[background technology]
Existing LED lamp is generally fixing power and brightness, can not adjust according to the power of surround lighting the luminosity of self, even in the time that surround lighting is very bright, also full power operation, causes the waste of the energy.Due in recent years, the attention of people to energy-conserving product, also there is having easily the LED lamp of certain energy-saving effect in market, it is that an optical sensor is installed in lamp mostly, for controlling the opening and closing of lamp: in the time that environment reaches certain brightness, lamp closes, lower than time lamp entirely bright, solved to a certain extent the problem of energy waste, but the mode of this single solution for diverse problems, light intensity is floated excessive, be obviously not suitable for being used in the occasion higher to illumination requirement.
[utility model content]
The utility model provides a kind of permanent illumination light sensation automatically to control LED lamp, and it is also applicable to the place higher to illumination requirement in energy-conservation.
The technical solution of the utility model is as follows:
A kind of permanent illumination light sensation is controlled LED lamp automatically, comprise MCU and sensor cluster, this sensor cluster is arranged on a place of LED lamp body light-emitting area, and this sensor cluster mainly comprises visual photometric brightness sensor, described visible light sensor is connected with described MCU, for it provides illumination parameter; Described MCU is connected with the power supply unit of described LED lamp, and it exports corresponding control signal according to the illumination parameter that receives to described power supply unit, with control described power supply unit unlatching, close or electric current output size.
The beneficial effects of the utility model are:
In MCU, set an illumination fiducial value, visible light sensor gathers the brightness value of light fixture below shadow surface and transfers in MCU, MCU is by the brightness value receiving and the comparison of illumination fiducial value, export corresponding control signal according to result relatively to the power supply unit of LED lamp, with control described power supply unit unlatching, close or electric current output size, for example: in the time that deviation is greater than 10%, increase or reduce the luminosity of LED, ensure surround lighting that visible light sensor detects illumination fiducial value ± 10% scope in; When be greater than illumination fiducial value 110% time, LED lamp is closed.
Known, adopt LED lamp of the present utility model, can be according to the power of surround lighting, regulate luminosity, ensure that it irradiates below and maintains in constant illumination range, is applicable to the place higher to illumination requirement, and effectively improved the fractional energy savings of LED lamp, and reduce optical attenuation, extend LED lamp life.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is sensor cluster schematic diagram of the present utility model;
Fig. 3 is program circuit reference diagram.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage more clear, be described in further detail below in conjunction with drawings and embodiments.It should be noted that, the present embodiment is that the LED Panel light in LED lamp is introduced, but do not represent that the utility model only only limits to LED Panel light, the utility model can also be LED Down lamp, lifting LED office lamp, LED Grille lamp etc., but identical owing to realizing principle, all can, with reference to LED Panel light, therefore not repeat one by one.
As shown in Figure 1, 2, a kind of permanent illumination light sensation is controlled LED Panel light automatically, comprise MCU and sensor cluster 2, at one jiao of LED lamp body 1 light-emitting area, open one with sensor cluster 2 consistent size mouth, sensor cluster 2 is fixed on the diffuser plate of LED lamp body 1 light-emitting area, sensor cluster 2 comprises visual photometric brightness sensor 2c, visible light sensor 2c aims at the shadow surface of light fixture or surveys light fixture the reverberation that irradiates below, has ensured the accuracy of illumination control; Wherein, visible light sensor 2c is used for gathering the illumination parameter of ambient light, and is connected with MCU, and the illumination parameter collecting is transferred to MCU; MCU is connected with the power supply unit of LED Panel light, and it exports corresponding control signal according to the illumination parameter that receives to power supply unit, with control described power supply unit unlatching, close or electric current output size.Power supply unit parts can adopt tunable optical driving power, and MCU can adopt the brightness of PWM mode control LED, or the drive current of reduction LED is controlled LED brightness.
In MCU, set an illumination fiducial value, visible light sensor 2c gathers the brightness value of ambient light and transfers in MCU, MCU is by the brightness value receiving and the comparison of illumination fiducial value, export corresponding control signal according to result relatively to the power supply unit of LED lamp, with control described power supply unit unlatching, close or electric current output size, specifically can be as follows: can be with reference to figure 3, the increase of gradient or reduce the luminosity of LED in the time that deviation is greater than 10%, ensure surround lighting that visible light sensor detects illumination fiducial value ± 10% scope in; When be greater than illumination fiducial value 110% time, LED lamp is closed.
It should be noted that, the program in above-described MCU, in C language, with easy relatively statement, and the statement such as if or switch can realize, and therefore the program in this MCU belongs to existing method, and therefore, the utility model does not relate to the improvement to method.
Preferably, as shown in Figure 2, visible light sensor 2c has two at least, and in the highly different shell 2a that is arranged on sensor cluster 2, judge processing by logic, can eliminate " bare headed effect " and the impact of window-glass refract light that people causes lamp brightness to change below visible light sensor.
