Dried food Feasibility analysis of using LED lamp to replace metal halide lamp

1 the name of the name of the golden halogen lamp

We know that Holland PHILPS is the inventor of the fluorescent lamp, the fluorescent lamp is the use of electron beam to strike the mercury vapor generated by ultraviolet light and then on the phosphor to produce visible light. In the future, the so-called energy-saving lamp is actually the fluorescent lamp to do fine, bending and electronic ballasts and integration. They also made on the basis of fluorescent lamps, high pressure mercury lamp, in the past called mercury lamp, is often used to take pictures of the film. Later we all know mercury is highly toxic, they will no longer be called mercury lamp, and because of the mixed halogen compounds, should actually be called mercury halogen lamps (Mercury Halide Lamp), but PHILPS called Metal Halide Lamp, used to replace metal mercury, and to China again the metal is simplified into gold is the name of the metal halide lamp, but there are not only a little gold, and silver, but unfortunately is not silver, but mercury! These big companies that China people's ability to flicker is really Nothing is too strange!

2 metal halide lamp specifications

PHILPS's metal halide lamp has the following specifications:

PAR20 35W 942, PAR20 35W 830, PAR30 35W 942, PAR30 35W 830, PAR30 70W 942, PAR30 70W 830.

Where 35W is the nominal power, and the actual power of 39W, 70W is a nominal power, the actual power of 73W.

942 and 830 is the difference in color temperature, the color coordinates of x=371, y=366, and 830 x=433, y=402,

In fact, 942 is 4200K, and the 830 is 3000K.

3 metal halide lamp size and angle

The shape of the metal halide lamp:

Although the metal halide lamp and PAR30 lamp using PAR20 name, but it is very different in size and PAR lamp, mainly because of its length (because of a high pressure mercury lamp itself needs a certain length of discharge, but the diameter) and PAR lamp the same.

The light beam its angle three, 26 degrees, 34 degrees and 70 degrees.

4 price of metal halide lamps

At present, the price can be found on the Internet Alibaba, the above specifications of the price of PHILPS gold halogen lamps are the same, are 125 yuan a (without ballast). But the price of domestic gold halogen lamp is uneven. For example, 70W metal halide lamp light rail type TLH301 NVC, charged sense of ballast and track lighting system, the price of 240 yuan. As shown in the following figure:

Ya Ming, Shanghai, with a ballast metal halide lamp, 250W 299 yuan, 400W of $325. Shape as shown below:

Non brand new bright spot in Changzhou 1000W metal halide lamp, if the price of 850 yuan Ya Ming gold halogen lamp, if the use of PHILPS's 1000W halogen lamp, priced at $1200, its appearance as follows:

5 the performance of metal halide lamp

Although most of the metal halide lamp is 70W gold halogen lamps, which are used by ordinary businesses. In addition, there is a greater power of the metal halide lamp is mainly industrial lamps. Their performance indicators are as follows:

150W below E27 lamp holder, above E40 lamp holder

Color temperature: 4500K

Lumen: 1000 W, 80000 lumens (PHILPS)

Light effect: because the metal halide lamp is usually 360 degrees of light, in the vertical installation, there are a lot of light is blocked, so the whole lighting effect is very low

Life: 30000 hours, 6 hours a day, you can point to 10 years

IP65

Gold halogen lamp bulb shell temperature is very high, because of its luminous efficiency is not affected by temperature, so in order to improve the bubble shell temperature, with quartz instead of glass. Later, the use of transparent ceramics instead of quartz.

In fact, the biggest disadvantage of metal halide lamps in addition to mercury than need ballast, because of its great starting current is more than 15A, but also need to start a high voltage, so it is the most commonly used as a fluorescent lamp and the large inductance, but in this way the power factor PF and its value is very low, about 0.5. If you want a high PF, you must use a better performance, but more expensive electronic ballasts. Ordinary inductance ballast price of 65 yuan, the price of energy-saving inductance ballast is $80. The price of electronic ballasts will be hundreds of dollars.

Comparison of 6 and LED lamps

Although LED has many advantages, but for now, most of them can only replace the following 150W halogen lamp, as to replace the 400W to 1000W metal halide lamp LED lamp must use a large water cooling cycle of the radiator.

7 production and market of metal halide lamps

From 1999 to 2004, the output of the metal halide lamp is shown in the following figure:

Unit: 10000 only

Production of metal halide lamps in China

From 18 million 420 thousand in 1999 to the 2004 of only 2 million.

According to the 2007 estimate that within the next three years, metal halide lamp sales will reach 41 million 500 thousand units, the total sales of more than 8 billion 700 million, of which the share of electronic metal halide lamp at least 20%, the sale of 8 million 300 thousand lanterns, sales of 1 billion 540 million yuan. According to preliminary statistics, the metal halide lamp manufacturers 07 years of domestic strength is less than 50, mainly in Guangdong, Zhejiang, Jiangsu, Shanghai, Beijing and other regions, the main production enterprises have PHILPS, OSRAM, GE, FSL, Pulos Ya Ming, Shanghai Jiangsu, Foshan HuaQuan lighting etc..

2009 halogen halogen lamp production has reached 45 million, and the annual rate of increase of 15-20%.

According to China Association forecast 2010 annuity halogen lamp output was 5000
