Indoor LED Light PCB Maintenance Methods Which

Indoor LED Light PCB maintenance methods which
In the long-term use of these LED fluorescent lamps, LED bulbs and other indoor LED lamps inevitably occupy dust and other dirt, which makes cleaning and maintenance work is particularly important.
If the Indoor LED Light PCB cleaning and maintenance work is not in place, it is easy to shorten the life of the lamp. Indoor LED Light PCB professional and technical personnel, the appropriate maintenance cleaning to help improve the brightness of indoor LED lamps.
If you do not maintain a year, the brightness of indoor LED lamps will drop by about 20%; if laissez-faire, lamp, etc. in a dirty state, 1 year time brightness will be reduced by 20%; in the kitchen and other dirty places, then Indoor LED Light PCB brightness will be reduced by 40%. Therefore, regular cleaning and maintenance is to ensure that the brightness of Indoor LED Light PCB tips. In the cleaning and maintenance should be careful not to change the structure of Indoor LED Light PCB, and do not casually replace the Indoor LED Light PCB parts, after the end of cleaning and maintenance, should be installed as the original Indoor LED Light PCB, do not miss, misplaced lighting parts.
In the specific cleaning and maintenance of indoor LED lamps, it is best not to use water to clean, as long as the dry wipes can be wiped with water, if not careful to touch the water to try to dry, avoid turning on the lights immediately wipe with a wet cloth, because the Indoor LED Light PCB bulb high temperature water burst. In the clean, the cloth cover can not flush, the application of dry cleaning agent, if the glass material, available water, light the skeleton as long as the cloth can be wiped. Washing mirror with vinegar lamp is a good way. Will be eating vinegar about a beer bottle into the amount of half pot of water, mix thoroughly, the wipes in the vinegar water, wring the wipes can wipe the dust on the lamps. As the vinegar is clean and prevent the effect of static electricity, so wipe with the vinegar indoor LED lamps are not only bright and easy to dust dust. Clean the lamp body, use a soft dry cotton gently wipe, the action should be kept from top to bottom, do not rub back and forth. Clean the indoor LED shade, it is appropriate to clean the feather duster with light, so as not to fouling the lampshade or lead to deformation. Clean the Indoor LED Light PCB bulb, you should turn off the lights and do not turn the clockwise direction of the bulb, to avoid too tight peeling off the lamp cap.
 Misunderstanding 1, the actual life expectancy is too high
LED manufacturers expect LED life to reach 100,000 hours MTBF (average trouble-free time, the standard used by traditional lighting manufacturers to measure light source life). However, like all basic light sources, the luminous lumen of the Indoor LED Light PCB also fades with time. Therefore, although the Indoor LED Light PCB emission time can be very long, MTBF is not the only consideration to determine the service life. The attenuation of LED lumens is affected by many environmental conditions such as ambient temperature, humidity and ventilation. Lumen attenuation is also affected by control, thermal management, current levels and many other electrical design considerations.
Many sales staff in the promotion of Indoor LED Light PCB for some reason may give customers some fuzzy information, resulting in misleading, such as LED life of about 100,000 hours, where the 100,000 hours is the manufacturer expected the Indoor LED Light PCB Service life. But as a light source of lighting, the brightness of the lamp has a gradual decay of the process of darkening (such as fluorescent lamps, energy-saving lamps), this process referred to as light failure. Therefore, consumers in the purchase of LED to pay attention to its decline in light speed, rather than the use of time, consumers do not expect the actual life expectancy is too high.
Misunderstanding 2, the actual angle of light as an effective angle
Indoor LED Light PCB angle is divided into effective angle and the actual light angle. The luminous intensity value is half the direction of the axial intensity and the direction of the light-emitting axial (normal) is the effective angle. Half of the half angle of the angle (or half power angle) is the actual light angle. In the axial strength of half the angle because the light is too weak in practical applications do not count the effective angle.
Therefore, consumers in the purchase of products should pay attention to the actual light angle of the product, calculate the number of products used in the project, the actual light angle prevail, effective light angle can only be used as a reference value.
