Then, the sum of the voltage drop between the transistor and the resistor in the plurality of LED units is input to the lowest voltage detection device, the smallest voltage among the LED units is detected, and the power supply unit so that this voltage becomes the target value. The output voltage is controlled.

  By having the MCU (Micro Controller Unit microcomputer) in the illumination lamp (LED bulb, LED fluorescent lamp, etc.), it is possible to cope with, adjust, and output different voltages, currents, and frequencies. For example, there are different lighting methods for fluorescent lamp fixtures that are mounted on fixtures of different types such as rapid, glow, and inverter, voltage differences, and lighting fixture manufacturers, but these different schemes can be determined and adjusted by the MCU. That is, as shown in FIG. 3B, the MPU receives the input signal, and generates and outputs an adjustment signal.

  According to the present invention, a memory function having an ID can be provided to an illumination lamp (such as an LED bulb or an LED fluorescent lamp). By providing a memory function having an ID to an illuminating lamp (such as an LED bulb or an LED fluorescent lamp) in this way, it is possible to steal appliances, manage assets, and manage replacement time.

  Also, by providing a memory function having an ID to an illuminating lamp (such as an LED bulb or an LED fluorescent lamp), individual power consumption and usage status can be managed. Therefore, it can be useful for energy management and energy management in the ESCO business.

  According to another embodiment of the present invention, it is possible to incorporate a secondary power source (battery, capacitor, capacitor, etc.) in an LED bulb or LED fluorescent lamp. Thus, when a secondary power source (battery, capacitor, capacitor, etc.) is built in the LED bulb or LED fluorescent lamp, the illuminance can be maintained for a certain period even if the power supply circuit is shut off. Therefore, it can be used as a guide light in the event of a fire or disaster.

  In the event of a fire or disaster, it is possible to notify people with hearing loss or flashing lights such as disasters, abnormal situations, visitors, calls, etc. by sensors and communication in places where it is difficult to hear sound (construction site, workplace) become.

It becomes possible to do.

  It is also possible to give the LED bulb and the LED fluorescent lamp a communication function by blinking light. Such an illuminating lamp of the present invention emits invisible light and can transmit safe and data-protected information.

  By incorporating a memory, information can be transmitted and received periodically even in places where there is no communication circuit. As a result, it is possible to install an information terminal at low cost without requiring new equipment and construction.

  In LED bulbs and LED fluorescent lamps, a Peltier element and other cooling devices are incorporated in order to enhance the heat dissipation of the appliance, and the cooling effect of the substrate and the LED is enhanced.

It has a function to memorize in advance the difference in numerical values such as the voltage and current value of each part of the resistor and parts on the circuit, and the voltage and current are automatically applied to the circuit pattern that allows voltage and current to flow only between preset points. Built-in circuit to check the above. Measurements can be made sequentially to identify faulty parts.

  The dimming function, timer function, and other switches such as blinking and MCU control do not require a special input terminal, and can be controlled by inputting a signal from the power input terminal. Since there are no input terminals, input buttons, etc., it is possible to reduce parts and prevent malfunctions due to mischief.

There were problems such as not hitting and darkness. In particular, the mounting of fluorescent lamp fixtures with the inverted Fuji type 2 lamp type has a problem that it is difficult for light to hit directly below. The connection terminal portion does not rotate, and the main body rotates and moves the irradiation portion, so that it is difficult for the light to be hard to hit. Moreover, since it can rotate arbitrarily, it becomes possible to irradiate the effect as an indirect illumination and a specific place effectively.

  The fluorescent lamp type LED has a problem that the directivity, which is a characteristic of the LED, is strong, and a part of the fluorescent lamp type LED is not exposed to light or dark depending on the installation place or the installation place. In the case of vending machines and product displays, in the case of conventional fluorescent lamps, it was possible to irradiate in the opposite direction such as the vertical direction and the horizontal direction. Irradiation in the direction of 180 degrees was difficult. Solution: By using a reflector, irradiation in the direction of 180 degrees facing each other without using a plurality of substrates is possible. In FIG. 5A, irradiation in the direction of 180 degrees facing each other is made possible by using a double-sided substrate (FIG. 5B).

  The illuminating lamp of the present invention can be applied to a fluorescent lamp type LED having a sterilizing function by mounting a UV LED (ultraviolet wavelength LED). By mounting UV LED (ultraviolet wavelength LED), it is effective for sterilization of viruses and the like. Direct viewing of UV LEDs (ultraviolet wavelength LEDs) or exposure to ultraviolet light can cause skin and eye damage. In addition, as shown in Figure ○, the LED is mounted on one side for illumination and on the other side against the UV LED (ultraviolet wavelength LED). Can be given.

  In addition, due to the characteristics of the LED, there is a problem that the directivity of light is strong and it is difficult to irradiate light in the 360 degree direction.
