Stage lighting installation seven major considerations analysis
Stage lighting is one of the many forms of stage art. It uses stage lighting equipment (such as lighting fixtures, slides, control systems, etc.) and technical means. With the development of plots, the display environment, rendering atmosphere and highlights are highlighted by light colors and their changes. The central figure creates sense of space and time in the stage, shaping the external image of the stage performance and providing necessary lighting effects.
Stage Lighting Installation Seven Notices
The current mainstream entertainment venues, such as KTV, bars, nightclubs and other places of decoration design are inseparable from the LED lighting equipment, corresponding to the national economy is the level of improvement, the continuous improvement of people's cultural taste, the proportion of stage design in the entire performance of the more The heavier it is. In the following, the author will introduce seven issues that we should pay special attention to when installing LED lighting equipment in the early stage.
(I) Anti-static precautions Anti-static labels
1. The operator must wear a grounded anti-static wrist strap and wear anti-static shoes and anti-static clothing.
2. If the LED is damaged by static electricity, it will show some bad characteristics: the leakage current increases, the static forward voltage decreases or rises, and it does not shine or emits light under low current test.
3, all equipment and instruments that contact the LED must be well grounded, especially soldering iron and tin furnace must be well grounded.
4, anti-static wrist must be tested every day, failed must be replaced.
(b) Pin formation method
1. The stent forming must be done with a jig or a professional.
2. The forming of the bracket needs to ensure that the pins and spacing are consistent with the circuit board.
3, must be 2 mm away from the colloid to bend the stent, so as not to cause colloidal rupture or damage the internal structure.
4. Bracket forming must be completed before welding.
(c) Use current
1. Excessive current will cause the LED lamp to burn or decay.
2. Since the LED has a characteristic that the current increases rapidly as the voltage is slightly increased.
3, in use should be added a resistor and LED lights in series, play a role in limiting.
4. The LED should work under the same current conditions. It is generally recommended that the LED current be 15-19mA.
(D) LED welding conditions
1, soldering iron welding: soldering iron (up to 30W) tip temperature does not exceed 300 °C; welding time does not exceed 3 seconds; welding time does not exceed 3 seconds; welding position at least 3 mm away from the colloid.
2, dip solder: dip solder maximum temperature of 260 °C; dip soldering time of not more than 5 seconds; dip soldering position at least 2 mm from the colloidal.
(five) brightness test and product instructions
1. When using the products with spectrophotometric separation, please sort and use according to the sequence of the BIN number. It is not allowed to mix different BIN number LEDs in the same product to avoid the difference of color, brightness and voltage. If you want to mix BIN numbers, adjacent BIN numbers can be put together but try to avoid them.
2. When detecting and using LEDs, it is necessary to provide the same current or constant current detection to each LED so as to ensure that the detection brightness is consistent. The current should not exceed 20mA, and it is best to use a current of 15-19mA.
(f) LED installation method
1. Be sure not to install the LED with the pins deformed.
2, when installing the LED, Jian intend to use guide sleeve positioning.
3, pay attention to the arrangement of various types of devices outside the line to prevent the wrong polarity. The device must not be placed too close to the heating element.
4. When you decide to install in a hole, calculate the dimensions and tolerances of the holes on the face and the circuit board to avoid overstressing the bracket.
5. Before the soldering temperature returns to normal, the LED must be protected from any vibration or external force.
(7) Cleaning
Care must be taken when cleaning colloids with chemicals because some chemicals cause damage to the colloidal surface and cause fading such as trichloroethylene, acetone, and the like. Ethanol can be used for wiping and dipping. The time should not exceed 3 minutes at room temperature.
