Sloping LED Holder Cup Cover for Brightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED display screens installed at high outdoor locations require viewers to tilt their heads upward, leading to reduced brightness perception due to the alignment of the light-emitting surface and pin welding plane, which are either parallel or perpendicular, resulting in obscured light emission.
Innovation Solution
The LED holder features a sloping cup cover with differently heighted lateral surfaces and exposed metal pins, allowing the LED chip's light to be directed downward and facilitating easier installation and stability, thereby enhancing brightness perception and installation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the LED display screen is installed at a high outdoor location, then the display screen can be installed in appropriate locations, but the perceived brightness decreases because viewers must tilt their heads upward and the light emission is obscured
Solution Approach 1:
The patent inverts the traditional horizontal or perpendicular orientation of the LED light-emitting surface by introducing a sloping cup cover structure. The light-emitting surface is tilted at an angle (e.g., 15-45 degrees) relative to the horizontal plane, causing light to emit downward toward viewers rather than upward or horizontally. This inversion of the emission direction resolves the contradiction by maintaining adaptability for high-location installation while improving perceived brightness for upward-viewing audiences.
2Device complexity
If the light-emitting surface is disposed horizontally or perpendicular to the pin welding plane, then the structure is simple, but the light emission is obscured when viewed from an elevation angle
Solution Approach 1:
The patent applies asymmetry by creating an uneven, sloping cup cover structure where one lateral surface is higher than the other. This asymmetric geometry tilts the LED chip and light-emitting surface at a specific angle, optimizing light emission direction toward ground-level viewers. The asymmetric design balances structural simplicity with improved brightness perception by directing light along a downward trajectory rather than maintaining symmetric horizontal or perpendicular orientations.
3Illumination intensity
If the cup cover bottom is made sloping, then the light propagation direction is optimized, but the installation and fixation complexity increases
Solution Approach 1:
The patent resolves the installation complexity issue by extending metal pins from lateral surfaces of the sloping cup cover rather than from the bottom. This dimensional change in pin placement allows the sloping structure to maintain optimized light propagation while providing accessible, standardized installation interfaces. The pins protruding from lateral surfaces enable straightforward fixation to mounting substrates without requiring complex bottom-access procedures.
4Productivity
If metal pins are disposed on lateral surfaces of different heights, then the installation speed increases, but the structural complexity increases
Solution Approach 1:
The patent applies local quality by positioning metal pins at different heights on different lateral surfaces of the cup cover. This localized variation in pin height optimizes installation speed by allowing simultaneous or sequential fixation at multiple points without requiring complex adjustment mechanisms. The differentiated pin heights correspond to the sloping geometry, enabling quick alignment and secure mounting while maintaining overall structural simplicity through the integration of pins into the cup cover's lateral surfaces.

AI summary
Provided are an LED holder, an LED device and an LED display screen. The LED holder includes a metal frame and a cup cover wrapping the metal frame. The cup cover includes a reflective cup. The cup cover has a first lateral surface and a second lateral surface disposed opposite to each other. A height of the first lateral surface is greater than a height of the second lateral surface. The metal frame includes metal pins exposed outside the cup cover and disposed on the first lateral surface and/or the second lateral surface. The bottom of the cup cover is of a sloping structure, so that the light emitted by an LED chip in the reflective cup propagates along a specified direction.
