Do you know what an LED bulb is

The status quo of LED bulbs LED lighting is mainly high-power white LED single light. Led lighting is a collective term for led lamps. With the further maturity of LED technology, LED will make more and better developments in the field of design and development of residential lighting lamps. In the 21st century, room lighting design will be based on led lighting bulb design as the mainstream, while fully embodying the development trend of energy-saving, healthy, artistic and humanized lighting, and become the dominant room lighting culture.

Traditional incandescent lamps have high energy consumption and short lifespan. Under the global resource shortage environment, they have gradually been banned by governments from all over the world. The alternative products are electronic energy-saving lamps. Although electronic energy-saving lamps have improved energy-saving effects, they have been used in many ways. Heavy metal elements that pollute the environment are contrary to the general trend of environmental protection. With the rapid development of LED technology, LED lighting has gradually become the best choice for new green lighting. LED is far superior to traditional lighting products in terms of light-emitting principle, energy saving, and environmental protection.

Since incandescent lamps and electronic energy-saving lamps still occupy a very high proportion in people’s daily use, in order to reduce waste, LED lighting manufacturers must develop LED lighting products that conform to existing interfaces and people’s habits, so that people do not need to replace them. A new generation of LED lighting products can be used in the case of the original traditional lamp base and wiring. So LED bulb lights came into being.

Introduction to the principle of LED bulbs

Light-emitting diode bulbs are fundamentally different from traditional incandescent lamps in terms of structure and light-emitting principle. Diode is a common component in electronic circuit, it is made of semiconductor PN junction, plus electrode lead and tube case. A diode has two electrodes with a PN junction, so it is called a diode. The diode has unidirectional conductivity. There are many types of diodes, the common ones are detector tubes, rectifier tubes, voltage regulator tubes, switch tubes, damping diodes, light emitting tubes, photoelectric tubes, etc.

Light-emitting diodes are usually made of semiconductor materials such as gallium arsenide and gallium phosphide. They emit light when passing a forward current. The color of the light depends on the material used, and can emit red, yellow, green, and infrared light. Light-emitting diodes are generally packaged in transparent plastic, with the long pin being the positive electrode, and the short pin being the negative electrode. Some light-emitting diodes have three lead-out pins, which can emit two colors of light according to the pin voltage.

Those about the advantages of LED bulbs

1. Energy-saving research data show that because LED is a cold light source, semiconductor lighting itself does not pollute the environment. Compared with incandescent lamps and fluorescent lamps, the energy-saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of that of ordinary incandescent lamps and 1/2 of that of fluorescent tubes.

2. Healthy LED is a green light source. LED lights are driven by DC, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong light-emitting direction; good dimming performance, no visual error when the color temperature changes; cold light source Low heat and safe to touch; these are not reachable by incandescent and fluorescent lamps

What users say about DD LIGHTING

The life expectancy of the bulb is longer than mine, so it may take a while for me to comment on the quality. The price is good and the service is good!


I have been looking for the brightest possible light bulbs, and it feels like they are definitely them.The difference between these LED lights and standard soft white is great.


These lights are very bright, very bright. They provide good coverage and the light is on the cooler side.


These can be well covered in general in the backyard or side yard.These are great bulbs and we can easily install them.


The light is soft and the driver chip is stable. There is no flicker. The logistics is fast, and the packaging is relatively strong and has a foam layer bottom which is very good.


Simple and beautiful, too complicated shape will shading, and dust is not easy to clean. This kind of ceiling lamp is much more convenient, the lamp beads are good, it is more durable, and the dust is easy to take care of. The brightness is relatively high and very practical.


It is very suitable to be placed on the balcony. The previous lamp was a 40-watt circular energy-saving lamp. This led lamp is 19 watts brighter than the 40-watt one. The shape is simple and generous, and it is easy to do and hygienic. The most important thing is the long use time.


Simple but not simple, easy to install, simple to control, good material, reliable quality, reliable to use, durable, reliable in light, economical in power consumption, suitable for household use, without too complicated design, easy to clean.
