Quality Management
At ShineLong, quality is one of the key things we put into consideration. We manufacture high quality LED lights that will satisfy all our customers. We use high-quality material and we have a team of experts who inspect the quality of the product from the first stage of manufacturing. Here are some of the things we put into consideration in making sure we meet our desired quality.
LED Lights (LED Tri-proof Lights) Safety Checks
ShineLong is unique because of its durability, compatibility, and high quality LED lights. Being a top-notch company, we check the safety of the LED Tri-proof lights and make sure it is good to be used by our customers. Our experts carry out some tests at this stage to ensure everything is all right. Some of the tests carried out include:
1. LED Lights Withstand voltage test
We make sure that we applied the correct voltage to our quality LED lights to avoid unnecessary breakdown. Our professional team does this by making sure that the product input including L and N wire and the grounding end of the withstand voltage tester connection / withstand voltage tester test rod and product shell reliable contact: Class I / II withstand voltage tester set test voltage AC1500V, test time 5s leakage current 10mA; test the product cannot have breakdown leakage arcing phenomenon (equipment can not appear alarmed).
2. LED Lights Grounding test
The test is only applicable to the products with grounding. Our experts test the two test clamps, a clamp on the ground, one end clamped on the exposed metal parts of the product shell: instrument parameters set 25A, limited resistance value should be 0.5 ohms, test time set 60 seconds, the test process equipment may not appear alarmed.
LED Lights (LED Tri-proof Lights) Function Checks
ShineLong manufactures products with high standards. We do not rush into commercializing our products before carrying out deep checks in making sure that their functionality is perfect and ready to be given to our customers. Some of the test we carried out to ensure the functionality of the lights are fine include:
1. Parameter test
Our experts access the product and check the voltage rate. The product power and power factor are in line with the order requirements (no special requirements when the product power: nominal power ± 10%; power factor pF≧0.9).
2. Light parameter test
The test is to ensure the nominal rated voltage of the panel light power supply, light parameter test is input. Considering its luminous flux (luminous efficiency), color temperature (CCT), color rendering index (Ra), etc. in line with the order requirements.
3. Emergency function
Some of the products with the emergency system of four input lines such as European standards and U.S standards. When the switch line is closed, the product must be completely closed without a light (the charging green indicator must be on). The non-switch line outside the L / N line any one power failure, the green indication should go out, and the product emergency light must be on (first to ensure that the battery has power, the product will not light / cannot start lighting when the battery is not charged).
4. Induction function products (infrared or microwave)
We check the induction function of our products based on their specifications in the ordered time. (± 10 seconds), the product off or slightly bright, in front of the product 120 degrees angle range, 5 meters away from the product walking products need to light up.
5. No stroboscopic products
The product rated voltage lit at maximum power test, the stroboscopic value of the stroboscopic meter needs to ≦ 1%.
6. Dimming function test
We ensure the consideration of the dimming function by checking the SCR/0-10V or DALI dimming, 3-5 products need to be connected in series together for the dimming test, and dimming process color/brightness changes need to be uniform and consistent (no obvious color or brightness differences, no light jitter).
LED Tri-proof Lights Structure Checks
ShineLong expertise team inspects the full structure of LED light starting from the size, material, and design of the product. The main things we focus on include;
- The size of the specification and the structure of the plug used must meet the requirements of the order.
- Product input line standard (European / U.S. standard) and the appearance of the way (single-sided / bilateral) and the corresponding "subject to the order" requirements, (no requirements for the length of the output line, the default exposed input line length of 600 ± 200mm)
- Checking that the mask structure is correct: we consider things such as foggy and striped of the product.
- Ensuring that the specification of the waterproof joint used for the product meets the order requirements
- Waterproof joints must be consistent with the requirements of the order, and waterproof joints must be tightened after threading (pull the product input power cord with five times the force of the product, and the expansion and contraction of the power cord shift must be less than 1mm).
LED Tri-proof Lights Appearance Checks
ShineLong being the leading manufacturer of quality LED lights we counter-check the physical appearance of the product so that it is easily separated from those of our competitors. We check the labels and logos in our products before sending them to the markets. These are some of the key things that we check on the appearance of our products.
- The parameter information on the product label is consistent with the actual input of the product (note the actual input voltage and current parameters of the product)
- Product lighting state, light must be uniform (the same product out of the light cannot exist color difference or brightness difference)
- Poor contact and flashing/flickering were found during the test
- The same batch of products should not have obvious color differences in the face cover
- Luminous surface foreign matter/impurities: Φ＞1.5mm, scratch area S＞15m㎡ (such as size 3*5mm, 1.5*10mm)
- Luminous surface foreign matter/debris 1.5mm ≥ Φ > 1.0mm spacing greater than 300mm, the maximum of 2 allowed on the entire product
- The non-glossy surface of rubbing discoloration Φ＞5mm
- The spacing of the rubbing discoloration Φ5mm≥Φ＞1mm on the non-light surface is greater than 300mm, and a maximum of 3 are allowed on the product
- Foggy mask products light up, no point light source phenomenon
- There must not be foreign objects or internal sounds in the product
- No leakage or loosening of the plug screw or rupture of the plug edge
- The back cover of the composite plug misses putting the waterproof rubber pad
- The plug is not installed in place, there is a skewed phenomenon
- The cover protrudes from the side of the aluminum tube > 1mm (the mask is not installed in place)
- The back of the product plugs needs to have a laser traceability code
- The letters, numbers, and symbols on the label are clear, and the label should be pasted in the correct direction (requiring the light side to be downward with the label character upward)
- Product label must have "Made in China" information: Made in China or Made in PRC. (Especially the United States)
- The surface of the product should be wiped clean, and there should be no moving foreign objects in the product.
Things we consider before commercialization.
The product label should be pasted at the terminal end (the bilateral line can be at either end, if the mask has laser information, it should be at the same end)
UL product stickers Sharon label or has made a sub-certificate customer label (UL anti-counterfeiting label cancellation)
TUV-GS products must be attached to the Sharon label with the customer’s name and address information label (European customers do not need to paste information labels for sub-certification); product line out generally use rubber wire.
