The present invention relates to a light, in particular to a detachable panel light for working.
Light emitting diodes (LEDs) are solid state devices that convert electric energy to light and generally comprise one or more active regions of semiconductor material interposed between oppositely doped semiconductor layers. When a bias is applied across the doped layers, holes and electrons are injected into the active region where they recombine to generate light. Light is produced in the active region and emitted from surfaces of the LED.
In general, the lighting apparatuses assembled on ceilings or on the light-gauge steel frame of the building are provided with fixed-type light fixtures, a plurality of fluorescent light tubes is assembled to the light fixture, and the light fixture is then embedded in a window formed by the crossed T-grids of the light-gauge steels. However, the fluorescent light tubes have inefficient lighting performance, the heat generated by the fluorescent light tubes cannot be dissipated efficiently by the light fixture, and the light concentrating structure formed by the fixed-type light fixtures is complicated, resulting in increasing the cost for manufacturing the light apparatus.
Troffer-style fixtures are widely used in commercial office and industrial spaces throughout the world. Troffers may be mounted to or suspended from ceilings. Often the troffer may be recessed into the ceiling, with the back side of the troffer protruding into the plenum area above the ceiling.
In a conventional troffer, thin and long fluorescent light tubes with lengths slightly shorter than a length of the troffer are received. The conventional troffer is not energy-efficient and has higher working temperature. Therefore, LED troffers are developed to have energy-saving feature and lower working temperature. The fluorescent light tubes in the conventional troffer are separated rather than modularized. Hence, the replacement and the repair for the light tubes are not convenient. Therefore, how to solve these problems is an issue.
The detachable panel light is a lighting apparatus assembled to the ceilings, the detachable panel light is provided with detachable and modularized LED power and light sources, and the light emitting members are attached on the outer casing by magnetic members. Therefore, the maintenance and the replacement for the LED modules can be convenient.
A middle portion of the detachable panel light has a detachable covering plate. The detachable covering plate covers a power supply. The detachable covering plate is fixed with a safe and hangable safety rope. Therefore, during the replacement or repairing, the detached detachable covering plate can be hung and not fall down the ground. Hence, the replacement or repairing can be achieved in a convenient manner. That is, a user can repair the LED light source by himself or herself, without a step for putting the detachable covering plate 20 by others.
The light emitting members are designed for being transported conveniently. The light emitting members can be packed separately after being detached. Alternatively, several light emitting members can be stacked with each other and packed together to reduce the volume of the package and to reduce the delivery cost.
The panel light comprises an outer casing and a plurality of light emitting members. The outer casing comprises a receiving groove. The outer casing comprises a detachable covering plate assembled at the receiving groove and a plurality of holding members respectively assembled at two sides of the detachable covering plate. Each of the holding members is attached on an inner surface of the receiving groove of the outer casing by a magnetic member. The light emitting members are assembled in the receiving groove of the outer casing. Each of the light emitting members comprises a supporting frame assembled with the corresponding holding member, a light source plate assembled on the supporting frame, and a lightshade assembled on the supporting frame to cover the light source plate.
In some embodiments, the outer casing comprises a fixing frame assembled in the receiving groove and covered by the detachable covering plate.
In some embodiments, the outer casing comprises a safety rope. One of two ends of the safety rope is fixed with the detachable covering plate, and the other end of the safety rope is fixed with the fixing frame.
In some embodiments, the outer casing comprises a power supply assembled in the receiving groove and covered by the detachable covering plate.
In some embodiments, the outer casing comprises a cable component assembled in the receiving groove and covered by the detachable covering plate.
In some embodiments, each of the light emitting members comprises a plurality of side covers respectively assembled at two ends of the corresponding supporting frame.
In some embodiments, the outer casing comprises a plurality of cable through holes and a plurality of ring components respectively fixed on the cable through holes.
