Abstract
The utility model an LED-based multicolor fancy lamp structure, and the luminous portion of the utility model is formed by an LED array, essentially characterized in that: the LED array consists of a plurality of light-emitting units of the same arrangement structure; each light-emitting unit is provided with at least a red LED, a green LED and a blue LED; within the same light-emitting unit, such an interval is maintained among the LEDs that the luminous spots of all LEDs form overlapped images in the eyes of those who watch the lamp; the center-to-center distance between each two adjacent light-emitting units is the same, and complies with the formula of: D is more than or equal to 2 <*> L <*> tan (Theta/2), wherein D represents the minimum center-to-center distance between each two adjacent light-emitting units; L represents the vertical distance from the speculating spot to the luminous portion of the fancy lamp in normal use; Theta is the minimum resolution angle of human eyes. The LED array being of the abovementioned characteristics, a control circuit can be used to make the fancy lamp to emit lights of rich colors.
Description
Technical field
The utility model relates to fitting structure, particularly is mainly used in the colorful LED ornament lamp structure of commodity display, show window illumination.
Background technology
Existing LED-based colorful ornament lamp is called " light emitting diode rainbow lamp " utility model patent as 98212208.X number,, and its luminous site is the lamp string that is connected to form by some light emitting diodes that is wrapped in the tubular shell.This structure as a luminescence unit, makes the luminous site of ornament lamp can only wholely show certain color whole lamp string.At present, a kind of LED-based colorful ornament lamp is abroad also arranged, this lamp is bar shaped, the arrangement of red, green, blue sequence period is pressed by many light emitting diodes in its luminous site, but still be to look whole the luminous site of ornament lamp as a whole, only design the arrangement mode of light emitting diode from the color matching effect of whole luminous site, therefore colour mixture can't realize that all red, green, blue three primary colours in the system of chromatic coordinates surround all colours in the visible region in any case, display mode dullness, color are abundant inadequately.
Summary of the invention
The purpose of this utility model provides a kind of colorful LED ornament lamp that demonstrates rich colors.
The utility model is achieved in that colorful LED ornament lamp comprises the luminous site that is made of light emitting diode matrix, especially, light emitting diode matrix is made of the identical luminescence unit of a plurality of arrangement architectures, and each luminescence unit is arranged with a red light emitting diodes, a green LED and a blue LED at least; In same luminescence unit, the light-emitting diodes tube pitch makes that hot spot imaging in audience's eye of all light emitting diodes is overlapping; The centre-to-centre spacing of adjacent luminescence unit is identical, and this centre-to-centre spacing satisfies following formula: D 〉=2
*L
*Tan (θ/2), D is the minimum centers-distance of adjacent luminescence unit in the formula, and L watches some the vertical range with the luminous site of ornament lamp during for normal the use, and θ is the human eye angle of minimum resolution.Because light emitting diode matrix of the present utility model has above-mentioned arrangement characteristics, therefore can make ornament lamp demonstrate abundant colors by control circuit.For example can independently control the grey level of three kinds of light emitting diodes in each luminescence unit, that is control three kinds of shared ratios of color of red, green, blue in each luminescence unit, just can make each luminescence unit mix multiple different color, if the luminescence unit that inner control is different at one time demonstrates different colors, just can make the whole luminous site of ornament lamp present colorful effect.
The utility model has the advantages that displayable color effect is not subjected to the restriction of light emitting diode self color, only need just can change the display color of ornament lamp by suitable control circuit, and need not to change light emitting diode, and only need adjust control program and just can realize the dynamic continually varying effect of color, and need not to change the array structure of luminescence unit and the arrangement architecture of luminescence unit interior light emitting diodes.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, wherein:
Fig. 1 is contour structures embodiment of the present utility model;
Fig. 2 is the light emitting diode arrangement architecture schematic diagram that direction is seen of overlooking from Fig. 1;
Fig. 3 is another embodiment of light emitting diode arrangement architecture.
The specific embodiment
Referring to Fig. 1, the profile of the colorful LED ornament lamp of present embodiment is roughly half round post, and its luminous site is row's light emitting diode matrix.Referring to Fig. 2, light emitting diode matrix is made of a plurality of luminescence units simultaneously, and each square frame of broken lines is represented a luminescence unit among the figure, and the arrangement architecture of each luminescence unit is identical.In same luminescence unit, the light-emitting diodes tube pitch should make as far as possible that hot spot imaging in audience's eye of all light emitting diodes is overlapping, to reach uniform color matching effect; The centre-to-centre spacing of adjacent luminescence unit is identical, and this centre-to-centre spacing satisfies aforesaid expression formula, and the audience being is normally is being viewed and admired under the distance, clearly tells the color that adjacent luminescence unit shows.
The luminescence unit of present embodiment is made of two red light emitting diodes 1 and 2, green LEDs 3 and a blue LED 4, four light emitting diodes are arranged in rectangle, and two red light emitting diodes 1 and 2 are positioned on same the diagonal.Adopt this structure can make luminescence unit have the effect of matching colors preferably.The number of the red, green, blue light emitting diode in the in fact single luminescence unit can should make the homochromy light emitting diode in the same unit spaced apart according to the needs adjustment of practical application as far as possible in the arrangement, even to avoid irregular colour.
Be arranged in order " one " font by linear between the luminescence unit of present embodiment, can certainly be arranged in other shape, multiple linear as annular, arc etc., and plane, sphere etc. are multiple planar.Fig. 3 illustrates the embodiment that is arranged in annular, each square frame of broken lines is represented a luminescence unit among the figure, each luminescence unit also is made of two red light emitting diodes 1 and 2, green LEDs 3 and a blue LED 4, and four light emitting diodes are arranged in rectangle.Can adopt the mode of control dutycycle to the control mode of light emitting diode, promptly drive light emitting diode with digital pulse signal, dutycycle by regulating impulse, just the on-state rate by light emitting diode in the control unit interval obtains different tonal gradations, thereby reaches the purpose of toning.
