The Low Output LED MR16 light bulb designed as a direct replacement for a halogen GU5.3/MR16 lamp uses only 1.8w to 3 watts of electricity equivalent to a 15w to 35w halogen bulb. Each lamp emits a low level of light perfectly suited to creating decorative, atmospheric and mood spotlighting in a variety of applications in the home, retail and hospitality industries as well as in museums and galleries. This is a low voltage light bulb available in a choice of Warm White, White and Daylight colour temperatures that offers all the advantages of LED lighting technology.

Switching a standard halogen MR16 light bulb for the LED alternative promptly reduces your energy consumption by 80%. Additionally these lamps offer an average lamp life of up to 50,000 hours minimizing lamp replacement costs. Because LED lamps run at a cool temperature they emit virtually no heat into the atmosphere; add to this the ‘no mercury content’ of these lamps and you have a reliable, high quality, environmentally friendly and energy efficient lighting solution.

LED product should pay attention to the problem

LED products in the processing and production process should take anti-static measures, such as: table to the ground, workers wear anti-static clothing, anti-static belt loop, as well as with anti-static gloves, conditions can install anti-static ion fan, while ensuring workshop humidity around 65%, so the air is too dry to produce static electricity, especially the green LED easily damaged by static. In addition, different quality grades of LED antistatic ability is not the same, the quality of high grade LED antistatic ability is stronger.

LED product should pay attention to the problem

In order to reduce product cost, Some manufacturers use “RC Buck” approach to power LED products, this will directly affect the life of LED products. Should be used for switching power supply (preferably a constant current source) to power LED products, so it will not affect the service life of the product.

When the ambient temperature rises, LED light resistance will be reduced, if the use of a regulated power supply will cause the LED current increases, when more than its rated operating current, it will affect the life of LED products will be serious LED light source, “burn” and therefore should be used in constant current power supply to ensure that LED current is not affected by the outside temperature.

LED products are often used in outdoor, also facing waterproof, moisture-proof sealing problems if not properly handled will directly affect the life of LED products. Some products require a relatively high quality traditional epoxy manufacturer “watering” approach to sealing LED products, this method operate more trouble, for the larger volume of LED products (such as LED guardrail lamps) is not very suitable , will cause an increase in product weight.

LED guardrail lamps before the most widely used control technology is “Serial Communications” approach. The advantage is that each guardrail lamps no specific “code”, can be arbitrarily between each exchange, to facilitate the production and installation works. But its biggest drawback is that if there is a damage, it will directly affect all the lights behind it, for hundreds or even thousands of meters of fence light engineering, due to the impact of external factors and the quality of the product itself and other factors, it is difficult to ensure that every a guardrail lights are not a problem, so a fence light problems that paralyzed part of the guardrail lamps.

Reasons for the Low Reliability of LED Driver

Although LED has high luminous efficiency, but still only a small part of the energy radiated in the form of light, most of the remaining energy is consumed in the form of heat inside the LED, therefore the LED light source itself seriously fever. The main reasons for the low reliability of LED driver in LED are as follows:

Reasons for the Low Reliability of LED Driver

　　First, close to a heat source.

Although higher luminous efficiency LED, but still flows through the LED energy can see only a small part of the energy radiated in the form of light, most of the remaining energy is consumed in the form of heat in the LED, the LED light source itself serious fever. LED drivers are usually placed inside the lamp, near the LED light source, only the temperature at 20-30 ℃ temperature environment, the ambient temperature around the driver can easily reach 50-60 ℃, at such a high temperature environment, to ensure the drive reliability, design (especially efficiency indicators) great challenge.

　Second, work at full capacity for a long time.

Without dimming LED driver is close to full capacity, while the vast majority of applications in switching power supply, such as computer power supply (adapter), communication power supply, and household appliances, with an average power of long-term work is usually only rated power a fraction of all the loads are turned on full power state only appears a few times in a particular.

Third, for outdoor lighting applications like in roads, squares, etc., it is vulnerable to external damage of natural phenomena such as thunder strike. All these will result in ongoing maintenance and other ills of large-scale application of LED semiconductor lighting.
