Embodiment Construction

[0041] figure 1 An embodiment of an LED lamp (light-emitting diode lamp) 1 according to the invention is shown, which is suitable without retrofitting measures as a replacement for conventional fluorescent lamps and which can be installed in a lamp originally designed to accommodate e.g. L36W fluorescent lamps in conventional contact devices or sockets for fluorescent lamps or in lighting equipment. Therefore, the LED lamp 1 in this embodiment is a retrofit LED lamp, for example an L36W retrofit LED lamp.

[0042] A series circuit consisting of a choke coil 3 , which may also be bridged or removed, and the LED lamp 1 is connected between the two power supply terminals 2 , 16 , which can be connected to the public mains. The LED lamp 1 has contacts or sockets 4 , 5 , 14 , 15 which correspond to conventional arrangements and configurations of the contacts or sockets of the fluorescent lamps to be replaced. The contact 4 is connected to the inductor 3 , while the contact 14 is ...

Abstract

The invention relates to an LED lamp having a converter and an arrangement, connected to the converter, of light-emitting diodes arranged on at least one printed circuit board. The converter is arranged in a multi-part, latchable housing which completely surrounds the converter and is made of electrically non-conductive material.

Description

technical field [0001] The invention is based on an LED lamp. Furthermore, the invention relates to a lighting device equipped with such an LED lamp. Background technique [0002] Reference GB2465966A discloses a tubular LED lamp (LED, light emitting diode or device, a diode or device that emits light, also called a light-emitting diode), which can be incorporated into a fluorescent lamp of a lighting device as a substitute for a fluorescent lamp contacts or lamp sockets. The LED lamp has a transparent tube in which the linear LED arrangement is accommodated. Although this design provides good protection against undesired contact with parts of the LED arrangement used for current supply, it entails a poor thermal coupling of the LED to the surrounding environment, so that the cooling of the LED is compromised. This poor thermal coupling can lead to elevated operating temperatures, which in turn leads to lower light efficiency and shortened lifetime of the LED. In general...
