Problem of Infrared emission

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.
Oscilloscope show 38k
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.

Opportunities and Challenges for development of LED strip

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.

Quality of infrared light(strips & emitting diodes)

Judging the quality of infrared light strips  & infrared light emitting diodes as same with judgment of ordinary diode.  the infrared light emitting diodes emitting power is about 100mW. Luminous efficiency of infrared light emitting diode with a special instrument for determination, and amateur conditions, can rely on the experience with the roughly distance determination method. The infrared receiving tube receiving circuit is a photosensitive diode,  infrared receiving diode reverse bias need bias voltage be good for work and obtain high sensitivity.
How it works about infrared control system?
Actually it’s infrared photosensitive resistance. The supply voltage is small in ultra low resistance state when infrared irradiation is waked. the other way round:supply voltage is big when infrared after light off in a high impedance state is close to the 6K, a big portion of the whole, general points to more than 4V is no problem. In generally The infrared receiving diode are rotundityr and quadrate two types. Because the transmitting power of the infrared light emitting diodes are small, weak signal received by the infrared receiving diode, so the receiver will increase the high gain amplifier circuit. But now it is amateur or formal products, mostly by product integrated receiver,  Integration of infrared receiving head is a set of infrared receiving, amplifying, filtering and comparator output module, it’s stable performance, reliable. So, with integrated receiver module, user no longer make a receiving amplifying circuit, so the infrared receiving circuit is not only simple but also greatly improved the reliability .

Test report of Infrared emitting and receiving

Test report of Infrared emitting and receiving
First:The principle of infrared, infrared remote control has been widely used in home appliances and industrial control system,
need realize one important thing that work principle and performance, also is not difficult.

*Characteristic of  infrared :eye can see the visible light wavelength,
arranging wavelength in color sequence;  red, orange, yellow, green, cyan, blue, purple, respectively The red light in the wavelength range as 0.62μm ~ 0.76μm, more longer than the red wavelength light is infrared. The infrared ray To exhibit similarity with ir led strips.

*Application: Infrared remote control is the use of 0.76μ m~1.5μ m  wavelength(near infrared)to transmit a control signal. feature of Infrared is that it does not interfere with other electrical equipment work, it will not affect the surrounding environment. Circuit is simple,
coding for transmitted signal can realize the function of multi-channel infrared remote control.Secode: divide the infrared remote control system into receive model and emitting model. The emission component parts as infrared emitting diode, the emits infrared as visible light, Common infrared infrared wavelengths emitted from the light emitting diode is about 940nm,the shape is the same with φ 5 mm light emitting diode, but different colours. In general there are transparent, black and dark blue three type.

Optical components of UV roughly sensor

In order to ensure the photon detection in the solar blind region, the design work of optical receiving and conversion has several important links need to carefully .

First, as the ultraviolet optical system in front of the sensor, in view of the ultraviolet lamp band  or ultraviolet led strip is special,The work of design requires special consideration.

Second, the UV lamp filter is blind and realize photon detection portal, Big enough to consider that maximum suppression of background and the maximum signal via tradeoffs. Since the optical receiving surface is large, the molding.requirements is low than band rough filter radiation suppression.

Contributes to plant growth with LED plant light

With the continuous updating of science and technology of agricultural equipment to improve,
agricultural lamp current is no longer simple to fill, but there is help plants grow better, so it euphemistically known as grow lights.In the previous products, almost all agricultural lights are visible light becomes special fill light for plants, and in the natural lack of ambient light to light supplement, to finish time of plant illumination. And now the plant growth lamp, we have found the best availablelight band as a light source,our LED ( ultraviolet led strip)grow light sources used are: red wavelength 620-660nm, blue wavelength 450-470nm, violet wavelengths 410 -420nm, orange light wavelength 600-610nm.
According to the different plants to suitable ratio of the light source, which makes it possible for plants in the fill process were fully photosynthesis,This technique allows the Stem and leaf to grow faster and stronger. It’s a major breakthroughfor increase production played a major role in upgrading. Therefore, our plant is also known as plant growth lamp lights.
