Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a headlamp used for a bicycle.

(b) Conventional technology Conventionally, this type of headlight has been known to have a nameplate with a picture or text attached to the top of the main body to improve the exterior design. Because they are exposed to direct sunlight, they deteriorate quickly and the colors of the pictures and letters tend to fade, and the nameplates cannot be seen at night.

(c) Problems to be solved by the invention The present invention was devised in view of the above-mentioned problems, and provides a bicycle headlight with an excellent design effect that causes less deterioration of the nameplate and allows the nameplate to be seen even at night. This is a technical issue.

(d) Means for solving the problem In order to solve the above technical problem, we installed translucent light guide parts on the top surface of the main body, which consists of a rear case and a front cover, from the rear case to the front cover. At the same time, a nameplate with characters, etc. drawn on it is arranged between the light guide part and the rear case, and a part of the light from the light bulb built in the main body is guided by the light guide part and irradiated onto the nameplate.

(E) Effect Since it is configured as described above, a part of the light from the bulb passes through the front cover and is irradiated onto the light guide, is transmitted inside the light guide, is reflected on the top surface of the light guide, and is irradiated onto the name plate. .

(f) Example An example of the present invention will be described in detail below based on the drawings.

1 is the left side headlight body of a 3-light symmetrical bicycle headlamp, which includes a rear case 2 with a front opening, and a transparent body that is fixed to the rear case 2 with screws 3 and covers the front opening of the rear case 2. Inside, there is a main lighting section consisting of a main light bulb 5 and a main reflector 6 on the right side (upper side in Figure 4), and a secondary light bulb on the left side (lower side in Figure 4). 7 and a sub-reflection plate 8, and an indicator light section consisting of an indicator light bulb 9 and a prism lens 10 is provided on the left side (lower side in FIG. 4).

Reference numeral 11 denotes a light-transmitting reflector mounting body that is fitted to the opening edge of the front lid 4, and includes a main frame portion 12 into which the main reflector 6 is fitted and fixed, and a main frame portion 12 into which the sub-reflector 8 is fitted and fixed. It has a sub-frame body part 13.

14 is the left side and rear surface (fourth
A light guide portion 15 is provided that extends over a portion of the upper surface of the rear case 2 and the upper surface of the front lid 4 with a light-transmitting cover that covers the indicator light portion (lower side and right side in the figure) and accommodates the indicator light portion,
Nameplate 16 with letters, pictures, etc. drawn on the inner surface of the light guide section 15
is attached. When the cover 14 is attached to the rear case 2, the nameplate 16 is held between the light guide section 15 and the rear case 2.

17 is a small light bulb that is attached to the rear surface of the rear case 2 and stored in a space surrounded by the rear surface of the rear case 2 and the cover 14, and can be turned on by operating a manual switch provided on the handlebar of the bicycle, etc. A battery (none of which is shown) is used as a power source to turn on the light and illuminate the ring lock, etc.

In addition, the main light bulb 5, the sub light bulb 7, and the instruction light bulb 9
Like the small light bulb 17, it is connected to a manual switch installed on the handlebar of a bicycle, etc., and when the manual switch is operated, the main light bulb 5 is powered by the generator, and the auxiliary light bulb 7 is powered by the battery. The indicator light bulb 9 blinks when a manual switch is operated to indicate a left turn.

Operate the manual switch to turn on the main bulb 5 or sub bulb 7.
When the main bulb 5 or the sub bulb 7 is turned on, a part of the light from the main bulb 5 or the auxiliary bulb 7 passes through the front cover 4 and is irradiated onto the front part of the light guide section 15 as shown in FIGS. 2 and 3. The light is diffusely reflected by the light and illuminates the nameplate 16.

Similarly, when the small light bulb 17 is turned on, a portion of the light is guided by the light guide section 15 and is diffusely reflected by the upper surface of the light guide section 15 to illuminate the nameplate 16.

(g) Effects of the invention Since the nameplate is constructed as described above, the nameplate is protected by the light guide, and rain and sunlight do not directly hit the nameplate, making it possible to extend the life of the nameplate and making it possible to maintain the characters on the nameplate. It can prevent fading. Also,
Since the nameplate is illuminated by the light of the light bulb, the nameplate can be seen even at night, resulting in a great design effect.
