Q:LED bulb with what type of LED beads?

There are many LED bulbs with LED lamp types, different lighting manufacturers will adopt different LED models, at present, most of the 2835, 5730 beads, beads are 0.5W-1W LED beads, specific type: PL-P2835DW-C8-R3-C2/ PL-P5730EDW-C8-R3-C2

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:What is the 15 Watt lumen of the LED bulb?

In general, every W is 60 to 100lm, the average is about 80lm, 15W is about 1200lm

Q:What's the reason for the LED bulb strobe?

If this resonant characteristic causes the input current to fall below the TRIAC sustaining current, the TRIAC will turn off. After a short delay, the TRIAC usually switches on and fires the same resonance. In the 1.5 cycle of the input power waveform, this series of events may be repeated several times to form visible LED flashes. To cope with this problem, a key requirement of TRIAC dimming is that the input capacitance of the EMI filter is very low and that the capacitor is decoupled through the TRIAC and the winding impedance. According to the formula, if the capacitance of the dimming module is reduced, the resistance of the resonant circuit can be increased, and the oscillation is suppressed in principle, and the desired circuit work is resumed.

Q:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?

Depending on your application and cost, there's no way to say which is absolutely good;If the occasion is appropriate and the cost is not urgent, buy a drive.

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:60W how many lumens and how many W LED bulb does incandescent bulb replace?

A LED lamp lumens general good point value is above 100;The brightness of 60W incandescent lamp compares with LED lamp difference is 10 times;

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

The proposed open, lamp is broken, can find light black or other unusual circumstances, bad power supply at the circuit board and components have the same burn what, under normal circumstances is such.

Q:What's the reason why LED bulb gets a lot of heat?

If the radiator is about the same size, it's not nice to touch the low temperature, because the heat accumulates in it and doesn't come out. The.LED lamp doesn't last long

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.
