LED Light DC Drive

LED Light DC drive

With the LED lighting market hot sales, as consumers, choose to be calm, scientific analysis, selection of the best cost-effective LED flood light source, the following describes several basic performance:

1, LED floodlight brightness is different, the price is different. For the lamp should be consistent with the laser class Ⅰ class scale.

2, anti-static ability, long life, and thus high prices.

3, the same wavelength, the same color, such as the requirements of the same color, the price is high

4, leakage current is a one-way conductive light, if there is reverse current, then called leakage, leakage current, life is short, low prices.

5, the use of different angles of light its different angle of light. Special light angle, the price is higher.

6, life of different quality of the hub is the life, life by the decay of light. Light fades small, long life, long life, high prices.

7, the wafer of the luminous body for the wafer, different chips, the price difference is very large. Japan, the United States of the chip more expensive, generally Taiwan and domestic chip prices lower than Japan, the United States.

8, the chip size of the chip size to side length, large chip quality is better than the small chip. The price is proportional to the size of the chip.

I believe that many people have heard of LED lamps, LED eye protection, LED lights, LED bulbs, etc., we all know that the current child's learning pressure, more operations, resulting in children every day in the day under the lamp to write homework, reading The time is generally more than 2-3 hours, and even parents for the child's visual health will choose LED eye protection lamp to the children, but the survey found that many parents of LED knowledge is not very understanding, do not know what the details of LED thing.

 A: The concept of LED

What is the LED? LED concept is still relatively simple, LED refers to LED = Light Emitting

Diode is a solid-state semiconductor device capable of converting electrical energy into visible light.

LED has a lot of other traditional light source can not be compared to the upper hand, it was thought to replace incandescent and fluorescent lamps have the potential of the 21st century green light source. Two: LED strengths

(1) high energy saving

Energy efficient. DC drive, ultra-low power (single tube 0.03-0.06 watts) electro-optical power conversion close to 100%, the same lighting than the traditional light source more than 80% energy saving.

(2) long life

Ordinary lamp life of about a few thousand hours, and LED light source it is called longevity lamp because the LED is a solid cold light source, epoxy resin package, strong, chaos, impact. Life of up to 60,000 to 100,000 hours, more than 10 times longer than the traditional light source life.
