Types of stage lighting How to distinguish the quality of LED stage lights
The so-called stage light is a kind of lamp that uses the light source to the stage lighting. There are many types of stage lights. In our daily life, we often encounter par lights, pattern effect lights, moving head lights, strobe lights, and display screens. Wait, of course, in practical applications, stage lighting is far more than these types, and general LED stage lighting is more popular. What are the types of stage lighting? How to distinguish the quality of LED stage lights? Let's follow Benwei to find out.
Stage lighting
Types of stage lighting:
1. Follow the light:
The so-called chasing light, this kind of light source is used to track the performers and highlight the specific light on the stage. This kind of light is the finishing touch of the stage.
2. Heaven and earth discharge:
This kind of light is mainly used for color change or lighting between sky screens, which is a type of light source that is poured into the sky screen from above and below the sky screen.
3. Bridge light:
The kind of light is mainly used to assist the column light. It is the light that is projected to the stage before the entrance of the proscenium.
4. Top light:
This kind of light source is a kind of ordinary stage lighting, which can enhance the stage illuminance and can be illuminated at a fixed point.
5. Flowing light:
This kind of light is used to assist the preparation of the bridge light, to supplement other specific lights on both sides of the stage and to supplement the light on both sides.
6. Foot light:
It is mainly used to assist surface lighting, and it has the effect of eliminating shadows.
7. Backlight:
It is a kind of light projected from the opposite direction of the stage, which can enhance the effect of transparency and three-dimensionality.
8. Pillar light:
It is a kind of light projected from both sides of the stage, which can enhance the outline of the highlight.
Stage lighting
The above is a brief introduction about the types of stage lighting. I believe that after the above introduction, everyone will have a further understanding and understanding of stage lighting. Of course, LED stage lighting is the most popular on the market because of its energy saving and good lighting effect. At present, the competition for LED stage lights in the market is becoming more and more fierce, and it is also full of all kinds of mixed brands. So how to distinguish the quality of LED stage lights? Let's take a look at the following introduction:
How to distinguish the quality of LED stage lights:
1. Strictly inspect the LED raw materials of the solid crystal station:
(1) Chip:
Mainly manifested as solder pad contamination, chip breakage, chip cuts of different sizes, chip cuts tilted, etc. Preventive measures: Strictly control incoming material inspection, and require suppliers to improve when problems are found.
(2) Bracket:
The main manifestations are that the deviation of the Θ dimension and the C dimension is too large, the bracket is discolored and rusted, and the bracket is deformed. Poor incoming materials are all problems of the supplier. The supplier should be notified to improve and strictly control the incoming material.
(3) Silver glue:
The main manifestations are the poor viscosity of silver glue, the expiration of the service life, the storage conditions and the thawing conditions do not meet the actual standards, etc. For the viscosity of silver glue, there will not be too many problems in production after engineering evaluation, but it is not that this kind of silver Glue is the best. If any defects are found, the project will be evaluated again. Other service life, storage conditions, thawing conditions, etc. are all controlled by humans. As long as the SOP is strictly followed, there will generally not be too many problems.
2. Reduce unfavorable human factors:
(1) Operations by operators in violation of regulations:
For example, if you don't wear gloves, the silver glue goes online without thawing after being taken out of the refrigerator, and the operators do not follow SOP operations, or are unskilled in the operation of the machine, etc., will affect the quality of the die. Preventive measures: foremen strengthen management, operators work according to SOPs, quality assurance personnel strengthen audits, strengthen education and training for unskilled personnel on machines, and are not allowed to officially start without a job certificate.
(2) The maintenance personnel adjust the machine improperly:
The countermeasure is to improve technical standards. For example, the height of the crystal, the height of the die, the height of the thimble, the setting of some delay time, the setting of the motor parameters, the setting of the table parameters, etc., all need to be adjusted to the best state according to the standard.
3. Ensure that there will be no machine defects:
The main performance of the machine is some parts or mechanical structure of the machine. If you recognize the influence of the system and other defects on the quality of the die, you must ensure that the various functions of the machine are normal.
4. Perform the correct tuning method:
(1) The light spot is not right:
Countermeasures-re-calibrate the light points to ensure three points and one line.
(2) Improper adjustment of various parameters:
For example: picklevel, bondlevel, ejectorlevel delay time, motor parameters, etc. It can be solved by adding a few steps and subtracting a few steps, but the results are completely different. The same is the height of the thimble. When the chip can't be sucked, someone tried hard to parameter, but did not consider whether the thimble was blunt or broken. As a result, the chip was damaged, Θ angle offset, etc. The delay time and the motor parameters are also the same. No, the action of the welding arm will be different, which will also cause abnormal quality.
(3) Improper setting of binary value:
Countermeasures-reset binarization.
(4) The standard of machine adjustment is inconsistent.
5. Master the manufacturing process:
(1) Whether the cleaning of the silver glue tank is regularly cleaned.
(2) Whether the choice of silver glue is reasonable.
(3) Whether the workers wear gloves and masks to work.
(4) Baking conditions, time and temperature of the solid crystal material.
