Abstract
Description
The present invention relates to an LED lighting apparatus, and more particularly, to a high brightness LED lighting apparatus suitable for solving a heat dissipation problem and suitable for factories or workshops with high heights.
In general, a lighting device includes a light source for generating light and illuminates a dark area by illuminating a predetermined range with light generated from the light source. An example of the lighting device is a work lighting device installed on a ceiling or a wall at a factory or a workshop.
Incidentally, incandescent lamps, fluorescent lamps, and three-wavelengths 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.
In addition, in most factories and workshops, lighting devices are installed at high heights, and incandescent lamps, fluorescent lamps, and three-wavelength light sources are relatively low in brightness, so when installed at high heights, the work space on the floor needs lighting. Lighting is not efficient.
In addition, in factories and workshops, there are cases where lighting needs to focus on a narrow area. In general, factories and workshops have high heights, which is difficult to meet when using conventional lighting devices. In addition, heat dissipation is a problem due to heat generated due to high luminance despite low heat generation characteristics.

The power module is accommodated in an accommodating space of the power box and provided to drive the light emitting device package. The support cap is coupled to the upper portion of the power box, and has a circular configuration having a fixed support on the upper surface.
According to the embodiments of the present invention, the heat dissipation portion has a length proportional to the amount of heat generated by the light emitting device package.
According to embodiments of the present invention, the LED lighting device is coupled to the lower portion of the heat dissipation portion to form a spherical inner space and cover the light emitting device package, the transparent to induce the diffusion of light generated in the light emitting device package It may further include a protective lens of the material.
