How To Choose Mobile Light Tower?（Different Lamps Comparison）
Today’s topic is mobile lighting tower. Through the following content, you will be able to understand clearly what is a mobile lighting tower? What light sources are in the mobile lighting towers? What are the differences between them(different lamps)?
We will see the advantage of mobile light towers based on the comparion with the traditional lighting method. Firstly, what are the disadvantages of traditional lighting? The traditional wiring method of construction site lighting not only requires a power generation device, but also needs to buy a long wire for connection. In some places, a bracket is required to support it for lighting, which is not only cumbersome but also has potential safety hazards. Then we will find the advantages of the mobile light towers. The mobile lighting group can adjust and rotate each lamp head individually to achieve 360° omnidirectional lighting according to the needs of the site; Lighting in the same direction, the light panel can be turned over within 250° to the opening direction as a whole according to the required lighting angle and orientation, and rotated 360° to the left and right with the mast as the axis.
Except this, mobile light towers are widely used in many situations, and the light sources used in different configuration types of mobile lighting towers are different. Common lamps include xenon lamps, mercury lamps, and metal halide lamps and LED lamps. In these four lamps, mercury lamp, xenon and metal halide lamps are gas discharge lamps and three different lamps. There are certain differences in performance characteristics. The following Jingquan lighting mobile lighting manufacturers will take you to understand the differences between these three lamps in detail.
First, through the definitions of xenon lamps, mercury lamps, and metal halide lamps, roughly distinguish xenon lamps, mercury lamps, and metal halide lamps.
The general English abbreviation of xenon lamp is HID Xenon Lamps, and the lighting is a cold light source.
Mercury lamps, metal halide lamps are generally referred to as HID Lamps in English, and the lighting is a warm light source.
You can clearly see the xenon lamp and the mercury lamp. One of the differences between the metal halide lamp is that the xenon lamp arc tube is filled with xenon gas, while the mercury lamp and the metal halide lamp generally do not have xenon gas. The price is generally more expensive. Therefore, the price of xenon lamps is generally much higher than that of metal halide lamps and mercury lamps.
Secondly, the xenon lamp can be turned on immediately, not only cold start, but also hot start. Therefore, it can be used as a car headlight, but the starting of the xenon lamp requires a high pulse voltage, usually 12000V. Therefore, the price of the ballast for xenon lamps is generally more expensive.
For metal halide lamps and mercury lamps, only cold start, not hot start. That is to say, if you turn off the lighted metal halide lamp or mercury lamp, you must wait another 5-10 minutes before you can light it again. Therefore, they are generally used for commercial lighting such as square lighting and street lighting. For metal halide lamps, only a pulse voltage of 3000-4000V can be started. For mercury lamps, no trigger is required, and a voltage of 220V can be started.
Finally, let’s talk about the difference between mercury lamps and metal halide lamps. The difference between the two is that metal halide lamps have pills, while mercury lamps do not. Therefore, the luminous efficiency of metal halide lamps is high, and there are many kinds of color temperatures, ranging from 3000k to 20000k, but mercury lamps can only have one color temperature, about 4000k, because the arc tube does not have pills, but the common point of the three is that All belong to gas discharge lamps.
The above is the use of the light source of the mobile lighting group. Different light sources are suitable for different scenarios, so we must distinguish them clearly when purchasing, so as to avoid the poor use effect caused by the wrong selection. Considering the price and lighting effect, we chose metal halide lamp for our mobile light towers among the three lamps.
However, LED lamps is our main choice and more polular than metal halide lamps.
What are the purchasing skills of high-power LED lighting fixtures? In various commercial lighting projects, high-power LED lighting fixtures represented by LED downlights are always in considerable demand. High-power LED lamps are a kind of LED lighting lamps. Take LED downlights as an example. Compared with low-power LED downlights, high-power LED downlights have higher single power, brighter brightness and higher prices. Of course, because the high-power LED downlight itself has many parameters, there will be different classification standards according to different parameters. We will take you to see what are the purchasing skills of high-power LED lighting fixtures?
- Light quality and anti-glare effect.
Light quality is the soul of a lamp, and whether the spot produced is beautiful or not will directly affect the effect. The pros and cons of anti-glare performance are also critical.
- Look at the light efficiency.
The same lamp bead power, the higher the light efficiency, the higher the brightness, the same lighting brightness, the lower the power consumption, the more energy-saving.
- Look at the color temperature.
Whether the color temperature distribution is uniform will directly affect the lighting effect; and the color temperature and the color rendering index are related to each other, and the change of the color temperature will cause the change of the color rendering index.
- Look at the power efficiency.
The higher the power efficiency, the better, the higher the power, the smaller the power consumption of the power supply itself, and the greater the output power.
- Power factor of LED lamps.
The low power factor indicates that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the lamps. The process of die casting and cold forging is a more ideal choice at present.
- The heat dissipation performance of LED lamps.
The lower the thermal resistance, the better the heat dissipation. If the thermal resistance is high, the heat dissipation will be poor, so that the temperature of the device will increase, which will affect the wavelength shift of light. When the temperature rises by one degree, the wavelength of light will drift by 0.2-0.3nm, which will directly affect the quality of the light. Excessive temperature rise also directly affects the service life of high-power LED downlights.
- Look at the material and structure of the heat dissipation conditions of the lamps.
The heat dissipation of high-power lamps is also very important. The lamps with the same power factor and the lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads will work at high temperatures, and the light decay will be very large. Lamp life will be reduced.
- Whether the workmanship of LED lamps is fine.
A high-power LED lamp with good quality, in addition to the main aspects mentioned above, also has different technical requirements according to different use environments, such as moisture-proof, dust-proof, etc. , this parameter can be known from its IP protection level.
- Look at the quality of LED lamps and lanterns.
The quality of lamp beads depends on chip quality and packaging technology.
To sum up, what are the purchasing skills of high-power LED lighting fixtures? When using high-power LED lighting fixtures, you must understand light intensity distribution, color temperature distribution, thermal resistance and color rendering to master W-class high-power LED energy-saving lamps. About this, POWERSUM make it, we choose the suitable lamps for our light towers based on aboving all considerations. High-power LED lighting complies with the development trend of commercial lighting needs, so it can gain the favor of our customers, same as the mobile LED light towers.
