Cose che dovresti sapere sulle classificazioni IP

Cos’è la classificazione IP?

Il codice IP, o codice di protezione dall’ingresso, standard IEC 60529, talvolta interpretato come marketing di protezione internazionale, classifica e valuta il grado di protezione fornito da involucri meccanici e armadi elettrici contro intrusioni, polvere, contatti accidentali e acqua. È pubblicato dalla International Electrotechnical Commission (IEC). Lo standard europeo equivalente è EN 60529.

 

Lo standard mira a fornire agli utenti informazioni più dettagliate rispetto a termini di marketing vaghi come impermeabile.… Read More

The Fatal Defect of LED Lamps-Surge Voltage and Prevention_Part II

What is surge

Surge protection

Gas discharge tube

It is composed of a pair of cold negative plates separated from each other and encapsulated in a glass tube or ceramic tube filled with a certain inert gas (Ar). In order to improve the triggering probability of the discharge tube, there is an auxiliary triggering agent in the discharge tube. This gas-filled discharge tube has two-pole type and three-pole type.… Read More

Wie viele Lumen in einer Fußkerze

Ohne die Sonne hätte die Erde keine Energiequelle, um biochemische Prozesse am Laufen zu halten, und es würde kein Leben geben. Ein Merkmal der enormen Energie der Sonne ist die Menge und Qualität des von ihr ausgestrahlten Lichts.

 

Sichtbares Licht macht nur einen kleinen Teil der elektromagnetischen Strahlung aus, zu der auch Radiowellen, Mikrowellen, Röntgenstrahlen und andere “unsichtbare” Wellen gehören.… Read More

LED de remplacement pour tubes fluorescents

Qu’est-ce que la lumière fluorescente?

Une lampe fluorescente, ou tube fluorescent, est une lampe à décharge à vapeur de mercure à basse pression qui utilise la fluorescence pour produire de la lumière visible. Un courant électrique dans le gaz excite la vapeur de mercure, qui produit une lumière ultraviolette à ondes courtes qui fait alors briller un revêtement de phosphore à l’intérieur de la lampe.… Read More

Hvor høj er et gadelys?

Gadelys, også kendt som lygter, lygter og gadelamper, er hævede offentlige armaturer, der giver belysning på kanten af en vej eller sti, når der er behov for lys. Lysfølsomme fotoceller aktiveres automatisk ved skumring, daggry eller i starten af mørkt vejr. Gadelys blev først brugt i byen Antiochia fra det 4. århundrede for at beskytte fodgængere fra at snuble på en sti.… Read More

Kuinka LED-valoihin vaikuttaa korkea lämpötila

Monet teollisuudenalat tarvitsevat korkean lämpötilan laitoksia tuottaakseen tai prosessoidakseen, mikä aiheuttaa erilaisia vaaroja välttämättömyydestä. Vaikka näille teollisille prosesseille vaaditaan aina tietty määrä riskejä, tämä ei tarkoita sitä, ettemme voi työskennellä keinoilla vähentää riski mahdollisimman pieneksi. Vaikka se ei välttämättä ole heti ilmeistä, LEDien käyttö voi auttaa kuljettajaa minimoimaan riskin.factory lighting

How to Choose Commercial Office Lighting

Business lighting is also called commercial lighting. The obvious difference between it and home lighting is that the application site is different, so there are obvious differences in requirements, design, and product features. Commercial lighting has scientific definitions and requirements for the illuminance, color temperature, and color rendering of light sources used in specific commercial environments. Different commercial office lighting requirements are different.… Read More
