Q: The office, sample room, corridor, the most commonly used several LED downlight which is several dimensions, what is power?: You should use big ones. My home is small, 5W's PL*D005

Q: LED is not only the benefits of downlight what harm?: And before the benefits of lighting equipment is quite obvious, if you really find faults if I feel bad replacement replacement, light bulb was down for a new can, to LED welding, when the current had a high fever bad replacement is more trouble, but because the LED lamp from the battery or the charging the battery power supply, basically there is no current unstable situation

Q: What is the difference between the LED and the LED lamp ceiling lamp: In appearance, it's just a different shape.If from the use point of view, led ceiling lamp has environmental protection, pollution-free, less power consumption, high light efficiency, long life and so on, it is widely used in urban road lighting.LED downlight belongs to directional lighting lamps', it only on the 'vertical' surface to the light beam angle belongs to light, light is concentrated, contrasting. More prominent objects, higher lumen, but also set off a quiet atmosphere of the environment.Led downlight characteristics: architectural decoration of the whole system and a 'perfect' does not break bad lighting settings, light hidden building interior decoration, the light source is not exposed, no glare, the visual effect is soft and uniform.

Q: The difference between ordinary LED lamp and LED downlight and integration of advantages and disadvantages: Fast response speed: LED fast response, completely eliminates the shortcomings of traditional high voltage sodium lamp glow process.However, we are called integrated downlight is not really "integration, although has been done in the" light "and" light body "development, but also the driving power. The general driving power supply is an external electric box, because of the larger size, the insulation shell and packaging will increase the cost.

Q: How much is the general 15WLED lamp luminous flux.: Usually around 1200lm. Warm colors will be low, cool colors will be high.

Q: What is the size LED downlight: LED lamp size generally have 6 inch, 5 inch, 4 inch, 3 inch, 2.5 inch, inch inch refers to here, refers to the inside of the reflection cup diameter.The commonly used standard size and parameters of LED downlight:2.5 inch LED lamp size parameters of hole (phi 80) - page table size Phi 102 * H30 power 3W;3 inch LED lamp size parameters of hole (phi 90) - page table size Phi 112 * H30 power 5W;3.5 inch LED lamp size parameters of hole (phi 100) - page table size Phi 122 * H30 power 7W;4 inch LED lamp size parameters of hole (phi 120) - page table size Phi 146 * H30 power 9W;5 inch LED lamp size parameters of hole (phi 150) - page table size Phi 180 * H30 power 12W;6 inch LED lamp size parameters of hole (phi 160) - page table size Phi 190 * H30 power 15W;LED downlight is a kind of embedded lighting ceiling light shooting style.

Q: Why use LED lamp light source patch: SMD LED light emitting angle is 180 degrees (theoretical value), the diffuse reflective light through the tubular lamp cup, directed and no lens dazzling, very suitable for general lighting purposes. Of course, the cost of the lens is also saved.

Q: LED downlight, embedded lamps, lamp tube and difference?: I. definitions1, downlightThe lamp is generally a lamp holder, lamp can be directly mounted incandescent or energy-saving lamps. Is a lamp embedded into the lighting ceiling light shooting style. Its biggest characteristic is to maintain the overall unity and perfection of the building decoration, not because of the setting of lamps and lanterns, and destroy the perfect unity of ceiling art. The recessed luminaire, mounted inside the ceiling, projects all the light downward, directly to the light. Different light effects can be obtained with different reflectors, lenses, louvers, and light bulbs. Table space, can increase the space of the soft atmosphere, if you want to create a warm feeling, can try a lamp lamp, reducing the spatial sense of oppression. Generally in the hotel, family, coffee shop use more.
