Long-service-life LED lamp

Abstract

The invention discloses a long-service-life LED lamp. The long-service-life LED lamp comprises a lamp housing; a substrate is arranged inside the lamp housing; the lower surface of the substrate is provided with a lamp tube; the two sides of the lamp tube are each provided with a heat radiating column; the lamp housing is provided with a lampshade; a light emission chamber is formed between the lampshade and the lamp housing; the lamp housing is hermetically connected with the lampshade by adopting sealing glue; and the lampshade comprises a PVC layer and a reflecting layer which is arranged onthe inner surface of the PVC layer. According to the long-service-life LED lamp disclosed by the invention, a reflecting part is arranged at the inner wall of the lamp housing in order to improve thereflection efficiency; insert gas is arranged inside the light emission chamber so that the heat transfer property of the lamp is improved, light attenuation is effectively reduced and the light efficiency is improved; the upper surface of the substrate is provided with a heat radiating plate to make sure that the heat radiating plate can be used for uniformly and continuously emitting the residual heat after the heat is transferred through the light emission chamber and the heat radiating columns, and thus the heat is prevented from being accumulated on the heat radiating columns, and the phenomenon of local overheating can be prevented; and the heat radiating columns are correspondingly arranged at the two sides of the lamp tube in order to further improve heat radiation of the lamp tube.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a long-life LED lamp. Background technique [0002] LED light is a novel light source that has rapidly emerged in recent years. It is the fourth generation of new light source after incandescent fluorescent lamp high-intensity discharge lamp. Solid-state lighting based on white LED is a typical green lighting method. Compared with traditional light sources It has many characteristics such as energy saving, environmental protection, long life, small size, safety and reliability, and fast response speed. It represents the future of lighting technology and meets the requirements of "building a resource-saving and environment-friendly society" proposed by the current government. At present, it has been widely used in various aspects such as urban landscape decoration, traffic signals, commercial advertisements and home lighting. In recent years, with the continuous development of ...

Problems solved by technology

[0003] Since LED is a typical point light source, it must be converted into a surface light source with uniform illumination to exert a soft lighting effect. However, the light transmittance and haze of the lampshade used in people's daily life are not high, and there is a relatively large part of the light. Energy is lost, resulting in poor overall lighting

At the same time, long-term use of existing LED lamps tends to generate a large amount of heat, and the heat is not easy to dissipate from the LED lamp, causing the LED lamp holder to heat up. When the heat reaches a certain temperature, the LED lamp is easily damaged, affecting the service life of the LED lamp, and the use effect is poor.
