Today, showcases have become an important form of display in museums, art galleries and various exhibitions. In these showcases, lighting is one of the essential elements. Appropriate lighting schemes can better highlight the characteristics of the exhibits, modify the environment, and prolong the life of the exhibits and protect their integrity.
Traditional showcase lighting often uses metal halide lamps and other heat-generating light sources, which can easily affect the safety and viewing effect of exhibits. In order to solve this problem, scientific and technological personnel have developed many new lighting methods for showcases, the most representative of which is fiber optic lighting.
Fiber optic lighting is a display cabinet lighting method that realizes the separation of light and heat. It uses the principle of optical fiber light guide to transmit the light source from the far end of the display cabinet to the position that needs to be illuminated, thus avoiding the defects of traditional lighting methods. Since the light generated by the light source will be filtered before entering the optical fiber, the harmful light will be filtered out, and only the useful visible light will reach the exhibits. Therefore, the optical fiber lighting can better protect the exhibits, slow down their aging speed, and reduce the impact on the environment. pollution.
Compared with traditional lighting methods, fiber optic lighting has the following advantages:
Photothermal separation. Since the light source is completely isolated from the exhibits, there will be no excess heat and infrared radiation, thus ensuring the safety and protection of the exhibits.
flexibility. Fiber optic lighting can achieve more refined lighting requirements by flexibly adjusting the position and direction of the light source. At the same time, because the optical fiber is soft and easy to bend, more diverse and creative lighting designs can be realized.
Energy saving and environmental protection. The LED light source used in fiber optic lighting has low power consumption, long life, and no harmful substances such as mercury and ultraviolet rays, so it also plays a positive role in environmental protection and energy saving.
Good color rendering. The LED light source used in fiber optic lighting has a high color rendering index, which can restore more real and natural colors of exhibits and enhance viewing experience.
While fiber optic lighting has many advantages, there are some limitations:
Higher cost, including light source, reflector, color filter and optical fiber, etc., is the most expensive lighting device among all lighting fixtures;
The overall shape is larger, and the optical fiber is also thicker, so it is not easy to hide;
The luminous flux is small, not suitable for large-area lighting;
It is difficult to control the beam angle, especially for small beam angles, but since the light from the fiber optic head is not harmful, it can be very close to the exhibits.
Some people tend to confuse fiber optic lighting with neon lights, but these are two different lighting methods, and they have the following differences:
The working principle is different: fiber optic lighting uses the principle of fiber optic light guide to transmit the light source to the position that needs to be illuminated, while neon lights emit light by placing gas in the glass tube and emitting fluorescence under the excitation of a high-frequency electric field.
Bulbs are constructed differently: LED light sources in fiber optic lighting are usually tiny chips, while bulbs in neon lights consist of a glass tube, electrodes, and gas.
The energy efficiency ratio is different: fiber optic lighting uses LED light source, which has relatively high energy efficiency, which can save energy and reduce carbon emissions; while the energy efficiency of neon lights is relatively low, and relatively speaking, it consumes more energy for the environment.
The service life is different: the LED light source of fiber optic lighting has a long service life and basically does not need to be replaced; while the bulb of a neon light has a short service life and needs to be replaced frequently.
Different application scenarios: fiber optic lighting is generally used in refined occasions such as showcase lighting and decorative lighting, while neon lights are more used for large-area lighting needs such as advertising signs and landscape lighting.
Therefore, when choosing the lighting method of the showcase, it is necessary to comprehensively consider various factors and choose the most suitable lighting scheme according to the actual situation.
