Description

Technical Field

[0001] The utility model relates to the technical field of emergency downlights, in particular to a novel emergency downlight. Background Art

[0002] Emergency downlights are lighting fixtures that can be used in some emergency places. This type of downlight is generally installed in the ceiling and is a recessed hidden lighting fixture. It uses a downward lighting method. When the power is normally used, the 220V AC charges the battery inside the emergency downlight, and the bulb does not light up. When the normal power is disconnected, the battery of the emergency lighting lamp is powered and the bulb lights up. The existing technology has the following problems:

[0003] Because the existing emergency downlights are embedded in the ceiling with only the lampshade part exposed, when the lamp beads and other parts in the lampshade need to be inspected and replaced, the entire emergency downlight can only be removed and the lampshade can be pulled out using the snap-on structure for maintenance, which affects the maintenance efficiency. At the same time, when the existing emergency downlights are connected to the power, multiple wires need to be inserted into the interior and connected to the internal battery circuit, but the connection method is often spot welding or tape winding. Once the external circuit is pulled during disassembly and assembly, the internal connection point with the battery is easy to loosen, resulting in the problem of failure to supply power and light up in time.

After the power supply is connected, the knobs 143 on the top of the power connection boxes 14 can be rotated respectively, thereby driving the threaded rod 142 to rotate and making the arc-shaped pressure plate 144 stably move downward under the sliding limit of the slide rod 145, so as to squeeze and fix the wire passing through the wire hole 15, thereby improving the stability of the power wire. When the battery needs to be inspected and repaired, the bolts threadedly connected to the perforated bolt column 17 through the rear cover bolt hole 161 can be removed, and then the rear cover plate 16 can be removed from the rear side of the lamp tube housing 1 to expose the interior of the lamp tube housing 1 for easy maintenance. At the same time, when the battery is charging, the heat dissipation holes 18 can be used to improve the heat dissipation of the battery inside the lamp tube housing 1, which is beneficial to increasing the service life of the battery.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
