Abstract
Description
The present invention relates to a rod-shaped LED lighting fixture, and more particularly to a rod-shaped LED lighting fixture to improve the brightness of the direction to be prevented by the light emitted from the rod-shaped LED panel to the surroundings.
In recent years, LED lighting, which uses low-power and high-efficiency LED as a light source, replaces fluorescent and incandescent lamps, which are traditional lighting sources, has attracted attention.
LED lighting is not only more energy efficient than fluorescent lamps, but also a long-life and eco-friendly light source. Although the production cost is still more expensive than fluorescent lamps, research on LED lighting is being actively conducted because of these advantages.
Like general lighting, LED lighting can be manufactured in many forms and shapes. Among them, it is possible to produce a bar shape such as a fluorescent lamp of the related art. In the bar-shaped LED lighting, a plurality of LEDs are arranged in a row in a bar-shaped panel.
In the rod-type LED lighting fixtures, a plurality of LEDs are arranged in this manner, but the unit price of LEDs is still higher than that of conventional fluorescent lamps.
In order to solve such a problem, the number of LEDs to be used should be reduced, but if the number of LEDs is reduced, the intensity of the light is weakened so that the user may be dissatisfied. Therefore, in order to reduce the number of LEDs and display luminance satisfactory to the user, it is necessary to develop high-efficiency LED lighting fixtures by concentrating the light to be illuminated.
The present invention has been made to solve the above problems, by concentrating the light in the direction to be illuminated to prevent light leakage around and to reduce the number of LED to provide a rod-shaped LED lighting fixture of the same brightness as before The purpose is to reduce the production cost.
The present invention for achieving the above object, a plurality of LEDs for emitting light; An LED substrate in which the LEDs are arranged in a line; A lens unit provided at the front of the LED to change a traveling path of the light emitted from the LED; It is provided on the side of the lens unit provides a rod-shaped LED lighting luminaire including a reflection shade reflecting the light passing through the lens unit.
It is preferable to vacuum-deposit aluminum or silver on the surface of the reflecting shade.
The inner surface of the lens unit may include an uneven surface, and the uneven surface may have a plurality of sub-curved surfaces in the outward direction of the lens unit.
According to the present invention in the rod-shaped LED lighting fixtures can improve the brightness of the place to be illuminated to reduce the number of LEDs, while maintaining the same brightness as the existing can reduce the manufacturing cost.
The configuration and operation of the embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Referring to Figure 1 and 2 will be described the basic configuration of the rod-shaped LED lighting fixture according to the present invention.
