Q:There are no holes 7 cm, 9W led downlight

Spotlights, 7 cm can do, and if you feel dazzling, you can use acrylic diffuser plate to do astigmatism, you can also adjust the angle

Q:What is the role of LED downlight

LED downlight effect:1, it can be embedded in the ceiling, will not affect the overall beauty, more concentrated than in the past ordinary lamps.2, in fact, choose a good day Lantern is a LED lamp energy saving function, long service life, good LED will not produce ultraviolet light.Is a lamp embedded into the lighting ceiling light shooting style. Is a directional lighting lamp, only its opposite to the light beam angle, belonging to the light, light is concentrated, contrasting. More prominent objects, higher lumen, more quiet.

Q:LED ceiling lamp and LED downlight what is the difference

The ground is the vertical light lamp, ceiling lamp is light.

Q:Home LED lighting downlight is broken, want to change themselves, I would like to ask how to remove ah? Where do you start?

This figure is LED lamp, with the outer edge of hand buckle lamp can be removed from the back lamp, and the lamp can be damaged when installing a new launch, as long as the lamp cup cup (two pin plug back) directly inserted into the can.

Q:LED is not only the benefits of downlight what harm?

The characteristics of LED lamp: overall unified and perfect to keep building decoration, without destroying the lamps installed, building decoration light hidden inside, the light source is not exposed, no glare, the visual effect is soft and uniformThe advantages of LED downlight:1, energy saving: white light LED energy consumption is only incandescent lamp 1/10, energy-saving lamps 2/5, longevity: LED theoretical life can be more than 100 thousand hours, for ordinary family lighting can be described as "once and for all"". LED downlight pictures (19)2, can work in a high-speed state: energy-saving lamps, if frequent start or turn off, the filament will blacken, quickly damaged.3, solid state package, belong to cold light source type. Therefore, it is easy to transport and install, can be installed in any micro and closed equipment, not afraid of vibration, the main consideration is the heat dissipation.4, LED lighting technology is changing rapidly, and its luminous efficiency is amazing breakthrough, the price is constantly decreasing. The era of a white LED lamp coming into the home is fast coming.5, environmental protection, without mercury (Hg) and other harmful substances to the environment, will not cause damage to the environment. The assembly parts of LED lights can be easily disassembled and disassembled, and can be recycled by other people without recycling by the manufacturer. LED does not contain infrared and ultraviolet light, so it does not attract insects.6 、 fast response speed: LED fast response, completely eliminates the shortcomings of the traditional high voltage sodium lamp glow process.To say LED downlight drawback is the market disruption of LED products are not up to the specified standard, so the market will have a lot of defects, and the price is low

Q:Turn off the lights after the bright LED lamp

Because the electrician is working on the power off switch, the power switch is a zero line, not a live wire. Electricians know that the power switch must be cut off by the line of fire, and no danger of electric shock is announced. If the power switch is on fire line, after the power is cut off, the FireWire will continue to supply power to the LED driver. Therefore, the LED lamp will have a faint light when the switch is turned off.

Q:How much is the general 15WLED lamp luminous flux.

Look at the product parameters, and if it's done with a single 1W, it's probably around 1600LM,

Q:The difference between ordinary LED lamp and LED downlight and integration of advantages and disadvantages

Integrated downlight features:1. strong anti glare than the old lamp;The 2. lamp body adopts integrated design;3. spring elasticity is more suitable for installation;4. new package 2835 beads, can provide high lumen output. Have completed the best quality lamp wafer chip package can provide high brightness output. In many applications, it is very suitable. The design is compatible with the element size, brightness and trust so as to make the design more uniform spot downlight;5. the design of fastener design and opening recognition has been increased in packaging, which improves the reliability of packaging and the convenience of installing holes.

Q:Led downlight and LED flat lamp that is durable

The same, but the shape is different, LED light plate and power module is the same

Q:Common questions about LED downlight spotlights

According to your lamp data should be 4W your dimming driver is 6--12, 12V4 is only 6W output power so only one use, otherwise affect dimming
