The structure of LED is sturdy and not easily affected by vibration, and the light output brightness will not decrease significantly during use.Besides, we can’t ignore. led strobe warning lights It has injected new vitality into the development of the industry and has far-reaching significance for activating the market. https://www.lkx-mascarello.com

　　LED car lights are suitable for various lighting applications in automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signals, daytime running lights, pedal lights, instrument lights, license plate lights, door lights, interior lights, width lights, navigation, entertainment systems, backlights and indicator lights. Compared with traditional light sources, LED light sources have large differences in physical size, luminous flux, spectrum, and spatial distribution of light intensity. Therefore, LED detection cannot replicate the standards and methods of traditional light source detection.

　　What Are the Most Common Detection Technologies for LED Headlights?

　　Detection of optical parameters of LED lamps

　　1. Luminous intensity detection

　　Light intensity is the strength of light, which is the amount of radiated light within a certain angle range. Since LED light is relatively concentrated, the inverse square law does not apply at close distances. Therefore, the CIE127 standard stipulates that the conditions for measuring light intensity are A (far-field conditions) and B (near-field conditions) for measuring the average normal light intensity. The detector area for both conditions is 1cm2. Generally, standard condition B is used to measure luminous intensity.

　　2. Luminous flux and light efficiency detection

　　Luminous flux is a physical quantity that measures the total amount of light emitted by a light source. It represents the sum of the light energy emitted by the light source in all directions. There are two main methods for detecting luminous flux:

　　Integral method: Light the standard lamp and the lamp under test in the integrating sphere in turn, and record their readings on the photoelectric converter as Es and ED respectively. The luminous flux of the standard lamp is known as Φs, then the luminous flux of the lamp under test ΦDED〜Φs/Es. The integral method uses the principle of “point light source” and is simple to operate, but it is affected by the color temperature deviation between the standard lamp and the lamp under test, and the measurement error is large.

　　Spectrophotometry: This method calculates the luminous flux by measuring the spectral energy distribution of the light source \( P(\lambda) \). Use a monochromator to measure the spectral energy of the standard lamp in the wavelength range of 380nm to 780nm on an integrating sphere, and then measure the spectral energy of the lamp under test under the same conditions. By integrating these spectral energy values, the luminous flux of the lamp under test can be obtained.

　　Luminous efficiency is a parameter that describes the efficiency of a light source. It is defined as the ratio of the luminous flux emitted by the light source to the electrical power it consumes. For LED light sources, constant current is usually used to measure luminous efficiency to ensure the accuracy and repeatability of the measurement.

　　”Big bags, small bags, please go through security check!” Security check is always an essential step when you travel by high-speed rail, airplane, or subway. I wonder if you have ever been interested in this security check machine. What can the staff see on the screen? How do they quickly identify the items in the suitcase? Today, let the editor reveal this secret for you.In combination with these conditions, security screening machine It can still let us see good development and bring fresh vitality to the whole market. https://secuzoan.com/

　　security check

　　How does the security inspection machine work?

　　Generally speaking, the machine that conveys and inspects luggage is called an X-ray luggage inspection machine. As the name suggests, the security inspection machine uses X-rays to inspect luggage.

　　X-rays are short-wavelength electromagnetic waves that can penetrate objects. The penetration of X-rays varies depending on the thickness, density and material of the object.

　　Everyone should know that X-rays in hospitals are also used by doctors. The penetration rate of X-rays varies according to the density of the structure and tissue. The penetration rate is high in loose areas and low in dense areas. The bones of the human body are denser than the skin and flesh tissue. Therefore, when X-rays are irradiated to the human body, the outline of the bones will be displayed more clearly on the screen.

　　security check

　　The same is true for the security inspection machine that checks luggage. The penetration rate of X-rays on different objects is different. When the suitcase passes through the security inspection machine, the X-rays penetrate the suitcase and display the outlines of different objects on the display screen.

　　At this time, some friends may feel confused: X-ray imaging should be black and white, so why can security inspectors identify different objects so quickly?

　　This question really hits the nail on the head. If you have ever looked at the security check display screen, you will find that the image on it is in color, not black and white.

　　security check

　　Normally, the color of the image formed by X-rays on the film is indeed black and white, just like the X-ray photos in the hospital. The reason why a color image appears on the security screen is that the computer calculates and converts the projection intensity of the X-rays. This is also to make it easier for security personnel to quickly distinguish different objects in a short period of time.

　　Normally, orange represents organic matter such as liquids and sprays; blue represents metals and various controlled knives; and heavy metals or lead, which can completely absorb X-rays, will be displayed in black.

　　Now you should know why the staff will immediately notice and ask you to take out a small pair of scissors in your suitcase; and the water in your backpack will also be asked to take out and drink a sip.

　　The data shows that, wired PIR motion sensor Its development potential should not be underestimated, and it is also the inevitability of its existence. https://www.sunlit-tech.com

　　PIR sensor (Passive Infrared Sensor) is a passive infrared sensor. It is widely used in consumer products such as doorbells, cat eyes, induction switches, night lights, and security because of its low power consumption, low price, and simple use.

　　(1) PIR detection principle

　　PIR also has another alias, which is pyroelectric infrared sensor. Its detection principle is the pyroelectric effect, that is, the phenomenon that a substance will generate electric charge when the temperature changes. The normal human body temperature is 36-37 degrees, and the infrared radiation released is about 9-10um. The detection wavelength range of pir motion detector is generally in the range of 5-14um. That is, within the detection range of PIR, if there is an energy change of 5-14um wavelength, the PIR sensor will generate a current change, thereby giving a trigger signal. It should be noted here that PIR detects energy changes, not infrared radiation of a fixed wavelength. If an object with a fixed wavelength is not moving, PIR will not detect it.

　　(2) Advantages of PIR

　　Low power consumption, typical power consumption is about 10uA

　　Low price, ranging from one or two yuan to five or six yuan

　　Easy to use, the simplest one only needs to detect a pin level signal

　　(3) PIR classification

　　There are many types of PIR motion detector, which can be roughly divided into the following ways:

　　Enablement controllable: switchable PIR

　　Output signal type: digital PIR and analog PIR

　　Is the sensitivity adjustable: adjustable PIR and non-adjustable PIR

　　Sensitivity adjustment method: hardware adjustment and software programming adjustment PIR

　　(4) PIR selection

　　When selecting a PIR sensor, we generally need to consider the following basic requirements: voltage range, operating current, number of pins required, data output format, whether the sensitivity is adjustable, structural package size, and compatibility with the Fresnel lens. Another important consideration is cost. Without considering cost, it doesn¨t matter whether you choose a model or not. Just choose the best one. In actual product development, especially for consumer products, prices are very sensitive. Basically, all bosses want to use the cheapest device and debug it to achieve the best effect, especially for products with large shipments. If you don¨t have high requirements for product quality, it doesn¨t matter. If you have strict requirements for product quality and performance, you need to be very careful when selecting a model to avoid replacing the device when you find that it does not meet the requirements in the later stages of the project.
