If it is the discovery of electricity that allows mankind to move from the first industrial revolution to the second industrial revolution, then the creation of lamps is a superfluous addition. There is an important part in modern LED lamps, called ballasts. Today, we will take a look at the ballasts.

First, the lamp ballast effect

1. Energy-saving effect The lamp ballast generally uses 20-60 Hz frequency to supply power to the lamp to ensure that the user can use the lamp normally and continue to illuminate, so that the corresponding light efficiency and power frequency of the lamp are improved by 10%. The lower the light, the power of the lamp will also drop by 20%, it has a certain energy saving effect.

2. Reject the light. (1) The ballast has the strobo light to remove the strobe, so that the illuminating illumination of the luminaire will not affect the user's application, nor will it reduce the human eyesight, which will bring inconvenience to the lighting. (2) Assuming you are in an unstable lighting and uninterrupted flashing, you will definitely feel uncomfortable and affect the officer.

3. Preheating function (1) At the moment when the lamp switch is turned on, there is a large instantaneous current passing through the lamp, which may bring different degrees of damage to the lamp. If the ballast is used to relieve the preheating process, the wear may be reduced. . (2) The ballast gives the lamp a buffering moment, which reduces the instantaneous impact of the current on the lamp bulb and prolongs its application time.

Second, the ballast device approach

1. Preparation (1) First look at the type of lamps, generally have their own lamp ballasts, if it is more damaged now, you can buy a ballast of the same type. (2) According to the flow of the lamp device, look at the ballast device process, prepare the corresponding tools, and then construct.

2. Device details. The electronic ballast can be fixed in the horizontal or vertical direction on the electric board of the induction lamp. If it is a low-frequency electrodeless ring or a square tube bracket, it needs to be fixed with screws. The nut should be added with a shrapnel gasket, 0 tube bracket plane and Reflective 0 device contact surface should be adhered to tightly coupled, it is best not to have a gap, after the device to view.

3. Wiring rules. (1) 110V/220V/277V ballast should be connected to the AC power line is red, green or yellow (ground), blue, white two straight straight lamps. (2) The 12VDC/24VDC ballast is connected to the DC power cable as red, green or blue (-), and the two white wires are connected to the lamp. Xiaobian said the lamp ballast device method, its process is relatively brief introduction, first familiar with the details of the device, wiring method, and then according to the operation, generally can be properly repaired. In the lamp ballast device, it is necessary to find out the effect of the lamp ballast device. If there are problems in the future, the type of ballast to be purchased must match the type of the lamp, and there can be no difference.

USB HUBS

The USB HUBS is also known as a port replicator which is an external device designed for laptop computers. By copying or even extending the port of the notebook computer, the notebook computer can be easily connected with multiple accessories or external devices (such as power adapter, network cable, mouse, external keyboard, printer and external monitor) in one stop.

The USB C Hubs has both the functionality of a port replicator and is used to extend to a considerable degree of desktop functionality. Especially suitable for professionals, such as the need for more interface equipment. Using the laptop docking station for company, home or business presentations can also increase the ease of use and excellent scalability of the notebook. For example, consider using the UltraBay interface on the docking station to obtain an optical drive, burner, battery, numeric keypad, hard disk and other expansion functions.

The biggest use of the mini Type C Usb Hub is port expansion. As it is known to all, laptop computers are much less than desktop computers due to their own size limitations, both in terms of the number of ports and types, and sometimes it is difficult to meet the needs of users. The mini dock, on the other hand, offers multiple port extensions, like a laptop that suddenly has three heads and six arms. Some ports are most laptops do not have their own, such as serial port, PS/2, DVI, IBM dedicated floppy drive port. Some are more numerous than the body of a laptop, such as USB ports. These numerous ports allow the laptop to connect to more peripherals at the same time, improving the performance of the entire laptop and helping to increase productivity.
