Abstract
The utility model relates to a portable emergency lamp. The portable emergency lamp comprises: a power source circuit which is used for converting the voltage of AC to the voltage that is fitted to be supplied in functional circuits of each part inside the emergency lamp; a main control circuit which is electrically connection with a constant current driving circuit and is used for flicker control and light-adjusting control of an LED light source; the constant current driving circuit of which the output end is connected with the LED light source, and the constant current driving circuit being controlled by the main control circuit to adjust the brightness of the LED light source; and the LED light source which is composed of LED lights with a variety of colors. In the power source circuit, a lithium battery is adopted as a backup power source. The emergency lamp further comprises an alarm circuit used for indicating electricity shortage in the power source. The portable emergency lamp is provided with the constant current driving circuit which is controlled by the main control circuit and is capable of realizing light adjustment, which can effectively save electric energy; according to the portable emergency lamp, the LED lights with a variety of colors are adopted as light sources which are controlled by the main control circuit such that the LED lights can flicker respectively and are applicable to a variety of environmental needs, enabling diverse functions of the emergency lamp.
Description
Technical field
The utility model relates to the emergency light technical field, specifically is meant a kind of portable emergency lamp.
Background technology
Emergency light is widely used in various occasions, when the normal illumination power supply breaks down, can throw light on effectively and shows fire escape, can be described as the indispensable configuration of various building constructions.Emergency light can be classified by operating state and function.Generally can be divided into 3 types by operating state: 1. continuous schedule emergency light, this lamp can continue to provide illumination no matter the normal illumination power supply has not fault.2. non-continuous schedule emergency light, this lamp have only just provides illumination when the normal illumination power supply breaks down.3. compound emergency light is equipped with two above light sources in this emergence lighting lamp, have at least one illumination can be provided when the normal illumination power supply breaks down.But all there is function singleness in the emergence lighting lamp of usefulness in the market, goes up uncontrollable problem between in use.
The utility model content
To the problems referred to above, the utility model provides the portable emergency lamp of a kind of tunable optical, diverse in function.
The technical scheme of the utility model is following: a kind of portable emergency lamp, it is characterized in that, and comprising:
Power circuit converts electric main into suitable voltage and supplies with each several part functional circuit in the emergency light;
Governor circuit is connected with constant-current drive circuit, is used for the flicker control and the brightness adjustment control of led light source;
Constant-current drive circuit, its output connects led light source, receives governor circuit control that led light source is carried out brightness regulation;
Led light source, said led light source is made up of multiple color LED lamp.
Preferably, adopting lithium battery in the said power circuit is stand-by power supply.
Preferably, said power circuit comprises the AC/DC change-over circuit, the battery protecting circuit that is connected with the AC/DC change-over circuit.
Preferably, said emergency light also comprises the warning circuit that is used to indicate the electric quantity of power supply deficiency, and said warning circuit is connected with governor circuit.
Compared with prior art, the beneficial effect of the utility model is:
(1) said portable emergency lamp is provided with constant-current drive circuit, and it receives governor circuit control can realize dimming function, effectively saves energy;
(2) adopt multiple color LED lamp as light source, can glimmer respectively by governor circuit control and be suitable for multiple environment needs, enrich the emergency light function;
(3) adopt lithium battery as stand-by power supply, civil power can be supplied power after breaking off for more time, for said emergency light multifunction provides necessary basis, and is furnished with battery protecting circuit, improves emergency light power supply stability;
(4) be provided with the not enough warning circuit of electric weight, design hommization more.
Description of drawings
The said portable emergency lamp theory of constitution of Fig. 1 schematic block diagram.
Embodiment
Below will combine accompanying drawing and embodiment that the utility model is explained in further detail for the ease of it will be appreciated by those skilled in the art that.
Like Fig. 1; The portable emergency lamp that the utility model disclosed comprises governor circuit and constant-current drive circuit, warning circuit, power circuit and led light source; Warning circuit all is connected with governor circuit with constant-current drive circuit and controlled by governor circuit; Constant-current drive circuit also is connected with power circuit, and output connects led light source.Wherein, power circuit is used for converting electric main into suitable direct voltage and supplies with each several part functional circuit in the emergency light, like governor circuit, constant-current drive circuit etc.Power circuit specifically comprises the AC/DC change-over circuit, the battery protecting circuit and the lithium battery that are connected with the AC/DC change-over circuit.Led light source is made up of multiple color LED lamp.Governor circuit is the important component part of said emergency light, realizes the brightness regulation and flicker control of led light source.
At ordinary times, said emergency light is through connecting civil power, and civil power is a lithium cell charging through AC/DC change-over circuit conversion back, also directly is the power supply of emergency light internal circuit simultaneously.After municipal power failure or the outage of other situation, directly be the emergency light power supply by lithium battery, supply people to throw light on required.This emergency light is portable, and the occasion that portability to open air needs is used, and according to the illumination needs, the brightness of scalable led light source obtaining illumination for more time or bigger brightness, and can be controlled versicolor LED lamp respectively and glimmers by different laws.This color lamp flashing function is used very convenient, during like trip, in the situation that road is got on the car and occurred casting anchor, can regard warning lamp usefulness, and perhaps open-air the camping also can be used as warning lamp.
The foregoing description is the preferred version that the utility model is realized; And indefiniteness is exhaustive; The utility model can also have other variations under same idea; Need to prove that do not breaking away under the utility model design prerequisite, any conspicuous replacement and minor variations are all within the protection range of the utility model.
