Abstract
A fog light device has a base casing, a lampholder, a transparent lampshade, a photoconduction plate, an outer casing, a main bulb, and at least an auxiliary bulb. The base casing has a hollow interior to receive at least a positioning seat. The auxiliary bulb is connected to the positioning seat. The main bulb is inserted in the center through hole of the lampholder. The transparent lampshade is inserted in the annular recess of the lampholder. The photoconduction plate is inserted in the annular channel of the lampholder. The photoconduction plate has a first taper end and a second taper end to receive a light emitted by the auxiliary bulb.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a fog light device. More particularly, the present invention relates to a fog light device which is disposed on a vehicle.
Referring to
FIG. 5
, a conventional fog light device has a rear lampholder
10
, a front lampshade
20
engaging with the rear lampholder
10
, the rear lampholder
10
having an inner reflection mirror
101
, and a bulb
30
inserted in a center of the rear lampholder
10
. However, the conventional fog light device has a single bulb to perform a single illuminating function only.
Another conventional fog light device has a rear lampholder, a front lampshade engaging with the rear lampholder, the rear lampholder having an inner reflection mirror, a main bulb inserted in a center of the rear lampholder, and an auxiliary bulb inserted in the rear lampholder. However, the main bulb and the auxiliary bulb perform two illuminating functions only. Since the auxiliary bulb is inserted in the rear lampholder, a hole should be formed on the rear lampholder in order to receive the auxiliary bulb. Therefore, the inner reflection mirror cannot focus light effectively. Since the auxiliary bulb is inserted in the rear lampholder, an aesthetic feeling of the auxiliary bulb is ugly.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a fog light device which has a main bulb and an auxiliary bulb to perform three illuminating functions. When the main bulb emits light, an inner reflection mirror of a lampholder focuses the light effectively. When the auxiliary bulb emits light, the light enters a photoconduction plate through a first taper end and a second taper end of the photoconduction plate. When the main bulb and the auxiliary bulb emit light, two kinds of light are produced.
Another object of the present invention is to provide a fog light device which has a colorful photoconduction plate to produce a colorful light.

engages with the connecting seats
13
.
The lampholder
2
has a bowl-shaped shell
20
, an inner interior of the bowl-shaped shell
20
forming an inner reflection mirror
21
, a center through hole
210
formed on the bowl-shaped shell
20
to receive the main bulb
22
, an annular channel
23
formed on a front edge of the lampholder
2
, an annular recess
233
adjacent to the annular channel
23
, a plurality of arc-shaped slots
232
formed on the annular channel
23
, and a plurality of oblong through holes
231
formed on a bottom of the annular channel
23
.
The main bulb
22
is inserted in the center through hole
210
of the lampholder
2
.
The transparent lampshade
3
is inserted in the annular recess
233
of the lampholder
2
.
The photoconduction plate
4
is inserted in the annular channel
23
of the lampholder
2
.
The photoconduction plate
4
is made of a transparent material such as glass or a polycarbonate (PC).
The photoconduction plate
4
has a convex face
41
formed on a front face of the photoconduction plate
4
, an outer flange
42
formed on an outer edge of the convex face
41
, an inner flange
43
formed on an inner edge of the convex face
41
, a first taper end
44
, a second taper end
45
, and a serrated face
46
formed on a rear face of the photoconduction plate
4
.
The outer casing
5
has a C-shaped slot

The present invention has the following advantages.
1. The present invention provides the fog light device which has a main bulb and an auxiliary bulb to perform three illuminating functions. When the main bulb emits light, the inner reflection mirror of the lampholder focuses the light effectively. When the auxiliary bulb emits light, the light enters the photoconduction plate through the first taper end and the second taper end of the photoconduction plate. When the main bulb and the auxiliary bulb emit light, two kinds of light are produced.
2. The auxiliary bulb is made of a tungsten or a light-emitting diode (LED).
3. Since the auxiliary bulb is disposed between the base casing and the lampholder and the photoconduction plate photoconducts the light emitted by the auxiliary bulb, the light focus function of the inner reflection mirror will not be worsened.
4. The auxiliary bulb is disposed between the base casing and the lampholder, so an aesthetic feeling of the fog light device is beautiful.
5. A color of the auxiliary bulb can be varied. A color of the photoconduction plate can be varied also.
The invention is not limited to the above embodiment but various modification thereof may be made. Further, various changes in form and detail may be made without departing from the scope of the invention.
