Abstract
Description
Technisches GebietTechnical area
Die Erfindung betrifft eine Weitwinkel-Beleuchtungsvorrichtung, die eine Weitwinkel-Beleuchtung erreichen und die Leuchtdichte und die Lichthomogenität erhöhen kann.The invention relates to a wide-angle illumination device that can achieve wide-angle illumination and increase the luminance and the light homogeneity.
Stand der TechnikState of the art
Da die globale Erwärmung immer schlimmer ist, spielt die energiesparenden Umweltschutzprodukte eine immer wichtigere Rolle. Die Glühbirne wandelt beim Leuchten 90% der verbrauchten Energie in Wärmeenergie um. Nur 10% der Energie wird in Licht umgewandelt. Dadurch ist der Wirkungsgrad niedrig, so dass die Energieverschwendung hoch ist.As global warming continues to worsen, energy-saving environmental protection products are playing an increasingly important role. When lit, the bulb converts 90% of the energy consumed into heat energy. Only 10% of the energy is converted to light. As a result, the efficiency is low, so that the waste of energy is high.
Um die Glühbirne zu ersetzen, wurde die Leuchtdiodenbirne entwickelt. Die Leuchtdiodenbirne weist die Vorteile von einer hohen Helligkeit, einem niedrigen Stromverbrauch, einer längeren Lebensdauer usw. auf. Beider Herstellung wird die Kohlendioxidemission verringert, wodurch die Kosten und die Verschmutzung reduziert werden.To replace the light bulb, the light-emitting diode bulb was developed. The light-emitting diode bulb has the advantages of high brightness, low power consumption, longer life, and so on. During production, carbon dioxide emissions are reduced, reducing costs and reducing pollution.
Die Leuchtdiodenbirne weist einen Gewindesockel, einen Leuchtkörper und ein Gehäuse auf. Der Leuchtkörper ist durch eine plane Schaltungsplatte und die Leuchtdioden auf dieser Schaltungsplatte gebildet. Die Leuchtdioden strahlt nur in einer Richtung das Licht aus. Da die Leuchtdioden einen Lichtwinkel von 120° besitzen, ist der Beleuchtungsbereich klein. Der Bereich um das Gehäuse und unter dem Gehäuse wird nicht ausgeleuchtet und ist somit dunkler. Daher ist die Beleuchtungswirkung schlecht.The light-emitting diode bulb has a threaded socket, a luminous body and a housing. The luminous element is formed by a plane circuit board and the light-emitting diodes on this circuit board. The LEDs only emit the light in one direction. Since the LEDs have a light angle of 120 °, the illumination range is small. The area around the housing and under the housing is not illuminated and is therefore darker. Therefore, the lighting effect is poor.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Weitwinkel-Beleuchtungsvorrichtung zu schaffen, die eine Weitwinkel-Beleuchtung erreichen und die Leuchtdichte und die Lichthomogenität erhöhen kann.The invention has for its object to provide a wide-angle illumination device that can achieve a wide-angle illumination and increase the luminance and the light homogeneity.
Diese Aufgabe wird durch die erfindungsgemäße Weitwinkel-Beleuchtungsvorrichtung gelöst, die mindestens einen Sockel, einen Pyramidenkörper, ein Befestigungselement, mindestens eine Leuchtdiode und ein Gehäuse umfasst, wobei das Befestigungselement den Pyramidenkörper auf dem Sockel befestigt, wobei der Pyramidenkörper mindestens drei Seitenflächen und eine dreieckige Grundfläche aufweist, wobei die Leuchtdioden auf der Grundfläche und den Seitenflächen angeordnet sind, wobei das Gehäuse mit dem Sockel verbunden ist.This object is achieved by the wide-angle illumination device according to the invention, which comprises at least one base, a pyramid body, a fastening element, at least one light emitting diode and a housing, wherein the fastening element fixes the pyramidal body on the base, wherein the pyramidal body at least three side surfaces and a triangular base wherein the light emitting diodes are arranged on the base surface and the side surfaces, wherein the housing is connected to the base.
Da die Grundfläche und die Seitenflächen auf unterschiedliche Richtungen gerichtet sind, wird der Beleuchtungsbereich der Leuchtdioden vergrößert, so dass eine Weitwinkel-Beleuchtung erreicht wird. Zudem kann die Leuchtdichte und die Lichthomogenität erhöht werden.Since the base and the side surfaces are directed in different directions, the illumination range of the LEDs is increased, so that a wide-angle illumination is achieved. In addition, the luminance and the light homogeneity can be increased.
