EL Lamp Driver Using HV832MG
An EL lamp is a solid state, low power, uniform area light source. Because of its thin pro ¬le (as thin as 0. 3 mm) and the fact that it can be built into almost any size and shape, EL lamps are an ideal way to provide back-lighting for LCD displays, membrane keypads and a variety of other applications. Electroluminescent (EL) lamps offer signific
Pathway Lighting with LEDs
Simple pathway lighting that would provide illumination for the path at night. Extension for the Solar garden Light. The torroid is bifilar wound. The Torr.
Telephone control automatic lighting circuit 1
The diagram shows telephone control automatic lighting circuit. At night, when telephone rings or master takes up telephone transmitter dialing, the light can lighten; when telephone ringer stopped (no one listen) or on-hook, it can delay 10~40s, then the light can die out itself. Moreover, this circuit also set a light triggering button. The ligh
Solar Lifeforce LDR volume pedal circuit
Here is a simplified schematic for the Solar Lifeforce. Basically I have removed the expression/CV out stuff, removed the toggle for the buffer so the buffer is always on, and made it as simple as possible. It could maybe do with some small value caps between both R5 and ground and R9 and ground, but they aren`t essential. The LDR is a pretty
Design a esthetic and energy-conserving acousto-optic controlled lighting lamp of corridor
The optically-controlled circuit has essential function in urban street lamps or corridors are lighted, adopt the optically-controlled circuit, can open and shut off the lighting lamp automatically according to power of the light, make sure nobody automaticallies control, can lighten workers` labor intensity, valid power saving. But optically-cont
Reuse Old Mobile Phone Battery for LED lighting
Normally mobile batteries have a lifespan of 2-5 years under normal usage. But then we have to replace them. Nowadays there are cheap replacement batteries which cost no more than 1$. But these low cost batteries run only 6-12 months. What to do with the used batteries, which can`t be reused in mobiles Well, easy solution is to use the batteries i

555 alarm doorbell and lighting controller circuit
As the figure 15-24 shows, the controller circuit is composed of the switch type Hall integrated circuit DN838 and the astable multivibrator (composed of the 555), this circuit can be used in wide range of applications such as the automatic door opening, automatic delay alarm, automatically turns off the lights and also it can be used as the doorbell. The a..
LED lighting circuit and liquid crystal display device
The present invention discloses an LED lighting circuit that generates a power supply voltage required to light an LED by boosting a power supply voltage. The LED lighting circuit includes a power supply circuit that is formed integrally with the LED lighting circuit and supplies the power supply voltage. The LED lighting circuit further includes a feedback circuit that detects an LED current...
Handy Pen Torch circuit
This easy to construct Handy pen torch electronic circuit and low component count, uses two power white LEDs for lighting. Low volt (4. 8V dc) supply available from the built in rechargeable Ni-Cd battery pack is first converted into two channel (independent) constant current sources by two pieces of the renowned precision adjustable shunt regul
Sensors for lighting controls are either photoelectric sensing or presence detectors. Photoelectric sensors are normally set to switch lighting on at dusk and off at dawn. Adjustments can be made to change response to higher or lower levels. Built-in time delay helps to eliminate nuisance switching in response to sources other than natural ambient

Model Theatre Lighting Dimmer
This circuit is the basis for the dimmers in a model theatre lighting system which uses touch globes as the light source. The circuit is based around a 555 timer, driving a Triac. All dimmers share the one power supply and zero-crossing detector. As it will only work if there is a common AC/DC return path, it has a simple DC supply circuit consist
Automotive Emc Considerations For Switching Regulator Led Lighting Applications Using Zxld1362
Lighting Consultancy and Supply
The success or failure of your lighting upgrade efforts rides on the quality of your parts and the quality of your work. It matters how carefully you route wires to avoid chafing insulation. It matters how well you solder connections (crimps and sloppy or `cold` solder joints corrode and die). It matters how well you shield added wiring from road
Automatic Light Controller Using 7806
Voltage regulator ICs (78xx series) provide a steady output voltage, as against a widely fluctuating input supply, when the common terminal is grounded. Any voltage about zero volt (ground) connected in the common terminal is added to the output voltage. That means the increase in the common terminal voltage is reflected at the output. On the othe

DMX Lighting System
The momentary switch used was rated for 10A for safty. If the switch was rated for too small a current, the instantaneous current for the first millisecond would fuse the switch contacts together. To achieve objective 3, some sort of switch that can vary current must be used. The posibilities are potentiometer, pulse width modulation,

Making an Ikea Mood Lamp Beyond All Repair
Since I first got my Arduino and some RGB LEDs I`d wanted to build myself a mood lamp with some funky features (note that I used the word funky and not useful). Well, I`ve finally done it, and here is the blog post describing how. For this project I used the Ikea GrG¶nG¶, which was £4. 99 when I bought it. It quite a nice matt glass finish, which
LED Lighting For Dual-Filament Lamps
Before we describe how it`s done, note that we recommend that the result be checked as having sufficient brightness for a stop & tail-light application. That`s because the light output may be inadequate, depending on the tail-light lens and reflector assembly - so use any modified lamps with discretion! As shown, an additional diode (D1) and resis
