LED light generated when the heat can not be derived, will make the LED junction temperature is too high, affecting the product life cycle, luminous efficiency, stability. LED heat dissipation: According to different packaging technology, cooling methods are different, and a variety of LED cooling method can be the next schematic: Cooling Path Description: (1) Heat from the air (2). Heat is exported directly from Systemcircuitboard (3). Derived heat from the gold wire (4). If eutectic and Flipchip process, thermal energy will be through the through-hole to the system circuit board and export LED die (Die) to gold, eutectic or flip chip connected to its substrate (SubstrateofLEDDie) to form a LED chip (chip), and then the LED chip fixed to the system board (Systemcircuitboard). Therefore, the possible cooling path of the LED is to heat directly from the air, or through the LED crystal substrate to the system circuit...

LED filament is also called LED lamp post. In the past LED light source to achieve a certain degree of light intensity and light area,that need to install the lens and the like optical devices and will affecting the lighting effect, reduce the energy saving. LED filament is 360 ° full angle Luminous, large angle light and without lens, achieving three-dimensional light source, bringing unprecedented lighting experience. 1,360 ° light angle. 2, integrated high-voltage drive, the power factor to maximize power, lighting costs to minimize. 3, high-quality light source, color rendering index of 90 or more, light efficiency 110lm / W or more. 4, with a transparent substrate material with a new 360 ° molding packaging process. 5, fluorescent glue molding process, good quality. 6, the new light vision, feel the original ecology of the "incandescent" light environment. LED filament can be used in crystal chandeliers, candle lights, bulb lights, w...
Yunsun LED is a manufaturer of indoor LED lighting. Candle bulb is one of these popular bulb. 4W/5W led candle bulb is available, that equival 35w-50 incandescent. COB light source, the led we used is Epistar. from Taiwan 0-100% dimmable. The dimming IC driver is NXP from Philips, matched with leading and trailing edge traic dimmers. Yunsun LED has international patented lens : three finger lens. Its function is make the beam angle wider. "Quality is culture" that is Yunsun LED brand!
First, the voltage and current 1. Do not recommend the use of LED in parallel, because even the same model, the same batch of LED operating voltage has a certain difference, unless the current circuit. 2. In the installation of ultra-bright white LED, there must be anti-static facilities, because the electrostatic damage to the ultra-bright white LED even if the naked eye can not see, will reduce the service life. 3. If the LED operating voltage changes 0.1V, then the working current may change about 20mA. Under normal circumstances the use of series current limiting resistor, you can also use a simple constant voltage circuit, the purpose is to do automatic pressure limiting current limiting, to prevent damage to the LED. 4. The peak current of ordinary LED is 50 ~ 100mA, the reverse voltage is about 6V. When applying LED, pay attention to the design of the circuit when the peak voltage and current do not exceed this limit. (Ex...
Yunsun LED recently launched some new LED light. One is this RGB wireless book lamp: Wireless & Rechargeable: Powered by Li Battery inside which can support the lamp for 5-6 hours. Recharge it by connecting the power charge wire to your computer or your mobile power adaptor USB port. Magic Light Color Changeable: Switching the light color by open and close the book light, Warm White, Blue, Red and Green 4 Color Options, Warm White Color for regular lighting, Blue Light gives great help to people to get into sleep. Magnet Holding Design: Has Magnet in both top and bottom covers, which enables the book can be shaped as round and half circle,can be placed on your table, desk as reading light, or stick onto your refrigerator or magnetic wall as night light. Portable and Foldable: Foldable as an old book,which enable it to be portable as a note book, can be easily put into your hand bag and briefcase, very light, no more th...
1, ceiling openings Household downlight cut hole is 2-inch, 2.5-inch, 3-inch ,the larger the size of the hole, the overall height of the overall height of the downlight, the greater the requirements of the depth of the ceiling. In general, the full length of the downlight after the extension of 10 cm to 13 cm between the ceiling, so the depth of the installation ceiling ceiling ceiling generally above 13 cm, if the ceiling is too shallow, you can consider the installation of ceiling light or horizontal Downlight. While the ceiling light installation ceiling as long as 6 to 8 cm. 2, light source 3, light efficiency requirements 4, the price From the price point of view the same grade, spotlights to be more expensive. Downlight has horizontal and vertical insert two, horizontal insert price than the vertical insert a little expensive (but also the same material). 5, the risk Generally speaking, the lamp is more safe than the spotlights, the general spotl...
LED lighting products have broad market prospects, especially in the lighting field. Currently used in lighting the field of LED products are more, such as LED guardrail lights, LED Caoping Deng, LED spotlights, LED underwater lights, LED buried lights and so on. Although we are more understanding of LED light source with energy saving, long life, no radiation (environmental light source) and other advantages, but with LED products related to several key issues also need attention. : First, the use of DC constant current power supply LED products to use a dedicated switching power supply (constant current source) to the LED product power supply this will not affect the product life, but the product cost is relatively high. Second, to do anti-static measures Different quality standards of LED products, anti-static aspects of the capacity are not the same, so LED products in the processing of the production process to adopt...
LED Downlight is a kind of embedded in the ceiling under the light of the lighting type of lighting. It is the biggest feature is to maintain the overall unity of the building decoration and perfect, not because of the setting of the lamp and destroy the perfect unity of the ceiling art. Recessed Downlight the structural advantages of the light source is hidden inside the building decoration, the light is not exposed, no glare, people's visual effects are soft and uniform. Generally in the hotel, family, cafes use more. From the direction of the light source, the downlight is a directional lighting, only its opposite surface can be received, the beam angle is focused, the light is more concentrated, bright and dark contrast. More prominent by the object, high luminosity, but also bring out a quiet atmosphere of the environment. Generally suitable for shopping malls supermarkets, office buildings, business hall. From the way to the lighting points, which...
