Unlocking the Secrets of LED Bulbs: From Production to Performance, Appearance, and Components

Filament LED Bulbs

When I was a child, the light bulbs in my house were all tungsten filament bulbs. The dim yellow light was particularly harmful to my eyes. During that time, everything I saw seemed yellow. In addition, the impression was often broken when a parent would give some money soon after saying that the light bulb in the house “flashes” and buy a new one with a few tens of watts.

Gradually, fluorescent tubes appeared, and the color temperature was much higher than that of tungsten lamps, so it seemed that the eyes were much more comfortable. Later on, all kinds of lights began to appear, such as LED lights, chandeliers, ceiling lights, flat lights, and so on.

Although there are more and more optional lamps, the LED bulb is the most practical and worry-free. Of course, although the bulb lamp is cheap and easy to use, it is necessary to see these indicators clearly when purchasing, so that you can choose the bulb lamp that is worry-free and practical.

Unlocking the Secrets of LED Bulbs: From Production to Performance, Appearance, and Components

LED Bulb Product process

LED Bulb Product process
  • The smoother the surface of the product, the higher its mold level.
  • Check to see if there are any bumps or other irregularities in the solder joints and whether they were done by manual soldering or by a reflow soldering machine, wave crest Soldering machine, SMD placement machine, PCB tinning machine, and other machines. These machines cost hundreds of thousands to millions of dollars. If LED lights are manufactured by these machines, their quality and reliability will be much higher than those produced by hand-soldered products.
  • Inspect for flaws and defects.

Color rendering index of LED bulb

Color rendering index of LED bulb

Currently, the parameters of LED lamps are luminous efficiency and color rendering index. Luminous efficiency must be greater than 80LM/W. The current indicator of luminous efficiency is 80-100LM/W, which must be greater than 80 LM/W but this indicator is in a growth period and by next year it will reach 100-120LM/W. The color rendering index can reach 0.8. There is no need to pursue this index above 0.85 unless you are engaged in work that requires high color such as painting.

Strobe

If a strobe is present, it can hurt young children at home. In other words, the larger the light-emitting area, the better.

Appearance and function

Take a look at the appearance, whether it looks artistic and whether it has intelligent control. Find out whether it has special functions that you need, such as voice control.

LED Bulb Place of the origin

China’s LED industry is centered in the Pearl River Delta region and the Minnan region. Many excellent LED companies are based in these two areas, where their products are exported to foreign countries in large quantities and their quality and technology are very mature. Shenzhen and Dongguan, both in the Pearl River Delta region, have many excellent companies with reliable quality; Zhongshan—also located in this region—is China’s lighting production center. There are a large number of LED workshops converted from lighting workshops, but they lack technical capital and equipment. They use price dumping and increase current to reduce costs while selling products with short lives to make profits.

The color-changing strip lights are called RGB strip lights. These LED lights can display any color of red, green or blue. It uses led chips of multiple colors so that you can change colors according to your preferences. RGB strip lights are the most common type of color-changing LED lighting. These lights can display any combination of red, green, and blue colors.

Photochromicis how we distinguish the various white colors that LED chips can produce. Photochromic is how “warm” or “cool” light appears. It is measured in Kelvin, with higher temperatures representing cool colors (blue tones) and lower temperatures representing warm colors (yellow light ). Usually, the general space uses 3000K and 4000K color temperature strip light But for some spaces, low color temperature strip light is very necessary, such as high-end hotels and villa clubs.

After Sales for LED Bulb

After Sales for LED Bulb

After-sales service is very important because LED lights can be used for many years. The price isn’t cheap, so it’s best to choose a well-known company, who often attaches importance to reputation and it is not so easy to become famous. Unknown companies can register after they sell out. New companies fall into bankruptcy or just go out of business.

Next, I will introduce the composition of the bulb lamp.

1. LED Bulb housing

LED Bulb housing

Let’s start with the shell of the LED bulb. The materials of the LED bulb shell are divided into PP material, ABS material, PBT material, and PC material. In terms of cost, the price of PP material is the lowest.

1.1 pp material

Among them, the cost of PBT and PC materials is relatively high, and the shell made of PC materials is relatively smooth and beautiful.

1.2 PC material

The LED lamp shell made of PBT material is generally frosted, and the frosted feel is comfortable and relatively high-end.

1.3 PBT material

2. LED Bulb cover

The lampshade of LED bulbs is usually made of PC and PP materials, and the cost of PP materials is the lowest.

  • PC material is relatively soft. Good light transmission. Brightness is high when the bulb is on.

  • PP material is relatively soft, with poor light transmittance and low brightness.

3.Drive power of LED Bulb

Drive power of LED Bulb

The driving power of LED bulbs is like the heart of the human body, which determines the life of the bulbs. The function of the driving power is to convert the power supply (general household 220V) into a specific voltage and current suitable for LED bulbs.

There are two main drivers for LED bulbs on the market.

Resistor-capacitor step-down drive:

It is composed of non-polar capacitors, filter capacitors, slice rectifier bridges, diodes, and other components. Generally, the lamp boards driven by resistors and capacitors are not made of aluminum alloy, with poor heat dissipation function, fast light decay, not durable, and generally low. LED bulbs with low price drive power supply with resistance and capacitance.

There are two main drivers for LED bulbs on the market.

Constant current source drive:

It is composed of transformers, filter capacitors, SMD rectifier bridges, resistors, small capacitors, and other components. The LED bulbs driven by constant current sources are durable and do not easy to burn out the lamp beads.

4. Lamp holder

lamp holder

The material of the lamp holder is iron galvanized, aluminum galvanized, iron nickel-plated, aluminum nickel-plated, pure brass, pure aluminum, and so on. The commonly used galvanized appearance is silver-white, which is relatively cheap, and the nickel-plated appearance is silver-white and yellowish, which is not easy to rust, and the cost is rather expensive.

The commonly used specifications of lamp holders are

E27 screw (E stands for Edison, 27 stands for lamp head diameter 27 mm)

E14 screw (E represents screw, 14 represents the diameter of the lamp head is 14 mm)

Conclusion:

You can purchase LED Bulb lights from kingornan in a variety of forms. The key to choosing the right LED Bulb light is understanding your market needs and choosing the best option for material, power, and color temperature.
