Q:In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate

The heat sink temperature and the temperature of the radiator is not the same, the heat sink through thermal grease or other heat conducting medium to heat to the radiator, the temperature will not coincide. And the temperature inside and outside the radiator is also different.

Q:What are the characteristics of LED bulb?

LED bulb advantages: energy saving: the same brightness, power consumption for ordinary energy-saving lamps 1/4. Environmental protection: no harmful substances such as mercury, no pollution to the environment. (experts point out that mercury contained in a fluorescent energy-saving lamp can contaminate 180 tons of water sources). Economy: as a result of electricity saving, electricity costs can be reduced, and the cost of the lamps can be recovered for one and a half years. A family can save tens of thousands of yuan a month. Low carbon: saving electricity is equivalent to reducing carbon emissions. Long life: LED lamp life of 50 thousand hours, six hours a day, that is, 20 years of life. The price depends on how many watts you need, and the price varies with the wattage. Now the family uses "lightning man" led, very good, the price, quality, those are good, you can go and see. Hope to help you.

Q:What is the 15 Watt lumen of the LED bulb?

Each brand has different bulb qualities, probably around 1W between 60-85LM/W.

Q:What's the reason for the LED bulb strobe?

Currently on the market with single stage PFC driver circuit, there will be strobe, causing the flash because the ripple is too large. Single stage pFC circuits are not possible

Q:What's the cause of the noise during the aging of LED bulb bulbs?

The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.

Q:How does the LED bulb go with the power?

Generally we use the LED lights, 1W, 2W, 3W, 12W, and so on, the factory has been set in advance, directly connected to the 220 volt power supply can be, and do not need to be so complicated.

Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?

If the material with better thermal conductivity, the lamp shell about 60 degrees is best.Reason:1: if the temperature is too high, that your radiator is too small.2: if the temperature is low, indicating that your calories did not lead out. (of course, if the radiator is too large and the temperature is low, but the bulb and tube are too heavy to pass by certification)

Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?

With a high quality LED light, 6W will be enough;High brightness compared to incandescent lamp, more energy saving.

Q:LED how does the bulb return electricity?

maybe because Make the question clearWhat is the return current?

Q:What advantages does LED bulb replace energy saving lamp?

The LED lamp is solid-state lighting, if all LED lamps a year remaining nearly three electric power Three Gorges hydropower station, the country.
