LED Lamp - Introduction of LED
LED
(light-emitting diode) is a kind of semi-conductor diode that can
generate light. It is an environmental friendly product with high
efficiency and long life span.

Advantages
|
|
1.
|
Save more energy
|
|
LED
lamp has a higher luminosity (about 50-200 lm/W) when comparing with
other kinds of lamps (incandescent lamp: 12-24 lm/W; fluorescent lamp:
50-70 lm/W; sodium lamp: 90-140 lm/W). While LED lamp doesn’t transfer
most of its energy into heat, it saves more power. For example, only 8W
is needed for a LED fluorescent lamp which gives the same effect as a
40W fluorescent lamp. Moreover, LED lamp can produce single color in
good quality, narrow-spectrum light and visible color light directly. |
2.
|
Longer
life span
|
|
LED
lamp is small in size, light, in epoxy packing, which makes it
difficult to be damaged by external shock and vibration. While its life
span can reach 100,000 hours, LED bulb’s life span is much longer than
that of Halogen Lamps (about 20,000 hours) and Filament Lamps (about
30,000 hours). In other words, you can use the LED lamp for more than
10 years under a daily usage of 8 hours. |
3.
|
Environmental
friendly
|
|
Light
source of LED lamp contains no ultraviolet and infrared, and any other
harmful substances such as mercury. Moreover, it is solid state
components, sturdy, recyclable, limiting the emission of harmful
substance such as CO2 and nitride. These
characteristics are all good for environmental protection. |
4.
|
Low
heat
|
|
As
LED lamp does not need a filament to illuminate, the heat energy
generated is comparatively low. The lamp converts all electrical energy
into light energy instead of heat energy, therefore no energy will be
wasted; and the lamp is much safer and will not burn human’s skin with
low heat emission. |
5.
|
Durable
and safe
|
|
LED
lamp is low in heat, with no heat radiation, therefore it is safe to
touch directly; it contains no harmful substances, such as mercury and
natrium. |
6.
|
Wide
range of application
|
|
Since
LED lamp can be very small in size, it is good for different kinds of
products in usage and design. |
7.
|
Instant
start
|
|
Unlike
HID lamps and other traditional lamps, LED lamps can be lightened up
very quickly. Starting temperature does not affect the starting and
response time of LED lamps. Moreover, switching on/off will not lead to
aging or reduction of life span. |
LED 燈 - LED (發光二極管) 簡介
LED
(發光二極管)是一種可發光的半導體。它是一種環保產品,具備高效能及特長壽命。
|
優點
|
1.
|
效果更佳,並節省更多能源
|
|
LED
燈的光源發光率較高,可達到50-200流明/瓦,與其他燈相比(白熾燈:12-24流明/瓦;光管:50-70流明/瓦;鈉燈:90-140流明/
瓦),因沒有把大部分的耗電變成熱量損耗,因而節省更多能源。以一支40瓦的光管為例,相同效果的LED光管只有8瓦。而且LED燈的單色性好,光譜窄,
無需過濾,可直接發出有色可見光。 |
2.
|
更
長壽命
|
|
LED
燈體積小、重量輕、環氧樹脂封裝,可承受高強機械衝擊和震動,不易破碎。另,它的壽命可達100,000小時,因此以LED燈製作的燈泡的壽命比鹵素燈
(約20,000小時)和鎢絲燈泡(約3,000小時)更長。如果每天用8小時,LED燈可以使用超過10年。 |
3.
|
環
保
|
|
LED
燈的光源不含紫外光和紅外線,亦不含水銀等有害物質。此外,LED燈為全固體發光體、耐衝擊不易破碎、可回收、減少大量二氧化碳及氮化物等有害氣體,以及
減少二氧化碳等溫室氣體,皆有利環保。 |
4.
|
低
熱度
|
|
LED
燈不需要鎢絲發光,因此不會釋放過高熱度。它能把所有電能轉化為光能,因此能量並沒有浪費掉。它比其他燈更為安全,亦因為其低溫而不會傷害人們的皮膚。 |
5.
|
安
全可靠
|
|
LED
燈低溫度、無熱輻射,可以安全觸摸;不含汞、鈉元素等可能危害健康的物質。 |
6.
|
用
途廣泛
|
|
LED
燈體積可以非常小,便利於各種設備的佈置及設計。 |
7.
|
可
立刻發亮
|
|
與HID
燈和傳統燈泡不同,LED燈的回應時間在微秒級別。它的運作和反應時間不會受溫度影響。而且開關並不會使其老化或縮短其壽命。 |
