Replaceable Decorative Covers for Fully Illuminated Light Strings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light strings suffer from decorative covers that are not fully illuminated due to being located on the non-luminous side of light emitting units, affecting the decorative effect.
Innovation Solution
The decorative covers are detachably mounted on lamp shades, ensuring they are positioned on luminous sides of light emitting units, with a clamping mechanism for easy assembly and disassembly, and a lamp holder system for electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If decorative covers are detachably connected to lamp holders, then rapid replacement of decorative covers is enabled, but some decorative covers are located on non-luminous sides and not fully illuminated
Solution Approach 1:
The patent divides the light string structure into separate functional components: lamp holders for electrical connection, lamp shades for light direction control, and decorative covers for aesthetic purposes. This segmentation allows each component to be optimized independently - the lamp shade can be positioned to ensure full illumination of the decorative cover while maintaining easy detachability.
Solution Approach 2:
The lamp shade acts as an intermediary component between the light emitting unit and the decorative cover. It is positioned on the luminous side to receive and redirect light, ensuring the decorative cover is fully illuminated. The lamp shade's clamping structure provides the detachable connection while maintaining proper light distribution.
2Device complexity
If decorative covers are directly connected to lamp holders, then assembly is simplified, but decorative effect is reduced due to poor illumination
Solution Approach 1:
The patent introduces a lamp shade as a separate component between the lamp holder and decorative cover. This segmentation adds only one simple clamping structure while solving the illumination problem by positioning the light-emitting portion on the luminous side, ensuring the decorative cover is fully lit without significantly increasing overall complexity.
Solution Approach 2:
The lamp shade serves multiple functions: it provides structural support for the detachable connection, controls light direction to illuminate the decorative cover, and maintains the spacing needed for proper light distribution. This multi-functionality achieves good illumination without requiring multiple separate components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the decorative effect by ensuring more parts of the decorative covers are illuminated, improving applicability and diversity for various scenes.
Implementation Method 1
a light emitting unit, connected to the lamp base, the light emitting unit being configured to emit light when powered on
Implementation Method 2
a clamping portion is provided on an outer side wall of each of the lamp shades in a protruding manner, and a clamping slot is formed in an inner wall of the corresponding accommodating cavity

AI summary
Disclosed is a light string with replaceable decorative covers, which relates to the technical field of light strings. The decorative light string includes multiple decorative lights, and each of the decorative lights includes a lamp base, a light emitting unit, a lamp shade, a lamp holder, and the decorative cover, where the decorative cover can be detachably mounted on the lamp shade, which allows the decorative cover to be located on a luminous side of the light emitting unit and thus makes it fully illuminated when the light emitting unit emits light. The light string has the advantages of being simple in structure, convenient and fast to disassemble and assemble, and good in decorative effect.
