Licht, abstrahlt. Derartige Leuchtmittel sind jedoch teuer, aufwendig und umweltbelastend in der Herstellung und haben eine nicht zufriedenstellende kurze Lebensdauer. Ferner weisen sie einen schlechten Wirkungsgrad auf.Conventional lamps have a base and one arranged on it Glass bulb, in which, for example, a tungsten wire in an inert gas atmosphere is energized and electromagnetic due to appropriate thermal effects Waves in the visible spectral range, i.e. Light that emits. such However, lamps are expensive, complex and polluting to manufacture and have an unsatisfactory short lifespan.

Femer sind Leuchtstoffe erforderlich, da die direkt von der Gasentladung erzeugten elektromagnetischen Wellen in der Regel nicht im sichtbaren Spektralbereich sind. Zusätzlich benötigen derartige Lampen einen Glaskolben, in dem die Gasentladung abläuft, sowie eine in den Sockeln enthaltene Steuerelektronik, was einen entsprechend großen Bauraum erfordert. Ferner benötigt die Lampe eine lange Zeit, bis die Gasentladung eine volle Nennlichtstärke erreicht. Up to now, gas discharge lamps with corresponding have been an improvement Pedestals suggested. However, these require a high starting voltage and a corresponding control signal for maintaining the light-generating gas discharge. Fluorescent materials are also required because they are directly from the gas discharge generated electromagnetic waves usually not in the visible Are spectral range. In addition, such lamps require a glass bulb, in which the gas discharge takes place, as well as control electronics contained in the bases, which requires a correspondingly large amount of space. Furthermore, the Lamp for a long time until the gas discharge reaches a full nominal light intensity.

Es ist Aufgabe der vorliegenden Erfindung, ein verbessertes Leuchtmittel der obengenannten Art insbesondere für eine verbesserte Signalleuchte zur Verfügung zu stellen, welche die obengenannten Nachteile beseitigen. It is an object of the present invention to provide an improved lamp above type in particular for an improved signal light available to provide, which eliminate the disadvantages mentioned above.
Diese Aufgabe wird durch ein Leuchtmittel der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst.This task is performed by a lamp from the above. Kind with those characterized in claim 1 Features resolved.
Dazu ist es bei einem Leuchtmittel der o.g. Art erfindungsgemäß vorgesehen, daß der Leuchtkörper eine Leiterplatte mit daran angeordneten Leuchtdioden umfaßt, wobei für eine Rundumleuchtwirkung die Leuchtdioden stehend und liegend an der Leiterplatte angeordnet sind, derart, dass diese bezüglich der Leiterplatte in wenigstens vier verschiedene Richtungen elektromagnetische Wellen im sichtbaren Spektralbereich abstrahlen, wobei die Abstrahlrichtungen der Leuchtdioden senkrecht zueinanderstehen und in einer Ebene oder in verschiedenen Ebenen liegen und wobei für jede Abstrahlrichtung eine oder wenigstens zwei Leuchtdioden vorgesehen sind.For this, it is a lamp of the above. Provided according to the invention, that the luminous body is a printed circuit board with light-emitting diodes arranged thereon comprises, for an all-round lighting effect, the LEDs standing and lying are arranged on the circuit board in such a way that they are in relation to the circuit board electromagnetic waves in at least four different directions emit visible spectral range, the direction of radiation of the light emitting diodes stand perpendicular to each other and in one plane or in different Layers lie and one or at least two for each radiation direction LEDs are provided.
Eine Rundumleuchtwirkung wird dadurch erzielt, daß mehrere Leuchtdioden derart an der Leiterplatte angeordnet sind, daß diese bezüglich der Leiterplatte in wenigstens vier verschiedene Richtungen elektromagnetische Wellen im sichtbaren Spektralbereich abstrahlen. Dies simuliert in besonders vorteilhafter Weise ein Leuchtmittel mit rundum abstrahlendem Glaskolben.An all-round lighting effect is achieved in that several light emitting diodes are arranged on the circuit board so that they are in relation to the circuit board at least four different directions of electromagnetic waves in the visible Radiate spectral range. This simulates in a particularly advantageous manner a lamp with an all-round radiating glass bulb.
Dies hat den Vorteil, daß herkömmliche Leuchtmittel mit beispielsweise Glaskolben als Leuchtkörper durch Leuchtmittel mit wesentlich höherer Lebensdauer, niedrigeren Herstellungskosten bei hohen Stückzahlen, besserem Wirkungsgrad, d.h. größer Leuchtkraft bei geringerem Energieverbrauch, sowie ggf. besserer Signalwirkung ersetzt werden können.This has the advantage that conventional lamps with, for example, glass bulbs as a luminous element by means of lamps with a significantly longer service life, lower manufacturing costs with large quantities, better efficiency, i.e. greater luminosity with lower energy consumption, and possibly better Signal effect can be replaced.

Eine universelle Anwendungsmöglichkeit des Leuchtmittels bei unterschiedlichsten Geräten, welche bisher Glaskolbenleuchtmittel verwenden, ohne Umbau des Gerätes selbst erzielt man dadurch, daß der Sockel ein Standardsockel, insbesondere für eine Glühbirnenfassung, beispielsweise vom Typ BA9s, BA15d, E14, E27, ist.

Ein Einsatz in Signalleuchten mit entsprechenden signalartigen Lichtzeichen, wie beispielsweise Blinken, realisiert man dadurch auf einfache Weise, daß die Leiterplatte einen elektronischen Schaltkreis, insbesondere wenigstens einen integrierten Schaltkreis und/oder wenigstens ein SMD-Bauteil, zum Ansteuern der Leuchtdioden aufweist. Dies vereinfacht zusätzlich in vorteilhafter Weise herkömmliche Signalleuchten, da diese selbst keine Steuerelektronik oder nur eine sehr triviale, wie Ein-/Ausschalter, benötigen, wodurch diese kostengünstig herstellbar sind.Use in signal lights with corresponding signal-like light signals, such as for example, blinking, is realized in a simple way that the circuit board an electronic circuit, in particular at least one integrated Circuit and / or at least one SMD component to control the Has LEDs. This also advantageously simplifies conventional methods Signal lights, since these themselves have no control electronics or only one very trivial, such as on / off switches, which makes them inexpensive to manufacture are.
Zweckmäßigerweise ist die Leuchtdiode, je nach Einsatzzweck und Einsatzumgebung, eine weiße bzw. farblose und/oder farbige LED.The light-emitting diode is expediently, depending on the intended use and environment a white or colorless and / or colored LED.
Eine einfache und betriebssicher Kontaktierung zwischen Leiterplatte und Sockel erzielt man dadurch, daß die Leiterplatte T-förmig mit einem Fuß und einem Querbalken ausgebildet ist, wobei sich der Fuß über eine vorbestimmte Strecke in den Sockel hinein erstreckt.A simple and reliable contact between the circuit board and base is achieved in that the circuit board is T-shaped with one foot and one Crossbar is formed, with the foot over a predetermined distance extends into the base.
Einen kostengünstigen und einfachen Aufbau eines erfindungsgemäßen Leuchtmittels erzielt man dadurch, daß die Leiterplatte eine Standardleiterplatte beispielsweise vom Typ FR4 ist. An inexpensive and simple construction of an illuminant according to the invention is achieved by making the circuit board a standard circuit board, for example is of type FR4.
Zweckmäßigerweise weist die wenigstens eine Leuchtdiode eine Betriebsspannung oder einen Betriebsspannungsbereich im Spannungsbereich von 6 V bis 230 V, insbesondere 12 V oder 24 V, auf.The at least one light-emitting diode expediently has an operating voltage or an operating voltage range in the voltage range from 6 V to 230 V, in particular 12 V or 24 V.
In einer bevorzugten Ausführungsform weist der Sockel einen Bajonett- oder Schraubverschluß zum Verbinden mit einer entsprechenden Leuchtmittelfassung auf.In a preferred embodiment, the base has a bayonet or Screw cap for connecting to a corresponding lamp holder on.
