D.Q.G Design

  

Hi, this is D.Q.G’s home page. D.Q.G is my Chinese name Pinyin initials, or call me George.

from 2010 try to do some original design, up to now, he has produced several works.

Human consciousness and the universe are still the top issues for me.

 

 

below are my works:

 

D.Q.G Tiny AAA is the world smallest AAA flashlight, The latest version is 7th. It's very small, only 57.5 mm long, 12-12.8 mm in diameter. Use single standard AAA size battery (NiMH, alkaline, carbon zinc, Ni-Cd batteries), or a 10440 li-ion battery. Stainless steel only 13.5g and Titanium only 9.4g. Hanging on the key ring, not a bit cumbersome, very harmonious. Suitable for daily lighting, very convenient, easy, a perfect EDC partner.

Output: Low / high, 3 lumens in low, 30 hours; highlight mode 60 lumens, up to 1.5 hours runtime.
Tighten the head on, low mode, loosen the head then quickly tighten again got highlight mode.

After light on, tighten more (or unscrew 1/4 turn), turn off the light. Though this function, the head of light will not drop from the body when hang on the key ring in head loose situation.

Use single standard AAA size battery (NiMH, alkaline, carbon zinc, Ni-Cd batteries), or a 10440 li-ion battery. Made by Stainless steel only 15.5g. Hanging on the key ring, not a bit cumbersome, very harmonious. Suitable for daily lighting, very convenient, easy, a perfect EDC partner.

 

Also there have a extension tube for 2AAA application to be a pen shape flashlight.

Next projects:

Slim AA (1425014500) is on doing.     done.

A Key ring quick-release UV light kit with Tritium location function (still on designing).      quit or other design instead.

 A head light use CR123A/16340/17335/AA/14500 with L SHAPE, also it will be smallest one in the world. (after sampled several years ago, still on designing)             maybe will quit or other design instead.

A thrower flashlight with as small as possible in size up to 3000+ lumens output in high.         still on planning
