Abstract

A remote-control LED lamp relates to a lamp which takes an LED as the light source and is turned on/off through a remote controller. The lamp comprises a light source power supply, a micropower regulated power supply, a remote-control receiving module, a dim light delay circuit, a bright light delay and rapid discharge circuit, a dim light control circuit, a bright light control circuit, a over-current protection circuit and an LED light source circuit. The lamp is characterized in that a remote-control receiving module power supply is independent from the light source power supply, and adopts the micropower regulated power supply, thereby causing small static power consumption; the dim light control circuit is independent from the bright light control circuit, and is connected with the dim light delay circuit, a bright light delay circuit and the over-current protection circuit for the joint control on the LED light source circuit, so that the light emitted by the lamp can gradually become brighter from a dim light after being turned on, and fades into dim light before being turned off, which not only avoids the high-current impact on the LED to prolong the service life of the LED, but also reduces irritation on the eyes of users; and the dim light is emitted when the over-current protection circuit works, and after the current returns to normal, bright light is emitted, so that the use becomes more convenient. Therefore, the lamp provided by the utility model is particularly suitable to be used in places such as families, hotels, offices and the like.

Embodiment

Consult Fig. 2, the utility model be described in further detail:

When energising, 220 volts of civil powers are through little power consumption stabilized voltage power supply: the D1 rectification, the step-down of R2 current limliting, (small-power silicon triode emitter junction replaces the ordinary silicon voltage stabilizing didoe, and small-power silicon triode emitter junction only need consume electric current below tens microamperes and just can have good pressure stabilization function in the reverse breakdown state in the Q1 voltage stabilizing, the ordinary silicon voltage stabilizing didoe is worked under so little electric current, it is very poor that its voltage regulation performance becomes, even lose pressure stabilization function, so the voltage stabilizing power consumption is little.), C2 filtering is for IC1 remote control receiver module (the infrared or wireless receiving module of little power consumption) provides power supply; T1, T2 are that the MCR100-6 controllable silicon only needs tens microamperes of electric currents just can reliably trigger, and have only tens milliwatts so the utility model quiescent dissipation is very low, and power savings is remarkable.

Press infrared after the energising or the wireless launcher key of turning on light, at this moment to receive signal 3 pin be high level to the IC1 remote control receiver module of remote control LED lamp, low light level delay circuit C5 is charged to the T1 conducting after the R8 current limliting of low light level control circuit T1 silicon controlled trigger voltage soon through the R7 charging, at this moment 220 volts of civil powers are through light source power R1, C1, D1, D2, D3, add to circuit of light sources current-limiting resistance R3 behind the D4 step-down rectifier, several high-brightness LEDs of LED1 to LEDN1, R9, T1 forms the loop, because of the big remote control LED lamp of R9 resistance is sent out the low light level, C3 is a LED lamp string voltage stabilizing shunt capacitance, not charging of capacitor C 1 when energising, its both end voltage is 0, but this moment, all voltage makes LED avoid the instantaneous pressure damage through the C3 bypass, the pulsating voltage of R2 of flowing through after the C1 charging adds to LED lamp string after C3 filtering, the LED lamp string is pressed more steady, and R4 is the C3 discharge resistance; The high light delay circuit is because of being added with voltage stabilizing didoe D6 simultaneously, so C4 charges to D6 voltage stabilizing value with after current-limiting resistance R10 triggers controllable silicon T2 conducting through R5, at this moment short circuit current limitation resistance R 9 makes by the LED electric current and increases a high light, elder generation's low light level high light again makes LED avoid heavy current impact to prolong its useful life, reduce the stimulation to eye again: current foldback circuit current sense resistor R11 goes up voltage when overtension or other reason make the remote control LED lamp current excessive increases and makes the Q3 conducting through current-limiting resistance R12, at this moment the Q2 base stage is that low level conducting T2 loses trigger voltage and ends, get back to the low light level state of sending out, the normal back of remote control LED lamp current Q3 again sends out high light by R5 to C4 charging back T2 conducting by Q2, uses more convenient; When pressing infrared or wireless launcher when turning off the light key, it is low level that the remote control receiver module receives signal IC1:3 pin, at this moment quick discharging circuit triode Q2 is through current-limiting resistance R6 conducting, T2 ends with C4 short circuit repid discharge, this moment, low light level delay circuit C5 discharge was slower, and the both first low light level is closed the stimulation of minimizing to eye again; So the utility model quiescent dissipation is little, simple in structure, cost is low, easy to use, the life-span is long, and is little to people's eye irritation; The use in places such as suitable especially family, hotel, office.
