Power-off protector and lighting device using same

Abstract

The invention is applied to the technical field of power-off protection, disclosing a power-off protector and a lighting device using the same. The power-off protector comprises a first basal lamina and a second basal lamina, wherein the first basal lamina is fixedly provided with a draw bar, the second basal lamina is movably sheathed on the draw bar, and a first elastic member is arranged between the first basal lamina and the second basal lamina; and one side of the first basal lamina opposite to the second basal lamina is fixedly provided with a first conducting strip, and one side of the second basal lamina opposite to the first basal lamina is fixedly provided with a second conducting strip which can be contacted with or separated from the first conducting strip. The lighting device comprises a shell component and a luminous component, wherein the luminous component is fixedly arranged in the shell component; and the shell component comprises an upper shell and a lower shell and is internally provided with a power-off protector. The power-off protector and the luminous device using the same provided by the invention have the characteristics of small volume, simple and easy installation and good reliability.

Description

technical field [0001] The invention belongs to the technical field of power-off protection, and in particular relates to a power-off protection device and a lighting device using the power-off protection device. Background technique [0002] In lighting devices, especially those using double-ended HID light sources, because the connecting wires at both ends of the light source are exposed at the outer ends, when replacing the light source, people may touch the charged body, so a power-off protection device must be installed. In order to prevent electric shock when changing the light source and avoid causing safety accidents. The currently commonly used power-off protection device basically adopts a plug-in structure, which includes a first substrate and a second substrate. The first substrate is fixed to the upper shell of the lighting device, and the second substrate is fixed to the lower shell of the lighting device. , the wires are all connected to the terminals on the ...

AI Technical Summary

Problems solved by technology

In such a structure in the prior art, all the wires are connected to the second substrate, which causes the overall volume of the second substrate and the device to be too large, which is not conducive to the installation of the product; and the first substrate and the second substrate need to be respectively fixed on the upper shell and the lower shell. On the shell, the installation is complicated, and the precision is high, and the reliability is poor; in addition, in the power-off protection device in the prior art, the contact between the conductive sheet and the terminal is a rigid contact, and such a structure requires high dimensional accuracy of the product. , when the tolerance of the corresponding structure of the product is large, it is easy to cause failure or damage of the power-off protection device

The first substrate and the second substrate in the power-off protection device are generally made of plastic materials, which have poor thermal conductivity and heat resistance, and are easy to deform, especially when the heat generated by each conductor itself is large, because the heat cannot Derived in time, the temperature of the first substrate and the second substrate will continue to rise, eventually causing deformation or even burning, and the reliability of the product is poor
