Solution Overview
Problem
Conventional downlight devices lack flexibility and advanced functionality, limiting their ability to provide variable and efficient light effects and settings, while also not addressing issues like glare and safety concerns effectively.
Innovation Solution
A lighting apparatus featuring two light sources with adjustable emission directions, a second light housing with a surrounding lateral wall that can be tilted or positioned at specific angles, and a driver container with modified IDEAL connectors for enhanced flexibility and safety features such as waterproofing and fire prevention, along with optional features like image projection and integrated modules for additional functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional downlight devices are used, then installation is simple, but flexibility and advanced functionality are limited
Solution Approach 1:
The lighting apparatus is divided into multiple independent light sources (first light source in first light housing, second light source in second light housing) that can be separately controlled and positioned. This segmentation allows each module to perform specific functions while maintaining overall system flexibility and adaptability.
Solution Approach 2:
The second light housing is designed with adjustable positioning capability, allowing it to be tilted at angles between 60-150 degrees relative to the first light direction. This dynamic adjustment enables variable light effects and glare reduction while maintaining installation flexibility.
2Object-affected harmful factors
If light is emitted directly without diffusion, then illumination intensity is high, but glare problems occur
Solution Approach 1:
A diffusing structure is introduced as an intermediary element between the light source and the environment. This diffuser scatters the direct light into diffused light, reducing glare while maintaining sufficient illumination intensity for the application.
3Reliability
If standard connectors are used, then electrical connection is simple, but safety concerns like waterproofing and fire prevention are not addressed
Solution Approach 1:
The connector structure integrates multiple functional properties into a single component: IDEAL connector geometry for electrical connection, waterproof coating or material for moisture protection, and fire-retardant materials for thermal safety. This composite approach enhances reliability without significantly increasing structural complexity.
4Adaptability or versatility
If single light source is used, then device structure is simple, but variable light effects cannot be achieved
Solution Approach 1:
The lighting apparatus incorporates multiple light sources (first and second light sources) that can be independently controlled to achieve various lighting functions: primary illumination, accent lighting, glare reduction, and adjustable color temperature. This multi-functionality allows a single device to replace multiple separate lighting fixtures.

Implementation Method 1
a first light source, a first light housing, the first light housing being for disposing the first light source to emit a first light from a first direction
Implementation Method 2
a second light source and a second light housing, the second light housing being for disposing the second light source to emit a second light from a surrounding lateral wall of the second light housing
Data Source
AI summary
A lighting apparatus includes a first light source, a first light housing, a second light source and a second light housing. The first light housing is for disposing the first light source to emit a first light from a first direction via a first light opening. The second light housing is for disposing the second light source to emit a second light from a surrounding lateral wall of the second light housing. An angle between the first light direction and a radial direction of the surrounding lateral wall is between 60 degrees to 150 degrees. An inner wall of the second housing is surrounding and fixed to a neck portion of the first light housing.
