Experts teach you how to choose LED fluorescent tubes
1. How to choose LED fluorescent tube power supply
The power efficiency must be greater than 85%, and the power factor must be greater than 0.9 to ensure the energy-saving effect.
The current stability should be high to ensure that the current is constant, so that the led fluorescent lamp does not flicker and protects the eyes.
Wide-voltage operation, 85V-265V, not interfered by fluctuations in the power grid, and has a wider range of use.
Using isolated drive power, short circuit, open circuit, overload protection, safe voltage drive, will not burn out the lamp beads.
The heat dissipation area of the led tube is 18% larger than that of the ordinary tube, and the heat dissipation is better. The temperature of the lamp is lower than 46 degrees, which greatly extends the service life.
Advanced light distribution technology ensures uniform light, good light transmission and no light spots.
Second, how to choose the delivery capacity of LED fluorescent tubes
Delivery guarantee: 10 production lines, with delivery guarantee.
Long service life: much longer than traditional fluorescent tubes, LED fluorescent tubes have at least 50,000 hours of life.
Easy to use: LED fluorescent tube does not need starter, easy to install.
Energy saving: LED fluorescent tubes can save at least 70%-80% of energy consumption.
Safety: LED fluorescent tubes use aluminum tubes and PC covers, which are safer than traditional fluorescent lamps, and have shock and earthquake resistance. The use of isolated power supply makes the product safer and more stable.
Environmental protection: LED fluorescent tube uses high-quality light source, fast start-up, no flicker, no noise; low heat generation, and no heat radiation; soft light color, no glare, no mercury, no gas or substances harmful to health, etc.
Product application range: It can replace traditional fluorescent lamps and be used for daily household lighting and lighting in shopping malls, office buildings, office buildings and other places.
Product quality assurance: Valid scope of quality assurance: proper storage, operation and maintenance. The quality caused by incorrect storage, installation, operation and maintenance is not covered by the guarantee.
3. How to choose LED fluorescent tube-internal structure
How to choose LED fluorescent tube: Pass ROHS environmental protection certification, export must
RoHS is a mandatory standard established by EU legislation. Its full name is "Restriction of Hazardous Substances" (Restriction of Hazardous Substances). The standard has been officially implemented on July 1, 2006, and is mainly used to standardize the material and process standards of electronic and electrical products, making it more conducive to human health and environmental protection. The purpose of this standard is to eliminate six substances including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electrical and electronic products, and emphasizes that the lead content should not exceed 0.1%.
How to choose LED fluorescent tube: high pressure resistance, environmental protection plug, safety and guarantee
How to choose LED fluorescent tube: the core part of LED tube, high efficiency 87%, high PF0.98, isolated power supply, safety guarantee. Safety materials CE, UL, stable quality
How to choose LED fluorescent tube: 105 degree electrolytic capacitor, high temperature resistance, suitable for high temperature environment, longer life
How to choose LED fluorescent tubes: long-life imported capacitors to ensure the use time
How to choose LED fluorescent tube: wide aluminum substrate (19mm), the lamp beads are arranged at a wide distance to ensure the safety of heat dissipation, and the imported lamp beads are used to ensure low LED light decay
How to choose LED fluorescent tube: Milky white PC light-expanding lampshade to ensure no light spots, uniform light, and no glare. The heat dissipation area of the led tube is 18% larger than that of the ordinary tube, and the heat dissipation is better. The temperature of the lamp is lower than 46 degrees, which greatly extends the service life.
4. Testing by authoritative institutions
Passed CE-EMC certification
Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate in compliance with the requirements in its electromagnetic environment and not produce intolerable electromagnetic interference to any device in its environment. Therefore, EMC includes two requirements: on the one hand, the electromagnetic interference generated by the equipment to the environment during normal operation cannot exceed a certain limit; on the other hand, it means that the equipment has a certain degree of electromagnetic interference in the environment. The degree of immunity, that is, electromagnetic susceptibility.
The so-called electromagnetic interference refers to any performance degradation of equipment or systems. EMC includes EMI (electromagnetic interference) and EMS (electromagnetic tolerance). The so-called EMI electromagnetic interference refers to the electromagnetic noise generated by the machine itself that is not conducive to other systems during the process of performing its due function; and EMS refers to The ability of the machine to not be affected by the surrounding electromagnetic environment in the process of performing its functions.
Passed CE-LVD certification
The LVD Directive, the Low Voltage Directive Test, was enforced on January 1, 1997. For electronic and electrical products with an input voltage exceeding 75V for DC and 50V for AC, they must comply with the European safety requirements of the Low Voltage Directive CE-LVD before they can enter the EU market. The LVD directive items include: product labeling, component requirements, temperature rise and tidal conditions, fire and flame retardant, structural strength, etc.
The CE-EN62471 certification is a test standard for laser products promulgated by the European Union. The IEC/EN60825 standard mainly focuses on energy level testing. In addition to energy requirements, IEC/EN 62471 also focuses on biological aspects, including radiation intensity and radiance. According to the measured data in IEC/EN 62471, there will be a classification for each product, including exemption level, low hazard, medium hazard, and high hazard level.
IEC/EN 62471-Guidelines for evaluating the photobiological safety of lamps and lamp systems. Particularly detailed exposure limits, reference measurement techniques, classification assessments and control of incoherent multi-frequency optical hazards of all electric drives in optical radiation, including LED products
How to choose LED fluorescent tube:
1. The luminous efficiency reaches 160LM/W, and the brightness of 160LM is produced for every 1w consumed. Only good LED lamp beads can reach this standard, which is an important energy-saving indicator. At present, the quality of 2835 lamp beads in the market is difficult to distinguish, the price is uneven, and it is not easy to choose. Using 3014 high-lumen lamp beads, it is difficult for ordinary manufacturers to make it, and there are relatively few counterfeit, and the quality is guaranteed.
2. Power factor PF=0.976, an important parameter,
Power factor is an important technical data of power system. Power factor is a coefficient that measures the efficiency of electrical equipment. The low power factor indicates that the reactive power used by the circuit for alternating magnetic field conversion is large, which reduces the utilization rate of the equipment and increases the power supply loss of the line. Therefore, the power supply department has certain standard requirements for the power factor of the electricity user.
When the user's power factor increases, the reactive power it draws from the power system will be reduced, so the voltage loss will also be reduced, thereby improving the user's voltage quality.
3. Power saving, number of lamp beads, brightness
Using 2835 high lumen lamp beads, greatly reducing the number of lamp beads.
