Abstract

The invention relates to a portable installation, craft or car luminaire which is operated with a battery (mostly Ni-Cd), an extremely flat and powerful fluorescent tube, and special electronic circuitry. The advantages of the Ni-Cd battery system, the high light efficiency and the small current consumption of a fluorescent lamp are combined here for the first time by applying special electronic circuitry. This combination, in conjunction with the flat, oval shape (battery + Dulux fluorescent lamp integrated in the lamp handle) ensures that the luminaire is predestined for craft purposes in general and for vehicle construction in a very particular way. The battery is charged in the already existing charging unit or directly in the vehicle. A novel switch ensures perfect contact-making without sliding contact and offers protection against reversal of polarity. It is possible to adjust the luminaire by means of special contactless wiring. All batteries having the same shape, voltage and polarity can be used. With the aid of suitable adaptors, however, virtually any battery block of the most important electric tool manufacturers can be used as current source. By means of a special supplementary (auxiliary) beam projector, a long-range (long distance) effect is achieved to a considerable degree. The luminaire can also be operated directly from the mains by means of a ballast device.

Description

Das Novum bei dieser Erfindung ist vor allem die Kombination - Leuchtstofflampen und die vorhandenen Ni-Cd Batterien - zu sehen. (Zchg. 1)The novelty of this invention is the combination of fluorescent lamps and the existing Ni-Cd batteries. ( Drawing 1)

Die hohe Lichtausbeute und die geringe Leistungsaufnahme (5 W Leuchtstofflampe ist so hell, wie eine Glühlampe mit 25 W, bzw. 7 W LL wie 40 W GL, oder 9 W LL wie 60 W GL, usw.) eröffnen insbesondere in Verbindung mit Batterie-Stromquellen absolut neue Wege im Bau von Leuchten.The high luminous efficacy and the low power consumption (5 W Fluorescent lamp is as bright as an incandescent lamp with 25 W, or 7 W LL like 40 W GL, or 9 W LL like 60 W GL, etc.) open especially in connection with battery power sources absolutely new ways of building lights.

Das Leistungsaufnahmeverhältnis zwischen Leuchtstofflampen (LL) und Glühlampen (GL) vom Faktor 5-7 wird durch ein system spezifisches Verhalten der Batterie auf Faktor 7 bis 10 zu Gunsten von LL erhöht.The power consumption ratio between fluorescent lamps (LL) and incandescent lamps (GL) by a factor of 5-7 is controlled by a system specific behavior of the battery to factor 7 to 10 Increased in favor of LL.

Aus der Aufstellung ist es ersichtlich, daß es bis jetzt nicht möglich war, eine leistungsstarke Leuchte mit GL zu bauen, ohne daß sie zu teuer, zu groß und zu schwer war. Auch die Wärmeab strahlung bedeutet bei GL Leuchten ein separates Problem. So ist es hier gelungen, eine Profi-Montage-Leuchte zu ent wickeln, die auch mit einer kleinen, vorhandenen Ni-Cd Batterie von z. B. 7,2 V Spannung und lediglich 1,2 Ah Kapazität eine Brenndauer von 2 St. erreicht und dabei eine Lichtstärke er zeugt, die bis jetzt nur von einer 40 W Glühlampe zu bekommen war.From the list it can be seen that it has not so far was possible to build a powerful luminaire with GL without that it was too expensive, too big and too heavy. The heat abs Radiation means a separate problem for GL lights. So it was possible to remove a professional assembly light wrap that also with a small, existing Ni-Cd battery from Z. B. 7.2 V voltage and only 1.2 Ah capacity Burning time of 2 hours reached and a light intensity testifies that so far you can only get a 40 W incandescent lamp was.

Für Anwendungen, die eine stärkere Lichtkonzentration verlangen, wird die Leuchte mit einem Zusatzscheinwerfer, der einen Weitstrahlereffekt hat, versehen.For applications that require a higher light concentration, is the lamp with an additional headlight that one Has wide beam effect provided.

Claims

1. Universal professional fluorescent tube mounting light, operable with the usual existing batteries from the power tool area, characterized by the following features:

a) the combination fluorescent lamp and Ni-Cd battery, it enables cost-effectiveness of completely new dimensions; With the same luminous efficacy, a power consumption which is at least 7 times lower than that of incandescent lamps and five times the service life is achieved;
b) the combination of DULUX compact fluorescent lamp with an oval Ni-Cd battery gives the lamp an extremely flat shape, which is of great importance for the assembly and for illuminating cavities such. B. is clearly ideall under the fender of the vehicle; ( Drawing 1)
c) the lamp is operated with an electronic high-frequency operating system, which significantly increases the system light yield;
d) the lamp is equipped with commercially available 220 V fluorescent lamps and can also be operated directly from the mains by means of an adapter;
e) an additional headlight ensures a large concentration of light through a special mirror technology;
f) the handle of the lamp is designed so that virtually any battery used by the leading power tool manufacturers can be used as a power source by means of a receptacle; ( Drawing 1)
g) a modular system also allows the production of much more powerful lights;
h) minimum luminous flux 250 lm, (25 W incandescent lamp reaches luminous flux of 230 lm).
