What does LED light mean, and what does the E27 lamphead refer to?

LED lights are light-emitting diodes.

It is a solid-state semiconductor device that can convert electrical energy into visible light, which can directly convert electricity into light. The heart of the LED is a semiconductor wafer, one end of the wafer is solidified to a bracket with silver glue or white glue, and then the chip and circuit board are connected with silver wire or gold wire, surrounded by epoxy resin.

Seal it up. The E27 lamphead is a commonly used LED lighting with the bulb thread code E27.

Lamp. The letter E stands for Edison.

The number after the "e" indicates the integer value of the outer diameter of the thread of the lampholder. Lamphead big path, lamphead trail. The light mouth of the big path, the light mouth of the small path. The unit is mm.

LED lamp is a kind of E27 lamp head light source lamp head made of semiconductor light-emitting elements, which is used for E27 lamp light source interface, and the lamp head with a diameter of 27mm has a spiral text for screwing into the E27 lamp interface. is the most commonly used type of luminaire interface.

LED is a light-emitting diode, which is an energy-saving light-emitting element with high luminous efficiency and long life! The E27 is a model of the light port! It is the model of the lamp port on the bulb that we commonly use! There is also an E40 one, which is the headlight port!

LED is the meaning of light-emitting diode, and E27 is estimated to be a certain model.

The size of the spiral mouth, E14 and E27 correspond to the 14mm and 27mm spiral mouths respectively; B22 refers to bayonet lampholder.

The commonly used bulb thread code is E27, lamp head large diameter, lamp head small diameter.

The large diameter of the lamp port, the small diameter of the lamp port, the unit is mm.

LED lamps are light-emitting diodes, which are solid-state semiconductor devices that can convert electrical energy into visible light, which can directly convert electricity into light. The heart of the LED is a semiconductor wafer, one end of the wafer is solidified to a bracket with silver glue or white glue, and then the chip and circuit board are connected with silver wire or gold wire, and the perimeter is sealed with epoxy resin.

The E27 lamphead is a commonly used LED lighting head with the bulb thread code E27. The letter e represents the spiral lampholder of the Edison thread, and the number after the "e" indicates the integer value of the outer diameter of the thread of the lampholder. Lamphead big path, lamphead trail.

The light mouth of the big path, the light mouth of the small path. The unit is mm.

1. What does LED bulb E27 mean.

The LED bulb E27 refers to the use of a 27mm diameter screw head. In addition, the model of the ordinary bulb commonly used indoors is also E27, so if the LED bulb of E27 is used, then the two can be used interchangeably, to a certain extent, it brings a certain convenience.

Second, how to buy LED lights.

1. When you go to ** to buy LED lights, you need to carefully observe the outer surface of the lamp to see that it can produce uniform light, so as to judge whether its quality is good or bad. If the LED light is uneven, then the quality of the lamp beads inside it must be bad, this kind of LED lamp is an inferior product, the use time is not long, so special attention should be paid.

2. The welding of LED lamp beads is also a major audit standard, and the welding points of LED lamps are very smooth, which determines the long-term use of lamps. However, some small manufacturers produce LED lamps, which have more burrs in their welding joints, and may even appear virtual welding, which affects the normal use in the later stage.

3. Special attention should be paid to the heat dissipation effect of LED lights, after all, the sensitivity of LED lights to temperature is very high. If the temperature is too high, it will lead to a significant reduction in its life, so it is necessary to see whether the aluminum skin inside the LED lamp is large enough, so as to ensure that it can dissipate heat normally and avoid the LED lamp being burned out.

What does LED bulb E27 mean, and how to buy LED lights, I will introduce it here, do you understand it? The selected LED lights should meet the standards as much as possible, so as to ensure normal use in the later stage and avoid unnecessary trouble.
