Description
Technical field
The utility model relates to a kind of powerful searchlighting powder, particularly a kind of touch floodlight projector.
Background technology
Existing floodlight projector comprises the mechanical switch of shell, bulb, power supply and contact-carrying, controls the on-off of power supply by the action of control mechanical switch during use, makes bulb luminous or close; The shortcoming of this floodlight projector be the life-span of mechanical switch short, reliability is low.
Summary of the invention
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 bulb duty---switching or brightness.
Described touch floodlight projector is characterized in that the number of metal touch head is two.During use, the user touches two metals simultaneously with hand and touches for the first time, and touch control circuit changes the duty of a bulb, and bulb is switched between the low light level, high light, the different conditions of closing.
Described touch floodlight projector, it is characterized in that described touch control circuit comprises IC 1, low light level control circuit, closes circuit for lamp and touch signal circuit, the touch signal circuit touches an A by metal and B, resistance R 4, R5, R18, R19, R20, triode Q7, IC 1 are formed, and wherein a metal touch A and B are connected to resistance R 19 two ends.As shown in Figure 2.
Described touch floodlight projector, the model that it is characterized in that described IC 1 is CD4017.
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 an 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, " IC1 " represents integrated circuit, and T1 is a transformer, and E is a battery, DP is a bulb, and A, B are that metal touches head.
The specific embodiment:
See illustrated in figures 1 and 2ly, described touch floodlight projector comprises shell 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 B exposes to outside the shell 1.
Its circuit theory diagrams as shown in Figure 2, described touch control circuit comprises IC 1, low light level control circuit, closes circuit for lamp and touch signal circuit, wherein to touch an A and B, resistance R 4, R5, R18, R19, R20, triode Q7, model by metal be that the IC 1 of CD4017 is formed to the touch signal circuit, and wherein a metal touch A and B are connected to resistance R 19 two ends.
The circuit of Fig. 2 comprises that rectifier charging circuit, bulb DP, triode Q4 and battery E constitute a discharge circuit.R3, R6, IC1 form charging and close circuit for lamp.Metal touches an A and B, R18, R19, R20, Q7, R4, R5, IC1 form the touch signal circuit.R11, R13, R12, R17, C5, C6, Q5, Q6, C2, R14, Q3 form low light level control circuit.IC1, C3 form the pass circuit for lamp.IC1, Q1, D6, R6, C4, R8, R9, ZD2, R10, Q2, R16 form the over circuit.
When connecting civil power AC220V, after transformer T1 step-down, send D1, D2, D3, D4 rectification, the one tunnel send battery E charging, and one the tunnel makes it luminous through R2 charging indication LED 2.When battery was full of, ZD1 was breakdown, and through R1, LED1 is luminous.
When staff touches a metal touch A and B simultaneously, the induced signal of human body makes Q7 be in conducting state, gives negative pulse of 14 pin of IC1, makes IC1 meter position, the 2nd pin output high level is delivered to many oscillating circuits of being made up of R11, R12, R13, R17, C5, C6, Q5, Q6.Provide positive supply to make its work starting of oscillation.Be coupled through the base stage of R14 by C7 to Q3.Make the Q3 conducting.Q4 just gets and conducts, and bulb is luminous owing to the cycle of conducting and the resonant frequency synchronised of multi-resonant oscillating circuit, thereby the purpose that reaches light modulation makes it be in the low light level.When staff touches metal when touching an A and B more simultaneously, the induced signal of human body makes Q7 be in conducting state to make IC1 meter position for negative pulse of 14 pin of IC1 once more, the 4th pin output high level.It is luminous that the base stage of delivering to Q3 through R21, D7, R14 makes Q3 conducting Q4 must conduct bulb, and be high light this moment.
When bulb is worked, Q4 conducting R16 ground connection, the Q1 conducting, voltage is given the power supply of Q base stage through R9,2D2, R10, the Q2 conducting make through R8 to C4 energising discharges over the ground through Q2 simultaneously, D6 oppositely makes current potential at the bottom of the 15 pin places of IC1, the IC1 attitude of remaining stationary.
When dropping to the voltage stabilizing value ZD2 that is lower than ZD2, ends cell voltage; Q2 base stage place low level is cut off; charging makes 15 pin place high potentials through 15 pin of D6 to IC1 simultaneously to C4 through the forward voltage of R8, and IC1 is reset, thereby the protection battery of turning off the light is not increased the service life by discharge too.
Touch metal for the third time simultaneously when touching an A and B when staff, will make IC1 calculate the 7th pin output high level simultaneously, be coupled to IC1 the 15th pin preset end, force the IC1 zero clearing that resets, thereby turn off the light through C3.
Thereby do not need the mechanicalness 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
