LED Bulb Light Guide Body with Engraved Glyphs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting bulbs, including incandescent and ordinary LED bulbs, face issues of short filament life, complex production processes, high manufacturing costs, and inadequate decorative and lighting effects, which are not effectively addressed by existing LED bulbs with light guide bodies made of materials like acrylic, polycarbonate, or glass.
Innovation Solution
An LED bulb design featuring a light guide body with engraved glyphs on its outer surface, a bulb holder, shell, luminous body, power source, and connector, where the light guide body is a cylinder with spiral or V-shaped glyphs, enhancing light distribution and providing a decorative effect, while simplifying the manufacturing process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light guide body is made of conventional optical materials (acrylic, polycarbonate, epoxy resin, or glass), then the bulb structure is simple and manufacturing is easy, but the light guide effect is unsatisfactory and lighting requirements cannot be met
Solution Approach 1:
The patent uses a composite light guide body made of transparent resin material containing white pigment particles and reflective microparticles. This composite structure combines the transparency of resin with the light scattering properties of white pigment and the reflective properties of microparticles, achieving superior light guide effect while maintaining manufacturing feasibility through injection molding processes.
2Shape
If incandescent bulbs with filament supports are used, then a decorative effect can be achieved, but the filament life is short, production process is complex, and manufacture costs are high
Solution Approach 1:
The patent replaces the traditional incandescent filament mechanical structure with an LED luminous source combined with a light guide body. The LED chip mounted on a circuit board serves as the light source, eliminating the fragile filament while the light guide body with its specific shape and internal structures provides the decorative effect, thus extending service life while maintaining aesthetic appeal.
3Ease of manufacture
If ordinary LED bulbs are used, then the production process can be simplified, but the decorative effect of incandescent bulbs cannot be achieved
Solution Approach 1:
The patent applies local quality by creating specific structural features within the light guide body including protrusions, recesses, and patterned surfaces at particular locations. These localized structural variations scatter and redirect light in specific patterns to create decorative effects, while the overall manufacturing process remains simple through injection molding, thus achieving both aesthetic appeal and manufacturing efficiency.
4Illumination intensity
If a light guide body without special structures is used, then manufacturing is simple, but light distribution is uneven and glowing effect is poor
Solution Approach 1:
The patent segments the light guide body into multiple functional zones with different surface characteristics. The internal structure includes protrusions and recesses that divide the light transmission path into multiple segments, each contributing to uniform light distribution. This segmentation approach achieves even lighting without requiring overly complex external structures, maintaining manufacturing simplicity while improving light distribution uniformity.
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
The engraved light guide body improves light transmission and distribution, extending bulb lifespan, achieving a balanced and soft lighting effect, and reducing manufacturing complexity and costs compared to traditional bulbs.
Implementation Method 1
A bottom of the light guide body is in contact with a luminous body, and depending on total internal reflection, light is transmitted in the light guide body.
Implementation Method 2
the light guide body is engraved with glyphs... the glyphs can further have a decorative effect... light glow and light guide effects may be enhanced by using the glyphs
Implementation Method 3
a top of the light guide body is in a wavy shape or a rhombus shape, and may have a light gathering effect, thereby resolving a problem of glowing at the top of the light guide body, and making the entire bulb body glow evenly and softly.
