Abstract
The invention discloses an even-lighting variable-color light source with low power consumption. The light source comprises a control circuit board. A plurality of LEDs are disposed on the control circuit board and are at least in two colors. The LEDs different in color are arranged at intervals. Reflecting film is arranged between the control circuit board and the LEDs. A diffusion plate is disposed above the LEDs. Semitransparent light guide film is disposed on the diffusion plate. The LEDs are symmetrically disposed at two ends of the diffusion plate. The LEDs different in color are disposed on the control circuit board and are synchronously turned on under circuit control, so that a light guide plate can change in various colors with no need for change of the light guide film. The LEDs different in color are arranged at intervals, so that light from the light source is even. The LEDs are also symmetrically distributed at two ends of the diffusion plate and are installed end to end to allow light to mutually irradiate, so that the light can be concentrated to the diffusion plate.
Description
?
Technical field
The present invention relates to a kind of Colour-change light source.
Background technology
Use in the market LED a lot of as the product of light source, maximum with the monochromatic indicator lamp of circle, and volume is all less, only have one or several direct insertion LED lamp pearls in lamp, if think variable color, mostly all need the LGP of changing different colours to realize, change LGP extremely inconvenient in some place, this lamp non-uniform light in addition, some places are bright, some places are dark, and the lamp pearl inside indistinctly seeing from the outside, because this type of light source all adopts the mounting means with control circuit board at right angle setting LED lamp pearl, so this series products all can not effectively be uniformly distributed on baffle plate by LED light source, not attractive in appearance, there is no class, dazzling, area is little.
Summary of the invention
The invention provides the luminous even changeable colour light source of a kind of low-power consumption, can accomplish to allow light evenly be spread in light guiding film simultaneously not dazzling again, and the user can according to actual needs, realize converting the color of this sheet light source by control circuit.
The technological means of dealing with problems: the luminous even changeable colour light source of a kind of low-power consumption, comprise control circuit board, be provided with a plurality of LED lamp pearls on control circuit board, LED lamp pearl arranges at least two kinds of colors, the LED lamp pearl of different colours is intervally arranged, and between control circuit board and LED lamp pearl, is equipped with reflectance coating, above LED lamp pearl, is provided with diffuser plate, be provided with translucent light guiding film on diffuser plate, LED lamp pearl is symmetrically distributed in the two ends of diffuser plate.
Be provided with removable image-text panel above described translucent light guiding film.
Be provided with transparent acrylic on described removable image-text panel.
Be coated with adularescent insulated paint layer on described control circuit board.
Described LED lamp pearl is square straight cutting lamp pearl.
The present invention is by arranging the LED lamp pearl of different colours on control circuit board, whether LED lamp bright of controlling different colours by circuit opens synchronously, can reach the effect of this LGP multiple color conversion, without changing light guiding film.The LED lamp pearl of different colours is intervally arranged, and makes light source luminescent even, and color is soft, the position of LED lamp pearl is symmetrically distributed in to the diffuser plate two ends simultaneously, when LED lamp pearl is installed, adopt form head to head to install, form the effect of light correlation, like this in order to light is focused on diffuser plate.
The accompanying drawing explanation
Fig. 1 is structural representation one of the present invention.
Fig. 2 is structural representation two of the present invention.
Fig. 3 is structural representation three of the present invention.
The specific embodiment
As Fig. 1,2, the luminous even changeable colour light source of a kind of low-power consumption, comprise control circuit board 1, be provided with a plurality of LED lamp pearls 7 on control circuit board 1, LED lamp pearl 7 arranges at least two kinds of colors, and the LED lamp pearl 7 of different colours is intervally arranged, be equipped with reflectance coating 2 between control circuit board 1 and LED lamp pearl 7, be provided with diffuser plate 3 above LED lamp pearl 7, be provided with translucent light guiding film 4 on diffuser plate 3, LED lamp pearl 7 is symmetrically distributed in the two ends of diffuser plate 3.LED lamp pearl 7 adopts square straight cutting lamp pearl.
The control circuit board of the present embodiment has only been installed 6 LED lamp pearls, the position of LED lamp pearl is symmetrically distributed in the circuit board two ends, when installing, LED lamp pearl need form head to head to install, being arranged on all LED lamps on 1 control circuit board 90-degree bent be adjacent to control circuit board 1 to the inside, form the effect of light correlation, like this in order to light is focused on diffuser plate 3.
Six LED lamp pearls adopt two kinds of colors simultaneously, such as red and green, mode of connection is common anode or common cathode, the lamp pearl of two kinds of colors is intervally arranged, if by this plate L1, L3, L4, L6 installs red square LED lamp pearl, L2, L5 installs the green LED lamp pearl, by peripheral control circuit board 1 control circuit signal, work as L1, L3, L4, tetra-lamp pearls of L6 are luminous separately is red, if L2, L5 is luminous separately is green, if the two is simultaneously luminous is yellow, reach more colour switching if want, only control circuit need be changed, install red simultaneously, green, indigo plant is the lamp pearl of tri-kinds of colors of RGB, in needs, control three-color LED light by circuit bright open whether synchronously, can reach the effect of this LGP multiple color conversion, without changing light guiding film 4.
Translucent light guiding film 4 is selected the materials such as white PC or PE, and white can be by the light of any color; Be provided with removable image-text panel 5 above translucent light guiding film 4, image-text panel 5 is picture or words that the user need to show, this one deck is placed directly on translucent light guiding film 4, by the LED lamp pearl of control circuit board 1 luminous and after reflectance coating 2, diffuser plate 3, translucent light guiding film 4 as backlight, image-text panel 5 is illuminated, to reach picture or the word shown on this image-text panel 5.
Transparent acrylic 6, mainly play two effects, and the one, logical light, the 2nd, play fixation, this acrylic board thickness is determined as required, but for convenient fixing and needs attractive in appearance, this acrylic board can be processed into many shapes, such as top be oval, be below rectangle etc.
As Fig. 3, in the light source use procedure, the LED lamp pearl meeting evolution of heat, temperature after having grown service time in light source is very high, in order to be conducive to heat radiation, reflectance coating 2 is made to structure as shown in Figure 3, a slice rectangular reflection film is set below each LED lamp pearl, the size of reflectance coating is 10 times of sheet LED lamp pearl area, and LED lamp pearl is positioned at rectangular reflection Mo De center; Due to the luminous intensity of sheet LED lamp pearl and illumination range more than 95%, concentrate on himself 10 times with in interior scope, so being set like this, the light that substantially can effectively LED lamp pearl be sent upwards reflexes to light guiding film, and, due to the area that has reduced greatly reflectance coating, make LED more easily dispel the heat.
