A problem with this lamp is that the filament location is not controlled.

Part of the reason for that is there is no reference surface on the base to support good filament location.

I have included on this page what most people would consider a flashlight, but also any light that uses the No. Also some fixed battery powered lights like used on barricades or in purses, &etc. And some closley related patents like anti reflection coatings or earlier lights.

Not on the page are patents related to Flashlights as used on cameras.

The key components of a portable light source are: Source of power, A way to start and stop the light source, A way to convert the power into light , A way to control the light.

For a flashlight these would be: Dry Cell battery, switch (aka circuit closer), lamp with a filament, reflector and/or lens.
