Description

Fluorescent lamp with battery spring contact for at least two switching functions.

The present invention relates to a flashlight or flashlight with which at least two switching states for driving a luminous means can be generated simply by rotating a rear part against a front part thereof, and relates to a corresponding method for driving.

Background of the invention and prior art

The known flashlights or flashlights have on the side or on a rear cover part, where batteries can be filled, such as switches or push buttons, through which a respective switching state can be adjusted. A respective switching state is understood to be an activation of, for example, a specific light intensity, a light interval, a light color, a flashing function, a light signal frequency or light patterns. The switching states are detected by an electronics, which then controls at least one light source, such as at least one LED, halogen, or xenon, a laser or other lamp according to the switching state. Switches are expensive if you want them to be durable and sturdy, and they are often expensive to mount and to contact. Often the switches or push-buttons also fail, if, for example, in the low-price segment, they inevitably have to be simple in design.

WO2009 / 079339A2 . US788010062 . US7652216B2 and US8258416B2 For example, discloses a switch as a button for flashlights, which have an electrically conductive dome with laterally projecting feet that can contact a printed circuit board when actuated. One of the side feet is shorter than the others. When the dome is compressed against the printed circuit board, the shorter foot first contacts at a first dome height, then at a second, smaller dome height a central part of the dome also contacts a contact surface on the printed circuit board. In a corresponding design of the cathedral, the dome reversibly folds around like a crackpot frog, so that the shorter foot then lifts off again and gives no contact. A permanent switching function is not possible with these buttons. In addition, a wiring between the button and the electronics is needed, which should sit as close as possible and compact on the light bulbs for cost reasons. A complete Ausfunktion with an inserted battery is not possible without providing an additional switch for disconnecting the battery voltage. As a result, a basic current will still flow in an activated off state of the luminaire without an additional off switch in order to keep the electronics ready for detection for a change of state.

EP1848016A2 discloses a button for flashlights, which consists of two superimposed Knackfroschartigen buttons, which have different stiffness and correspondingly different switching points. In this way, two pressure points can be generated and the flashlight can be driven differently according to a first and a second pressure point. However, a complete decoupling of the battery as off-state is again possible only by a separate switch.

GB1537686 and US3941964 respectively. DE2555137 disclose similar stick-eyed styli as the above-described references with the same drawbacks.

An additional circuit breaker is disadvantageous for several reasons, such as, for example, additional costs and downtime. The second switch or button is another source of leakage. Each additional contact and any additional electrical conduction and bonding required thereby creates an additional source of failure and failure.

DE 20 2010 015 591 U1 discloses a tube lamp with a battery container having at its upper part thereof a lid with threaded connection to fill batteries therein and to be able to contact with a screwing from a certain position in it. The lid has on the inside a first battery contact for contacting an upper battery pole. Turning the lid up and down thus results in a simple switching on / off without the need to switch another contact or a switch in between. At the other, lower end of the battery container is the lamp part. The battery case and the lid make electrical connection of the upper battery pole to the lamp part. The lamp part has internally in the center a contact printed circuit board with a lower second battery contact for contacting the second battery pole. Turning back the lid in the opening direction releases one of the battery contacts from one of the battery terminals, which turns off the lamp. The disadvantage here is that only a single power-on state is possible and in this way only one light intensity can be controlled.

DE 10 2014 112 265 discloses a tube lamp with an adjustable brightness and color of light, which is controlled by a rotation of the tube lamp about its own axis. The Control electronics, however, is expensive and therefore expensive.

Summary of the invention

The object of the invention is to provide a battery-powered penlight or flashlight, which eliminates the disadvantages of the prior art, and with which it is possible to generate at least two switch-on conditions with the least possible effort on components and costs, and the most robust and should be easy to produce.

By the adjusting means 7 between the stop 20 and the lamp part 3 and the contact device 4 can be arranged, but can the battery inlet / outlet opening between the battery container 1 and the lamp part 3 or the battery container 1 and the closure 2 be used. As a result, the adjusting means advantageously have two functions, such as the opening / closing of the battery container 1 and a switch or adjustment function for controlling the tube light. As a result, an additional outward-guided switch is no longer necessary to control the fluorescent lamp. The number of components or switching elements and intervening conductors and contacts and contact junctions is reduced to a minimum, thereby significantly reducing costs and increasing reliability. In the off-state, when the adjustment takes the farthest distance, so that one of the battery terminals is not contacted, a battery load is avoided by a quiescent current, as is the case with a button with active electronics.

One by the adjusting means 7 set force or the corresponding adjustment can be determined and detected by the present invention also at a remote location and the second battery contact K2 by the sensor S1. As at the contact device 4 the first K1 and the second battery contact K2 are arranged and therefore the battery voltage is applied, both the sensor S1 and the electronics 5 and the bulb 6 very simple and with short current and signal paths are interconnected.

As a result, prior art tube lighting mechanisms can be retained and very simply by the contact device according to the invention 4 be improved. This allows a control with two or a plurality of switching states or dimming. In particular, even with a bottle light as in DE 20 2010 015 591 U1 described where only the upper cap, which protrudes from the bottle and is accessible to be used to control the electronics on a lower lamp part in the bottle. In this case, according to the invention, the battery is used as a transmission means from the upper closure lid to the electronics and makes additional transmission means superfluous, which according to the prior art would be either a switching rod or at least a conductor connection.

However, known luminaires have additional switches or buttons or additional sliding contacts for more than one switching function, which are mechanically and electrically complex and impair the robustness.

A preferred embodiment of the contact device 4 in which the sensor S1 is formed by a simple contact spring as the second battery contact K2 and a third contact disposed below K3 on the circuit board is very simple, inexpensive and space-saving in construction. In this case, the third contact K3 is not contacted by the contact spring up to a first spring travel or up to the first adjustment path and then from the second adjustment path and gives one for the electronics 5 very easy to evaluate signal. In the simplest case, a second series resistor can be used as part of the electronics 5 to the light source 6 to be switched, the additional series resistor via an additional power in the bulb 6 feeds. The costs are minimal.

In this case, a digital or analog signal is generated by the sensor S1, which can easily evaluate the electronics to thereby generate a variety of switching states. The sensor and the electronics can be constructed as SMD components very easily and inexpensively. It is thereby made easy dimming with a variety of levels or analog. Particularly advantageous is the possibility of the sensor S1, the electronics 5 and the bulb 6 build compact on a circuit board. The battery voltage is anyway at the contact device 4 at. Here, too, an already existing contact device from the prior art with otherwise the same mechanical housing by the contact device according to the invention 4 simply be replaced as long as the housing is the adjusting means 7 having.
