Previously, the editor has given you the disassembly report of the Tank 300 headlights produced by the lamp factory Mande Optoelectronics. Next, I will continue to bring you the disassembly report of the taillights.
In order to match the tough shape of the body, the taillights also adopt a square design language. In addition to the white piece, the entire taillight functions as a position light and brake light, and the outer side has a turn signal function. It can be seen that the designer is trying to minimize the reversing light. area. Although the overall shape is square, the designers still gave it a three-dimensional sense of depth with curvature in the X direction. It is retro but not old-fashioned, tough but not ostentatious. It can be said that it is very careful.
First, let’s take a look at the lighting effect of the actual object. It can be said that the uniformity is very good. There is also a WEY logo on the side of the thick wall. It is understood that this logo is made by corroding the skin on the side of the thick wall, which can be said to be full of details once again. When the brake light is on, you will find that the color of the position light is redder than the general position light. The editor understands that it is a customized super red light.
First remove the black outer decorative frame, which is connected to the lamp body using 3 screws + snaps. The installation and disassembly process is relatively simple.
The lampshade and lamp shell adopt the hot plate welding process. Judging from the width of the welding wall, the welding is relatively solid. (So it is easy to hurt your hands when disassembling).
As for the position of the middle brake light, it seems to be thick-walled at first glance, but it actually uses a hollow three-dimensional inner lampshade. The three-dimensional effect when this structure is lit is very beautiful, and the black decorative frame is made of two-color injection molding, and There are also some small designs in the black decorative frame, making the whole thing more refined.
The reversing light uses a small thick-walled piece, which is ultrasonically welded to the decorative frame.
After removing the decorative frame, the most eye-catching thing is these two large thick walls. According to the editor's actual measurement, the size of the thick-walled parts is 40mm*40mm*283mm. The two sizes are basically the same. Thick-walled parts of such a large size are also a big challenge. The editor is very curious. With two such similar thick-walled parts, aren't you worried about the workers installing them incorrectly?
After careful comparison, it was found that due to the different design of the holes, it cannot be installed if it is installed incorrectly. It seems that engineers have identified this risk in advance and made a reliable design. (FMEA is well written)
Below the thick-walled parts are two light guide plates. The two light guide plates are the same, so there is no need to worry about misinstallation. Careful observation reveals that the light guide plate and the black decorative parts on the upper side are not formed in one piece. The editor boldly guesses that a laser welding process is used here. It seems that Great Wall has spent a lot of money in pursuit of the lighting effect.
Continue to remove the two small thick-walled parts. I didn't pay special attention to them. Later I discovered that these two thick-walled parts were painted black to prevent light leakage. This can be regarded as the pursuit of perfection.
Similarly, similar to the error-proofing structure of the two thick-walled parts mentioned above, there is no misassembly problem between the two concentrators.
Now comes the step of disassembling the module assembly. Let me first give you a sneak peek at the internal direction of the wiring harness.
There is also a pack of desiccant hidden inside.
Next, it’s time to enlarge the move. After careful calculation by the editor, there are 36 LEDs for the position lights, 30 LEDs for the brake lights, 36 LEDs for the turn signals, and 6 LEDs for the reversing lights. It can be said to be a rich configuration, not short of money... so it can present a beautiful appearance. lighting effect.
Finally, a family photo.
After dismantling this taillight, the editor feels that although it is just a taillight, the materials and workmanship are still extremely solid. In terms of styling, design and manufacturing capabilities, domestic OEMs and lamp factories have already reached the first-class level.
According to the editor's understanding, in addition to Great Wall's business, Mande Optoelectronics has also recently stepped up its expansion of other car company businesses, aiming to become an excellent global automotive lighting supplier. We also hope that private enterprises can continuously improve themselves and do better and better!
