[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
A first embodiment of the present invention will be described with reference to FIG.
FIG. 1 is a cross-sectional plan view showing a configuration of a lighting device according to the embodiment of the present invention.
[0012]
In FIG. 1, reference numeral 1 denotes a light source unit including a light emitting diode 11, a fixing member 12 for fixing the light emitting diode 11, and an adjusting member 13 for adjusting the position of the light emitting diode 11 with respect to the reflecting mirror 2. The light-emitting diode 12 emits light in a direction intersecting the optical axis of the light-emitting diode 11 and is disposed only on the optical axis X of the reflecting mirror 2. A fixing member made of metal, 121 is a large-diameter mounting portion for mounting the light-emitting diode 11, 122 is a small-diameter columnar portion extending in the opposite direction to the light-emitting diode 11 following the mounting portion 121, and 13 is an axial direction. Has a predetermined thickness, and has a through hole 131 at the center, and an adjusting member made of metal into which the columnar portion 122 of the fixing member 12 is inserted into the through hole 131, 131 is a through hole, and 132 is a through hole. The bottom part 2 of the adjusting member 13 is a reflecting mirror that reflects light emitted from the light source part 1 having the light emitting diode 11, the reference numeral 21 is a neck part having a space formed inside the top part of the reflecting mirror 2, and the reference numeral 211 is the reflecting mirror 2 The bottom of the neck 21, 212 is a through hole provided in the bottom 211 of the neck 21, 3 is a base, 4 is between the outer peripheral surface of the fixing member 12 and the outer peripheral surface of the adjusting member 13 and the inner peripheral surface of the neck 21 of the reflecting mirror 2. Is a filler made of a silicone resin or an epoxy resin having a heat dissipation function, and 5 is a lead wire, and 6 is a contact in which the respective lead wires 5, 5 are connected to a spiral power supply base by soldering.
[0013]
Although not shown, the lead wire 5 protruding from the light emitting diode 11 is connected to the groove provided on the side of the mounting portion 121, the groove provided on the side of the adjustment member 13, and the through hole 212 of the bottom 211. It is pulled out to the base 3 side.
[0014]
As shown in the figure, according to the lighting device of the present embodiment, as the light emitting diode 11, a so-called side emission type light emitting diode that emits light in a direction intersecting the optical axis of the reflecting mirror 2 is used. At the same time, since it is arranged only on the optical axis X of the reflecting mirror 2, it is not necessary to use a plurality of light emitting diodes as in the conventional lighting device, and the lighting device is configured using one light emitting diode 11. Since the position adjustment with respect to the reflecting mirror 2 only needs to be performed for one light emitting diode 11, workability for position adjustment is improved.
[0015]
Further, since the adjusting member 13 has a predetermined thickness in the axial direction, the light emitting diode 11 is mounted on the mounting portion 121 of the fixing member 12, and the columnar portion 122 of the fixing member 12 penetrates through the through hole 131 of the adjusting member 13. By placing the bottom 132 of the adjusting member 13 on the bottom 211 of the neck 21 of the reflecting mirror 2, the position of the light emitting diode 11 with respect to the reflecting mirror 2 can be easily adjusted.

Since the heat is transmitted and further radiated from the neck portion 21 and the base 3, the heat of the light emitting diode 11 can be sufficiently released, so that the light emitting diode 11 can be prevented from being thermally damaged.

Other configurations correspond to the configurations of the same reference numerals shown in FIG.
[0020]
As shown in the drawing, according to the lighting device of the present embodiment, the light emitting diode 11 is mounted on the mounting portion 121 of the fixing member 12, and the screw groove 123 of the columnar portion 122 of the fixing member 12 and the adjusting member 13 are provided. By adjusting the distance between the mounting portion 121 and the adjustment member 13 by screwing the screw groove 133 of the reflection mirror 2, the bottom 132 of the adjustment member 13 is mounted on the bottom 211 of the neck 21 of the reflecting mirror 2. This makes it possible to appropriately and easily adjust the position of the light emitting diode 11 with respect to the reflecting mirror 2.
[0021]
Also, by filling the filler 4 in the space inside the neck 21 of the reflecting mirror 2, inserting the light source 1 into the neck 21 in that state, and bonding and fixing the light source 1 to the reflecting mirror 2, The same operation and effect as those of the first embodiment can be obtained.

【The invention's effect】
According to the first aspect of the present invention, in a lighting device that reflects light emitted from a light source unit having a light emitting diode by a reflecting mirror, the light emitting diode emits light in a direction intersecting the optical axis of the reflecting mirror. Since a side-emission type light emitting diode is used and the light emitting diode is arranged only on the optical axis of the reflecting mirror, it is possible to configure a lighting device using one light emitting diode. As compared with the case of using, the position adjustment with respect to the reflecting mirror only needs to be performed for one light emitting diode, and the workability for the position adjustment is improved.
[0023]
According to the invention described in claim 2, since the adjusting member has a predetermined thickness in the axial direction, the light emitting diode is mounted on the mounting portion of the fixing member, and the columnar portion of the fixing member is inserted into the through hole of the adjusting member. By penetrating and superimposing, and placing the bottom of the adjustment member on the bottom of the neck of the reflector, the position of the light emitting diode with respect to the reflector can be easily adjusted.

By adjusting the distance between the mounting portion and the adjusting member by screwing, and by mounting the bottom of the adjusting member on the bottom of the neck of the reflecting mirror, the position adjustment of the light emitting diode with respect to the reflecting mirror is appropriately and simply performed. It becomes possible to do.
[0025]
According to the invention described in claim 4, the fixing member and the adjusting member are made of metal, and the filler has a heat radiation function between the outer peripheral surface of the fixing member, the outer peripheral surface of the adjusting member, and the inner peripheral surface of the neck portion of the reflector. The light source can be bonded and fixed to the reflecting mirror, and the heat generated from the light emitting diode can be transferred to a metal fixing member and an adjusting member, and further, to a filling member having a high thermal conductivity. Since the heat is transmitted to the neck of the reflecting mirror via the agent and can be radiated to the outside from the neck, the heat of the light emitting diode can be sufficiently released, and thermal damage to the light emitting diode can be prevented.
