Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?
If the material with better thermal conductivity, the lamp shell about 60 degrees is best.Reason:1: if the temperature is too high, that your radiator is too small.2: if the temperature is low, indicating that your calories did not lead out. (of course, if the radiator is too large and the temperature is low, but the bulb and tube are too heavy to pass by certification)
Q:Led the bulb is flashing. What's wrong with it? How do you fix it?
The general power supply too much heat to stimulate the overheating protection function itself with the power supply, power supply is a protection device, when the heat is too large, may cause it has an adverse effect on power and light, power will take the initiative to make the lamp power, rest, fully dissipated heat later. Bright. So, this is the power overheating protection at work. It will not be the case if the outer shell is enlarged or the room is ventilated and the heat should be cooled.
Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
With a high quality LED light, 6W will be enough;High brightness compared to incandescent lamp, more energy saving.
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:What's the reason why LED bulb gets a lot of heat?
LED light is a large amount of heat, more than 70% are calories. Different manufacturers are not very different
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:Seeking the production process of LED bulb... Thanks
First of all, of course, the preparation of materials, the specific operation of the lamp to practice, each lamp has different methods of assembly, there are different work instructions. Only through practice can we write good and practical processes. Figure is a flow chart of MR16 assembly.
Q:LED bulb w can replace 40W incandescent lamp
D lamp lumen value is ordinary incandescent lamp about 3 times, but LED ball bubble mask transmittance should be based on material, can use 10W or so LED acrylic mask ball bubble instead. Because I received a similar customer complaint, 7W's LED light bulb was replaced with an 20W energy-saving lamp, which was not bright enough.
Q:Choose which light bulb LED bulb is the healthiest
The two said warm light, power, color temperature and so on have little to do with health
Q:LED what are the bulb screws?
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.
