Information
Who is using high power LED bulb?
- industrial and mining enterprises and institutions users:
This type of user is mainly used in the workshop lighting, the workshop is usually high (at least more than four meters above), the lighting needs to be a single operating site, the illumination request is greater than 300lx, light color to near noon cold white (6400K) Usually in hardware, stamping, machining, injection, etc. to include site-based operating stations as a unit of large-scale devices, smelting workshop, lamp device location is usually above the equipment or operating site, the operating staff in the post operation moment is in the lights Under the continuous operation of the moment is usually more than 8 hours.
- Mall mall shops and supermarkets planning simple dining and leisure occasions User:
Such users are mainly used in the usual commercial lighting space, the same use in the relatively high level of relatively high space, light color to warm white (3000K) and neutral white (4000K) -based, the main light to restore the authenticity of goods or ambient air The position of the lamp is usually above the commodity pile head, the dining table or the passenger walkway, and the light is always lit for 12 hours.
- usually rural home users:
Mainly for the decoration of the house is not usually the main house house house lighting, usually a family about 1-4 high-power lights, light up to no more than 5 hours, light color to cool white (6400K), longevity , Bright enough, power and then reach the real intention of saving is the original intention of the user purchase.
 
 
What do they value
- must be bright enough: the user is to sell high-power intention is to deal with the "brightness" question, to be satisfied with the bright! In the "satisfactory light" under the premise of the most energy-saving way to reach;
- must be satisfied with the long use of longevity: from the user characteristics and the use of environmental considerations, the use of short life is not only short of the cost of the second procurement costs, more important is the high cost of repeated replacement of labor and in the replacement process The formation of a short time downtime, strikes, out of business and the impact of peripheral operations directly lost.
- must have a good luminous color: Although the user is included in the lights under the long-term operation of the operating personnel in addition to "bright" and "no light" is not clear "light" on how much damage, but as much as possible So that the light is close to the natural light is indeed the lighting business all the necessary social responsibility, especially for a long time in the lights under the collective operation of the more important.
 
 
How do we deal with it?
To the characteristics of the LED if the traditional lighting and light away from the concept of separation, only satisfied with the user "brightness, light color, longevity" needs, then it can play the imagination of space planning a wide range of lamps and LED light source integration of goods, But the small security had to consider changing models will be integrated with the light after the light source on the user is a demolition of the process of reloading, not only will add the cost of lighting will be added to the equipment and time to add the cost, so the priority A large number of stocks to replace the needs of shopping malls, small security first to self-rectification of the integration of light source as the prototype that is possible with the traditional energy-saving lamp shape structure, photoelectric color, device use methods close to the practice from another level also decided high-power LED Bulb sales unit price that can not be higher than the traditional high-quality three-color phosphor high-power energy-saving lamps a lot, therefore, Xiao An team clearly delineated in the traditional best quality without energy on the basis of cost, The effect is greater than 80Lm / W, color rendering index greater than 80Ra, R9 is greater than 30, the normal use of more than three years (10 hours per day operations ) And other hard technical indicators, small security contact appearance of goods structure, LED lamp beads, drives, radiators, through the mask, etc. launched a series of anti-repetitive research and experiments, such as:
- Outline construction
Has been determined in the direction of the traditional energy-saving lamps, then the shape, scale, size, including light-emitting surface can only make possible in the energy-saving lamp on the basis of optimization, it is necessary to co-ordinate the drive, radiator, lamp beads and transparent cover B100 Today's appearance Although a bit like "gourd doll", "bottle" appearance, but it is indeed a small security team entrusted professional industrial planning agencies twenty-one easy to learn after the fruition.
-LED lamp beads
LED lamp beads is the resolution of the product brightness, luminous color, luminous flux retention rate and the number of parts of the longevity, there is no LED lamp beads practice there is no LED lights say so, so can not pick a good lamp beads chip and packaging factory practice It is painstaking to learn from the chip scale, chip parameters to the stent, gold thread, glue, phosphor and packaging technology, etc., before and after the visit can be completed, the main elements of the "bright, light color, longevity" three elements of the main prerequisites More than a dozen factories concerned, repeated discussion of high-power lights may encounter bad use of the environment and restricted cooling space in the case of relatively high temperature how to prevent and eradicate the lamp beads early failure including early light failure question, in the package Including the chip factory with the full selection of special custom way, after nearly 1000 hours after the high temperature, low temperature and relying on the small multi-point probe active thermometer, thermal radiation tester, spectrometer, photometric spreader test test Techniques, the selection of a complete satisfaction B100 structure required double crystal 2835 / 0.5W high highlight LED lamp beads.
-driver
Although the lighting electronics is a small security team nearly two decades to proud of the central strengths, but taking into account the stability of high-power lights, reliability and the importance of longevity, but also based on power, poor heat dissipation of the objective practice, Xiao An team to cautious mood carefully selected including IC driver chip plan, electrolysis, transformers and other key components of the center of the supplier, the same B100 drive relying on small security contains high and low temperature active aging equipment, oscilloscope, drive input Output tester, multi-point probe active thermometer and other hardware practices, after 1000 hours of 242V high voltage, 80 degrees high temperature and minus 20 degrees under the conditions of low temperature repeated lights, impact verification.
-heat sink
Insiders are simply know that no matter how good the LED lamp beads when the negative temperature exceeds 100 degrees, its life and luminous flux retention rate is simply clouds. The The To deal with the lamp beads temperature In addition to looking for good, matching the thermal conductor is simply no other shortcut, and the best heat sink is the heat source that lamp beads negative temperature stability in the case of the difference between the conductor and the smaller the better. Xiaoan team from the B100 radiator raw material selection to the heat radiation area, up and down convection conduction, aluminum plate near the conduction (from the negative side of the aluminum plate about 1mm slotted convection), aluminum substrate and the radiator with the fit technology The The The After the B100 measured LED lamp beads negative temperature is not greater than 92 degrees (custom lamp beads agreed by the safety temperature), the thermal conductor surface temperature of about 75 degrees, that is, between the lamp heat source and heat sink between the two less than 20 degrees temperature difference Request and obtain a national patent.
- Transparent cover
PC, PMMA and other plastic-based light transmission materials in the LED instead of the traditional light source process has now been popular, indeed the plastic medium through the mask with the transport device in the process is not easy to break the advantages of materials and better plastic The reflectance of the mask in the integrated sphere spectrometer under the conditions of light transmission rate also reached more than 90%, has been close to the glass light transmittance. But the small security team according to high-power lights are usually four meters or even higher layers of high space, and therefore, the contrast and light intensity have a higher request, so the small security team in the standard darkroom with a distributed photometer to measure the illumination, accidentally found two A completely the same light transmittance of the plastic and glass cover the illumination of the different, forced the B100 decision to use a higher relative illumination, light penetration, light color clear glass through the mask, although Xiaoan know because the choice of fragile Of the glass cover will have to B100 packaging planning to bring high cost.
