Parameter:3W-15W 3W-10W use RC voltage-reducing. 12-15W use constant current SMD2835,Voltage220-240V BaseE27,240-1050Lm,RA＞80,2700K-6500K, Beam Angle 270 degree.Different types,different size
- Q:Secret LED bulb bubble price difference why so big?
- Structure. LED heat dissipation is very important, good bulb will be equipped with radiators, inexpensive, and its life can be imagined
- Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
- The light effects of the three are different. Incandescent light minimum generally below 20Lm/W, the energy-saving efficiency of light in the 60-70Lm/W, the LED ball screw energy-saving lamp in the global market, the quality of the naked light in 100Lm/W, with the outside door cover will drop more than 10%.
- 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 bulb with what type of LED beads?
- The LED bulb is mainly white and warm white two colors are white, the temperature is generally 6000-6500K color, the color of the sun light at noonWarm white temperature is 2700-3000K, yellow, similar to the sunset color temperature.
- Q:How to identify Ic constant current LED bulb?
- Let me tell you what. If the bulb is not damaged, the regulator needs a regulator to lower its voltage and see if the bulb's brightness is dark. If it follows, it is not a constant current source, but a blocking capacitor. If the voltage is greatly reduced, the brightness change is not constant, that is, the constant current source bulb (because the constant current source lamp can change between 80V--260V, the voltage is normal, and the output is constant).
- Q:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?
- Now the market LED lamps quality uneven. LED lamps need constant current and constant voltage drive to be durable. The cheap 3W LED plastic bulb power supply is only the drive of the resistance capacitance pressure drop. Drive rank: 1. constant current and constant voltage drive. 2. constant current non constant voltage drive. 3. constant pressure and no current drive. 4. resistance capacitance pressure drop drive (resistance capacitance voltage drop is the worst and cost is the cheapest)
- 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?
- Of course, the hotter the better, because for the same material, the hotter it is, the more heat the LED chips use, the less good the quality of the chips. The thermal characteristics of lamps is mainly to measure the junction temperature of LED Shenglai rather than the temperature of heat sink. Aluminum is commonly used in heat dissipation materials.
- Q:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
- It's possible to assemble your own bulb. The power used in the bulb is too large. It causes the gold wire to burn
- 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: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
