- Q: LED bulb PC, will the white cover affect the color temperature of the finished lamp?
- I've got my lighting engineer to give you a professional answerBecause the light barrier is selective for light waves, that is to say, the transmittance of light at different wavelengths is inconsistent. When the lamp cover is covered, the luminous spectrum of the light source is changed because of the filtering of the lampshade, and the color temperature certainly has certain change.Professional lampshade company should have the detection of the passing rate of different wavelengths. Is your lampshade provided by professional lampshade company?
- Q: LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
- It is best not to direct contact with glue, glue because the thermal conductivity of aluminum than a lot of difference, even a thin layer will reduce the heat out of the speed of the screw can be used to aluminum plate and aluminum fastening together, the contact surface is smooth, when necessary, can use some conductive silicone grease amount
- Q: The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
- 3, the monomer minimum power is different. Incandescent power is a common monomer, 15W, energy-saving lamps common power 8W, and then low lighting effect is not good, and LED lamp monomer minimum power is very low, can be less than 1W.The luminescence principle of
- Q: How to choose the bulb power?
- Obviously, the designer doesn't want the ball lights to work at rated current, but there is a margin, so the light bulb will work more reliably. Because of the constant current source, current of each lamp is not 30mA, but 330mA/13=25mA, of course, the brightness of the lights will be smaller.
- Q: What's the cause of the noise during the aging of LED bulb bulbs?
- This should be the power problem. It's easy to make a noise because there are so many parts of the power supply.
- Q: LED bulb bulbs, do you need 3C certification now?
- Light source class is impossible to do, only lamps and lanterns class can do. For example, flat lamp, ceiling lamp and so on...However, CQC voluntary certification can be done.
- Q: Are there any differences between negative ion bulb and LED bulb?
- The negative ion belongs to bullshit type, the concept of things!
- Q: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
- If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem
- Q: What's the difference between a glass cap for a bulb and a PC hood?
- Transparency comparisonPC transparency is 90%, glass transparency is 95%, but the naked eye does not seem to distinguish between too big, because it is 5%, ha ha,Only several meters can be measured by instruments.
- Q: Detailed description of LED bulb lamp
- Healthy LED is a green light source. The LED lamp is driven by DC without flicker. Without infrared and ultraviolet components, without radiation pollution, it has high color rendering and has a strong luminous directionality, good dimming performance and no visual error when the color temperature changes
