Detailed Description of the Invention (Industrial Application Field) This invention relates to a safety lamp for automobiles, and in particular, to a safety lamp installed in the rear window of an automobile, with a height that matches the eye position of the driver of a following vehicle. installed in the position
This relates to an automobile safety lamp that lights up when braking to alert following vehicles.

(Conventional technology) A system that lights up when the driver operates the brakes! The I+ furnace is
The general structure is that they are attached to the left and right sides of the rear of a car.

(Problem to be solved by the invention) Until now, automobiles have used brake lights to indicate to following vehicles that the brakes have been applied, but the brakes installed at the rear of the automobile are located at Because it is located relatively low, it is much lower than the eye level of the driver of the car behind, making it difficult to see the brake lights of the vehicle ahead, which can cause a rear-end collision if the driver misses the brake lights that are on. The problem was that there was a risk of

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an automobile safety lamp that can be easily installed at the rear of an automobile. The above-mentioned problem is solved by adopting a lamp housing having a dual structure of a lamp housing and an inner housing, and allowing the lamp housed in the inner housing to be freely oriented in any direction.

It is rotatably abutted on the side inner surface 39 of o.

As shown in FIGS. 1 and 7, the outer housing 20
A projecting portion 28 projecting outward is formed at the center of the outside, and heat dissipation ports 48, 50 are formed on both sides of the projecting portion 28. These heat radiation ports 48 and 50 are used for heat radiation τ! of the inner housing 24. It is staggered with respect to 2.

As shown in FIG. 4, the edge frame 22 is provided with an adhesive layer 46, which faces outward. The leg 38 of the adjustment knob 30 fits into the hole 60t on the side of the inner housing.
, :IN, the inner housing is provided with a bracket that supports the reflector of the lamp.

As shown in FIG. 5, the inner housing 24 includes
There are radiating blades 42.44h bows Qk for radiating heat from the light source. The outer housing 20, central portion 2ε3, 48.50 t (-1 portion) is shown in FIG.

As shown in FIG. 8, the in-no-housing 24 includes:
Cutouts 54 and 56 for supporting the fouling plate are recessed. The heat dissipation member 42 is illustrated in FIGS. 9 and 20.

FIG. 21 shows a side view of the inner housing 24.
A circular bead 40 is recessed in the side surface, and this bead engages with the foot 38 of the adjustment knob 30.
A protrusion 43 and a W1 portion 41 are provided.

10 and 11 show the outer housing 20, the intermediate portion 28, and the heat dissipation ports 48 and 50.
8.50 is that the positions of the heat dissipation blades 42 and 44 of the inner housing 24 described in 1) are shifted so that the light from the light source does not enter the inside of the vehicle. Also,
The outer housing 20 is provided with a recess 23 into which the frame 22 is snap-fitted, and a hole 27 through which a lead wire to the light source is passed.

FIG. 18 shows the annular bead 33 and shoulder 35.

17 and 19 show a protective grid installed on the opening surface of the outer housing 20, and this grid
It consists of a frame 43 and a grid section 41 (a plurality of wires stretched horizontally), and is arranged between the frame 22 and the outer housing 20, as shown in FIG.

Various lighting circuits can be employed to light the lamp 60. In particular, when the environmental temperature is up to 15 degrees Celsius (approximately 167 degrees Fahrenheit),
It is preferable that the light be turned on at a temperature of at least -31°C (approximately -25°).

FIG. 22 shows an example of a lighting circuit, in which when terminals 66 and 68 are powered (normally 12V), lamp 60 is lit via terminal 64.

Even if no current flows through either terminal 66 or terminal 68, the lamp will not go out. When both terminals are not energized, the lamp 60 is turned off. - If the lamp goes out, the lamp will not light up even if either of the terminals is energized.

An SCR (Silicon Controlled Rectifier) 70 is used as a switch in the lamp's energizing circuit.

The large current diodes 72 and 74 constitute an OR gate,
A voltage is applied to the SCR and its trigger circuit. This trigger circuit consists of a resistor 76.82, a capacitor 78 and a (JJT11 1P circuit transistor) 80
It is made up of.

When current (voltage 12 volts) is applied to both terminals 66.68, charging of capacitor 78 begins and diode 82.84 becomes reverse biased. Capacitor 78 is charged through resistor 76 until it reaches the peak voltage vpc of UJT 80, and then UJT 80 charges capacitor 78 through resistor 82 to the gate of SCR 70. As a result, the 5CR70 is triggered from 1 to energized, and the lamp 60 lights up. Once the SCR is turned on, the voltage across the 5CR70 drops to about 1 volt, disabling the trigger circuit.

Even if one of the terminals 6G and 68 is de-energized, the diode 72 and the +1 diode door 4 continue to energize the 5CIt 70 and the lamp 60.
In short, only if both terminals are not energized, 5C
No current is applied to R70 and the lamp 60, and the lamp 60 goes out.

Diodes 82.84 and 1irj terminus 66.
When either one of 68 is energized, it acts as an AND gate, and capacitor 78 is not charged and 5C1
70 does not trigger.

In this state, even if one of the terminals 66, 68 is energized, the other terminal is off, so the input of the off-side terminal is connected to the resistor 8.
4 or pulled down by resistor 86 and 5CR70 does not trigger.

When such a circuit is installed in an automobile, even if one of the dynamic flame and direction indicator lights is disconnected, the lamp lighting circuit will operate due to the action of the pull-down resistors 84 and 86. Also, the circuit configuration is such that it does not operate depending only on the direction indicator light.

The lighting circuit described above operates even under severe temperature conditions, for example, within the temperature range C from -32°C to 74°C.
b He Xiu operates without failure.

In addition to the 12V that is generally used for automatic small appliances, the power used in the first floor ranges from 9V to 16V.

(Efficacy of the Invention! According to this invention, a lamp for displaying player operation is built into the inner housing 17, and the inner housing is surrounded by an outer housing so that the inclination angle of the inner housing can be adjusted. This system is designed to ensure the visibility of following vehicles, so even if you overlook the brake lights installed in the automatic system, you can still see the safety lamps lit. It is possible to prevent a follow-up attack due to an oversight.
