led energy-saving lamps

Abstract

An energy-saving LED lamp comprises a heat dissipation device, a light source module, an organic lens, a pressing frame and anti-dazzle glass, wherein the heat dissipation device comprises a heat dissipation plate and a plurality of heat dissipation fins; the heat dissipation fins are arranged on one side face of the heat dissipation plate and each provided with at least one curved surface structure; the light source module is arranged on the heat dissipation plate; the organic lens is arranged on the light source module in a covering mode; the pressing frame is arranged on the heat dissipation plate, and the light source module and the organic lens are accommodated in the pressing frame; and the anti-dazzle glass is used for shielding the organic lens. As each heat dissipation fin is provided with at least one curved surface structure, the heat dissipation surface area is larger, and the heat dissipation performance is better. The smooth surface of the anti-dazzle glass further has the self-cleaning function to a certain extent and is not prone to absorbing impurities like oil stains and dust in air, so that the organic lens is capable of maintaining high light transmittance in the long using process.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to an LED energy-saving lamp. Background technique [0002] In recent years, with the rapid development of LED light sources in the field of lighting, and with its advantages of long life, low energy consumption, and environmental protection, it has been accepted by more and more people, and is widely used in indoor and outdoor lighting, especially on roads. In the field of lighting, LED street lights and tunnel lights have generally replaced traditional high-pressure sodium lamps. [0003] Although the LED light source is recognized as having the advantage of long life, the life of the whole lamp will be restricted by the life of many other components. Organic materials such as polycarbonate (PC) and polymethyl methacrylate (PMMA) are currently widely used. For example, the lens made of different materials, after long-term exposure to wind and sun, it will turn yellow o...

Problems solved by technology

[0003] Although the LED light source is recognized as having the advantage of long life, the life of the whole lamp will be restricted by the life of many other components. Organic materials such as polycarbonate (PC) and polymethyl methacrylate (PMMA) are currently widely used. For example, the lens made of different materials, after long-term exposure to wind and sun, it will turn yellow or even appear slightly cracked, that is, the structure of the whole lamp has poor protection performance for the organic lens. The role of light distribution

At the same time, PC and PMMA organic material lenses exposed to the air are more likely to absorb impurities such as oil and dust in the air, resulting in problems of lower light transmittance and changes in light distribution.

[0004] Secondly, the heat dissipation performance of existing LED lamps is not ideal
