5.FAQ

We have organized several common questions for our clients，may help you sincerely：

①How about your company？

A world class manufacturer & supplier of castings what is a good person steel，is one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

②How to guarantee the quality of the products？

We have with a better future system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

Q:What does "A19" mean in LED A19 bulb?: A stands for bubble type, A hemisphere bubble19 the numbers in the back indicate the size of the bulb (mm in diameter)On the market LED bulb generally has: hemisphere bubble lamp, A15, A17, A50, A60Global bubble G45, G55, G80, G120 and so on

Q:Detailed description of LED bulb lamp: A bulb can be said to be the highest cost of the driver, not the driver, light is not bright. And for the quality of a ball bubble

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:What does the LED bulb patch mean?: Performance of LED patch lamp:1, micro power consumption: LED lamp, 2W brightness is equivalent to 40W incandescent brightness, 3.6W brightness is equivalent, 60W incandescent brightness, brightness in the middle stronger.2 、 voltage adaptation range: nominal 220V lamp.3 、 the light distribution technology expands the LED point light source to the surface light source, increases the luminous surface, eliminates the glare, enhances the visual effect and eliminates the visual fatigue;4 、 lens and lampshade integrated design. At the same time, the lens has the functions of light gathering and protection, thereby avoiding repeated waste of light and making the product more concise and beautiful;5 、 high-power LED flat cluster package and radiator and lamp holder integrated design. The LED heat dissipation requirement and the service life are fully guaranteed, and the design of the LED lamp structure and the shape are completely satisfied, and the LED lamp has the distinctive characteristics of the lamp;6, Aluminum Alloy lamp body and the overall molding process, to ensure a good cooling effect, reducing the effective use of LED in the process of decay.7 、 no strobe. The pure DC work eliminates the visual fatigue caused by the strobe of the traditional light source; and the environment is green. No lead, mercury and other polluting elements, no pollution to the environment;8, impact resistance, resistance to leilijiang, no ultraviolet (UV) and infrared (IR) radiation. No filament and glass shell, no fragmentation of traditional lamp, no harm to human body, no radiation.

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.

Q:LED what kinds of screw bulbs are there?: There are E14, E27, E40, B22, LED bulb, only these screwsThe most commonly used are the E27 sizes, and the E14 is used in small bulbs, such as refrigerators and E40, for larger power.

Q:Will the power of the LED bulb grow longer and longer? Why?: Could you tell me the measurement method? - how about the side current and voltage? Or, whether direct measurement of active power under mains power supply?Also, can you tell me the circuit of LED bulb? DC power supply or AC power supply? Constant current module drive or RC current limiter? If the power supply is 12 volts low, is the resistor only current limiting?I feel something doesn't make sense......In one case, the longer the duration of the LED bulb, the greater the power:In some advanced LED bulb bulbs, an anti impact "slow start" circuit is added to the design, and a NTC (negative temperature coefficient) resistor is incorporated into the LED power supply circuit.Because of the larger resistance of NTC in cold state, the current of LED is smaller and the power is relatively small;With the use of electricity LED bulbs, NTC resistance temperature gradually increased, the resistance is reduced, the current of LED is also increased, so the power LED bulb also increases, temperature stability, until NTC resistance unchanged so far.

Q:Why can't the voice switch control the time of the LED bulb?: Current problem. The current is too weak. You don't have to use an electric meter to see if you can work properly without a light bulb. Change the timer switch.

Q:Led what's the flash of the bulb?: Should be the cheapest LED bulb, the lamp driver is not a constant current source, in the voltage fluctuations will appear flash.

Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?: Cannot connect directly. LED bulb is usually a series of LED series, and then parallel, generally about 12V. Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.
