The specific embodiment
Please see figures.1.and.2 simultaneously, Fig. 1 is the function block schematic diagram that illustrates according to the light emitting diode illuminating apparatus 100 of the utility model embodiment, and Fig. 2 is the structural representation that illustrates according to the light-emitting diode (LED) module 130 of the utility model embodiment.
Light emitting diode illuminating apparatus 100 comprises switch 110, driver 120 and light-emitting diode (LED) module 130.Switch 110 is to use for the user to carry out change action, with photochromic (or colour temperature) of adjustment light emitting diode illuminating apparatus 100.In the present embodiment, switch 110 can be rocker switch as shown in Figure 3, but the embodiment of the utility model is not limited to this.Light-emitting diode (LED) module 130 comprises a plurality of LED optical strips (LED light bar) groups (for example LED optical strip group 132,134) and light mixing device 136.LED optical strip group 132 and 134 is adjacent to light mixing device 136, to utilize light mixing device 136 light that LED optical strip group 132,134 is sent is mixed.In the present embodiment, light mixing device 136 can be the LGP of rectangle, but the embodiment of the utility model is not limited to this.
In light-emitting diode (LED) module structure shown in Figure 2; LED optical strip group 132 comprises LED optical strip 132a and 132b; And LED optical strip group 134 comprises LED optical strip 134a and 134b, all is provided with a plurality of light-emitting diode chip for backlight unit LCDC on each LED optical strip.In the present embodiment; The LED optical strip 132a of LED optical strip group 132 and 132b are two relative side (or claiming side surface) 136a and the 136c that is adjacent to light mixing device 136; And the LED optical strip 134a of LED optical strip group 134 and 134b are two relative side 136b and the 136d in addition that is adjacent to light mixing device 136, but the LED optical strip arrangement mode of the utility model embodiment is not limited to this.In other embodiment of the utility model; The LED optical strip 132a of LED optical strip group 132 and 132b can be adjacent to two adjacent side 136a and 136b of light mixing device 136, and the LED optical strip 134a of LED optical strip group 134 and 134b can be adjacent to two adjacent side 136c and 136d of light mixing device 136.
In the present embodiment, driver 120 comprises counter 122 and selects module 124.Counter 122 is the switching times in order to record user change-over switch; The switching times of selecting module 124 then to be write down according to counter 122 comes optionally LED optical strip group 132 and 134 to be electrically connected to the external power source device; Providing electrical power to corresponding LED optical strip group, and make it luminous.
The selection module 124 of present embodiment can be made up of a plurality of transistor switch.These transistor switches are to be controlled by counter 122, open or close with the control signal of being exported according to counter 122.
In addition, the driver of the utility model embodiment is not limited to open simultaneously all LED optical strips in the LED optical strip group.In other embodiment of the utility model, driver can only be opened a LED optical strip in the LED optical strip group.For example, when the user was switched rocker switch 1 time, driver 120 can correspondingly be opened the LED optical strip 132a in the LED optical strip group 132.Again for example, when the user was switched rocker switch 2 times, driver 120 can correspondingly be opened the LED optical strip 132b in the LED optical strip group 132.Again for example, when the user was switched rocker switch 3 times, driver 120 can correspondingly be opened LED optical strip 132a and the 132b in the LED optical strip group 132.
It should be noted that; Because the light-emitting diode (LED) module 130 of the utility model embodiment includes light mixing device 136; Therefore when LED optical strip 132a and 132b open simultaneously; Light mixing device 136 can mix the light of LED optical strip 132a and 132b, and light-emitting diode (LED) module 130 at this moment photochromic (or colour temperature) can be different from single LED optical strip (132a or 132b) photochromic when luminous.
Please with reference to Fig. 3, it is the schematic flow sheet that illustrates according to the driving method 300 of the light emitting diode illuminating apparatus 100 of the utility model embodiment.In driving method 300, at first carry out switch step 310, so that being provided, above-mentioned switch 110 supply the user to switch, with the light color of adjustment light emitting diode illuminating apparatus 100.Then, carry out counting step 320, to calculate the number of times of user's change-over switch 110.In the present embodiment, the number of times of user's change-over switch 110 is meant that switch 110 is switched to the number of times of " unlatching " state.Please with reference to Fig. 4, it is the structural representation that illustrates according to the switch 110 of the utility model embodiment.The surface of switch 110 has Warning Mark " on ", this sign be representative when the user presses the seesaw of " on " this side, switch 110 meetings " unlatching ", and provide electrical power to light-emitting diode (LED) module 130 through driver.
Please get back to Fig. 3; After counting step 320; Then select step 330, to come optionally to provide electrical power at least one of LED optical strip group (or LED optical strip) according to the switching times that counter was write down, so that LED optical strip group is luminous.Then, carry out mixed light step 340, come the photochromic of mixed luminescence diode optical strip group to utilize light mixing device.
Can know the dimming mode that light emitting diode illuminating apparatus 100 and the driving method 300 that the utility model embodiment is provided provided convenience by above explanation.The user only needs change-over switch can adjust light emitting diode illuminating apparatus 100.Moreover light emitting diode illuminating apparatus 100 utilizes light mixing device to come the light of mixed luminescence diode optical strip, and so light emitting diode illuminating apparatus 100 just can provide diversified photochromic confession user to select.For example; Light emitting diode illuminating apparatus 100 can comprise red light emitting diodes striation, blue LED striation and green LED striation; So light emitting diode illuminating apparatus 100 not only can provide redness, basket look and green light, more magenta, yellow, cyan and white light can be provided.
Please with reference to Fig. 5, it is the structural representation that illustrates according to the light-emitting diode (LED) module 530 of another embodiment of the utility model.Light-emitting diode (LED) module 530 is to be similar to light-emitting diode (LED) module 130, but different to be in the LED optical strip group 132 of light-emitting diode (LED) module 530 and 134 LED optical strip be the same side that is arranged at light mixing device 136.For example; The LED optical strip 132a of LED optical strip group 132 and the LED optical strip 134a of LED optical strip group 134 are the side 136a that are adjacent to light mixing device 136, and wherein LED optical strip 132a and 134a are provided with parallel to each other.Again for example; The LED optical strip 132b of LED optical strip group 132 and the LED optical strip 134b of LED optical strip group 134 are the side 136c that are adjacent to light mixing device 136, and wherein LED optical strip 132b and 134b are provided with parallel to each other.
Though the LED optical strip arrangement mode of the light-emitting diode (LED) module 530 of present embodiment and light-emitting diode (LED) module 130, the function of light-emitting diode (LED) module 530 does not have different with effect compared to light-emitting diode (LED) module 130.
Though the utility model discloses as above with several embodiment; Right its is not in order to limit the utility model; Any in the technical field under the utility model have a common knowledge the knowledgeable; In spirit that does not break away from the utility model and scope, when can doing various changes and retouching, so the protection domain of the utility model is as the criterion when looking the scope that appending claims defines.
