Description

The polychrome bulb

The utility model relates to a kind of polychrome bulb, belongs to decorating using colored lamp.

Along with improving constantly of people's living standard, daily life becomes increasingly abundant colorful, demand to light fixture also is miscellaneous, from white to the colour, from the colour to the polychrome, though but the bulb on the market is coloured, but all be single color basically, and dull coloring, therefore press for a kind of polychrome bulb that can send multicolour, for this reason, people are through long-term endeavour, various polychrome bulbs have been developed, as the patent No. is ZL97200939.6, and name is called disclosed a kind of polychrome bulb in the utility model patent of " colorful Color-changing lamp ", it is characterized in that being provided with in the colorful Color-changing lamp three miniature bulbs (pearl), the light that three miniature bulbs send is respectively a kind of color in the three primary colors, three lampets soak an annulus and distribute, and respectively are 120 degree at interval, and miniature bulb is fixed on the pedestal of bulb, three miniature bulbs respectively have an end to be connected to the common end of pedestal, and its other end is connected respectively to each distribution terminal.Brightness separately by three miniature bulbs of peripheral control unit control produces various different colors, but because only be provided with three miniature bulbs in the Color-changing lamp, self be difficult to present multiple pattern, lack aesthetic property, and also need to be equipped with nonshared control unit in addition, give and to use and installation has brought inconvenience, also be unfavorable for producing on a large scale.

The purpose of this utility model is to the not enough a kind of nonshared control unit that need not to join in addition, easy to use and polychrome bulb that can present multiple pattern of providing of above-mentioned prior art is provided.

For realizing the purpose of this utility model, technical solution of the present utility model is as follows: the polychrome bulb comprises transparent lampshade and is arranged on the lamp holder that is used to install bulb that monochromatic illuminator reaches and lampshade fuses in the lampshade, it is characterized in that: described illuminator is arranged on the circuit board by required pattern grouping, and control by control circuit, control circuit is made up of rectification circuit, pulse generating circuit, pulsqe distributor and drive circuit, pulse generating circuit, pulse distributor and drive circuit connect successively, and rectification circuit provides power supply for it.

Adopt the polychrome bulb of above technical scheme, illuminator does not coexist according to brightness ratio between the three primary colors under the control of control circuit, can send various colors, drives if illuminator arranged and divide into groups by required pattern grouping, then can present many picture groups case.

The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.

Accompanying drawing 1 is the utility model example structure schematic diagram;

Accompanying drawing 2 is arranged schematic diagram for the present embodiment illuminator;

Accompanying drawing 3 is a present embodiment control circuit schematic diagram.

As shown in Figure 1, lampshade 3 is a flare housing of being made by glass, the lamp holder 5 that lampshade 3 is used to install bulb fuses, circuit board 2 is circular printed panel, be fixedly set in the lampshade 3, illuminator 1 is pressed required arranged in patterns on circuit board 2, illuminator 1 is by red, green, blue three look high brightness LEDs are formed, in the present embodiment circuit board 2 is divided into 9 sector regions, three primary colors illuminator 1 is fixed in 9 sector regions successively, each zone evenly is provided with 30 light emitting diodes and forms one group, totally three groups of homochromy illuminator L1, L2, L3 (referring to Fig. 2), control circuit is by rectification circuit 4A, pulse generating circuit 4B, pulse distributor 4C, and drive circuit 4D forms, pulse generating circuit 4B is the oscillating circuit that core and peripheral cell are formed by 555 time base circuit IC1, pulse distributor 4C is that CD4017 and diode D1-D13 form by integrated IC2, the output Q0 of CD4017, Q1, Q2 is respectively through diode D1, D2, D3 is connected to the input of drive circuit 4D, the Q7 output is connected to reset terminal RES through diode D12, Q3 is connected to the mid point of change-over switch K, two other contact A of change-over switch K, B is connected to diode D1 negative pole and the reset terminal RES that Q0 holds through diode D4 and D13 respectively, output Q4 is connected to diode D2 negative pole through diode D6, output Q5 divide two the tunnel, one the tunnel is connected with diode D1 negative pole through diode D8, another road two utmost point D9 are connected with diode D3 negative pole, output Q6 also divide two the tunnel, one the tunnel through diode D10, the D5 series arm is connected to diode D2 negative pole, and another road is through diode D11, the D7 series arm is connected to diode D3 negative pole; Drive circuit 4D is made of three groups of identical circuit of structure, every group is made of base resistance R3, R4, R5, collector load resistor R6, R7, R8 and amplifying triode BG1, BG2, BG3 and controllable silicon SCR 1, SCR2, SCR3 respectively, the emitter stage of amplifying triode is connected with the controllable silicon trigger electrode, and controllable silicon SCR 1, SCR2, SCR3 are connected on respectively in the electric power loop of three groups of light emitting diode L1, L2, L3.

The circuit working principle is as follows: the pulse of counting circuit IC2 (CD4017) paired pulses generation circuit 4B is counted, when change-over switch K is in contact position, its output Q0, Q1, Q2 export high level respectively successively in turn, drive triode BG1, BG2, BG3 conducting and trigger controllable silicon SCR 1, SCR2, SCR3 and take turns conducting, make three groups of light emitting diode L1, L2, L3 luminous in turn; When change-over switch K is in the contact A position, three groups of light emitting diode L1, L2, L3 take turns luminous after, transfer to two groups luminous in turn together, enriched the variation of pattern and color more.
