LED: A light-emitting diode, also known as an LED light fixture, refers to an appliance that transmits, distributes, and changes the light distribution of an LED source, including all the zeros, components, and other components required to secure and protect the LED light source except the LED light source. The line attachment necessary for the power connection. The quality of LED lamps on the market is uneven. How to choose LED lamps has become an important issue. What application range of LED lamps is also a problem that cannot be ignored. Below I will introduce these two questions for you.
How to choose LED lamps:
First of all, we must know what the core value of LED lamps is. The main advantages of LED lamps are power saving, long life, rich color and fashion.
First, the cost. From the perspective of cost, the price of LED lamps is about 3-10 times that of traditional lamps. If the electricity consumption time is more than 6 hours per day, it is cost-effective to use LED lamps. It is expected that one year will save the purchase. The money of the lamp; if it takes 2-3 hours a day, the electricity bill will not save much.
Second, the value. Of course, people are not all activities for the sake of money. Pursuing fashion and accepting new things is also a life attitude.
Third, the quality. After you've decided to buy LED fixtures, you need to see what quality LED fixtures you need.
Fourth, after sales service. Before buying, it is best to let the agent know how long the LED manufacturer's warranty period for LED lighting products is. Some poor LED lamps are only kept for one year. That is similar to the life of traditional energy-saving lamps. The price is still expensive, it is not worthwhile. .
Five, the other is the choice of product features, such as LED ceiling lights (also called LED spotlights) and LED Geshan lights are concentrated LED lamps, mainly used to highlight the local lighting, according to the requirements of light effects can be customized 5 Lens, 15 degrees, 30 degrees, 60 degrees and other angles of the lens; LED downlights are pan-light source LED lamps, mainly with lighting as the main function; LED lights are mainly auxiliary light effects, compared to ordinary T5 lamps, In addition to saving power, his advantages can also be used in curved places, such as ceilings.
What is the scope of application of LED lights:
(1) The display and communication number display the application of the light source. LED lamps are shock and shock resistant, fast in light response, power saving and long life. They are widely used in various indoor and outdoor displays, and are divided into full-color, two-color and monochrome displays. Traffic lights are mainly used for high brightness. Red, green and yellow LEDs use LED lighting signals to save energy and have high reliability. Therefore, traffic lights are gradually being upgraded.
(2) LED lamps can be used in the automotive industry. The automotive lamps include the interior of the vehicle's instrument panel, audio indicators, switch backlights, reading lights and external brake lights, tail lights, side lights and headlights. LED lamps respond quickly, alerting drivers to brakes early and reducing car rear-end accidents.
(3) LED lamps are used as LCD backlight applications. Long life, high luminous efficiency, no interference and high cost performance have been widely used in electronic watches, mobile phones, BP machines, electronic calculators and credit card machines. With the increasing miniaturization of portable electronic products, LED backlights have more advantages.
(4) LED lighting source replaces traditional lighting fixtures. This replacement trend has begun to involve indoor and outdoor, commercial lighting, road industrial lighting and so on.
(5) Other applications of LED lamps such as electronic products such as mobile phones, digital players, computers, radios, etc. For example, a flashing shoe that is popular with children, the built-in LED will flash when walking.
The network-managed industrial switch literally means a switch that can be managed by the network. There are three management methods, which can be managed through the serial port, through the Web, and through the network management software. It provides a terminal-based control port (Console) and a Web-based page. And support multiple network management methods such as Telnet remote login network. Therefore, network administrators can perform local or remote real-time monitoring of the switch's working status and network running status, and manage the working status and working mode of all switch ports in a global view.
The managed industrial Ethernet Switches all follow the SNMP protocol (Simple Network Management Protocol), which is a set of network equipment management specifications that comply with international standards. All devices that follow the SNMP protocol can be managed through network management software. You only need to install a set of SNMP network management software on a network management workstation, and you can easily manage the industrial Ethernet switches, routers, servers, etc. on the network through the local area network. It is also an in-band management method through the interface of SNMP network management software.
