Abstract
The invention discloses an encapsulating method of an LED light source adjustable in color temperature, color rendering index and brightness. The method includes the following steps that 1, a red-light chip with 620-625nm wavelength and a blue-light chip with 455-457.5nm wavelength are fixed onto an anode return circuit of an aluminum substrate and a cathode return circuit of the aluminum substrate respectively; 2, the red-light chip is connected with the anode of the anode return circuit and the cathode of the anode return circuit through gold wires, and the blue-light chip is connected with the anode of the cathode return circuit and the cathode of the cathode return circuit; 3, the red-light chip is encapsulated well through green fluorescent glue; 4, the blue-light chip and the red-light chip which is encapsulated well through the green fluorescent glue are encapsulated in an encapsulation body together through transparent silica gel. LED light sources produced through the encapsulating method of the white-light LED light source are convenient and fast to use, and the application range of the LED light sources is enlarged.
Description
Technical field
The present invention relates to a kind of method for packing of LED light source, relate in particular to the method for packing of the white LED light source of a kind of adjustable color temperature and color rendering index and brightness.
Background technology
At present along with LED light source application is more and more extensive, in the industry cycle everybody is also more and more to the LED light source research of tunable optical, but substantially all there are some defects in technology at present, many times LED light source can only single adjustment colour temperature and single adjustment color rendering index or brightness, and color rendering index adjusting range is inadequate.
Summary of the invention
Technical problem to be solved by this invention is: the method for packing of the white LED light source of a kind of adjustable color temperature and color rendering index and brightness is provided, and the LED light source that uses the method to produce, not only easy to use, and can improve the range of application of LED light source.
Solve this technical problem, technical scheme of the present invention is: the method for packing of the LED light source of a kind of adjustable color temperature and color rendering index and brightness, comprises the steps:
The blue chip that step 1, the red light chips that is 620-625nm a wavelength and wavelength are 455-457.5nm is separately fixed on two positive poles and negative loop on aluminium base;
Compared with prior art, the beneficial effect that the present invention has is:
1, the LED light source that adopts the present invention to produce, by green emitting phosphor, excite gold-tinted that red light chips produces, by gold-tinted and blue chip, mix and produce white light again, by regulating the input current size of ruddiness to control colour temperature and development index, by controlling blue chip input current, control brightness.
2, the LED light source that adopts the present invention to produce, owing to being two completely independently parallel circuitss, therefore can better adjust as required colour temperature and development index and the brightness of white light, and because red light chips brightness is adjustable, to color rendering index, control convenient.Under low colour temperature high color rendering index (CRI), brightness also can be higher, can reduce to drive and control cost during to downstream illumination application.

Embodiment bis-
As shown in Figure 1, the method for packing of the LED light source of a kind of adjustable color temperature and color rendering index and brightness, comprises the steps:
The blue chip that step 1, the red light chips that is 623nm a wavelength and wavelength are 456nm is separately fixed on two positive poles and negative loop on aluminium base;
Embodiment tri-
As shown in Figure 1, the method for packing of the LED light source of a kind of adjustable color temperature and color rendering index and brightness, comprises the steps:
The blue chip that step 1, the red light chips that is 625nm a wavelength and wavelength are 457.5nm is separately fixed on two positive poles and negative loop on aluminium base;
The LED light source that adopts the present invention to produce, by green emitting phosphor, excite gold-tinted that red light chips produces, by gold-tinted and blue chip, mix and produce white light again, by regulating the input current size of ruddiness to control colour temperature and development index, by controlling blue chip input current, control brightness.
The LED light source that adopts the present invention to produce, owing to being two completely independently parallel circuitss, therefore can better adjust colour temperature and development index and the brightness of white light as required, and because red light chips brightness is adjustable, to color rendering index, controls convenient.Under low colour temperature high color rendering index (CRI), brightness also can be higher, can reduce to drive and control cost during to downstream illumination application.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the variation of the above embodiment, modification, all will drop within the scope of claim of the present invention.
