What is the package of LED?
An LED package is a plastic casing that carries an LED chip and phosphor. The LED chip is the semiconductor material that emits light (blue light) and the phosphor material converts some of this light into green and red wavelengths. This mixture results in the white light that is emitted by the LED package.
Which is better COB or SMD LED?
Although a COB LED is efficient, an SMD LED has an even greater level of efficiency. That’s because more lumens are produced per watt. In other words, you’ll receive more light with less wattage. An SMD LED also produces a broader light beam, which means the light doesn’t need as large of a heat sink as a COB LED does.
What sizes do LEDs come in?
Types of LED These are available in different shapes and sizes and the most common ones being 3mm, 5mm and 8mm LEDs. These LEDs are available in different colors like Red, Blue, Yellow, Green, White, etc.
Are 3030 LED chips good?
It not only produces the highest light output but also has the best flux performance. The 3030 SMD can be driven by a large current, and can effectively dissipate heat. These LED Chips can work under various environmental conditions and are suitable for industrial and commercial lighting applications.
How do I know what size LED lights to buy?
When buying LED strip lights, you need to measure the total perimeter of your room, including any alcoves or sections of walls that stick out. Then buy strip lights that are either the perfect length or, more likely, longer than you need – you can cut them to length.
What size are LED strips?
An LED light strip is usually 3/8 inches in width (10mm). However depending on the manufacturer or brand, widths can range from as narrow as 5/16″ (8mm) to just short of 1/2″ (12mm) sizes.
Whats the difference between LM301B and LM301H?
According to the data sheet, the LM301H LED has the same electrical and optical characteristics as the LM301B variant. It is available in different colour temperatures from 2200K to 6500K and in colour rendering index CRI 70-90. Another variant with the designation LM301H One is now also available.
