LED energy-saving lamps maintenance knowledge

GUANGZHOU, China - April 23, 2015 - PRLog -- First of all to exclude false failure. To turn off the lights after energy-saving lamps have clearance of flash, this is not the quality problem of the lamp. The main reason is that electrical wiring is not standard, the switch is located in the zero line. As long as put into the zero line and the line of fire change can be on line. Use the switch with neon, still can form micro circulation way after turn off the lights, or borrow line installed double switch, will sometimes turn off the light after flashing phenomenon.

The Maintenance of led energy-saving lamps, for security measures should be taken: isolation transformer isolated grid.

A. LED energy-saving lamps can't normal lighted maintenance.

1. Common breakdown (short circuit), or for the resonant capacitor C6 pressure reducing (soft breakdown), for pressure should be replaced in the same capacity as the above 1 kv high-quality polyester or CBB capacitance.

2. Lamp filament. If black tubes is not serious, but on both ends of broken filament lamp feet parallel 0.047 u F / 400 v polyester capacitor after emergency use.

3. R1, R2, open circuit or variable values (general with R1 failure probability), use high quality resistance with resistance of 1/4 w substitution.

4. Triode. Such as found that only a triode open, but you can't change a, and should be replaced with a pair of pressure above 400 v model matching switch tube. Otherwise it's easy to have a light rolling or burn again.

5. Lights flashing. Black tubes without serious, look for virtual D5, D6, welding or open if D5, D6 soft breakdown or filter capacitor C1 leakage and bad, also can make the lights flashing.

6. Lights light up hard, sometimes touch lamp can light up or lights, this may be a C3, C4 capacity lack, not matching.

7. If a single small power energy-saving lamps light up after filament have red or light phenomenon, still should check whether there is any soft breakdown on D1 ~ D4, C1 whether installed backwards or leakage, the power part of the presence of short circuit, etc.

8. Choke L B and oscillation transformer core has a fracture. If single in core, pay attention to three points:

(1) core used to meet the requirements, otherwise may make the choke coil inductance value has great discrepancy, a dangerous precedent for energy-saving lamps;

(2) the magnetic gap not too small, in order to avoid magnetic saturation;

(3) the magnetic gap between with appropriate cushion lining mat, adhesive glue, and high temperature resistant flame retardant tape wrapped, and in case of loose. In addition to the B side of the same name cannot be wrong

9. Maintenance use trigger electronic ballast of the tube, should check the bidirectional trigger diode, mainly the tube type DB3, is commonly used in its two-way breakdown voltage of 32 + 4 v.

B. LED energy-saving lamps inner components obvious damage repair

1. Although not fuse, do not burn out into at the line and have obvious damage such as resistance, triode surely loss. This may be caused by aging the tubes, first followed by using the environment is poor, the other is likely to be caused by C1 lost capacity. For the former two kinds of circumstances, when replace the resistor, transistor, also had better replacement pairs of C3 and C4 small electrolysis. For the latter, C3 and C4 don't have to change, because C1 work under the condition of high pressure, be sure to select excellent heat-resistant electrolytic capacitor for substitution.

2. In the fuse, burn out into line line, if C1, Q1 and Q2 in good condition, you must individually from D1 to D4 for regular inspection and pressure test. Or all the D1 ~ D4 with excellent substitution.

3. C1 burst, such as with fuse, burn out into line phenomenon, should replace all from D1 to D4 and C1.

4. Only on one side of the Q2 resistance capacity, triode, burn out, should check whether the C2 is mainly has the breakdown.

5. If the high-frequency transformer is damaged, B available 30 0.32 mm high strength wire in 10 mm x 6 mm x 5 mm high frequency winding on the circular, T1, T2 for four laps; T3 is 8 (note that end. Choke L: lamp power 5 ~ 40 w, corresponding between 1.5 ~ 5.5 mH.

C. The electronic energy-saving lamps in the interference of other household electrical appliances.

1. L adjustable inductance or capacitance C2, so that they don't interfere with the remote control TV, and security.

D. Led energy-saving lamps should be paid attention to in daily use.

1. Led bulbs can't move light lamp of induction switch, delay switch, used in the circuit.

2. Led bulbs should avoid to use in high temperature and high humidity environment.

3. Led energy-saving lamps and other lighting lamps and lanterns, unfavorable and off frequently.
