The non-linear light modulation LED illuminating lamp has the advantages of simple light modulation mode and low cost, and is benefit for popularization and application of the light modulation LED illuminating lamp.
Description
Technical field
The utility model belongs to the lighting technical field, relates to the LED illuminating lamp, relates in particular to dimming LED illuminating lamp.
Background technology
As a kind of green, hommization, energy-conserving and environment-protective lighting system, the LED illumination is applied in every field more and more.At present, existing LED illuminating lamp scarcely can carry out brightness regulation, but need to carry out according to environment the adjusting of LED lighting brightness in a lot of illumination occasions.
The light modulation of LED illuminating lamp is to adopt the linearity light adjusting mode, for example utilizes controllable silicon to carry out light modulation.The dimming scope 0-100% of linearity light adjusting mode.But in the actual illumination application scenario, the client does not need the light modulation of illumination from 0 to 100% basically, only needs several illumination shelves to get final product.And the linearity light adjusting cost compare is expensive, and this just causes present light modulation dimming LED illuminating lamp to be difficult to allow the client accept.
The utility model content
For this reason, technical problem to be solved in the utility model is to provide dimming mode non-linear dimming LED illuminating lamp simple, with low cost, the deficiency that exists to overcome prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of non-linear dimming LED illuminating lamp, it comprises fluorescent tube, is positioned at the circuit base plate of fluorescent tube, and the plurality of LEDs light-emitting component on circuit base plate of gathering, it is characterized in that: described plurality of LEDs light-emitting component is divided into a plurality of LED lighting units, the LED light-emitting component of each LED lighting unit is the even mixed distribution of intersecting mutually, and each LED lighting unit all has the drive circuit that oneself independently includes switch.
In concrete execution mode of the present utility model, described plurality of LEDs light-emitting component is divided into 3-9 LED lighting unit, like this, just can realize 3 to 9 grades of light modulation brightness.
In the utility model embodiment, the drive circuit of described each LED lighting unit all is connected on same driving power.Like this, adopting same driving power is each LED lighting unit power supply, can further save cost.
adopt technique scheme, described plurality of LEDs light-emitting component is divided into a plurality of LED lighting units, the LED light-emitting component of each LED lighting unit mutually evenly intersects and mixes, and each LED lighting unit all has the drive circuit that oneself independently includes switch, so just can realize by the switching of controlling each LED lighting unit the light modulation purpose, if all LED lighting units are closed, whole illuminating lamp is just closed, if light a LED lighting unit, just can realize first order light modulation brightness, if light two LED lighting units, just can realize second level light modulation brightness, so, can be as required, realize multistage light modulation brightness, when all LED lighting units are all lighted, just reach the brightest degree.This dimming mode only needs a plurality of switches just can realize multistage light modulation, and do not need expensive light modulation device, therefore, non-linear dimming LED illuminating lamp of the present utility model has advantages of that dimming mode is simple, with low cost, is beneficial to applying of dimming LED illuminating lamp more.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Fig. 1 is the online road of LED light-emitting component of the present utility model distribution schematic diagram basically;
Fig. 2 is that circuit of the present utility model is controlled schematic diagram;
In figure:
The 100-circuit base plate, 200-LED light-emitting component, 201-switch, 300-driving power.
Embodiment
As shown in Figure 1, non-linear dimming LED illuminating lamp of the present utility model, it comprises the fluorescent tube (not shown), is positioned at the circuit base plate 100 of fluorescent tube, and the plurality of LEDs light-emitting component 200 on circuit base plate of gathering, the plurality of LEDs light-emitting component is divided into a plurality of LED lighting units, as in the present embodiment, 4 LED lighting units have been divided into, i.e. LED lighting unit A, B, C, D.The LED light-emitting component of each LED lighting unit is the even mixed distribution of intersecting mutually, the distribution situation of LED light-emitting component on circuit base plate 100 for each LED lighting unit of clear expression in Fig. 1, LED element in LED lighting unit A represents with circle, LED element in LED lighting unit B represents with triangle, LED element in LED lighting unit C represents with square, and the LED element in LED lighting unit C represents with pentalpha.
In conjunction with shown in Figure 2, each LED lighting unit A, B, C, D all have the drive circuit that oneself independently includes switch 201, and drive circuit all is connected on same driving power 300 again.Driving power includes power factor correction module, power driver module and constant-current source, because driving power is prior art, therefore here just no longer describes in detail.
in the utility model, described plurality of LEDs light-emitting component is divided into a plurality of LED lighting units, the LED light-emitting component of each LED lighting unit mutually evenly intersects and mixes, and each LED lighting unit all has the drive circuit that oneself independently includes switch, so just can realize by the switching of controlling each LED lighting unit the light modulation purpose, if all LED lighting units are closed, whole illuminating lamp is just closed, if light a LED lighting unit, just can realize first order light modulation brightness, if light two LED lighting units, just can realize second level light modulation brightness, so, can be as required, realize multistage light modulation brightness, when all LED lighting units are all lighted, just reach the brightest degree.This dimming mode only needs a plurality of switches just can realize multistage light modulation, and does not need expensive light modulation device.
Therefore, non-linear dimming LED illuminating lamp of the present utility model has advantages of that dimming mode is simple, with low cost, is beneficial to applying of dimming LED illuminating lamp more.
