Description
Technical field
The utility model relates to a kind of lighting device with an automatic light meter.
Background technology
In some office spaces and office building, often see no matter environmental light brightness how, by day, always all open illuminating lamp night, become " altar lamp " of full power, this has wasted the light source of natural lighting on daytime widely, has also greatly consumed valuable electric power resource.What general office building office lighting major part adopted is single T8 or T5 Grille lamp, has one drag two, to drag fourth class specification, adopts symmetrical expression or asymmetric layout according to the size of environment and the shape and the lighting requirement in space.Such layout generally can not taken into account the inhomogeneities of natural lighting and space illumination.In fact, the natural lighting meeting is all changing all the time along with the different of weather, season and division of day and night, consider from the angle of more energy-conservation more environmental protection, we can make fully in the zone of daylighting abundance and reduce lighting power, lighting power is improved in zone in the daylighting deficiency, just according to the strong and weak luminous flux of adjusting light fixture automatically of surrounding environment illumination.
Because the gas discharge fluorescent lamp of T8 or T5 is because the principle of luminosity inconvenience of itself realizes light modulation, so in the place of all adopting T8 or T5 gas discharge fluorescent lamp, can not realize regulating the brightness of illumination requirement according to environmental change at present.But led light source principle and technical be to realize linearity light adjusting, if adopt photosensitive control light regulating technology, just can reach the requirement of the permanent illumination of working environment.
Summary of the invention
The utility model purpose is: a kind of lighting device with an automatic light meter is provided, makes working environment illumination remain in certain claimed range, both saved the energy, improved the comfort level of working environment again.
The technical solution of the utility model is: a kind of lighting device with an automatic light meter, comprise LED fluorescent lamp and LED fluorescent lamp driver module, described lighting device also comprises light-sensitive element and PWM (impulse modulation) dim signal generator, described LED fluorescent lamp driver module is the impulse modulation driver module, and described PWM dim signal generator is exported the pulse input end of corresponding pulse signal at least one impulse modulation driver module according to the signal of light-sensitive element input.Light-sensitive element is responded to surround lighting, optical signal is changed into the corresponding signal of telecommunication output to PWM dim signal generator, PWM dim signal generator produces corresponding pulse signal to the impulse modulation driver module according to the signal of telecommunication of input, and then the driving LED fluorescent lamp is luminous.When light-sensitive element detects environmental light brightness when higher, the duty time of the pulse signal that PWM dim signal generator sends is long, and the power that the LED fluorescent lamp consumes is little, a little less than the luminous brightness; Otherwise when environmental light brightness was low, the duty time of the pulse signal that PWM dim signal generator sends was just short, and it is big that the power that the LED fluorescent lamp consumes becomes, even total power output, and luminosity increases.
Further, in above-mentioned lighting device with an automatic light meter, described PWM dim signal generator exports pulse signal to the pulse input end of a plurality of impulse modulation driver modules.The signal that makes a light-sensitive element and PWM dim signal generator produce can be used for controlling a plurality of LED fluorescent lamps.
Further, in above-mentioned lighting device with an automatic light meter, described impulse modulation driver module comprise AC power is converted into the AC/DC constant voltage Switching Power Supply of dc source and be connected AC/DC constant voltage Switching Power Supply and the LED fluorescent lamp between tunable optical DC/DC constant-current driving power supply.
Further, in above-mentioned lighting device with an automatic light meter, described lighting device also comprises common fluorescent lamp lighting equipment.Can change the LED fluorescent lamp of adjusting brightness automatically according to ambient brightness and combine, form two illuminators of controlling with the common fluorescent lamp that is difficult to adjust brightness.Higher in environmental light brightness, when common fluorescent lamp work brightness is higher, allow LED fluorescent lamp with an automatic light meter replenish luminous or by (treating that the LED fluorescent lamp when truly place of gas is discharged fluorescent lamp fully, can all adopt the LED fluorescent lamp).
Further, in above-mentioned lighting device with an automatic light meter, described lighting device is the grid lamp, and described common fluorescent lamp lighting equipment and LED fluorescent lamp coexist on the grid lamp.
The utility model has the advantages that:
1. the utility model maximally utilises natural lighting, has reduced the power output of lighting device in the working environment kept burning day and night, energy-conserving and environment-protective.
2. the utility model LED fluorescent lamp is controlled by automatic photosensitive, need not manual adjustment.
3. the utility model makes the space illumination of working environment more even, reaches the requirement of permanent illumination, has improved the comfort level of working environment.
4. the utility model can realize that LED fluorescent lamp with an automatic light meter combines the two control of formation illuminators with the common fluorescent lamp that is difficult to light modulation, the LED fluorescent lamp is used as the additional light source of common fluorescent lamp, relaxed the heat dissipation problem in the use of LED fluorescent lamp to a certain extent.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the circuit structure block diagram of the utility model specific embodiment.
Wherein: the 1LED fluorescent lamp; The 2LED fluorescent lamp driver module; 21AC/DC constant voltage Switching Power Supply; 22 tunable optical DC/DC constant-current driving power supplies; 3 light-sensitive elements; 4PWM dim signal generator.
