Question 6: How to evaluate whether an energy-saving lamp plastic part is resistant to high temperature and flame retardant? Our current energy-saving plastic parts are generally made of PBT material. Its chemical name is polybuty leneterepthalate. It is a kind of hot plastic. Generally, 10%~30% of glass fiber is added to it to get satisfactory heat. Deformation function, it can not deform for a long time at normal temperature of 180 ° C, and has good flame retardant and anti-ultraviolet radiation performance. Our simplest and straightforward way to test its temperature and flame retardancy is to use a lighter to burn it. If it is not easy to burn during burning, there is no liquid flow in the burning process. When the lighter leaves the plastic, it should be 5 seconds. After the clock is extinguished, we can basically conclude that it is a PBT material (although PC materials also have this property, but the cost of PC materials is higher, no one will do the product like this). ABS plastic is generally easier to burn than PBT plastic. It will continue to burn when the fire machine leaves after burning, but ABS is also flame retardant, but the flame retardant ABS plastic will have liquid substance drops when it burns. Come down. Question 7: Why does the energy-saving lamp plastic turn yellow when it is ignited for a while? Plastic yellowing is a basic characteristic of plastics. There are many reasons for yellowing of plastics, but one of the most important reasons is the influence of ultraviolet rays. PBT materials are no exception. Because of the process of lighting, ultraviolet rays are generated in the lamps. Ultraviolet radiation plastic makes it yellow. Of course, we can add some anti-UV material in the plastic, but this only extends the time it turns yellow. It will turn yellow after a long time. However, the yellowing of plastic does not affect some of the basic properties of plastics such as high temperature resistance and flame retardancy. Question 8: How to judge whether an energy-saving lamp has its components combined firmly? Since there is no special instrument like the laboratory in real life, we can only judge from the naked eye and some simple actions to judge and identify. When we judge the firmness of the combination of the lamp cap and the plastic part, we can first see whether there is a gap between the lamp cap and the plastic part with the eye, whether the gap size is reasonable, the hole of the lamp head is shallow, and then we hold the lamp cap with one hand. Hold the plastic piece with one hand and screw it by hand. If it can be unscrewed, the combination of the lamp head is not firm. When we judge the degree of firmness between the lamp and the plastic parts and the upper and lower plastic parts, we can also observe with the eyes first, then hold the upper and lower sides of them by hand, gently shake and pull with the hand, this force can not Too big, not too small, to see if they are loose. Question 9: How to judge the color rendering index of energy-saving lamps? We can light the lamp and shine it on our own palm. The palm is ruddy and bloody, indicating that the product has a high color rendering index. Similarly, if the color rendering index is low, the palm is blue and bloodless. We can also put a colored object under different lights to compare your feeling of color, and how you feel the color of the same object under the sun, or you can break the color rendering index of a lamp. . Question 10: Judging the luminous flux and luminous efficacy of energy-saving lamps? Judging whether an energy-saving lamp is energy-saving, is the energy-saving effect obvious? In the absence of instruments, we can only rely on the eyes to feel that it is not bright, if there is a comparison Better, you can light up the same-power energy-saving lamps to see how bright they are (of course one of them thinks that the quality is better, the price is higher, the other is bad quality, the price is cheap), good energy saving The brightness of the lamp product is very high, and you may even feel a glare. The poor energy-saving lamp is like a candlelight, or like a T12 fluorescent tube, even worse. Problem 11: Application of high-power energy-saving lamps in actual lighting Power-saving lamps will extend the lighting application technology of low-power energy-saving lamps from indoor small-scale lighting applications to a wide range of indoor and outdoor lighting applications. This is a breakthrough. Is an application technology innovation.
