Headlamps

Construction and mining.

Object of the invention

Increase Candles, Lumen generated with the minimum energy consumption, while minimizing the capacity of glare.

Prior art

The utility model 0142488_u is possibly the oldest patent of a headlamp for frontal use. This first It had a filament bulb to generate light. Not long ago LED headlamps have appeared, which are the future of lighting but for now this is not possible because of its poor color quality

Also recently there are manual flashlights Laptops with fluorescent tubes. Many years ago this was possible since the appearance of the electronic ballast or ballast electronic and DC / AC and DC / DC converters, and a power of the fluorescent tubes of 18 / 20wL18W / 10, which made them impossible for frontals given its size. It has had to wait many years for the appearance of small fluorescent tubes of way they were useful for use in flashlights and flashlights front. A few years ago PRILUX and other brands released the F4T5 / D and This tube serves and is used in portable flashlights, but it does not work as frontal, because it is too big. OSRAM took out the DULUX S / E 2G7 and although it is viable, it is still a bit large as a source front light emitter and OSRAM only has it as a handheld flashlight at four batteries 1.5 v that is 6 v.

Explanation of the invention.

The invention consists in using as a source of light emission in the headlamp, a fluorescent micro-tube powered by a electronic ballast, with a margin of operation 6-12 v. For the rest, it basically has the rest elements of a headlamp: reflector with its base support For protection and support, the battery holder, switch, cables...

Although the fluorescent tubes have a great size compared to LEDs this in itself is not a inconvenient but quite the opposite. It is an advantage because at emitting the same light from a larger surface does not produce as much glare as LEDs do, especially the latest models of a single LED of 1 W and next of 3 W. And also the chromatic variety of fluorescent tubes is at the moment greater than that of LEDs which makes them better for the health of The eyes lighting with fluorescent tube.

It has the disadvantage that all electronic reactances, for the ignition of the tube they need a Strong medium-high voltage. OSRAM has a Induction tubeless filament prototype that does not have this problem, the downside is that at the moment it does not have it in micro-tube format

Brief explanation of the drawings

Figure 1 is a 1 W tube made in China or unknown and has dimensions of 8 mm in diameter of the tube exterior and a length of 50 mm. It has no nomenclature standardized The not exact form is very approximate.

Figure 2 is a 3W tube of Chinese manufacture or unknown and has dimensions of 11 mm diameter tube exterior and a length of 50 + 50 mm. It has no nomenclature standardized The not exact form is very approximate.

The rest of the figures are from a 7 w tube with a very capricious way to occupy little room and has the tube dimensions of 6 mm outside diameter and a maximum length 34 mm, 34 mm wide, 14 mm high and can enter a circumference of 43 mm in diameter. In the format from which it marketed comes with its reflector and a protective glass that It helps blur the light. It has no standardized nomenclature. The Not exact form, it is very approximate.

An embodiment

The most powerful is with the 7 w tube a small electronic ballast or electronic ballast and a battery holder for eight batteries and has a connector for the external connection to 12 v, and a circuit for possible battery charging, so that in any time you can load them and even the simultaneous operation of the tube and the battery charge. Have a protective glass that helps blur light and has basically the remaining elements of a headlamp: reflector with its base support for protection and support, the battery holder, switch, cables ...

An embodiment

The most powerful is with the 3 w tube with a electronic ballast and a battery holder for eight batteries and has of a connector for the external connection to 12 v, and a circuit for the possible charging of batteries, so that at any time you can load them and even run Simultaneous tube and battery charge. Has basically the remaining elements of a headlamp: reflector with its base support for protection and support, the battery holder, switch, cables ...

An embodiment

The most powerful is with three 1 w tubes in parallel and an electronic ballast and a battery holder for eight batteries and has a connector for the external connection to 12 v, and a circuit for the possible charging of batteries, so that in any time you can load them and even the simultaneous operation of the tube and the battery charge. Have basically the remaining elements of a headlamp: reflector with its base support for protection and support, the battery holder, switch, cables ...
