Internal Circuitry Of LED Power Supplies

04:24 |


Shenzhen Excellent Top Electronics is the gloabal producer of LED Power Supplies. LED power supplies
are used extensively in lighting applications. Exactly where a SMPS does not start off and yes it isn't really clear why, it would help get the particular chopper drive by an outside signal resource to see exactly what subsequently performs. The one time period this is actually practical can be when a single transistor or even MOSFET can be used generating any push-pull waveform most likely isn't really worth it.

This specific will always be any risky course of action each available for you as well as the power supply. The switching frequency or over volume is probable unfamiliar but also for these kinds of assessments you'll be able to think it's within the 10 for you to kHz array. You'll be able to slow up the risk to some degree (to the particular provide in least) with a series bulb fill and/or running about diminished line voltage. The most important thing in order to avoid can be setting up an extremely prolonged pulse which will result in the particular large volume transformer saturating, quite a bit connected with current. In addition to likely any lifeless transistor and perchance other places if you experience practically nothing for you to limit the current. If you have the alternative, choose any thin pulse waveform to reduce on-time, and not push the good fortune of yours.

Likewise, when a power makes an attempt to get started yet cycles or even turns straight down, contemplate turning the particular controller chip coming from another supply to get rid of just about any problems from the transformer extracted voltage that typically works after startup.

Barriers in adoption of LED Lights

03:15 | Labels: , , , , , , , , ,


LED Lights have revolutionized the lighting industry since the good old days of Thomas Edison and technical advancements and improvements in manufacturing processes are making it all easy for consumers to adopt the fast growing lighting solution. But as of now there are few constrain or barriers which are keeping the consumers at bay from adopting LED as their primary source of lighting.

Up-front Purchasing Cost:

There are many areas where LED is an attractive economical option such as energy saving led outdoor bulbs or indoor led light bulbs. As far as the outdoor settings are concerned where the maintenance cost is far high than that of indoors so LED is a viable option. But the particular disadvantage in economic terms is the higher purchasing or up-front cost. At this time of financial crises, this can limit the sales of LEDs even when the long-term economic benefits are out setting the higher purchasing cost. The continuous drop in the prices of LED Lights by 15%-25% a year can induce the consumers to opt for LEDs in near future.

State of Awareness:

The early adopters of LEDs should be the major governments and multinational corporations, but still there is a great variation between the level of awareness of lighting managers from being alert to the existing situation of LED technology, and energy saving as a concern to being able to comprehend to proceed in procuring well-designed LED Lights. As the led technology is changing very rapidly therefore keeping up to date can be a daunting task. Manufacturers such as indoor led tube lights manufacturer can also play a critical part in creating awareness among the consumers.

If the above mentioned hurdles are eliminated then LED Lights can unquestionably be the consumers’ priority.

Commercial Viability of Indoor LED Lights

04:17 | Labels: , , , , , , , , , ,


LED Technology has taken the world by storm and it is inevitable that soon the LED Lights will take the crown of industry standard. There is tremendous scientific research being done on LED. Its components and the peripherals and new advancements in the technology are making LED Lights more energy efficient and hence cost-effective.

But there are some points one should keep in mind while choosing LED as their lighting solution. The current high cost of the Energy Saving LED Outdoor Bulbs is the main cause of concern while opting LED Lights as the primary lighting solution. Although due to technological advancement and scientific research the cost of these bulbs are gradually going down but still the unit cost is high. For Example: In comparison with a 25W traditional incandescent bulb, the replacing LED Bulb cost around $40. This shows that purchasing cost of LED is indeed high but the other fact which shouldn’t be ignored is that the operating cost of LED Light is significantly low than that of traditional substitutes and in the longer run opting the LED Light Bulbs is beneficial. The best value of using the LED Light is in commercial use such as Indoor LED Tube Lights Manufacturer where the lights are installed in order to run longer therefore the commercial viability is truly on display when LED Lights are being used commercially.

It will be fascinating to watch the scientific developments that are under process for indoor and residential application of LED Lights. The LEDs are widely being used outdoors (traffic signs, floodlights) but the real test for LED will be to “stand out” when it comes to indoor application of LED lights. There is still a lot of work that is to be done in order to make the LED Lights more cost effective (in terms of purchasing) and that day seems to be closer than we think considering the pace at which the technology is being unfold.

The industry users of LED Lights are confident the LED Lights of near future will be far more cost efficient and more eco-friendly than those of today’s LEDs and will eventually replace practically every type of Lamps that is being used today.

Plug-In the LED

00:10 | Labels: , , , , , ,


The common lightings that most of us use are traditional filament and halogen lights which are both inefficient and expensive.

The problem with most of the energy efficient lights is that the emission or quantity of light can be poor. In recent years, the boom in Energy Saving LED Outdoor Bulbs Lights technology have resulted in a new generation of LED Light Bulbs with the brightness that is either on par or even exceeds traditional incandescent and halogen bulbs.

If we compare the cost of let’s say a 30W bulbs to a 1W LED Equivalent, the cost of the bulb may be more but the operating cost will be around 30 times less. And not to mention the unusually longer life span of LED Bulb which is up to 20 times more than that of traditional bulbs.

The Indoor LED Tube Lights Manufacturer available in a wide range of shapes and sizes and are also available in nearly all fitting types so consumer won’t have to replace the whole fitting but the bulb. The shapes that are available are also easy on the eyes as compare to ugly halogen or incandescent bulb and the light output is also warm or cool depending on your choice. Moreover, the recent technological development and advancement in LED technology means that the investment consumers are making is beneficial in the long run.

LED Lights and Health

23:29 | Labels: , , , , , , , , , ,

When it comes to lightings, Energy Saving LED Outdoor Bulbs is unquestionably the best lighting solution which is widely available in the market. Cheaper, durable, and energy efficient these are the most renowned traits of LED Lights. From the health point of view LEDs are not behind any other substitute. In fact they are right in front. When it comes to lightings there are many factors that can be harmful. In this article, we try to discuss the characteristics of artificial lightings.


The most common hurdle when it comes to lighting is the flicker. For photosensitive people, flicker is the most dangerous problem. It may also affect people who spend most of their time in artificial lighting.


There are two major levels of flicker, one being the visible flicker and other being the invisible. On the frequency of around 3-70Hz, flicker is visible. Under normal circumstances no form of light falls into this category.

Fluorescent and other traditional lights operate at around 50-70Hz which is standard frequency of AC current. This is the frequency which can result in visible flicker but fluorescent tubes usually are of frequency which is two times of this frequency. In the most common cases, flicker usually occurs when the light is heating up to gain intensity or it is old.

On the other hand, LED Lights has the tendency to never flicker (unless intentionally designed). They are designed to lit up instantly and don’t have any so called ‘Warming Time’. For Example conventional Indoor LED Tube Lights Manufacturer work at around frequency of 12HZ. But here the main point is that they should be used with the right transformer. If not then they may flicker as the frequency will be manipulated.

On the other side of the range is Invisible Flicker, which occurs at frequency above 70Hz. This type is also capable of harming our health. This scenario is most with people who spend long time working in artificial lights. The point to be noted here is that this setback is not any light specific; it can lead to a simple headache to severe migraine as well.

Apart from flickering, the constant droning of lights can also cause health problems. With LED Lights this is not present or simply cannot occur. LED Lights on a brighter side also don’t contain any poisonous substances which can cause harm to ou health or is hazardous to the environment. The heat emission of LED Lights is minimal too and they neither emit any UV radiation which makes them even safer.

Recent technological advancement has also come up with LED Lights that are not just safe but also beneficial to our health. More scientific research is being conducted to make this form of lights beneficial for us in many other ways.

Choices in Lighting Solution

22:03 | Labels: , , , , , , , , , , ,


This article is intended to give consumers an insight regarding the lighting solutions focused on LED Lights discussing factors such as price, energy consumption, life and environment impact.

LED light are not the cheapest lighting solutions as it is quite an investment while you are purchasing them but on the other side of the picture traditional incandescent lights are cheap at the time of purchase but it becomes a real burden on your wallet when you review your electricity bills. Moreover in the world which is so “Environmental Friendly” nowadays, incandescent lights are also “bad” for the environment.

The traditional incandescent lights are not the correct choice. The cons are the relatively high energy consumption and the low rate of conversion. It is a well know fact that only 5% of energy is transformed into light by Incandescent lights (halogens or conventional). On the other side, due to the short life span, they have to be replaced very often.

If there is a (somewhat) better contender in front of LED Light it would be Fluorescent Lights. The lifespan is longer ranging from 1000 to 10000 hours and the conversion rate of energy into light is around 20%. But on the downside there is no sweeping change in your electricity bills. But the real damage is on the environment as they contain environment damaging chemicals like Mercury and Argon which are released whenever the light is broken.

But if the final choice is LED Lights then you are making a big march towards reducing energy consumption. The conversation rate that LED Lights can provide you is immeasurable. For example: Normal Energy Saving LED Outdoor Bulbs have a conversion rate of around 90% and they munch through only few watts when compared to traditional lights. The investment on the purchase of LED Light is high when compared to other options but it is a major cost saver in the longer run and has the capability to reduce the electricity bills by around 80% and that’s not it. The real cost saving is through the immensely longer life span of LED Lights.

The recent technological developments in LED Lights technology means that there is more to come not only there are new products coming in the market in forms of LED Panels, Indoor LED Tube Lights Manufacturer and LED Flood Lights etc LED is becoming or have become the full fledged lighting solution both indoor sand outdoors.
