LED lamp with dual light sources

Abstract

The invention discloses an LED lamp with dual light sources. The LED lamp with dual light sources comprises a power supply module, a first light source, a second light source, a switching circuit, a pedestal, a first light transmitting hood and a second light transmitting hood; both the first light source and the second light source are mounted on the pedestal and are located on the same side of the pedestal; the first light source is composed of a plurality of LED chips which are successively connected in series and surround the periphery of the second light source; both the first light transmitting hood and the second light transmitting hood are mounted on the pedestal, the first light transmitting hood is arranged on the first light source and the second light source in a covering manner, and the second light transmitting hood is arranged on the periphery of the first light transmitting hood in a covering manner; and the switching circuit is separately connected with the power supply module, the first light source and the second light source, and is used for controlling the power supply module to supply power for the first light source or the second light source. According to the LED lamp with dual light sources disclosed by the invention, the switching circuit is arranged to automatically switch on the second light source to replace operation of the first light source under the condition that the first light source is abnormal, so that the LED lamp operates normally and inconvenience caused by the reason that the LED lamp cannot work is avoided.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a dual light source LED lamp. Background technique [0002] LED lights, also called light-emitting diodes, appeared in the 1960s. In the following decades, LED lights were generally used as indicator lights for electronic equipment such as tape recorders. Later, through the continuous efforts of developers, LED lights were gradually developed into lighting equipment. This kind of LED lamp has the characteristics of high efficiency and long life, and can be used continuously for 100,000 hours, which is 100 times longer than the life of ordinary incandescent lamps. [0003] With the gradual development of LED lights, LEDs have gradually replaced some traditional light source products in public places such as lighting engineering auxiliary lighting. In 2009, LED began to enter the main lighting popularization in developed countries, and was applied to commercial application p...
