Q: Where can LED bulb be used?: LED bulb is a new type of energy saving lamp to replace traditional incandescent bulb. The traditional incandescent lamp (lamp) of high energy consumption, short service life, in the global resource environment, has been gradually by governments to ban the production, instead is the product of electronic energy-saving lamp, electronic energy-saving lamp while improving the energy saving effect, but because of heavy metals using a lot of pollution of the environment, trend against the environment protection.

Q: LED what is the glue between the aluminum base of the bulb and the cooling aluminum?: Heat conductive adhesive is best.Heat conductive adhesive, also known as thermal conductive silica gel. Organic silica gel as the main body, adding fillers, thermal conductive materials and other polymer materials, mixed by silica gel, has better thermal conductivity, electrical insulation performance, widely used in electronic components. Also known as: thermal silica, silicone rubber, silicone heat, thermal conductivity of silicone. The accelerator is used to solidify a transformer, transistor, and other heating elements onto a printed circuit board assembly or radiator

Q: LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!: How many seconds delay? It won't take so long. How many bulbs do you usually soak in 0.5 seconds? A squeaky noise is usually a transformer or inductance whistle, and at least it shows a poor manufacturing process.

Q: LED what kinds of screw bulbs are there?: LED bulb adopts the existing method of incandescent lamp interface, the general screw is E27E14E40 (three). E for screw holes, figures for size, diameter, size. The most commonly used are the E27 sizes, and the E14 is used in small bulbs, such as refrigerators and E40, for larger power.

Q: What's the reason for the LED bulb strobe?: 8W offline LED driver GreenPoint reference design with solid state lighting standard energy star "as an example, the sine wave regulator side flyback power conversion does not provide constant energy to the primary bias, dynamic self supply (DSS) circuit can be activated and the light induced flicker. To avoid this problem, it is necessary to allow primary bias to be discharged at each half cycle, and accordingly, the values of the capacitance and resistance that constitute the bias circuit need to be appropriately chosen.

Q: How to identify Ic constant current LED bulb?: Hello, LED market is now very confused, this problem is the use of LED lamps of the users are more concerned about the problem, the so-called IC constant current drive power refers to the LED lamp (commonly known as the transformer) with a constant stream of multifunctional IC chip, the IC is generally 5-8 feet (depending on the model and decision scheme), role is to ensure that the current through LED lamp is controlled in a relatively constant parameter, ensure the long-term stability of LED lamp work at constant current. When the input or output voltage is changed, the current through LED remains constant, so the constant current IC of the LED light stability and service life is directly related to the IC also includes internal short circuit protection, overtemperature protection function of open protection etc.

Q: Will the power of the LED bulb grow longer and longer? Why?: In general, LED energy-saving lamps (including LED bulb bulbs) use a constant current drive that does not change the magnitude of the current with time or temperature, so it does not become more powerful as it grows for longer periods of time.On the other hand, if because of long time use leads to LED lamp temperature rise, according to the electrical properties of semiconductor, the PN junction voltage will also decreases with increasing temperature. Then, when the current is constant, a drop in the voltage drop means a decrease in power consumption, although the reduction is very small.

Q: LED what does "A60" mean by bulb 60? And what does "MR16" mean?: 60: diameter 60mm (metric unit) MR16: diameter is 16*1/8*25.4mm (Imperial units), although refers to the diameter, but the height and other dimensions are also prescribed

Q: Why can't the voice switch control the time of the LED bulb?: Originally white silk lamp, later replaced by LED bulb, with a light activated switch control, replaced by LED bulb, the lamp does not extinguish for 30 seconds
