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 new DC lighting device with positive and negative poles reversely connected have positive and negative poles, which leads to poor general performance of the new DC lighting device with reversely connected positive and negative poles.

Embodiment Construction
[0011] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings, with reference to figure 1 In this embodiment, the novel direct-current lighting device whose positive and negative poles can be reversed includes a housing 1 , a controller 2 disposed in the housing 1 , and a running light power supply connection device 3 electrically connected to the controller 2 . The housing 1 includes a rear cover 1-2, and the running lamp power connection device 3 is arranged in the rear cover 1-2, and the rear cover 1-2 is provided with a ventilation device 1-3 for heat dissipation. The controller 2 includes a controller and a number of LED lights installed on the controller. The LED lights can be arranged in multiple stages, which can increase the coverage area of the lights and enhance the intensity of the lights. This embodiment is set to three levels . The first-stage LED lamp of the controller 2 is a triangular LED lamp 2-2, w...

The invention discloses a novel direct-current lighting device allowing the positive anode and the negative anode inversely connected. The novel direct-current lighting device allowing the positive anode and the negative anode inversely connected comprises a shell, a controller and a power connection device, wherein the controller comprises a plurality of LED lamps and is arranged in the shell, the power connection device is electrically connected with the controller, and the circuit of the power connection device is a half wave rectifying circuit. According to the universal car front lighting system, because the half wave rectifying circuit is externally connected, distinguishment between the positive anode and the negative anode of the power connection device is not needed, and it can be avoided that short circuit happens because the positive anode and the negative anode are wrongly connected.
Description
technical field [0001] The invention relates to an automobile lamp. In particular, it relates to a novel DC lighting device in which positive and negative poles can be connected in reverse. 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 diodes in the T20 car lamp using LED lights, the new type of DC lighting device whose positive and negative poles can be reversed has positive and negative poles, resulting in poor general performance of the new type of DC lighting device whose positive and negative poles can be reversed. [0003] Therefore, we need a new type of DC lighting device with low energy consumption, long life, and good general performance, and...
