LED water proof As the name suggests, the led cable to enjoy wetland settings,the water proof technology should provide a secure against severe work circumstance. Until now, There are many kinds of led water proof in led market. However, in the strict sense,.but a perfect mastery of led water proof connector are really slim. The level of led water proof has reached IP68 . That’s not easy, that’s for sure.why?
it must execute test that put into water which is about ten meters and work for two week. Or put into water which is about One hundred meters and work for half day.
By those standards, Have been really difficult for other manufactory . but we Using this method to make 2 pin waterproof connector.
LED are not like energy-saving lamps. It is starting when there is no high voltage. The led operation current is not that high(in general the scale is 10mA~50mA). but many users find that the led would carry more bigger at starting instant. That’s way?
This phenomenon is due to the capacitance . in general there are have filter capacitance in led circuit . the specific place that it stood hard by rectifier circuit. Work process is : the filter capacitance will process of charging process when led string instant. But this is so short time. The charging current is big if the relatively lower resistance(can reached 1~2A)。but this effect is so small for LED circuit. In conclusion , the current canThe starting current be used as Rated current, The calculating formula of Rated current as: power/voltage , for example 30W/220V/0.136A(amp)
LED Waterproof Connector of the technology has tended to be mature, in many high-quality have been used TheLED Waterproof Connector 。glandsaresuitable forthe use in machine and installation equipment,
measuring and regulation equipment,constructionsite installation
and many other application areas.Below are a list of LED Waterproof Connector:
Infrared light and ultraviolet light and high power led moduleThe high power led module refers to led module more than 1 watt. Would there be any infrared light and ultraviolet light when high power led module is work.The spectrogram of high power led modules(in general use the blue light photolum inescent phosphor ).as follows:
a few are seen to infrared light and none ultraviolet light in The spectrogram of high power led modules. On other word , yet most no infrared light and ultraviolet light between at visible wavelength 400-635nm. And of course there are has professional infrared led module and ultraviolet led module such as UV led strip. The wavelength less than 400nm and were larger than that 640nm.they call infrared light and ultraviolet light.But the energy radiation of ir (uv) led module is small,small power uv led module just have 0.036-0.072W. So we can imagine what the uv led strip and ir led strip is be secure。
Our current talk topic is photosynthesis of plants with plants lamp.
we all know that photosynthesis is the process that enables plants to live and grow.
the light wave is most fundamental condition for Photosynthesis.the length wave between 400nm ~ 720nm.400 ~ 520nm(blue light)and 610 ~ 720nm（red light). red light and blue light top contributor for photosynthesis. Actually the plants don’t green light so The 520 ~ 610nm（green light）of radiant energy absorbed by the photosynthetic has been small.
While there are have lots device suitable to be used in plant grow. they include :Pressure sodium lamp, metal halide lamp, ceramic metal halide lamp, microwave sulfur lamp, Plasma lamp, fluorescent lamp, electrodeless lamp and three color lights, LED light rare earth plant etc. Sodium lamp, metal halide lamp and LED lamp plant are is most commonly used.
The LED PVC light words is made up of light box, light word resource and acrylic vacuum panel.
Characters of LED PVC light Words: high luminance, energy-saving, long life service, lightening in gold white color, strong to transmit in fog. usage: suitable for lightening on road, airport, station and enterprise. The power is most import factor for LED PVC light words. But how to calculation? Now let’s talk about.
In general ,the calculation formula of LED module power is: quantity * 0.24W. there are have a lots different brand power supply. The power supply has to have good quality. Remember to reserve some power space in design for LED PVC light. The overstretched power supply could reach break point. In normal ,the power supply can’t overload than 70%。
The LED drive circuit determines that LED service time
The led drive circuit has a important impact on the led system .the drive circuit can be changed into fit drive voltage form adapter. For Led drive circuit and LED load provide electrical energy.
The mainly function of LED drive circuit:
What character traits does such LED drive circuit; it should have constant current characteristics.
Especially as input voltage of adapter changes, the led current still can keep immobile.
Make sure that Led load current is stable
To void that the LED drive current to exceed the maxim rated value.
The LED chromaticity are consistent with LED bright
Low-power scheme is best.
The Scale diagram of LED Damage
Damage rate of LEDs as 10%
Controller of LED as 7%
LED install as 31%
The drive of LED as 52%
What is “high voltage led”?
The high voltage led also call high power led module. The high power led module is a series connection led module product by LED factory. This is one of those(led module).In fact, there are lots of kinds LED module in earlier years.them in bunches and series connect together. In order to achieve that a lots of kind power and voltage led module.of course small led module also can series connect to together to achieve a hight power led module. who called him “LED module array”. For example a 30W LED module array. It’s a combination of 25 pcs 1W led module with 5 parallel and 5 series.
