Comparison of advantages between COB downlights and conventional lighting fixtures

In lighting, COB we call it the integrated LED chip COB downlight. As the name suggests, the downlight uses an integrated POWER LED chip. The COB downlight is a popular one among the current LED downlights .

COB downlight

COB downlight is a new concept of solid-state light source lamp. It has become one of the most promising lighting products in the world in recent years due to its unparalleled technical advantages of energy saving, environmental protection, long life and high controllability. It will also become The best alternative to traditional lighting.

COB downlights are superior to traditional lighting fixtures in terms of radiation form, color rendering, visual sensitivity characteristics, power specifications, brightness control, etc. With the advancement and development of industrial technology, it is gradually becoming a mainstream lighting fixture.

Compared to ordinary luminaires, COB downlights have unique advantages:

1. High-pressure sodium lamps, fluorescent lamps, and electrodeless lamps contain chemical pollutants such as mercury and lead. The COB downlight source does not contain chemical pollutants and is a green light source.

2. COB downlights have high reliability, low daily maintenance and repair costs, mean time between failures (MTBF) of up to 20,000 hours, and mean time between failures (MTBF) of high pressure sodium lamps and fluorescent tubes of less than 10,000 hours. .

3. COB downlights consume less power and save energy, saving more than 40% energy compared to traditional high-pressure sodium lamps.

4. COB downlight can realize instant start, easy brightness adjustment, with no stroboscopic, wide starting voltage range, etc. It can realize various energy saving methods, such as intelligent adjustment of illumination according to weather and environment.

5. COB downlights have a long life, ideally 100,000 hours, while high-pressure sodium lamps and fluorescent tubes have a lifespan of only 10,000 to 30,000 hours.

With its excellent performance, COB downlights have overcome various problems brought by traditional lamps, and have gradually become the future development trend of lighting fixtures. The strong support of the country has brought unprecedented opportunities for the development of COB downlights.

Radio Modem

Radio modems are dedicated to transfer data between two or more locations. GrandComm`s radio modems operate in VHF and UHF frequency band and can cover a distance of over 50 kilometers. The radio modems can provide programmable serial baud rates from 1200bps to 115200bps.

GrandComm`s radio modem products are designed to industrial standards and well-suited for SCADA,  telemetry and process control applications in wireless environment. The radio modem can communicate data of remote control signals, telemetry signals from a transducer, computer`s RS232 port, GPS position signals, or a digital terminals.
