Eight tips to distinguish LED corn light
Configure virtual standard
LED corn light is also sell like hot cakes with price lower profits, in the fierce competition also LED to many businesses began to jerry qi product parameters, it is also the customer has repeatedly than price, require low price, is also related to the practice of a few manufacturer.
2. Counterfeit chips
LED corn light is the most core chip, directly determine the performance of lamps and lanterns!With customer's unprofessional some undesirable businessman, however, from the cost of the above consideration, using low price chip, make customer buy the low quality of the product with high price caused a direct economic loss, and cause serious quality hidden trouble to LED corn lights.
3. Copper wire as gold thread
Many LED manufacturers trying to develop such as copper alloy, gold silvering alloy wire, silver alloy wire to replace expensive gold thread.Although these alternative is better than that of gold thread on certain features, but poor in chemical stability but many, such as silver and gold silvering alloy wire is vulnerable to sulfur corrosion/chloride/bromide, easy oxidation of sulfide copper wire.For similar to suction breathable sponge encapsulation of silica gel, these alternatives to make wire bonding are more susceptible to chemical corrosion, the reliability of the light source is reduced, use time grew, LED lamp bead are more likely to break the dead light.
4. The lamp light distribution system design is not reasonable
Optical design, if the lamp light distribution system design is unreasonable, lighting effect is not ideal.Tests will appear "under the lamp light", "light black", "zebra crossing", and "uneven illumination", "yellow" and so on.
5. Bad heat dissipation design
Thermal design, LED chip junction temperature of PN junction every 10 degrees, the service life of semiconductor devices will be faster.Due to the LED corn light brightness demand is high, the use environment is harsh, if the cooling solution is not good, can rapidly lead to the LED aging, reduced stability.
6. Power failure
Drive power supply, power supply if there is failure, the process of testing and inspection, there will be a "whole lights" and "damage", "individual die LED lamp bead light", "the whole lights flashing virtual" phenomenon.
7. Security failure
Security issues is also worth serious attention: street light there is no power leakage protection;Street lamp ballasts quality shoddy;Circuit breaker for sensitivity test revision, rated tripping current selection is too large;Main cable metal sheath is used as the PE total process is complex, low reliability;IP waterproof and dustproof level is too low.

8. If there is harmful to the light source of lamps and lanterns
LED light source of black is each big LED company often encounter problems.Most of the material in the lamps and lanterns to be affecting the service life of the light source material.
