Description

Technical Field

[0001] The utility model relates to the technical field of emergency lamps, in particular to a circuit board mounting structure of a double-head lamp. Background Art

[0002] Fire emergency lighting is a guarantee for safety and emergency in public places. It is a mandatory equipment for public fire protection. It has a wide range of uses and a relatively complex layout environment. It is usually installed in fire escape passages. When power outages, fire alarms, etc. occur, the lights can be automatically turned on to realize the emergency lighting function.

[0003] The existing fire emergency double-head lamp consists of a light box and a lamp holder. A driving circuit board is provided in the light box, and a light source board is provided in the lamp holder. The driving circuit board and the light source board are electrically connected by wires. The driving circuit board drives and lights up the LED light source on the light source board. The existing light box consists of a box body and a cover body. Since the lamp holder needs to be installed on the box body, in order to facilitate assembly and protect the wires, the circuit board also needs to be installed inside the box body. The common structure is: a mounting portion is stamped on the back plate of the box body, and the circuit board is mounted on the back plate of the box body by using the mounting portion. The cover body with an assembly hole is mounted in the opening of the box body. However, in this structure, the mounting portion will be displayed on the surface of the lamp that is displayed to the outside. In order to make the product more beautiful, it is necessary to set a label to cover it, but this still affects the overall appearance of the product; since the double-head lamps are hung on the wall using assembly holes, and the cover with the assembly holes is a separate metal plate, which is installed on the box using screws or snap devices, when the double-head lamp is in use, the position where the screws or snap devices are installed will bear the force of the entire lamp. Long-term use will cause the product to deform, resulting in a shorter service life of the product; there are also some structures where the back panel of the box is provided with assembly holes and the circuit board is also installed on the back panel, but since the distance between the circuit board and the cover is far, it is difficult for users to observe the indicator lights on the circuit board or difficult to operate the buttons on the circuit board, which cannot meet the national standard requirements.
