[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0023] REFERENCE Figures 1-4The utility model provides an embodiment: a kind of driving lamp and side turn signal lamp integration, including lamp body 7, one side embedded with radiator 6 in lamp body 7 inside, PCBA circuit board 5 is installed with multiple bolts on the outer wall of radiator 6 side, light bar 4 is embedded with on the upper end surface of lamp body 7 side, cover plate 3 is arranged with by ultrasonic welding on the upper end of light bar 4 outer side of lamp body 7, lamp shade 2 is arranged with by vibration friction welding on the upper end of lamp body 7, bubble cotton 1 is embedded with on the upper end surface of lamp shade 2.
[0024] Specifically, the automobile body end transmits electrical signals and opening signals to the outside rearview mirror assembly through the interface, and the outside rearview mirror assembly transmits the signals to the PCBA circuit board 5. When the automobile enters the automatic driving state, the input is an automatic driving signal, and the automatic driving indicator light outputs a cyan blue light source. The cyan blue light source is transmitted to the light exit surface of the lamp shade 2 through the light bar 4, and a continuous cyan blue light is seen outside the vehicle. When the automobile is turning, the input is a steering signal, and the turn signal outputs an amber flashing light source. The amber light source is transmitted to the light exit surface of the lamp shade 2 through the light bar 4, and a flashing amber light is seen outside the vehicle. After the steering is completed, the turn signal light source is turned off.
[0025] The light bar 4 is located on one side of the circuit board. When the lamp beads on the circuit board emit light, the light source can extend outward along the light bar 4, forming a long linear light, which better displays and reminds passing vehicles.
[0026] Referring to Figure 1 The PCBA circuit board 5 includes two amber beads, six blue-green light beads, and a circuit board body.
[0027] Further, referring to Figures 1-4 The lamp shade 2, the cover plate 3, the light bar 4, and the lamp body 7 are all made of single-color injection molding.
[0028] Specifically, the lamp shade 2, the cover plate 3, the light bar 4, and the lamp body 7 are smooth on the surface, improving the overall aesthetic appeal, facilitating the uniformity of color and material, and helping to achieve a simple and unified product style.
[0029] Referring to Figure 2 The lamp shade 2 is made of PMMA material.
[0030] Specifically, PMMA acrylic resin has high transparency and light transmittance, can effectively diffuse light, improve lighting effect, has good ultraviolet resistance and weather resistance, is suitable for outdoor or environments that need to withstand sunlight, and is easy to injection mold, facilitating the manufacture of complex lamp shade 2 shapes. It has good impact resistance and is not easy to break, providing better use safety.
