Hvad er ensartethed i belysning

Hvad er ensartethed i belysning?

Kort introduktion

Ensartetheden af ​​belysningsstyrke refererer til forholdet mellem minimumslysstyrken og den gennemsnitlige lysstyrke på den specificerede overflade. Jo mere ensartet lysfordeling, jo bedre lysstyrke og jo mere behagelig den visuelle oplevelse. Jo tættere lysstyrkeens ensartethed er på 1, jo bedre, ellers jo mindre visuel træthed.

 

Specifikke instruktioner

Belysnings ensartethed = minimum belysningsstyrke / gennemsnitlig belysningsværdi

Den mindste belysningsværdi beregnes efter beregningsmetoden punkt-for-punkt.… Read More

How to Choose LED Lights_Part I

The prosperity of LED has not only enriched the product market, giving consumers more choices, but also caused great troubles to consumers. Think about it: There are hundreds of brands, large and small, plus at least 10 models for each brand, which definitely makes laymen look dizzy and dazzled. How to “get rid of the dross and get the essence” from the dazzling, dazzling led jungle, this is a technical job.… Read More

Mikä on LED-valojen säteen kulma

Mikä on säteen kulma?

Valonlähteen tai lampun lähettämä valo ei peitä koko tilaa, koska niillä kaikilla on tietty valokulma, toisin sanoen alue, johon valonlähteen tai lampun valo voi päästä, on rajallinen. Jos saman muotokuvan valaisemiseen käytetään kolmea lamppua, joilla on sama teho, mutta erilaiset sädekulmat, näytetään erilaiset tehosteet.

Maallikon termien mukaan sädekulma viittaa kulmaan, jossa valonlähde tai lamppu lähettää säteen, toisin sanoen säteen muodostamaan kulmaan tietyn voimakkuusalueen rajaa pitkin.… Read More

Two Common Commercial Lighting Applications for LED Lights

1 Introduction

From the invention of the light-emitting diode in 1907 to the successful development of the blue LED in 1995, semiconductor lighting has undergone a tortuous process. This includes the “camp battle” between silicon carbide (SiC) and gallium nitride (GaN) in the development of blue LEDs. After the technical preparation for the early development of LED, it has now entered a period of rapid growth.… Read More

Hur man byter ut lysrör

Klassificering och fördelar och nackdelar med lysrör

Klassificering av lysrör

1: Enligt lampstorlek och effektklassificering:

Rörets längd är 12 steg från 135,9 ~ 2374,9 mm;

Effekten varierar från 4W till 125 W i 14 nivåer.

Effekten är uppdelad i två kategorier: högeffektiv och lågeffekt: högeffektiva lampor hänvisar till 65 ~ 125W, och lågeffektlampor avser mellan 4 ~ 40W.

Mått och effekt hos lysrör:

Effekteffekt Storlek Längd Diameter (mm)

8w -287 x 15mm

15W 436 x 38mm

20W 589 x 38mm

30W (tunt rör) 894 x 25mm

30W 894 x 38mm

40W 1300 x 38mm

  1. Klassificering efter rördiameter: Det finns fyra typer av rördiametrar: T5, T8, T10, T12

T5 T8 T10 T12

15 25 32 38 -diameter (mm)

3: Enligt klassificeringen av startmetoden finns det två typer av föruppvärmning och snabbstartstyper som är de mest använda.… Read More

Five Major Problems of LED Light Source

For general lighting, what people need is mainly a light source close to sunlight, so white LED has become an important indicator of lighting technology. However, there is still a long distance between white LEDs and general lighting requirements, and there are still many problems that need to be resolved.

1. Low luminous flux and high price.

For example: a single 1W LED device has a luminous flux of about 25lm.… Read More

Hva er DLC-sertifisering og standardene

Hva er amerikansk DLC-sertifisering?

For å forstå DLC-sertifisering, må du først forstå Energy Star. Energy-Star er et prosjekt ledet av den amerikanske regjeringen (US Environmental Protection Agency (EPA) og Department of Energy (DOE)), kombinert med deltakelse av produktproduksjon og detaljhandel, og er hovedsakelig rettet mot energiforbruk av forbrukerelektroniske produkter. Lagringsplan.

ENERGY STAR-sertifisering krever at alle produsenter sender inn testresultater utstedt av laboratorier som er anerkjent og godkjent av US Department of Energy og US Environmental Protection Agency, som er gjennomgått og godkjent av IAS for å være gyldige.… Read More

The Difference Between Tri-color Energy-saving Lamps and Ordinary Energy-saving Lamps

What is a tri-color tube?

The three-primary color tube means that the fluorescent powder in the tube as the luminous substance is a combination of three kinds of phosphors that can emit red, green and yellow light, which emits white light, and the light it emits is similar to the color of daylight; its manufacturing The cost is higher than that of ordinary fluorescent lamps, and it is more visually “comfortable” than ordinary fluorescent lamps.… Read More

Was ist der Unterschied zwischen LED-Licht COB und SMD?

Was ist COB?

COB-Lichtquelle ist eine hocheffiziente integrierte Oberflächenlichtquellentechnologie, die LED-Chips direkt an einem

Spiegelmetallsubstrat mit hohem Reflexionsvermögen. Diese Technologie macht das Konzept von Klammern, kein Galvanisieren, kein Reflow-Löten und keine Montageprozesse überflüssig, sodass der Prozess um fast drei Punkte reduziert wird. Die COB-Lichtquelle kann einfach als integrierte Hochleistungs-Flächenlichtquelle verstanden werden, und die Lichtemissionsfläche und Abmessungen der Lichtquelle können entsprechend der Produktform und -struktur gestaltet werden.… Read More

Selection of Desk Light Source for Reading and Learning

The lamps used in general households are mainly various types of lighting lamps, decorative lamps, etc., among which desk lamps are mostly used for reading and writing. In recent years, there have also been various lighting lamps in the name of protecting eyesight, such as health care lamps and eyesight protection lamps, on the market. So, what kind of light sources and lamps should be used for reading and learning?… Read More
