So far, the overclocked three-spot light kit has produced 30 models of three generations. Stylish and exquisite shape design, noble and classic temperament, destined to be a high-value series. However, the floodlight kit clearly depends on the value of the face, but it depends on the strength!
Floodlights are widely used in indoor and outdoor lighting in shopping malls, exhibition halls, parking lots, stadiums, billboards, buses, sculptures, and national lighting projects. When the outdoor lighting is used, the external environment is more complicated. In addition to the influence of rain and strong winds, the dust and dust factors cannot be ignored, especially the dusty weather in the northern part of the country from March to May. If the luminaire does not have the ability to withstand these natural weather for a long time, it may cause malfunction or damage to the luminaire.
Xiaobian asks the professional to carry out the dust test on the finished lamp of the floodlight. The test object is the overclocked three-projection light kit TG50-A.

First, the test method
Test according to GB-T2423.37-2006 Test L, La2 Type 2 test method.
Second, the purpose of the test
The dust TG50-A is tested for its ability to protect against dust by simulating the impact of outdoor dust on the product through a dust test chamber.
Third, the sample situation
The test sample is an assembled TG50-A finished lamp with a sample power of 50W, as shown in the following figure:

Fourth, the test process
1. Put 2KG dry talcum powder into the test chamber;
2. Before the product is tested, it should be placed in a normal temperature atmosphere for about 2 hours;
3. Place the sample on the shelf in the dust box (centered);

4. Set the test parameters and start the test;
5. After 8 hours, the test is completed, take a sample, turn off the power, and let stand for 2 hours to wait for sand and dust to precipitate;
6. Use a brush to clean the fine dust on the surface of the sample in the test chamber, and then take it out and blow it off with a wind gun;
7. Check that the sample is lit normally and disassemble the glass to see if it is invading the dust.

Five, test results
The blown TG50-A sample was energized, the sample was lit normally, and the lamp bead was not flickering. Remove the glass and visually invade without dust. As shown below:

Visual inspection
Conclusion
The floodlight TG50-A is tested according to GB-T2423.37-2006 test L, La2 type 2 test method. After 8 hours of sand dust test, the sample is normally lit, the glass is opened, and no dust is entered inside the silicone ring.
In this test, it is done under laboratory conditions, considering only the effects of wind and fine sand, and there is rainwater in the actual environment, and sandstone with larger diameter will also have an effect on the product. Therefore, the test conditions and actual conditions may have slightly different effects on the product.

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.
