LEDs were produced as early as the 1960s. In the 1980s, it has been widely used in household appliances, such as volume indication and switch indication of audio. In the 1990s, some new domestic automobile instruments also used LEDs, mainly for charging instructions, and later displayed engine speed conditions, such as a combination instrument produced by Xiangfan, Hubei, a row of LEDs next to the odometer When the driver steps on the accelerator, the LED lights will turn on from bottom to top, and when the throttle is released, the LED lights will turn off from top to bottom, which is quite eye-catching and beautiful. In the mid-1990s, China used LEDs as high-level brake lights and installed them on cars. Because the LEDs light up quickly, the driver behind the car can know the driving status of the vehicle in front and reduce the occurrence of rear-end collision accidents.
The classification of LED car lights: mainly divided into external lamps and internal lamps. Common lights are: headlights, turn signals, rear lights, fog lights, back lights, etc. The maintenance and use of each main lamp are introduced one by one below.
In general, as long as it is not lit, it means that the bulb has burned out and must be replaced. But if it is not completely broken, but the brightness is reduced, the lights are red and dim, and you must not take it lightly, because this may be a precursor to the failure, and the reduced lighting ability is also a major hidden danger for safe driving.
There are several reasons for the decrease in brightness. The most common one is the accumulation of dust on the astigmatism glass or reflector of the lamp. At this time, all you need to do is remove the dirt with a velvet cloth or lens paper. Another reason is that the charging capacity of the battery is reduced, and the lack of power results in insufficient brightness. In this case, a new battery needs to be replaced. Another possibility is that the line is aging or the wire is too thin, causing an increase in resistance and affecting the power supply. This situation not only affects the operation of the light bulb, but also severely causes the line to pass through the heat and cause a fire.
Various types of car light maintenance methods:
Headlight:
Generally speaking, friends who often drive at night should consider replacing a pair of headlights with higher brightness, so that in the dark night, enough brightness can help you see all the details of the road, and when you hit the high beams, Can make you look further. If the premise permits, you can even replace a pair of xenon headlights (hid). Xenon lamps not only have sufficient brightness and long life, but also have a feature: the color temperature is very high, and the color temperature close to daylight is also a protection for the driver's eyes.
Rear lights:
Don't underestimate the rear light of the car. If the rear light fails, it will easily cause a rear-end collision. Generally speaking, as long as it is not a malfunction, there are few upgrade options for the taillights. In addition to installing a transparent lamp case to increase the viewing, it is a good choice to replace the traditional light bulb with LED luminous body. The traditional light bulb has been shortened, which means that when you press the brake pedal, the LED brake light can be lit earlier than the ordinary light bulb, so that the trailing vehicle has more preparation time.
Fog lights:
Fog lights are also commonly referred to as spot lights. As the name suggests, the main purpose of fog lights is to ensure the driver ’s sight under harsh weather, and to ensure that others can see you, and now there are many manufacturers, the purpose of installing fog lights is only to make the front bumper more beautiful, so The quality of the selected fog lamp is relatively poor. As with the headlamps, in addition to replacing the fog lamps with sufficient brightness, it is also a good choice to choose a pair of hid xenon fog lamps.
Backlight:
Reversing in the dark is really a headache, especially for drivers with poor eyesight. The faint light of the original reversing lights does not actually have much help. At this time, you need a pair of reversing headlights. This is an independent light fixture installed in the middle or below the rear bumper. It will automatically light up when you hang down the reverse gear. Its strong brightness makes you reverse the night. Never worry about it again.
18650 protected batteries have an electronic circuit.
The circuit is embedded in the cell packaging (battery casing) that protects the cell from [over charge", heat or [over discharge", over current and short circuit.
A 18650 protected battery is safer than an 18650 unprotected battery (less likely to overheat, burst or start on fire).
