Abstract

The invention relates to a dummy load system for an integrated LED (Light Emitting Diode) steering lamp, which comprises a steering switch, a pair of intelligent dummy load control circuits and a set of steering lamps; the output end of the steering switch is respectively connected with the input ends of the pair of intelligent dummy load control circuits; the output ends of the pair of intelligent dummy load control circuits are respectively connected with the set of steering lamps; and the steering switch, the pair of intelligent dummy load control circuits and the set of steering lamps are respectively connected with a vehicle power supply. In the invention, one dummy load manages a left and a right steering lamps so that the whole vehicle only needs two dummy loads; therefore, half space is saved, large-power components such as resistors and large-scale heat dissipating structure are saved, and the weight is reduced; moreover, the dummy load system for an integrated LED steering lamp is simple in structure, low in cost, small in volume, convenient to manufacture and easy for popularization and application.

Description

technical field [0001] The invention relates to a dummy load, in particular to a dummy load system integrating LED turn signals. Background technique [0002] In recent years, more and more LED signal lamps have been used in the automotive field. LED lamps have a series of advantages such as energy saving and longevity, but not many are used in automotive turn signals. Because automotive LED steering lamps must be equipped with a dummy load to meet the detection system of the bulb. [0003] Each vehicle needs four dummy loads, namely front left, rear left, front right and rear right. Each turn signal requires a dummy load. When turning left, the two dummy loads on the left work, and the two dummy loads on the right are empty, which greatly wastes components, costs too much, occupies a large volume, and increases the weight accordingly. [0004] At present, a dummy load circuit system of the prior art, the dummy load circuit system includes: a vehicle voltage source, a lig...
