LED energy-saving lamp-What is the difference between E27 ceramic bulb lamp and E14 small screw candle lamp?

The differences are as follows:

1. The connectors are different. One is E27, and the other is E14.

2. The scope of use is different. E27 ceramic bulbs have a wider range of applications, such as homes, hotels, hotels and other indoor areas. The range of E14 small screw candle lamps is relatively small, and the largest amount is used in crystal chandeliers.

3. The appearance, structure and size are also different. The size of E27 ceramic bulbs can be very large, including A60, A70 and so on. The size of the E14 small screw candle lamp is very small.

4. The maximum power of E27 ceramic bulb can reach 12W, and the maximum power of E14 screw socket is 6W.

Characteristics of LED energy-saving lamps

1. Energy saving. The energy consumption of white LEDs is only 1/10 of incandescent lamps and 1/4 of energy-saving lamps.

2. Longevity, with a lifespan of more than 100,000 hours, which can be described as "once and for all" for ordinary household lighting.

3. It can work at high speed. If the energy-saving lamp is started or turned off frequently, the filament will turn black and break quickly, so it is safer.

4. Solid-state packaging, which is a cold light source type. So it is easy to transport and install, can be installed in any miniature and closed equipment, and is not afraid of vibration.

5. LED technology is making rapid progress, its luminous efficiency is making amazing breakthroughs, and its price is constantly decreasing. An era in which white light LEDs enter the home is rapidly approaching.

6. Environmentally friendly, no harmful substances such as mercury. The assembled parts of LED light bulbs can be disassembled and assembled very easily, and they can be recycled by others without being recycled by the manufacturer.

7. Light distribution technology expands LED point light sources into surface light sources, increases the luminous surface, eliminates glare, sublimates visual effects, and eliminates visual fatigue.

8. Integrated design of lens and lampshade. The lens has both light gathering and protective functions, which avoids repeated waste of light and makes the product more concise and beautiful.

9. High-power LED planar cluster packaging, and integrated design of radiator and lamp holder. It fully guarantees the heat dissipation requirements and service life of LEDs, fundamentally meets the arbitrary design of the structure and shape of LED lamps, and has the distinctive characteristics of LED lamps.

10. Significant energy saving. Using ultra-bright and high-power LED light source, combined with a high-efficiency power supply, it saves more than 80% of electricity than traditional incandescent lamps, and the brightness is 10 times that of incandescent lamps at the same power.

11. Ultra-long life of more than 50,000 hours, more than 50 times that of traditional tungsten filament lamps. LED adopts highly reliable advanced packaging technology - crystal welding, which fully guarantees the long life of LED.

12. No flicker. Pure DC operation eliminates visual fatigue caused by stroboscopic light sources.

13. Green and environmentally friendly. It does not contain lead, mercury and other polluting elements, and does not cause any pollution to the environment.

14. Impact resistance, strong lightning resistance, no ultraviolet (UV) and infrared (IR) radiation. There is no filament or glass shell, there is no problem of traditional lamp breakage, no harm to the human body, and no radiation.

15. Works under low thermal voltage, safe and reliable. Surface temperature ≤60℃ (when ambient temperature Ta=25℃).

16. Wide voltage range, global LED lights. 85V~264VAC full voltage range constant current to ensure that life and brightness are not affected by voltage fluctuations.

17. Using PWM constant current technology, it has high efficiency, low heat and high constant current accuracy.

18. Reduce line losses and cause no pollution to the power grid. The power factor is ≥0.9, the harmonic distortion is ≤20, and the EMI complies with global indicators, reducing the power loss of power supply lines and avoiding high-frequency interference and pollution to the power grid.

19. Universal standard lamp holder, which can directly replace existing halogen lamps, incandescent lamps and fluorescent lamps.

20. The luminous visual efficiency rate can be as high as 80lm/w. A variety of LED lamp color temperatures are available, with high color rendering index and good color rendering.

Energy-saving characteristics of LED lights

1. LED light source has high luminous efficiency. Comparison of luminous efficiency: incandescent light efficiency is 10-15lm, and tungsten halogen light efficiency is 12-24 lumens/watt. , fluorescent lamps 50-90 lumens/watt, sodium lamps 90-140 lumens/watt, most of the power consumption becomes heat loss.

2. LED light efficiency can reach 50-200 lumens/watt, and its light emission has good monochromaticity and narrow spectrum. It can directly emit colored visible light without filtering.

3. LED light source consumes less power. The power of a single LED tube is 0.03-0.06 watts. It is driven by DC and the driving voltage of a single tube is 1.5-3.5 volts. Current 15-18 mA has fast response speed and can be operated at high frequency. When used with the same lighting effect, the power consumption is one ten thousandth of that of incandescent lamps and one half of that of fluorescent tubes. If the light efficiency ratio is used LEDs, which are twice as powerful as fluorescent lamps, can replace half of Japan's incandescent and fluorescent lamps, saving the equivalent of 6 billion liters of crude oil every year. A fluorescent lamp with the same effect is more than 40 watts, while the power of each LED is only 18 watts.

4. LED light sources have a long service life. Incandescent lamps, fluorescent lamps, and tungsten halogen lamps use electronic light field radiation to emit light. The filament is easy to burn, heat deposits, and light attenuates. However, LED lamps are small in size. , light weight, epoxy resin encapsulated, can withstand high-strength mechanical impact and vibration, is not easily broken, has an average lifespan of 30,000-50,000 hours, and the service life of LED lamps can reach 3-5 years, which can greatly reduce the maintenance costs of lamps and avoid frequent replacement The suffering of the lamp.

5. Strong safety and reliability, low calorific value, no thermal radiation, cold light source, safe to touch, able to accurately control the light pattern and angle of light, harmonious light color, no glare, and does not contain mercury , sodium and other substances that may be harmful to health.

6. LED light source is environmentally friendly. LED is an all-solid luminous body, impact-resistant and not easily broken. Waste is recyclable and pollution-free. It reduces a large amount of harmful gases such as sulfur dioxide and nitrogen compounds, and improves the production of greenhouse gases such as carbon dioxide. People's living environment can be called "green lighting source."

7. There are currently three technologies for producing white LEDs: one, which uses the principle of three primary colors and three ultrasonic red, green, and blue LEDs that can be produced. High-brightness LEDs are mixed into white according to a light intensity ratio of 3:1:6. Two types are used. Ultra-high-intensity InGan blue LEDs are used. A small amount of yttrium diamond garnet-based phosphor is added to the tube. It can be excited by blue light. Produce yellow-green light, and this yellow-green light can be combined with the transmitted blue light to synthesize white light. The third type is non-UV LED, which uses ultraviolet light to excite three primary color phosphors or other phosphors to produce white light mixed with multiple colors.

8. LED light sources are more energy-saving. Of course, energy saving is the main reason why we consider using LEDs. Maybe LEDs are more expensive than traditional light sources, but it takes one year to save energy to recoup the investment in light sources, thereby gaining 4 -Energy-saving net cap period of several times each year for 9 years.
