Abstract

An LED lamp includes a hollow housing, at least one circuit board, several LED, two conductive plates and a cap. The LED are mounted under a bottom face of the circuit board. The circuit board and the LED are all installed in the housing with the LED located at a bottom end of the housing. The conductive plates are mounted in the housing. The top ends of the conductive plates protrude from a top end of the housing, while the bottom ends of the conductive plates are electrically connected with the circuit board. The cap is detachably fitted on the top end of the housing. The LED lamp is inbuilt with LED so that it is unnecessary to further install any LED bulb. Multiple LED lamps can be easily serially connected to increase the brightness.
