Embodiment 1

[0022] As shown in FIG. 2 , the present embodiment is a circuit of a single-ended red light rear bulb. The circuit is composed of a protective resistor 6 connected in series with several red light emitting diodes 7 to form a lighting chain circuit 8 . When the rear position voltage signal is input, the circuit is connected, and the light-emitting diode 7 emits red light, thereby realizing the red light signal indication of the rear position lamp.

Embodiment 2

[0024] As shown in FIG. 3 , this embodiment is a circuit for a single-ended yellow light steering bulb, which is composed of two parallel light-emitting chain circuits 8 and 9 . When the steering voltage signal is input, the circuit is connected, and the two light-emitting chain circuits 8 and 9 emit yellow light at the same time, thereby realizing the yellow light signal indication when turning.

Embodiment 3

[0026] As shown in FIG. 4 , the present embodiment is a single-ended red light brake bulb circuit. The circuit is composed of two parallel lighting chain circuits 8 and 9 , and a regulator tube 10 is connected in series at the front end of the parallel lighting chain circuits. When the brake voltage signal is input, the line is connected, and the two light-emitting chain circuits 8 and 9 emit red light at the same time, thereby realizing the red light signal indication during braking.

Description

technical field [0001] The invention relates to an automotive indicator light bulb, in particular to an LED solid automotive indicator bulb. Background technique [0002] Existing automotive light bulbs are generally filled with inert gas or vacuumized, and are called gas light bulbs. This type of incandescent lamp not only has poor brightness and high power consumption, but also has a short service life and is not shock-resistant, resulting in a high damage rate. At present, these shortcomings of automobile indicator lights have caused great road traffic safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an LED solid automobile light bulb, which uses LED light-emitting diodes as light sources to overcome the above-mentioned shortcomings of existing similar products. [0004] In order to solve these technical problems, the present invention adopts the following technical solutions. [0005] An LED...
