摘要:
The present invention relates to an LED streetlamp comprising: an integral housing having a light-emitting opening from which light is emitted at a bottom surface thereof and provided with an accommodation space at an inner side thereof; a power supply unit inserted into and fixed to the accommodation space through the light-emitting opening of the housing; a reflecting part inserted into and fixed to the accommodation space through the light-emitting opening of the housing to separate one part of the accommodation space at which the power supply unit is located from the accommodation space of the lower part of the one part, and reflecting light from a bottom surface thereof; a substrate for supplying power to multiple LEDs provided by being coupled and fixed to an inner side surface of the housing of a lower side of the reflecting part; and a cover part for covering the light-emitting opening of the housing. The present invention manufactures a case with a single structure and provides parts such as the power supply unit, the substrate having the LEDs provided thereon, and the reflecting plate so as to be assembled in the case through the light emitting opening, thereby minimizing a manufacturing cost, and thus speeding up commercialization of LED lamps.

Eine Linearleuchte (1) umfasst ein Leuchtmittel (4), ein Betriebsgerät (5) zum Betreiben des Leuchtmittels (4) und ein einteiliges Trägerprofil (2). Das Trägerprofil (2) umfasst zwei längsförmige Grundplatten (211, 212), die jeweils zwei Längsseiten und zwei Stirnseiten aufweisen. Die zwei Grundplatten (211, 212) des Trägerprofils (2) weisen jeweils eine der anderen Grundplatte (211, 212) zugewandte innere Oberfläche und jeweils eine der anderen Grundplatte (211, 212) abgewandte äussere Oberfläche auf. Die eine der äusseren Oberflächen der zwei Grundplatten (211, 212) des Trägerprofils (2) bildet eine Vorderseite (214) des Trägerprofils (2) und die andere der äusseren Oberflächen der zwei Grundplatten (211, 212) des Trägerprofils (2) eine Rückseite (213) des Trägerprofils (2). Das Leuchtmittel (4) ist an der Vorderseite (214) des Trägerprofils (2) und das Betriebsgerät (5) an der Rückseite (213) des Trägerprofils (2) montiert. Das Trägerprofil (2) weist zwei seitliche Verbindungsbereiche (28) auf, die jeweils die beiden Grundplatten (211, 212) an jeweils einer derer Längsseiten miteinander so verbinden, dass die Grundplatten (211, 212) voneinander beabstandet sind und dass ein Hohlraum (27) zwischen den beiden Grundplatten (211, 212) angeordnet ist. Insbesondere umfasst das Trägerprofil (2) zwei Einschnitte (23), die sich jeweils zwischen einem der beiden Verbindungsbereiche (28) und einer der beiden mit ihm verbundenen Grundplatten (211, 212) entlang der zugehörigen Längsseite erstrecken. Damit kann eine Wärmeübergang von der einen Grundplatte auf die andere Grundplatte vermindert oder gar unterbunden werden. Die erfindungsgemässe Ausgestaltung des Trägerprofils (2) ermöglicht also auf einfach Art und Weise eine verbesserte effiziente thermische Trennung von Betriebsgerät (5) und Leuchtmittel (4).

摘要:
The present embodiments provide channel letter lighting devices and/or systems. A lighting system, comprising a plurality of electrically connected lighting units, comprising conductors to provide an electrical signal to each of the units. Each of the lighting units comprise a housing, a printed circuit board (PCB) mounted within the housing and having a plurality of tabs and a plurality light emitting elements on the tabs. The tabs are angled in relation of the remainder of the PCB or housing. The electrical signal applied to the light emitting elements causes them to emit light substantially away from said housing. The lighting system further comprises a sealant within the housing filling cavities around the light emitting elements and the cavity around said PCB and a mounting mechanism for mounting the unit to a structure.

摘要:
A plurality of LEDs are provided to an outer edge side of a center position of one main surface of an LED substrate main body in a deviated manner respectively. The wiring part including the connector receiving part and the wiring hole are provided at a position that overlaps the center position of the one main surface side of the LED substrate main body. Since the power feeding part is inserted into the wiring hole, the connection part and the connector receiving part can be easily connected and therefore it becomes possible to ensure ease in assembly. Since the connector receiving part is kept away from each of the LEDs with substantially equal distance so that emitted light is hardly blocked, decrease in uniformity of light distribution can be suppressed.
