6.Common Testing Items for LED desk lamp Inspection
Tilt test
Tilt test in the most unfavorable place of the lamp body does not fall down.
Clamp light clamping force test
Clip on top of smooth glass of 10mmlf, 20N pulling force in the most unfavorable situation, no movement (based on safety regulations as the test)
Power cord pull test
25 times 20N pull on the power cord, after the first pull on the power cord to mark, the subsequent test finished power cord displacement of no more than 2mm (safety regulations as the basis for inspection)
Whole lamp temperature
Working state, the easy-to-reach parts of the lamp can not be overheated, not more than 70. C
The whole light effect
Shaking the whole lamp, the lamp body does not produce foreign body sound.
Power wire diameter
The wire diameter of internal wiring and external wiring is in accordance with safety regulations.
Lamp body shell trust test
Oil sprayed parts and painted parts must be tested for reliability (Hundred Gram Test)
Standard parts interchangeability
The parts used should comply with the corresponding standards, the same model of lamps and lanterns, the same parts should be good interchangeability, replaceable parts should have no difficulty and do not affect the safe replacement.
Overall lighting effect
No serious light leakage around the product luminous surface, and the overall no dark areas.
Labeling
There are company trademark, QCPAS Wei 100% logo, marking product model, rated power supply voltage, power supply frequency and power supply current, line power factor, rated power, or the model with which the lamp is matched.
After the test, the mark should be clearly written, and the label should not fall off and curl.
Lamp body
Product height and maximum diameter exceed the product specification requirements
Performance
No dead light, dark light, light flashing, color difference, light ringing and other phenomena when the rated voltage is lit, and the accompanying functions of the lamp work normally
Power
Rated voltage light source, power supply power meet the requirements
Power factor
Power factor under rated voltage does not meet the requirements
Color temperature
Test color temperature at rated voltage meets the requirements
Display index
Test color rendering index under rated voltage meets the requirements
Illuminance
The illuminance of the test at rated voltage meets the requirements
EMC
Test quasi-peak, average value, the measured frequency range (0.09MHZ-30MHZ, the measured quasi-front value and level value of the data must be below the baseline, shall not exceed the average baseline 5dB.
Harmonics
Electronic ballasts with low power factor less than 25W only consider the 3rd and 5th harmonics, of which the 3rd harmonic requires < 86, the 5th harmonic requires < 61 Electronic ballasts with greater than 25W harmonics require consideration of the 3rd, 5th, 7th, 9th, 11-39 odd harmonics, of which the 3rd harmonic requires < 30 into the 5th harmonic requires < 10, the 7th harmonic requires < 7, the 9th harmonic requires < 5, the 11-39 odd harmonics requires < 3

Humidity test
Humidity test in the humidity box first, the air temperature is 20-30 C, the temperature change during the test is Shi 1 C, humidity is 91%-95% test time of 48 hours, the test time to remove, and immediately the next step of insulation resistance test and voltage test. Intermediate test
Whether the light body is normally lit, if with touch switch, check whether it is not malfunctioning. (This item as a confirmation test, the regular test does not do this test)
Electrical strength
Withstand voltage test: Note that the test voltage to wear insulated gloves, respectively, two groups of tests, test time 60S, leakage current 5mA
a.Desk lamp
For SELV voltage of the basic insulation 500V
* When conducting the test, the installation surface is covered with metal foil
1）Between current-carrying parts of different polarity
2)Between current-carrying parts and mounting surfaces
3)Between current-carrying parts and metal parts of the luminaire
b.Power adapter
Double insulation or reinforced insulation|4U+2750V
*Mounting surface covered with metal foil when conducting tests
1)Between current-carrying parts of different polarity
2)Between current-carrying parts and mounting surface
3)Between the charged parts of different polarity that can be made by the action of the switch cannot be flashover phenomenon during the test, let alone the serious bad situation such as leakage by breakdown.
Insulation resistance
500VDG test 60S, insulation resistance requirements: between the positive and negative pole of the lamp, between the positive and negative pole and the installation surface and between the positive and negative pole and metal parts minimum insulation resistance of 1MQ power adapter between the positive and negative pole, between the positive and negative pole and the installation surface minimum insulation resistance of 4MQ
Fire resistance test
The sample (key electrical components) is burned with an open flame at a temperature of 650 degrees 50C for 30S.
Burn 30S, any flame or burning material of the sample should be extinguished after removing the burning wire for 30S. Falling incendiary or molten material should not cause the thin paper laid horizontally under the sample 200mm 5mm to catch fire. (This item is a confirmation test and is tested once every six months)
Outer box
