- 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 choose the bulb power?
- If the public is not high, the quality requirements, and to control the price, you can choose non isolated, because it does not require isolation transformer, so the cost is relatively low, but the aluminum substrate voltage requirements is relatively high, otherwise there may be charged radiator, and still light outside is not very beautiful.
- Q: What's the cause of the noise during the aging of LED bulb bulbs?
- Either AC or DC LED lighting there will be a power module, a small hidden in the lamp body, the daily working state can produce high temperature, if the AC power supply temperature will be higher, because the lamp body appears to flicker, high temperature and long time will lead to the power supply module parts welding, weld or aging, so a lot of alternating current LED lighting the metal shell, to facilitate heat dissipation, the DC power supply is adopted to eliminate the flicker, reduces the electrical power, so the DC temperature should be low.
- Q: In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate
- LED work environment refers to the external work room temperature, LED lamps also have a working temperature, general LED lamp in the case of work, the external temperature is below 65 degrees is normal.
- Q: What are the characteristics of LED bulb?
- Energy saving research data show that, as LED is a cold light source, semiconductor lighting itself has no pollution to the environment, and compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of ordinary incandescent lamp and 1/2 of fluorescent lamp tube. If we replace 50% of our traditional lighting with LED at present, the amount of electricity we save every year will be equivalent to the sum of the total power generated by the Three Gorges power station, and the energy saving benefits will be considerable. LED, the lightning man at home, is pretty good
- Q: Is it possible to manually weld LED bulb bulbs?
- As long as the welding technology clearance is possible or OK
- Q: Want to find common features, unified purchase accessories repair!
- Common problems, a lamp is broken, the heat is not good cause, most likely it is a bad driver. As for the aluminum substrate, it should not be bad
- 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: How did the trademark on the LED bulb go up?
- Laser printing and screen printing, pad printing can be, look at the needs and equipment.
- 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
