Tianjin: How to find the balance point between the main LED lighting and the high price

Tianjin Haiyu lighting person in charge said: Overall, main LED lighting industry has an advantage, and the prices it is still not enough on its increasingly high demand, customers not only value is the energy saving effect, but the price is also attached considerable importance their principles out the least money, buy the most affordable energy-efficient products, but this is often in conflict. For example: the same two LED manufacturers A and B, Company A imported chip...Continue reading

The IMC photo electric MCOB package, LED high bay lamps since listing on the market has been highly concerned about the development after the success of last year to 4000-5000 daily output can not meet the market demand, LED gu10 high power, faced with huge product...Continue reading

Common faults for led solar street lighting system

The first case for the instrument panel of the led solar street lighting system is lit, there are two possibilities, an insufficient amount of oil the engine cannot be the complete lubrication of oil, under normal circumstances, the oil does not consume a lot of, so there may be leakage of engine oil. The second oil pump pressure and you should as soon as possible to stop to avoid traffic continue to operate without oil lubrication conditions resulting in engine damage. ...Continue reading

LED street lights occupy 20% of total lighting export

Last year, the lighting of the city's export value of about $ 1.345 billion, essentially flat year on year, but energy-saving light export volume has soared to become one of the highlights of the lighting exports. It is reported that nearly 85% of the lighting business in the city has set out to develop the design of the T8 LED street lights source or led high bay lights, and with the LED to achieve the upgrading of product structure. As one of the main export co...Continue reading

Dimmable led street light is no longer a myth

Ever since mankind realized must do everything possible to energy conservation, in order to solve the pressing problems of atmospheric warming, how to reduce electricity for lighting as an important issue on the agenda. Because 20% of the total energy consumption of electricity for lighting. Fortunately, energy efficient dimmable led street light, the LED itself than more than five times that of incandescent lamp, energy-saving fluorescent lamps, energy-saving lamps also ...Continue reading

The future development for high efficiency led lighting

Have already said that the best LED dimming is a simple PWM generator PWM dimming using the PWM dimming can be installed in the wall switch, and then use a potentiometer to control the PWM dimming ratio in order to achieve. To bright light switch off, then you need to add a pair of lines. It is not compatible with the original wall of the high efficiency led lighting switch leads. The lead of the led high bay lighting technology switch is only 2, you can while dimming c...Continue reading

The disadvantages of high intensity led lamp used in the house

1) high intensity led lamp is more than half a century old technology, it has many shortcomings explained above, is a long overdue elimination technology. It should be and incandescent lamps, halogen lamps and stage of history. 2) many of these chips claim has the PFC can improve the power factor, in fact, it only improves the load power factor as the high intensity led lamp, to make them look close to the pure resistance of incandescent and halogen lamps, and ha...Continue reading

RGB dimmable LED down lights using SCR

Ordinary incandescent and halogen lamps commonly used SCR to dimmer. Led high bay lights and RGB dimmable LED down lights is a pure resistance device, it does not require the input voltage sine wave, because the current waveform is always the same voltage waveform, so regardless of how the voltage waveform deviate from the sine wave, as long as the change of the valid values of the input voltage, can be dimming. SCR of the AC sine wave to be cut to achieve change its va...Continue reading

AC power supplied LED dimming technology

How to achieve the PWM dimming Concrete realization of the PWM dimming method in series with a MOS switch is in the LED load, the anode of the LED dimming technology with a constant current power supply. Then added to the gate of the MOS transistor with a PWM signal to quickly switch the led high bay in order to achieve dimming. Also a lot of constant current chip itself with a PWM led high bay interface, you can directly receive the PWM signal, and then output to...Continue reading

Change the brightness of the high intensity uv led

To work long hours at low brightness may make the step-down constant current source efficiency to reduce the temperature rise increased unable to work. Most people may think that just down to reduce the output power of constant-current source, so it can not cause the power consumption of high intensity uv led of the step-down constant current source to increase the temperature rise increased. Little do they know when the forward voltage drop caused by the lower forward ...Continue reading

Problems suffer for high lumen led flashlights used in daily life

In the specific implementation, however, adjust the forward current dimming may produce a more serious problem. We know that the c is usually driven DC-DC constant current drive power, and such constant current drive source is usually divided into two kinds of step-up or step-down (of course, the buck, but because of low efficiency, The prices are not commonly used). LED forward voltage is determined by its forward current. We can see from the volt-ampere cha...Continue reading

DC power supplied led dimming technology

Adjust the forward current to adjust the brightness to change the brightness of the LED is very easy to achieve. The first thought is to change the drive current, because the brightness of the led dimming technology is almost directly proportional to its drive current. 1.1 to adjust the forward current Current sense resistor to adjust the LED current to the most simple way is to change and LED load series, almost all DC-DC constant current chip has a detection...Continue reading
