HEAT DISSIPATION FACILITATING LED LAMP

摘要

LED lamp devices are provided. An LED lamp device includes a lamp head, 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 sidewalls forming a ventilation channel passing through the lamp holder. The ventilation channel is connected to the ventilation gap for an air circulation. The LED lamp device also includes a substrate configured on an outer surface of each of the one or more side-walls of the lamp holder and a plurality of LED light sources mounted on the substrate. The LED lamp device can combine an internal cooling process and an external cooling process for heat dissipation to reduce environmental temperature for the power supply to work, to ensure use life of the power supply. Heat generated by the LED lamp devices can be significantly scattered away to effectively reduce the temperature of outer surface of the heat dissipation lamp cup to protect human hands from being burned when the human hands touch the outer surface of the heat dissipation lamp cup.
