LED power supply in the domestic power market in the status of more and more important, various types of LED module power supply products for the R & D designers to facilitate the same time, LED power quality of the situation has gradually become the engineers feel a headache for one of the problems The So how should you choose high-quality LED products? Here we introduce some of the more practical selection of skills.
Here you need to remind the engineers are in the purchase of LED module power to choose the brand hard, after the authority of the quality of qualified LED supplier brand. Some well-known large enterprises at home and abroad produced by the overall quality of LED power products are very good, although the price may be more than some small manufacturers to provide some of the products expensive, but the saying goes, a penny, the manufacturers produced by the big Related product information marked accurate, after-sales service in place, cost-effective, can fundamentally guarantee the design of the program safe and stable operation.
The second parameter to be noted is the initial luminous efficiency. In the purchase of related power products, should pay attention to the initial product value on the packaging, the product of the initial value of the higher luminous efficiency, indicating the better energy efficiency. At present, some of the better domestic LED power supply value of the initial light can already reach 100lm / W or more.
Driving capability is also one of the important parameters of the LED module power supply, in the selection of products need to pay special attention. In the process of product selection, if it is related to the problem of LED driver, you can consult the business on the various parameters, such as output voltage and current, power factor, operating temperature and so on. Generally speaking, 1W LED lamp beads operating voltage of about 3.2V, the working current is about 320mA. If the current is too large, it is easy to make lamp beads decline, shorten life. If the drive power factor is too low, such as 0.6 power factor, 10W lamp will consume 16W of power. At the same time the power factor is too low, naturally lead to drive itself to increase heat, and electronic components are most afraid of being heated, and heating means that the electronic components of their own temperature, prone to quality problems.
In the selection of LED products is the third need to pay attention to the parameters, is the product of thermal performance. LED light source is cold light source, but the chip will produce a lot of heat inside. In the purchase, should observe the appearance of the shell, smooth and smooth can be preferred. Also observe whether the heat sink has a corresponding thickness and surface area, because the heat is mainly scattered from the heat sink.
The above is this article for the LED power supply in the quality and selection, to provide some of the purchase recommendations, hoping to help engineers and designers in the LED module power selection process to find the most appropriate models.
