This version uses a powerful high-frequency switching transistor (BD139), and powerful transistors can enhance the effect. The so-called "the stronger the responsibility, the greater the responsibility."
TOP9: Intelligent lighting, the trend of forward-looking LED low price to kill
The incandescent lamp ban in major countries and regions in the world entered the batch effective phase in 2014. On January 1, 2014, the United States announced that it would no longer produce and sell 60-watt and 40-watt incandescent lamps. At the same time, Canada also officially banned 75 watts. And 100 watt incandescent lamps. The EU completely banned the sale of incandescent lamps in 2012. Coupled with the decline in the cost of LED lighting, it will certainly trigger the outbreak of the LED general lighting market.
TOP10: Intelligent control LED bulb Hue dismantling: the smartest intelligent lighting, how to do Philips?
We got Hue the last two days, we broke down one for the first time, because we want to know inside, a traditional lighting company, the old antique company that pays attention to the basic technology accumulation, how to put down the shelf to be a traditional Taiwan factory. The small peripherals that will be concerned, the bleak sales of Belkin's Wemo series is not enough to give the big brother a lesson?
TOP11: Circuit diagram reading every day (28): Design of circuit module for wireless LED lighting power supply system
Wireless power supply is a new technology that is convenient and safe. Without any physical connection, power can be transmitted to the load at close proximity without contact.

At present, with the advancement and innovation of LED light source, the brightness and luminous efficiency of LED products are continuously increasing, and the cost is decreasing. LED light sources are more and more used for illumination to replace traditional light source illumination. Therefore, in the face of constant changes in LED technology, some organizations in Europe and the United States have proposed new standards or regulations for LED lamps (modules) and lamps. Countries have put forward many requirements for energy efficiency testing of LED lamps and lamps.
TOP18: The connotation of LED lamp design, product interpretation of well-known enterprises
Incandescent lamps have not changed much in more than a hundred years, but the emerging LED bulbs are experimenting with different shapes and operating principles, making LED-based retrofit lamps still the hottest in the solid-state lighting (SSL) industry. One of the topics, especially in 2012 and the first half of 2013, is to introduce some pioneers. Although the shapes and sizes of various lamps are different, they are based on the inherent advantages of LED light sources, and the energy-saving advantages are attractive. Globally, LED bulbs are enthusiasm for manufacturers because they are suitable for a large number of original incandescent sockets. Because its basic size and type of socket are fixed, manufacturers are taking a completely different approach, trying to win this potentially short-lived market.
TOP19: Demystifying LED flip-chip technology you don't know
LED itself has a huge product advantage and a good future development prospects for the industry. This is a fact that has been widely recognized and will not be repeated here. We focus on the current state of the industry. To be exact, in the past 10 years, LEDs have not been popular in the Chinese market! LED lamps do save energy, but they are 5-8 times higher than energy-saving lamps. Users always use the intersections that are not used. However, with the advancement of technology, the reduction of costs and the drive of national policies, this situation has now improved. LED lamps are gradually entering our daily life, from LED street lights, LED decorative lights, LED table lamps and other market sales prices, sales. We can see one or two.
