LED ceiling lamp which brand LED ceiling lamp purchasing skills
For indoor lighting, many people will use LED ceiling light , what skills are there when buying LED ceiling light? LED ceiling light brands are everywhere, which brand is better? Next Xiao Bian will take everyone to learn about LED days. What brand of lanterns and shopping skills. First, what brand of LED ceiling lamp 1, NVC lighting NVC Lighting was established in 1998 and is a company that mainly produces commercial lighting, outdoor lighting, light source electrical appliances and other products. After years of development, NVC Lighting has a number of production bases in the country, more than 2,000 stores, and its products are Passed the ISO9002 quality system certification, is China's largest manufacturer of energy-saving lamps. 2, Carey Cree was established in 1987 and is a major manufacturer of LED lighting and semiconductor manufacturing. Cree has strong R&D strength and has more than 2,900 international patents. Due to its leading materials technology and white light technology, LED lighting products rank among the world's leading players in terms of brightness, luminous efficiency, and longevity. 3, Op lighting Op Lighting was founded in 1996 and is a global lighting company. It has won the recognition of customers with its integrity and high quality products, among which LED lighting, energy-saving lamps and other series occupy a leading position in the market share. The company also received a number of honors such as the national model for after-sales service satisfaction products, as well as China's famous brand products. Second, LED ceiling lamp selection skill enough 1, radiator cooling method The speed of heat dissipation of the lamps affects the light failure degree and service life of the entire lamp. The LED ceiling light collectors are mainly divided into three types: integral heatsinks, single lamp bead heatsinks, and fan heat dissipation methods. One way of disposing a lamp bead is a method that most consumers recognize, and it can dissipate heat in time. 2, the radiator material In addition to looking at the heat dissipation method, we also need to look at the size and material of the heat sink, which will affect the heat dissipation of the light fixture. The thermal conductivity of the copper material is better than that of the aluminum material. General LED ceiling lamp material mostly aluminum, the best is the insert aluminum, the worst is cast aluminum. 3, look at the lamps of the transformer Transformer quality determines the life of the LED ceiling light. If the components do not understand, we can consult the merchant about the size and weight of the transformer to make a simple judgment. The simplest method is to look at the price. The quality of the transformer is good and the price is not cheap. Can buy brand products, brand manufacturers' products are still guaranteed in terms of quality. Xiao Bian summary: On the LED ceiling lamp which brand and buy skills Xiaobian introduced here, I hope that after reading this article, to provide reference and help for everyone. LED ceiling light
Our connector for 4-2 bundle conductors----JTL-2/4-300/40-900K, four leads and another two leads could be ordered according to the customers practical demand, the consumer should give clear indication of the lead kind. Splicing fittings are used for splicing or repairing conductor and ground wire of overhead transmission lines. The splices may be compression type, bolt type performed armour rods in accordance with the construction and mounting way. The compressive splices have hydraulic, explosive and notched type. The DC resistance of all splices must be less thank that of the equi-length conductor, the temperature rise of all aplices must be less thank that of the aplicing conductor. The slip strength of the compressive sleeve must be not less than 95% of the rated strength of conductor.
