Abstract

A light-emitting diode (LED) lamp comprises a first radiator, a second radiator fixed at the bottom of the first radiator, a plurality of LED modules attached to the second radiator and a lampshade which covers the second radiator and is fixed with the first radiator in a coordinated manner. The second radiator is provided with a plurality of heat conduction end faces which are hierarchically distributed and are different in sizes. The LED modules are correspondingly attached to the heat conduction end faces. The lampshade comprises a plurality of steps provided with concave lens structures and the steps are arranged corresponding to the LED modules. The light sent by the LED modules irradiates outwards after passing through the steps of the lampshade so as to obtain a larger lighting area. The steps of the lampshade are provided with concave lens structures, so that the light which is sent by the LED modules and has fixed direction is diverged after passing through the steps so as to obtain a larger lighting area.

Description

technical field

[0001] The invention relates to a light-emitting diode lamp, in particular to a light-emitting diode lamp providing a larger lighting area. Background technique

[0002] As an emerging third-generation light source, although it cannot replace traditional incandescent lamps on a large scale, it has the advantages of long working life, energy saving, and environmental protection, and is generally favored by the market. Moreover, the current modules composed of light-emitting diodes can produce high-power, high-brightness light sources, so they will widely and revolutionaryly replace existing light sources such as traditional incandescent lamps, and then become the main light source that meets the theme of energy conservation and environmental protection.

[0003] As the power and brightness of LEDs or their modules increase, the heat generated by them will also increase. If the heating problem of LEDs cannot be properly resolved, the working life of LED lamps w...
