Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional HID lamps are used for illumination in parking lots or garages, then high luminous power can be achieved, but energy consumption increases and heat dissipation becomes poor
Solution Approach 1:
The patent changes the fundamental illumination technology parameter from HID (high-intensity discharge) to LED (light-emitting diode), which operates at different electrical and thermal parameters. LED lights consume significantly less energy while providing adequate luminous power for parking lots and garages, directly resolving the contradiction between high luminous power and low energy consumption
2Illumination intensity
If traditional HID lamps are used for illumination, then high luminous power is achieved, but lifespan becomes short
Solution Approach 1:
The patent transitions from HID lamp technology to LED technology, fundamentally changing the operational parameters including operating temperature, electrical current, and material composition. LED lights have no filament or gas discharge components that fail, providing a lifespan of 50,000-100,000 hours compared to HID lamps' 10,000-20,000 hours, while maintaining adequate luminous power
3Ease of manufacture
If LED lights with standard light angles (120°, 180°, or 360°) are used, then manufacturing simplicity is maintained, but adaptability for parking lot and garage illumination is insufficient
Solution Approach 1:
The patent divides the illumination function into multiple independent LED light sources arranged in specific geometric configurations (linear, triangular, quadrangular). Each LED module can be manufactured with standard light angles, but their segmented arrangement creates customizable overall beam patterns suitable for different parking lot and garage spaces, resolving the contradiction between manufacturing simplicity and adaptability
Solution Approach 2:
The patent designs a universal LED lighting system where the same basic LED modules can be configured in multiple geometries (linear, triangular, quadrangular) to serve different illumination requirements. This multi-functional design allows a single product line to adapt to various parking lot and garage configurations without requiring specialized manufacturing for each application

AI summary
An LED light includes a housing, a first luminous portion surrounded around the housing, a second luminous portion positioned below the first luminous portion, a heat sink positioned between the first and second luminous portions, a power supply received in the housing and a holder. The holder, the power supply, the first luminous portion and the second luminous portion are electrically connected to form a circuit branch. When the first luminous portion gives out light towards a first direction, the second luminous portion gives out light towards a second direction which is opposite to the first direction. The first and second luminous portions are respectively mounted on the corresponding upper and bottom sides of the heat sink to ensure the LED light simultaneously give out lights towards up and down, meanwhile, the heat sink is positioned between the first and second luminous portions to improve heat dissipation effects and the lifespan of the LED light.
