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 forging in carbon steel and alloy 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 established the international advanced quality management 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.

③How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.

Q:What happens if the 12vled lights are connected to the 24V transformer?: Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on. When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.

Q:Can the light belt be connected directly to the alternating current of 220 volts? Is it necessary to install a converter?: Can the light belt be connected directly to the 220 volt alternating current, depending on the specific type?.The lamp belt is divided into a high voltage lamp belt and a low voltage lamp belt, and the high-voltage lamp belt is provided with a conversion module, and the utility model can be directly connected with the 220V voltage. The low-voltage lamp belt is driven by a direct current and must be connected with the converted DC power supply.

Q:What kind of material does the light belt have?: Later developed into a flexible circuit board is used FPC as carrier, because of its simpler processing technology, quality is easier to control, longer life, higher brightness and color and gradually replaced the earlier process, become the trend.Because the lamp belt is generally welded LED, so there are many LED lights, but because the noun is too long and simplified into a band

Q:What do you mean by "LED" belt model 5O5O and 3528?: This means that the LED chip is enclosed in a bracket and the dimensions of the stent. 5050:5mm*5mm; 3528; 35mm*28mm. Just structure size.

Q:LED lights with 0-10V dimming when flashing what reason?: After the thyristor is switched on, the circuit is not resistive, and the current oscillation occurs due to the capacitance and inductance. When the current oscillates below the thyristor to maintain the current, the thyristor is switched off and then triggered again.

Q:How much band wavelength does LED blue light have?: The light varies at different wavelengths, probably around 463-475nm.Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.

Q:What are the main features and advantages of LED lamp belts?: 1, small size, high brightness2, energy saving3, efficient and stable, no shadow at the junction.4, support dimming, create lighting environment.

Q:LED lamp with main lighting, how many watts per meter?: How long will it take to see the distance?! The common spacing is 33mm, the power 7.2W per meter, 30, and the voltage is 12V.This type of light belt should meet the basic requirements of lighting, 5 meters or more can be. Depends on your indoor brightness requirements,Also, pay attention to the length of the light band and preferably double head light!

Q:What's the brightness of the LED light band? Can I use it for lighting?: A lot of the workshop production line, or sell jewelry, watches, mobile phone glass counters are lit by the lamp. If you are in the cupboard, in front of the computer, these places still can illuminate the whole room. If it is recommended to buy LED fluorescent tube. No problem. Lighting decoration or vision space is too big the effect is not ideal. After all, he is a linear light source.

Q:How about the wattage of the hidden LED lamp belt?: The LED has different chips that cause different currents. For example: there are 0.011A; 0.015A; 0.028A and so on, it should be said that different batches of LED chip will have different values of the current, so each batch should be measured by instruments. In general, the 30 light / meter band will use a larger current of LED. For example: 0.028A, calculate the power per meter (30 / 3: lamp lamp group) * (12V * 0.028A) =3.36W; and 60 meters of lamp / lamp with LED will use less current to produce, for example: 0.011A, calculate the power per meter (60 / 3: lamp lamp group (x) 12V * 0.011A =2.64W). The use of resistance but also according to your current input voltage and depending on LED, because LED rated current is 20MA, but the actual application generally do not use 20MA, usually 15--18MA! To the series resistance, by Ohm's law can be counted by U=IR.
