Downlight is a lighting fixture installed on the ceiling. Other names for downlights are can light or pot light. There are three ways to install downlights:
1.Recessed installation on the ceiling with a hole.
2.Surface mounted on the ceiling.
3.Hoisted to the ceiling by a boom or chain.
Most people choose to recesse installation down lights. Downlights ranging from 2.5″ to 10″ are available on the market. The most used are 3″, 4″, 6″, and 8″. As a compact lamp, the beam angle emitted by the downlight is limited. Downlights can be used for general lighting or directional lighting for emphasized areas. You can see that many walls have a beam of light shining on the wall, which is downlight with a narrow angle as a wall washer. Due to the hidden feature of the recessed downlight, people can see the light but not the lamp. Downlight fixtures have multiple functions and are commonly used by people.
Traditional downlights include downlight fitting and light source. The light source usually uses incandescent lamps, halogen lamps and compact fluorescent lamps (CFL). These light sources have high energy consumption and are not environmentally friendly. Most of them have been replaced by LED lamps. These LED lamps include GU10 LED bulbs, LED bulbs, LED corn lights, PAR lamps, BR lamps, etc. Downlight fittings vary in depth, which causes the LED lamps installed to protrude sometimes. The integrated LED downlight solves this problem, so LED downlight is more and more popular.
LED downlight has superior performance and gradually replaced the traditional down light fitting. The LED down light heat sink is made of ADC12 die-cast aluminum or high-strength aluminum alloy, which has excellent heat dissipation performance. Use a clip on the left and right to fix the LED down light on the ceiling. Some LED downlights use a diffuser to make the down light emit soft light, and some LED downlights use a lens to make the light from the downlight more prominent in a certain area. Some LED downlights can even adjust the direction so that you can focus the light wherever you want. Fire rated materials are added to the ring of the LED downlight to make a fire rated LED downlight to prevent the rapid spread of fire when a fire occurs. We can design the LED down light to have a waterproof function, so that we can use the IP65 LED downlight in the bathroom or outdoors.
Today’s light fixtures are getting smarter. We install sensor for downlights to form sensor LED downlight. The LED down light turns on automatically when we are walking in the aisle, and turns off automatically when we leave. Sensor downlight is both convenient and energy efficient. If we equip LED downlights with dimmable drivers to form dimmable LED downlights, we can adjust the brightness of dimmable downlights through the dimmer. There are three types of LED downlighter dimming systems:
- SCR dimming.
- 0-10V (1-10V) dimming.
- Dali dimming.
There is a kind of smart LED downlights, we can not only adjust the brightness of the LED downlight through the dimmer, but also change the color temperature of the LED down lighting by quickly switching on and off the switch. With the advent of the Internet era, smart downlight control has also entered the Internet of Things era. We can use wifi or bluetooth to control RGB LED downlight to turn on or off, color change, brightness adjustment.
Smart LED downlights bring us convenience, but we cannot ignore the importance of color temperature and color rendering index. SMD LED downlight and COB LED downlight also have excellent color rendering index. The higher color rendering index, the more accurate you see the true color of objects, and the more it can reflect the original natural color of objects. It is particularly important for application in museums and display lighting. When the color rendering index is greater than 80ra, you can reflect the variety of life, this is a warm living atmosphere. Now the color rendering index of LED is greater than 95ra, getting closer and closer to the original primary color of the sun.

1. What is LED Downlight?
LED downlights are products developed on the basis of traditional downlights with new LED light sources. Compared with traditional downlights, LED downlight has the following advantages: energy saving, long life, good color rendering, low carbon, fast response speed. LED down light is a kind of fixed direction light-emitting lighting fixture. Install downlights you can chooce recessed or surface mounted. LED downlight has the properties of directional lighting, and only its opposite can receive light.
The beam angle of downlights is divided into two types: spotlight and floodlight: The light of LED downlight of spotlight is more concentrated. The contrast between light and dark is strong. The illuminated object is more prominent. The illuminance is higher. The light of LED downlight of flood light is more scattered. The light can be evenly distributed to every corner, so that there is no dark area in the entire space.
According to the installation method, downlights can be divided into LED downlight recessed, surface mount can light. According to the shape, LED downlights can be divided into round LED downlights and square LED downlights.
2. What are Fire Rated LED Downlights?
LED fire rated downlights are a kind of many types of LED downlights. By adding fire-insulating materials to the joints of the radiator of LED downlight, it achieves the purpose of preventing the spread of fire and delaying the expansion of the fire, and can effectively prevent the fire naturally caused by LED downlight.
Fireproof downlights produced by each downlight manufacturer are slightly different. Best fire rated downlights produced by KYDLED who add fire rated materials to each joint of the heat sink. In order to save costs, other downlight manufacturers only have a layer of fireproof material. This is not a fully qualified product in the market. So when you buy LED fire rated downlight for your home, don’t miss out on the real fireproof downlight that keeps your house safe because of the high price. Please look for best down lighting manufacturers and suppliers.
3. Why do LED Downlights Flicker?
If you eyes can see the LED downlight flicker, it proves that a part of the downlight is damaged. There are two main reasons for LED downlight flicker:
- LED chip is broken.
- LED driver is broken.
most of LED downlights are damaged due to LED driver.
How can we tell that is LED chip broken or LED driver broken?
The user can replace the flicker downlight with a non-flickering LED downlight power supply. If it does not flash after replacing it, it proves that the LED power supply is damaged. If it still flickers after replacing it, it is the cause of LED chips.
Regarding the cause of the damage to the LED chips, the welding wires of the LED chips are loose. The reason is that the temperature is too high. It reflects from the side that the heat sink is not enough or the power output current is too large. Of course, LED downlight has been used for a long time even exceeded its lifespan, this is also the reason for LED downlight flickering. While replacing LED chips, we need to measure the temperature of the radiator and the output current of the power supply to eliminate the two reasons for insufficient heat dissipation of the radiator and excessive output current of the power supply.
Regarding the reasons for the damage of LED driver, there are many reasons for LED driver, including the damage of freewheeling diode and the failure of capacitor of power supply. In this case, the only way to solve the problem is to replace LED driver.
As one of best recessed downlight manufacturers, KYDLED uses high-end materials to manufacture high-end downlights for you. We provide 2-5 years warranty for LED down lights. So buying LED downlights from LED downlights wholesalers of KYDLED worldwide, you will not worry about quality issues.
4. How do LED Downlights Work?
A light emitting diode is a solid-state semiconductor device. Driven by current, the LED can directly convert electrical energy into light.
LED downlight realizes illumination through the illuminated diodes. At present, there are two kinds of voltages for home lighting in the world, AC100-140V and AC220-240V. LED cannot work directly under AC100-140V and AC220-240V. They need to go through an AD/DC converter to convert AC to DC before driving the LED to emit light.
Of course, the LED downlight consists of a large number of LEDs fixed on an aluminum substrate to form a large light-emitting panel with positive and negative electrodes. We need to correspond DC positive pole output by downlight transformer to positive pole of LED light-emitting board, and DC negative pole output from converter to negative pole of LED light-emitting board. In this case, we connect LED downlight transformer to AC100-140V or AC220-240V voltage, and LED downlight can work normally.
5. How Many LED Downlights do I Need?
LED downlights are widely used in homes, shopping malls, offices, hotels, etc. For some newly renovated environments, many people do not know how many LED downlights they need. So how do we know how many LED downlights are needed? Below we judge from several aspects how many downlights we need for our homes, shopping malls, offices, hotels.
- What is the size of office or other venues for downlights we installed? How high is the office?
- what downlight wattage do we choose? What is the downlight lumens output?
- How much illuminance is needed at LED downlight installation space?
Let’s take the above 3 questions to give an example. For example, the area of shopping mall is 100 square meters and the height is 3 meters. We choose 15w LED downlight and the LED downlight lumens output is 1,350lm. Of cause, downlight ip44 is OK for mall. The illuminance of shopping mall is generally between 300-500lux and we choose the median value of 400lux. We use the simple algorithm formula Lux = ((Total Lumen) x 0.5)/ m². Bring the above parameters into corresponding positions, we can get 400lux=(1350*n*0.5)/100m², from which n=60, so we should use about 60pcs LED downlights for this mall.
If you cannot accurately calculate how many LED downlights you need. Please email our salesman. As the best LED downlight china manufacturer, we have professional designers and can give you a satisfactory design.
