LED Lamp Color Coding for Lumen and Beam Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Landscape lighting systems lack the ability to easily and accurately identify lumen values and beam spreads of LED lamps, requiring designers and installers to physically remove lamps to read fine print markings, which is time-consuming and confusing, especially when multiple lamps of the same color are used.
Innovation Solution
Assigning unique colors to LED lamps based on lumen levels and beam spreads, with visible markings on the optic of the lamp indicating beam angles and lumen ranges, allowing for quick identification without removing the lamp from the fixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If micro-printed markings are used to identify lumen and beam spread, then information can be provided on the lamp, but the markings are difficult to read and identify quickly
Solution Approach 1:
The patent applies color coding to the lamp body or housing to indicate different lumen levels and beam spread angles. Each color represents a specific combination of lumen output and beam angle, allowing installers to quickly identify lamp specifications at a glance without reading fine print. This visual color-coding system transforms abstract technical specifications into intuitive visual information.
Solution Approach 2:
The patent moves the identification information from a two-dimensional micro-printed surface (requiring close inspection) to a three-dimensional visual feature (color) that can be perceived from a distance. By encoding specifications in the color dimension of the lamp housing, the system enables rapid identification without requiring the installer to physically接近 or closely examine the lamp.
2Ease of manufacture
If all lamps are the same color, then manufacturing is simplified, but installers cannot quickly differentiate between different lumen and beam spread specifications
Solution Approach 1:
The patent applies different colors to specific local regions of the lamp assembly, such as the housing, trim, or accent pieces, while maintaining the same LED chip color temperature. This allows the lamp to retain manufacturing simplicity (same LED components) while adding visual differentiation through colored housing or trim elements that indicate lumen and beam spread specifications.
Solution Approach 2:
The patent uses color variations in the lamp housing, trim, or accent pieces to encode different lumen and beam spread specifications. This allows installers to quickly differentiate between lamp types during installation without complicating the core LED manufacturing process, as the color coding is applied to external housing elements rather than the LED chips themselves.
3Loss of information
If lamp specifications are not clearly visible, then designers must remove lamps to read markings, but this increases installation time and complexity
Solution Approach 1:
The patent uses prominently visible color coding on the lamp housing or trim that can be observed without removing the lamp from the fixture. Different colors indicate different lumen levels and beam spread angles, allowing designers to verify specifications in-situ and make quick replacement decisions without the time-consuming process of removing lamps to read micro-printed markings.

AI summary
A landscape lighting system includes a first LED lamp including a first lamp body and an optic having at least one LED for generating light, and a second LED lamp including a second lamp body and an optic having at least one LED for generating light. The first lamp body has a first color for indicating a first lumen level for the light generated by the first LED lamp, and the second lamp body has a second color that is different than the first color for indicating a second lumen level for the light generated by the second LED lamp. The second lumen level is different than the first lumen level. The optics of the first and second LED lamps have transparent covers with beam angle spread indicators provided on the respective transparent covers. At least one of the optics has a color temperature indicator on a transparent cover.
