Floodlight и spotlight в чем разница
As nouns the difference between spotlight and floodlight
is that spotlight is a bright, directional light or lamp, especially one used to illuminate the focus or center of attention on a stage while floodlight is a projector of a bright beam of light for use in theatres and studios; a flood.
Final Words
If you have spotlights, floodlights, or downlights in your home, which is your favorite?
Описание от продавца:
Количество светодиодов: 6 шт.
Мощность светодиодов: 3 Вт * 6 = 18 Вт
Напряжение питания: 9..30 В
Материал: алюминиевый сплав
Размеры: 15.0x4.0x4.0 см
Длина кабеля: около 20 см.
Задняя часть выполнена из литого металла с ребрами (скорее дизайна ради, чем охлаждения). Спереди пластиковый отражатель приклеен на герметик в корпус ПТФ. Степень защиты продавцом не указывается, но предполагаю, что она не ниже IP67. Кабель из ПВХ, сечение проводов (на глаз) 1мм2 (не ниже). Расстояние между верхней точкой крепежа и корпусом ПТФ 7 мм.
Для разбора ПТФ понадобилось нагреть корпус и аккуратно отделить пластиковый отражатель. Внутри находится плата, на которой смонтирован драйвер питания и сами светодиоды. Не сказал бы, что пайка идеальная, но выполнена аккуратно. Плата частично залита прозрачным компаундом. Есть ли под платой термопаста я проверять не стал, т.к. по тепловым показателям температура не поднималась выше 56С. Надпись на плате: 0718 1.2-0.42A 2016.04.23 NT
Замеренные характеристики:
При 16В потребление 0,53А;
При 14В потребление 0,6А;
При 12В потребление 0,76А;
При 10В потребление 0,35А.
Напряжение на ногах светодиодов на плате (слева направо):
16В: 3,26В 3,26В 3,27В 3,26В 3,27В 3,23В
14В: 3,26В 3,26В 3,27В 3,26В 3,30В 3,25В
10В: 2,99В 2,99В 3,00В 2,99В 3,00В 2,99В
С учётом постоянно-нормального напряжение автомобильной сети в 14В сделаны следующие замеры:
Световой поток одного светодиода: 240lm
Общий световой поток без отражателя: 1500lm
Общий световой поток с отражателем в сборе: 1300lm
Температура передней части платы после 15 мин. прогрева, макс.: 55С
Температура задней части корпуса после 15 мин. прогрева, макс.: 43С
Общий вывод: на первый взгляд ПТФ сделаны качественно, световая отдача в норме, перегрева не обнаружено — можно брать :). Но пространство между металлическим корпусом и пластиковым корпусом я залил герметиком — в этом месте будет грязесборник.

Where Is The Best Application?![kitchen]()
Since spotlights, floodlights, and downlights have different beam angles, it follows that each light is best suited to a different application.
Floodlights, on the other hand, tend to be used to illuminate larger areas such as car parks, warehouses, driveways, and sports pitches. Their broad-beamed nature means that floodlights are considered too harsh for indoor use, as they would make the space feel very artificial and harsh.
In terms of downlights, they are routinely used to create zones, navigate around space, and highlight critical areas. As they are installed into the surface, downlights are often found inside cabinets, and above workspaces or tables.
Which Is Better For the Kitchen?
Nowadays, most kitchens use tilt or eyeballs downlights as the primary source of light. They are very similar to spotlights, as they can be adjusted to ensure that all areas of the room are lit. However, they are favored due to their aesthetic appeal.
On top of this, spotlights are used over counters, islands, or tables. These are the areas that people are going to be preparing, cooking, and eating food, so they must be well-lit.
Floodlight or Spotlight: What Should You Use For Landscape?![backyard lights]()
When it comes to choosing landscape lighting, the key is to focus on the purpose of your lighting.
The downside of floodlights, nevertheless, is that you have no control over the light path. This means floodlights may be inappropriate if you have a small yard or close-by neighbors.
В нашем магазине вы можете выбрать светодиодные фары и балки с разными типами свечения (светового пучка).
FLOOD (флад) — аналог ближнего света — если нужно хорошее освещение вблизи
SPOT (спот) — аналог дальнего света — если нужна максимальная дальность
COMBINATION (комбо) — сочетание дальнего и ближнего
WORK LIGHT (рабочий свет) — если нужно хорошее освещение вблизи с захватом обочины
Учитывайте, что эти типы свечения не ограничены по вертикали — т.е. фары светят на 360 градусов вокруг.
Также в нашем каталоге есть фары головного освещения — которые имеют четкую свето-теневую границу. Их можно использовать при движении по дорогам

About Me
Hi, I am Eugen. I was always one of those kids who had all sorts of weird lighting gadgets for every occasion.
As I got older, my interest has overgrown into lighting design and how light impacts everything around us.
Now, I want to share my knowledge and experience about lighting with you on LED Lighting Info. You can read more about me here.
What Is The Difference Between Floodlight, Spotlight And Downlight?
The clue is in their names. Spotlights, floodlights, and downlights each have different beam widths. While spotlights give off a narrow beam, floodlights do the opposite by illuminating large areas. Downlights, whereas, sit somewhere in the middle, as they can have a variety of beam widths, but the light is fixed in a downward direction.
As verbs the difference between spotlight and floodlight
is that spotlight is to illuminate with a spotlight while floodlight is to enlighten or illuminate with floodlight.
What Are Floodlights, Spotlights And Downlights?
Spotlights Explained![spotlights]()
Spotlights are a concentrated light source. They produce narrow cones of light that can be adjusted and pointed in different directions.
The beam emitted by spotlights is approximately 45 degrees wide, which makes it easy to control. For this reason, spotlights are a popular choice for stage lighting as they can accurately highlight the person or object that is the center of attention.
Spotlights feature a mounting plate or fixing bracket that is attached directly to a wall or ceiling. These brackets are accompanied by single, double, triple, or quadruple moveable spotlights.
The most common LED spotlight bulbs are GU10s and MR16s. While GU10s operate at 240 volts, MR16s operate at 12 volts. 240 volts is the same voltage as the mains electricity supply, so GU10s can be plugged straight into existing or new fittings. MR16s, whereas, require an external transformer to decrease the mains voltage.
Floodlights Explained
An LED floodlight is made of four components: housing, a reflector, a yoke, and the diode. The housing surrounds the diode and prevents light from spilling frivolously in all directions. The housing is lined with a reflector that helps to maximize light output. Finally, a yoke is used to support, suspend, and rotate the floodlight.
Downlights Explained
As a whole, downlights are very diverse. They can either be recessed or flush to the surface, fixed or rotating, and have a narrow, medium, or wide beamwidth.
LED downlights can be categorized into the following groups:
- Fixed – light is emitted in a downwards direction and cannot be adjusted.
- Tilt – the centre of the fixture can be adjusted by around 20 degrees to move the direction of the beam.
- Eyeball – similar to tilt downlights but the centre sticks out to allow more flexibility.
- Wall Washers – feature a hinged housing that can be adjusted to spread light on walls or pictures.
Most downlights consist of a steel or aluminium casing that is hidden from view, and a decorative fascia. During installation, a hole is cut into the wall or ceiling and the downlights are held into place using springs or compression clips.
What Are The Differences?
In essence, the main difference between spotlights, floodlight, and downlight is their beam angle. Beam angle is the measurement of angles that are formed between the centre cone of light and the points on either side of the centre where the light’s intensity is 50 percent as bright.
| Type of Light | Beam Angle |
| Spotlight | 45° |
| Floodlight | 120° |
| Downlight | Varies from fixture to fixture |

Текущий вариант (в один ряд) был выбран под конкретный дизайн моей машины
ПТФки шли ровно месяц (бесплатная доставка), пришли в индивидуальных картонных упаковках (слегка помятых). В комплекте: ПТФ, крепёж и ключ шестигранник. Отражатель (совмещен с передним защитным пластиком) оказался немного «полированным», но на общее качество это не повлияло.
