Why LED BULB Flicker on off?


Many of today’s modern and tech-savvy customers will already be aware of the all-new LED lighting systems. Benefits of such a lighting system boast to be pocket-friendly and in the long run, they also allow for great quality.
The best thing about LED lighting systems is the fact that they also claim to be extremely environmentally friendly. This comes as great news to those that are looking for a ‘green’ lighting alternative. The environment boasts only so many resources and if we don’t take action, these resources could soon run dry. This is where LED lighting systems come into play.
However there are some rules to follow when looking into such a lighting system, these include investing in the right fixtures and fittings. Without the correct system, consumers may begin to ask this question “why does my led bulb flicker when off?”
This annoying flicker may be due to the wiring of the lighting system, some low energy bulbs will however always flicker for a few seconds when turned off. If you are still unsure, it may be wise to invest in the help of an electrician. He or she will be able to check that the adequate lighting is in play.
LED lighting systems boast a huge and impressive life span, however, this life span will only be showcased to its full potential when accompanying to a adequate fixture. Certain GU10 LED bulbs will fit directly into an fluorescent fitting. Some however won’t and this is where a slight flickering may become clear or in the worse case scenario, extremely noticeable!
This flickering could be down to the convertor or driver in use. Not all bulbs require a converter, it is however important to check which systems do. This proof will allow you to get the most out of your newly purchased LED lighting structure.

LED candle bulbs


LED candle bulbs are designed as an energy-saving alternative for traditional candelabra lamps. These compact lamps operate on a 120 volt system, and can be inserted into any E12 candelabra base. E26 base options are also available. LED lighting technology is energy efficient, vibration resistant, and feature multi-directional beam patterns making LED lighting solutions ideal for general lighting applications. There are no hazardous waste materials, and all Green Lighting LED products are RoHS compliant. 
All of the LED candle bulbs listed below dim on commercial dimming systems. The dimming design uses the most updated All of the LED candle bulbs listed below dim on commercial dimming systems. The dimming design uses the most updated technology of Frequency and Peak Current Modulation, which provides even and stable dimming function ranged from 5% to 100% of full luminous flux.

What is COB chip for LED

COB 
COB, (Chips on Board) , multi LED chips are packaged together as one lighting module. When it light up, it looks like a lighting panel.. 
                                             
                                       
Why COB? --BackgroundLED(light emitting diode) is new technology with advantage of saving energy and very long lifespan. But all LED lightsource can not be faultless especially SMD, HP, flux LED etc. Compare to traditional lighting such as fluorescent lamp, as it is super bright in a small size, it cause uncomfortable glare. In case of no diffused optical lens used, such LEDs usually cause glare and zebra strips . But when optical lens or cover used, it will cause light loss when LED beam pass through this lens or cover.


How COB LED Light source works 

COB LED is multi chips packaged, it can 10 times more increase lighting area, so it avoid uncomfortable glare by the maximum extent. 
Auroras Lighting uses small size of chips to make COB LED package.
By now, for small size chip, ?some famous LED chip manufacturer can reach 249lm/watt @ 20mA. But big size LED chip can only reach 161lm/watt @350mA. The light efficacy decrease when chip size is bigger. Also when LED driver increase current to LED, the light efficacy per watt is even low.

The COB with small size chips will be a trend of LED light source package.
Lightspot holds the patent for invention for COB LED and lamp.

Application of COB Technology

2, LED lighting fixture which use COB LED light source
