High -life LED lamps

Abstract

The invention discloses a long-life LED lamp, which comprises a lamp housing, in which a base board is arranged; a lamp tube is arranged on the lower surface of the base board; cooling posts are arranged on both sides of the lamp tube; a lamp shade is arranged on the lamp housing; A light-emitting cavity is formed between the shells; the lamp shell and the lampshade are sealed and connected by sealant; the lampshade includes a PVC layer and a reflective layer arranged on the inner surface of the PVC layer. In the present invention, a reflector is arranged on the inner wall of the lamp housing to improve the reflection efficiency; an inert gas is arranged in the light-emitting cavity to improve its thermal conductivity, effectively reduce light decay, and improve light efficiency; a heat dissipation plate is arranged on the upper surface of the substrate to ensure that the heat dissipation plate can The remaining heat transmitted through the luminous cavity and the heat dissipation column is evenly and continuously dissipated, thereby preventing heat from accumulating on the heat dissipation column and causing local overheating; there are heat dissipation columns on both sides of the lamp tube to further improve the heat dissipation 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.
