Teach you how to choose led lamps

In the current home improvement market, the price is too high, and it is full of fakes, which is actually damaging the interests of customers. The led industry has begun to rise in China, incandescent lamps have withdrawn from the market, and the national energy conservation and emission reduction policies have supported The days of led flourish sub-cakes are also coming.

Now go to the lighting shop to buy a lamp, pick the led light source, the price is generally more expensive than the energy-saving lamp, but it is more cost-effective. This is the first, power saving, can save a lot, I believe that the details page of Taobao sellers have been displayed; this second, long life, the life expectancy is about 5 more than the energy-saving lamps; this third, worry , a lamp to buy back, old and bad, trouble, energy-saving lamps are not lamps or ballasts, trouble

However, the LED market is booming, and the Chinese people are following the trend. The emerging industries can all get a piece of food, so no matter what is good or bad, it is king to sell it! This is the heart of the businessman.

Led, nothing more than three big blocks: drive, heat, chip

First: drive

The current LED market driver is nothing more than three kinds: plastic shell; car shell; aluminum shell. Of course, the grade is recursive.

Three kinds of pictures are uploaded (just find a few pictures, you can know)

Molded case led power supply

Car shell led power supply

Aluminum shell led power supply

Aluminum shell

Molded shell, the whole lamp is added together, it is 6 yuan, but everyone is willing to sell this, I sell a dozen dollars, earning happiness, but the driving work of this kind is really bad. Can't describe it, even the PCB board is the worst and the worst, so it is recommended not to buy this when you buy it.

The kind of car shell is of course better than the plastic case. It seems to be a little grade. This kind of thing can be used, and it does not have much harm. The quality is still considered, the price of the retail is generally more than 10 to 20

Of course, the aluminum shell is the best on the market. Where is it? Heat dissipation, the drive is also to dissipate heat, after all, the electronic device inside, the temperature is high, there will be problems. And the plastic case can't talk about any heat problem.

The driver is looking at it. When you buy it in a physical store, you may want to let the store open it. It’s not a matter of the inside. It’s nothing to compare.

Second: heat dissipation

Generally speaking, the heat dissipation is about the heat dissipation of the heat sink: it is the big butt behind the lamp. The current spotlights on the market are generally divided into two kinds of radiators: the sun flower radiator; the blade radiator

Drawings:

Blade radiator

In this case, the blade heatsink is definitely better than the sun flower radiator. Not from other perspectives, it is not the same in terms of weight. As the name suggests, the radiator is to dissipate heat. Some merchants say that the blade is better, but it is wasteful, unnecessary, and expensive. In fact, the process is slowly improved, the blade heatsink can be made, not because it is heavy, it is a waste, an LED chip , the heat dissipation is amazing, it will be hot after lighting for a while, in order to protect the chip, so the heat The device is important.

Third: chip

Now the business will say where is my chip imported. This is really a fool! Because of the chip, the Chinese still can't make it. The high-end technology of LED is still controlled by foreigners. The Chinese can only import chips and then package them! If the package is also abroad, then you can brag! Of course, there are still differences in the manufacturers of chips. The US Curry and Taiwan's wafers are very good in the industry, and Taiwan's Guanghong will be almost inferior. Of course, if you engage in a sharp chip and then use the domestic rough package to do it, it is impossible. It is like the assembly of the engine of Ferrari to QQ. This is unrealistic and the market is not allowed. Of course, we generally can't distinguish between his good and bad. What is the good and bad of the good chip and the bad chip? The light fades! The led light is on when it is on, but it will not light up after a long time. The difference is here. Poor, life may be long, but not bright, what do you want it to do, right?

Of course, there are many other details: the quality of the connecting line, the thickness of the face ring, the material, etc. will affect the quality of a light. In short, this market is too hydrated, and parents must ask more and more when purchasing. But a blade heatsink/aluminum shell drive is there, and this product is no worse.

Non-Shielded Control Cable YY CVV LIYY

Low Voltage Control Cables

When setting up an electrical system, choosing the right Control Cable is key for guaranteeing steady and reliable signal communication. In the realm of non-shielded options, three types rise to prominence for their specific benefits: Yy, Cvv, and Liyy.

Here's a thorough walkthrough to help you select the right non-shielded control cable for your operations.

Understanding Non-Shielded Control Cable Yy for Stable ConditionsThe "Non-Shielded Control Cable Yy," also referred to as YSLY or HSLH, is a staple in the industry due to its adaptability. It comprises finely stranded copper conductors coated in PVC, while its PVC outer layer offers basic defense against common environmental factors. It's well-suited for dry conditions where the demand for mechanical durability is low. Some applications for Non-Shielded Control Cable Yy include building automation, signal relay in industrial control systems, and home appliance wiring.

Non-Shielded Control Cable Cvv: Tailored for Dynamic InstallationsThe "Non-Shielded Control Cable Cvv" variant, known as well as YSLYV or HSLVY, steps up in terms of flexibility, thanks to an additional layer of tinned copper braid. This not only heightens mechanical protection but also aids in managing cable placement within dynamic settings. The Cvv cable is a choice selection for installations requiring regular movement, as found in machinery connections and temporary control units in environments that remain dry and undisturbed by harsh outdoor elements.
Non-Shielded Control Cable Liyy: Combining Flexibility with EMI DefenseFor locations experiencing moderate electromagnetic interference, the "Non-Shielded Control Cable Liyy," identifiable as YSLYCHY or HFLHCH, is designed to withstand such challenges. With an added braided shield of tinned copper, it goes beyond the Yy and Cvv's offerings by safeguarding signal integrity amidst EMI. Despite the additional protection, Non-Shielded Control Cable Liyy maintains considerable flexibility and is ideal for a variety of applications, including industrial plants where EMI is present and in building facilities where mild electrical noise is a factor.
Conclusive Thoughts on Choosing Your Non-Shielded Control CableThe decision on which non-shielded control cable - Yy, Cvv, or Liyy - to use, should be informed by:
The environmental conditions: moisture, stress, and EMI presence.
The degree of cable flexibility required during installation and use.
The specific role the cable will fulfill in the control system.
Adherence to safety and operational standards set within the industry.
With a clear comprehension of Non-Shielded Control Cable Yy, Cvv, and Liyy characteristics, your choice will be sound, ensuring a robust and reliable infrastructure for your electrical controls.
