LED lamp

Abstract

The invention discloses an LED lamp which comprises a lamp holder, a heat radiator, an electronic assembly and an LED lamp panel, wherein the lamp holder is connected with the heat radiator through a base, and the electronic assembly is arranged in an inner cavity formed by connecting the lamp holder with the heat radiator. The LED lamp is characterized in that the outer wall of the base is provided with a limit convex ring and a fixed groove, the limit convex ring is matched with the end face of a narrow hole of the heat radiator, the inner wall of the narrow hole end of the heat radiator is provided with a buckle ring, the buckle ring is matched with the fixed groove on the base; and the LED lamp panel is fixed on the opened end face of the heat radiator through a PC screw. The lamp holder and the heat radiator are connected through the base provided with the limit convex ring and the fixed groove, thus the connection part of the lamp holder and the heat radiator is avoided loosening and the use stability of the lamp is improved, the service life of the lamp is prolonged; meanwhile, the LED lamp panel and the heat radiator are fixed by using the PC screw for replacing the traditional metal screw, thus the short circuit caused by small distance between the screw and an LED is eliminated.

Description

technical field [0001] The invention relates to a lamp, especially an LED lamp. Background technique [0002] At present, most of the widely used indoor or outdoor lighting fixtures are incandescent bulbs or fluorescent tubes, but the efficiency of electro-optical replacement of these two products is relatively low, and they generate a lot of heat and have a short service life. [0003] After years of development and accumulation, LED lighting technology has shown excellent energy-saving effects. As an emerging semiconductor light-emitting element, LED light source has the advantages of small size, low energy consumption, low calorific value and long life. Therefore, LED light source Lamps are widely used. [0004] In order to facilitate the fixed connection of the lamp cap and the heat sink of the LED lamp, a base is used to fix the lamp cap and the heat sink in the structure of the LED lamps on the market now, but the above-mentioned structure is convenient for the instal...

Problems solved by technology

[0004] In order to facilitate the fixed connection of the lamp cap and the heat sink of the LED lamp, a base is used to fix the lamp cap and the heat sink in the structure of the LED lamps on the market now, but the above-mentioned structure is convenient for the installation of the lamp cap and the heat sink. It is not a direct connection. After a period of use, the connection between the lamp head and the radiator will become loose, which will affect the service life of the whole lamp. This is a technical defect in the production of LED lamps at this stage; there are also widely used LED lamps and lanterns, the LED substrate and heat sink are often directly fixed by metal screws, because metal is easy to conduct electricity and heat conduction, and the metal screws are too close to the LED light source during installation, which will cause short-circuit phenomenon in the LED during use.
