Abstract
The utility model provides a LED household lamp adapting to an environment change and possessing a practicability. The LED household lamp comprises a lampshade and a LED lamp. The LED lamp is installed in the lampshade. The LED household lamp is characterized in that the lamp also comprises an AC/DC switch power supply, a DC/DC constant current driving power supply, a power driving circuit, a photoresistor, a detection circuit and a master control circuit; the AC/DC switch power supply is connected with the LED lamp through the DC/DC constant current driving power supply; the DC/DC constant current driving power supply is connected to the master control circuit through the power driving circuit; the photoresistor is installed on the lampshade and is connected to the master control circuit through the detection circuit. The LED household lamp of the utility model controls a brightness of each lamp point according to feedback data of the light brightness detected by the photoresistor so that the light brightness of a whole room is consistent and an electric power resource is saved.
Description
Technical field
The utility model relates to a kind of LED fluorescent lamp, particularly relates to a kind of LED household lamp with practicality that conforms and change.
Background technology
According to the environmental change tunable optical, namely can adjust lamplight brightness according to the requirement of varying environment variation, thereby adjust the indoor light light and shade, set off out different indoor environment atmosphere.Incandescent lamp and Metal halogen lamp are used more extensively in the light modulation field, but the continuous popularization along with energy-saving and emission-reduction, the LED tunable optical begins to present development trend, the LED tunable optical is referred to as the intelligent series of LED together with LED infrared intelligent fluorescent tube, the control of LED acousto-optic etc., in today that the price competition of LED ordinary lamp and lantern is growing more intense, the LED intellectuality has become the developing direction of large LED Illumination Enterprise, but existing LED fluorescent lamp light modulation Shortcomings in varying environment.The invention provides a kind of LED household lamp with practicality that conforms and change, the light power of light source position can be detected, and adjust the luminous intensity of light source according to the data that detect, make the light power in whole room basically identical, the conservation of power resource.
The utility model content
The purpose of this utility model just is to provide a kind of LED fluorescent lamp that can photosensitive light modulation.
the purpose of this utility model is achieved through the following technical solutions: a kind of LED household lamp with practicality that conforms and change, comprise lampshade, the LED lamp, described LED lamp is arranged in lampshade, it is characterized in that: it also comprises the AC/DC Switching Power Supply, the DC/DC constant-current driving power supply, power driving circuit, photo resistance, testing circuit, total control circuit, described AC/DC Switching Power Supply is connected with the LED lamp by described DC/DC constant-current driving power supply, described DC/DC constant-current driving power supply is connected on described total control circuit by described power driving circuit, described photo resistance is arranged on lampshade, and be connected on described total control circuit by testing circuit.
Further, described total control circuit adopts Single-chip Controlling.
The beneficial effects of the utility model are: (1) each lamp point detects separately, unified control, and accuracy of detection is high, and utilization rate of electrical is high, is convenient to safeguard.
(2) the utility model by adopting light-sensitive element sensitization, can dim the LED fluorescent lamp when fine day, so just can be further energy-conservation.
(3) the utility model by adding the DC/DC constant-current driving power supply at the regular tap constant voltage source, can be realized the tunable optical of LED fluorescent lamp.
Description of drawings
Figure l is structural representation of the present utility model.
In accompanying drawing: l, AC/DC Switching Power Supply 2, lampshade 3, testing circuit 4, LED lamp 5, DC/DC constant-current driving power supply 6, power driving circuit 7, photo resistance 8, total control circuit.
Embodiment
as shown in Figure 1, a kind of LED household lamp with practicality that conforms and change, comprise lampshade 2, AC/DC Switching Power Supply 1, DC/DC constant-current driving power supply 5, LED lamp 4, photo resistance 7, testing circuit 3, total control circuit 8, DC/DC constant-current driving power supply 5 connects described AC/DC Switching Power Supply 1 and LED lamp 4, LED lamp 4 is arranged in lampshade 2, photo resistance 7 and testing circuit 3 all are fixed on lampshade 2, lampshade 2, LED lamp 4, photo resistance 7, testing circuit 3 forms a LED lamp point, AC/DC Switching Power Supply 1, DC/DC constant-current driving power supply 5, LED lamp 4, photo resistance 7, testing circuit 3, between total control circuit 8 by wire bond, described total control circuit 8 adopts single-chip microcomputer, a described photo resistance 7 can be controlled a plurality of LED lamps 4, the described LED household lamp with practicality that changes that conforms also comprises power driving circuit 6, these power driving circuit 6 one ends are connected in total control circuit 8, the other end is connected in described DC/DC constant-current driving power supply 5.
The utility model operation principle is as follows: LED lamp 4 adopts AC/DC Switching Power Supply 1 to drive, tunable optical DC/DC constant-current driving power supply 5 of access between AC/DC Switching Power Supply 1 and LED lamp 4, photo resistance 7 detects the brightness of light and exports a voltage to total control circuit 8 by testing circuit 3, then total control circuit 8 controls according to this magnitude of voltage the size of current that DC/DC constant-current driving power supply 5 is distributed to LED lamp 4, thereby controls the luminosity of LED lamp 4.The brightness of each lamp point is controlled according to several LED lamp points need to be arranged in the inside, room according to the feedback data of photo resistance 7 detected light luminances by total control circuit 8, so both can make the light luminance in whole room consistent, again the conservation of power resource.
It is to be noted; the utility model is not limited to above-mentioned execution mode; any simple modification, Combination application, equivalent variations and modification that any those skilled in the art do above-described embodiment in based on technical solutions of the utility model all belong in protection range of the present utility model.
