Abstract

The utility model relates to a touch floodlight projector with the advantages of long service life and high reliability. The touch floodlight projector comprises an outer shell, a bulb, a power supply and a touch control circuit. The utility model is characterized in that one metal touch point of the touch control circuit is exposed out of the outer shell. When the touch floodlight projector is used, the working state such as power turn-on, power-down, brightness change or flash of the bulb can be changed according to the change of signals received from the metal touch point by the touch control circuit when users touch the metal touch point exposed out of the outer shell by hand.

Description

Touch floodlight projector

Technical field:

The utility model relates to a kind of electric consumption on lighting tube, floodlight projector, particularly a kind of touch floodlight projector.

Background technology:

Existing traditional floodlight projector comprises the mechanical switch of shell, bulb, power supply and contact-carrying, controls the on-off of power supply during use by the action of control mechanical switch, makes bulb luminous or close; The shortcoming of this floodlight projector be the life-span of mechanical switch short, reliability is low.

The purpose of this utility model is the short problem of switch life that exists in the existing floodlight projector in order to solve, and the touch that a kind of switch life is long, reliability is high floodlight projector is provided.

Technical scheme:

The purpose of this utility model is achieved in that a kind of touch floodlight projector, comprises shell, bulb, power supply and touch control circuit, it is characterized in that the metal touch head of described touch control circuit exposes to shell.During use, touch head as long as the user touches the metal that exposes to shell with hand, touch control circuit promptly touches a variation of the signal of telecommunication that receives according to it from metal and changes the switching of bulb duty, brightness variation or flash of light.

Described touch floodlight projector, the number that it is characterized in that metal touch head is one, and during use, the user touches metal with hand and touches for the first time, touch control circuit changes the duty of a bulb, and bulb is switched between the low light level, high light or flash of light, the different conditions of closing.Described touch floodlight projector, it is characterized in that described touch control circuit comprises IC 1, triode Q1, the low light level, high light, flash of light, pass lamp control circuit IC2 and touch signal circuit, the touch signal circuit is made up of a metal touch A, resistance R 4, R5, R6, R7, R8, capacitor C 1, C2, C3, diode D6, D7, D8, triode Q1, IC 1, and wherein metal touches the common contact that an A is connected R5, R6, D6 and IC16 pin.As Fig. 2

Beneficial effect:

Owing to adopted technical scheme described in the utility model, touch head with metal and replaced mechanical switch, bulb has been realized contactless control, prolonged its service life, and the reliability height, simple in structure.

Description of drawings:

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the outside drawing of one of them embodiment of touch floodlight projector described in the utility model.

Fig. 2 is the circuit theory diagrams of Fig. 1 embodiment.

" R " expression resistance among the figure, the numeral sequence number of back, " Q " represents triode, the numeral sequence number of back, " C " represents electric capacity, the numeral sequence number of back, " D " represents diode, the numeral sequence number of back, and " ZD " represents Zener diode, the numeral sequence number of back, " IC " represents integrated circuit, the numeral sequence number of back, T1 is a transformer, E is a battery, and DP is a bulb, and A is that metal touches head.

The specific embodiment:

See illustrated in figures 1 and 2ly, described touch floodlight projector comprises shell Fig. 1, bulb DP (Fig. 2), power supply E (Fig. 2) and touch control circuit (Fig. 2), and shell 1 is provided with handle 11, and wherein the metal among Fig. 1 touches an A and exposes to shell 1 place.

Its circuit theory diagrams as shown in Figure 2, described touch control circuit comprises IC 1, the low light level, high light, flash of light, pass lamp control circuit IC2 and touch signal circuit, wherein the touch signal circuit is made up of a metal touch A, resistance R 4, R5, R6, R7, capacitor C 1, C2, C3, C4, C5, diode D6, D7, D8, D9, triode Q1, Q2, Q3, IC 1, IC2, and wherein metal touches the common contact that an A is connected resistance R 5, R6, diode D6 and IC16 pin.

The circuit of Fig. 2 comprises rectifier charging circuit, and bulb DP, IC 1, IC2 and battery E constitute a discharge circuit.R3, IC2 form charging and close circuit for lamp.Metal touches an A, D6, R4, R5, R6, R7, R8, Q1, IC1 composition touch signal control circuit.IC2, R10, R11, Q2, Q3 form the low light level, high light, flash of light, pass lamp control circuit.

When connecting alternating current AC220V, after transformer T1 step-down, send D1, D2, D3, D4 rectification, the one tunnel through D5 to battery E charging, the one tunnel makes it luminous through R1 charging indication LED 1.When battery was full of, ZD1 was breakdown, made LED2 luminous through R2, was full of the electricity indication as battery.

Touch an A when staff touches metal, the induced signal of human body makes 10 pin of IC1 that a positive pulse be arranged, and through the base stage of R7 to Q1, makes the Q1 conducting.7 pin that trigger IC2 make 5 pin export resonances by the very fast level that changes of cycle, high level, resonance by level and low level that the cycle changes more slowly, make Q2, Q3 conducting synchronously or only carry by the variation of above-mentioned level.Thereby make bulb DP realize the low light level, high light, flash of light and extinguish.

Thereby do not need the mechanical switch course of work in the process of turning off the light of turning on light, easy to use, can not cause because of mechanical performance is bad can not switch lamp puzzlement, more can frequently not damage switch because of using, and used single touch point, and cooperate more rational electronic circuit to make more convenient operation, reliability is higher, structure is simpler, and fault rate is lower.
