How to LED lighting lamps and lanterns of choose and buy should pay attention to the eight parameters

Editor's note: when consumer is buying the LED lighting lamps and lanterns, it is necessary to understand some commonly used parameters of LED lighting products, such as intensity, wavelength, color temperature, etc. , as a standard to identify strengths and weaknesses. Below small make up for the majority of consumers about the commonly used parameters of LED lighting products and tell you how to buy LED lighting products. 1, the brightness of LED lamp brightness including: brightness L: light in a particular direction unit solid Angle of the luminous flux per unit area. Unit: take off ( cd/㎡） 。 Luminous flux phi: light the sum total of the amount of light emitted per second. Unit: lumen ( Lm） , said lights shine, shine the more the greater the number of lumens. Is: the greater the number of lumens, luminous flux, the higher the brightness of the light. 2, consistent LED wavelength wavelength, the same color. Not the manufacturer of the LED light color separation instrument is not easy to produce pure color products. 3 logo light color is the color temperature, color temperature measuring unit, said with K values. Yellow light is below 3300 k, the white light is 'more than 5300 k, and the middle color' k - 3300 5300k”。 Customers can according to individual be fond of, application environment and the need to create an atmosphere of lighting effects and choose appropriate color temperature of light source. 4, the leakage current of LED is a one-way conductive lights, if there is a reverse current, is called the leakage, leakage current big LED, short service life. Antistatic ability of LED 5, antistatic ability, long service life, thus higher prices. Antistatic usually greater than 700 v LED can be used in the LED lighting ( Lighting decoration) 。 6, different life quality is the key to life, life is decided by droop. Droop small, long service life. 7, design, each product will have different design, different design suitable for different purposes, the reliability of the LED lighting design aspects include: electrical safety, fire safety, environmental safety, mechanical safety, health and safety, security, time and other factors. 8, energy is to provide consumers with an identifier with energy information such as energy consumption and efficiency, convenient consumers purchase of energy-efficient products. Eu energy marks the eu energy efficiency of the product is divided into seven, a-class products energy efficiency highest, lowest level G. Energy efficiency in China's energy efficiency label marked as blue and white background color logo, five levels, each level: the meaning of grade 1: products reached the international advanced level, most energy-saving, namely the lowest energy consumption; Level 2: to compare the energy-saving; Level 3: product energy efficiency as the average level of our country's market; Level 4: product energy efficiency is lower than the market average; Level 5: market access standards ( Below the level requirements do not allow the production and sales of the products) 。
