  ================================================== ================
[Concept]
    Downlight is embedded within the light beam ceiling lighting fixtures.
================================================== ================
【Introduction】
       Downlight with clear and dark-mounted equipment
       About the same surface mounted downlight is a lamp, but the downlights and concealed different, it is more decorative
       Downlights are generally large (5 inch) in (4 inch) Small (2.5 inch) three.
       Downlight with horizontal and vertical plug inserted two, horizontal price insert a little more expensive than the vertical interpolation.
       See the general location from the application are installed downlights in the ceiling, the ceiling needs to 150mm above general can install. Of course, there are external-type lamp. No dome light or chandelier in the area is a good choice installed downlights, spotlights to light as opposed to soft.
       Downlight Applications: large offices, conference rooms and shops, laboratories, airports and some of its civilian room.
================================================== ================
[Classification]
-----------------------
1, [according to installation]
    Recessed downlights and surface mounted downlights.
-----------------------
2, [according to lamp installation]
    Screw base lamp with plug, vertical and horizontal lamp downlights.
-----------------------
3, [by location]
    Downlight Downlight with home projects.
-----------------------
4, [according to the number of light]
    Single and double plug inserted Downlight Downlight.
-----------------------
5, [according to the fog light conditions]
    Ordinary lamp and fog lamp.
-----------------------
6, [according to the size of points]
    2 inches; 2.5 inches; 3 inches; 3.5 inches; 4 inches; 5,6,8,10 inch. Inches is inches, refers to the inside diameter of the reflector cup.
-----------------------
7, [according to source type]
    Ordinary lamp and LED lamp.
================================================== ================
【Material】
-----------------------
1, the average family with a maximum of not more than 2.5-inch downlight, put 5W energy saving lamps on the line.
-----------------------
2, LED Downlight is the latest-generation only, and can be used as a substitute for an ordinary lamp, the light than ordinary good, the only drawback is that if a bad light on the points 1, 2, can not be replaced.
 
-----------------------
3, Downlight Cover materials are also many different kinds, Iron Mask, aluminum, die-casting and other materials, in general, Impartial cheap downlight, die-cast aluminum and other materials are more expensive, but more durable. Projects with more than the lamp for the Iron Mask, but the downlights with recommended home improvement is not easy to cover surface rust.
-----------------------
       Lamp head is the more important aspect, head of the main material is ceramic. Inside the reed is the most important, there are copper and aluminum are two good brands of aluminum is used to do, and install a spring contact points, can enhance the contact. The other is the head of the power line, a good brand is the use of three-wire connection head (three lines that line of fire, spirit line, ground line), and some will bring the terminal, this is a good brand and differentiate the brand a very basic common method.
-----------------------
Reflective glass and optical glass cup of sand generally two types of material for aluminum, aluminum will not change color, and glare is better. Some manufacturers will use a small plastic spray to do, this new technology looks good, but over time will darken, or even black. Identification method is to look at the neat cutting degree, very neat cutting of aluminum, spray the opposite.
================================================== ================
[Characteristics]
-----------------------
1, compact and high-flux
        Incandescent lamps with energy-saving lamp power consumption is 1 / 5, life is six times incandescent, compact size designed to keep the 175, there is a sense of inhibition of the lamp, creating a bright space.
 
-----------------------
2, there are two mirror reflector and frosted
    Bring the mirror reflector of light flashes to a moderate degree of Hui to reconcile the ceiling matte type reflector.
-----------------------
3, using a sliding fixed cards, convenient
    3mm to 25mm can be installed in the ceiling of different thickness, maintenance of the lamps can be easily removed.
-----------------------
4, energy-saving lamps are available in three color temperature
       There 2700k (yellow), 4000k (neutral light), 6700k (white) of three types, three color temperature can create a different atmosphere. According to the different uses to select the most suitable color tube.
================================================== ================
[Security]
       The main problem lies in the lamp light on the mouth, and some brand-name lights downlight mouth not heat, deformation, resulting in light bulbs do not screw down. 3C certification by the consumer to choose the lamp. Another is the panel thickness is very important
================================================== ================
[The difference] spotlights and downlights
    Downlights and spotlights many people are confused, do not know what the two types of lamps are different, what is to be applied to the home position, and the application of the results are different.
-----------------------
       In short,
       Downlight is a clear mounted relative to the normal lighting of the lamp condenser is more generally used for general lighting or auxiliary illumination.
       Light is a highly concentrating the lamps, the light from it is a specific target can be specified. Mainly used for special lighting, such as stress or a lot of flavor is very new in the.
-----------------------
We distinguish between several aspects from downlights and spotlights.
1, can be loaded from the light source lamp to see incandescent bulbs, you can also install energy-saving lamps. When installed incandescent yellow. Installed energy-saving lamps as the bulb type can be white or yellow. Lamp light source direction can not be adjusted. General household lighting using a quartz bulb, or lamp beads. Of course, the spotlight is not necessarily a large quartz bulbs. Equipped with a quartz bulb is generally yellow. And general lighting of the light source direction can be adjusted freely.
 
-----------------------
2, generally from the application position to see downlights are installed in the ceiling, the ceiling is generally only need to be installed above 120mm. Of course, there are external-type lamp. No dome light or chandelier in the area is a good choice installed downlights, spotlights to light as opposed to soft.
Spotlights can generally be divided into orbital, point hanging and other embedded. Spotlights are generally of a transformer, but also without a transformer. The spotlights can be embedded in the ceiling mounted. Lighting used to emphasize or performance of the land, such as video walls, paintings, jewelry, etc., can play to enhance the effect of light rhyme.
-----------------------
3, the price point the same grade, spotlights expensive.
       Downlights are generally large (5 inch) in (4 inch) Small (2.5 inch) three. Downlight with horizontal and vertical plug inserted two, cross-price vertical plug inserted a little more expensive (but also of the same material).
It must be noted that the lighting is generally not used for brachytherapy wool fabric, it can not close a flammable obstacles, or easily cause a fire. Although the lighting power consumption and more, but have it in place decorative effect is quite different. There are five lights spotlights cup decorated tastefully.
