Description
The present invention relates to an LED lighting device, and more particularly, to an LED lighting device that can be used for lighting, such as a street lamp, the lighting angle can be adjusted and excellent heat dissipation efficiency.
In general, a lighting device includes a light source and emits light by illuminating a light emitted from the light source to a predetermined range. Examples of the lighting device may be a street lamp installed on a street lamp post, a lamp used to be installed on a wall or ceiling of a building.
Incidentally, incandescent lamps, fluorescent lamps, three wavelengths, and the like are generally used as light sources of the lighting device, but they have disadvantages such as high power consumption and short lifespan. In order to remedy this drawback, recently, a technology that uses a liquid light-emitting diode (LED), which consumes relatively little power and has a long life, is drawing attention.
The lighting device using the LED as a light source has advantages of low power consumption and long life, but high cost heat radiation has emerged as a problem.
In addition, the LED is excellent in the straightness of the light, but because of the poor diffusion properties of the lighting device using the LED is a disadvantage that the irradiation range of the light is not wide. This narrow range of irradiation is a barrier to using LEDs as lighting devices, such as street lights.
Therefore, the problem to be solved by the present invention is to provide an LED lighting device excellent in heat dissipation.
In addition, to provide an LED lighting device that can adjust the irradiation angle of light by arbitrarily adjusting the angle of the lighting unit including the LED lamp.
In addition, it is to provide an LED lighting device having good diffusivity of light generated from the LED lamp.
In order to achieve the above object, the LED lighting apparatus according to the embodiments of the present invention includes a heat dissipation unit, an illumination unit and a fixing unit. The heat dissipation part is formed on an upper surface and forms a plate shape having a plurality of heat dissipation fins respectively disposed on both sides of the protrusions extending in front and rear directions and inclined with respect to the upper surface. The lighting unit includes a LED substrate coupled to the bottom of the heat dissipation unit and a plurality of LED lamp units mounted on the bottom of the LED substrate, each having a diffusion lens for diffusing light. The fixing part is fixed to each of the front and rear ends of the heat dissipation unit and a fixing plate having a long hole forming an arc shape around the hinge hole and the hinge hole, and having two fastening holes facing the fixing plate and arranged up and down It includes a bracket, a hinge bolt coupled through the upper fastening hole and the hinge hole and an adjustment bolt coupled through the lower fastening hole and the long hole, the angle can be adjusted in the left and right directions of the fixing plate. .
According to the embodiments of the present invention, the heat dissipation fins in the LED lighting device may have a configuration in which both sides are inclined symmetrically with respect to the protrusion.
According to the embodiments of the present invention, each of the LED lamp unit is a LED lamp mounted on the LED substrate, a housing for accommodating the LED lamp in the conical shape of the upper and lower openings and inserted into and inscribed in the housing The upper part may include a diffuser lens that has an open shape and a lower part has a closed conical shape and diffuses the light of the LED lamp.
In addition, the diffusion lens has a plurality of convex or concave diffusion patterns are formed on the lower surface of the conical shape for the diffusion of light.
In addition, the diffusion lens may include a cylindrical internal lens covering the LED lamp.
According to the embodiments of the present invention, in the LED lighting device, the protrusion is formed to be symmetrically left and right on the upper surface, and a part of the upper end thereof is bent facing each other to form a fastening groove extending in the front and rear directions. It may further include a pair of fastening ribs, and slidingly coupled from the end of the fastening groove is disposed on the upper portion of the heat dissipation portion and may further include a control circuit for driving the LED lamp units.
The LED lighting device according to the embodiments of the present invention configured as described above radiates heat of the LED lamp through a plurality of heat dissipation fins formed on the upper surface of the heat dissipation portion of the plate shape, but the heat dissipation fins are vertical by having a slanted structure. Alternatively, heat dissipation is excellent because the surface area of the heat dissipation fins is increased as compared with the horizontal arrangement.
In addition, by adjusting the angle of the lighting unit in the front and rear directions by adjusting the angle of the fixing unit, it is possible to adjust the range and direction in which the LED lighting device shines light. In addition, since the housing for inducing light and the diffusion lens for diffusing the light for each of the LED lamps are separately provided to diffuse the light from the point of generation of light, the diffusivity is better than that of the integrated diffusion lens.

According to the embodiments of the present invention as described above, the heat dissipation of the LED lamp through a plurality of heat dissipation fins inclined on the upper surface of the heat dissipation portion of the plate shape, the heat dissipation fins are inclined vertically or horizontally by having an inclined structure The heat dissipation effect is improved because the surface area of the heat dissipation fins is increased compared to the case where the heat dissipation fins are disposed.
In addition, by adjusting the angle of the lighting unit in the front and rear direction through the fixing unit, it is possible to adjust the range and direction of shining light even in a state where the LED lighting apparatus is installed and fixed. Therefore, even one LED lighting device can satisfy various light irradiation conditions.
In addition, for each LED lamp, a housing for light induction and a diffusion lens for light diffusion are separately provided, and thus individual configurations are possible. Through this, light is diffused from an initial point of light, and thus light diffusivity is greater than that of an integrated diffusion lens. This is improved.
