The structure characteristics of amount

Amount to the form of the structure to roughly two kinds, one kind is shaking type amount, the other is a lens scanning amount.
(1) type amount shook his head, is originally envisioned when the amount of origin form, its advantage is that the lamp body rotation driven beam movement, rotation range is big, can be 360 ° rotation. This movement effect can produce lasting appeal is dye-in-the-wood feeling on the stage.
2 lens scanning amount, it is depend on the lamp holder of a reflector light devices for department swing to projecting beam. Lens pitch bearing is driven by two motors, the motion of the complete vertical and horizontal. Its biggest advantage is: the lens is very light, control rise very convenient and quick, can produce very fast beam movement. Its defect is: affected by the mirror axis, beam movement range is smaller. As a result, more suitable for hanging.
Denominated in the function of the amount of features
Our amount of complete function: generally includes light color changes, the three primary colors combination, combinations of light and shade change, design change, design effect of rotation changes, prism effect, soft light, lens aperture contraction changes changes, camera lens, lens, zoom, stroboscopic light beam changes, etc.
An amount of control characteristics
Amount is made up of executive components and control components, the change of the amount of each kind of output light, namely, the movement of the light beam, light color, project design, the brightness of the light intensity, etc., are carried out by the motor control special optical device. Amount control is performed by a computer, each amount is equipped with one or several cpus, through the CPU processing, given the amount of the console of lighting art instruction sent to every movement of motor. These groups of digital signal from the control instruction is by computer, every movement of the motor change corresponds to a digital coding, every change of output beam corresponds to a set of Numbers. Now our company is generally USES the control signal is the DMX512 signal.
Through amount of address code set
Amount of using digital signal control, using a more general international DMX512 control protocol. Each lamp only has one's own code, the console issued instructions through the code to identify each lamp. Amount of encoder is generally installed in the tail end of the lamp (lens scanning amount) or the base of the lamp (head amount). Now commonly used encoder has digital and switch type two kinds.
___________ digital encoder is set
Set up digital encoder is relatively simple, usually by the encoder menu, set by flip turn to address, and then using the "+" on the encoder (up/Sunday afternoon) "-" (the down / ∨) symbol key to change the size number, is determined, by pressing the "ENTER" to confirm. Each amount should be given a digital start address code, to ensure that the amount of can react to the correct control signals. Numbers start address number is a channel number, with this number, amount can begin to "follow" digital control commands from the controller.
(1) amount of Numbers starting address calculation method:
The number of the current amount of starting address value = (the value of an amount of digital starting address) + (number of basic channel controller). For example, one with 16 channel amount. The first light starting address code is 1, is set to "001"; The second lamp starting address code is only 17, is set to "017"; So on, the third lamp only starting address code is 033, is set to "033". The first lamp is 001, the second stage: 1 + 16 = 17, the third stage: 1 + 16 + 16 = 33, now our SA043, SA001C, SA036, SA035B etc. The amount of the encoding has been adopted.
Set this switch type encoder
Also some amount of switch type encoder is used, it is composed of two of nine small switch (are exceptions), when the switch is placed in the "on" position, show that the switch on behalf of the numerical code will work. For example, to set the initial amount of address code is 1, it will switch to "1" in the "on"; To set the starting address code is the amount of 41, will switch to "1", "4" and "6" in the "on"; So on, can set all of the amount of address code.
And matching of the amount and the amount of the console
Our amount is generally use DMX512 signal control connection, however, there are many different types of brands at home and abroad amount of the console, the control signal output is endless also and same, some still cannot output DMX512 control signals. Therefore, for the amount of choosing the console, must consider good matching problem, can have a look at the selected console output current worldwide more general DMX512 control signals. Also want to have a look at the console has several control, usually a DMX512 control mouth there is a limit to the amount of the amount of control, control the mouth, the more the more you will control the number of amount. A DMX512 control can control the amount of mouth number (N), can be calculated by type: N = 512 present Nc (including type of Nc is a amount of channel number),
㈥ amount of signal lines
Amount is digital equipment, they are through the signal line stringing together, to execute commands from the amount of the console provides, to complete various actions (the light of the change of movement, color, pattern transformation, etc.). If a pair of signal lines exist hidden danger, will cause the control of the whole system is disorder, unable to function properly. Normally, signal control had better not exceed 150 m in length, otherwise, the control signal attenuation is serious, can't very good control amount. If the line is too long, be about to consider increasing the signal amplifier. In our practical work, we have many trouble, is caused by the signal lines. Therefore, before the connection signal lines for each signal a serious measure, and appropriately increase signal amplifier in the control loop, often can achieve twice the result with half the effort.
The running mode of ㈦ amount:
(1) the DMX512 control mode;
(2) automatic mode;
(3) the walk mode;
(4) master-slave mode;
(5) acoustic mode.
㈧ control channel:
Our amount of some kinds of DMX control channel up to 32, such as SA050 1200 w moving head light, channel said the light function, the more the more the better.
㈨ safety knowledge
The installation of the same amount of installation
Before the lamps and lanterns of positioning, to ensure the stability of the installation site, guarantee good firmly according to pick up, and completes the safety measures.
(1) and the target object, the minimum distance:
In the positioning of lamps and lanterns, light illuminate objects and the distance between the lens of lamps and lanterns should keep at least 1 meter distance.
2 minimum distance with flammable objects:
When the installation location and lamps and lanterns, any point on the surface of lamps and lanterns and minimum distance of 1 m any flammable materials.
(3) the maximum temperature:
Don't install the amount in the high temperature environment, to ensure that the lamp working environment temperature is highest do not exceed 40 ℃, the lowest not more than 15 ℃.
(4) and electric shocks, and static electricity protection:
Lamps and lanterns to use and have good grounding power system connection. And the ground wire must be connected with the ground wire of the power supply system of lamps and lanterns, lamps and lanterns of metal shell of the earth sign port to be connected to install fixtures are safe.
5] connect the power cord:
Check the amount of power supply line voltage and frequency of the electrical data, such as whether to match the lamps and lanterns of voltage and frequency parameters, avoid the lamps and lanterns of high pressure electric burn. With reference to the bulb power of the amount of use to connect all the lamps and lanterns can be calculated by 1.5 times, the maximum power supply power of the power supply parameter values.
The installation of this bulb
(1) lamps and lanterns is not installed inside the light bulb, don't be to the amount of processing power, or you will burn out amount.
(2) in the bulb when installation, must cut off power supply.
(3) the light bulb work will reach the highest temperature and gas discharge bubble can not continue to the physical characteristics of a power supply, so we must in every time, when the power is 15 minutes to cool completely for any operation. Otherwise it will lead to high voltage discharge, short circuit, and even burn out components on the computer console.
3. Other matters needing attention
U don't disassembling or modified amount without authorization.
U don't let the amount of contact with water or other liquids and metal of any kind (IP20).
U don't will beam on the tinder. Between amount and combustible materials should keep a distance of at least more than 5 m.
U don't look straight into the beam of the amount, otherwise it may cause harm to the eyes.
U don't use amount of the rotation of the arm to lifting or carrying amount.
U before open the amount of products or the desire for repair work, be sure to confirm the power supply is in off state.
U light bulb work will reach the highest temperature and gas discharge can not intermittent power supply of the characteristics of bubble, must therefore be after each power more than 15 minutes to cool completely for any operation! Otherwise it will lead to discharge, short circuit, and even burn out amount of components on the control panel.
(10) maintenance and maintenance
Before maintenance disassembly, lamps and lanterns products to disconnect the power supply connection, not charged operation, after power off, any other part of the lamps and lanterns can't tear open outfit in 10 minutes. If need to change the light bulb, need to wait for 15 minutes, let cool completely before bulb.
Any bulb has the service life of the lamps and lanterns, the use of the amount of light bulbs don't exceed its rated service life, otherwise it may produce the bulb burst, the light bulb when the blast shock wave can damage the condenser system inside the lamps and lanterns, is also likely to produce high voltage breakdown electronic parts. High temperature bulb fragments may scald of people, objects, and it may even cause fire.
Lamps and lanterns of the lens or lenses and other rotating parts must be checked regularly and keep it stable, if there is a obvious damage or loose, must be timely to replace reinforcement, in case of an accident.
Product of lamps and lanterns USES wind cooling, easy to dust, keep the lamps and lanterns is clean, clean is very important, especially the cooling air intakes. Otherwise easy to jam, inlets, led to the failure of lamps and lanterns. Often keep clean not only preserve brightness lights have the largest output. But also can prolong the service life of it, it is recommended to use high quality professional glass cleaner and clean flannelette, under any circumstances do not allow the use of alcohol or chemical solvent, design can be cleaned with a soft brush, and the internal use of lamps and lanterns vacuum cleaner at least once a year, double color filter and color design should be cleaned once a month, should be cleaned once a month.
