Abstract

PURPOSE:To reduce the influence of temperature so as to prevent the life of a battery from being shortened by mounting a battery case in a battery installing portion formed between the transformer storage portion and the socket support block portion of a lighting unit case. CONSTITUTION:A battery storage portion 42 is formed between the transformer storage portion 15 and the socket support block portion 22 of a unit case 8. Even if a transformer 41 and heating components of a circuit board 10 are heated, heat convection flowing through the inside of the unit case 8 from the lower face air hole 24 of the unit case 8 to the air hole 16 of the transformer storage portion 15 is generated and heat is radiated from the heating components and the transformer 41 and transferred to an equipment main body 1. Besides, the air hole 16 of the transformer storage portion 15 is located above a battery case 25 and is also open to front side so the temperature of the battery case 25 would not be raised and the life of a battery 27 would not be shortened by temperature rises.

is plugged in and connected.

When this unit case 8 is stored in the instrument main body 1,
Even if the upper surface of the transformer storage section 15 that faces the inner side of the upper surface of the instrument body 1 is brought close to the inner side of the upper surface of the instrument main body 1, and the unit case 8 is tilted and vibration occurs, the upper surface of the transformer storage section 15 will remain on the inner side of the upper surface of the instrument main body 1. The inclination of the unit case 8 is restricted by contacting the terminal block 6, and the connection between the terminal block 6 and the connector piece 14 of the circuit board 10 is prevented from becoming unstable.

In this state, if the power supply is interrupted due to a power outage, etc.
The discharge circuit of the circuit board 1 (l) performs a switching operation to discharge the battery 27, the light bulb 30 is lit, and the reflector 31
The light is reflected by the light and emitted from the irradiation aperture 35, illuminating the floor surface while maintaining a predetermined illuminance. Since the emergency light mini halogen light bulb 30 is integrally equipped with the reflector 31, the relative position of the light bulb 30 with respect to the reflector 31 is reliably maintained.
Illumination with predetermined light distribution characteristics.

In addition, since the light bulb 30 is held in a light bulb holder 32 formed at the center top of the reflector 31 facing inward, it is compared to a structure in which the light bulb 30 is held in a light bulb holder formed at the center top of the reflector facing outward. As a result, the reflective surface is expanded and the reflection efficiency is increased.

In addition, the reflector 31 is a plurality of types of reflectors 31 each having different light distribution characteristics depending on the irradiation height! , 31b.

Equipped with 31c, reflector 31 for high ceilings! If you select the light bulb 30 with
Since the paraboloid of revolution quadratic curved body portion 37 is formed from
The spread of the light emitted from the irradiation aperture 35 is reduced, and the illuminance of the floor surface can be maintained even when irradiated from a high position. In addition, when the reflector 3111 for the middle ceiling is selected, the light bulb holder 32
From the horizontal flat part 36 to the rotating paraboloid quadratic curved part 37
is formed, so that the light emitted from the irradiation aperture 35 spreads like the reflector 31 for high ceilings! The illuminance on the floor can be maintained even when irradiating from a mid-ceiling position.

Furthermore, when the reflector 31c for low ceilings is selected, a parabolic quadratic curved body part 37 is formed from the light bulb holding part 32 through a wide horizontal flat part 36, so that light is emitted from the irradiation opening 35. It has a large spread and illuminates the floor surface over a wide range while maintaining illuminance.
