Problems solved by technology

The T20 car lamp with tungsten lamp can have no positive and negative poles, and has good general performance, but consumes a lot of energy and has a short life.
However, due to the characteristics of the diode, the T20 car lamp using LED lights makes the LED strip circuit board with components have positive and negative poles, resulting in poor general performance of the LED strip circuit board with components.

Abstract

The invention discloses an LED lamp band circuit board with elements. The LED lamp band circuit board includes a housing, a controller which is formed by a plurality of LED lamps and is arranged in the housing, and a power source access device which is electrically connected to the controller; and the power source access device is a semi-rectifying circuit. According to the invention, distinguishing of positive and negative electrodes of the power source access device can be avoided through the external semi-rectifying circuit, and then short circuit due to wrong access of the positive and negative electrodes can be avoided.

Description

technical field [0001] The invention relates to an automobile lamp. In particular, it relates to an LED strip circuit board with components. Background technique [0002] Existing car lights generally adopt two forms, one is to use tungsten lamps; the other is to use LED lights (light emitting diodes). The T20 car lamp with tungsten filament lamp can have no positive and negative poles, and has good general performance, but consumes a lot of energy and has a short life. However, due to the characteristics of the diode, the T20 car lamp that adopts LED lights makes the LED strip circuit board with components have positive and negative poles, resulting in poor general performance of the LED strip circuit board with components. [0003] Therefore, we need a LED strip circuit board with components that consume less energy, have a long life, and have good general performance. Contents of the invention [0004] Based on the deficiencies of the prior art, the problem to be sol...
