(1) color: currently, basically have red, green, blue, cyan, yellow, white, amber.
(2) current: according to different power level, the commonly used LED current 20 ma – in 2 a.
(3) voltage, voltage and color, usually red, green, and blue VF between 1.8 to 2.4 V; White, blue, green voltage between 3.0 3.6
(4) reverse voltage Vrm: LED […]
And, on the other hand, China is a agricultural country, with the maturity of LED technology, LED lighting application in rural households and agricultural illumination is more and more widely. Lighting applications in agriculture, crop whitening treatment, technological measures are commonly used in agricultural production.
Before using the traditional way is in front of the incandescent […]
According to statistics, from 80% to 90% of the domestic LED business now most of the orders from overseas, while the domestic market has failed to open, including some of the industry’s leading companies. With the growing popularity of the domestic LED energy-saving lamps, the LED companies are slowly, the focus turned to domestic market, […]
2, drive circuit, a complex problem:
in terms of voltage matching, unlike ordinary incandescent bulbs, LED can be directly connected to 220 v ac mains. LED is 2-3. V low voltage drive, must to design complex conversion circuit, different USES of LED lights, with different power supply. B. in terms of current supply, the LED of […]
Referred to as the LED light of hope, since 1964, has grown to popularize lighting era, its energy saving, environmental protection, high brightness, small power consumption, long life, impact resistance and other advantages, foreground is very wide; In the beginning stages of indoor lighting, and its inherent shortcomings, mainly in the following aspects:
1, the inconsistency […]
Semiconductor lighting (including the leds with and other application products) is one of the country seven strategic emerging industries, in the next five years, the LED industry chain, product gross margin will return to the rational and the norm of the middle and lower reaches, but the future market competition is still fierce.
With the correct […]
According to a survey in April 2013, the global retail price of LED light bulbs continued downward trend. Global retail price of LED bulb which can replace 40w incandescent seems to decreased 5.7%, to $16.1 .Global average price of LED bulbs which can replace the 60w incandescent, fell 1.2% in April, to $23.8. Except average […]
There are three kinds of LED Candle bulb in No.1 lighting’s product range, 3014 Version, 5630 version and COB version. We provide 3 kinds to meet the different requirements from customers all over the world.
Here are the differences among them:
1.Lumen difference: 3014 version is has the highest lumen, around 230Lm, 5630 version has the next, […]
Lighting design must consider light source intensity, and the luminous flux of the lighting object.
The intensity of light source measurement unit is Lumen (Lumen). Intensity of illumination of the measuring unit is Lux. The relationship between the two is 1 Lux = 1 Lumen/m2
Suppose we have a 10 w led lamp, who is the total […]
As new green lighting technology, high-power white LED has high optical conversion efficiency, low energy consumption, long service life, less maintenance etc. It is gradually applied to all kinds of lighting area.
LED long life is based on the safety of working environment, for LED lighting, there are two main threat to affect their life: one […]
LED light-emitting diode, is a kind of shining semiconductor electronic components, it can directly turn the electricity into a light.
This new way of light-emitting LED has the characteristics of other similar products do not have: high light efficiency, long life, energy conservation, environmental protection, no radiation, etc.
LED’s application scope is quite wide, it is mainly […]
LED is no longer a fresh vocabulary in our daily life, people get more and more familiar with his energy saving environmental protection, and efficient. From the LED MR16 lamp to LED TV, more and more LED product appeared in our daily life.
How many areas that LED can be applied? What roles it plays? Let […]
