LED detection process, First, eliminate false faults. The intermittent flash after turning off the light is not the quality of the light. Main reason is electrical circuit installation is not standard, set the switch in zero line to cause. As long as the incoming line end and live wire exchange can be. Use a neon switch, which can still form a micro circulation circuit after turning off the lamp, or install a double switch by borrowing a line, which may cause flash after turning off the lamp. When repairing LED energy-saving lamps, measures should be taken for safety application: isolation transformer isolation mains. Secondly, LED energy-saving lamps can not be normally lit maintenance: LED energy-saving lamps have obvious damage to the maintenance of components.

Protection grade, IP protection grade is the lamps and lanterns is according the characteristic of the dust, prevent moisture to classification, composed of two Numbers, the first number represents the level of dust, prevent the outside shooting of lamps and lanterns (0-6), the second number represents moisture proof, waterproof lamps and lanterns of shooting the sealing degree (0 to 8), the greater the number said the higher degree of protection. Synchronization is the basic requirements of LED lights to achieve coordinated changes.

Therefore, the filament is easily fused at the moment of turning on the lamp, which also doomed the “short life” of the incandescent lamp - the service life is generally about 1000 hours. Leds, known as “Light Emitting Diodes”, are a type of semiconductor called light-emitting diodes (leds) and the true “unsung heroes” of the electronics world. LED CFLS work in a similar way to lasers, with lots of electrons orbiting around the nucleus, Moving at high speed, unstable atoms in the ground state release energy in the form of photons.

King Kong said engineers must concentrate on the big LED screen to ensure quick reaction and timely treatment in case of bad spots, collisions and other accidents on the screen, and cannot enjoy the normal process of the game. King Kong tends to rush to the next arena immediately after a game. Riad LED screens on buildings in Doha, It is understood that the host country of this World Cup Qatar is located in the middle of the west coast of the Persian Gulf, a tropical desert climate, hot and dry, humid coast.

The LED chip is the core of the LED device, and its reliability determines the life and luminous performance of the LED device and even the LED display. The cost of LED chips accounts for the total cost of LED devices is also very large. With the reduction of costs, LED chip size cutting is getting smaller and smaller, but also brings a series of reliability problems. Bond wire, bond wire is one of the key materials of LED packaging, its function is to realize the electrical connection between the chip and the pin, and plays the role of current import and export between the chip and the outside world.
