If it is a small partner who has entered the field in recent years, it may be rare to see halogen track lights in China. According to the matching light source, there are several commonly used halogen track lights: lamp cup (MR16) type, aluminum cup type (also known as OR111 or AR111), PAR bubble type, QT32 type.
Advantages of Halogen track lights:
1, the lamp body is small, simple structure (lamp body + electrical + can be changed light source), cheap.
2, the color rendering is good, and the light sense has excellent brightness, so that the illuminated object emits luster.
Cons:
1, the heat is large, the light is sensitive to the illuminated object, the light needs to add special protection treatment.
2, high energy consumption, short life, for commercial space operation and maintenance, the cost of electricity and often need to replace the cost of the light source is very high, which is also the halogen track light in the 2010-2013 years by LED products quickly replaced and eliminated the most important reason.
PS: Now in the domestic commercial format, the application of halogen track lights has rarely been seen, and it is almost extinct. However, when I was on a business trip in Europe last year, I paid attention to local shops, and halogen track lights still accounted for a large proportion.
The product of track light using fluorescent light source is relatively rare, because the fluorescent light source is a large area of light, so it is difficult to achieve the key lighting effect. But for some special places, such as wall washing requirements, in the past when the optical program was not developed with leds, fluorescent lamps were the only choice, and H tubes were commonly used to combine the design into wall washing products, of course, due to the limitation of the light source, the past wall washing effect certainly could not be described in the same light as today.
Gold halide track light was once the early indoor business photo sales crown products, clothing chain stores, shopping malls, furniture showrooms and stores, it is the first choice, and the amount is huge, with the expansion of the brand store, gold halide light is really everywhere.
There are also different types of light sources for gold halide lamps, such as G12, G8.5, PAR30, PAR20, and so on.
Generally the same product, the manufacturer will design the version of CDM-T gold halide lamp and also design the PAR light source version, the PAR light source is E27 screw type, and the luminous Angle has been designed.
Gold halide lamps have several notable features:
1, high light efficiency, high power, is to create "is brighter than the competitive brand store next door" artifact!
2, long life, compared with the halogen light source that needs to be changed for an average of half a year, the life of the gold halogen lamp is enough for a decoration cycle of the store.
But it also has several hard injuries:
1. The gold halide lamp takes a long time to start, and needs cooling when restarting, and can not be turned off immediately after opening.
2, poor quality gold halide light source prone to color drift (with the color difference we are talking about now is still a little different)
3, the light efficiency is very high, the power selection is less (the conventional is 35W and 70W and 150W 3 kinds of power), does not support dimming, so it is difficult to achieve a variety of effects.
4, the electrical apparatus of the gold halide lamp is divided into two kinds of electronics and inductance, the inductance ballast is large, not beautiful, and the inductance is easy to have noise.
After experiencing the above three kinds of lighting products, at the beginning of the 21st century, LED has begun to emerge, in about 2006-2008, there are already companies began to try, after 2008, it is set off an intensive LED promotion, application, replacement tide. LED track lights have also undergone changes over the years.
The first LED track light: a replacement for halogen lamps.
At the beginning, the LED technology is not outstanding, color rendering, light efficiency can not be compared with today's products, but under the concept of energy saving and environmental protection, it is easy to accept this new product, but when the price is closed, it is prohibitive.
The earliest batch of LED track lights, manufacturers introduced more for the light frame with light source, there is no concept of integrated design of LED products.
Slowly, the technological progress of the upstream LED chip has been promoted to lighting application manufacturers, coupled with the introduction of foreign integrated LED products, and a new generation of LED track lights has made a shining debut. At this stage, LED track lights can be said to be a crazy growth era, and R & D engineers and quality testing are also facing great challenges.
On the one hand, the heat dissipation and optical design of LED is itself a less contact work for them in the past, requiring a lot of exploration and experimental testing.
On the other hand, the technology of LED is updated too fast, often a product has not yet been mass-produced, and the new light source has come out.
Returning to the application effect, the effect of LED track lights at this stage in terms of energy saving is actually not so significant, and the color is not good, but due to the intensive promotion of the market, customers are willing to try such new products and take it as the trend, and some of the larger chain brands are relatively cautious.
When the COB light source appears, the application manufacturers find that such a centralized package of small volume and high power LED new products, the product design is easier, and in the case of the same volume, the lamp can achieve more power to meet the needs of higher lumen value, is the most mainstream LED track light in modern commercial lighting space.
Of course, the optical design of COB orbital spotlights has undergone several changes, and there are several different types available on the market
Single reflection cup type (this class is also the earliest), reflective cup + light guide column type, lens type. Each has its own characteristics and advantages, such as the reflective cup type product utilization efficiency, the lens-type COB track spot light is relatively good, and the lens can be thinner, thereby reducing the length of the lamp body.
Main features of COB track spotlights:
1, the power range is large, there are 3W, 5W such small power products to meet the needs of restaurants, home space; There are 25, 35W such high-power products to meet the lighting needs of the store;
2, the color temperature range is wide, from 2400K, 2700K to 5000K, 6000K, the color temperature is diverse and customizable, breaking the color temperature limit of 3000K, 4000K, can meet the needs of more subdivisions;
3, color rendering also has better progress.
Cons:
1, COB light source products are difficult to achieve ultra-narrow Angle. Due to its large luminous surface, it is difficult to concentrate the light, generally speaking, the minimum Angle that COB type track spot light manufacturers can do is about 10° (except for individual museum grade products).
2, COB light source products are prone to secondary spots, and the spot cutoff line is tough. (Of course, it can also be eliminated by special optical treatment, such as adding an optimizer.)
Now the COB technology has advanced, can be applied in different segments, including a variety of different display places of application effect is also very good.
AC type no-drive LED track light, is the emergence of new products in recent years, in some applications and exhibitions abroad will see, there are also manufacturers in production, at this stage mostly export-oriented, less domestic applications, here is not much to say, you can pay more attention to interested.
About the track light, to expand, there are a lot of content to talk about, this article can only let you sort out a thought, later we will be extended to some problems. Of course, there is a special point to emphasize here, the first generation of the second generation in this article such a classification, only according to the time appeared sooner or later division, does not mean that the new product is better than the old product.
For example, a single light source type track spot light, due to its small luminous surface, has its irreplaceable advantages when doing high-end fine museum display lighting. The latest AC non-drive track light, whether it will be accepted by the public, also needs time to verify.
