SMD, which stands for Surface Mounted Devices, means Surface Mounted Device. LED means light emitting diode, and there are many kinds of LED package shapes, one of which is SMD LED. SMD SMD helps to increase production efficiency as well as different facility applications. It is a solid state semiconductor device that converts electricity directly into light. It has a voltage of 1.9-3.2V, with the lowest voltage for red and yellow light.
Mother's Day is a day to thank mothers. The modern Mother's Day originated in the United States and is the second Sunday in May every year. Mothers usually receive gifts on this day.
The lighting in the kitchen is not only used for lighting, but also affects the convenience of cooking, so choose the right kitchen lights should pay attention to the following points:
Kitchen is a very high frequency of use in our home life, kitchen lighting is an area that we must pay attention to. So what lighting is needed in the kitchen?
International Workers' Day is also known as "May Day", is a national holiday in more than 80 countries around the world. It is celebrated on May 1 every year. It is a holiday shared by working people all over the world. In
The most important feature of LED light source is the long life, can reach 50,000 ~ 100,000 hours, a long time to monitor its light decay is impractical, therefore, this standard will predict the life of LED lighting fixtures through a method of accelerated life test.
LED light is a piece of electroluminescent semiconductor material chip, cured with silver glue or white glue to the bracket, and then connected to the chip and circuit board with silver or gold wire, surrounded by epoxy resin seal, to protect the role of the internal core, and finally install the shell.
Compared to the traditional street light life, LED lighting long lifespan is certain. But its specific life is also based on different environments, different materials, and different technologies, a variety of factors to determine its lifespan is also a combination of factors to determine.
The new down light surface mounted spot BOX have been lunched this month, there are three version: one head, two head and four head, It is made of SPCC and the surface is powder coated in black and white grit. This surface mounted decorative spot light has been designed with 350° adjustable, and use light source as GU10. it is very easy to install.
General household lighting are connected in parallel, this time the circuit to provide them with the same voltage, and any one break will not affect other appliances.
Strobe is to look at the screen of one appliance in the screen of another appliance, the screen of another appliance will have a bright line from the bottom of the screen pushed to the top and appear from the bottom again. This goes on endlessly, giving us the impression that the image is flickering.
