USA - SemiLEDs ( http:// ) launched the P5 UV LED, a new high power 5W 365nm UV LED in a silicon casing in ready to use format. With this significant achievement, SemiLEDs becomes one of the only LED Chip producers to provide a high power 365nm UV LED, once again proving itself as a pioneer in the LED industry.
The launch of the P5 UV LED has positioned SemiLEDs not only as a leading LED chip manufacturer but also as the premier UV LED provider.
SemiLEDs P5 UV LEDs are made using its patented vertical MvpLED10 chips which feature a copper-alloy base in a silicon casing with a UV glass encapsulation. The advantages of SemiLEDs MvpLED10 chips are delivered through these unique features as the copper-alloy base and silicon casing Allow for maximum heat transfer from the junction to the board or heat sink, a crucial element to optimizing the lifetime of the UV LED.

UV LEDs have had a growing impact on a large and diverse group of UV market segments such as curing, currency/document verification, tanning, medical and sterilization. The benefits of UV LEDs over traditional mercury lamps are illustrated through their flexibility, compactness, cost Effectiveness and absence of mercury, a notorious pollutant.
UV LEDs are greatly enhancing applications in UV market segments and with UV LEDs poised to replace traditional UV lamps, a wide array of new applications are expected to further drive the UV LED market in the future.
Leakage protector, also known as leakage switch, is a new type of electrical safety device, mainly used for:
(1) Prevent electric shock accidents caused by electrical equipment and electrical circuit leakage;
(2) Preventing single-phase electric shock accidents during electricity use
(3) Timely cut off single-phase grounding faults in the operation of electrical equipment to prevent fire accidents caused by leakage
(4) With the improvement of people's living standards and the continuous increase of household appliances, personal electric shock and fire accidents caused by defects, improper use, and inadequate safety measures of electrical equipment in the process of using electricity have brought undue damage to people's lives and property. The emergence of leakage protectors provides reliable and effective technical means for preventing various accidents, timely cutting off power, and protecting equipment and personal safety.
The leakage protector should meet the following technical requirements
(1) The sensitivity of electric shock protection should be correct and reasonable, and the starting current should generally be within the range of 15-30 milliamperes
(2) The action time of electric shock protection should generally not exceed 0.1 seconds
(3) The protector should be equipped with necessary monitoring equipment to prevent it from losing its protective effect when the operating state changes. For example, for voltage type electric shock protectors, a neutral grounding device should be installed.
