LED lighting technical standards

First, led light source: must use high-brightness, high light efficiency, low light loss led chip package, which would choose to use brand chip makers such as the United States Puri/Taiwan wafer yuan/Taiwan Guanghong and other brands of formal channel chip package led lamp beads, package The gold wire/phosphor/insulative glue etc. all need to meet the requirement material.

Second, the driving power: led is the DC electronic energy conversion semiconductor components, so a stable drive requires a high-performance power driver chip, while the power factor pu compensation function is needed to ensure power efficiency, the power supply to the entire lighting up Relevant important factors, and currently on the market led power quality uneven, mixed fish and dragon, good drive power is not only to ensure a stable DC supply, but also fully guarantee the improvement of conversion efficiency, this parameter reflects the lamp The true energy efficiency and no waste of the grid.

Third, the appearance of the structure of the cooling system, an excellent lighting in addition to the appearance of high-end, high-quality light source and power supply, but also more important is the rationality of the structure of the shell, which involves the cooling problem of led lamps, due to LED conversion light energy At the same time, there is also a part of the electrical energy into heat, it is necessary to lead the heat out to the air, so as to ensure that the led stable light, high temperature of the led lamp will cause light decay to accelerate the life of the led lamp. It is worth mentioning that the technology of LED chip is constantly improving, and the conversion efficiency is also improved. The amount of electricity used to convert heat will be less. The radiator parts will be used more thinly. It will also be used to reduce the cost, which is beneficial to the promotion of LED. This is just a direction of technological development. At present, the heat dissipation of the enclosure is still a parameter that must be considered.

Fourth, LED light lens is also often ignored by some designers, in fact, the refraction of light will produce light loss, the lens lens rate also affects the final output of the light flux, the current transmittance of the lens can reach more than 93 Since the lens is also a relatively important cost, some manufacturers use cheaper lens materials to save costs. It is definitely a secondary material. The light transmittance is about 70. It will not be obvious to the consumer to deceive consumers, but its practical instruments It is easy to test the results, the lens of poor material, with a long time will be yellow and other undesirable results.
