What is the meaning of led light what use

1, LED is a - a semiconductor diode that can convert electrical energy into light energy. LED and general diodes, like PN junctions, is also a one-way conductive. After the forward current is applied to the light-emitting di_ tube, will be injected from the P region into the N region of holes and N region into the P region of electrons, in the PN node around a few microns, respectively, with the N region of electrons and P region of holes were compounded, thus forming a spontaneous fluorescence. In different semiconductor materials, electrons and holes are in different energy states.

High power LED lamp heat dissipation performance factors

LED lights have features such as energy saving and environmental protection, but the actual operation process is easy to generate a lot of heat, once the heat can not be discharged, it is easy to have a high temperature resulting in abnormal chip heat, light source decline and reduced lamp life, etc. In simple terms, the LED lamp thermal management structure is mainly chip-level sealing, packaging level and system integration thermal level.

LED lamps and lanterns at night slightly bright six main reasons and solutions

The six main reasons and ultimate solutions for LED lamps and lanterns to be slightly bright at night after turning off the lights. At this stage, LED has fully replaced halogen and fluorescent light sources because of its energy saving and power saving, high brightness, long life and other advantages.

What are the common wiring methods of outdoor LED lighting

Outdoor LED lighting wiring first consider the use of the environment, outdoor to consider many factors, waterproof and dustproof, high temperature resistance, aging resistance, etc.. Cable wiring is not well protected, in the use of the situation may occur a lot of safety accidents, so under normal circumstances will do a good job of protective measures.

Common dimming methods of LED lights

LED era is developing rapidly, the control of lamps and lanterns is no longer simply open and close, a variety of dimming methods have been used in a variety of shopping malls, hotels, office buildings to meet the needs of different times, different scenes on the light environment.

LED lamp beads dead light causes

In the production process will always encounter a part of the lamp beads in the paste board after the test found a, a string, a few strings of lamp beads can not light up the phenomenon, for this phenomenon to make a summary:.

Three major trends in the future development of China's lighting industry

Lighting industry after more than thirty years of development, to this day, the public well-known brands are still ****. This is certainly related to the industry's low attention to industry attributes, but the more important reason is that the vast majority of lighting companies brand awareness is weak, they put their efforts on the product and price level of competition, rather than the brand and cultural level of competition. Of course, there are some enterprises, want to do the industry well-known brand, but not rules and regulations, half the effort.

LED lighting installation must be tested for points

1. luminous intensity detection Light intensity is the intensity of light, is the amount of light emitted within a certain angle. Due to the concentration of light-emitting diode light, the inverse square law is not applicable to short-range situations. cie127 standard for measuring the average normal light intensity provides two conditions: measurement condition A (far-field conditions) and measurement condition B (near-field conditions). The detector area in both cases is 1 cm2. usually, the standard condition b is used to measure the luminous intensity

8 common LED lamps and lanterns optical parameters testing techniques

The intensity of light, that is, the intensity of light, is the amount of light emitted at a certain angle. cie127 standard, the light-emitting diode due to the light is more concentrated, the inverse square law does not apply, cie127 on the measurement of light intensity proposed measurement conditions A (far-field conditions), measurement conditions B (near-field conditions) two conditions for measuring the average normal light intensity, 2 conditions are 1cm2. generally speaking, the The luminous intensity is measured using the standard condition B.
