With the development of the market, as a consumer, choose LED is still should to be calm, scientific analysis, choose the best cost-effective light source and lamps and lanterns, the following introduce the basic performance of several kinds of LED:
1、Luminance：the Luminance of LED is different, the price is different.Used for LED lamps and lanterns, the LED should comply with the laser level Ⅰ class standard.
2、Antistatic ability：Antistatic ability powerful to LED , long life and therefore price is high. usually Antistatic of the LED greater than 700 v can be used in the LED lighting.
3、Wavelength：the same Wavelength of LED, the same color, such as request the same color, so the price is high.if without the LED spectrometer and Color separation instrument of the manufacturer , it is difficult to produce pure 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 of LED, short service life, low price
5、Irritation angle:different uses of LED’s Irritation angle,the LED’s Irritation Angle is different.Special light Angle, the price is higher.Such as the diffuse Angle, the price is higher.
6、Life: different quality is the key to 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 of Japan and the United States is more expensive,Generally speaking,the chips in Taiwan and in domestic the price is lower than Japan and the United States.
8、The size of the chip shows, big chip of LED’s quality is better than that small chips.The price is proportional with the chip size.
9、Colloid ordinary’s LED colloid generally for epoxy resin, leds with uv radiation and fire retardant added more expensive, high quality outdoor LED lighting should be resistance uv and fire prevention.Each product can 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.observe from the perspective of the electrical safety shall comply with the relevant international standards.
Because of the LED is a new product, the china national standard is lag, but countries to provide product qualification testing.With international safety certification (such as GS, CE, UL, etc.) and countries product quality certificate of the LED lamp and the price is higher, because these products on the safety design is reliable.The attention of consumers is to carefully identify certificate of authenticity, now there is no many factories have the international safety certification and the national product certification
seen 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 to choose smell LED lighting ，Currently only a small number of LED manufacturers is to use non-toxic materials production,the method of Identify can use nose Identify directly,prices of Smelly products are more lower than without bad smell。Similar such as lead, mercury， cadmium and so on toxins, needs professionals analysis.see from the applicable environmental security, have reliable dustproof moistureproof design, materials fire prevention, prevent ultraviolet ray, prevent cold cracking of LED products price is high.
