With all the increase in popularity of

With all the increase in popularity of LED lighting, many people are confused when it comes to choosing an LED lamp.

First we should understand that the high quality and price of lamps are decided by four components: LED chip, LED driver, Heat Sink and Personalised Circuit Board (PCB).

1 . GUIDED Chip

One of the two most important aspects of an LED lamp, chips are available in a wide range of performance standards and consequently the retail price will vary depending upon the brand of chip used by the manufacturer. While high performance lights use CREE or OSRAM; the purchase price may be a little rich for most customers. Instead, you may want to opt for a lamp using a chip from Bridgelux, Samsung or perhaps Epistar to name but three affordable, quality chips. Use of a good quality computer chip results in beautiful color, (as gauged by its color temperature plus color rendering index - CRI), as well as high luminous efficacy (a measure of how well a light origin produces visible light).

Chip measures are measured in millimeters (mil) and one millimeter equals one thousandth of an inch. Generally, the larger typically the chip the better the performance. Simply because specifications and claims by suppliers tend to be over-stated, it is prudent to compare one lamp with another by determining which components are used in the manufacture of the products in question.

A large number of manufactures use SMD LED potato chips in indoor lighting, such as SMD 2835 in LED tubes, and SMD 3014 in LED panel lights. These low power LEDs produce fewer lumens resulting in a light source that is easy on the human eye. Simply put, a lumen is a measurement of the amount of light emitted per next. High power LEDs are used in industrial lamps due to their small size and the result is a concentrated light source that does an excellent pret sur hypotheque job. Various LED high bay lamps happen to be fitted with 45x45 mil chips and are also used and packaged with a casino chips on board (COB) light source.

For your data, the numbers 2835, 3014, 3528, 5050, 5630 are the names regarding packaging process models. Another process with a very promising future is definitely the previously mentioned COB light source, where casino chips are mounted directly on the branded circuit boards (PCB) as opposed to appeared mount devices (SMD). As these mild sources have a variety of features, they have recommended you take a few minutes in order to familiarize yourself with them in order to best gratify your requirements.

As you have seen, LED wrapping is closely related to its functionality and manages a number of functions like heat dissipation, light distribution and even varying the color temperature and CRI of the chip. It is interesting to note that a chip that produces white colored light has yellow phosphor combined with it to change the original blue brightness it initially produces to bright.

2 . LED Driver

The second key component is the power system, normally referred to as the driver. It is the limiting factor in the longevity of the LED light fixture - while there is an urban myth that alleges the life span of a light is as much as 30 years; the driving force might only last 1000 to be able to 2000 hours. So ignore producer claims of 50, 000 hour of LED lamp life.

A reputable drivers, such as Meanwell, can be expected to have fifteen, 000 hours of life. Nevertheless, the cost would be 80% higher than the normal driver manfactured in China. Most manufacturers use their own driver. In these instances it is wise to ask if the capacitor comes from a reputable maker.

Another sign of the life is the warranty offered.

3. Heat Sink

LEDs can be temperature sensitive making the heat drain an important concern. Most products how to use aluminum alloy heat sink for its cost efficiency and while the requirements don't really tell us much, you will discover three items we should look at.

The. Thermal conductivity: die-cast 6063 lightweight aluminum is the most common material used. The better ones have anodized coating. B. Plethora and size of fins: the more and the bigger the better. C. Heat water line is used in some high power BROUGHT lamps.

4. Printed Circuit Table

The material used and the design of the PCB is important as it connects the particular chip to the heat sink. The PCB with low thermal conductivity results in a hot lamp. Metal and ceramic core PCBs possess a good heat transfer coefficient but most manufacturers choose fiberglass to save money.
