Abstract

The utility model relates to an electronic lamp which is used as a lighting key button or a miniature lighting source when power is off, comprising a casing, a spring piece in the casing, a reed switch and a light emitting diode, which is characterized in that the light emitting diode is provided with more than one lamp wicks, the output foot of the light emitting diode is connected with a printed circuit board, an integrated block circuit is welded on the printed circuit board; the casing of the electronic lamp is formed by connection of two elastic plastic cases with the same shape, when the fingers press the central part of the elastic casing of the electronic lamp, the circuit power is switched on, the integrated block in turn provides the light emitting diode with a square wave with a frequency of more or less thirty Hz, at that time, if the light emitting diode is at a stationary state, the light emitting diode can give off flashing purple light, if the light emitting diode is sloshed, the phenomenon that the color of the light changes from single purple to two colors of red and blue can be observed. The utility model has the advantages that the electronic lamp can give off flashing colorful lighting light, because the low frequency square wave voltage power supply is adopted, the power consumption is small, the life is long and the energy is saved.

Description

Velocitron

Technical field

The utility model relates to a kind of velocitron.

Background technology

Velocitron is buckled as illuminating key or the use of the micro lighting light source when having a power failure usually, existing velocitron is mainly by monochromation illumination, it as China Patent No. 00240412 illuminating key button, its lighting source only is common small lamp bulb, though it can throw light on, because small lamp bulb directly adopts direct current supply, not only power consumption is big, the life-span short, and issued light only is common white light also, and tone is single; In recent years because the develop rapidly of led technology, because the light emitting diode power consumption is little, life-span is long, the brightness height, all present the trend that substitutes the general lighting lamp with light emitting diode in a lot of fields, though design the illuminating key button that substitutes small lamp bulb with light emitting diode existing scientific worker aspect the illuminating key button, it as China Patent No. 99241197 illuminating key button, it is directly to be connected on diode lights on the button cell, bright dark by microswitch control diode lights, its shortcoming is that used diode lights is common light emitting diode, and color still is single, and its power supply or direct current, power consumption are still bigger.

Summary of the invention

Technical problem to be solved in the utility model is a kind of velocitron of design, and it not only uses led lighting, can also make light emitting diode launch the color lighting light of flicker, and power consumption is very little.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of velocitron, it comprises spring leaf, battery, spring leaf switch and light emitting diode in shell and the shell, it is characterized in that described light emitting diode is a light emitting diode with an above wick, its output pin is connected with printed circuit board (PCB), is welded with ic circuit on the printed circuit board (PCB); A described above wick light emitting diode is a light emitting diode with two colored lights cores; Described integrated package is that model is the special IC of MT-3149, and it is the low-frequency square-wave that light emitting diode provides a human eye to discern, and makes two colored lights cores of light emitting diode alternately glimmer luminous; Described shell is to be formed by connecting by two whippy plastic casings, by pushing the shell central part of snap switch position, just can control the duty of light emitting diode.

Compared with prior art, advantage of the present utility model is that this velocitron can send the color lighting light of flicker, owing to adopt the low-frequency square-wave power voltage supply, power consumption is little, and the life-span is long, so energy savings.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, velocitron comprises shell 1, anodal spring leaf 2 in the shell 1, button cell 3, negative spring sheet switch 4, light emitting diode 6, anodal spring leaf 2 links to each other with the positive pole of button cell 3, negative spring sheet 4 links to each other with the negative pole of button cell 3, as shown in Figure 2, the break-make of light emitting diode 6 is to be that snap switch 4 positions are controlled by the whippy shell central part of finger presses, described light emitting diode 6 is the light emitting diodes with red blue two colored lights cores, two colored lights cores are connected into common anode construction, it has three leading foots, wherein two pins are respectively red, the negative electrode pin of blue two colored lights cores, another one is red, the public anode pin of blue two colored lights cores, they are welded on three pads of printed circuit board (PCB) 5, the circuit diagram of velocitron as shown in Figure 3, be welded with ic circuit on the printed circuit board (PCB) 5, it is one one kinds of special-purpose ic circuits of being made up of oscillator etc., the model of this ic circuit is MT-3149, in order to save the space, adopt the soft packing forms of little printed board, it has 7 leading foots, wherein the VDD pin is by welding positive source reed 2 in the circuit board and 3 anodal linking to each other of button cell, the VSS pin connects anode reed switch 4, OSC1, be connected to a resistance R 1 between the OSC2 bipod, R1 is the outer meeting resistance that ic circuit produces the required oscillator of passage of scintillation light, its resistance size decision square wave concussion frequency, the L1 pin links to each other with the negative electrode pin of red wick by resistance R 2, the L5 pin directly links to each other with the negative electrode pin of blue wick, the common anode pin of light emitting diode 6 two colored lights cores links to each other with positive source, and the ON/OFF pin links to each other with a rectangle copper pool of printed circuit board (PCB).

The concrete course of work is: when the elastic housing central part of finger presses velocitron, power cathode reed 4 just contacts with rectangle copper pool on the printed circuit board (PCB) 5, circuit power is connected, the L1 of integrated package MT-3149, L5 castor stream is square wave about 30 hertz for light emitting diode 6 provides a frequency, this moment is if light emitting diode 6 remains static, it just sends the purple light of flicker, if begin to rock light emitting diode 6, the color that then can see light changes to red blue dichromatism from single purple, and this is due to the temporary effect of human eye vision.
