A voltage is applied to the lamp and the lamp is simultaneously lit. Further, even in the case of the auxiliary brake light device including the control unit, the plurality of LEDs are all blinked at regular time intervals. However, such a conventional auxiliary brake lamp lacks uniqueness and appeal. Further, when purchasing products of the same type, the lighting type is always the same, and the lighting pattern cannot be arbitrarily changed.

A lighting change mode in which a plurality of types of lighting patterns for designating the number and position of light emitting elements to be simultaneously turned on among the plurality of light emitting elements are combined to change the lighting pattern sequentially and repeatedly. A memory unit in which various types are set and stored in predetermined storage areas,
A changeover switch for selectively designating any one of the various types of lighting change modes for the memory unit, and a sequence for changing a repeating pattern of the lighting change modes selectively designated by the changeover switch. A clock generator for generating a clock, an adjuster for arbitrarily changing and setting the frequency of the clock generator, an address generator for counting clocks from the clock generator and sequentially providing addresses to the memory unit. According to the lighting pattern read from the memory unit according to an address command from the address creating unit, power is supplied to the memory unit, the clock generating unit, and the address creating unit in association with the brake operation of the automobile. A driving unit for lighting the plurality of light emitting elements in the selected lighting change mode. . As described above, the present invention does not use a microcomputer, and also has a changeover switch capable of selectively designating a lighting change mode and a variable resistor (regulator) capable of arbitrarily changing a changing speed of a lighting pattern. ) And a programmable light emission blinking change are configured.

 Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a vehicle auxiliary brake light device of the present invention. FIG. 2 is an explanatory diagram showing an example of change in lighting in the case of eight light emitting elements (for example, light emitting diodes: LEDs) arranged linearly. (A) to (G) show seven types of lighting change modes. Further, each row shows a lighting pattern, a blank circle indicates lighting and a shaded circle indicates extinguishment. The arrow indicates the change in time.

 The operation will be described below with reference to the drawings.

When the vehicle driver steps on the brake (brakes), the brake switch 9 becomes conductive, and the battery
Power is supplied from 10 to the power supply section 2 of the control unit 1, and the control unit 1 becomes operable. Illustration of power supply wiring to each circuit unit is omitted.

11 is a plurality of light emitting elements (for example, LEDs) arranged in a line
It is a light emitting element array consisting of, and is installed in the rear part of an automobile so that it can be seen from the following vehicle.

Reference numeral 4 denotes a memory unit composed of a ROM or the like, which is a memory for storing lighting pattern data for designating the number and positions of the lighting elements of the light emitting element array 11 at each address. For example, the address in the memory unit 4 is divided into 256 addresses, and the lighting change mode is assigned to each of the addresses.
That is, FIGS. 2A to 2G show seven types of lighting change modes. In the lighting change mode of FIG. 2 (A), "light" is set to "1" and "not light" is set to "0".
Then, store "00011000" in the first address,
"00100100" is stored in the next address, and the lighting pattern data is stored in each of the four addresses up to "10000001" to light the elements at both ends, and the lighting pattern is changed sequentially. The above four pieces of change data are repeatedly stored in the address. FIG. 2 (B)-
The same applies to (G).

Reference numeral 8 denotes a changeover switch, which is composed of a plurality of switches for selectively switching among a plurality of types of lighting change modes stored in the memory unit 5, and selects one of a plurality of types of lighting change modes or a plurality of lighting change modes. Can be selected in combination.

An address generator 3 counts the output of the clock generator 6 and sequentially supplies addresses to the memory 4. This address command is sequentially output at the speed of the clock from the clock generator 6, and specifies the changing speed of the lighting pattern.

Reference numeral 5 denotes a drive unit, which sequentially supplies a current to predetermined elements of the light emitting element array to emit light (lights) in accordance with the lighting pattern data read from the memory unit 4.

Reference numeral 7 is an adjuster composed of a variable resistor or the like for changing the frequency of the clock generator 6, and by changing the resistance value arbitrarily, the changing speed of the lighting pattern, in other words, the switching time of the lighting pattern. You can change the interval. This frequency change can be set arbitrarily within the range of several Hz to several kHz.

When a 32 Kbyte ROM is used as the memory unit 4, there are 3276 7! × 256 kinds of combinations of changes in the light emission of the light emitting element array 11, and it can be considered that the combinations are practically endless. Using the same ROM, there are 128 types of combinations that can be selected by the changeover switch only.

Further, it goes without saying that the number of elements of the light emitting element array 11 can be arbitrarily determined, and the elements can be arranged in a desired arrangement pattern such as a linear arrangement, a planar arrangement, or a distributed arrangement. Absent.

(Effect of the Invention) As described above, according to the present invention, the light emission changes of a plurality of LEDs can be arbitrarily set, so that the following effects can be obtained.

(1) Improving the appeal to the following vehicle during brake operation.

(2) Individualization can be achieved in the same product.

(3) Improved fashionability as an accessory product for automobiles.

(4) Since the light emission change pattern can be changed to a pattern other than the front lighting, the current consumption is smaller than that of the conventional one.

(5) The lighting reaction time of the LED is faster than that of the light bulb of the main braking light, and since the lighting pattern can be changed, the safety for the following vehicles is improved.
