LED Light With Built-In Projection And Night Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current night lights lack a built-in projection function and continuous power source, with most projection lights powered by batteries and incandescent bulbs that cannot be left on continuously due to short battery life, and conventional projection lights lack features like continuous switch positions, built-in night lights, power saving circuits, adjustable focus, and swivel mechanisms for long-distance projection.
Innovation Solution
An LED light with a built-in projection and night light that can be powered by an outlet or battery, featuring a continuous switch, power saving circuit, adjustable focus, swivel, spin, and rotate mechanisms, allowing for long-distance projection and extended use with a combination of switch means, sensors, and motor-driven image rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If battery-powered projection light is used, then portability is improved, but operation duration and continuous operation capability deteriorate
Solution Approach 1:
The light device is designed to support multiple power sources (battery and outlet power) and multiple functions (projection and night light) within a single unit, allowing it to adapt to different usage scenarios and eliminate the trade-off between portability and continuous operation
2Illumination intensity
If conventional bulb light source is used, then brightness is improved, but energy consumption and power requirements worsen
Solution Approach 1:
The patent transitions from conventional bulb light sources to LED light sources, fundamentally changing the operational parameters of the lighting system to achieve high brightness with low energy consumption, enabling continuous operation and eliminating the need for frequent battery replacements
3Adaptability or versatility
If projection function is added to night light, then functionality is improved, but device complexity worsens
Solution Approach 1:
The patent combines the projection light function and night light function into a single integrated device with shared optical components and power source, eliminating the need for separate devices and reducing overall system complexity while maintaining full functionality

Data Source
AI summary
An LED light has a built-in projection light and a night light to offer at least two functions for people in a dark environment. The projection light can project an image from any type of display-unit irrespective of geometric shape or image source or type, including display of digital data, wireless digital data, an LCD or TFT screen display, or any other display, enabling images of enlarged size to be projected onto a preferred surface, making it easier for people to see the image. The built-in night light helps people see things in a dark environment.
