The LED headlamp unit of choose and buy small common sense

At the beginning of the development of LED lamps and lanterns, because of the characteristics of multiple, price is higher. Whereas ordinary incandescent lamp is very cheap, ordinary people transition to accept there is a price gap. So early, mainly used for commercial, market, mostly in the streets.

with the improving of the LED technology and the widespread application, the visual senses to pursue further improve the LED lamps and lanterns, also puts forward higher requirements for product performance and product design. This needs to be updated we LED industry manufacturers, terminal product designers standard dynamic.

choose different parameter tailored 'custom' chy-tech

today, all aspects of the society have been involved in the application of LED lamps and lanterns, big to mall office, small to entertainment, whether it is from the brand concept to the product itself have also attracted popular in all walks of life, but due to the category of headlamp unit is various, quality is relatively good and bad are intermingled,. So, according to the different parameters of lamps and lanterns of choose a suitable for their own purposes of model has become the choose and buy are very concerned about a topic.

the commonly used parameters of LED lighting products, such as intensity, wavelength, color temperature, etc. , as a standard discern bad purpose. Here are the LED lighting products for the overwhelming majority of the purchaser on the commonly used parameters, 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/㎡) 。

flux phi lights 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.

the greater the number of lumens, luminous flux, the higher the brightness of the light.

2, wavelength wavelength LED, consistent color. Not the manufacturer of the LED light color separation instrument is not easy to produce pure color products.

3, color temperature

logo light color is the 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.

5 and

esd antistatic ability of LED, long life, so price is high. Antistatic usually greater than 700 v LED can be used in the LED lighting ( Lighting decoration) 。

6, life different quality is the key to life, life is decided by droop. Droop small, long service life.

7, design each kind of product can have different design, different design suitable for different purposes, the reliability of the LED lighting design aspects including electrical safety, fire safety, environmental safety, mechanical safety, health and safety, security, time and other factors.

8, energy label

energy label is to provide consumers with information such as energy consumption and efficiency, convenient for consumers to purchase of energy-efficient products. European Union energy sign

eu energy efficiency of the product is divided into seven, a-class products energy efficiency highest, lowest level G.

China's energy efficiency label energy efficiency label

China energy efficiency label for Chinese blue and white background color logo, five levels, each level

the meaning of level 1 products reached the international advanced level, most energy-saving, namely the lowest energy consumption;

more power saving level 2;

level 3 energy efficiency of products for Chinese market, the average level;

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) 。
