Abstract
The utility model discloses a light emitting controlling device which comprises an IC (integrated circuit). Two output pins of the IC are respectively connected with a group of triodes; an output end is formed by the collecting electrode of the last triode in each group; one control pin of the IC is connected with a pressure-actuated switch which is used for controlling the work state of the two groups of triodes; and the power input pin of the IC is connected with a power supply through a voltage stabilizing circuit. The automatically controlled internal or external IC in the original bicolor LED is eliminated, and a simple anode-cathode circuit control device is designed. The change of the anode and the cathode of an output power supply is controlled by a manually pressed key so that the bicolor LED emits randomly the light in needed color. In addition, the emitting controlling can normally adapt to the working voltage of very wide range from 3V to 240V, and the original defects that bicolor LED is automatically controlled through the IC to emit light, the colors of light emitted by the bicolor LED are disorderly and can not be manually controlled and the cost is high are overcome.
Description
Technical field
The utility model relates to emission control device, be specifically related to a kind of be used for control use LED (light-emitting diode) to be the ornamental light fixture of light source or the device and the lamp string of lamp string.
Background technology
Ornamental light fixture of LED or lamp string, owing to have characteristics such as abundant light coloring, super low energy consumption, under the more and more nervous situation of the energy in the world today, ornamental light fixture of LED or lamp string have been obtained in daily life very widely and have been used.Ornamental light fixture of present LED or lamp string through fast development in recent years, from original simple structure, expensive, progressively develop to the multi-functional direction that reduces cost.In order to control the illumination effect of double color luminotron, existing technology all is the color of being sent through IC Automatic Control dual-colored LED, and the glow color that causes is disorderly and unsystematic, can't Artificial Control, defect of high cost.
The utility model content
The purpose of the utility model is, to the above-mentioned defective of prior art a kind of circuit control device of special use is provided, and makes dual-colored LED pass through the control of this control device, realizes that dual-colored LED can change the effect of glow color at any time arbitrarily.
A kind of emission control device is provided; Comprise an integrated IC; Two output pins among the said integrated IC are connected to one group of triode respectively; The collector electrode of last triode of every group of triode constitutes an output, the control pin of said integrated IC be connected to one be used to control said two groups of triode operating states pressing switch, the power supply input pin of integrated IC is connected with power supply through voltage stabilizing circuit.
In above-mentioned emission control device; Said one group of triode has three; The connected mode of three triodes is following: the base stage of first triode of each group triode is connected with the output pin of said integrated IC; Its emitter is connected with the base stage of the 3rd triode of another group, and the collector electrode of second and the 3rd three utmost point of same group of triode is connected to form output.
A kind of lamp string that adopts above-mentioned emission control device is provided again; Constitute by a plurality of double color luminotron serial connections; Input at said lamp string is connected to said emission control device, and two outputs of said emission control device are connected with two input control ends of said lamp string respectively.
The utility model utilizes the characteristic of the unidirectional conducting of LED; The IC of the internal or external automatic control in the former dual-colored LED is removed; Design a simple positive and negative electrode circuit control device, change by key control out-put supply both positive and negative polarity, reach dual-colored LED and send own required color arbitrarily through manual; The working voltage that can adapt to non-constant width simultaneously; Can normally use from 3V-240V, thus changed former in IC Automatic Control color that dual-colored LED is sent, and the glow color that causes is disorderly and unsystematic, can't Artificial Control, defect of high cost.
