How to view the appearance issues of LED lighting lens
After the production of LED lenses, sometimes they may have some defects due to various reasons. And some defects can be seen on the appearance, so how to look at the defects on the appearance of LED lenses? Point defect: A defect with a point shape, and quality inspectors should use the maximum diameter as the standard for measuring. If there are discolored spots, bubbles, pits, oil stains and other adverse phenomena.
How to improve the quality management of LED lenses
Quality is the task of the company, and every employee seems to be familiar with this statement. But why quality is a company's application, perhaps many people do not have a realistic understanding. Why is the quality of our LED lenses declining? Why do we have many problems with the LED lenses we produce and our customers are becoming increasingly dissatisfied with us? First of all, it is not enough to attach importance, as the two often fall vic
LED lens refers to a spotlight that uses a light emitting diode as the light source. Traditional spotlights often use halogen lamps, which have high luminous power, low power consumption, high working temperature when exposed to direct sunlight, and short service life. LED lenses are far superior to traditional lighting products in terms of basic principles of illumination, environmental protection, energy conservation, and environmental protection. And the unidirectionality of LED lens illumination creates an extreme applicabil
