Museum showcases have a very important role in our lives, so do you understand what are the common lighting methods of museum showcases? The following is a detailed introduction to everyone: 1. The top face light -up. This is the most common lighting method in the early days.
That is, the showcase is shining on the top. All exhibits are at a glance, suitable for small showcases and inspection exhibits details. In the early days, it was arranged with a tube, and the glass was used below to beat the light tube white color.
The fingers were not too high. Later, changed to LED panel lamp or lamp belt. No matter what kind, the distance between the light source and the glass should be controlled, the surface treatment of the froster glass, and the light will be very uniform.
If you can't do it well, it is one by one. Of course, this kind of unhappy place is: ● Top light will generate glare. The solution is the brightness of the coloring light source, and it is softened.
Another way is to make the glass inside, or the gear board outside the showcase is higher, which will be much better. Another way is to tilt the glass surface into tilt, so that the mixed gitamins will be consistent with the eyes of the audience, and it will not enter the audience’s sight. ● The lights are too flat to focus on highlighting exhibits.
Of course, there are also solutions, which can make the interior of the showcase dark. In this way, the exhibits are expressed in the lights. Especially exhibits with high reflectivity, such as ceramics, etc.
2. Top key lighting. This is also a commonly used method, that is, placing halogen lights at the top, a glass in the middle, and through the glass to light up the exhibits.
Glass separates exhibits from lighting to achieve light and heat separation. Different from the first way, this method can achieve key lighting for exhibits. To emphasize the detail, you can also use wide light beam lamps to supplement.
Of course, its disadvantages are also obvious: there is a group of light spots on the glass. Especially the time is long, the glass is ash on the glass, and the light spots are more obvious. In the era of LED, people changed the lamps to small tile digital lamps, and the heat dissipation was much lower! It also changed the glass to a black grille, so it looks much better! However, you must pay attention to the heat of the lamp.
, Excessive of the heat dissipation of the showcase itself, it will cause the accumulation of heat, causing cultural relics damage. No matter what method is changed, it is best to have a layer of partition between the lamps and the exhibits, especially the traditional lamps. There is a partition that can achieve light and heat separation.
On the other hand, if the lamp aging is aging and falls, it can effectively protect the exhibits. Especially the lamps located in the center of the showcase, in case of falling, will cause inestimable losses! 3. In the era of traditional lighting, optical fiber lighting has a large calories, and for precious cultural relics, especially for thermal sensitive exhibits, the lamp itself must be solved itself itself The fever, as well as infrared radiation in light, is more troublesome.
In this case, optical fiber lighting is born in response. The principle is to configure the optical generator at the remote end of the showcase, and then guide the light to the need for the need. This method fully realizes light and heat separation.
Since the light of the light source enters the fiber, it is generally filtered, so the harmful light can be filtered out. Although the light and thermal separation is perfectly solved, there are the following disadvantages: ● High cost, it includes light sources, reflector, color filter, and optical fiber, which is the most cost -effective lighting equipment among all lighting lamps; The fiber is also relatively thick and it is not easy to hide; ● Light flux is small, and it is not suitable for large -scale lighting; ● It is difficult to control the beam angle, especially the small light beam angle. There are many shortcomings, and the advantages are very obvious.
In the early days of traditional lamps, fiber was used more for museum display lighting. But with the popularity of LED lighting, there are fewer and fewer fiber optic fibers. If we have a chance, we will continue to discuss the content of this piece in the future.
We must continue to pay attention to it!.
