The new generation of LED dimmable lamps started to sell on June 5, 2010.Hong Kong Chia Tai Technology Development Co., LTD took 5 months research and continuous improvement to solve the high temperature caused flicking and narrow scope problem.

Optional dimming model are as follows:

1.         GU10 3X2W LED spotlights

2.        GU10 3x3W led spot light

3.        GU10 3x2W led spot light

4.         GU10 3x1W led spot light

5.         GU10 led spot bulb 3X1W 30°

6.        GU10 spotlight led lights C3W

When you try your efforts to dress up you living room as well as the bedroom, it’s so important that it all your taste and lifestyle will give your every guest a good impression, the design of the bed is a deep art, you may choose a perfect lamp around you may need a cool design, please pay attention to GosoLED’s new dimming series.

In order to achieve aesthetic value and saving energy, we need to use dimming to change the illumination light intensity, Gosoled Lighting developed newly stable LED Dimmable Lamp, suitable for a variety of conventional dimmers (TRIAC, adjustable Front edge and trailing edge dimmer,). Smooth and stable dimming performance can be suit for different occasion as easy as the incandescent lamp.

A. Dimming Advantages:

1.      Support for the majority of available dimmers (e.g. TRIAC, transistor) ;

2.      In the dimming range, all the input LED current ripple and current are constant ,the voltage is stable, no flicker, we can greatly extend the life of our lamp. Dimming range is between 5% -100% (Due to working current calculation), PFC0.8 (full-bright state test);

3.      When external voltage fluctuation, LED power supply current is constant, the brightness keep the same.

4.      Input Voltage: 110Vac/230Vac

5.      Better efficiency thanks to valley detection

6.      Adjustable natural dimming curve integrated

7.      Natural dimming via a built-in logarithmic curve

B. Dimming technology explains:

Through the gray sub-series and non-linear dimming, Pulse width modulation presents a technique to safely dim an LED from 5% to 100% of full luminous flux. When the LED is pulsed with current while varying the duty cycle of the current waveform, the LED rapidly transitions between on and off. The relative times spent give the impression of being dimmed. Dimming design is based on technology of frequency and peak current modulation, The use of on-time mode and frequency mode to control the LED brightness， not cause changes in the wavelength, which provides even and stable dimming, To create an ideal lighting environment.

C. Application:

The LED dimmable lamps are widely used in residential, hotels, restaurants, KTV, meeting room with existed SCR dimmers. It can be directly applied to the original SCR dimmer. Therefore, it save re-wiring, re-installation new controllers and cost of renovation, etc. So it is very economic and environmental protection.

D. Lifetime testing:

Multiple tests and set-ups were used to detect all possible failure modes in several use cases: continuous-on, on/off switching cycle and various combinations.

    Over 50,000 hours lifetime at 60℃

    Over 25,000 hours lifetime at 115℃

    Over 10,000 hours at 125℃

    Over 3,000 hours at 150℃

The test is part of an Gosoled Lighting project dedicated to assessing the actual lifetime of its latest LED drivers.
