What are the types of LED bulbs and what are the differences between them?

LED bulbs mainly have 1Incandescent lamps with low energy conversion efficiency, but good color rendering and easy to use. 2.

High luminous efficiency, but expensive fluorescent lamps. 3.Discharge lamps with high efficiency and long life.

In comparison, the third type of LED bulb is the most cost-effective.

There are three categories, spherical and pointed, and light cup type. Spherical: Luminous on one side, the lower part is a plastic or aluminum shell.

Annular + top glowing, commonly known as corn bubbles, because the shape of the small yellow dot structure is very similar to corn. The three-pronged shape is also regarded as the luminous way of corn bubbles, but it has a more scientific structure than corn bubbles, so it is more popular at present; Light cup type:

It's basically an old-fashioned product, just like a spotlight.

LED indoor lighting fixtures are currently subdivided by name: spotlights, ceiling lights, ceiling lights, downlights, bulb lights, tubes, flat lights, kitchen and bathroom lights. Among them, the spotlights are:

Ceiling spotlights, track spotlights, general small spotlights, normally for a specific position to irradiate at an angle needs to use spotlights (the angle of spotlights can be made into 15 degrees, 30 degrees, 45 degrees, 60 degrees, 90 degrees, etc.), but because some spotlights (ceiling spotlights) according to its installation method (embedded to the ceiling), many factories call ceiling spotlights and downlights together

When buying a light bulb at home, you need to choose a regular light bulb according to its wattage and type. So what is the difference between ordinary light bulbs and LED bulbs? PChouse will take you to find out.

First of all, the power consumption of the two is different, in general, LED lights will be more energy-saving, and their power consumption is mostly about one-third of ordinary lights, for example, 15W LED is equivalent to 40W ordinary lights.

The luminous principle of the two is different, ordinary lamps will first exchange electrical energy into heat energy and then convert it into light energy, compared with ordinary lights, LED skips the step of converting into heat energy and directly converts it into light energy. LED lights use direct current, and many products can also adjust the brightness. Ordinary lamps use alternating current and cannot be adjusted brightness.

Finally, a long life is not the same. Some people call it the longevity lamp, which means the lamp that never goes out. Solid cold light source, epoxy resin encapsulation orange group hidden, there is no loose part in the lamp body, there is no filament luminous easy burning, thermal deposition, light decay and other shortcomings, the service life can reach 60,000 to 100,000 hours, more than 10 times longer than the life of ordinary bulbs.

LED bulbs, as you said, are divided into three categories, spherical and pointed, and light cup type.

Spherical: 1Single-sided luminescence, the lower part is a plastic shell or an aluminum shell (some spherical surfaces have a small curvature and look like an inverted trapezoid);

2.Annular + top glowing, commonly known as corn bubbles, because the shape of the small yellow dot structure is very similar to corn.

3.The three-pronged shape is also regarded as the luminous way of corn bubbles, but it has a more scientific structure than corn bubbles, so it is more popular at present;

Light cup type: basically old-fashioned products, just like the spotlight cup, there are many limitations, so it is close to being eliminated;

Pointed: 1Single-sided light (similar to spherical, just a pointed + lens);

2.three-pronged shape (ibid.);

3.The chrome plating emits light on three sides, this is very high-end, and the luminous efficiency is also good, but there is no luminous point on the top;

4.The candle type is just a sharp bubble with a tail, which is basically the same as a sharp bubble;

There are also according to the power supply is divided into high voltage and low voltage, the material is divided into die-casting aluminum, car aluminum, plastic, the color temperature is divided into warm white, positive white, middle white (there are other colors, such as red light, yellow light), according to the interface is divided into screw (E27, E14), bayonet, MR16, GU10, can also be divided into dimmable, non-dimmable, lamp beads can be divided into small power, high power, straight insertion, patch, drive can be divided into isolated, resistance and capacitance step-down, etc.

There are also spotlights, track lights, ceiling lights, fluorescent lights, RGB lights, light strips, and outdoor street lights!
