However, it's important to consider a few factors before making this modification. First, the material and shape of the dome lens will affect the light output and beam angle. Different materials have different refractive indices, which will change the way the light is refracted and focused. Additionally, the shape of the lens (e.g., flat, convex, concave) will also affect the beam pattern and spread. Adding an extra dome lens to the 2835 SMD LED red LED( 625nm LED or 635nm LED ) can potentially improve its light output and focusing properties. However, it's crucial to carefully consider the factors mentioned above to ensure that the modification meets the specific requirements of the application. If the dome lens of Domed LEDs has a 90-degree angle, it will cause the light emitted from the 2835 SMD LED Red SMD LED to be projected in a more focused and narrower beam pattern. This means that the light will be concentrated in a smaller area, resulting in a brighter, more intense spot of light. One advantage of using a 90-degree dome lens is that it can be useful for applications where you need to illuminate a specific area or object and want to avoid the light spilling over into unwanted areas. It can also be useful for creating a clear, defined boundary or line of light. It's important to carefully consider the specific requirements of your application when choosing a lens angle. If you require a focused beam of light, a 90-degree dome lens may be suitable. However, if you need a more diffuse or uniform lighting effect, you may want to consider a different lens angle or type.

  • Is 940nm LED Eye Safe?
    940nm LED can be package with SMD LED type and LED Lamps type. But during the application, the light of IR LED in 940nm wavelength is safe? The safety of 940 nm (nanometer) wavelength, commonly used in infrared (IR) light-emitting diodes (LEDs) and lasers, is a topic of concern and interest, particularly regarding its impact on human eyes. To determine whether 940 nm is eye-safe, it is crucial to understand the nature of this wavelength, its interaction with the eye, and the safety standards associated with it. Infrared light falls within the electromagnetic spectrum, with wavelengths longer than those of visible light. The human eye is sensitive to wavelengths ranging from approximately 400nm LED wavelength (violet) to 730nm LED wavelength (red). Beyond this range, light becomes invisible to the naked eye. However, this does not mean that it cannot affect ocular tissues. The potential harm caused by exposure to infrared radiation depends on various factors such as wavelength, power density, exposure duration, and the sensitivity of ocular tissues to the specific wavelength. In the case of 940 nm, it is generally considered to be eye-safe under normal operating conditions. The primary reason for the eye safety of 940 nm is its relatively low absorption by the cornea, lens, and retina. The cornea, being the outermost layer of the eye, acts as a protective barrier against foreign objects and excessive light. It absorbs most of the UV light and a significant portion of shorter wavelength visible light, but it is relatively transparent to 940 nm infrared light. Similarly, the lens, located behind the cornea, absorbs UV light and some visible light, but it is also relatively transparent to infrared light, including 940 nm. The retina, which is the light-sensitive tissue at the back of the eye, is the most critical concern when it comes to eye safety. However, at 940 nm, the retina is also relatively insensitive, reducing the risk of damage. It is important to note that while 940 nm is considered eye-safe under normal operating conditions, prolonged or intense exposure to this wavelength can still cause harm. The International Electrotechnical Commission (IEC) has established safety standards to ensure the safe use of lasers and other sources of optical radiation, including infrared. According to the IEC 60825-1 standard, lasers emitting at 940 nm fall into Class 1 or Class 1M, depending on the power output. Class 1 lasers are considered safe under all conditions of normal use, including prolonged viewing, while Class 1M lasers are safe when viewed with optical instruments (such as magnifying glasses) but may pose a risk if viewed directly with the naked eye. The IEC standards also define exposure limits, specifying the maximum permissible exposure (MPE) for different wavelengths and durations. These limits are based on extensive research and take into account the potential for both thermal and photochemical damage to ocular tissues. To ensure eye safety, manufacturers of devices that emit 940 nm infrared light, such as IR LEDs and laser diodes, must adhere to these safety standards. They incorporate appropriate safety features, such as beam divergence, power limitations, and optical filters, to minimize the risk of eye damage. In conclusion, 940 nm infrared light is generally considered eye-safe under normal operating conditions. Its relatively low absorption by ocular tissues, particularly the cornea, lens, and retina, reduces the risk of damage. However, adherence to safety standards, such as those established by the IEC, is crucial to ensure safe use and prevent any potential harm associated with prolonged or intense exposure to this wavelength.

    There are kinds of SMD LED and through-hole LED available in our factory. For some high power LED, we normally just produce it with SMD LED package type because that will make sure the LED can dispatching the extra heat during it's working(As we know, there will have extra heat while the LED working in the high operation current). And SMD LED type will got a better heating dispatching performance in this case. For high power LED, no matter the high power IR LED or high power colorful LED. The main size is 3535 SMD LED type, 5050 SMD LED type or 8mm SMD LED type. In this case, we going to discuss about the 8mm SMD LED type. There will have a dome lens on the top of SMD LED. A dome lens placed on top of an LED can diffuse and scatter the light emitted by the LED, creating a more even and wider distribution of light. But for some high power LED, the dome lens cannot handle the high temperature. Which means the dome lens will be melted during the reflow soldering machine. It will be the picture as follow: This can cause a number of issues, including: 1. Reduced light output: The dome lens is designed to focus and direct the light emitted by the LED. Without the lens, the light will be dispersed in all directions, resulting in reduced brightness and efficiency. 2. Color shift: The dome lens is also responsible for filtering and shaping the light emitted by the LED. When it is melted, the color temperature and spectral distribution of the light can be altered, resulting in a different color appearance. 3. Damage to the LED: The high temperatures used in reflow soldering can damage the LED itself, particularly if the lens is melted and the heat is not properly dissipated. To avoid these issues, it is important to use appropriate soldering techniques and equipment when working with high power LEDs. This may include using lower temperature soldering methods, such as hand soldering or hot air rework, or using specialized tools and fixtures to protect the dome lens during reflow soldering. In order to make things better, the dome lens high power LED that can handle high temperature are also available in our factory now. When you need this high power LED to work good during the reflow soldering, just let us know then we will offer the correct product for your test.

  • What is IR Receiver Diode
    An IR (infrared) receiver diode is a component used to detect infrared signals that emits by IR LED, such as 940nm LED, 850nm LED or even some other far red infrared LED like 1050nm LED, 1200nm LED 1550nm LED ect. It is a type of photodiode that converts the infrared light into an electrical signal. IR receiver diodes are commonly used in remote control systems, where they receive signals from a remote control and convert them into electrical signals that can be processed by the device being controlled. They are also used in security systems, where they detect the presence of people or objects based on their heat signatures. To make the IR receiver diode work, you need to follow these steps: 1. Choose the right IR receiver diode based on your project requirements. 2. Connect the IR receiver diode to a power source, such as a battery or power supply. 3. Connect the output pin of the IR receiver diode to a microcontroller or other circuitry that can process the received signal. 4. Use an IR remote control to send signals to the IR receiver diode. 5. The IR receiver diode will detect the IR signals and convert them into electrical signals that can be processed by the microcontroller or other circuitry. 6. Program the microcontroller or other circuitry to respond to the received signals in the desired way, such as turning on a light or controlling a motor. 7. Test the IR receiver diode and adjust the circuitry as needed to ensure proper functionality.

  • How to test IR LED?
    IR LED can be package as SMD LED type or Through-hole LED Lamps type. Such as 5mm IR LED, 3mm IR LED or 2835 SMD LED, 5050 SMD LED ect. To test an IR LED, for all the surface mount diode and DIP LED, we can follow these steps: 1. Connect the IR LED to a power source: Connect the positive leg of the IR LED to the positive terminal of a battery or power supply and the negative leg to the negative terminal. There will have a polarity mark on the infrared LED. When we check with SMD type, then it's the gap side of pins and it will be the longer or shorter pin when we check with DIP LED. 2. Use a multimeter: Set the multimeter to the diode test mode. Place the probes on the legs of the IR LED. If the LED is working, the multimeter will show a voltage drop. 3. Use a smartphone camera: Different with those colorful LED, infrared LED are normally invisible. In this case, we can use some tool that in our hands, which is the cell phone! Open the camera app on your smartphone and point the IR LED towards the camera lens. If the LED is working, you will see a faint purple glow on the screen. 4. Use an IR receiver: Connect an IR receiver to a microcontroller and program it to detect the IR signal. Point the IR LED towards the IR receiver and see if the microcontroller detects the signal. 5. Use an oscilloscope: Connect the IR LED to an oscilloscope and observe the waveform. If the LED is working, you will see a square wave with a frequency.

  • How come the Pink & White Bipolar LED are not available in DIP LED type?
    Bipolar LED means those DIP LED(through-hole LED) that with two pins and two colors, which can be 5mm LED, 3mm LED or retangular LED, oval LED ect. The emitting color of LED depends on the LED chip inside normally. In order to produce the bipolar LED that emits two different color, we need to put two kinds of chip inside the same cup. For some chip, we can change it`s emitting color by the phosphor(liquid). Different phosphor will make different emitting color. For example, when we need the warm white color, we need to put the yellow phosphor on the top of blue chip. And when we need the pink emitting color, we need to put the pink phosphor on the top of blue chip. If we just need single color in the same LED Lamps, phosphor will work perfect in that case. But when we need two color in the same through-hole LED, which means we need to put two chips inside the cup and put two kinds of phosphor inside. It`s OK to put two chip inside the same cup, but the phosphor will mix together due to the phosphor is liquid. When we put red phosphor and yellow phosphor together, we will get orange phosphor at the end...then the phosphor will cover both of blue chip inside and emits the same color when we light it up. But this bi-color LED with pink & white color do available in SMD LED type, because there have two cups inside of SMD LED case, which ensures that the two types of phosphor can act separately on the two chips.

  • Brightness of 5mm LED or dome lens SMD LED
    There are different viewing angle in 5mm LED, 3mm LED, 8mm LED or 10mm LED. During the production, we will control the viewing angle by putting the LED frame deep into the mould of epoxy lens. We will get wider viewing angle when we make the LED frame more close to the top of LED lens. The common angle can be 15 dgeree, 30 degree, 45 degree, 60 degree and 90 degree. If we need to get wider viewing angle then that, we can use the 5mm straw hat shape of size to arrange the production; Dome lenses can affect the brightness of LED lights by changing the direction and distribution of the light. When a dome lens is placed over an LED, it can help to focus the light in a specific direction or spread it out more evenly. The shape and material of the dome lens can also affect the amount of light that is reflected or absorbed, which can impact the overall brightness of the LED. Additionally, the size and shape of the LED itself can also play a role in determining the brightness of the light. In all these discussions, the viewing angle of LED(or the dome lens on the top of SMD LED) only affects the "mcd" value of the LED, not the LM value. The "mcd" value is the brightness value of the brightest point at the center of the vertex of the lens. The more scattered the light, the less brightness it will reach the center point, so the larger the angle, the lower the "mcd" value. The LM value is the overall luminous value of the LED chip, which is only affected by the chip size and operating current
