According to this configuration, since light is emitted from the plurality of LED lamps 1, uniform brightness is obtained over a wide viewing angle, and visibility is improved. The number of the LED lamps is four, and two LED lamps may be arranged in two rows as one row. In this configuration, the plurality of LED lamps can be compactly supported by the lamp socket, the light diffusion efficiency is improved, and the visibility is further improved.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a position lamp installed separately from a main head bulb in a vehicle headlamp.

[0002]

[Prior art]

 This type of position lamp illuminates a small amount of light in the headlamp when the headlamp lighting is small, and plays a role as a vehicle sidelight, a small lamp, and the like. Conventionally, incandescent light bulbs have been mainly used as position lamps. Recently, however, the need for more vivid light and the development of LEDs that emit white light have led to the use of LED lamps as position lamps. As a result, the products used have become popular.

[0003]

[Problems to be solved by the invention]

 However, since a general-purpose standard LED lamp has a structure in which the light-emitting portion is sealed with a resin having a shell-shaped outer shape, when such an LED lamp is used as a position lamp, There is a problem that uniform luminance cannot be obtained over a wide viewing angle and visibility is poor.

An object of the present invention is to solve such a problem and to provide a position lamp using an LED lamp capable of obtaining high visibility over a wide viewing angle.

[0005]

[Means for Solving the Problems]

 The position lamp of the present invention is a position lamp using an LED lamp as a light source, and is characterized in that a plurality of LED lamps are supported by a lamp socket so that their light emitting portions are dispersed. According to this configuration, since light is emitted from the plurality of LED lamps, uniform brightness is obtained over a wide viewing angle, and visibility is improved.

In the position lamp, the number of the LED lamps is four, and two of the LED lamps may be arranged in two rows as one row. In this configuration, the plurality of LED lamps can be compactly supported by the lamp socket, the light diffusion efficiency is improved, and the visibility is further improved.

[0007]

[Embodiment of the invention]

 One embodiment of the present invention will be described with reference to FIGS. FIG. 1A is a front view showing a schematic configuration of the position lamp according to this embodiment. This position lamp uses the LED lamp 1 as a light source, and a plurality of LED lamps 1 are dispersedly supported by the lamp socket 2 and supported by the lamp socket 2. In this embodiment, the number of LED lamps 1 is four.

The LED lamp 1 is a transparent acrylic in which a light emitting portion of an LED (Light Emitting Diodes) having two lead wires 4 and 5 on an anode side and a cathode side is formed into a shell-like outer shape. It is sealed with a resin 6 or the like. Each LED lamp 1 is electrically connected in parallel. That is, the anode lead 4 of each LED lamp 1 is connected to one, and the cathode lead 5 is also connected to one. In some cases, a current limiting resistor or a constant current diode is interposed in one of the lead wires 4 and 5, but is omitted in this embodiment.

The lamp socket 2 is made of an electrical insulating material such as a resin. As shown in FIGS. 2 and 3, one end of the lamp socket 2 is a cylindrical portion 2a and the other end is a plate-like portion 2b. From the bottom surface of the LED lamp 1 to the end surface of the plate-like portion 2b, two insertion holes 7, 7 through which lead wires 4, 5 common to each LED lamp 1 are inserted are formed. By inserting lead wires 4 and 5 into these insertion holes 7, each LED lamp 1 has a lamp socket 2 so that a light emitting portion sealed with transparent acrylic resin 6 projects from the cylindrical portion 2 a. Supported by Here, as shown in a plan view in FIG. 1B, the four LED lamps 1 are arranged in two rows with two lamps as one row.

In this position lamp, as described above, each LED lamp 1 is supported by the lamp socket 2 such that the sealing portions made of the transparent acrylic resin 6 which are the light emitting portions of the four LED lamps 1 are dispersed. As a result, light is emitted from each LED lamp 1, so that uniform brightness is obtained over a wide viewing angle, and visibility is improved.

In particular, in this embodiment, since two LED lamps 1 are arranged in two rows as one row, the LED lamp 1 can be compactly supported by the lamp socket 2 and the light of the light can be transmitted. The diffusion efficiency is further improved.

[0012]

[Effect of the invention]

 The position lamp of the present invention uses an LED lamp as a light source. Since a plurality of LED lamps are supported by a lamp socket so that their light-emitting portions are arranged in a dispersed manner, uniform brightness is obtained over a wide viewing angle. And visibility is improved. In this configuration, when four LED lamps are provided and two are arranged in one row in two rows, a plurality of LED lamps can be compactly supported by the lamp socket, and the light diffusion efficiency can be improved. And visibility is further improved.
