What is LED

LED is the abbreviation of English light emitting diode (light emitting diode), its basic structure is a piece of electroluminescent semiconductor material, placed on a leaded shelf, and then sealed with epoxy resin around, plus a suitable voltage, it glows normally.

Some Common Sense of LED Beads

Common sense of LED chip size

According to the appearance classification, the chip is generally divided into round and square.… Read More

The difference between warm white, cool white and pure white

The so-called LED lamps, as the name suggests, refer to lamps that use LED (light emitting diode, light emitting diode) technology as the main light source.

LED is a solid-state semiconductor component, which uses current to circulate forward to the semiconductor pn junction exchange, and then the negatively charged electrons and positively charged holes separated from the semiconductor combine with each other to generate photons Emission, different types of LEDs can emit light of different wavelengths ranging from infrared to blue, and violet to ultraviolet.… Read More

Smart lighting market analysis

Street lights can not only achieve simple lighting, but also control the time and brightness of the lights according to the weather and the flow of people; lamp posts no longer just support street lights, but also help you make choices to avoid stagnant water and avoid congestion, and even become you The entrance to connect to WiFi.… Read More

LED Dimmer

The dimmer is an electrical device that changes the luminous flux of the light source in the lighting device and adjusts the illuminance level. The purpose of the dimmer is to adjust the different brightness of the light. By reducing or increasing the RMS voltage, the light output of different intensities produced by the average power lamp is promoted.… Read More

What is the light effect of LED lamps

LED lighting efficiency (luminous efficiency), the luminous flux emitted by the light source divided by the power consumed by the light source. It is an important indicator to measure the energy saving of light sources.

Luminous efficiency is a parameter of a light source, it is the ratio of luminous flux to power.… Read More

The Advantage of LED Lights

1. High efficiency and energy saving
   It only consumes a few kilowatts of electricity in one thousand hours (ordinary 60W incandescent lamp consumes 1 kilowatt of electricity in 17 hours, and ordinary 10W energy saving lamp consumes 1 kilowatt of electricity in 100 hours).

2. Long life
   The semiconductor chip emits light, has no filament, no glass bulb, is not afraid of vibration, and is not easily broken.

LED grow light is an artificial light source that uses LED (light emitting diode) as the luminous body to meet the lighting conditions required for plant photosynthesis. Classified by type, it belongs to the third generation of plant supplement light lamps.

In an environment lacking daylight, this lamp can act as daylight, enabling plants to grow and develop normally or better.… Read More

Railway station lighting analysis

As a long-term service infrastructure, the railway station is the city’s century-old foundation. With the vigorous development of commercial and indoor lighting in the past 50 years, railway station lighting has not only met the simple needs of general lighting for passengers buying tickets, waiting for trains, and entering and exiting stations, but also added more human factors and combined with the functions of railway stations.… Read More

Brief Introduction on LED Beads

LED Beads

LED English is (light emitting diode), LED lamp bead is the abbreviation LED for light emitting diode, which is a popular name.

Principle of luminescence

The terminal voltage of the PN junction constitutes a certain potential barrier. When a forward bias voltage is applied, the potential barrier drops, and the majority carriers in the P and N regions diffuse to each other.… Read More
