Lighting electricity consumption accounts for 19% of the world's total electricity consumption, and 83% of lighting power comes from the commercial building and outdoor lighting, thus derived a lot of lighting energy saving technology, the LED light source technology is a kind of is characteristic. LED by the display lighting and lighting is not just two years time, led tube manufacturer, led tube supplier, media together, LED lighting in situations where there is no recognized brand, price war started ahead of time. Products are almost the same appearance, structure, function, price difference is 2 to 3 times, many users get faint head, I don't know spreads to come from, choose what price of products.
LED light-emitting diodes and chip
Now have the ability to the production of LED and LED lighting manufacturers are few, different manufacturers choose different quality of LED is the important cause of LED lamp is acted the role of the price is different. Red LED, for example, general use of ordinary red LED the price between 0.03 to 0.08 yuan, and is suitable for production of LED lighting red LED the price between 0.12 to 0.36, higher quality more than 3.2 yuan/only, is generally not in the production of LED tube LED lighting manufacturers are difficult to separate, and consumers. So, choose their production of LED light-emitting diodes, or own a perfect LED testing equipment of LED lighting factory products better guaranteed.
(1) Brightness: the brightness of the LED is not the same, the price is not the same.
(2) Antistatic ability: antistatic ability of LED, long life, so price is high. Antistatic usually greater than 700 v LED can be used in the LED lighting.
(3) Wavelength, wavelength of LED, same color, the price is high. No LED light color separation instrument manufacturers of basic cannot produce color products.
(4) Leakage current: LED is a one-way conductive lights, if there is a reverse current, is called the leakage, leakage current big LED, short service life, low price.
(5) Light Angle: use different LED light Angle is different, special light Angle, the price is higher.
(6) Different quality is the key to life: life, life is decided by droop. Droop small, long service life, long life, high price.
(7) Chip: LED lights for chip, different chip, price difference is very big. Chip prices are higher, Japan, the United States generally Taiwan and mainland China production of chip price is lower than the day, the United States.
(8) Chip size: the size of the chip to side, said big LED chip quality is better than that of the small chips. The price is proportional with the chip size.
(9) Colloid: ordinary LED colloid generally for epoxy resin, leds with uv radiation and fire retardant added more expensive, high quality outdoor LED lighting should be uv and fire prevention.
LED lighting design reliability is different, the price is different
Each product can have 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.
From the perspective of the electrical safety shall comply with relevant international and national standards. Because of the LED is a new product, the national standard lag, but countries to provide product qualification testing. With international safety certification (such as GS, CE, UL, etc.) and the national product quality certification of the LED lamp price is higher, because these products on the safety design is reliable. The attention of consumers is to carefully identify certificate of authenticity, now has the international safety certification and the national product certification factory is not much. From the aspects of health, the use of non-toxic materials, design of the product price is higher, especially the indoor LED lighting, don't keen on gaining petty advantages chooses is faulty LED lamp act the role ofing, currently only a small number of LED manufacturers is to use non-toxic materials production, to identify the method can directly use the nose, smelly products price more lower than without bad smell. Similar toxins such as lead, mercury, cadmium needs professional analysis.
