Led spotlights definition


Led spotlights is the most concerned about the current energy-saving environmental protection products to LED as a light source made more and more lamps, one of the most acclaim is the LED lighting, because compared with other LED lamps, LED spotlights lower prices.

1. LED lighting using low-voltage direct current can be driven: with a small load, the advantages of weak interference, the use of lower environmental requirements. 2. LED lighting can better control the composition of the luminous spectrum, which can be well used in museums and exhibition hall in the local or key lighting.

3. LED lighting light-emitting point is very strong: brightness attenuation is much lower than the traditional light source, LED lighting prices civilians.

4. LED lighting response time is very fast: in the microsecond level, as long as the switch is open, immediately will be bright, there will be no delay and flashing phenomenon.

5. LED spotlights issued by the light energy concentration is high: concentrated in the smaller wavelength window, high purity.

6. Life is very long, generally between 50,000 to 100,000 hours, because the LED is a semiconductor device, even the frequent switch, it will not affect the service life.

7. Good environmental protection, LED lighting in the production process do not add "mercury", do not need to inflate, do not need glass shell, good impact resistance, good shock resistance, easy to break, easy to transport, very environmentally friendly, known as "Green energy", LED spotlight price of civilians.

8. Energy-saving, LED lighting, almost all of the spectrum focused on the visible light band, the luminous efficiency of up to 80 ~ 90%. Most people think that energy-saving lamps can be energy-saving 4/5 is a great initiative, but LED lighting than energy-saving lamps but also energy-saving 1/2, which is a great reform of solid light source.

In addition, LED lighting also has other advantages, high light quality, basically no radiation, LED spotlight price of civilians, are typical of green lighting; reliable and durable, maintenance costs are extremely low and so on. Because LED lighting has more than other solid light source can not match the characteristics of 10 years after the LED lighting industry will be the mainstream light source.

As the LED bulb in the structure than the halogen spotlights complex, so even in the case of large-scale production, the product price will be higher than the halogen lamp. But as more and more people know and accept, as well as the scale of the production slowly spread, LED lighting prices will soon reach the acceptable level. If you count on the purchase of an energy-saving account, you will find that even a higher price, in the use of a year on the basis of the initial purchase cost + 1 year electricity costs are lower than the traditional halogen spotlights. And LED bulb life has been up to 50,000 hours or more.

Classification editor

At this stage of the LED spotlights mainly to replace the traditional halogen-based, so the dimensions are reference to IEC 60630 standard, lamp reference IEC60061-1 standard. According to the traditional spotlights, LED spotlights are MR16, PAR16, PAR20, PAR30, PAR38 these kinds. PAR16 is mainly used GU5.3, E16 (Euclidean) / E27 (Europe and China), E14 lamp; PAR20 / PA30 / PAR38 mainly use E26, E27 lamp.

Structural features editor

Spot a wide range, used for manufacturing effects, embellishment atmosphere. Color is white, beige, light gray, gold, silver, black and other colors; shape long, round, size and size of different sizes. Because the shape of exquisite small, very decorative. So in general, more in a variety of combinations placed in a more decorative place, from the details of the owner reflects the exquisite life and unique taste. In the choice of weight in the shape of the grade and the resulting light and shadow effects, because it is a typical decorative lamps, the brightness level may not be too much to consider.

Spotlights can be placed in the ceiling around the top of the furniture, can also be placed in the wall, wall or skirting line.

1, energy: the same power LED lamp power consumption is only 10% of incandescent, but also energy saving than fluorescent.

2, long life: LED lamp beads can work 50,000 hours, longer than fluorescent and incandescent.

3, dimmable: the previous dimmer has been for incandescent, incandescent dimmed when the red light; it is difficult to see the fluorescent dimmer, which is dimmed technology for many years did not develop the main reason; And can be dimmed, and whether it is bright or dark light are the same color (color temperature basically unchanged), which is significantly better than incandescent dimming.

4, can be frequent switch: LED life is calculated by lighting, even if the switch thousands of times per second does not affect the LED life, in the decoration and other needs of frequent occasions off, LED lights have an absolute advantage.

5, rich colors: there are white, warm white, red, green, blue and other colors, whether it is used in the living room under the lights for small lights or neon lights, are very bright.

6, low heat: like spotlights, a lot of 220V spotlights with a few days is not broken because of fever. 12V halogen spotlights heat less than 220V spotlights, but there are due to lack of power transformer and other reasons, its brightness can not reach the nominal value. With LED lighting, no transformer can work for a long time.

Structure composition editing

LED spotlights mainly by the shell, lamp beads, aluminum plate, drive composition, the specific analysis is as follows:

LED lighting shell: paint, plating two shell package, including lamp cover, lamp cup, base, aluminum plate, lens, screw for MR16, GU10 lotus-like, beautiful, generous heat dissipation.

Spotlights low pressure, high pressure two, consumers choose the best low-voltage spotlights, its long life, light efficiency higher. The luminous efficiency of the spotlight is characterized by the power factor, the greater the power factor is, the better the power factor of the ordinary spotlight is about 0.5, the price is high, the power factor of the high quality spotlight can reach 0.99, the price is slightly expensive.

Spotlights are generally used to enhance the lighting on the ornaments, usually embedded in the ceiling or wall, the spotlight work will generally issue a higher temperature, so be sure to buy high-quality products, or there will be security risks.

Spotlights to use with the use of transformers, light beads should also choose good quality, or light bulb lamp beads is easy to bad, think about the ceiling of the spotlights lamp beads, but it is quite troublesome to replace.

The quality of the spotlights on the market varies greatly, with the naked eye is difficult to distinguish between good and bad, so buy the best choice for brand products, and choose to match the quality of the transformer.

Differences in editing

Many people are not easy to distinguish between downlight and spotlights, in the home decoration, downlight and spotlights have different uses, simply said, downlight is a relative to the ordinary lighting fixtures more condenser, Generally used for general lighting or auxiliary lighting. Spotlight is a highly condensed lamp, its light exposure is able to specify a specific target. Mainly for special lighting, such as emphasizing a very tasteful or very innovative place. We from the light source, the application location, and the price comparison to distinguish between the two characteristics of the lamp.

1, light source

Downlight can be installed incandescent bulbs, can also be installed energy-saving lamps. When installed incandescent lamp is yellow, installed energy-saving lamps when the light bulb type can be white or yellow. The direction of the light source of the ceiling light can not be adjusted. We can directly see the downlight of the energy-saving lamp, and waterproof downlight is added to the outside of a waterproof glass cover.

General household lighting with a quartz light bulb, or lamp beads. Of course, large spotlights are not necessarily made of quartz bulbs. The quartz bulb is only yellow. And the general direction of the light source can be adjusted freely.

2, the application location

Downlights are generally installed in the ceiling, the general ceiling need to be installed in more than 150mm. Of course, downlight also has an external type. It is a good choice to install a downlight in an area without a dome or chandelier, and the light is softer relative to the spotlight.

Spotlights can generally be divided into track, point hanging and embedded and other kinds. Spotlights generally with a transformer, but also with no transformer. Built-in spotlights can be installed in the ceiling. Spotlights are mainly used for places that need to be emphasized or expressed. Such as TV wall, paintings, jewelry, etc., you can play the rhyme to enhance the effect.

3, the price

Downlights are generally large (5 inch) (4 inch) small (2.5 inch) three. Small market price between 15-20 yuan, medium 28-32 yuan between the large between 36-48 yuan. Of course, the above prices do not contain light source. Downlight has horizontal and vertical insert two, cross inserted the price than the vertical insert a little expensive.

It should be noted that the spotlights generally can not be used for close exposure of wool fabric, can not be close to the flammable obstacles, or easy to cause a fire. Although the spotlight power consumption, but in the appropriate location it has a very different embellishment effect. There are colorful lights and decorative lights do not have the flavor.

Install edits

1, the process:

Lighthouse, lighting installation → with the next line off → test lights

2, lighthouse, lighting installation:

1) according to the design requirements measured lamp (lighthouse) installation height, in the poles on the mark.

2) the lighthouse, lamps hanging pole (heavier lighthouse, lamps can use pulleys, rope hanging pole), put on hoop or bolts, according to the design requirements to find a good angle of exposure, After the lighthouse is fastened.

3) into the row of installed lamps its elevation should be consistent, neatly arranged.

3, with the lead off the assembly line: the needle insulator fixed on the lighthouse, the end of the wire tied on the insulator back, and were with the lamp line, the fuse to connect. Rubber cloth and black rubber cloth half a layer of each layer. Then, tighten the other end of the wire and wrap it with the trunk of the street.

4, the phase of the lamp should be equipped with a fuse, and the phase line should be screwed to the center of the lamp terminal.

5, line and street light connection point from the center of the rod should be 400 ~ 600mm, and symmetrical on both sides.

6, lead off the wharf should not have joints, the length should not exceed 4m, should be added when the fixed point or the use of steel pipe lead.

7, the wire into the lighthouse should be set at the soft plastic pipe, and do waterproof bend.

8, test light: all the installation work is completed, power, test lights, and further adjust the lighting angle of the lamp.
