Abstract: An LED lamp includes a heat sink and a plurality of LED modules. The heat sink includes a base and a plurality of supporters extending from a top face of the base. Each supporter has an inclined supporting face facing an adjacent one of two opposite lateral sides of the base. Each LED module is mounted on an inclined supporting face of a corresponding supporter. The supporters have extending heights gradually increasing along a horizontal direction from the two opposite lateral sides toward a center of the base. Angles between the base and the supporting faces of the supporters are acute angles and gradually decrease along the horizontal direction from the two opposite lateral sides toward the center of the base.

Abstract: An exemplary illumination device includes a heat sink, a plurality of LED modules mounted on the heat sink, an envelope engaged with the heat sink and covering the LED modules, and a reflector positioned on the envelope. Light generated by the LED modules emits forward through the envelope out of the illumination device and has a main emission direction. The reflector reflects the light back to a direction sideways and opposite to the main emission direction to increase an illumination area.

Abstract: An LED lamp includes a monolithic housing made of metal extrusion and comprising a heat sink and a receiving portion integrally extending from a bottom of the heat sink, a plurality of LED modules attached to the heat sink, a cover covering the LED modules and a supporting bracket mounted on the housing. The heat sink includes a planar base and a plurality of fins extending from a top face of the base. The receiving portion includes a frame defining a window at a center thereof and two sidewalls interconnecting the frame and the base. The frame, the sidewalls and the base cooperatively define a receiving chamber for accommodating the LED modules therein. The LED modules are attached to the base and located corresponding to the window of the frame. The cover is mounted on a bottom of the frame and correspondingly covers the window.

Abstract: An LED module includes an LED and an elongated lens. The lens includes a center axis, a concave incident face, and an opposite convex emitting face. The emitting face includes a portion with a curvature radius at any point along a first plane larger than a distance between the point and the LED, and larger than a curvature radius at a corresponding point of the incident face on the first plane. A curvature radius at any point of the portion of the emitting face along a second plane perpendicularly intersected with the first plane at the center axis is larger than a distance between the point and the LED, while smaller than a curvature radius of a corresponding point at the incident face on the second plane. A radiating angle of the LED module in the first plane is larger than that in the second plane.
