Why LED Lamps Replace CFL Lamps
★Disadvantages of CFL Lamps
●Disadvantage 1: Large size, can only be used for basic lighting
Fluorescent lamps must have a certain length of tube diameter due to its light-emitting principle. Therefore, the volume of the lamp body is relatively large, and the design of the lamp is more difficult. It can only be used for basic lighting, and cannot be used for key lighting.
●Disadvantage 2: General color rendering
Fluorescent lamps have good or poor color rendering index, and its color rendering is based on the type of phosphor. If the phosphor in the lamp is a five-primary phosphor, the display index can reach 90+ (but the price will be relatively expensive).
●Disadvantage 3: Dimming is difficult
Fluorescent lamps can be dimmed, but the control technology is much more complicated than LED lamps and requires special driving appliances.
●Disadvantage 4: strobe
This is the fatal point of fluorescent lamps-strobe. Of course, as long as the gas discharge lamp has a stroboscopic phenomenon, this is caused by the periodic change of the current.
●Disadvantage 5: electromagnetic interference
Because there are electrical appliances in the gas discharge lamp, it will have some more or less electromagnetic interference. In some occasions that require the use of electromagnetic interference-free products, such as recording studios, operating rooms, etc., fluorescent lamps are not suitable for use.
★Ten Advantages of LED Lights
- Advantage 1 the LED body is very compact
LED light is a small, very fine LED chip encapsulated in transparent epoxy resin, so it is very small, very lightweight, and can save a lot of materials and space in production and application. - Advantage 2 very low energy consumption
The working voltage of LED lamps is generally only 2~3.6V, and the working current is only 0.02~0.03A. That is to say: it consumes no more than 0.1W, and the power consumption is 90% less than incandescent lamps with the same light efficiency, and 70% less than that of energy-efficient lamp. Therefore, only LED can be called a real energy-saving light source!
- Advantage 3 strong and durable
The small epoxy resin particles are extremely difficult to break, and there is no loose part of the entire lamp body. The chips inside are extremely difficult to break, and there are few volatilization and melting due to thermal effects. These advantages make the LED hard to damage. Compared to ordinary bulbs and fluorescent lamps, LEDs can be described as solid, sturdy and countless times durable.
- Advantage 4 Long Service Life of LED lamp
Under the appropriate current and voltage, the service life of the LED lamp can reach 100,000 hours, that is, the theoretical life of the product reaches more than 10 years, which has a longer service life than other types of lamps.
- Advantage 5 Safe Low Voltage
LED lights use low-voltage DC power (which can rectify AC to DC), and the power supply voltage is between 6~24V, which varies depending on the product. In short, it uses a DC power supply that is safer than a high-voltage power supply, and is particularly suitable for homes and public places.
- Advantage 6 Wide range of application
Due to its small size, each unit LED chip is a square or a circle of 3~5mm, so it is more suitable for the preparation of devices with complex molding processes. For example, for the production of soft, bendable lamps, lamp strips, and special-shaped lamps, currently only LEDs are suitable.
- Advantage 7 richer colors
Previously, the colors of lamps on the market were very single. To achieve the purpose of color, one was to paint or cover the colored pieces on the surface of the lamp, and the other was to fill the lamp with inert gas to emit light, so the richness of color was limited. LED is digitally controlled, and the light-emitting chip can emit a variety of colors, including red, green, and blue ternary colors. It is with these ternary colors that through the system control, the colorfulness of the world can be restored.
- Advantage 8 Less heat dissipation
LED is a more advanced cold light source. It does not radiate a lot of infrared and ultraviolet rays like incandescent lamps and fluorescent lamps, so it is especially suitable for the lighting of valuables such as cultural relics, jewelry, high-end cosmetics and so on. There is almost no current heating effect like an incandescent lamp, and it will not be affected by thermal expansion and contraction. It will not make the bulbs yellow, accelerate the aging of the lamps, and will not cause a greenhouse effect on the surrounding environment.
- Advantage 9 Less environmental pollution
LED’s protection for the environment is mainly manifested in three aspects:
1) No harm from metallic mercury. LED lamps do not use high-risk mercury like fluorescent lamps, and there will be no public hazards such as mercury ions or phosphors that may leak during the manufacturing process or after damage.
2) The epoxy resin used to manufacture LEDs is an organic polymer compound. After curing, it has good physical and chemical properties, high bonding strength to wafers and metals, hard and flexible, stable to saline and most solvents, and not easy to damage. Even if it is damaged or aged, it can be recycled and reused without causing pollution to the environment.
3) The particle layout of LED lamps and display screens generally produces scattered light and rarely generates light pollution.
- Advantage 10 Cost savings
Compared with incandescent lamps, fluorescent lamps, and LED lamps, the purchase price is higher. However, because the energy consumption of LEDs is particularly low, a large amount of electricity can be saved in the long run, and the investment in lamp replacement can be saved, so the comprehensive use cost is more cost-effective.
★Advantages of LED headlights on Autos
- Compared with the traditional bulb bulb with a delay of 0.3 seconds, the LED lamp is lit without delay, and the response time is faster, thereby preventing rear-end collision.
- Stronger seismic performance.
- The luminous purity is high, no lampshade filtering is required, and the optical wavelength error is within 10 nanometers.
- The luminous heat is very small, and the heat resistance of the lamp material is not very high.
- The light beam is concentrated, which is easier to control, and does not need to use a reflector to collect light, which is helpful to reduce the depth of the lamp.
- When the power consumption is low, when the same brightness of the traditional bulb is reached, the power consumption of the LED lamp is only 6% of the traditional bulb, which saves electricity and fuel.
- Long life, no filament structure, no heat, normal use for more than 6 years.
- Vehicle control circuit is not easily oxidized.
