Stage Light Decorative Effect via Independent Side Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional stage lights lack decorative effect when the main light source is off, appearing monotonous and failing to attract audience attention.
Innovation Solution
Incorporating an independent effect light source and light-transmitting plate within the stage light, allowing for additional visual effects without obstructing the main light path, with the effect light source capable of being controlled separately to illuminate the light-transmitting plate even when the main light is off, enhancing the decorative effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If an effect light source and light-transmitting plate are added to provide additional visual effects, then the decorative effect and visual appeal of the stage light is improved, but the device complexity increases
Solution Approach 1:
The stage light is divided into two independent lighting systems: a main light source for primary illumination and an effect light source for decorative effects. Each system can be controlled independently, allowing the effect light source to illuminate the light-transmitting plate without affecting the main light path when needed.
Solution Approach 2:
The light-transmitting plate is positioned at the light outlet of the lampshade, utilizing the spatial dimension at the exit of the main light path. This allows the effect light source to create visual effects in a different spatial dimension without blocking or altering the main light path.
2Illumination intensity
If the light-transmitting plate is made thicker to improve light utilization and brightness, then the brightness of the light-transmitting plate is improved, but the main light path may be blocked causing dark areas in the projected light spot
Solution Approach 1:
The light-transmitting plate has selective optical properties: its first surface and second surface are frosted to diffuse and reflect light for brightness enhancement, while its thickness (0.5mm to 3mm) is optimized to be sufficient for light utilization but thin enough to allow main light path transmission without causing obvious dark areas.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution increases the visual appeal of the stage light itself by providing additional lighting effects, making it more attractive and maintaining the main light's effect without blocking or altering the light path, while ensuring sufficient brightness and flexibility through independent control and multiple color options.
Implementation Method 1
the light emitted by the effect light source is refracted and reflected after entering into the light-transmitting plate through the first side
Implementation Method 2
the light emitted by the effect light source is refracted and reflected after entering into the light-transmitting plate through the first side
Implementation Method 3
At least one of the first surface and the second surface is frosted. By the surface frosting process, the light emitted by the effect light source is refracted and reflected

AI summary
A stage light with an additional visual effect includes a main light source and a lampshade, the main light source being located at a bottom of the lampshade. The stage light further includes at least one effect light source and at least one light-transmitting plate located at a light outlet of the lampshade. The effect light source and the main light source are controlled independently of each other. The light-transmitting plate has a first surface and a second surface, and a first side and a second side connecting to the first surface and the second surface, respectively. At least part of the light emitted by the effect light source enters from the first side and exits from the second side. The light emitting by the effect light source exits from the second side, so that the second side is illuminated, which decorates the stage light itself.
