LED lighting features

LED lighting products are a new generation of lighting trends, with green environmental protection and energy saving features. The products are divided into two series: public lighting and indoor lighting. The public lighting series includes LED street lights , LED tunnel lights and LED flood lights , which can be used for residential, street, road and floodlighting. Indoor lighting includes LED downlights , LED fluorescent lights, LED grille lights, LED bulbs, suitable for indoor lighting places in home, business, institutions, schools, military, hospitals, aerospace, etc., as well as holiday lighting , parks, stage, etc. It can generally replace traditional chandeliers, downlights, fluorescent lamps, light bars and other lamps.

With the continuous development of LED lighting fixtures, high-brightness LEDs have shown strong growth momentum in more and more general lighting fields. Due to the strong domestic lighting demand, the market attention of brightness LED is gradually strengthening, and the promotion of various large-scale events has also enabled China to continue to grow into the largest market for high-brightness LED applications. The Kongming luminaire developed by Dongguan Huachen Optoelectronics Technology Co., Ltd. is the leader in this huge industry competition.

LED lighting features:

1. Energy saving. Using a high-quality LED light source, 1W of light is equivalent to 4-5 times that of incandescent lamps under the same electric energy, and is more than twice that of energy-saving lamps.

2, environmental protection. LED is a semiconductor material, without any harmful substances, and can be recycled because it is solid and not brittle.

3, long life. The life expectancy of LED lamps is generally more than 5 times that of energy-saving lamps under normal use.

4, the light color is pure. LED color rendering index (RA) is higher than traditional lamps, generally reaching more than 75, the traditional lamp is about 40-50.

5, can work in high speed state. If the energy-saving lamp starts or turns off the filament frequently, it will black out quickly. The LED belongs to the semiconductor and can work in the high-speed switching state.

Optical Line Terminal (OLT)

POE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. Etc.) The technology that can provide DC power for such devices while transmitting data signals is a switch that supports Power over Ethernet.

POE is also known as a power supply system based on local area network (POL, Power over LAN) or Active Ethernet (Active Ethernet), sometimes also referred to as Power over Ethernet for short. This is the use of existing standard Ethernet transmission cables to transmit data and data at the same time. The latest standard specification of electric power, and maintains compatibility with existing Ethernet systems and users. The IEEE 802.3af standard is a new standard based on the POE of the Ethernet power supply system. It adds related standards for direct power supply through the network cable on the basis of IEEE 802.3. It is an extension of the existing Ethernet standard and the first international standard for power distribution. standard.
IEEE began to develop the standard in 1999, and the earliest participating vendors were 3Com, Intel, PowerDsine, Nortel, Mitel and National Semiconductor. However, the shortcomings of this standard have been restricting the expansion of the market. Until June 2003, the IEEE approved the 802.3af standard, which clearly stipulates the power detection and control items in the remote system, and connects routers, switches, and hubs to IP phones, security systems, and wireless LANs through Ethernet cables. The method of power supply for points and other equipment is regulated. The development of IEEE 802.3af includes the efforts of many company experts, which also allows the standard to be tested in all aspects.
The IEEE 802.3at standard was formulated in 2005 and promulgated in 2009. The 802.3at standard output power can reach 30W, and the available power at the receiving end is 25.5W.
The IEEE 802.3 working group and various manufacturer alliances launched POH-POWER OVER HDBASET in the industry at the end of 2012.
Using the current 4-Pair four-pair wire technology plus, the bilateral power supply can reach 60-100W power, which can be achieved by using 5 or 6 types of wires. It is used in high-definition video promotion to supply power to 42" LED TVs. According to the new regulations in 2010, the power consumption of 42" LED TVs needs to be less than 70W.
