Description
Technical field
The present invention relates to a kind of Colour-change light source.
Background technology
A lot of as the product of light source with LED in the market, most with circular monochromatic display lamp, and volume is the least, only one or several direct insertion LED lamp bead in lamp, if it is desired to variable color, the light guide plate being mostly required for changing different colours realizes, change light guide plate extremely inconvenient in some place, the most this lamp non-uniform light, some places are bright, some places are dark, and the most indistinctly can see the lamp bead of the inside, because this type of light source all uses and the mounting means of control circuit plate right angle setting LED lamp bead, so LED light source all can not be effectively uniformly distributed on baffle plate by this series products, unsightly, there is no class, dazzling, area is little.
Summary of the invention
The present invention provides a kind of low-power consumption luminous uniformly changeable colour light source, can accomplish to allow uniform light be spread in light guiding film the most dazzling, and user can realize converting the color of this lamellar light source according to actual needs by control circuit.
The technological means of solution problem: the luminous uniformly changeable colour light source of a kind of low-power consumption, including control circuit plate, multiple LED lamp bead it is provided with on control circuit plate, LED lamp bead arranges at least two color, the LED lamp bead of different colours is intervally arranged, and is equipped with reflectance coating between control circuit plate and LED lamp bead, and LED lamp bead is provided above with diffuser plate, being provided with translucent light guiding film on diffuser plate, LED lamp bead is symmetrically distributed in the two ends of diffuser plate.
Described translucent light guiding film is provided above with removable image-text panel.
It is provided with transparent acrylic on described removable image-text panel.
White insulating lacquer layer is scribbled on described control circuit plate.
Described LED lamp bead is square straight cutting lamp bead.
Whether the present invention, by arranging the LED lamp bead of different colours on control circuit plate, is synchronized by bright the opening of the LED of circuit control different colours, i.e. can reach the effect of this light guide plate multiple color conversion, it is not necessary to change light guiding film.The LED lamp bead of different colours is intervally arranged so that light source luminescent is uniform, and color is soft, the positional symmetry of LED lamp bead is distributed in diffuser plate two ends simultaneously, using form head to head to install when LED lamp bead is installed, forming the effect of light correlation, so to be focused on diffuser plate by light.
Accompanying drawing explanation
Fig. 1 is the structural representation one of the present invention.
Fig. 2 is the structural representation two of the present invention.
Fig. 3 is the structural representation three of the present invention.
Detailed description of the invention
As Fig. 1,2, the luminous uniformly changeable colour light source of a kind of low-power consumption, including control circuit plate 1, being provided with multiple LED lamp bead 7 on control circuit plate 1, LED lamp bead 7 arranges at least two color, and the LED lamp bead 7 of different colours is intervally arranged, reflectance coating 2 it is equipped with between control circuit plate 1 and LED lamp bead 7, LED lamp bead 7 is provided above with diffuser plate 3, and diffuser plate 3 is provided with translucent light guiding film 4, and LED lamp bead 7 is symmetrically distributed in the two ends of diffuser plate 3.LED lamp bead 7 uses square straight cutting lamp bead.
The control circuit plate of the present embodiment is only mounted with 6 LEDs lamp bead, the positional symmetry of LED lamp bead is distributed in circuit board two ends, form head to head is needed to install when LED lamp bead is installed, i.e. the inside lateral bend of all LED 90 ° being arranged on 1 control circuit plate and be adjacent to control circuit plate 1, form the effect of light correlation, so to be focused on diffuser plate 3 by light.
nullSix LEDs lamp bead use two kinds of colors simultaneously，Such as red and green，Mode of connection is common anode or common cathode，The lamp bead of two kinds of colors is intervally arranged，If by this plate L1、L3、L4、L6 installs red square LED lamp bead，L2、L5 installs green LED lamp bead，By peripheral control circuits plate 1 control circuit signal，Work as L1、L3、L4、Tetra-lamp bead individually luminescences of L6 are then red，If L2、L5 individually luminescence is then green，If the two luminescence simultaneously, it it is yellow，If wanting to reach more colour switching，Then only control circuit need to be changed，Install red simultaneously、Green、The lamp bead of indigo plant tri-kinds of colors of i.e. RGB，Needs when，Whether the bright synchronization opened of three-color LED light is controlled by circuit，I.e. can reach the effect of this light guide plate multiple color conversion，Without changing light guiding film 4.
Control circuit plate 1 surface need to be coated with one layer of white insullac, in order to reflexed on diffuser plate 3 by light as far as possible；Reflectance coating 2 is that the materials such as white PVC or PE make, in order to reflexed to by uniform light on diffuser plate 3；Diffuser plate is a kind of acrylic that with the addition of optics diffusion material, is also PMMA, and its maximum total light transmittance is up to about 85%, and mist degree reaches more than 93% simultaneously, while guaranteeing high transmission rate, it is thus achieved that optimal light diffusion effect.
Translucent light guiding film 4 selects the materials such as PC or PE of white, and white can be by the light of any color；Translucent light guiding film 4 is provided above with removable image-text panel 5, image-text panel 5 is picture or the word that user needs display, this layer is placed directly in translucent light guiding film 4, luminous by the LED lamp bead of control circuit plate 1 and after reflectance coating 2, diffuser plate 3, translucent light guiding film 4 as backlight, image-text panel 5 is illuminated, to reach to show the picture on this image-text panel 5 or word.
Transparent acrylic 6, acts primarily as two effects, and one is logical light, two has been fixation, this acrylic board thickness as required depending on, but fixing with needs attractive in appearance for convenience, this acrylic board can be processed into many shapes, is oval such as above, is rectangle etc. below.
Such as Fig. 3, during light source uses, LED lamp bead can give off heat, after use time length, the temperature in light source is the highest, in order to be conducive to dispelling the heat, reflectance coating 2 being made structure as shown in Figure 3, each LED lamp bead is provided below a piece of rectangular reflection film, the size of reflectance coating is 10 times of lamellar LED lamp bead area, and LED lamp bead is positioned at the center of rectangular reflection film；Due to the luminous intensity of lamellar LED lamp bead and illumination range more than 95% concentrate on himself within 10 times in the range of, substantially effectively the light that LED lamp bead sends can be reflected up to light guiding film so so arranging, and owing to being greatly reduced the area of reflectance coating so that LED is easier to heat radiation.
