Gelighting dimmer compatibility pdf download problem

The load effect is easily produced in this case, MOS based on the level of a binary digital code. The current and the driving current accuracy will degrade. To avoid this of power MOS can be controlled by the digital number.

Each step obtain a low gm and high Ro. The digital code can linearly decide the diving current with step-by-step. The Rl and R2 are used to provide the 6 reference current. Due to process deviation, the on-chip resistor The load of current source is R2, let R;; »R2, to avoid possibly produces large error. In this case, the driving current can be adjusted by the external resistor Rs to meet the the load effect and increase current control accuracy.

The high voltage M2 is split is split to 2n small MOS in parallel. So the connected to power MOS. CkX -L..

The switch control pins Cl to power MOS respectively. When binary code is used for computer compatible. Hence the system driving power is increased. The prototyping chip is designed with TSMC 0. The power MOS used 60V decoder is designed as for the digital interface. Table 2 list the component, and the other control circuit used 5V process, to truth table of the n-to-2n decoder.

The input A3 to AO, and the keep better cost-efficiency. According to high-power street lamp dimming, so the digital control with the truth table, one can attain the control signal for each step current adjustment is enough in practical system. The switch. After logic reduction, we can obtain the logic driving current as input is from to with binary code equations for each MOS control switch as using Spice simulations.

The current step can be fixed with ffafi x The last stage is high-power driving for LED. The mirroring LED in linearity. The LED driving current chip layout is drawn in Fig. We select various input signals using a 4-bit switch, and measure a b the output diving current with one current meter.

The measured results are listed in Table 2. Figure 5 draws the linear curve of the current vs the digital control step. The output current can be linearity with the input binary code. Figure 6 shows the demonstrated broad with 8x5W LED under various diving c d current. In order to sample the photos clearly, the dark optical filter is added in the camera head.

The Results are shown the right side of Fig. The input power is dissipated by the internal control step is about 45 degree. The PWM control chip f'f':. Our driving power is about 60 12 times of [8], as using small chip area that is close to [23]. Lun, K. Loo, S. Tan, Y. Lai, and C. Tse, lighting system. However, its dimming [10] J. Vifia, D. Estimated Time: Depends on personal level experience and ability to work with tools. Precaution: Identify the light circuit, turn it OFF and Tag it with a Note before working with the dimmer switch wiring.

Materials: Make sure the replacement dimmer switch has the same amperage and voltage rating as the original switch, and is fully compatible with the electrical circuit, the light fixture and the type of light bulbs being used. The dimmer switch must be rated for the amount of watts that will be controlled. How to Wire a Switch. Wiring a Dimmer Switch. Fully explained 3 way dimmer switch wiring diagram will take the mystery out of wiring a 3-way dimmer switch. Home Lighting Learn about how to install and wire home light fixtures.

Get a Quick Reply! Ask the Electrician. Helping You to Wire It Right! Use standard dimmers on line voltage and low voltage dimmers for 12V and 24V applications. The total wattage of all lamps is less than or equal to the maximum wattage rating on the dimmer switch. If you're dimming one bulb, this probably isn't a problem. But for track lighting or recessed can lights where more than one bulb is controlled at the same time, you need to add up the total watts for all lights. For example, a Watt incandescent dimmer can support up to eight 75 Watt bulbs.

Unfortunately that is not the case and the same is true of dimmable fluorescent bulbs paired with fluorescent dimmers. The easiest way to ensure that your light bulbs and dimmer controls are compatible is to check the lamp's manufacturer spec sheet or dimmer compatibility sheet.

At Bulbs. If you have a dimmer switch already and are looking for new bulbs, check to see that the dimmer is listed on the PDF prior to purchasing the bulbs. If you already have light bulbs and are looking for a dimmer switch, find the product page for the bulbs and check the PDF for a list of compatible dimmers to choose from. The specific dimmer compatibility information will always be with the bulbs rather than with the dimmer.

The compatibility sheet will often list common dimmers or whole lines of dimmers by the manufacturer part number or catalog code. If you need confirmation of partial or full compatibility, contact the manufacturer of your bulbs to verify. Whether you're trying to dim under cabinet lighting in your kitchen or overhead lighting in your office building, the symptoms of having incompatible devices paired are similar. The most common complaints involve the light bulb not dimming to expected low levels, blinking or flickering at certain thresholds, humming, or buzzing.

Other dimmer compatibility issues include:. Drop out: the light cuts out suddenly prior to reaching the bottom of the dimming range. Pop on: the lights brighten more suddenly than expected at a certain point when dimming towards full brightness.

Unresponsive: lights remain at a constant brightness for some or all of the dimming scale, not responding to adjustments made at the dimmer. If you experience any of these symptoms, turn off the lights and troubleshoot because chances are there's nothing wrong with the dimmer or the lights, the two just aren't meant to be friends.

First, make sure that your lights are dimmable.
