Although this kind of warning slogan has a prompting effect, it cannot fundamentally avoid and eliminate the misoperation of maintenance personnel. For some careless maintenance personnel, if they do not pay attention to this warning and still operate with power on, there will be a greater safety hazard

Embodiment Construction
[0015] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0016] The present invention provides a power-off protection structure for opening the cover, which is arranged in a containing space enclosed by a first shell and a second shell of a device to be opened, and includes An electromagnet with a power supply and a magnetic induction element arranged on the second housing and magnetically attracted to the electromagnet. In the present invention, a magnetic element that magnetically attracts each other is arranged between the two shells of the equipment to be opened. In this way, when the power is on, the electromagnet attracts the magnetic induct...

The invention, which is suitable for the power-off protection technology field, provides a protection structure for uncapping in a power off state and a lighting fixture. The protection structure, which is arranged in accommodation space formed by enclosing of a first housing and a second housing of a to-be-uncapped device, comprises an electromagnet that is arranged on the first housing and is conducted with an external power source and a magnetic induction component that is arranged on the second housing and is attracted to the electromagnet. According to the invention, magnetic elements with attracted magnetism are arranged between the two housings of the to-be-uncapped device; therefore, the electromagnet is attached to the magnetic induction component on the power on condition, so that the two housings can not be separated; and when the power is turned off, the two housings are separated. When the provided protection structure is employed, it can be avoided that maintenance personnel carries out operation on the power on condition fundamentally, thereby effectively ensuring personal safety of the maintenance personnel. And application of the protection structure to a lighting fixture enables usage security of the lighting fixture to be enhanced and the product performance to be optimized, thereby improving competitiveness of the lighting fixture.
Description
Technical field [0001] The invention belongs to the technical field of power failure protection, and more specifically, relates to a lighting lamp. Background technique [0002] Various electrical appliances of professional lamps are placed in a closed lamp housing. The lamp housing is generally a bottom housing and a front housing fixed in one body by screws. When the internal electrical appliances of the lamp need to be repaired or replaced, the screw must be removed to open the cover for operation. According to the requirements of relevant safety operation regulations, all the above maintenance operations must be performed after disconnecting the power supply, otherwise the maintenance personnel will have the risk of electric shock. Therefore, there are generally warning signs on professional lamps: Do not operate with power. Although this kind of warning slogan has a prompting function, it cannot fundamentally avoid and eliminate the misoperation of maintenance personnel. ...
