Abstract: LED lighting devices and fabrication methods are provided. An LED lighting device includes a heat dissipation lamp cup including a hollow structure, a driving power supply casing socket configured within the heat dissipation lamp cup to form a ventilation gap between the driving power source casing and an inner wall of the heat dissipation lamp cup, and a lamp holder configured on top of the heat dissipation lamp cup. The lamp holder includes one or more sidewalls forming a ventilation channel passing through the lamp holder. The ventilation channel is connected to the ventilation gap for air circulation. The LED lighting device also includes a substrate configured on an outer surface of each of the one or more sidewalls of the lamp holder and a plurality of LED light sources mounted on the substrate.

Abstract: A LED street lamp comprises a power source box at front section, a lamp holder at middle section and an end cap at end section. The lamp holder includes a turn-able framework, a frame fixing unit connected with frame to limit frame rotation and a several LED lighting modules installed side by side in the frame. A LED lighting module is turn-able to connect with the frame on which a module positioning unit is set to limit the rotation of LED lighting module. The LED street lamp base includes two bilateral symmetrical frames, each of which is set with several LED lighting modules side by side. Both angles of frame and LED lighting module are adjustable, therefore, the LED street lamp can be adjusted at any time according to practical street situation in order to ensure ideal street lighting brightness and evenness.

Abstract: The present invention relates to a LED street lamp, which consists of power source box at front section, lamp holder at middle section and end cap at end section. The above mentioned lamp holder is composed of turnable framework, frame fixing unit connected with frame to limit frame rotation and several LED lighting modules installed side by side in the frame. A LED lighting module can be turned to connect with frame on which module positioning unit is set to limit the rotation of LED lighting module. For LED street lamp base of the invention, the major design part contains two bilateral symmetrical frames each of which is set with several LED lighting modules side by side. Both angles of frame and LED lighting module are adjustable of strong practicality, and so we can adjust them at any time according to practical street situation in order to ensure ideal street lighting brightness and evenness.
