Lamps AND lanterns are indispensable necessities in every household life, so the inspection of lamps and lanterns and detection appear particularly important. Then how to inspect the lamps and lanterns? This article will give you a detailed introduction to the lamp inspection method and step guide.
I. Inspection requirements for all kinds of lamps and lanterns
(I) Requirements and basic requirements for inner and outer boxes:
1, five layers of double B corrugated, face A inside B standard outlet box.
2. Color box (1) laminating (2) glazing (3) ordinary, color and content shall be inspected according to the contract. Box type, white board, single E corrugated, double E corrugated, inspected according to the contract.
Lamps are divided into outdoor lights, floodlights, courtyard lights, indoor lights, buried lights, underwater lights, sky lights and so on. Lamp materials are aluminum die casting, copper die casting, copper Hongchong. aluminum profile, stainless steel pull up iron sheet pull up. Zinc die casting, PC, ABC plastic products, etc. So according to different lamps and applications. Reasonable inspection according to the requirements, the premise of inspection is to confirm with the factory when our company contracts with the factory. Various production requirements and product quality to produce qualified products. Our purchasing department and sales staff should be familiar with the products and their requirements. To purchase cost-effective products. Ensure the integrity of the overall product, performance safety, good consistency.
(2) Aluminum die-casting lamp:
The market is now inconsistent with the price. So the same product with, requirements are different. But the basic requirements must be met. These are usability, security, and appearance.
The following are the basic inspection requirements for aluminum die-casting lamps:
1. The size, weight, smooth surface, no scratch and color are in accordance with the contract. The surface treatment has no peeling phenomenon. Scratch tests are strictly required.
2, the various parts of the lamp, up and down, anastomoses, should be good. The appearance should be free of flares, rough edges, large depressions and molds. Can meet the contract requirements IP level.
3. The screws used are all national standards. In general, the exposed stainless steel. For example, the lock aluminum cover of the high chandelier is a large piece of screw, and there are many kinds of screws, which should be reasonably matched according to various lamps and lanterns. Large tooth pads are necessary for stationary ballasts. Need to Pierce the paint layer. Make the grounding path good.
4, the outdoor light with punching parts, namely, electrical board, bracket, according to the requirements of various lamps, such as ordinary 400W lamp, bracket thickness 3mm, 40mm width, electrical board for 1mm, white zinc plating or galvanized plate.
5. Electric lamps and lanterns are generally wired with silica gel. The wire diameter is consistent, L is brown and red, N is blue and yellow and green (and grounding symbol), the wiring end must be tightened, the line is correct. Grounding screw ribbon pad (strictly required for power test and high voltage test) has obvious indication at the inlet line.
6, with electric light, internal and external temperature and IP test. Temperature is internal and external conventional value, and toughened glass can be tested. IP test.
7, reflector, there are ordinary. Imported plate, oxidized plate and thickness. The goods should be viewed in accordance with the contract.
8, sealing ring, temperature resistant rubber, temperature resistant silica gel, foaming silica gel, wire plug, etc. Inspect goods according to contract requirement.
3. Plastic lamps and lanterns
Plastic materials are relatively wide, but used in lamps and lanterns, ABC, PC, acrylic more. In the application, the new material is the first class, most of which are the first class return material. In the inspection, the goods shall be inspected strictly according to the contract.
1, lampshade: smooth surface, no scratches, flowers, small feed hole is better. Good product feed hole is not obvious, the higher the transparency, the better, tan times, hair orchid is less, generally oblique to show a little blue. Such as new material, color pure, transparent, if there is a pattern, should be clear stripes, no breakage and too large phenomenon. The dimensions are exactly the same as the bottom shell, horizontal and straight. The weight and so on meet the requirements. Such as PC, with the foot will not damage.
2. The lamp bottom, weight and size are in accordance with the contract. Can match the hood. The exterior color conforms to the contract. Bright, no scratch, other components reasonable, can not have too large plastic printing. There are no holes. No cracking and powder return at the screw installation.
3, electrical plate according to the contract requirements, thickness, hole position, plastic spray, etc. All requirements are reasonable, no ash, fingerprints. There is an obvious feed tape at the feed line. The inner and outer packaging is the same as other lamps and lanterns, and the electrical appliances are installed according to the contract requirements. The diameter and color of the electric wires are in accordance with the requirements of the lamps and lanterns. The emergency power supply must have reasonable wiring and can be used repeatedly. The battery should be securely installed, and the power supply should be disconnected when shipping.
