Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application in Presentation] The present invention relates to a lighting device, and relates to three fixtures in which a plurality of discharge lamps are arranged one above the other.

[Conventional technology]

This kind of conventional lighting equipment equipped with a plurality of discharge lamps uses a glow lamp and has a structure in which it is lit using a glow scooter method. Since this conventional lighting equipment uses a glow lamp as a lighting method, the opening angle of the discharge run 1 is slow to start.

Therefore, an instant lighting method was adopted that uses an electronic starter to turn on the lights instantly. However, in order to light multiple discharge lamps using the instant lighting method,
The problem was that it was expensive.

C Problems to be Solved by the Invention] For this reason, there is a lighting device that lights up a plurality of discharge lamps by using both an instant lighting method using an electronic starter and a glow lighting method using a glow lamp. it was thought. However, in a lighting device equipped with multiple discharge lamps, if the discharge lamps arranged on the F side are lit using the glow lighting method, the startup time will be long, and the discharge lamps on the upper side will be lit first. The upper discharge lamp will be in the shadow of the lower discharge lamp, causing a loss in illuminance, so the lower lamp will light up about 2 to 3 seconds later than the upper discharge lamp. When the lamp is turned on, the illumination intensity of the lower discharge lamp becomes high, causing a problem in which a change in brightness occurs that can clearly determine the difference in lighting time.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a lighting device in which the emission lamps arranged on the lower side are lit first, so that the brightness does not change at the time of startup.

[Technical means to solve problems]

The lighting device of the present invention is configured by vertically arranging a plurality of discharge lamps including discharge lamps lit by an instant lighting method and TIi electric lamps lit by a glow lighting method,
The present invention is characterized in that the discharge lamps that are lit using the instantaneous lighting method are arranged below the TIl electric lamps that are lit using the glow lighting method.

[Function] In the lighting device of the present invention, when a plurality of discharge lamps are energized at the same time, the discharge lamps arranged on the lower side are started first using the instant lighting method, and then the discharge lamps arranged on the upper side are started using the glow lighting method. It is started and lights up.

(Example) 1 The configuration of an example of the present invention will be explained with reference to the drawings.

Reference numeral 1 denotes the main body of the device. Inside the main body 1, instant lighting circuit parts such as a ballast 2.3 and an electronic stark circuit 4 connected to one of the ballasts 2 are housed and fixed. A socket 6 for a glow lamp 5 which is connected to the ballast 3 and forms a glow lighting circuit is attached to the socket 6 of the glow lamp 5, which is connected to the ballast 3 and forms a glow lighting circuit. A socket 1 connected to a lighting circuit 7 and connected to a base 9 of one tubular discharge lamp 8
0 and the other tube-shaped discharge lamp 12 connected to a glow lighting circuit 11 consisting of the ballast 3, glow run 15, etc.
A socket 14 connected to the base 13 of the socket 14 is led out by a cord.

Further, on the lower surface of the main body 1, a support part 15 for supporting the tube-shaped discharge lamps 8, such as the fluorescent lamps, which are arranged on the lower side and connected to the instantaneous lighting circuit 7, is formed in the lower part, and the support part 15 is arranged in the upper part. A plurality of elastic supporting pieces 17 each having a supporting portion 16 for supporting a tubular discharge lamp 12 such as the fluorescent lamp connected to the glow lighting circuit 11 are attached thereto.

Further, on the lower surface of the main body 1, a pull switch 18 is provided to open and close the instantaneous lighting circuit 7 and the glow lighting circuit 11 so as to energize them simultaneously, and a pull string 19 for operating the switch 18 is distributed downward. .

Then, a socket 10.14 is connected to each cap 9.13 of the lamp 8.12 supported on the support piece 17, respectively.

Furthermore, four shades 20 are removably attached to the main body 1 to cover the discharge lamps 8 and 12 supported by the support pieces 17. Furthermore, this main body 1 is suspended and supported by a hanging eye 21 such as a ball chain.

Next, the operation of this embodiment will be explained.

Instant lighting circuit 7 and glow lighting circuit 1 are activated by switch 18.
1 is closed at the same time, the lower discharge lamp 8 is lit by the instant lighting circuit 7 before the upper filtration lamp 12, and the upper discharge lamp 12 is lit by the glow lighting circuit 11 with a delay of about 2 to 3 seconds. It will be lit. Therefore, the ti'i electric lamp 12 is turned on after the lower discharge lamp 8 is turned on, and the illuminance of the upper discharge lamp 12 becomes a shadow of the lower discharge lamp 8, resulting in a large illuminance difference. For,
Even if the upper discharge lamp 12 is turned on with a delay, no extreme change in illuminance occurs.

Note that the discharge lamps 8 and 12 are not limited to lamps with the same power capacity, and when using lamps with different power capacities, the discharge lamp with a larger power capacity is turned on in an instant lighting method. Arrange at the bottom.

(Effects of the Invention) According to the present invention, in a lighting device that combines a plurality of discharge lamps and simultaneously energizes the plurality of discharge lamps, the discharge lamps arranged on the lower side are instantaneously lit. At the same time, the discharge lamps arranged above are lit using a glow lighting method, so even if the lower discharge lamps are lit first and the upper discharge lamps are lit later, there is no extreme problem. There is no change in illuminance, there is no unnaturalness caused by different starting methods, and the lower discharge lamp lights up instantly to maintain a certain level of illuminance.Moreover, it reduces the need for expensive instantaneous lighting equipment, making it inexpensive. 1
It's because I'm being asked.
