Abstract
The invention relates to the technical field of lighting of light emitting diodes (LEDs) and the field of automation control and discloses an LED lamp tube with emergency dimming and lighting functions. According to the LED lamp tube, double functions are integrated, emergency lighting brightness can be adjusted, and the LED lamp tube can be matched with the same type of common LED lighting lamp with the same shape, so that the LED lamp tube has unified appearance and different functions, and is convenient and practical. During emergency lighting, the lighting brightness is reduced; and an extremely small lithium battery is arranged in the LED lamp tube, so that the LED lamp tube can be used for emergency lighting for a relatively long time.
Description
Technical field
The present invention relates to the LED lighting technical field, and automation control area.
Technical background
Under the background that Present Global energy starved worry raises once again, energy savings is the important problem that we shall face future, at lighting field, the application of LED luminous product is just attracting common people's sight, LED is as a kind of novel green light source product, must be the trend of future development, 21st century will enter the novel illumination light source epoch take LED as representative.
Summary of the invention
The present invention relates to the LED lighting technical field, and automation control area.The design of emergency lighting of LED light fixture, mainly solved on the basis of common LED lighting, increased emergent lighting dimming function, and the one or more lower and suitable brightness of illuminations of design control, guarantee the time of emergency lighting as far as possible, greatly improve the cost performance of product, and its integrated design, very easy to use, reliable, have very high using value.
The LED fluorescent tube that contains emergent lighting dimming function by the present invention's design is characterized in that: include the special lamp holder of LED fluorescent tube (1), LED fluorescent tube normal lamp holder (2), LED fluorescent tube body (3), emergency lighting control module (4), poly-lithium battery and discharge and recharge control module (5), LED built-in power (6).
The special lamp holder of described LED fluorescent tube (1) can be installed emergency lighting control module (4) in its cylinder, the tube wall top drilling is used for installing toggle switch or toggle switch.Described LED fluorescent tube normal lamp holder (2), identical with the special lamp holder of LED fluorescent tube (1) size shape, tube wall is without mounting hole site.
Described LED fluorescent tube body (3) is the utility lamp body, is comprised of aluminium type fluorescent tube body and lamp tube cover.
Described emergency lighting control module (4), be installed in the special lamp holder of LED fluorescent tube (1), consisted of by power supply control commutation circuit, PWM dim signal generative circuit, led drive circuit, transferring in the emergency lighting situation of lithium battery power supply, by 555 integrated circuits or equivalent control circuit, generate the PWM square-wave signal of a fixed frequency, fixed duty cycle, send LED to and drive chip (connecing the DIM light modulation mouth that LED drives chip), the emergency lighting brightness of LED lighting is turned down, to guarantee to obtain the longer emergency lighting time.
Described emergency lighting control module (4) connects an external control device, such as toggle switch, controls it and whether enters duty.The design's the LED fluorescent tube that contains emergent lighting dimming function is off working state when dispatching from the factory, and only just opens after installation and enters duty.

Described poly-lithium battery and discharge and recharge control module (5), can be according to shape, the space requirement of LED fluorescent tube body (3), and the requirement of lithium battery heap(ed) capacity, design its geomery, in order to it is positioned in the aluminium type fluorescent tube body of LED fluorescent tube body (3).
Described LED built-in power (6) is used in the LED fluorescent tube of directly powering with alternating current; For the LED fluorescent tube of direct current supply, do not contain LED built-in power (6) in the fluorescent tube.
Description of drawings
Accompanying drawing 1 is the structural representation of built-in power of the present invention " the LED fluorescent tube that contains emergent lighting dimming function ".
Accompanying drawing 2 is structural representations of external power supply of the present invention " the LED fluorescent tube that contains emergent lighting dimming function ".
The specific embodiment
The LED fluorescent tube that contains emergent lighting dimming function of the present invention's design includes the special lamp holder of LED fluorescent tube (1), LED fluorescent tube normal lamp holder (2), LED fluorescent tube body (3), emergency lighting control module (4), poly-lithium battery and discharges and recharges control module (5), LED built-in power (6).The core concept of its design is exactly on common LED lighting, increases emergent lighting dimming function.In the emergency lighting situation, applicable and lower brightness of illumination is provided, provide the long emergency lighting time to guarantee the built-in lithium battery of fluorescent tube.
The present invention can be fit to the LED fluorescent tube of the external AC of on-chip power, and the external external galvanic LED fluorescent tube of power supply.The external galvanic LED fluorescent tube that power supply is external, LED built-in power (6) is no longer contained in its inside.
Described emergency lighting control module (4) is installed in the special lamp holder of LED fluorescent tube (1), and connects the direct current input of LED built-in power (6) or external power supply LED fluorescent tube, and poly-lithium battery and discharge and recharge control module (5).
Described emergency lighting control module (4) has two kinds of designs to select, and a kind of mode is the emergency lighting brightness of fixing, and such as 30%, fixes by electronic circuit when designing and producing.Outside gauge tap or device only have two condition selectings, and the one, off working state, assurance LED emergency light is not worked during installing and using; The 2nd, duty, in case the externally fed disappearance, built-in lithium battery namely begins power supply, the LED emergency light is opened the brightness of setting, such as 30%.
Another kind of mode is capable of choosing multiple emergency lighting brightness, by external multidigit toggle switch or equivalent device, a plurality of state values are set, then, single-chip microcomputer is according to the state value of toggle switch and the agreement of agreement, generate corresponding PWM dim signal, control the brightness of LED emergency light emergency lighting.The state value of toggle switch is 0 o'clock, and the LED emergency light is in off working state, avoids in not lithium battery discharge between installation period.
The present invention also can be used on the various LED lightings such as LED square front lamp, LED circular lamp, and protection scope of the present invention is all classified in any equivalent concepts or change in the present invention discloses technical scope as.
