Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting lamps lack the ability to simulate the movement of multiple colored light effects and stars/planets in space, leading to monotonous lighting atmospheres that fail to meet evolving user demands for aesthetic and visual stimulation.
Innovation Solution
A space projection lamp comprising a convex lens, uneven reflective lens, reflective motor, and a light source, where the light source is reflected by the uneven lens and passes through the convex lens, creating a layered light effect, and optionally includes additional components like laser and astigmatism sheets or LED and pattern lenses to simulate star and pattern effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional lighting lamps are used, then the lighting function is provided, but the lighting atmosphere is monotonous and cannot simulate space effects
Solution Approach 1:
The patent combines multiple light sources (LED, laser), optical components (convex lens, reflective lens, astigmatism sheet, pattern lenses), and control systems into a single integrated device. This merging enables the lamp to simultaneously provide general lighting, star field projection, pattern projection, and dynamic light effects, thereby achieving versatile lighting atmospheres while managing structural complexity through integration.
Solution Approach 2:
The space projection lamp is designed to perform multiple functions: general illumination, star field simulation, pattern projection, and dynamic light effect creation. By incorporating switchable light sources and multiple optical paths, the device can adapt to different lighting scenarios and aesthetic requirements, making it a universal lighting solution that replaces multiple separate devices.
2Adaptability or versatility
If multiple light sources and optical components are added to simulate space effects, then the lighting atmosphere is enhanced, but light source loss increases
Solution Approach 1:
The patent introduces reflective lenses and condenser lenses as intermediary optical components between the light sources and the projection surfaces. These intermediaries efficiently redirect and focus light, reducing stray light and minimizing energy loss. The reflective lens specifically uses reflection rather than transmission, which reduces absorption losses and improves overall light utilization efficiency.
Solution Approach 2:
The system dynamically adjusts light source parameters (intensity, wavelength, activation state) based on the selected projection mode. The controller regulates the LED and laser light sources to emit light only when needed and at appropriate intensities, reducing unnecessary energy consumption. The optical system also adjusts focus and direction parameters to optimize light delivery and minimize losses.
3Adaptability or versatility
If multiple light sources and optical components are added to simulate space effects, then the lighting atmosphere is enhanced, but production costs increase
Solution Approach 1:
The patent employs cost-effective optical components such as standard convex lenses, reflective lenses, and pattern lenses that can be manufactured using conventional techniques. The LED and laser diodes used are commercially available and relatively inexpensive. By selecting affordable components and standard manufacturing processes, the system achieves complex lighting effects without incurring excessive production costs.
Solution Approach 2:
Instead of using expensive complex mechanical systems to create space effects, the patent uses optical projection of pre-designed patterns (star fields, constellations, planetary patterns) onto surfaces. This copying approach allows realistic space simulations using simple optical projection rather than complex mechanical or electronic systems, significantly reducing manufacturing costs while maintaining visual fidelity.

Data Source
AI summary
A space projection lamp includes the convex lens, an uneven reflective plate, motor, light source, integrated main control and power input. The bottom surface of the uneven reflective plate is fixedly connected with the output shaft of the motor. The convex lens and the light source are respectively arranged on both sides of the uneven reflective plate. The light emitted by the light source passes through the convex lens after being reflected by the uneven reflective plate. When the light source irradiates the uneven reflective plate from the side, the reflection is projected out through the imaging of convex lens, forming a layered light effect. When the motor rotates with uneven reflective plate, it will form a multi-level dream light effect.
