소형 형광등이라고도 하는 소형 형광등(CFL)은 백열등을 대체하도록 설계된 형광등 유형입니다. 많은 CFL이 기존의 백열등 설비에 들어갈 수 있습니다.

Frequently Asked Questions about CFLs

Why use compact fluorescent light bulbs?

소형 형광등(또는 CFL)은 기존의 백열 전구보다 에너지를 덜 사용하고 더 오래 지속됩니다. 그들은 장기적으로 돈을 절약하고 자주 변경할 필요가 없습니다. 또한 에너지를 덜 사용하기 때문에 환경에도 좋습니다.

Will CFLs work in the home?

예. 백열 전구와 동일한 기존 조명 소켓에 맞습니다. 가정용으로 백열 출력과 일치하도록 부드러운 흰색 소형 형광등을 구입하십시오. 전구를 구입할 때는 빛의 양(루멘 단위로 측정)을 최대화하고 필요한 전기량(와트 단위로 측정)을 최소화하기를 원합니다.

Will CFL bulbs really save me money?

예! 예를 들어 펜실베니아의 일반적인 전기 요금(일부 세계에서 가장 낮은 요금)의 경우 각 개조 CFL은 수명 동안 $30 이상을 절약할 수 있습니다.

How does a CFL bulb work?

소형 형광등은 수은 증기를 여기시켜 빛을 생성하는 아크 방전 램프입니다. 수은을 여기시키는 램프 끝의 전극에 전기가 가해집니다. 수은이 여기되면 램프를 가로질러 아크를 통해 전류를 다른 쪽 끝으로 전달합니다. 여기된 수은은 대부분의 에너지를 자외선(UV) 범위에서 생성합니다. 램프를 가로질러 뻗어 있는 UV 에너지는 가시광선을 방출하는 전구 내부의 흰색 코팅인 형광체를 활성화합니다.

Are CFLs really good for the environment?

예! 100W 백열 전구 하나를 CFL 전구로 바꾸는 것을 고려해 보십시오. CFL 전구는 빛을 많이 생산하지만 에너지의 1/4만 사용합니다. 모든 CFL 전구는 온실 가스 배출로 인한 기후 불안정성을 줄이는 데 도움이 됩니다. 다음은 백열등에서 CFL 전구로 소켓 하나만 변경하여 방지할 수 있는 오염 목록입니다.

Can I use CFL bulbs if I will be turning the lights on and off frequently?

Compact fluorescent light bulbs work best if they are left on for over 15 minutes each time they are turned on. CFLs can take up to 3 minutes to warm-up to reach the point of most efficient operation. Frequently switching them on and off can shorten the life of the bulb. If the life of the bulb is shortened significantly, you will not reap the full financial benefits (includes energy and life of bulb).

Don

The old ones did but they do not anymore. Due to phosphors in the new bulbs, the quality of light can now be manipulated and three-way CFLs are now available. The greenish cast is gone and the light has the same softness of the conventional bulbs we are used to.

Do CFL bulbs flicker and buzz like the fluorescent lights in old buildings?

No. Modern CFL bulbs utilize harmonic technology to eliminate the old problem of flicker and buzzing. This is not true of all compact fluorescents as inferior brands still have that problem.

What should I do if I break a compact fluorescent light bulb?

When a bulb is broken, the best thing to do is to wear chemical resistant glove to clean it up. The gloves you buy in the supermarket for household cleaning are sufficient. The gloves protect your skin from absorbing the mercury and from getting cut by the glass. The remains of one lamp can be disposed as normal waste since the amount of mercury is extremely small.

Can I use CFLs with a dimmer?

Standard CFLs cannot be used with a dimmer switch. However, there are dimmable bulbs, although they are more expensive. There are also 3-way bulbs.

CFL savings

Assuming you have the lights on for 8 hours a day you will save ~$1.12/month for every 100W fixture you switch to CFLs. The CFL will pay for itself in less than 6 months – and then you reap over 2 years of pure profit while saving planet!CFLs also have a much longer life than conventional incandescents.

Potential problems with fluorescents (including CFLs)

Note that the quality of fluorescents can vary enormously. In general to avoid this problem either i) buy from a manufacturer that you trust, ii) purchase from a vendor you can return bulbs to if there is problem, iii) get reliable 3rd party information such as from Consumer Reports or student projects, or iv) buy one bulb test it at home - if it works retrofit your entire home.

  • light quality (spectrum) - this should be on the package as noted as {{WP}color temperature}}
  • flickering, noise (whining) - only in the worst bulbs normally old.
  • unpredictable life span (too sensitive to shocks, surges?) particularly in some cheaper brands.[verification needed]
    • many CFLs are being installed in circuits that are controlled by dimmers, but not all CFLs are designed to tolerate dimmers, which can cause failures in power generation section of the lamp.[1] With the growth of dimmable CFLs and LVDs, this issue is declining.
  • Fluorescent bulbs still contain mercury, a hazard material leading to disposal issues, particularly in less developed regions where disposal is not regulated. The mercury levels in fluorescent lights (including CFLs) are now usually considered to be within safe limits. However you should take care not to break them.
