The headlight upgrade is recommended to be close to the light
From the perspective of the frequency of use of the lights, the use time of the low beam is higher than the use time of the high beam. For example, the city night driving usually requires the use of low beam, while the use of the high beam is mostly concentrated in the night highway. Moreover, compared with the high-bright high beam, most of the vehicle's factory-equipped halogen low beam illumination effect is too poor, not only the dim light, but also the light is not focused, the illumination distance is short, which is not conducive to the safety of driving at night. Therefore, experts suggest that if the headlights are to be upgraded first, the low beam lights will only improve the lighting effect of the low beam lights, and the safety of night driving will be more secure.
Modified low beam, recommended LED headlights
Want to modify the low beam, most of the owners are also facing the problem of "modifying xenon lamps, or LED headlights." In this regard, industry experts recommend LED headlights. Experts said that although the Xenon lamp is the most widely used car in the current modification market, and its ultra-high brightness is also the most desirable advantage of most modified car owners, but from the perspective of modification, Xenon lamp conversion circuit is more complicated, if it is not easily modified The line accident is caused. On the other hand, the brightness of the xenon lamp is too high. It is easy for the low beam to cause visual fatigue to the driver and other drivers of the car, and it will cause visual blind spots, which are not conducive to safe driving. In contrast, some of the LED headlights available for retrofitting on the market are more suitable for retrofitting low beam lights. The "first mover" LED headlights introduced by Shellett are designed for low beam lights, and the market response is very good. In terms of brightness, LED headlights are brighter than halogen lamps but have no super bright glare effect of xenon lamps, which can be used to avoid driving fatigue while brightening. In addition, the conversion of LED headlights is relatively simple. For some models, plug and play, they can be modified by themselves, and the modification is more convenient.
Modified LED headlights: heat is the key
The modification of LED headlights is related to the safety of driving at night, so the quality of LED headlights is critical. When you are remodeling, you can go to a professional modification shop or 4S shop for consultation, try to modify the LED headlights of well-known brands with excellent quality. Among them, the Snowlight LED headlights are typical representatives.
Industry professionals believe that the thermal performance of LED headlights is particularly important. LED headlights are extremely sensitive to temperature changes. If the LED lights are continuously lit at high temperatures, the power is low and the life is reduced. Therefore, the heat dissipation performance of the LED headlights determines the service life of the LED lamps to a certain extent. The snowlight LED car headlights use intelligent and efficient cooling system to solve the heat dissipation problem. By monitoring the operating temperature of the LED lamp to suppress the current, the cooling fan with the maximum speed of 7000 and a large air volume is configured to maximize the heat dissipation performance and protect the safe operation of the lamp. Moreover, it can greatly extend the service life, and the service life of up to 30,000H is about 10 times higher than that of xenon lamps.
Of course, industry experts also said that no matter what kind of lights are modified, they must comply with the requirements of relevant national laws and regulations, and must not be modified in violation of the law. Only in this way can we create a safe driving environment for ourselves and others.
Piezoelectric Elements For Inkjet Piezo Transducer
Piezoelectric ceramic ring
Applications: ultrasonic vibration tranducer for inkjet printer
Vibration mechanism of inkjet printer:
Generally, it is composed of piezoelectric ceramics and driving rods. By high-frequency electric excitation, piezo ceramics produce high-frequency ultrasonic vibration (above 60 kHz or higher), which is transmitted to the driving rod and generates high-frequency micro-displacement (back and forth expansion) at its front end.
Piezo ceramics components features :
1. High vibration amplitude and can withstand higher power.
2. The product has high reliability, strong maintainability, and is not easy to break down or off-line.
3. The frequency can be adjusted in a wide range, generally within the range of 10KHz.
