The first Guangzhou International Light Festival opens

The first Guangzhou International Light Festival opened on the evening of the 26th in Guangzhou's Tabei Plaza on the side of the Pearl River.

Including along the Pearl River, both sides of the river as well as the sky are all light show area, the opening ceremony full use of stage lighting, laser, light painting, projection, performance dance, fireworks and other light and shadow linkage, with the scene of the Guangzhou Symphony Orchestra 120 people large symphony performances, will be enthusiastic Various urban emotions, such as romance, passion, and aestheticism, are presented to the general public with lights and music. They show the public the charm of the festival and also promote the new concept of energy saving to the public.

The Guangzhou International Light Festival will be held from the 26th to the October 15th for a period of 20 days. During the Festival of Lights, in addition to viewing the art lighting exhibition integrating science and technology and culture, the public can also visit the energy-saving lighting exhibition organized by the organizer to visit the latest lighting products, lighting technology, city lighting and energy-saving achievements.

Most of the light sources used in this festival are energy-saving LEDs (light-emitting diodes). Guangdong is a national lighting industry base, and Guangzhou produces low-carbon and energy-saving LED products accounting for 20% of the country's total. The Guangzhou municipal government hopes to create the “Guangzhou International Lighting Festival”. To become an iconic theme activity in cities with sustainable development and international standards, and to promote the development of Guangzhou's cultural tourism and low-carbon and energy-saving lighting industries such as LED, and promote the promotion and application of energy-saving lamps in China.

0-10V Dimmable:

Used as an early fluorescent dimming system and still used today, 0-10V dimming has been adapted to become a reliable LED dimming control protocol.0-10 V is one of the earliest and simplest electronic lighting control signaling systems; simply put, the control signal is a DC voltage that varies between zero and ten volts. The controlled lighting should scale its output so that at 10 V, the controlled light should be at 100% of its potential output, and at 0 V it should at the lowest possible dimming level.

Dali dimmable: 

A basic system could consist of a few light fittings and a switch connected to a DALI group controller. The switch provides on/off control and up/down dimming of the fittings. Minimal configuration is required and ballasts do not need to be individually addressed.A grouped system consists of multiple ballasts individually addressed on a DALI Line Inputs on a Line Controller or a group controller can be configured to provide switching and dimming as required.

SCR Dimmable:

A SCR is a four-layer solid state device that controls current. In the normal [off" state, SCR restricts current to the leakage current. When the gate-to-cathode voltage exceeds a certain threshold, SCR turns [on" and conducts current. A SCR will remain in the [on" state even after gate current is removed so long as current through the device remains above the holding current. Once current falls below the holding current for an appropriate period of time, the device will switch [off". If the gate is pulsed and the current through SCR is below the holding current, SCR will remain in the [off" state.To achieve the dimming effect using SCR dimming technique, first, a RC phase shift is used to delay triggering the gate-to-cathode voltage. There will be a phase-cutting and the Root Mean Squared Voltage VRMS is modified. The symmetric characteristic of DIAC (DIode for Alternating Current) can be used to trigger TRIAC (TRIode for Alternating Current) symmetrically. Then, the dimming effect can be achieved by varying the R1 value that changes the phase angle for conduction.

Zigbee:

Zigbee is a kind of brand-new, focus on low power consumption, low cost, low complexity and low rate of short-range wireless communication technology.Is also a big focus in the embedded application.
