LED Strip Light Based on the test results
Design of Electrical Parameters for LED Lamps
According to the test results, LED white light in the drive current lower case, the smaller the heat emitted, of course, the brightness is also smaller. According to the survey, LED solar lighting circuit planning, LED lights with the quality of the lamp beads must be made of material production, otherwise it is good to see the use of the effect, LED drive current is usually only 5-10mA; lamps used in the number of beads With a large commodity, such as reaching more than 500, or more, the drive current is usually only 10-15mA, and usually the popular LED using lighting drive current, only 15-18mA, few people to the current planning to 20mA or more of. The test results are also marked, in the 14mA drive current, and, plus the lid airtight, inside the air temperature reaches 71 degrees in the environment, low-bad goods, thousands of small light decline zero, 2000 small Shao light failure of 3% , Which shows that this low-decline LED white light in such an environment has reached its maximum limit, and then that is a great harm to it. As the aging of the aging board with no cooling function, so the heat generated when the LED operation is basically can not be transmitted to the outside. The test proved this point. Aging board inside the air temperature has reached 101 degrees of high temperature, aging board lid surface temperature is only 53 degrees, a difference of several degrees. LED lights with the verification of the performance of the entire product to the ultimate full range of functions. This shows that the planning of this plastic cover is basically no thermal function. But the usual lighting planning, are taking into account the function of heat conduction. Therefore, the summary, LED lamp beads operating electrical parameters of the planning to be based on the actual situation, if the lamp heat conduction function is excellent, LED white light drive current increase is not important, due to LED lamp beads work occurred Heat can be exported to the outside instant, no harm to the LED, that is, the best care of the LED. On the contrary, if the thermal insulation of the lamp function perfunctory, the best plan to be smaller, let it put some less heat out.
First, the circuit status: Please check whether the circuit is connected, whether the contact is bad, whether the light bar positive and negative reverse.
Second, the physical damage: LED lights with the production, transportation, preservation may also lead to no light, the following are eight reasons not bright:
1, LED flexible lamp with the packaging protection is imperfect, resulting in the transport process by the impact of the lamp beads damage.
2, LED flexible light with the welding point of the phenomenon of solder joint, the vibration during the transport caused by falling off the solder joint led to light.
3, LED flexible lamp with less solder, solder joints easy to fall off.
