Abstract

PURPOSE:To enable the downsizing by lowering height dimension of an equipment, and also diminish thermal influence upon an electric power supply battery exerted by a charging transformer. CONSTITUTION:A reflector 31 opposing to a lamp 33 installed in a lamp socket 30 is arranged so as to front on a radiating opening 12 of an equipment body 11. A lighting circuit unit 20 provided a charging transformer 27 on one side is arranged in a position near a terminal stand 16 arranged in a position above the reflector 31. An electric power supply battery 36 is arranged in a position on the other side of the lighting circuit unit 20. Heat of the charging transformer 27 having a large calorific value is released to the equipment body 11. A temperature of the electric power supply battery 36 is hardly raised by the heat of the charging transformer 27. The whole equipment can be assembled compactly by lowering the height dimension.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of an embodiment of the present invention will be described with reference to FIGS.

In FIG. 1, 11 is a substantially cylindrical instrument body having an irradiation opening 12 opened on the lower surface thereof, which is directly attached to the ceiling surface or embedded and fixed.
Inside the top plate 13 of the device main body 11, a terminal block 16 having a power source connecting portion 15 exposed in a window hole 14 formed in the top plate 13 is attached. The power line can be connected.

A lighting circuit unit 20 is incorporated in a unit case 21 molded of synthetic resin. A circuit board 22 is horizontally arranged and housed in the unit case 21, and an electric component 23 forming a lighting circuit and a charging circuit is connected to the circuit board 22. The upper surface of the unit case 21 is opened and is closed by the top plate 13. A fitting hole 24 for fitting and arranging the terminal block 16 is formed in the circuit board 22, and the lighting circuit unit 20 is provided with the terminal block 16 by arranging the terminal block 16 in the fitting hole 24. The lighting circuit unit 20 and the terminal block 16 are electrically connected to each other.

The unit case 21 of the lighting circuit unit 20 is integrally formed with a transformer accommodating portion 26 bulging downward to one side, and the transformer accommodating portion 26 is provided with the circuit board.
A charging transformer 27 connected to 22 is stored and fixed.
When the unit case 21 is housed in the instrument body 11, the end face of the transformer housing portion 26 is brought close to the inside of one side surface of the instrument body 11 to radiate heat to the instrument body 11.

A lamp mounting window hole 29 is formed in the center of the lower surface of the unit case 21.
A lamp socket 30 having a lamp mounting surface facing 29 is fixed in the unit case 21. A reflector 31 is disposed in the center of the lower surface of the unit case 21 so as to face the lamp mounting window hole 29, and an irradiation opening 32 of the reflection plate 31 faces the irradiation opening 12 of the instrument body 11. Further, the lamp 33 detachably mounted in the lamp socket 30 through the lamp mounting window hole 29 is enclosed in the reflector 31.

Further, 35 is a battery case.
35 is formed in a substantially arc shape so as to embrace the unit case 21, and the battery case 35 faces the charging transformer 27 housed in the transformer housing portion 26 of the unit case 21 and other parts of the lighting circuit unit 20. It is located on the side and is housed in the instrument body 11. Further, the battery case 35 accommodates a power battery 36 connected to the lighting circuit unit 20.

The reflector 31 is disposed in a space recess 40 formed in the lower center of the battery case 35 and the transformer housing 26 of the unit case 21.

Next, the operation of this embodiment will be described.

When the battery case 35 is tied to the unit case 21 and housed in the instrument body 11, the power supply battery of the battery case 35
36 is opposed to the transformer housing portion 26 of the unit case 21 with the unit case 21 interposed therebetween, the power supply battery 36 and the charging transformer 27 are separated from each other, and the charging transformer 27 is brought close to the instrument body 11. Then, when the top plate 13 is covered on the upper surface of the instrument main body 11 and fixed to the instrument main body 11, the terminal block 16 attached to the top plate 13 is attached.
Is fitted into the fitting hole 24 of the circuit board 22, and the lighting circuit unit 20 is arranged around the terminal block 16.

In the device thus assembled, the charging transformer 27 of the lighting circuit unit 20 and the power supply battery 36 are arranged on the left and right sides with the lighting circuit unit 20 interposed therebetween, and further, the lighting circuit unit 20. Is disposed around the terminal block 16, and the reflector 31 is disposed in the space recess 40 formed by the transformer housing portion 26 and the battery case 35, so that the height of the entire apparatus is reduced and the apparatus is compactly assembled.

When power is supplied from the power supply line connected to the terminal block 16 of the installed equipment, the power supply battery 36 is charged from the charging circuit of the circuit board 22 via the charging transformer 27. In this state, even if the charging transformer 27 generates heat, since it is separated from the power supply battery 36, the heat of the charging transformer 27 is dissipated at the end of the device body 11 and the temperature of the battery case 36 is raised. Therefore, the life of the power supply battery 36 due to temperature rise is not shortened.

In this state, if the power supply is interrupted due to a power failure or the like, the discharge circuit of the circuit board 22 performs a switching operation to discharge the battery 36, the lamp 33 is turned on, and the reflector 31 reflects it. Then, the light is emitted from the light projecting opening 32 opened at the lower part, and the floor surface is illuminated from the light projecting opening 12 of the instrument body 11 while maintaining a predetermined illuminance.

[0021]

According to the present invention, since the charging transformer of the lighting circuit unit is arranged on the side opposite to the power source battery, the heat of the transformer, which generates a large amount of heat, is easily dissipated to the main body of the appliance, and the heat for the power source battery is In addition, since the charging transformer of the lighting circuit unit and the power supply battery are arranged on the left and right, and the lighting circuit unit is arranged around the terminal block, the entire equipment can be assembled compactly, The height dimension can be reduced and the size can be reduced.
