Control of tungsten lamp with infrared pulse
the infrared receiver connected to the relay then access tungsten lamp. can be Tungsten combustion achieved with ir pulse?
The MCU is send out the pulse to ir led strip, now generally used the integrated receiver,it has been the pulse signal amplification, detection, filtering out the original encoded signal to restore the original encoder pulse signal frequency,in generally the original code is very low frequency pulse signal from MCU, need to use the 38K pulse modulation when When transmission of pulse, the modulated waveform is the result of multiplying the two pulses，
can also be done with the 38K pulse train input signal by a non-goalkeeper coding,the tungsten lamp is no ordinary direct drive, the reaction speed is not up to the requirements (due to high frequency signal receiving head, the relay operation a lot of inertia,the Relay not to do that Continuous and Quick work。but has been energized until there is no signal.The idea is a good one in theory ,but the condition that the average voltage of the signal can reach the relay minimum operating voltage.) I used to drive the laser tube with ir pulses, the effect is very good.

How to use the infrared detector to verify bill authenticity?
We will explain this with led infrared. the bank staff has to painstakingly recount all of the bills and notes by photoelectric switch sensor of money counter. infrared penetration of the working principle is used a fixed wavelength of invisible infrared light, They penetrate the notes, receives the remainder of the ir led strip‘ light is carries on the analysis in view of the characteristics of the banknote paper and cover printing ink by the opposite receiver device.Then compare and contrast them with standard of value. The advantage of banknote is relatively strong,higher density and higher with gravure printing ink thickness,and thus the ability to absorb infrared signals to identify strong genuine banknotes.

There are different infrared signal of absorptive capacity.

according to this principle can be achieved forgeries. It should be noted that the same color and thickness of the ink will cause the difference of infrared penetration. Therefore, the need for mathematical calculations and comparative analysis of the signal detected by the infrared penetration.

What is the most effectivemethodto control ir led strip
The infrared led with high efficiency of infrared radiation material (commonly used gallium arsenide) made of PN junction, the forward bias(the ir led strip 950nm as 3.0v) Injection current to the PN junction can stir up  Infrared light. the spectral power distribution for the center wavelength of 830 ~ 950nm. LED is the abbreviation of light emitting diode, the Performance feature is a positive temperature coefficient,the current ever more big , temperature ever more high. it’s easily get into a vicious cycle. And temperature ever more high, the current ever more big. LED infrared light power is related to infrared led current.but forward current over maximum ratings, infrared emission power performance suffers decreased.put it another way to explain(triadic relation),Emission current ever more small, the sensitivity ever more high ,Then transmit power ever morestrong.The radiation intensity of the infrared emission tube, depending on the distance from the optical axis and change,also varies with the light receiving element is different. The incident light is affected by the change of light components and infrared emitting tube distance.Basically light measurement is inversely proportional with the square of the distance(The distance of the control is proportional to the transmitted power),it’s a positive The different  character oflight device.when use the infrared to the control of controlled unit. the control distance move in proportional with Transmit power. In order to increase the control distance of infrared, infrared emission control working in pulsed mode,because the effective transmission distance of pulse light(PWM)and pulse peak current into positive ratio, just try to improve maximize peak (Ip)can increase the infrared transmitting distance. The method of improving peak(Ip) is to decrease the pulse duty cycle, put it another way to explain, the compressed pulse width （T）. Usually its use frequency in 300KHz or less.

What is the difference between the frequency of infrared and visible light?
What is the difference between the frequency of infrared(ir led strip) and visible light?Us to take exactly wavelength and explain all this. there are ir led 940nm & visible light 770～622nm.
Different wavelength of the electromagnetic wave. reflected in consciousness through sense organs is different by human.
770 ~ 622nm, the feeling is red;
622 ~ 597nm, orange;
597 ~ 577nm, yellow;
577 ~ 492nm, green;
492 ~ 455nm, indigo color;
455 ~ 350nm, purple
to infrared electromagnetic wave be anywhere from microwave and visible light,They are wavelength 760 nm to 1 mm,
Simply words: infrared wavelengths is long than the wavelength of visible light,visible light in the wavelength range about 360-800nm, and infrared wavelength range is wider than visible light, from about 900nm to tens of microns,belong to infrared. Of course,wavelength ever more long, frequency ever more lower!

The relationship between About IR led strip 940nm frequency and 38khz IR led strip 940nm frequency not in the infrared range?
Check the lectromagnetic spectrum

and infrared frequencies is above 3*10^11, also is 300GHZ frequencies above.but the infrared remote control frequency were 38kHz. this frequency is not within the infrared range? How is it?How to return a responsibility?The simplest and most intelligible answer to this question is infrared is a light, and light has wave-particle duality, that in itself can have wave infrared features,Since there are characteristics of waves, it has a periodic (frequency).with waves properties suited for high-tech applications，such as Infrared control. Reflection, it was said above,300GHZ should refer to this frequency. and 38KHZ carrier frequency is modulated infrared involving radio,, involves to the radio, I suggest an alternative strategy（infrared on-off time） to comprehend. infrared appear 13US, and then disappear 13US, again 13us, then disappear 13US. equivalent period 26us(that is the frequency for 38kHz). Only in this way integration of infrared receiving head can receive the signal,if deviation 38KHZ too much, can not receive a signal.

Strobe has been led panel biggest influence

referred to A strobe, the simplest definition refers to the
light fluctuates constantly in switching  period. In the United States, the current frequency as 60Hz,with this frequency  it is hard for Transmit AC.has kept its AC wave within a tight band. Those currents can cause wild voltage fluctuations. Therefore, may produce twice to supply frequency flicker, which is 120Hz.If no suitable electronic circuit, such as ballast, drive or power supply,
light source will be produce stroboscopic. doing this to get attention for other people. Of course there is no physical discomfort. stroboscopic actually is a problem. the lighting industry concern is strobe range that could cause neurological problems and affect job performance humans can detect less than 50 Hz strobe light, of course, there are some people noticed to 100Hz. About 3 to 70Hz low frequency strobe may cause high sensitive populations and These seizures occur, ranged from about 100 to 500Hz moderate strobe may lead to stroboscopic effect of indirect perception. In this case, the dynamic objects may behave as a series of static images.
that’s what dance hall wanted too. but it is dangerous for industrial sites.. For example, strobe will enable mobile gear or blade looks very slowly, or even still. At the same time, it is also to bring a series of negative effects for your health, such as headaches, eye fatigue, and physical and mental fatigue.

RGB lights strip can be divided into two categories,
namely: Colorful led strip and full color led strip, colorful led lights is refers to the whole led strip  in the display of the color has a total of seven, respectively is red, blue, green, white, purple, red, yellow,
, colorful lights by a dedicated controller to control the led strip color,
but not that many show way. So the effect is relatively simple, mainly in order to beat sound effects cannot realize the Full-color.Full-color led  strip and called Magic led lights strip, refers to any color can be achieved, in theory, be able to reach more than 30,000 kinds, can achieve a gradual, meteors, chase, windows, marquees and so on effect, mainly used in that outdoor lighting decoration, KTV decoration, decorative corridor, Patty decoration atmosphere and so on.There the led strip device was, with a control ic that it’s could  control work of led strip.generally have control IC: WS2811, WS2812, WS2821, WS2822.

Customers   ask the question of ir led strips Two days ago.  record them all. as follow:
I use the ir led, the control current as 30mA, facing the rear and close to the receiving tube, receiving no response (receiving pipe the output voltage does not have any reaction). With a remote control for his launch had response, which is why?Infrared emission must be in 38K carrier? In addition take series of infrared emission will reduce lifetime of the infrared transmitting tube, right?

In order to avoid the interference of other infrared signals（There are infrared everywhere）, Their shocking conclusion: almost every practical infrared remote control equipment had carrier signal.radio remote control equipment is also the case.

So use ready-made set of remote control device, if the transmitted signal does not meet the communication requirements (such as carrier frequency), the receiving device will not respond.Mentionof the “38K reception” should be the receiving device (receiver)only interested （work）in 38K carrier.the emission of infrared frequency hasn’t been modulate of 38K carrier,the receiver device certainly can’t work.Otherwise, the receiving device is not ideal that about anti-jamming capability,
the Carrier frequency does not necessarily is 38K, a lot of remote control using a 455K modulation,when you open the cover of TV remote control which you can see the 455K ceramic filter, which is the remote control of the carrier frequency.

LED light bar of the high-speed development era
In recent years, LED technology has been a new breakthrough, which provides a solid technical support for the development of LED lamps and other lighting products. In recent years,some local governments have attached great importance to the development of LED industry, the development industry and Innovation（ex,Recent our production 4 in 1 rgbw led strip）is more prosperous side for LED light bar.According to relevant expertise, five years later, incandescent lamp will be fully eliminated, is its never been able to crack the problem about energy-saving lamps contained mercury pollution to the environment, also do not have the development potential, therefore, LED lighting will hold live market in the future, and the technology of LED strip more mature, the scope of application is wider and will be more people to accept.There are has 4 watt LED light strip, 1000 hours consumes only 4 degrees.the mall lighting 10 hours a day on that count, three months down each led strip about with 4 degrees of electricity in three moths, this effect is not energy-saving lamps can be compared. More power saving, high brightness, coupled with the reasonable price, making for happy clientsOur retail distributors say:”The purchase of energy-efficient lighting products more likely to choose environmentally friendly products, consumers have been increasing.”Over the past 10 years, LED light bar increased each year, at present light efficiency of LED lamp strip has exceeded the traditional light source and the overall cost is less than the incandescent lamps, halogen spotlights and CFL downlights,

Opportunities and challenges of development are peers, business opportunities and risksare always co-existed. And the development of LED strip, it is often a long time.Edison invented the light bulb has more than a hundred years, but in this long period, That advantage of low cost has helped light bulb  become the leader in the advantages the lighting market. Before the emergence of energy-saving lamps,
the shows that beginning of the second generation of lighting products to dominate the market, and now 90% of lighting using energy-saving fluorescent lamps. History fluorescent lamp has for several years, The fluorescent light has been good use for several years, and then arrived at the third generation of light source. In fact, it has quietly entered our life, it‘s the LED lights strip.In this environmentally friendly and energy-efficient world, LED strips is a good choice for. The LED strip will become the third generation of human light source. But the price is a big obstacle, when prices fell, LED lamps can replace energy-saving fluorescent lamp,
can lower price only and  stable product quality, LED light bar to take energy-saving fluorescent lamps on the market. LED light strip in order to enter the average consumer household,
First,it is necessary to improve the luminous efficiency and Innovation（ex,Recent our production 4 in 1 rgbw led strip）.Second is to solve the heat problem,Because of the high power LEDask heat dissipate for having exacting standards, the environmental of temperature up to a certain degree will produce decay, resulting in reduced LED life（server time）.Only to solve the problem of heat dissipation. Finally, to reduce the price of LED, since the price is the key factor that directly affect their popularity rate.
