LED light guide

Introduction: LED lamp price gap so large: LED lamps compared to incandescent lamp, fluorescent lamp has the advantage of energy saving, environmental protection, long life, more and more in the market by consumers at the same time, the production of LED lighting manufacturers more and more, the competition is very fierce. The so-called experts see road, lay watch the fun, so consumers can only through the lamp appearance, structure, appearance and specifications to identify products, the above features, the structure is almost the same as the product price is two or three times or more, really makes people confused.

Where is the real reason for the big difference:

1, the service life

Life is the key to the LED lamp quality, mainly affected by light, low light decay, long service life, long service life, high price. In addition, antistatic ability will also affect the service life, anti-static ability is stronger, longer service life.

2, brightness

The main purpose of our choice is to illuminate the lighting, so the impact of price on the brightness of the crucial.

3, chip

Chip is the core of the LED lamps, can not shine on it. Different chips, the price gap is very large, the United States, Japan imported chips more expensive, Taiwan and the mainland LED chip prices cheaper. At the same time, the size of the chip is also very important, the general quality of the LED chips are better than small chips, chip size and price.

4, shell

LED lamp in the use of the process, will produce a lot of heat, the heat is mainly distributed through the shell, to ensure the normal use of lamps. So a good fixture will make the price difference.

5, drive power

Drive power is equivalent to the heart of the LED lamps, the power supply is good or bad affect the lamp life, brightness, etc..

6, the wavelength of light

Wavelength consistent LED, pure color, the price is relatively high. The general use of LED spectrophotometer to determine.

7, light angle

Many places need to use a specific lighting angle of the LED lamp, the price of this lamp is generally high. Diffuse angle.

Combined with the above points, at the same time as far as possible to choose those who have a good reputation, quality assurance, or have a perfect LED lamps testing equipment manufacturers better.
