1, LED floodlight brightness (MCD) is not the same , not the same quote .
2 , antistatic antistatic ability and strong ability of the LED, long life expectancy , so the quote is high. The LED is usually static than 700V LED lighting for talent .
3 , the common wavelength of the LED, the common color as the color co- demand , the quotation is high. No LED spectral separation device manufacturers is difficult to produce color LED produces pure commodity.
4 , the leakage current
LED floodlight is one-way conductive light , if there is a reverse current is
called leakage, leakage current is large LED, short life expectancy , lower price .
5 , the usefulness of different viewpoints luminous LED luminous point of view
is not the same . Particularly luminous viewpoint , higher offer. If all diffusion
angle , higher offer.
6 , the key is not the same quality of life expectancy is life expectancy , life
expectancy from the light fades resolution. Light decay, long life expectancy , long
life expectancy , offer high .
7 , Chip
LED floodlights for the chip luminous body , not the same chip , offer very different
. Japan, the United States more expensive chips , chips are usually lower than the quotes
made in Taiwan and Japan and the U.S. (CREE).
8 , the size of the chip to chip the size of a side showed great quality LED chips
are better than small chips . Quotes are proportional to the size of the same chip .
9 , the usual LED colloidal gel is usually an epoxy resin , plus a UV resistant and
fire retardant in LED quotes expensive, high-quality outdoor LED lighting should be UV
and fire . Each product will have a different plan , a different plan applies to a
different use, robustness planning LED lighting include: electrical safety , fire safety,
applicable environmental safety , mechanical safety , well-being safe , secure use of time
and other factors. From the viewpoint of electrical safety perspective, should fit about
the world , national norms .
Because LED is a new product , China lags behind the national norm , but the national
supply of goods qualifying test. World safety certification ( such as GS, CE, UL , etc. )
and the amount of the State 's quality certification of LED lighting quotes must be high,
since these goods in the security planning is robust . Consumer attention is to carefully
distinguish the authenticity of the certificate , and now has the world commodity security
certification and national certification are not many manufacturers .
From the well-being , the commodity quote data plan to use non-toxic high, especially
indoor LED floodlight , do not choose the smell of cheap LED lighting, LED manufacturers
currently only a small few data are produced with non-toxic , the distinction between way
to be able to leave with the nose directly , many less than smelly odor-free goods offer.
Like lead, mercury , cadmium and other toxins need professional analysis . From the
applicable environmental safety perspective, there are reliable dust-proof planning,
information fireproof , anti-UV , anti- low temperature cracking quoted LED products is high.
