High-power LED Lighting Radiator Application

Current Status of Cooling Problems

High-power LED street lights, as the name suggests, are street lights with a power greater than 30 watts and a new type of LED semiconductor light source. The lifespan of LED street lights is 7 times that of ordinary ones. Due to the long lifespan, the LED street light does not need to be replaced in 12 years if it is lit for 11-12 hours per day.… Read More

Gli elementi di base della progettazione illuminotecnica

Gli elementi base della progettazione illuminotecnica comprendono principalmente:

1. Determinazione dell’illuminazione:

Lo standard di illuminamento degli edifici industriali è determinato secondo lo standard IEC “Lighting Design Standard for Industrial Enterprises” TJ34-79. L’illuminamento degli edifici civili deve essere scelto in base alle esigenze d’uso e secondo il “Regolamento tecnico per la progettazione elettrica degli edifici”.

 

2. Lampade ad alta efficienza luminosa:

Per l’illuminazione generale in luoghi in cui le lampade sono sospese in alto (come fabbriche alte), dovrebbero essere utilizzate lampade al sodio ad alta pressione, lampade fluorescenti ad alta pressione autoregolanti o lampade a LED ad alta efficienza (efficienza luminosa superiore a 120 lm/W).… Read More

LED De-power Design

1. LED Lighting Route Analysis

The design of the lighting fixture is based on the three-way combination of the LED light-emitting part, the drive control part and the optical heat dissipation structure design.

(1) Light-emitting part

With the continuous improvement of the luminous efficiency of LED light-emitting chips, the controversy over the inability of LEDs to save energy gradually fades away.… Read More

Was sind die LED-Beleuchtungsbedingungen?

Farbwiedergabeindex (CRI)

Bezieht sich auf das Erscheinungsbild eines Zielobjekts unter einer Lichtquelle im Vergleich zur Originalfarbe unter einer Referenzlichtquelle (z. B. Tageslicht), wie realistisch die Leistung der Originalfarbe entspricht

 

Kontrastempfindlichkeit (Kontrastempfindlichkeit)

Die Fähigkeit, Helligkeitsunterschiede zu erkennen, ist qualitativ ausgedrückt gleich dem Kehrwert der Kontrastgrenze

 

Abblendwinkel einer Leuchte

Gemessen vom tiefsten Punkt, dem Winkel zwischen dem ersten, vom menschlichen Auge nicht wahrnehmbaren, offenen Lichtstrahl und der senkrechten Linie

 

Diffuse Reflexion

Bezeichnet den Vorgang, bei dem der einfallende Lichtstrahl innerhalb eines bestimmten Winkelbereichs zurückreflektiert wird

 

Diffuse Beleuchtung

Bezeichnet ein Beleuchtungsverfahren, bei dem das einfallende Licht nicht hauptsächlich aus einer einzigen speziellen Richtung kommt

 

Diffusor

Bezieht sich auf ein Gerät, das das von einer Lichtquelle emittierte Licht reflektieren oder streuen kann, normalerweise hauptsächlich durch Diffusion

Direkte Blendung

Blendung durch extrem hohe Helligkeit, unzureichende Abschirmung der Lichtquelle oder starke Reflexion im Sichtfeld.… Read More

Introduction of LED Driving Principle

Since the light characteristics of LEDs are usually described as a function of current—the relationship between luminous flux (φV) and IF—rather than a function of voltage, driving with a constant current source can better control brightness.

Characteristics of Super Bright LEDs

The figure below shows the relationship between forward voltage drop (VF) and forward current (IF). It can be seen from the curve that when the forward voltage exceeds a certain threshold (about 2V), that is, the so-called turn-on voltage, it can be approximately considered that IF is proportional to VF.… Read More

Quels sont les termes d’éclairage LED

Durée de vie de la lumière

La durée de vie de la source lumineuse est également appelée durée de vie de la source lumineuse. La durée de vie d’une source lumineuse électrique est généralement exprimée en termes de durée de vie effective et de durée de vie moyenne.

  1. Durée de vie effective : fait référence au nombre d’heures d’éclairage ressenties lorsque la lampe commence à s’allumer jusqu’à ce que le flux lumineux de la lampe diminue à un certain pourcentage du flux lumineux nominal.

Feasibility Analysis of Partial Lighting Retrofit LED Lamps

Energy-saving Retrofit Access Plan

contract energy management

The contract energy management project is to fully mobilize the enthusiasm of energy-consuming units and energy-saving service institutions for energy-saving renovation of facilities, and to recover the project investment and obtain benefits by saving energy costs. Adopt investment subsidies and energy-saving incentives to support the implementation of energy-saving renovation projects through contract management. The following conditions must be met to adopt this scheme:

  1. The project is mainly invested by energy-saving service companies (at least 50% of the investment).

Retningslinjer for hospitalslysdesign

Drift og rent områdebelysning

Operationsstuen er det mest typiske rene rum på hospitalet. Det er et område, hvor læger udfører fint arbejde. Det kræver høj belysning og standarden kræver mere end 750lx. Det anbefales at udføre designet efter 1000lx, og samtidig forbedre farvegengivelsen så meget som muligt for at forbedre lægepersonalets fokus på sygdommen. Evnen til at genkende og bedømme farveændringerne i væv og blod.… Read More

Ultra-high Brightness White LED Application

1. Resistive Current-limiting LED Lights

The resistance current-limiting small spotlight or table lamp using 220V AC power supply is characterized by its simple production. According to the level of the power supply voltage in the region, generally 90-100 tubes can be connected in series. If the number of tubes is too small, the efficiency is relatively low.

Adjust the current limiting resistor R appropriately according to the power supply voltage and the number of tubes to control the current of the LED, generally not more than 20mA.… Read More
