At the same output power, the drive current required for high voltage LEDs is much lower than for low voltage LEDs. For example, the high-voltage blue 1WLED of the crystal photoelectric photoelectricity has a forward voltage drop of up to 50V, that is, it can output 1W power with only 20mA driving current, and a normal forward voltage drop of 3V 1W LED requires 350mA driving current. In order to output 1W power, the high-voltage LED with the same output power dissipates much less power than the low-voltage LED during operation, which means that the cost of the heat-dissipating aluminum casing can be greatly reduced.
High-voltage LEDs can significantly reduce AC-DC conversion efficiency losses. Taking 10W output power as an example, if a 1W high-voltage LED with a forward voltage drop of 50V is used, the output can be configured in 2 and 4 strings, and the forward voltage drop of 4 series LEDs is 200V, which means only from the city. Electric 220V AC (AC) can be bridged and reduced by 20V. But if we use a 1W low-voltage LED with a forward voltage drop of 3V, even 10 strings with a forward voltage drop is only 30V, which means that it needs to be stepped down from 220VAC to 30VDC. We know that the lower the input and output voltage difference, the higher the conversion efficiency of AC to DC. It can be seen that if high voltage LED is used, the efficiency of the transformer can be greatly improved, which can greatly reduce the power loss during AC-DC conversion. A reduced heat consumption can further reduce the cost of the heat sink.
Therefore, if high-voltage LEDs are used to develop LED general-purpose lighting products, the overall power consumption can be greatly reduced, thereby greatly reducing the design requirements for the heat-dissipating casing. For example, we can meet the heat-dissipating requirements of LED lamps with a thinner and lighter aluminum casing. Since the cost of the heat-dissipating aluminum casing is one of the main cost components of the LED lighting fixture, the effective reduction of the cost of the aluminum casing also means an effective reduction in the cost of the overall LED lighting fixture. It can be seen that the high-voltage LED can bring about an effective reduction in the cost and weight of the LED lighting fixture, but its more important significance is to greatly reduce the design requirements for the heat dissipation system, thereby effectively clearing the maximum entry of the LED lighting fixture into the indoor lighting market. Technical barriers. Therefore, high-voltage LEDs will dominate the future LED general lighting market.
Smart solar outdoor light with both lighting and RGB colorful lighting, can be charged with USB and solar panel. Once it has sunlight, the solar panel can be automatically charged , the charging way is very environmentally friendly. We added a USB charging way so that it can be quickly charged via the USB cable in cloudy day or rainy day.
The outdoor light is solar-sensing, it will automatically turns off when in the bright enviroment, then begin to charge by solar. When the night comes, it will automatically turn on in the dark. Waterproof IP65 makes users no need to worry when using in the rainy day.
Equipped with a detachable plastic sticker, it can be used to decorate the lawn, garden, beach... After removing the plastic sticker, it can be placed on the table as an ambient light. They will be stars fall into your garden, twinkle in the dark and go off in the day. Automatic cycle colorful mode makes parties begin at anytime and anywhere.
Our LED products can meet global quality standards and pass European testing by TUV Rheinland. Bulbs have certifications such as EMC, RED, LVD, ROHS, REACH, ERP and FCC.
The App are developed on the most advanced Bluetooth Mesh technology. [LinkupHome" App can be downloaded in the App store or Google Player, then you can control our product without any complicate steps. The App is stable, easy control and multifunctional.
The advantages of Bluetooth Mesh are fast connect, low power consumption, no password required and Ad-Hoc Network. No need WIFI and hubs, as long as you have a Bluetooth-enabled smart phone, you can experience the smart light. When you install several smart solar lamps, the self-organizing network function can make the signals free connect, break the limitation of distance.
