Recently, the Shanghai Municipal Administration of Industry and Commerce concentrated on organizing forces to move, fixed and fixed to 25 supermarkets, 10 shopping malls, 9 professional markets and 25 batches in 5 areas of Baoshan, Hongkou, Jing'an, Putuo and Pudong. Embedded LED lamps have undergone market inspection and quality inspection. After testing, there were 3 batches that were unqualified, and the unqualified detection rate was 12%, down 13% year-on-year. The unqualified items are mainly the power terminal disturbance voltage and marking. First, the power terminal disturbance voltage is unqualified, there are 2 batches. The sampling found that the quasi-peak and average values ​​of the disturbance voltage of the power supply terminals of the unqualified products exceeded the standard limit. Exceeding the limit directly affects the surrounding broadcasting, the TV cannot be properly listened to, the viewing, and the instrumentation control fails. The disturbance voltage is a type of radio disturbance that jeopardizes the use of electrical appliances within the frequency band and creates environmental pollution. Second, the logo is not standardized and there is 1 batch. The sampling inspection found that the rated frequency information of the unqualified products was missing. According to national standards, LED lights should be clearly and durable marked with mandatory signs such as source mark, rated voltage or voltage range, rated power, and rated frequency. These information are important basis for consumers to decide whether to purchase. According to the results of the sampling inspection, the industry and commerce department has ordered the relevant operators to immediately stop selling unqualified commodities, comprehensively clean up the inventories and products for sale, implement rectification measures within a time limit, and urge the unqualified commodity operators to publicize in accordance with the requirements of relevant laws and regulations. Measures to protect the legitimate rights and interests of consumers, and legally investigate the operators who sell unqualified products. At the same time, the industry and commerce department reminds consumers to pay attention to the following points when purchasing, using and maintaining LED lamps: 1. When purchasing LED lamps, you should look at them three times. If the product identification is complete, the manufacturer's name, address, trademark, model specification, rated voltage, rated frequency, rated power, etc. should be checked. Check whether the product model matches the model specification of the inspection report and safety certification certificate. The identification is correct; secondly, whether the power cord of the lamp has the CCC safety certification mark, the cross-sectional area of ​​the external wire should be not less than 0.75 mm2; the third is to see if the charged body of the lamp is exposed. After the light source is installed in the lamp holder, the finger should not touch the charged metal lamp cap. 2. When purchasing LED desk lamps for children, avoid buying metal casing lamps with high heat source, such as incandescent lamps, tungsten metal lamps, and metal casing lamps; at the same time, pay attention to whether the lamps are stable enough, and tilt the lamps around 6 to see them. Whether it is overturned; choose a table lamp with a higher category of protection against electric shock, such as a Class II luminaire marked with a phrasing number. Third, after buying the lamps, you should carefully check the markings of the lamps and read the instructions for use, and then install and use them; when using LED lamps, if you find that the fluorescent tubes are red at both ends and the lamps are not lit, you should follow the signs of the light source. Replace the aging lamp in time; when cleaning and maintaining the LED lamp, pay attention to the instruction manual. In addition to removing the lamp cover cleaning lamp cavity or replacing the lamp tube, do not easily disassemble the other parts of the lamp, and at the end of cleaning and maintenance, install the lamp as it is.

Injection Charger Base Accessories
The design theme of the accessories for the injection charger base is the product design and mold design of the universal charger base, which is designed for the production of injection mold. Plastic parts
The preliminary analysis of the structure shows that the sprue and the sequence type, the structure and the adoption of a two-cavity mold are due to the large area of plastic parts. Due to the structural characteristics of plastic parts, it needs to use inclined sliding traction mechanism. The specific design process is as follows: first, the performance analysis of the plastic injection molding process. This includes analysis of the structural dimensions of the material properties of the plastic parts and molded plastic parts. Second, it is the choice of how to inject a reasonable machine. Choosing the right injection molding machine is the foundation of this design. Again, this is in the form of the mold structure preparation. The form structure of the mold must be calculated and a reasonable choice is based on the dimensions of the structure. The fourth step is to design the pouring system.
The fifth step is such a design in the design and mold parts of the calculation focus. The sixth step is to draw the sliding cover design of the oblique profile and the calculation of the core mechanism.
