Q: LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?: Speaking of attention should be to see if the light is even, PC material there are no scratches, spots and the like. It is difficult to test the proportion of raw materials used in PC materials, which is related to the aging time of PC materials.In addition, we should pay attention to anti-static.

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: Can the bulb's true life reach 30000~50000 by LED?: The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.

Q: LED how does the bulb return electricity?: maybe because Make the question clearWhat is the return current?

Q: What are the driving IC used in LED bulb?: MT7930, LM3445MM do bulb bulb, the effect is also ok.

Q: What are the requirements of the LED series inspection specification for bulb bulbs?: The temperature rise of the finished lamp is not more than 120K. The temperature rise is equivalent to the maximum value of 60W incandescent lamp.

Q: LED can the bulb be used in the bathroom?: Kitchen lighting bathroom and kitchen with special waterproof, but the working voltage of LED is low, LED lamp is also a big problem in the use of a water vapor environment, general heat sink should be no problem, is such as the use of aluminum shell, like plastic shell can not, because they on the cold and hot air convection cooling, casing is provided with a hole for air inside and outside the exchange, will put into the high-pressure part of water vapor driven, it will affect the service life.

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: What's the difference between a glass cap for a bulb and a PC hood?: ProcessabilityMachinable, blister, special-shaped processing PC easier.

Q: LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?: LED bulb: directly driven by not using AC-LED light source, light effect of the whole lamp life (compared with driving security; some) integrated LED relative heat transfer to the high requirements, high cost, simple assembly, do a single power source in low cost, high light efficiency.
