DE202014007437U1 - Multifunctional bicycle light with automatic and manual dimming function as well as integrated tail light and sound function - Google Patents

Abstract

Protection claim 1: automatic dimming bike lights (1) with integrated light guide (2) and light sensor (6), whereby oncoming light detected and the luminosity of the lighting (1) by the electronics (3) automatically shut down accordingly "dimmed" is. If no more oncoming light is detected, the electronics (3) regulate the brightness automatically, in the last driven light level. The "dazzling" oncoming vehicles is thus very strongly prevented. This automatic dimming can be deactivated at any time by the user by pressing a button.

Description

State of the art:

Current generations of bicycle lights rely more and more on the LED technology.

Such used high-end LEDs have the advantage of a very high luminosity with relatively low energy consumption.

A major disadvantage of these lighting devices, however, is the "glare" of oncoming persons and vehicles.

Technical task:

A bicycle light ( 1 ) to develop with different levels of luminous intensity, which by means of light guide ( 2 ) and light sensor ( 6 ) detects oncoming light (vehicles) and automatically dims the light intensity from a previously selected light level down to a predetermined "glare-free" light level.

After the oncoming light has gone out (the oncoming vehicle has passed by) the light intensity is automatically restored to the previously set light level. -> automatic dimming (protection claim 1)!

In order not to dazzle oncoming pedestrians og this process instead of automatically using fiber optics, also in addition manually, by a short finger pressure on a specially provided dimming button ( 4 ) can be performed. -> Manual dimming by means of a separate dimmer switch, (protection claim 2)!

Furthermore, the illuminated pushbuttons of the bicycle lamp by a predetermined keystroke combination can also be used as a tail light to protect the cyclist for subsequent traffic, better recognizable and thus better. Useful for helmet installation.

In this mode, the buttons "red" -> button-backlight function, (protection claim 3)

To round off the bicycle light, we additionally provide this with a sound module and can therefore also be used as a bell (signal generator). This so-called sound module is used in the electronics of the lamp. integrated. The operator has several, freely selectable tones to choose from. The operation takes place via a button on the control unit. -> sound function, (protection claim 4)

Embodiment of the invention will be explained with reference to FIGS. 01 to 06.

Technical solution:

Machine. Dimming (protection claim 1):

The bicycle light ( 1 ) with a light guide ( 2 ) and corresponding electronics ( 3 ) Mistake.

The light guide ( 2 ) receives the incoming light and passes it to a light sensor ( 6 ), which sits on an electrical board ( 3 ), continue.

This light guide ( 2 ) is installed in the housing of the bicycle lamp, that this the light directly to the sensor ( 6 ) of electronics ( 3 ) can forward.

When the electronics ( 3 ) such a light signal from the optical fiber ( 2 ), this regulates the light intensity of the lamp ( 1 ) to a lower "glare-free" strength.

As soon as the light signal has disappeared, the electronics ( 3 ) the light intensity back to the previously selected light level.

The operator of the bicycle light can choose different levels of lighting as needed. Each of these light levels is controlled by the light guide ( 2 ) and electronics ( 3 ), as described above, dimmed.

This automatic dimming can be deactivated at any time by pressing a certain key. Ie. Signal from an oncoming light is no longer processed. Bicycle light remains in the selected light level.

Manual dimming (protection claim 2):

Should be in the dark z. B. pedestrians (without light source such as flashlight etc) accommodate, the above-mentioned light sensor ( 6 ) over the light guide ( 2 ) recognize no light source of these persons and thus not dim.

Machine. Dimming is not possible in this case.

In order not to blind these people unnecessarily strong, the bicycle light ( 1 ) can also be switched manually to a predetermined, lower "glare-free" light intensity.

For this purpose, a dimming button ( 4 ) provided the lamp ( 1 ) is controlled by a short pressure immediately in this "glare-free" level.

By briefly pressing the same button ( 4 ), the electronics regulate the light intensity back to the previously selected light level.

The operator of the bicycle light ( 1 ) can select different levels of lighting as needed. Each of these light levels is controlled by the keystroke of the electronics ( 3 ), as described above, dimmed.

Button backlight function (protection claim 3):

Operation of the bicycle light ( 1 ) is by means of two side-by-side illuminated pushbuttons ( 5 ).

A certain keypress combination allows the electronics ( 3 ) the bicycle light ( 1 ) in the taillight mode mentioned here.

In this taillight mode, the two illuminated pushbuttons ( 5 ) now constantly red. By pressing this button combination again, these two permanent red illuminated buttons ( 5 ) changed in red flashing.

Pressing this key-press combination again will leave the taillight mode and the bicycle light ( 1 ) brought back to "normal mode". Keys ( 5 ) light up according to the selected setting.

Sound function (protection claim 4):

The electronic circuit ( 3 ) of the luminaire ( 1 ) with a so-called "sound module" ( 7 ) (a special IC). The operator can enter the sound mode via a preset key combination via the SW. Here he can select a certain tone from a number of given signals. In normal operation, this sound can then be triggered by a short keystroke.

Conclusion:

In the end, we have a lighting device that allows both deactivatable, automatic and manual dimming. Thus, oncoming vehicles and pedestrians are no longer exposed to a long, strong "glare".

The button-tail light function gives the cyclist additional protection. This multifunctional bicycle lighting is rounded off by the bell function, which makes it possible to attract attention at any time without having to attach additional components to the bicycle.

Claims (4)

Protection claim 1: automatic dimming bicycle lights ( 1 ) with integrated light guide ( 2 ) and light sensor ( 6 ), which detects oncoming light and the luminous intensity of the illumination ( 1 ) through the electronics ( 3 ) is automatically dimmed down accordingly. If no more oncoming light is detected, the electronics ( 3 ) the brightness automatically returns to the last driven light level. The "dazzling" oncoming vehicles is thus very strongly prevented. This automatic dimming can be deactivated at any time by the user by pressing a button. Protection Claim 2: Manual Dimming Bicycle Lights ( 1 ) with separate dimmer switch ( 4 ), by the operation of a very fast dimming is guaranteed. Current luminosity is thereby, by means of built-in electronics ( 3 ), adapted to a virtually glare-free luminosity. By pressing this dimmer button ( 4 ), the light intensity is brought back to the last selected lighting level. The "dazzling" oncoming pedestrians is thus very strongly suppressed. Protection claim 3: Button backlight function The two buttons ( 5 ) for the operation of the illumination device ( 1 ) are by a certain keyboard shortcut from the electronics ( 3 ) switched to a backlight mode. In this mode, both buttons ( 5 ) red. It can be selected by appropriate key combination whether red continuous light, red thread or red flashing are desired. Protection claim 4: sound function By integrating a sound module (IC), the bicycle light is equipped with a sound function. This allows the operator to select a sound and then make it aware of itself at any time.
