Standard requirement for LED lighting package drop

A drop test generally refers to a free fall drop at a certain height after the product is packaged (in the outer box), and finally see if there is any damage. The drop test is mainly used to test the damage of the product after it is packaged. It is used to evaluate the impact strength of the component when it is dropped during the handling process, and the water chestnut, corner and surface of the packaging container need to be tested.

Purpose
To determine the product’s adaptability to resist throwing, compression, and falling during the process of handling, transportation, storage and use, including cartoon boxes, whether the product packaging method is perfect and meets the requirements to achieve the purpose of packaging and protecting the product or to determine the lowest level of firmness required for safety. LISUN design Automatic Double Drop Test Machine is according to GB4757.5-84), GB/T4857.5-92,  GB/T2423.5, IEC60068-2-27, JISZ0202-87, ISO2248-19, ISO2248-1985(E, ASTMD5276-1998 and ISTA3A.

The principle of the drop test-the package is dropped on a hard, flat horizontal surface according to the specified height, and the test to evaluate the ability of the package to withstand vertical impact and the protection of the package to the contents. Drop test, also known as droptest/HG-318. It is used to simulate the drop that the product may experience during handling. These include:
• The product in the unpackaged state may endure free fall during transportation. The sample usually falls from a specified height to a specified surface in a specified posture.
• Simulate the repeated free fall that connectors on load cables, small remote control devices, etc. may experience during use.
• The package has dropped.

The main parameters:
•  Drop height
•  Number of drops
•  Falling to the surface

Restricted factors:
•  Height
•  Sample shape (for free fall)

The drop test procedure can usually refer to the following steps:
•  Preparation of the sample board before the test.
•  The function, safety and appearance of the product must be tested before the test, and the drop test can be carried out after confirming that it is normal.

•  The samples must be packed according to the prescribed method (refer to the production instructions or specifications), and the accessories must not be left out.
•  If there are special requirements for sealing (such as tape), proceed as required. If there is no special requirement: use 2 inch transparent adhesive paper for the package box, and 3 inch transparent adhesive paper for the outer cartoon box.

•  The test sample shall not be less than 2 FCL or 4PCS finished product.
•  Drop sequence.
•  The bottom corner of the seam side.

Operating procedures:
1. Wiring: Connect the supplied power cord to the three-phase power supply and ground it, connect the control box and the testing machine with the supplied cable according to the plug fit, and try to run the up/down command. (If During operation, if you press the up button but run down or press the down button but run up, you only need to change the number of phases at the power supply.
2. Fall height adjustment: turn on the power of the host, set the height required for the test (the method is as follows), press the up button to reach the set height; if it stops halfway, it must reach the set height before the reverse can be performed Run the command;
3. Place the object to be measured on the work surface, and then fix it with a fixing rod;
4. Press the up key to raise the measured object to the set height;
5. Press the drop button to instantly separate the worktable from the measured object, and the measured object can fall freely;
6. Press the reset button to restore the workbench to working status;
7. If the test is repeated, repeat the above steps.
8. After the test: press the down button to make the work surface run to the lowest position and turn off the power button;

Drop height requirements:
There are special standards for drop test countries. The drop methods are free fall of one corner, three sides, and six sides. The height of the drop is determined by the weight of the product.

1. If the weight of the lamp packaging is between 0-68kg, it will fall in a one-point, three-sided and six-sided manner. The relationship between the height of the drop and the weight is shown in the following table:

Number	Weight of package		Free drop height
	More than or equal to	Less than
1	0	9.5KGS	76.2cm
2	9.5KGS	18.6KGS	61cm
3	18.6KGS	27.7KGS	45.7cm
4	27.7KGS	45.3KGS	30.5cm
5	45.3KGS	68KGS	20.3cm

2. If the weight of the lamp packaging exceeds 68kg, it will fall in a six-sided manner, and the height of the drop will be 15.2cm;

Judgement result:
After the drop test is completed, the appearance, functionality and stability, and electrical safety performance should be re-examined according to the inspection procedures for finished lamps. It is required that the appearance should not have defects such as damage, depression, deformation, etc., and there is no change in performance, it is judged as qualified; otherwise, it is unqualified;

Packaging requirements:
After the drop is completed, the entire package must not be severely deformed (drop to the package).

Appearance requirements:
No gaps, cracks, damage, deformation, etc. should appear in the test samples of the lamps (refer to the appearance inspection standards of each lamp for details).

Internal structure:
After the drop is completed, the cover must be opened for inspection to observe that the fan, motor, connectors, fasteners and other components are installed well without loosening, cracks, damage, deformation, breakage, etc. (refer to the operating instructions of each lamp for details).

Functional requirements:
Self-propelled and use the console to run the lamp, test its light output, closed light, stroboscopic, single color, color mixing, focusing, horizontal, vertical and other functions are normal, the lamp beads can be fully bright, and there is no abnormal noise in operation (specific reference documents YJ/D-QC-029, YJ/D-QC–037, YJ/D-QC-036). Optical performance—parameters such as illuminance, color temperature, power, and current meet the requirements.
