LED knowledge sharing: nine ways to teach you choose LED corn light
For the LED market, and the corresponding products is also very much, as consumers, how to calm the choice of LED corn light, become the consumer must know the common sense.How to scientific to choose the best cost-effective LED corn light, give you a detailed account of 9 LED under the basic performance.
1, brightness
The brightness of the LED corn light 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 of LED corn light, long life, so price is high. Antistatic usually greater than 700 v LED can be used for the LED corn light.
3, wavelength,
Consistent LED corn light wavelength, the color is consistent, if request the same color, the price is high.Not the manufacturer of the LED light color separation instrument is not easy to produce pure color products.
4, the 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 corn light, the light 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 corn lamp lights for chip, different chip, price difference is very big.Chip is more expensive, Japan, the United States generally chips in Taiwan and domestic price is lower than the day, the United States.
8, size
The size of the chip to side, said big chip LED quality is better than that of the small chips.The price is proportional with the chip size.
9, colloid
Ordinary LED corn light colloid generally for epoxy resin, with uv resistance and fire retardant LED corn light price is more expensive, high quality outdoor LED lighting should be uv and fire prevention.Each product can have different design, different design suitable for different purposes, the reliability of the LED corn light 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 corn lamp is the new products, China's 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 corn light, LED corn light don't keen on gaining petty advantages to choose have peculiar smell, is now only a few several LED manufacturer is using 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.Look from the applicable environmental security, have reliable dustproof moistureproof design, materials, fire prevention, prevent ultraviolet ray, prevent cold cracking of LED corn light price is high.
