Are LED lamp beads more power efficient than LED bulbs?

Should it mean high power LED lamp beads and low power LED bulbs? In fact, the so-called high-power and low-power refers to a single LED light-emitting body (chip), the power of the overall lamp depends on the total number of these LED chips.

Should it mean high power LED lamp beads and low power LED bulbs? In fact, the so-called high-power and low-power refers to a single LED light-emitting body (chip), the power of the overall lamp depends on the total number of these LED chips.


Strictly speaking, as long as the production process is correct, both high and low power LED lamps have the characteristics of power saving and long life. It is just that the high-power lamp bead chip has concentrated heat, requires a certain heat dissipation device, and the cost is relatively high. Therefore, the quality of high-power LED lamp beads is better than that of low-power light bulbs generally made at low cost.


Regardless of the high and low power LED lamps and current energy-saving lamps, the brightness is similar. That is to say, the luminous efficiency of the same wattage LED lamp and energy saving lamp is similar. However, CREE's new LED chip has reached a luminous efficiency of 200 lumens per watt, and it is difficult for energy-saving lamps to exceed this threshold.


High-power LED lamp beads refer to the power consumption of a single LED chip above 1W. Most of the high-power LED lamps for household use are composed of 1 to 5 1W lamp beads, which are mainly used as auxiliary light sources such as spotlights and downlights or decorative light sources.


The low-power LED light bulb is a combination of several to dozens of low-power (about 0.06W) LED chips or small lamp beads. It has a shell structure similar to a traditional light bulb, which is relatively simple to use. Generally, it is used as a place where the brightness of the bathroom, aisle, night light, etc. does not need to be too high and it needs to be lit for a long time.


What is the relationship between LED chips and LED lamp beads

The LED chip is a sub-component of the LED lamp beads, and is an important part of it. The LED chip emits light.

LED lamp beads, whether plug-in or patch type, are composed of five parts: bracket, silver glue, chip, gold wire, epoxy glue, white LED and phosphor.

In terms of luminous colors, there are only three types of mainstream LED chips: R red, G green, and B blue. White LEDs are made up of blue light chips and yellow phosphors.

If you want to learn more about the LED structure, you can learn more on the Internet, and also welcome me to communicate more.
