Analysis of the difference between fiber optic lighting and LED lighting

Nowadays, under the advocacy of the concept of green lighting, various lighting technologies are constantly emerging. Fiber-optic lighting and LED lighting as emerging lighting technologies have always been at the forefront of the era of green lighting.

First, fiber optic lighting

Fiber optic lighting is an emerging form of lighting in recent years. Due to the unique physical properties of the fiber itself, fiber optic lighting is used in interior decorative lighting, local effect lighting, billboard lighting, guided lighting in public areas of buildings, indoor and outdoor underwater lighting, and building contours and facades. Among the lighting, and good lighting effects have been achieved. The fiber optic illumination system consists of a light source, a mirror, a color filter, and an optical fiber. When the light source passes through the mirror, a bundle of approximately parallel light is formed. The light beam is turned into colored light due to the action of the color filter. When the beam enters the fiber, the colored light is sent to the intended location along the path of the fiber. The light source is generally strong due to the loss of light on the way. Commonly used light sources are around 150~250W. And in order to obtain an approximately parallel beam, the point of illumination should be as small as possible, similar to a point source. Mirrors are an important factor in the ability to obtain approximately parallel beams. Therefore, aspherical mirrors are generally used. A color filter is a part that changes the color of a beam. According to the need, the corresponding color light source is obtained by changing the filters of different colors. Optical fiber is the main body in a fiber-optic lighting system. The function of the fiber is to transmit or transmit light to a predetermined place. The optical fiber is divided into two types: end light emission and body light emission. The former is that after the beam is transmitted to the end point, it is illuminated by the tail light, and the latter itself is the illuminator, forming a flexible beam. For fiber optic materials, it must be in the visible range, the loss of light energy should be minimized to ensure the quality of the illumination. However, it is practically impossible to have no loss, so the optical fiber transmission distance is about 30 m.

Features of fiber optic lighting:

1. A single light source can have a plurality of light-emitting points having the same light-emitting characteristics.

2. The light source is easy to replace and easy to repair.
