Abstract

PURPOSE:To inhibit the lighting of a power failure lamp even during a power failure when the environment is bright particularly by arranging a photoconductive element for controlling the lighting of the power failure lamp by sensing the brightness of the environment at the rear from the aperture edge of a reflector. CONSTITUTION:A photoconductive element 14 controlling the lighting of a power failure lamp 7 by sensing the brightness of the environment is fitted in a recess 15 bored on a mount 5 covered by the cover face 11B of a light transmission plate 11 provided in front of a stanchion 6 and is covered with the cover face 11B covering the upper aperture of this recess 15. Accordingly, when the environment is bright, the power failure lamp 7 is not lighted even during a power failure or under a power failure condition when a power plug is drawn from the power supply, thus preventing the power waste such as the dissipation of a secondary battery. In addition, the photoconductive element 14 is located backward from the aperture edge of a reflector 12, thereby the power failure lamp 7 can be prevented from being turned on or off frequently.

Description

[Detailed Description of the Invention] The present invention relates to a configuration of an electric fan that incorporates a power outage light that is turned on during a power outage, etc., and is designed to prevent the power outage light from turning on even if there is a power outage, especially when the surrounding area is bright. It is something.

Conventionally, there is a type of Taifu-style machine equipped with lighting inside, but pp
It was of no use during times of the year, and it was very dangerous if there was a power outage at night or in a dark room. For this reason, it has been considered that IaJIL machines may be equipped with power outage lights, which can be turned on during power outages and used as footwell lighting.

However, when the surroundings are dark, such as at night, the 7'' larva is able to achieve its intended purpose, but it is difficult to unplug the 7'' larva from the power outlet in order to move between rooms or in a brightly lit room. In the event of a power outage, all power outage lights are turned on even though they are not necessarily turned on, resulting in wasted power and inconvenience.

The present invention has been made in view of the above points, and a photoconductive element is provided in an electric fan equipped with a power outage light, so that when the chest circumference exceeds a predetermined brightness, the power outage light is turned on by the power outage light itself. A power outage light that operates by sensing the lighting of a machine, etc., which does not blink frequently, is arranged at a position farther away from the opening of the reflector of the electric light, and by using such a structure, the surrounding It is safe and economical because it lights up during a power outage when it is dark and does not turn on when it is bright.

Embodiments of the present invention will be described below with reference to the drawings.

! The installed photoconductive element α4 is located behind the lower part of the opening edge on the side of the first reflecting plate, so that when the power outage light (7) is turned on, a light beam is irradiated through the first reflecting plate (b). is avoided.

The frame of the present invention is constructed as described above, so when the surrounding area is bright, the power outage is 11vFe, and even if the power supply defuger is unplugged from the power supply and a power outage occurs, the power outage light will not turn on, and the power will be saved by preventing consumption of the secondary battery. There will be no waste. Moreover, the photoconductive element is located behind the opening edge of the reflector, so when the power outage light is turned on, it does not sense the light from the power outage light and operate, so the power outage light does not turn on frequently. . Furthermore, since it is covered with a transparent plate, dust may adhere to the photoconductive element.
