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:Secret LED bulb bubble price difference why so big?

Remember, cheap, no good goods, the market price of less than 15 yuan bulb said that their quality is not credible.

Q:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!

Power supply must be constant current power supply. This must, do not have that resistance. The constant current source resolution methods, there is no power is apart of a 8 foot IC, if not, no junk to, also not all the IC are good stuff, a famous lighting city have specialized quality of constant current power supply.

Q:LED thread specifications for bulb bulbs?

Commonly used thread specification: E27 screw.Commonly used household ordinary E27 spiral lamp holder;

Q:What brand of LED bulb is good in quality?

What brand of LED bulb is good? LED bulb has replaced the ordinary fluorescent lamp and incandescent lamp gradually, with the market demand is more and more big, and the production of the LED lamp threshold is very low, so a lot of small family workshop also began assembling production of LED lamps, the technical content is low, without testing and certification of products, also began to circulate on the market.

Q:Are there any differences between negative ion bulb and LED bulb?

LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.

Q:Led the bulb is flashing. What's wrong with it? How do you fix it?

There is a drive power failure, and if you do not electronic repair ah, it is recommended to return directly to another driver, generally have 1 years warranty period

Q:Want to find common features, unified purchase accessories repair!

The most common problem is that 1, the drive power is broken 2, the light source due to excessive or excessive flow leading to necrosis

Q:Detailed description of LED bulb lamp

Using high quality, high-power LED as a light source, energy saving, environmental protection, and high brightness, long life

Q:What does the LED bulb patch mean?

According to different applications, different size, cooling scheme and luminous effect of.LED packaging forms. At present, according to the classification of LED package are mainly Lamp-LED, TOP-LED, Side-LED, SMD-LED, High-Power-LED, Flip Chip-LED Lamp-LED (vertical LED) emerged in the early Lamp-LED is in line LED, it adopts the form of sealing packaging. The potting process is the first injection of liquid epoxy resin in LED molding cavity, and then insert the pressure LED bracket welding, in the oven make epoxy resin after curing, the LED from the cavity from the molding. Due to the relatively simple fabrication process, low cost, have a higher market share. (SMD-LED surface mount LED) patch LED is pasted on the surface of a wiring board, suitable for SMT processing, can be reflow, a good solution to the brightness, perspective, smoothness, consistency, reliability and other issues, the The lighter PCB plate and a reflecting layer material, improved to remove the carbon steel pin dip LED heavier, the display of epoxy resin less reflective layer needs to fill, to reduce the size, reduce the weight. In this way, the surface mount LED can easily reduce the weight of the final product in half, make the application more perfect.
