Koje su negativne pojave LED panel rasvjete na trenutnom tržištu?
The LED panel light reflects the highest level of lighting application of "seeing the light but not the light". It has the advantages of uniform light distribution, soft and comfortable, clean and bright, and has the advantages of anti-mosquito, anti-smoke, anti-fog and easy to clean; its shape is simple and easy to integrate with the ceiling module, so it is suitable for integrated ceilings, especially in complex environments and space. It has great application advantages in small bathroom and kitchen plates. At the same time, LED panel lights also have many characteristics such as low power consumption, energy saving and environmental protection, long life, economical use, fashionable technology, convenient application, etc., which are deeply loved by modern consumers.
Evo, hajde da seciramo lošu pojavu LED panel rasvjete na trenutnom tržištu sa tehničke tačke gledišta.
1. First of all, let's analyze the characteristics of LED light source devices currently used in LED panel lights because of their small size, suitable power, high light efficiency, easy light control and heat dissipation.
Second, let's analyze the driving power supply that is also the core component. Since the LED lamp bead is a low-voltage startup semiconductor device, the most basic requirement is to use a matching low-voltage power supply to drive, and to require a continuous and constant current (excessive current exists The light decays quickly, and the lamp becomes extremely dim or even burns out after a long time).
Trenutno postoje tri glavna tehnička rješenja za napajanje LED pogona:
1. Otporni-kondenzator sniženje-: shema je jednostavna, uređaja je malo, cijena je niska, a struja nije konstantna. Uglavnom se koristi u konfiguraciji LED lampi od 3W i ispod, a postoji opasnost od lomljenja ploče lampe i izazivanja curenja. Stoga, strukturni omotač tijela lampe mora biti izoliran.
2. Ne-izolovano napajanje: umjerena cijena, konstantna struja IC-a, ali postoji i opasnost od kvara ploče lampe i izazivanja curenja, tako da strukturna školjka tijela lampe mora biti izolirana.
Istovremeno, za isto izolovano napajanje konstantnom strujom, postoje i prednosti i nedostaci kao što su da li je shema razumna, da li je konfiguracija sveobuhvatna, da li je uređaj stabilan, da li je krug naučan i da li je proces je rigorozna.
Što se tiče procesa, visoko-kvalitetni pokretač standardnog proizvođača usvaja automatsko patch i automatsko lemljenje na valove, bez zabune i lažnog lemljenja, što se ne može zadovoljiti radioničkim procesom inferiornih proizvoda.
