Double-ended LED tube is difficult to match
In recent years, fluorescent tubes have been gradually eliminated by the lighting market, and LED tubes are greatly crowded. The double-ended LED tube has a similar shape to the fluorescent tube, and is connected at both ends, so it is very convenient to replace. In the Chinese mainland market with huge infrastructure construction, the demand for double-ended LED tubes has shown a blowout situation. In recent years, fluorescent tubes have been gradually eliminated by the lighting market, and LED tubes are greatly crowded. The double-ended LED tube has a similar shape to the fluorescent tube, and is connected at both ends, so it is very convenient to replace. In the Chinese mainland market with huge infrastructure construction, the demand for double-ended LED tubes has shown a blowout situation. In addition, due to the difference in illumination principle, the fluorescent lamp is ionized by the filaments on both sides, that is, the gas is electrically conductive and emits light, and the LED is semiconductor light-emitting, which has lower conduction current, smaller terminal voltage, and better energy saving. The requirements of social sustainable development have become the only choice in the field of public lighting. However, the iterative process of technology has never been smooth, not to mention the replacement of this lighting field is not only a lot of money and manpower, but may even affect the security of the installation. Behind the bustling market of double-ended LED tubes, there are hidden dangers of electric shock during installation. It is precisely because of the lighting principle of the double-ended LED tube that the electric shock hazard is always accompanied by it. The lamp has an internal electrical connection. Most of the double-ended LED tubes are inserted into the charged lamp holder at one end, and the other end is charged by the internal circuit when it is suspended, which brings both electric shock and drop to the toucher. Many consumers will question whether the double-ended LED tube is so dangerous that it can still be popular in the market. In fact, not all LED tubes have problems. The internationally accepted IEC (International Electrotechnical Commission) standard regulates LED lamps from four aspects: electrical strength, insulation resistance, creepage distance, and contact current. The US UL1993 standard also clearly defines the other when the LED lamp is plugged into the power supply. Leakage current at one end, however, due to the fact that domestic related safety standards have not yet been introduced, the market is full of double-ended LED tubes with safety hazards. Fortunately, some of the leading companies in the lighting industry are beginning to consciously develop production and guide consumers to use safer single-ended LED tubes. Compared with double-ended LED tubes, single-ended cable entry eliminates the risk of electric shock from the other end of the installation process, while maintaining good lighting performance and energy saving features. For the replacement installation problem that people are worried about, Philips lighting after-sales engineers said that if it is newly renovated, it can be inserted directly into the installation. If you replace the original fluorescent tube, you need to re-route, for a qualified electrician, wiring is very simple.
