Description
Technical field
The utility model relates to LED decorative lighting field, and a kind of specifically is light source, the dynamic LED striation that can adjust colour temperature along with the variation of environment with dynamic white light LED.
Background technology
Because the LED light fixture has energy-saving and environmental protection and long service life, the application of LED lamp decoration is day by day extensive.The LED lamp decoration is more and more used in office lighting, residential lighting, industrial building illumination etc.
We know that variation of temperature is to make the people produce the immediate cause of changes in temperature sensation, and except variation of temperature, different colors also can make us produce different changes in temperature impressions.Produce a kind of warm sensation such as observing when us orange the time toward the contact meeting, tend to produce a kind of chilly sensation blue the time and observe.When people are in the luminous environment of low colour temperature, have a kind of happy, comfort that body and mind loosens; The luminous environment of high colour temperature, the anxiety sense that can make the people keep excitement, vigilance, notice to concentrate and produce appropriateness.White light LEDs striation of the prior art is to produce dynamic effect by circuit control signal, and cost is relatively more expensive.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of dynamic white light LED striation, can arbitrarily change colour temperature pairing the most suitable tone when satisfying varying environment, mood, and cost is low, it is simple to implement.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of dynamic white light LED striation comprises flexible PCB, is welded in LED lamp on the circuit board, the current-limiting resistance of driving LED lamp, is welded in the lead at flexible PCB two ends; It is characterized in that: be provided with three or above blue led chip in the described LED lamp, be equipped with the fluorescent material glue-line of different proportionings on described each blue led chip; Described each blue led chip all is equipped with the bowl cup, and the blue led chip is located in the bowl cup, is provided with separation layer between the described bowl cup; Every next but two or the LED lamp more than two are provided with a current-limiting resistance on the described flexible PCB; Described flexible PCB is provided with one deck layer of silica gel.Blue led chip excitated fluorescent powder glue-line can send white light, and the blue led chip with fluorescent material glue-line of different proportionings sends the white light of different-colour.The white light of the multi beam different-colour in the LED lamp mixes and forms a branch of mixed white light, the colour temperature of the white light that is sent by each blue led chip that changes in the LED lamp, thus make the set out white light of different-colour of LED lamp, realize the dynamic white light effect of striation.Separation layer makes that with the bowl cup each blue led chip is separate, sends the white light of different-colour separately.Silica gel has the excellent waterproof anti-corrosive properties, and circuit is avoided destroying in the protection LED striation, makes that the striation scope of application is wider.
As improvement, be provided with a current-limiting resistance every three LED lamps on the described flexible PCB.
As improvement, described LED lamp is chip low-power LED lamp or chip high-powered LED lamp.
As improvement, three blue led chips are arranged in the described LED lamp.
The beneficial effect that the utility model is compared with prior art brought is:
Be provided with a plurality of blue led chips in the LED lamp in the striation, each blue led chip sends the white light of different-colour, the white light of different-colour mixes a branch of mixed white light of formation in the LED lamp, by changing the luminosity that each has the blue led chip of different-colour, thereby make the LED lamp send the mixed white light of different-colour, realize the dynamic white light effect of LED striation.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a LED modulated structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, a kind of dynamic white light LED striation comprises flexible PCB 4, is welded in LED lamp 2 on the circuit board 4, the current-limiting resistance 3 of driving LED lamp 2, is welded in the lead 1 at flexible PCB 4 two ends; As shown in Figure 2, be provided with three or above blue led chip 5 in the described LED lamp 2, be provided with 5, three blue led chips 5 of three small-power chip blue led chips in the LED lamp 2 in the present embodiment and in LED lamp 2, evenly distribute, and be on the same circumference, become hexagonal angle between the adjacent chips.Be equipped with the fluorescent material glue-line (not indicating) of different proportionings on described three blue led chips 5, described blue led chip 5 is located in the bowl cup 7 together with the fluorescent material glue-line, be provided with separation layer 6 between described three bowl cups 7, bowl cup 7, separation layer 6 make that each blue led chip 5 is separate.
The dynamic white light effect operation that realizes striation is as follows: lead 1 is inserted power supply, because at every next but two on the circuit board 4 or current-limiting resistance 3 of 2 series connection of the LED lamp more than two, current-limiting resistance 3 of each three LED lamps, 2 series connection in the present embodiment, promptly a current-limiting resistance 3 can drive three LED lamps 2, after three blue led chips 5 in the LED lamp 2 were driven, luminous and excitated fluorescent powder glue-line sent white light; Three blue led chips 5 are because of being equipped with the fluorescent material glue-line of different proportionings, and three blue led chips 5 excite the fluorescent material glue-line of different proportionings to send the white light of different-colour.The white light of the three beams different-colour in the LED lamp 2 mixes a branch of mixed white light of formation, the colour temperature of this mixed white light is in LED lamp 2 between the three beams white light colour temperature, by changing the drive current of three blue led chips 5, regulate the brightness of the white light that three blue led chips 5 send, thereby change the mixed light effect of the white light of three beams different-colour.If will obtain the white light of high colour temperature, increase the drive current that has the blue led chip 5 of higher color temperature in the LED lamp 2, reduce the drive current of blue led chip 5 simultaneously with low colour temperature, behind the mixed light LED lamp 2 embodied is high color temperature white light; If will obtain the white light of low colour temperature, increase the drive current that has the blue led chip 5 of low colour temperature in the LED lamp 2, reduce the drive current of blue led chip 5 simultaneously with higher color temperature, behind the mixed light LED lamp 2 embodied is low color temperature white light.
In the utility model, be provided with a plurality of blue led chips 5 in the LED lamp 2, each blue led chip 5 sends the white light of different-colour, the white light of different-colour mixes a branch of mixed white light of formation in LED lamp 2, by changing the luminosity that each has the blue led chip 5 of different-colour, thereby make LED lamp 2 send the mixed white light of different-colour, realize the dynamic white light effect of LED striation.All have the utility model structure, and just do to change, all belong to protection category of the present utility model. in form
