Abstract: A LED light bar includes several LED light sources and a bar light source mounting base. The light source mounting base is made of an insulating and heat-conducting material. An electrical layer having several metal electricity-conducting plates is embedded in an inner part of the light source mounting base. The LED light sources are welded on the metal electricity-conducting plates to form an electrical electricity-conducting circuit. lighting sides of the LED light sources are exposed on a surface of the light source mounting base. The light source mounting base and the metal electricity-conducting plates are formed into a whole. Each LED light source is covered by lenses.

Abstract: A convective heat-dissipating light emitting diode (LED) illumination lamp includes a plurality of LED lighting heat-dissipating units (1), a base (2) for installing the LED lighting heat-dissipating units (1), and a frame (4). The base (2) is fixedly connected with the frame (4). The base (2) includes a plurality of strip-shaped members spacedly arranged from each other at a certain distance or the base (2) is a grid-shaped member for forming a hollow-out structure, so that a plurality of channels for direct convection with environmental air are formed in the base (2). The LED lighting heat-dissipating units (1) are spacedly provided on the strip-shaped members and the grid-shaped member. Each of the LED lighting heat-dissipating units (1) includes an LED chip, a circuit board, a circuit connecting member and a corresponding radiator, and forms an independent waterproof sealing body.
