Escape system for a sinking car and an optoelectronic component thereof
An escape system for a sinking car and an optoelectronic component thereof are disclosed. The optoelectronic component includes a housing and an optoelectronic module. The escape system for a sinking car includes an optoelectronic component and a motherboard. A lighting unit of the escape system for a sinking car and an optoelectronic component thereof is installed on a car to emit light. After the car fell into water, by the characteristic that when light passes through a medium, the attenuation in light energy can be detected effectively because light is absorbed by that medium (such as liquid), the car sinking signal can be received and transmitted quickly, thereby actually taking the opportunities of rescue to reduce casualties.
1. An optoelectronic component comprising:
a housing, an interior of which is provided with a holding space, and a side of which is opened with a through-hole, with that two shield plates are disposed correspondingly on two sides of the through-hole, and an angle is provided between each of the shield plates and the side of the housing; and
an optoelectronic module, which is disposed inside the holding space and includes a lighting unit, a receiver, a computation unit connected electrically to the receiver, and a signal transmission unit connected electrically to the computation unit, wherein the lighting unit projects a light beam, the receiver receives the light beam projected by the lighting unit and analyzes the luminous intensity of the light beam, and the computation unit compares the luminous intensity transmitted by the receiver with a built-in luminous intensity setting; when the luminous intensity is smaller than the setting of the luminous intensity, the computation unit generating a car sinking signal, and the signal transmission unit sending out that car sinking signal through a wire communication or wirelessly, wherein the angle is between 5° and 65°, the equation that the receiver uses to analyze the luminous intensity of the light beam is

where A is the absorbance, I is the luminous intensity after light passes through a medium, I 0 is the luminous intensity before light passes through that medium, and T is the transmittance or the percentage of light transmission.
2. The optoelectronic component according to claim 1 , wherein the lighting unit is a monochrome lighting element, a monochrome lighting device, an LED or an optical fiber.
3. The optoelectronic component according to claim 1 , wherein an inner side of the through-hole is further provided with a water permeable layer.
4. The optoelectronic component according to claim 3 , wherein the water permeable layer is a layer of material containing fiber or a layer of cloth.
5. An escape system for a sinking car, bcing provided on
a car and comprising:
the optoelectronic component according to claim 1 ; and
a motherboard which is connected electrically to the optoelectronic component, wherein after receiving the car sinking signal transmitted by the signal transmission unit, the motherboard connects electrically a motor of the car to activate a car window, and connects electrically an electromagnetic switch of the car to unlock a seat belt.
6. The escape system according to claim 5 , wherein the escape system is further provided with an UPS which supplies electricity required by the escape system uninterruptedly.
7. The escape system according to claim 5 , wherein the escape system is further connected electrically to an APP inside a mobile device installed in the car or held by the driver, and after receiving the car sinking signal, the escape system turns on an automatic positioning function in the APP.
8. The escape system according to claim 7 , wherein the APP further sends out a distress text or dials a distress call through a voice assistance or an automatic dialing mechanism.
9. The escape system according to claim 5 , wherein the motherboard is further connected electrically to a horn of the car and turns on the horn to sound after receiving the car sinking signal.
10. The escape system according to claim 5 , wherein the motherboard is provided with a control unit.
11. The escape system according to claim 10 , wherein the control unit is connected electrically to a motor, plural car lamps and a horn.
