PORTABLE HIGH POWER AC LIGHTING

摘要

A portable high power AC lighting comprises a body with an opening at the top thereof, a bulb holder disposed inside the opening, an AC bulb above the bulb holder, a light cover fixed above the opening for covering the AC bulb, and a control circuit board disposed therein for recharging and saving the direct currents rapidly and repeatedly in the series lithium battery pack to provide the AC power for the AC bulb by an AC supply unit, forming an AC lighting device of high-brightness with a 360° lighting angle that can be held and carried easily like a bright torch. Also, the present invention uses a standard AC LED/PL bulb which is common in households, making it much easier to replace the bulb when needed. Hence, the present invention has the problems in the prior art solved and provides a high power but energy saving lighting device for continuous usage.

主权项

1. A portable high power AC lighting, comprising
a body arranged in a shape for holding with an installing space therein and an opening at the top thereof; a series lithium battery pack including a plurality of lithium batteries and disposed inside the installing space; at least one controlling circuit board disposed inside the installing space and electrically connected to the series lithium battery pack with a DC charging unit and an AC supply unit disposed thereon; a DC power input interface coupled to the controlling circuit board and arranged on the surface of the body uncovered; a bulb holder disposed inside the opening of the body and electrically connected to the controlling circuit board; an AC bulb, including a cap and a luminous body where the cap being mounted on the bulb holder, placing the luminous body above the opening and the AC bulb above the body; a light cover fixed above the opening in order to cover the AC bulb; said DC charging unit including a charging control loop with the input thereof coupled to the DC power input interface and a MCU coupled to said charging control loop with the positive and negative electrode of the series lithium battery pack separately coupled to the charging control loop and the MCU; and said AC supply unit including an output control loop with the input thereof coupled to the charging control loop and the positive electrode of the series lithium battery pack and coupled to the MCU as well for the output control loop to control the output of the direct currents, and a DC-AC converter with the input thereof coupled to the output control loop to convert direct currents to alternating currents and further provide the electricity for the AC bulb from the output terminal thereof; whereby the series lithium battery pack can restore DC energy and provide the electricity for the AC bulb via the AC supply unit, so as to form a portable high power AC lighting with a 360° lighting angle.
