Embodiment

[0021] Such as figure 1 As shown, an LED lamp includes: a joint 1, a heat sink 2, an LED driver 3, an LED chip 4, a heat conduction substrate 9 and a lampshade 5, the lower end of the joint is connected to the upper end of the heat sink, and the LED chip is arranged on the heat conduction substrate The bottom surface of the heat-conducting substrate is further provided with a reflective layer 10 to increase the light extraction rate of the LED lamp and improve the brightness of the LED lamp. The heat-conducting substrate is connected to the lower end of the radiator, and the radiator and the lampshade are connected by buckles, which facilitates the installation and disassembly of the LED, and at the same time facilitates later maintenance. The heat sink is hollow and the outer wall is provided with finned heat sinks 6 . The LED driver is disposed in the inner cavity of the heat sink and is electrically connected to the connector and the LED chip respectively. The LED chips ar...

Abstract

The invention relates to a light-emitting diode (LED) lamp which comprises a connector, a radiator, an LED driver, an LED chip and a lampshade; the lower end of the connector is connected with the upper end of the radiator; the lower end of the radiator is connected with the lampshade; the radiator is hollow, and the outer wall of the radiator is provided with a radiating fin; the LED driver is arranged in the inner cavity of the radiator and is respectively connected with the connector and the LED chip electrically; the LED chip is arranged in the lampshade; the inner wall of the lampshade is provided with a phosphor layer. The phosphor layer is arranged on the inner wall of the lampshade, so that the phosphor layer is separated from the LED chip for a certain distance, the attenuation of phosphor at high temperature is reduced, and thus the service life of the LED lamp is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED lamp. Background technique [0002] Light Emitting Diode (LED) is a solid-state semiconductor electronic component that converts electrical energy into visible light. LED lights have the advantages of small size, low cost, low power consumption, and environmental protection, and have become the first choice for contemporary lighting. With the continuous advancement of LED technology and the continuous promotion of its application fields, LED related technologies have also been optimized and improved accordingly, such as the intelligent control technology of LED lights and the packaging technology of LED lights. [0003] However, the heat dissipation problem of LED lamps still seriously affects the service life of LED lamps. When the LED chip works, it converts a small part of electrical energy into light energy and converts most of the electrical energy into heat energy...
