Increase promotion efforts, so that more consumers understand the advantages of LED energy-saving lamps, change their understanding of the concept of energy-saving products; Continuously improve the production process, reduce the price of products, so that more ordinary families can use LED energy-saving lamps. As long as these problems are solved, we believe that China’s LED energy-saving lamp industry will usher in new development opportunities. LED frequently asked questions, LED running dark for a while, is the current flowing through the switching power supply lead is too large, can check whether the total current of the lead exceeds the switching power supply output current value. If so, replace the power lead.
Unit, Candlelight (CD), Luminous flux: the sum of the amount of visible light emitted by a light source per second. Unit, Lumens. Luminous efficiency is the luminous flux emitted by the light source divided by the power of the light source. It is an important index to measure energy saving of light source. Units, lumens per watt (Lm/ W). LED color rendering, the degree of light source to the object, that is, the degree of color fidelity. It’s usually called the “color rendering index” unit, Ra.
Is this the false propaganda of the business? Buyers feel like they’ve been ripped off by the LED energy saving trend. In order to find out whether the LED energy-saving lamp in the end is energy-saving, we should first understand the operation principle of LED lamp is what, and what is the difference between it and our traditional incandescent lamp? When it comes to lighting, we are most familiar with the incandescent lamp. Incandescent lamps emit light by converting electrical energy into light energy through the thermal effect of an electric current under current conditions.
Commercial advertising not only for sports events icing on the cake, but also for the event to create more value; Live fan interaction can be shown, bringing the atmosphere to a climax. In fact, LED display is not a “one-shot sale”, before installation and use, according to the product use environment and purpose to select materials according to local conditions, on-site installation and debugging should also be excellence, normal operation of the LED screen also needs perfect after-sales service.
SMD (Surface Mounted Devices) refers to the surface mount packaging structure LED, mainly PCB board structure LED (Chip LED) and PLCC structure LED (TOP LED). The following from the packaging materials to introduce some of the current domestic basic development status. LED stand, The role of the support. PLCC (Plastic Leaded Chip Carrier) bracket is the carrier of SMD LED devices, which plays a key role in the reliability and light performance of LED.
