Efficient Circuit Design

Updated

“Efficient Circuit Design” is a feature name that appears in TMT datasheet feature lists. TMT gives little detail about what the design consists of. This page records where the name appears, how the patent status is worded, and the efficiency figures TMT publishes, without assessing them.

Where the name appears

Product Wording in datasheet Source
Midi 3 “Efficient Circuit Design (Patent Pending)”; global datasheet: “Energy efficient circuit design (Patent Pending)” Midi 3 datasheet; global Midi 3 datasheet
Midi 4 “Efficient Circuit Design (Patent Pending)” Midi 4 datasheet
Midi Edge “Efficient Circuit Design (Patent Pending)” Midi Edge datasheet
Mini 3 “Efficient Circuit Design (Patent Pending)” Mini 3 datasheet
Mini 2 “High efficiency circuit design” (no patent wording) US Mini 2 datasheet

In each case the entry sits in the same feature list as Cable Hiding Technology and Clean White Technology (Midi Edge datasheet; US Mini 2 datasheet).

Efficiency figures TMT publishes

TMT’s Technology page has a section on efficiency stating up to 178 lm/W at 12 V, and compares this with around 90–120 lm/W for typical market modules; that comparison is TMT’s own (tmtleds.com Technology). The page does not state which module reaches 178 lm/W, and it does not explicitly attribute the figure to the circuit design (tmtleds.com Technology).

Per-product efficacy values differ between TMT sources:

Product Values found Sources
Midi 4 up to 155 lm/W; up to 170 lm/W; up to 174 lm/W Midi 4 datasheet; usa.tmtleds.com listing; usa.tmtleds.com Midi 4
Midi 3 up to 122 lm/W; up to 125 lm/W; 113 lm/W Midi 3 datasheet; tmtleds.com category; usa.tmtleds.com Midi 3

This site does not choose between these values; see TMT regional websites for how differences are handled.

Patent status

TMT describes Efficient Circuit Design as patent pending in the Midi 3, Midi 4, Midi Edge and Mini 3 datasheets (Midi Edge datasheet; Mini 3 datasheet). No patent or application number was found in the sources reviewed, and this site does not state that a patent exists.
