Working principle of solar street lights: During the day, solar street lights are controlled by intelligent controllers.  ​smart solar street light ， Solar panels absorb sunlight and convert it into electricity when exposed to sunlight. The light source is energized to realize the lighting function. The DC controller can ensure that the battery pack is not damaged due to overcharge or overdischarge, and has functions such as light control, time control, temperature compensation, lightning protection, and reverse connection protection. Solar street light - system composition The solar street light system can ensure normal operation in rainy weather for more than 15 days! The system consists of LED light source (including drive), solar panel, battery, solar street light controller, street light pole and auxiliary material wire. like： ​Features and applications of solar street lights   ​The benefits of installing solar street lights in rural areas     ​Precautions ...

EMC optimized style In the application, the directional rental exhibition must run simultaneously with various electronic devices.   rental led display  ，To avoid joint electromagnetic interference, your rental monitor must be EMC-optimized. Automatic correction The rental display is innovative with "auto-correction" technology. There is absolutely no need to debug it once a client switches modules or gets a credit card. Just replace it.     Quiet operation In some high-end applications for rental displays, a low-noise follower or a fanless and low-noise potential project will be required. Sometimes, to do this, the power requirements will also be greater.     Smart Lighting Adjustment Inside the efficiency, the Brought rental exhibition around the point has only one light source, and its display effect will inevitably be affected by stage lighting such as projection, spotlight, and brain-turning lighting. Therefore, it can be required to install an au...

  1. Although the ice bucket is mainly used for ice wine, it also has a certain decorative effect,  metal ice tub ， so we can choose products of different materials and shapes according to our own preferences and needs. 2. Many people do not have a good grasp of the capacity of the ice bucket. When purchasing, we can judge the required capacity according to our usual drinking habits. It is generally guaranteed that the ice bucket can hold a quarter of the wine bottle after putting ice and water in it. about three. 3. Pay attention to the relevant information of the product, and carefully check whether the product name, material, specification, origin, manufacturer information, hygiene standards, etc. are marked on the packaging, so as to avoid choosing unhygienic products.    like： What are the options for buying an ice bucket?

The LED lamp bead is the same as the wick in the patch, but the angle of the lamp bead can be made very small, and its light is concentrated far away, but the irradiation range is limited.   led bulb components ，The angle of the patch is generally larger, the light is scattered, and the shot is relatively close, but the irradiation range is relatively wide. The power of the lamp bead is large, and the power of the patch is small. High-power LED lights generally use 1W high-power LED lamp beads, and low-power LED lights generally use SMD. Cooling is different. The patch only needs to use the ordinary circuit board, and the natural heat dissipation can achieve a good heat dissipation effect, while the LED lamp bead needs to be equipped with an aluminum heat sink. like： What are the functions of LED lamp beads The working principle of LED lamp beads The difference between the benefits of led lamp beads and patches

You can continue to smoke. After the e-cigarette is dropped in the water and dried, it can be used normally.    electronic tobacconist  ， Generally, the taste of the e-cigarette will definitely be different after drying, so it is not recommended to continue smoking. If you don’t mind, you can still use it. Electronic cigarettes are mainly composed of four parts, e-liquid (including nicotine, essence, solvent propylene glycol, etc.), heating system, power supply and filter tip. Through heating and atomization, aerosols with specific odors are generated for smokers to use. In a broad sense, electronic cigarettes refer to electronic nicotine delivery systems, including electronic cigarettes, hookahs, hookah pens and other forms. In a narrow sense, electronic cigarettes refer to portable electronic cigarettes that are similar in appearance to cigarettes. Generally, electronic cigarettes are mainly composed of three parts: a pipe containing nicotine solution, an evaporation de...
