The Composition And Application Of LED Light Box

The composition and application of LED Light Box
LED Light Box using light guide plate formed by the backlight module, a combination of a variety of frame material made of a multi-functional new advertising advertising carrier. Than the traditional light box to save about 76% -89%, brightness, shape, ultra-thin, compared with the traditional light box, light guide plate LED Light Box with beautiful, energy saving, environmental protection, security and other advantages. Shape a single card, double-sided cards, arc cards and signs, and so on.
LED Light Box beautiful, elegant appearance generous. Its thickness is generally less than 3CM, only the thickness of ordinary light box nearly 1/10, to maximize the space utilization, beautify the environment, saving transportation costs, simplifying the installation process, broaden the scope of application.
In the use of space demanding environment such as: elevator, public access, shopping malls, supermarkets, subways, stations, etc., is the best use of LED Light Box.
LED Light Box tester, with high-precision digital display, high precision, clear display, resistance ratio more scientific, reasonable, fast, balanced, greatly improving the LED Light Box LED life, and reduce the failure rate of finished products. Using high-voltage power supply isolation control technology, the tester output voltage to zero, the use of safe and reliable. Main use: This tester is mainly used for LED Light Box, large LED Light Box neon signs, LED Light Box luminous characters, LED Light Box and other products in the current limiting resistor configuration, troubleshooting and leakage point detection. Product features introduced 1. Leakage detection: At present, most of the light box with double-sided aluminum-plastic plate perforated lamp method, so aluminum-plastic plate burr or lamp foot touch board will cause light box leakage, in the hundreds of thousands of lights feet To find out the leakage point is the producer of a headache. QQ-II tag type (second generation safety type) LED Light Box tester special increase this feature, so that the fault detection is convenient, the product is more secure. As the QQ-II light box tester using high-voltage power supply isolation control technology, the tester output voltage to zero, accidentally touch any output are safe and reliable, which is simple tester can not do 2. Troubleshooting: the past, we use a multimeter to troubleshoot, from hundreds of light tube to find the problem is extremely inefficient, the use of LED Light Box electronic LED Light Box light box tester group, sub-flow detection, fast, efficient and save time. 3. Configuration resistance: As the different manufacturers of light-emitting diode chip different internal resistance and voltage are not the same, in fact, there is no precise current limiting ratio conversion method, such as: red tube voltage 1.8 ~ 2.2 volts, single work The pressure range is very small, but dozens of connected in series use, the pressure will reach tens of volts, the current deviation is great, the use of QQ-II LED Light Box electronic light box tester can fundamentally solve the problem.
LED Light Box in the LED Light Box chip is a large heat flux density of electronic components, they are in the process of running, due to its static and dynamic loss, resulting in excess heat through the cooling system to the outside of the entire LED Light Box to maintain its stable working temperature The LED Light Box at present the luminous efficiency is not very high, causing temperature rise, life expectancy. In order to reduce the junction temperature to improve life expectancy must pay great attention to the problem of heat. LED Light Box cooling design must start from the chip until the entire radiator, every link should be given full attention. Any one part of the design will cause serious heat problems. So the design of the heat must be given full attention.
High-performance micro-slot group composite phase change heat transfer technology to meet the high-power LED Light Box lighting requirements, the technology named "micro-slot group composite phase change integrated cooling technology." The technology has been successfully applied LED Light Box lights, LED Light Box chip heat can be instantly distributed in the entire cooling space, extending the LED Light Box lamp life to improve the luminous efficiency.
First, micro-slot group composite phase change integrated cooling technology:
LED Light Box chip generated by the heat is always the final through the lamp shell to the air. Common heat is: LED Light Box chip heat generated from its metal heat block out, first through the solder to the aluminum substrate pcb, and then through the thermal plastic to the aluminum radiator. LED Light Box lamp cooling in fact, including heat and heat two parts. There is a concept to first clear, that is, the difference between heat and heat. Heat conduction is to heat the fastest from the heat source to the radiator surface, and heat is to heat from the radiator surface to the air. First of all to heat the fastest lead, and then to the most effective to the air to go. The heat sink of the traditional heat sink is the aluminum fin, our heat sink is: micro slot group phase change technology.
