东芝照明室外白光LED功耗仅白炽灯20%

October 22, 2023


东芝照明技术开发出主要设想在室外应用的LED照明产品，并在2008年3月4～7日东京有明国际会展中心举办的“街道装饰流通复兴”特别展“LED Next Stage”上展出。目标是代替该公司销售的称为“Beam Lamp”的白炽灯。Beam Lamp主要用于在夜间照射室外的看板。使用新开发产品，能够较白炽灯削减功耗。例如，使用交流100V的电压驱动时，该公司原来的白炽灯需耗费69W，而新开发产品在相同亮度时只需15W即可。该公司此前开发了使用白色LED的照明产品，此次为了能在室外使用，提高了耐水性等环境适应能力。

新开发产品的寿命为，亮度降至70%的时间为2万小时，相当于该公司白炽灯Beam Lamp的2.5倍左右。此次，开发了色温分别约为3000K、5000K的两种产品。目标是2008年内投产。预计市场价格为1万日元左右，是该公司销售的白炽灯Beam Lamp建议零售价(1890日元)的5倍多。虽然价格高，不过长时间使用“Beam Lamp照明的话，电费不可低估。新产品在这一点上颇具魅力”。

High Voltage Linear Power Supplies

HVLP series Linear High Voltage Power Supplies are High-voltage DC Power Supplies that achieve AC/DC conversion through power frequency transformers and transistor loop control. Compared with switching high voltage power supplies, linear high-voltage power supplies have higher stability, higher accuracy, and lower output ripple. And the most important, because of the use of the power frequency AC/DC conversion principle, the linear power supply has no high-frequency radiation interference, and it is especially suitable for use in places with restrictions on EMC and EMI.


High Voltage Linear Power Supplies


The HVLP series Linear Power Supplies have a wide range of output specifications, the output power ranges from 1KW to 400KW, and the output voltage can reach up to 50KVDC, and accept customization.

The whole series linear power supply adopts industrial-grade metal chassis, pure copper AC/DC multi-insulation high-voltage transformer with varnish treatment, high-reliability multi-transistor filter loop, ensuring the power supplies can run for a long time at full load with high stability, high accuracy, and ultra-low ripple electronic characteristics, equipped with a complete protection circuit, which can better ensure the reliability of the linear power supply itself and the safety of the customer's load.
The output voltage and current can be adjusted by the 10-turn potentiometer with scale and lock on the front, equipped with 4 1/2-digit high-resolution LED meters for output value reading, and RS communication interface can also be added for remote control and monitoring of linear power supplies.

This series of linear high voltage power supplies are mainly used for gas discharge, high-voltage electronic tubes, and can also be applied for other electronic components burn-in test.
Because the output this power supply has HV, the output MUST be connected to the chassis for fixed grounding to ensure the personal safety of the user.
