LED driver ICs for high-CRI color-mix SSL applications

LED driver ICs for high-CRI color-mix SSL applications LED driver ICs that can independently power two LED channels, enabling lamps and luminaires that deliver both high-CRI, warm-white light, and high efficacy. The use of two-channel driver electronics is a requisite in a color-mixed white SSL products. The white and red or amber LEDs have different forward voltage characteristics. Moreover, more white than color LEDs are generally needed. And the driver has to adjust the relative drive currents during dimming to achieve an incandescent-like, dim-to-warm-CCT experience. In many cases today, SSL product developers must utilize two separate driver ICs to implement color-mixed designs. The ICs include a linear controller used to drive a primary channel of white LEDs and a buck controller designed to drive a color LED string. The IC requires external MOSFETs. Atmel made the decision not to integrate MOSFETs to provide product developers freedom in supporting a range of string vo...

LED lights glare pollution and high frequency flashing, is a very serious problem.

LED lights glare pollution and high frequency flashing, is a very serious problem. I saw a big circle in the online shopping platform, inside the vast majority of the LED lights , will not mention this, did not consider this, but, LED lights glare pollution and high frequency flashing is a very serious problem.

Light Bulbs, Lighting Tips

Light Bulbs, Lighting Tips When light is too direct or reflected too strongly off a surface, it can produce a brighter, more dazzling light called glare. In the home, glare most frequently occurs in task lighting fixtures such as desk and table lamps, but it can occur in general lighting as well. Glare is a primary cause of eye strain, which can be uncomfortable for your eyes and result in headaches, nausea, and other unpleasant symptoms. This makes it important to reduce the amount you experience in your home. Let's review some effective strategies for eliminating glare as a cause for eye strain.

LED lights flashing common causes and treatment

LED lights flashing common causes and treatment: Energy-saving lamps, LED lights turn off the power after the flash, check the switch control is zero line. If the wiring is correct, refer to the following methods: Usually the human eye can perceive light flicker up to 70 Hz, which is not perceived above this frequency. Therefore, in LED lighting applications, if the pulse signal frequency below 70 Hz low frequency components, the human eye will feel flicker. Of course, in a specific application, there are many factors that may cause the LED light to flash. For example, in off-line low-power LED lighting applications, a common power topology is an isolated flyback topology. In the case of an 8W off-line LED driver reference design that conforms to the Energy Star solid-state lighting standard, the sinusoidal square-wave power conversion of the flyback regulator does not provide constant energy to the primary bias, the dynamic self-powered (DSS) circuit May activate and cause...

LED Light Glare occurs in the following three forms

Glare is a two-fold problem in which lights are reflected off surrounding surfaces so that the light scatters and causes vision problems. It doesn’t interfere with night vision, but makes it difficult to identify and place objects. For the problems of LED glare, all the manufacturers have adopted a variety of methods,some use the brushed PC mask ,others adopt the frosted mask or use the special phosphor materials, etc. , but these methods are not ideal, the drawing masks can eliminate glare, but the flare phenomenon is more serious , our eye tend to be fatigue under this lamp, if we are exposed to it over a prolonged period of time , but also cause eye astigmatism ; while the light loss of those using the mask and cream frosted is too large , the effect is bad. The wrong kind of light, or too much light has been proven to have an impact on your health and quality of life. Glare occurs in the following three forms: Discomfort Glare – Discomfort glare is also known as psycho...

These light bulbs have a newer technology (MCOB) which use less energy and last longer

These light bulbs have a newer technology (MCOB) which use less energy and last longer. I had been buying CFL twist energy saver lightbulbs which I thought were nice, until I learned about these bulbs. The CFL energy saving bulbs I had last 12,000 hours and these MCOB HT-lights light bulbs last 35,000 hours. They are a little more expensive, but it's worth the money to invest because they use less energy and last more than twice as long. In the long run, you end up saving more money with the MCOB LED Bulbs. I also like the design and material these are made out of. If I were to drop one of these, I dont need to worry about it shattering like a CFL bulb would. They also don't get hot like CFL bulbs do. I think eventually, CFL bulbs will be phased out and all manufacturers will be selling MCOB bulbs. I got the daylight white colored ones and now would love to have a set of the warm color too. Definitely worth the investment and I would recommend these to everyone who buys st...

LED lights glare pollution, is a very serious problem. I saw a big circle in the online shopping platform, inside the vast majority of the LED lights , will not mention this, did not consider this, but, LED lights glare pollution is a very serious problem. I often have to design a variety of LED light source, the glare is the most feeling, sometimes look at the eyes of LED lights, will hurt for several minutes. Home with the LED lights, especially children, must pay attention to this problem, first, all lens type LED lights, it is best not to buy, but unfortunately I will not send a map, or sent to see you. You buy LED lights, especially the ceiling, downlight, ask the next is not the lens. If it is, it must be considered, the lens is focused, the LED light was originally high brightness, in a poly, it is quite dazzling, and if your home decoration when the installation location of the lamp did not follow the characteristics of LED lights To design, such as the living room ceiling...

E26, 10 watt LED light bulbs from ht-lights at a discount in exchange for an honest, unbiased review.

Takes some time getting use to, but much brighter, less energy used than other types of bulbs. These are the first LED lights that we have tried out thus far, and after using them in our living room for a few days now, we plan to eventually switch all of our bulbs out with them. Currently, we have these two bulbs in a ceiling fan light fixture along with a 14 watt CFL bulb. I can say they put off a much clearer, whiter light than the CFL and they are also a little brighter. It has taken us a little to get use to the light it produces, which has a color temperature of 4000 Kelvin, so it is much different than your average bulb, whether CFL or incandescent. However, they are growing on us each and every day. They are a 10 watt LED bulb, which is equivalent to 60 watts. We did try one of the bulbs out in our bathroom, which is a single bulb light fixture, and felt the light just wasn't bright enough for that room. So for the fixtures in our home that only require one bulb, we plan ...

high quality light bulb. It is time that LED light bulbs actually match the quality

Very high quality light bulb. It is time that LED light bulbs actually match the quality of an old style light bulb or CFC light bulb. Everything, from the color temperature to the brightness matches the quality of an old style bulb. But since it is an LED bulb, there are numerous amounts of benefits. By far the best benefit is the energy consumption. Traditional light bulbs waste a lot of energy since most of the energy is converted into heat. This not only waste more energy, it is potentially a fire hazard. These LED bulbs are cool and safe to touch, even after hours of use. These lights are BRIGHT. And that is not an exaggeration. These are well suitable for a ceiling fan to light up and entire room. As you can see in the picture I’ve attached, one light bulb is more than enough to light up my entire bathroom. I love this HT-lights  company , and am currently using them for most of my lighting solutions. They have reliable products and a wide variety of products, rang...

I received this led light bulbs for free in exchange for my honest and unbiased review.

Excellent product that works well and is fully compatible wherever incandescent or CFL bulbs were prior. I am slowly changing all the light bulbs in our house from older incandescents (when they burn out) and getting rid of those dangerous mercury-filled CFLs as quickly as I can! I'm glad I never made a big investment in them because they're dangerous if they break and not one of them has lasted anywhere near the hours they promised me (with most giving out 1/3 the way through!). All of the LED lights that I have used in the past are still working fine today. It's just that when they first came out they were very, very expensive. Now their cost has gone down considerably. Since they'll last for so many years I'm putting them in the hardest to reach areas first so I don't have to worry about it until the next decade of my life! Lol These bulbs are rated the same as a 12W CFL, but their light seems brighter, clearer, and crisper. It's a whiter light...

A unique bulb makes a very pretty display with a warm glow

A unique bulb makes a very pretty display with a warm glow I really like the style of these ht-lights led light bulbs they remind me of the old bulbs when I was a kid I really like the warm glow they put off and the amount of light for the size of the bulb I am using them in a chandelier that I have over my table and I really am pleased with the way they are working I gave them five stars based on the fact that I thought the description was accurate I love the design and the warm glow that they put off and the bulbs that I receive looked exactly like the picture and my personal opinion I think they are pretty neat I receive these bulbs at a reduced price in exchange for an honest review but that did not encourage me or influence me to give them five stars I based it solely on the bulbs and the performance of the bulbs and my personal opinion so I hope this review has helped https://www.amazon.com/gp/product/B01M9ENBCD/ https://www.amazon.com/gp/product/B01M7U5Q8U/

Great for decorative light fixtures

Great for decorative light fixtures if you are looking for a candelabra bulb base - this isn't it, so look elsewhere. Amazon needs to change the title to decorative versus candelabra. These are the standard bulb base used in most light fixtures - they are not the small base candelabra bulbs. The photo of the actual bulb is accurate which shows the base about as wide as the bulb, so we did know we were buying standard base bulbs from the photos. We live in an historic home with many beautiful light fixtures that are original to our home. The beauty of these fixtures lit depends greatly on the light bulbs in them and the standard base incandescent ht-lights style bulb was our go-to for most of our fixtures so they were lit beautifully. Imagine our horror when we found out these bulbs would be discontinued and the first round of replacements were the curly fluorescent bulbs. We about threw up thinking about how they would look in our fixtures so we did what all of our other hi...

White and bright LED bulb, PERFECT!

White and bright LED bulb, PERFECT! Brighter and much longer lasting than the normal bulbs I buy! This LED bulb is amazing! I never thought to buy an LED light for my house lights, but the quality and brightness that comes from this is outstanding! I really want to replace all my yellow glow light bulbs for these white glow LED bulbs, now that I have seen their greatness. The LED bulb really lights up the room and gives off a more natural light..no yellow tones at all, just a pure white hue. I included a picture of a standard light bulb beside this LED bulb to show the visual qualities, the LED really comes out on top here. You can see that the bulb is really made well and just overall looks better. The fact that it lasts for 35,000 hours is great and that means I save money buying bulbs. This would make a wonderful gift! Also would really make an elderly friend or family member grateful since you get so many hours of use from the LED bulb - someone who has trouble changing l...

Perfect replacement bulbs for recessed can lights

Perfect replacement bulbs for recessed can lights I received a review set and loved them (clean light, low power and good presentation) so much I bought more. It's been a long road getting decent light in my loft. The room has multiple recessed outlets, but not enough power to supply all those 60 watt bulbs, a computer, TV, plus the surge from a vacuum cleaner all at once. To fix this I moved over to CFLs, but the colors were awful, some took time to warm up and when they did... they were often too bright, and worst of all they didn't last nearly as long as they should. I'm pretty sure their short life was due to mild power drops that wore on their circuitry, so even though I don't have dimmers in that room, I am happy that these are dimmable so that they are prepared to handle partial power drops. I'll try to remember to update this review when they do fail, but according to the estimates that may be in over 20 years ;). I found that these turn on very q...

These LED light bulbs look nice once installed

Nice flat look. Output is a warm color, but not quite as warm as the old bulbs. All in all a great bulb. These LED light bulbs look nice once installed. Much better than the globe look of my older ones. The light output is pretty much what I got from my old bulbs. I replaced one and compared this with the other one in an adjacent fixture. However, these are not quite as warm as the old bulb. They are close, but it is noticeable that the light output is not as 'warm' as the other. A bit more, not much, harsh. Made the color of the wall stand out. That being said, I was comparing the new vs the old which was right next to it. If you only are using these bulbs you probably won't notice the difference. It is a warm output which is nice. But as I said not exactly the output of the old bulb. All in all I like the flat look. And the output is just fine. And of course the energy savings is great. You should be quite happy with these LED bulbs.

HT-lights LED Bulbs CERAMIC MCOB LED Module With Function of Insulativity as Well as Heat Conduction. 10 watt 900 lumens 3000k (60 watt equivalent) Concord Torchiere Lamp This floor lamp really surprised me. I've owned a few over the years and never felt the need to get all spendy with them, so I tend to purchase cheaper varieties. That said, this lamp is built like a tank and it looks pretty spiffy too. I purchased it to be the main light in our bedroom, positioned it in the corner behind the nightstand, and put in a HT-lights LED Bulbs CERAMIC MCOB LED Module With Function of Insulativity as Well as Heat Conduction. 10 watt 900 lumens 3000k (60 watt equivalent). My only complaint, and it's not really a complaint, is that the lamp shade is just a wee bit too short for my liking, another half inch or so would be perfect. If you're bulbs are longish, they may stick out of the top a tiny bit. It's not a deal breaker at all, just something to consider.

Good and Efficient LED Bulb 75 watt Equivalent

Good and Efficient LED Bulb 75 watt Equivalent I’m into natural light, so I don’t usually gravitate toward the LED bulbs . They are usually too bright, and I would prefer to open windows and get natural light from outside and during the night, if they are too over-powering and you have 4 light bulbs in one unit, I end up switching them to lower watt bulbs. This bulb is 75 watts, which is usually too much for me in our living area, since we have fans with 4 bulbs and 4-75 watt bulbs would be too much, so I used it in an accent light that has only 1 bulb and was in a dim area. I had an Edison bulb in this one and it was too dim when I repurposed the room. This bulb is perfect, it gives a beautiful light they call “daylight.” It was a pleasant color. I used a dimmable switch, and it works well. Overall, this is a good bulb and the fact that they aren’t glass makes it easier to handle.
