Embodiment Construction

[0015] The specific embodiment of the present invention will be described below in terms of circuit and structure in conjunction with the accompanying drawings.

[0016] The schematic diagram of brake light circuit of the present invention is as follows: figure 1 Shown: Diode D1 is used for rectification of the circuit and at the same time plays a protective role after the positive and negative poles are reversed due to misoperation. Capacitor C1 is used for filtering and buffering during turn-on, turn-off and floating input voltage. Transistors Q1, Q2, Q3, Q4, diode D2, Zener tube D3 and resistors R1, R2, R3, R4, R5 are the 12V / 24V drive part, which is used to adjust the connection mode of LEDs under different input voltages of 12V and 24V. Resistors R6, R8, and R10 are current limiting parts for setting the current of the LED. LED1-LED6 is the LED part, a total of 6 LEDs, divided into two groups of LED1-LED3 and LED4-LED6, when 12V is input, the two groups are connected in...

Abstract

The invention belongs to the LED automobile lamp technical field and relates to a universal LED rear combined lamp illuminator for 12V/24V. The illuminator is composed of a brake lamp, a rear positionlamp, a rear turn lamp and a license plate lamp. According to circuit design, the magnitude of an input voltage is compared with the magnitude of the voltage of a voltage-regulator tube, so that theturning on and turning off of different triodes can be controlled, and therefore, the connection modes of LEDs under different input voltages of 12V and 24V can be adjusted; the current of the LEDs iscontrolled through using a resistor current limiting mode; and a current-limiting resistor used during 24V driving can be also used during 24V driving, and therefore, the rear position lamp and the license plate lamp can be turned on simultaneously. According to PCB structure design, a circuit board comprises a main board and a license plate lamp board; and the license plate lamp board is vertically inserted and soldered on the main board, so that an integrated lamp board can be formed.

Description

technical field [0001] The invention belongs to the technical field of LED automobile lamps, and in particular relates to a 12V / 24V universal luminous body for LED rear combination lamps. Background technique [0002] With the continuous development and maturity of LED manufacturing technology and the gradual decline of production costs, LED light sources have begun to be widely used in automotive lights, special lighting fixtures, public lighting and other fields. They have huge development potential and are considered to be the most Light source for development prospects. [0003] As an essential safety component for automobile driving, automobile lamps play an important role in the active safety of automobiles. LED has the advantages of strong reliability, long service life, high color purity, fast response, small size, easy design, and excellent changes in the appearance of automobiles, making it more and more widely used in exterior lighting. In the 21st century, LED ...
