Abstract
The utility model relates to a mixed-type LED (light-emitting diode) backlight source, which comprises an LED lamp bar and at least one main LED. The main LEDs are arranged uniformly on the LED lamp bar, at least one auxiliary LED is arranged between adjacent main LEDs, the color gamut of the main LEDs is identical to the color gamut of the auxiliary LEDs, the auxiliary LEDs have at least one model, the power of the auxiliary LEDs is lower than the power of the main LEDs, the auxiliary LEDs between the main LEDs are arranged uniformly along the LED lamp bar, and each main LED and each auxiliary LED are correspondingly provided with a separate power supply. The mixed-type LED backlight source not only saves the energy and achieves high utilization rate of light sources, but also has no color drifting, and modules can form dynamic response.
Description
Technical field
The utility model relates to a kind of LED-backlit source, relates in particular to a kind of formula LED-backlit source that is mixed, and specifically is applicable to the light source that provides backlight is provided.
Background technology
At present LED-backlit source lamp bar adopts LED with a kind of model to be regular continuously arranged mode the light source that provides backlight is provided mostly.
The Chinese patent Granted publication number is CN201318595Y, Granted publication day is the LED-backlit source that the utility model patent on September 30th, 2009 discloses a kind of railway locomotive electric measuring instrument, comprise backlight and be arranged on the row of two on this backlight or the above LED luminous tube that is connected with power supply of two row, whenever walk to and comprise two or more LED luminous tubes less, LED luminous tube between every row is connected in series, and is connected in parallel between the LED luminous tube between row and the row.Though this utility model can realize the even, unified of illumination effect by rational layout, but this kind design is owing to used more great power LED, at first can waste energy, not energy-conservation, secondly can bring look to float problem, in addition, also can produce the heat spot problem owing to the quantity of great power LED is more, thereby need to increase the distance between LED lamp usage quantity and LED and the light plate, this can cause and use the limitation and the wasting of resources, reduces the light source utilization rate.
The utility model content
The purpose of this utility model is to overcome wasting energy of existing in the prior art, look floats, the light source utilization rate is lower defective and problem, the formula that the is mixed LED-backlit source of provide a kind of and save the energy, colourlessly float, the light source utilization rate is higher.
For realizing above purpose, technical solution of the present utility model is: a kind of formula LED-backlit source that is mixed, comprise LED lamp bar and main LED, the quantity of described main LED is at least one, and on LED lamp bar, evenly be provided with, be provided with at least one secondary LED between the described main LED, and the colour gamut of secondary LED be identical with the colour gamut of main LED, the model of secondary LED is at least a kind of, and the power of secondary LED is less than the power of main LED.
The model of described secondary LED is one to five kind.
The model of described secondary LED is two kinds.
The secondary LED that is provided with between the described main LED evenly is provided with along LED lamp bar, and last each correspondence of each main LED, secondary LED disposes an independent current source.
Compared with prior art, the beneficial effects of the utility model are:
1. owing on LED lamp bar, be provided with main LED and secondary LED simultaneously in a kind of formula LED-backlit source that is mixed of the utility model, and secondary LED evenly is provided with between main LED, this kind design has not only reduced the usage quantity of main LED, and reduced spacing distance between main LED and the LED lamp bar, the usage quantity that reduces main LED can reduce the usage quantity of great power LED, can save the energy, and avoid the generation of heat spot, the spacing distance that reduces between main LED and the LED lamp bar can improve the light source utilization rate.Therefore the utility model is not only saved the energy, and the light source utilization rate is higher.
2. because the secondary LED that is provided with between main LED in a kind of formula LED-backlit source that is mixed of the utility model has identical colour gamut with main LED, and the model of secondary LED and quantity can have multiple, the look that therefore can effectively solve single high-power main LED and brought floats problem, and owing to all supportingly on each LED be provided with an independent current source, thereby the size of current that can regulate each LED according to the variation of surrounding environment, thereby adjust the brightness of each LED, and then make the whole LED backlight source module to carry out dynamic response surrounding environment.Therefore the utility model is not only colourless floats, and module can form dynamic response.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: LED lamp bar 1, main LED 2, secondary LED 3.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is described in further detail
Referring to Fig. 1, a kind of formula LED-backlit source that is mixed, comprise LED lamp bar 1 and main LED2, the quantity of main LED2 is at least one, and evenly be provided with on LED lamp bar 1, special feature of the present utility model is to be provided with at least one secondary LED3 between the main LED2, and the colour gamut of secondary LED3 is identical with the colour gamut of main LED2, the model of secondary LED3 is at least a kind of, and the power of secondary LED3 is less than the power of main LED2.
The model of preferred secondary LED3 is one to five kind, and further the model of preferred secondary LED3 is two kinds.
The secondary LED3 that is provided with between the preferred main LED2 evenly is provided with along LED lamp bar 1, and last each correspondence of each main LED2, secondary LED3 disposes an independent current source.
During use, carrying out illuminated in combination by the LED with various models, quantity and the power of colour gamut under situation commonly used to provide the light source for backlight, can also regulate the size of current of each LED according to the variation of surrounding environment, thereby adjust the brightness of each LED, and then make the whole LED backlight source module to carry out dynamic response surrounding environment.
As from the foregoing, the utility model is not only saved the energy, the light source utilization rate is higher, and colourlessly float, module can form dynamic response.
The above only is a better embodiment of the present utility model; protection domain of the present utility model does not exceed with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
