupled to the bracket 500 so as to be angularly adjustable and having a locking protrusion 610 formed on one side of the bracket 500 to be fitted into a joint engagement groove 320 of the heat radiation case 300; And an and cap 700 which is inserted into and coupled to both ends of the heat radiation case 300 and the protection cover 400 in the longitudinal direction,
A protruding portion 810 continuously repeated in the longitudinal direction is formed on the surface of the diffuser 800 so that light emitted from the LED module is diffused up and down around the protrusion 810;
A boss 620 formed in the tilt joint 600 so as to correspond to the serration axis 510 and a screw hole 620 formed to communicate with the hollow of the boss 620 are formed in the bracket 500, Further comprising a screw (640) for tightening or loosening the serration axis (510) through the bracket (500) to adjust and maintain the installation angle of the tilt joint (600) with respect to the bracket (500) LED light fixture.
