Showcase lighting refers to the lighting system used in display cabinets to highlight the appearance and characteristics of displayed items, thereby attracting the attention of the audience. Showcase lighting usually uses LED lights with high brightness and high color temperature, because they can produce bright and clear light, and can present the true color and details of the items. The importance of showcase lighting cannot be ignored because it can improve the attractiveness and display effect of exhibits, thereby increasing sales and audience satisfaction. At the same time, showcase lighting also needs to consider factors such as the size, shape, location of the showcase, and the type and size of the displayed items to ensure the best lighting effect.
Top surface lighting is one of the commonly used showcase lighting methods. It is a lighting method that installs the light source on the top of the showcase so that the light shines on the surface of the displayed items in parallel. This lighting method can evenly illuminate the entire surface of the display item, thereby highlighting the details and characteristics of the display item.
In the early days, the lamp tubes were arranged, and the frosted glass was used underneath to evenly light the light; later, LED panel lights or light strips were used, and the distance between the light source and the glass and the surface treatment of the frosted glass needed to be controlled to ensure uniformity of light.
Advantage of top surface lighting:
Uniform light: the top surface lighting can make the light shine on the surface of the display items in parallel, so that the light can be evenly distributed in the entire display cabinet, and every corner of the display items can get a good lighting effect.
Space-saving: Compared with other lighting solutions, the top surface lighting can make the showcase more compact, because there is no need to install a large number of lamps in the showcase.
Easy to install and maintain: Since the light source is located above the showcase, it is easy to install and maintain, and there is no need to frequently replace the lamps inside the showcase.
Power saving: Using LED lamps as light sources can significantly reduce power consumption and energy costs, and is also beneficial to environmental protection.
Disadvantage of top surface lighting:
Glare: Top surface lighting may produce glare and affect the viewer's sight.
The solution is to adjust the brightness of the light source and make it softer. Another way is to make the frosted glass inside, or heighten the baffle outside the showcase, which will be much better. Another way is to make the glass surface tilt inward, so that the stray light will be in the same direction as the audience's gaze, and it will not enter the audience's sight.
Unable to highlight exhibits: Compared with other lighting solutions, top surface lighting may make exhibits lose their prominence and make it difficult for audiences to concentrate.
Solution: It needs to be improved by combining the interior of the showcase, local lighting, and lights of different colors and temperatures. The interior of the showcase can be made dark, so that the exhibits are shown in the light. Especially exhibits with high reflectivity, such as ceramics.
To sum up, the top surface lighting has its advantages and disadvantages, and it needs to be considered comprehensively according to the characteristics of the displayed items and the size and shape of the showcase in practical application, so as to achieve the best display effect.
