Description

Electronic Bulb Module Interface with Variety Sensor Array

The most critical sensor used in the present invention is a pyroelectric infrared sensor, and examples thereof include a quantum type using an internal photoelectric effect of a semiconductor and a thermal type using a change of a material constant as the material temperature rises.

The quantum type has a high sensitivity and excellent detection capability, but the equipment is large because it requires cooling with a coolant or an electronic refrigeration element, etc., and there is a problem in practical use because the sensitivity is dependent on infrared wavelength. On the other hand, the thermal type is disadvantageous due to its low sensitivity, but it is suitable for practical use because of its great advantage of being able to operate at room temperature.

Types of thermal type include Borometer using pyroelectric effect and electric resistance change, Thermofile by thermoelectric power, High Ray cell that optically detects thermal expansion change of gas by infrared absorption, and Electronic Tunnel Current. STM type and the like are mainly classified into a type using detection of a change in resonance frequency due to thermal expansion of a diaphragm or detection of an applied voltage to a constant current of a semiconductor pn junction diode.

Pyroelectric sensors are relatively sensitive due to their thermal characteristics and have low noise due to the occurrence of signal charges without the application of voltage from the outside. They are frequently used. In recent years, pyroelectric image sensors using infrared imaging have attracted attention.

Infrared imaging devices (Pyroelectric Image Sensors) have excellent detection performance, but they are not practically used, but Si Schottky barriers, InSb, HgCdTe, etc. As a result, a product having excellent performance in burns and the like has been developed.

In addition, ultrasonic sensors using ultrasonic waves, photodiode sensors sensitive to light signals, biosensors using the natural environment, etc. have recently developed various kinds of excellent products in various fields, such as factory automation, unmanned surveillance automation, It is showing remarkable growth in the advancement of control systems.

In general, the light bulb has been continuously developed as an excellent product over a century long since Edison's invention over a hundred years, the future trend is the use of ultra-low power bulb using a laser array.

Meanwhile, power-saving indoor light modules using pyroelectric infrared sensors have already been put into practical use and are widely used, and there are already products that can be used to control lights separately in each room.

Since the current energy-saving interior lamps are being assembled and marketed in one piece, the existing interior lamps become unnecessary and have a problem of waste of resources.

In addition, the front and rear detection system in the vehicle is mainly used in high-end passenger cars, showing a significant preventive effect in personnel accidents, etc., but because the front and rear detection system equipment itself is designed to be expensive, it is difficult to attach it to a general vehicle. It can be said that the present situation.

In addition, most other sensor devices dealing with general sensors are made of a single printed circuit board (PCB) because the sensor element and the circuit driving the same are used. Therefore, when the sensor fails, the electronic printed circuit board itself is removed. There is a problem with wasteful elements that must be changed.

Accordingly, the present invention has been made to solve this problem.

The present invention relates to a sensing device used in combination with all kinds of light bulbs, the filament emits light, while using the same principle, the inside of the cap, or the middle of the cap and the lamp egg, which is the power contact portion of the lamp egg with the filament The present invention relates to an electronic bulb module interface with a variety of sensor arrays in which a sensor circuit formed of an expanded printed circuit board (PCB) is inserted.

Sensor array that uses an array of pyroelectric infrared sensors, a type of sensor that detects the human body, a laser array with a laser diode, and many other uses By using a modular method, the present invention relates to an electronic bulb module interface in which various sensor arrays, which are in the form of an array module in the form of a conventional bulb, are selectively embedded.

Hereinafter, a configuration of an electronic bulb module in which various sensor arrays of the present invention are incorporated will be described in detail with reference to the accompanying drawings.

Figure 1 shows the actual diagram of the pyroelectric infrared sensor and the principle of the sensor. Infrared refers to electromagnetic radiation having a frequency in the electromagnetic spectrum in the range just below the red light of visible light visible to the human eye. Infrared rays are classified into four types based on the wavelength.

Near-infrared is divided into 750 ~ 1500nm, mid-infrared 1500 ~ 6000nm, far-infrared 600 ~ 40000nm, and ultra-violet infrared 40000 ~ 1mm. Infrared rays are hot rays, but they are not accurate. Infrared radiation feels hot because it converts heat into human skin, and ordinary objects emit infrared radiation in proportion to their temperature.

Infrared rays are electromagnetic waves of longer wavelengths than visible light. Usually, you may think that the wavelength is 1um or more. However, in practical use, it is not used in all wavelength ranges, and 1.5um or less and 3 ~ 5um band are widely used.

Infrared sensor refers to a sensor made to detect infrared electromagnetic waves falling in the red light range of visible light visible to the human eye.

Figure 2 shows the type of human body sensor module using a commercially available pyroelectric infrared sensor.

3 is a simple principle circuit diagram of a sensing signal amplification unit using a pyroelectric sensor, and is configured to ring a piezoelectric buzzer when a human body motion is detected.

Using a pyroelectric infrared sensor, the output is properly amplified by an op amp and again driven by a rectifier circuit to the NPN transistor. For this reason, a piezoelectric buzzer can be sounded if there is a sensor signal that drives Tr2.

However, since the sensor circuit for detecting a human body requires an amplifier gain of about 70 dB around several Hz, the output may be insufficient depending on the situation of the detecting object. For this reason, multiple stages of amplification circuits should be installed to ensure the necessary gains. In addition, since the input signal is very weak, it needs to be amplified by the optical system.

Figure 4 shows a preferred high efficiency circuit that amplifies such weak pyroelectric sensor signals with high gain.

The weak signal detected by the pyroelectric infrared sensor (RE8146) is amplified to a sufficient signal through the OP amplifier, and again generates power to drive the relay through IC2 to drive the relay (Q5A-237P). Will be done. Connect the device (buzzer or melody amplifier) necessary for relay contact S1 to M2.

By mounting the circuit connected by filament and the buzzer connected in parallel to the inside of the cap (part 11 of Fig. 5),

The buzzer may ring at the same time as the lamp is turned on.

In addition, when the current from the battery of the car reaches the tail light and is applied to the printed circuit board which is the inner 11 of the cap or the external PCB 13 through the edge 1 and the cap 2,

After generating a detection signal via a sensor attached to the PCB, optionally from a variety of sensors for the required purpose,

This weak sensor signal is amplified by the op amp or transistor,

The amplified signal may be characterized by generating a predetermined signal through a sensor signal generator designed to be selectively incorporated into the buzzer 5 or the printed circuit board 11 or 13.

In this case, a circuit may be configured by merging one or more sensors 6 and 7.

For example, while detecting the human body with a pyroelectric infrared sensor (6),

In addition, as an auxiliary means, at least one display device may be selectively attached to show a position at which the module is attached or an operation characteristic of the module.

In addition, the edge 1 portion of the sensor module selected from any one of FIGS. 5 and 6 takes the form of a semicircle.

Without taking this and without the semicircle as in halogen lamps (see JC halogen in FIG. 12), etc., the edge 1 may consist of two power connection plugs, or the lamp may be connected without other semicircular edges.

In more simple terms, the ultrasonic sensor is an acoustic energy detection element of 20kHz or more.

As this kind of sensor element, a piezoelectric element using a piezo electric direct effect has been widely used.

Ultrasound is a sound wave of about 20 kHz or more, which is so high that it is usually inaudible to the human ear. Ultrasonic waves are also sound waves, which are dense waves that propagate a medium such as space, water, and solids.

Because of this, it is possible to prevent various accidents occurring unexpectedly in the rear and prevent rear collision accidents in advance.

In addition, when manufacturing the electronic bulb module interface in which various sensor arrays are selectively integrated, various effects such as saving of resources can be expected because only the lamps need to be replaced with the interface device of the present invention instead of replacing the entire existing light device. do.
