LED chips are very important: good LED chips, high light efficiency, low temperature rise, high color rendering index, high junction temperature, antistatic. Heat dissipation is very important: if you emphasize that the LED is a cold light source and does not need to dissipate heat, it is a complete mistake. Before the LED chip with a really low heat has not been developed, the LED does not have a high-quality heat sink, so its life may be far behind. The current ordinary energy-saving lamps! Because the light decays to 70% of the initial luminous flux, it has already identified the end of life of the LED energy-saving lamps. The power supply is very important: whether it has passed the high temperature and high humidity, whether it has passed the high voltage safety (UL), whether it has passed the electromagnetic compatibility (EMC/EMI), it is also a hard indicator, and also determines the real life of the LED energy saving lamp, wood In the barrel effect, the power supply may be the short board of the LED energy-saving lamp. The lampshade is very important: the lampshade is the secondary light distribution of the LED energy-saving lamp. The current one has a lampshade, a transparent lampshade, a frosted lampshade, a milky white lampshade, and a light diffusing lampshade. No lampshade and transparent lampshade, no secondary light distribution, visible LED, multi-LED is multi-light source, direct glare, and the object is illuminated. The frosted lampshade lights up to see the LED light source, and the object is partially faint. The milky white lampshade lights up and does not see the LED light source but the light transmittance is low. High-quality LED energy-saving lamps generally use light-diffusing materials. When the LED light reaches the lampshade, the light is diffused away. After lighting, the LED light source is not visible. The LED energy-saving lamp becomes a large light source, and the illuminated object is not faint, and the light is diffused. The type of lampshade generally has a light transmittance of more than 80%, and the effect is good.
