This is also a commonly used method in the early days, that is, to place a halogen lamp on the top with a piece of glass in the middle to illuminate the exhibits through the glass.
The glass separates the exhibits from the lighting, realizing the separation of light and heat.
Different from the top surface lighting type, this method can achieve key lighting for exhibits. To emphasize details, it can also be supplemented with wide-beam lights.

Of course, its shortcomings are also obvious: there are clusters of light spots on the glass. Especially after a long time, dust will accumulate on the glass, the light spots will be more obvious, and the dust accumulation will be clear at a glance.
Entering the LED era, people have changed the lamps into small wattage lamps, and the heat dissipation is much lower! There is also a black grille for the glass, which looks a lot better!

However, we must pay attention to the calorific value of lamps and lanterns. If the calorific value exceeds the heat dissipation of the showcase itself, it will cause heat accumulation and damage cultural relics.
No matter which way it is changed, it is better to have a partition between the lamps and exhibits, especially the traditional lamps.
There are partitions to realize the separation of light and heat. On the other hand, if the lamps are aging and fall, they can effectively protect the exhibits. Especially the lamps located in the center of the showcase, if they fall, it will cause immeasurable losses!
