ABSTRACT:
An LED lamp structure includes a housing, a support, an LED light source, a light source driving circuit board, a lens, and a cover. The housing has a horn-like shape with a converged end and a flared end, wherein the flared end is formed with an accommodation chamber; the converged end is arranged with a support, and the accommodation chamber receives an LED light source, a light source driving circuit board, and a lens; and the cover is engaged with the flared end of the housing. Given that the light source driving circuit board is located at the flared end of the housing with a larger space. As such, an improved cooling effect can be obtained and that the electronic components can be more durable and reliable. And the lens has a predetermined illuminating angle, so that a desirable illumination effect on the LED light source can be obtained.
