1. There is mercury pollution in the production process of energy-saving lamps and after use. At present, Western countries pay considerable attention to mercury pollution. Chinese people are also increasingly aware of the dangers of mercury pollution. The led lamp is environmentally friendly and has no harmful substances such as mercury. The assembly parts of the LED lamp can be easily disassembled and assembled, and can be recycled by others without recycling by the manufacturer.
2, energy-saving lamps are glass products, easy to break, not good transportation, not easy to install. Led lamp solid state package, belonging to the type of cold light source. Therefore, it is very convenient to transport and install, can be installed in any miniature and closed equipment, is not afraid of vibration, basically does not need to consider heat dissipation.
3, the energy consumption of energy-saving lamps is still a bit too big. White LEDs consume only 1/10 of the energy of incandescent lamps and 1/4 of energy-saving lamps.
4, energy-saving lamps are easy to damage, short life. Led lamp longevity, life expectancy of more than 100,000 hours, can work at high speed. If the energy-saving lamp starts or turns off the filament frequently, it will turn black and quickly break.
5, a single LED power is low, in order to achieve the same brightness as the energy-saving lamps need to be used in parallel.
6, the color rendering index is low, the color displayed under the LED illumination is not true.
7, LED lighting technology is not as mature and perfect as energy-saving lamp technology. In addition, at present, led is more expensive than energy-saving lamps.
Comparison of energy-saving lamps and ordinary bulbs
Energy-saving comparison: Generally speaking, in the case of the same wattage, the energy-saving lamp is 80% more energy-efficient than the ordinary bulb, and the energy-saving lamp consumes 57% less than the ordinary bulb. The energy-saving lamp of 5 watts is about 25 watts. The brightness of a normal light bulb, the 7-watt energy-saving lamp is about equal to the brightness of a 40-watt ordinary light bulb, and the 9-watt energy-saving light is about equal to the brightness of a 60-watt ordinary light bulb. It can be seen that energy-saving lamps are more energy efficient than ordinary white woven lamps.
Comparison of principles: Energy-saving lamps operate on the principle of gas discharge, that is, self-ballasted fluorescent lamps. The energy radiation of energy-saving lamps is only 20%. The ordinary bulb is the heat generated when the current passes through the filament. The filament continuously collects the heat, so that the filament temperature reaches 2000 degrees Celsius or higher. The higher the filament temperature, the brighter the light is. When a normal light bulb emits light, a large amount of electrical energy is converted into heat, and very little is converted into useful light energy. Since the electro-optical conversion efficiency is low, the heat is first generated and then the light is emitted, so that infrared radiation is generated.
Health comparison: Energy-saving lamps can effectively eliminate formaldehyde and dirt. At the same time, the released active oxygen can adsorb and kill various viruses and bacteria such as Escherichia coli. Energy-saving lamps can also change the air quality of the living room, and the manufacturing process is advanced, the performance is high, and the service life is six times that of ordinary incandescent lamps.
Life comparison: The life of ordinary fluorescent lamps mainly depends on the tungsten wire. The faster the tungsten is sublimated, the shorter the service life of ordinary fluorescent lamps, and the energy-saving lamps rely on the gas and the luminescent materials coated on the pipe wall to work. The luminous efficiency is higher than that of tungsten. More durable, therefore, energy-saving lamps have a longer life than ordinary bulbs. Normal bulbs typically have a life of 2,500-3,500 hours, a national standard life of 1000 hours, and energy-saving lamps of up to 50,000 hours.

High Frequency PCB
High frequency PCB also called HF PCB.The RF frequency range is typically from 500 MHz to 2 GHz, and designs above 100 MHz are considered RF. The microwave frequency range is anything above 2 GHz. There`s a considerable difference between RF and microwave circuits versus typical digital and analog circuits. In essence, RF signals are very high frequency analog signals. Therefore, unlike digital, at any point in time an RF signal can be at any voltage and current level between minimum and maximum limits. We have much experience in this filed,up to 60 GHz PCB we made.
