Description

[Detailed explanation of the idea] This idea has a base on the top of the lighting fixture.

This relates to compact fluorescent lighting fixtures aimed at replacing incandescent light bulbs.

Recently, the need for energy conservation has increased, and the demand for small fluorescent lamps as an alternative to incandescent lamps has increased.

Therefore, E2 for incandescent light bulbs specified by JISO7709
In addition to installing a 6-inch metal rod on the top of the fixture body, the lamp is made into a saddle-shaped fluorescent lamp, for example, by folding the U-shaped lamp in half, thereby making the lighting fixture more compact and replacing the incandescent light bulb.

However, when using fluorescent lamps in this way, a glow starter is required to start the lamp, so it is necessary to consider the installation space for the glow starter, which is subject to restrictions on miniaturization, and the glow starter has a relatively short lifespan. Because of this, we are forced to make exchanges easier,
There were drawbacks such as restrictions on the degree of freedom in design.

This invention eliminates the above drawbacks.

An embodiment of this invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a synthetic resin instrument body with a cylindrical body and a flange 2 formed at the bottom of the body.The flange 2 has a recess 4 recessed upward from this surface on the lower surface of the flange 2, and this recess. A lamp socket mounting part 5 including mounting holes 51 provided on both sides of the lamp socket 4 is provided, and at least one of the recesses 4 is provided with a heat dissipation slit 3 communicating with the outside.

Reference numeral 9 designates two lamp sockets (only one is shown) to be installed in the lamp socket mounting part 5, and two lamp socket terminal pins 8 inserted into two lamp terminal pin insertion holes (not shown). Protrude to the back side and attach one lamp socket 9.
An electronic starter consisting of a nonlinear electric element and a semiconductor switch is electrically connected to one terminal pin 8 in close proximity to the back surface of the lamp socket 9.

And the lamp socket 9 to which this electronic starter 7 is connected
is attached to the lamp socket attachment part 5 on the side where the heat dissipation slit 3 is provided.

Reference numeral 19 is a bottom plate attached to the flange 2 so as to cover the bottom surface thereof, 15 is a ballast fixed to the center of the bottom surface of the bottom plate, and 18 is a fluorescent lamp, which is a straight tube-shaped bulb bent into a U-shape. Further, this is folded in half to form a saddle shape, and a lamp cap 20 corresponding to the lamp socket 9 is fixed to both ends of the saddle, and the central part is supported by a lamp holder 16, and is stably attached to the lower surface of the appliance body 1. It is arranged so as to straddle the vessel 15.

Reference numeral 14 denotes an E26m metal plate fitted into the body of the instrument body 1.

In the lighting fixture configured in this way, the lamp 18
When the electronic starter 7 for lighting the lamp is connected to the back side of the lamp socket 9 and the lamp socket 9 is attached to the flange 2, it is hidden by the lamp socket 9. There is no need to provide a starter mounting part, and the diameter of the device body 1 is approximately the same as that of the lamp 1.
It can be made as small as the required planar area of 8.

Moreover, since the electronic starter 7 has a semi-permanent life and does not require replacement, there is no need to expose it to the outside, and restrictions on lighting equipment design are significantly relaxed.

Furthermore, the electronic starter 7 is surrounded by ventilation through the heat dissipation slit 3, and there is no fear that the characteristics will be degraded by heat from the ballast 15 or the lamp 18.

In the above embodiment, two lamp socket mounting parts 5 are provided, and one of them is provided with the electronic starter 7. However, the number of lamp socket mounting parts 5 is limited to two. Generally, one starter is used for one fluorescent lamp 18.

And this idea. An electronic starter 7, which is a type of starter, is placed in front of the heat dissipation slit 3 of the lamp socket attachment part 5.

Moreover, it is arranged in a position hidden in the lamp socket 9, and the lighting fixture itself is made smaller without impairing the characteristics of the electronic starter 7.

Therefore, if the electronic starter 7 itself is provided in the above position, the effect of this invention will be exhibited, so the number of lamp socket mounting parts 5 having heat dissipation slits 3 will be one for every 181 lamps. It's a good thing to have.

On the other hand, since both ends of the lamp 18 are the parts where the lamp temperature is highest,9 for example, if a so-called glove that covers the entire lamp 18 is attached to the main body of the device, the temperature inside the glove will be quite high. If heat dissipation slits 3 are provided in each of the two lamp socket mounting portions 5.

Since the heat dissipation slit 3 functions as a ventilation hole within the globe, there is also the advantage that the characteristic deterioration of the fluorescent lamp 18 due to heat can be prevented.

As explained above, in this invention, an electronic starter attached to the back side of the lamp socket is placed in a position facing the heat dissipation slit of the fixture body, which makes it possible to downsize the fixture body itself and improve the design of the lighting fixture. It has the effect of greatly expanding freedom.
