Abstract

The invention relates to an LED (light-emitting diode) lamp. The LED lamp comprises a heat sink (1), a light engine (2), an LED driver (3) and a driver housing (4) for containing the LED driver (3), wherein an isolating wall (A) is formed in the heat sink (1), the light engine (2) and the driver housing (4) containing the LED driver (3) are respectively arranged on the first side and the second side of the isolating wall (A), which are opposite to each other, wherein the LED lamp is also provided with a connector (5), which presses the light engine (2) on the first side of the isolating wall (A) and is locked along with the driver housing (4) on the second side of the isolating wall (A).

Description

technical field [0001] The invention relates to an LED lighting device. Background technique [0002] As we all know, LED lighting has irreplaceable advantages, such as energy saving, ultra-low power consumption, close to 100% electro-optic power conversion, the same lighting efficiency is more than 80% energy-saving than traditional light sources, and its life is longer. In view of the above advantages, more and more people use LEDs as light sources, such as a large number of LED retrofit lamps appearing on the market. This LED retrofit lamp has the outline of a traditional light source such as an incandescent lamp, so that it can be used as a light source to better adapt to an existing lighting system. [0003] An LED retrofit lamp is disclosed in the prior art, the LED retrofit lamp has: a driver housing for accommodating the LED driver; a radiator, the radiator is fixed on the driver housing with one end, and The other end of the heat sink is in thermal contact with th...
