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:LED what kinds of screw bulbs are there?

LED bulb lights are E14, E27, E40, B22. The most common family is E27, also known as big headed screw. There are also some lamps, E14, called small headed screw. These two are the most common energy-saving light interface. Before there are B22, that is, the kind of card, also known as bayonet. It may be common in the countryside, but now it has been phased out. There are some industrial use of more E40, more than 80W energy saving lamps will be used, that is, the interface is relatively thick.

Q:Why can't the voice switch control the time of the LED bulb?

The power of LED bulb is much less than that of incandescent lamp, and the control loop and light bulb of simple sound control lamp are connected in series, and the load is different and the time delay is different

Q:What are the driving IC used in LED bulb?

M8900 can replace BP3309, SY5810 SY5840 MT7930, ME 8316, without modifying the circuit used directly.M8900Is an original side feedback, with single stage active PFC high precision LED constant current control chip, M8900 integrated single level active PFC line, can achieve higher power factor and very low total harmonic distortion, chip canThe quasi resonant mode is achieved, thereby achieving higher efficiency and reducing switching losses. M8900 features multiple protection functions to ensure system reliability, including LED open circuit protection, chip overvoltage protection, and UVLO deficiencyVoltage protection, LED short circuit protection, cycle by cycle current limiting, etc..

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

In general, every W is 60 to 100lm, the average is about 80lm, 15W is about 1200lm

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

Online shopping search: LED driver power 12-18w, the key to see the current must be 300mA, covering the 36V

Q:Are there any differences between negative ion bulb and LED bulb?

The brightness of LED anion bulb of each LED have good consistency, high color purity, light stability. 1W power, ultra low energy consumption. A variety of light colors are available for you to create a dream like color space. Built in negative ion generator, each cubic centimeter produces 3000000 negative ions that allow you to have a healthy air environment while you own light. Negative ions can effectively remove formaldehyde, benzene, toluene, ammonia, acetone, carbon monoxide, sulfur dioxide and other toxic gases, for your breathing health increased by a solid line of defense.

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.

Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb

5, the three have different service life. The service life of incandescent lamp is in 1000 hours or so, the service life of energy-saving lamp is in 6000-8000 hours, and the service life of LED lamp can reach more than 30 thousand hours.

Q:What are the types of LED bulb?

power LED bulb is the traditional incandescent lamp 1/10, half of the power of the energy-saving lamp, high efficiency and energy saving is the best
