Description
Technical field
The utility model relates to a kind of two light source led Down lamp, belongs to LED lighting technical field.
Background technology
In daily life, consumer has different demands in the different time pair from the colour temperature of illuminating ray, can want light more warm during as winter, wishes that optical fiber feels more refrigerant summer. In order to address this problem, it is also more and more that current LED Down lamp can regulate the light fixture of colour temperature. But most can regulate the internal control circuit of LED Down lamp of colour temperature all comparatively complicated, and cost is higher, and is all to carry out light modulation by mobile phone or remote controller, operates and is not to facilitate especially, especially older to those consumer.
Utility model content
The purpose of this utility model is, a kind of two light source led Down lamp is provided. The light source that it structurally can provide two kinds of different-colours, can switch easily, thereby can meet the demand that colour temperature regulates, and more easy on controlling.
The technical solution of the utility model: two light source led Down lamps, are characterized in: comprise lamp housing, be provided with reflector in lamp housing, leave gap between reflector and lamp housing; In described reflector, be provided with the first LED light source, reflector outside is provided with circle second LED light source; One of them in described the first LED light source and the second LED light source is low color temperature light sources, and another is high color temperature power supply.
In above-mentioned two light source led Down lamps, described the first LED light source is connected with first via Switching Power Supply by the first switching tube; Described the second LED light source is connected with the second way switch power supply by second switch pipe; Described first via Switching Power Supply is connected with switch control chip with the second way switch power supply, and switch control chip is connected with circuit input end with EMI filter circuit by current rectifying and wave filtering circuit successively.
In aforesaid pair of light source led Down lamp, on described switch control chip, be connected with three barricade wall switch, bright and simultaneously bright respectively for controlling two light sources.
In aforesaid pair of light source led Down lamp, on described first via Switching Power Supply and the second way switch power supply, be connected with respectively the first constant current sample circuit and the second constant current sample circuit, for reach constant current object by feedback.
Compared with prior art, the utility model structurally can provide the light source of two kinds of different-colours, and can switch easily, thereby can meet the demand that colour temperature regulates, and also more easy on controlling.
In addition, consumer can just can select the colour temperature of oneself liking by wall switch button, does not need the interface by mobile phone A PP, also does not need to pass through remote controller. Of the present utility model easy to assembly, be easily understood, child Yi Ke carries out light adjusting. And the utility model is by power supply integration, does not need external power supply or other external circuitses.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is electrical block diagram of the present utility model.
Being labeled as in accompanying drawing: 1-lamp housing, 2-reflector, 3-the first LED light source, 4-the second LED light source.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment. Two light source led Down lamps, as shown in Figure 1: comprise lamp housing 1, in lamp housing 1, be provided with reflector 2, between reflector 2 and lamp housing 1, leave gap; In described reflector 2, be provided with the first LED light source 3, reflector 2 outsides are provided with circle second LED light source 4; One of them in described the first LED light source 3 and the second LED light source 4 is low color temperature light sources (3000K), and another is high color temperature power supply (6000K).
Described the first LED light source 3 is connected with first via Switching Power Supply by the first switching tube; Described the second LED light source 4 is connected with the second way switch power supply by second switch pipe; Described first via Switching Power Supply is connected with switch control chip with the second way switch power supply, and switch control chip is connected with circuit input end with EMI filter circuit by current rectifying and wave filtering circuit successively. On described switch control chip, be connected with three barricade wall switch. On described first via Switching Power Supply and the second way switch power supply, be connected with respectively the first constant current sample circuit and the second constant current sample circuit. Circuit structure as shown in Figure 2.
The mode of operation that the utility model can be realized is as follows.
Switch on wall is because there are three gears, and by the positive white light of the bright 6000K of light fixture after 1 gear, after the 3s of interval, again by 2 position switch, light fixture is converted to bright 3000K warm white, and after the 3s of interval, by 3 position switch, the positive white light of light fixture and warm white are simultaneously bright, and colour temperature can reach 4000K left and right.
Power supply has two-way output, controls the output respectively of double switch power supply by switch control chip, reaches constant current object by feedback circuit, within the scope of alternating voltage 100-240V, can use. After switch keeps off by 1, switch control chip control 1 way switch power supply output, positive white light lights, after 2 gears, positive white light Switching Power Supply is cut off, 2 way switch power supplys are started working, and warm white lights, after 3 gears, 2 way switch power supplys work on, and 1 way switch power supply is also started working, positive white light and warm white all light, and reach the light mixing effect that people need.
The change of the variation of shape, size, material, color and combination to product on basis of the present utility model, the utility model product monnolithic case size, color is all in the present invention's scope required for protection.
