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...

Abstract

The invention discloses a novel direct current lighting device capable of reversely connecting a positive electrode and a negative electrode. The novel direct current lighting device comprises a shell, a controller and a power supply access device, wherein the controller consists of a plurality of LED lamps and is arranged in the shell; the power supply access device is electrically connected with the controller; and the power supply access device is a semi-rectifying circuit. The power supply access device does not need to distinguish the positive electrode and the negative electrode by externally connecting the semi-rectifying circuit, so the condition of shortcircuit caused by misconnection of the positive electrode and the negative electrode is avoided.

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...
