Abstract

An LED double-side line light comprises an aluminum alloy stretching housing, an LED lamp and a mounting frame. The transverse cross section of the housing adopts an inverted trapezoid surface; two sides of the housing adopt concaved inclined surfaces, wherein a high-power LED lamp component is arranged in the concave surface on one side and a low power LED lamp component is arranged in the concave surface on the other side; waterproof end cover components are arranged at two end surfaces of the housing; and the top surface of the housing and the mounting frame are connected. The transverse cross section of the aluminum alloy stretching housing is designed into an inverted trapezoid surface, which can improve the integral leak-proof effect; outwards-opened rectangular heat dissipation grooves are formed on the top surface, the bottom surface and the side surfaces of the stretching housing, which facilitates the heat dissipation at the outer peripheral of the housing and quickens the temperature reduction of the lamp body; the bottom plate of the double-side LED lamp component is separated by a middle cavity to reduce heat efficiency and temperature rise, therefore, the improvement of the LED luminescence efficiency and the prolonging of the service life of the LED lamp are facilitated; and the lamplight projection direction can be adjusted through the rotation of the movable bracket, and double effects of projection light and outline lighting are achieved. The operation is convenient and the use is safe and reliable.
