Ce sport se joue à l’intérieur et à l’extérieur sur un terrain de basket. Le basket-ball étant principalement joué à l’intérieur, l’éclairage a un rôle énorme à jouer pendant un match.… Read More
For a long time, the problem of light decay and life of compact energy-saving fluorescent tubes has been paid attention by most domestic manufacturers. With the revision of the national standard for self ballasted fluorescent lamps and the continuous reduction of the diameter of compact energy-saving fluorescent tubes (CFL), the phosphors bear more and more load, so it is particularly important to solve the problem of light decay.… Read More
Certification method of LED light source lumen maintenance rate measurement by lighting Engineering Association
The lighting engineering association approved the publication of the committee’s report. The revision proposal should comply with the relevant regulations of the lighting Engineering Association.
Lm-80 is suitable for packaging, array and module based on inorganic led. one Lm-80 is designed to guide the maintenance of optical output rather than any other failure mode.… Read More
Koripallopelaajat jaetaan amatööreihin, ammattilaisiin ja ammattilaisiin. Samoin koripallokentän varusteet luokitellaan. Esimerkiksi koripallokentän valaistus, alan standardi (International Lighting Association), on jaettu kuuteen luokkaan: Ⅰ (harjoittelu ja virkistystoiminta), II (amatöörikilpailu / ammattikoulutus), III (ammattikilpailu), IV (TV-lähetys kansallinen / kansainvälinen kilpailu), V (TV-lähetysten suuri kansainvälinen kilpailu), VI (HDTV-lähetysten suuri kansainvälinen kilpailu), tietysti todellisuus. Niiden ulkopuolella on monia koripallokenttiä, joilla on alhaisemmat vaatimukset kuin minulla (harjoittelu ja virkistystoiminta).… Read More
Many designers feel a headache about lighting design, not to mention you and me who don’t understand design. But home lighting also has a few easy to use and inexpensive rules. Although it can’t achieve the beautiful and advanced effects of hotels in one step, it is the easiest way for ordinary people like us.
The most important thing about lighting at home is that the lights should never be dazzling.… Read More
En solbelysning är en gata, parkeringsplats eller områdesbelysning som drivs helt av solenergi. Med ett batteri plus solpanel laddas det under dagen och tänds på natten. De finns i en mängd olika former och storlekar med valfria funktioner som rörelsesensorer och fjärrkontroller. De kan användas för kompletta projekt eller för att lägga till lampor på svåra platser för att ansluta.… Read More
The most common one on the market is a non-electrolytic capacitive light engine whose power efficiency is usually only about 85%. The LED lamp is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connects the chip and the circuit board with a silver wire or gold wire.… Read More
Ulempe 1:
Stor størrelse, kan bare brukes til grunnleggende belysning.
Lysrør må ha en viss lengde på rørdiameter på grunn av sitt lysemitterende prinsipp. Derfor er volumet på lampekroppen relativt stort, og lampens design er vanskeligere. Den kan bare brukes til grunnleggende belysning, og kan ikke brukes til nøkkelbelysning.
Fluorescerende lamper har god eller dårlig fargegjengivelsesindeks, og fargegjengivelsen er basert på typen fosfor.… Read More
When you see that the LED light on the board produces a color that changes over time, do you know how it is achieved?
Partners who have done MCU program or FPGA logic programming should know (there are many articles about PWM also specifically introduced), it is obtained by adjusting the brightness of the three colors of R, G, and B in the following way.… Read More
