At present, incandescent lamps are facing a phase-out situation. Energy-saving lamps and LED lamps have become mainstream in the market. Then, led energy saving lamps do good or better? How about the price of energy-saving lamps and LED lamps? Let's take a look with Xiaobian.

Led or good energy-saving lamps - Introduction of energy-saving lamps and LED lights
1. The official full name of the energy-saving lamp is a rare-earth trichromatic compact fluorescent lamp, which has the advantages of high luminous efficiency, obvious energy-saving effect, long service life, small size, and convenient use. Its working principle and fluorescent lamps are basically the same. In addition to white (cold light), energy-saving lamps now have blue (warm light). Generally speaking, under the same wattage, an energy-saving lamp can save 80% energy compared with incandescent lamps, with an average life expectancy of 8 times, and thermal radiation of only 20%. Under non-strict conditions, a five-watt energy saving light can be regarded as an incandescent lamp equal to 25 watts. A seven-watt energy-saving light equates to about 40 watts, and a nine watts equates to about 60 watts. Philips, which was born in the Netherlands in the 1970s, refers to a lighting device that combines a fluorescent lamp with a ballast or ballast as a whole. The size of the energy-saving lamp is similar to that of an incandescent lamp, and the interface with the lamp socket is also the same as that of the incandescent lamp. Therefore, the incandescent lamp can be directly replaced. 80% of the energy-saving lamps in China are produced in Guangdong, and 80% of them are produced in ancient town of Zhongshan. This kind of light source can only consume 1/5 to 1/4 of the power of an ordinary incandescent lamp under the premise of achieving the same output of light energy, which can save a lot of lighting power and costs, and is therefore called an energy-saving lamp.
2, LED lights, also known as light-emitting diodes, it is a solid-state semiconductor device that can directly convert electricity into light. The heart of the LED is a semiconductor wafer. One end of the wafer is attached to a support, one end is negative, and the other end is connected to the positive electrode of the power supply, so that the entire wafer is encapsulated with epoxy resin. The semiconductor wafer consists of three parts, one part is a P-type semiconductor, in which holes are dominant, and the other end is an N-type semiconductor, which is mainly electrons on this side, and usually has 1 to 5 cycles of quantum wells in the middle. When current is applied to the wafer through the wire, electrons and holes are pushed into the vector well. In the quantum well, electrons recombine with holes, and then they emit energy in the form of photons. This is the principle of LED light emission.

Led or good energy-saving lamps - Comparison of the advantages and disadvantages of energy-saving lamps and LED lights
The advantages and disadvantages of energy-saving lamps
First, the advantages of energy-saving lamps:
The energy conversion rate of energy-saving lamps is much higher than that of incandescent lamps, which saves energy. It can also be said to reduce the emission of greenhouse gases and has a long service life.
Second, the shortcomings of energy-saving lamps:
1, energy-saving lamps start slowly.
2, energy-saving lamps are bright line spectrum, so the usual energy-saving lamps are purple light, see things under the energy-saving lamps will be severely discolored. Blue will turn purple, red and yellow will look more vivid. Therefore, energy-saving lamps should not be used in color matching workplaces.
3. After a long-term investigation and research, the scientists have reached a preliminary conclusion: The radiation of energy-saving lamps may pose a danger to human health and even cause cancer.

The advantages and disadvantages of LED lights
First, the advantages of LED lights
1. High-energy-saving: Energy-saving energy is pollution-free. DC drive, ultra-low-power electro-optic power conversion close to 100%, the same lighting effect than traditional light sources energy saving more than 80%.
2, long life: LED light source it is called longevity lamp, which means never go out of light. Solid cold light source, epoxy resin encapsulation, there is no loose part of the lamp body, there is no weakness of the filament luminescence, heat deposition, light decay, etc., the service life of up to 60,000 to 100,000 hours, 10 times longer than the traditional light source life the above.
3, changeable: LED light source can use the principle of three primary colors of red, green and blue, under the control of computer technology so that three colors with 256 gray levels and arbitrary mixing, can produce 256 × 256 × 256 = 16777216 colors, forming The combination of different light colors is varied to achieve a variety of dynamic effects and various images.
4, Lee environmental protection: environmental protection is better, there is no ultraviolet and infrared light in the spectrum, there is no heat, no radiation, little glare, and waste can be recycled, no pollution does not contain mercury elements, cold light source, can be safely touch, is typical Green lighting source.
5, high-tech tip: Compared with the monotonous luminous effect of traditional light sources, LED light source is low-voltage microelectronics products, successfully integrated computer technology, network communications technology, image processing technology, embedded control technology, it is also digital information products , Is a semiconductor optical device "high-tech tip" technology, with online programming, unlimited upgrades, flexible features.
Disadvantages of LED lights:
1, LED lights can not completely replace incandescent lamps; luminous flux, light efficiency and color rendering can be, but it is too expensive and will not decline in recent years. However, the cost of replacing incandescent lamps can be reduced by increasing the luminous flux of the product.
2, LED can not be used as a simple light source; its use to drive power, optical and thermal conduction.
3, LED lights will also heat, need to heat.

Bottle Trap
We all tend to see and choose the most beautiful basins and taps for our bathrooms, but never notice that bottle trap, a basin accessory that does so much more than just making the bathroom look great. Bottle trap connect to basin waste, accumulating used water and other waste and dirt, preventing those foul smells from drainage pipe. It has bottle trap, P trap, or S bend.
