Select lighting lighting design is an important factor in the outcome of the performance, along with innovative LED illumination lighting technology is developing rapidly, and some laboratory month more next-generation products, LED lighting, mainly in: long life, small thermal radiation is small, energy-saving and environmental protection, the band long and so on.
First of all, from the outside appearance of the judge
A qualified product must be reasonable structure, surface treatment, delicate and various structural and functional components match, a complete clear product labels, lamps dimensions conform to the use of visual space scales, including packaging and product manual.
Then, the light source
Due to technical constraints and now most of the high-quality light source with the United States, Japan, Taiwan and the feedback is good. Different quality LED chip is the key difference between life, color temperature, light effects, and of course beam angle control. In the case of high-quality off the light source is more difficult to distinguish visually, often require technical specifications provided by the manufacturer.
Secondly, power supply
Many people drive power than a man's heart, enough to reflect its main character. First factory audit indicated parameters, because the LED voltage characteristics with a negative temperature coefficient characteristics, so it is not fixed, it varies with temperature. The main parameter analysis: input voltage, output voltage, output current, output power, power factor, wiring label, temperature, whether with overvoltage protection, overcurrent protection, and so on.
Next, heat treatment
LED is more sensitive to temperature, also spoke in front of a negative temperature coefficient, it is necessary to review the radiator processing theory aluminum radiator material is appropriate, but to distinguish inserts aluminum, car aluminum, cast aluminum. There is a radiator with a light source and aluminum plates, aluminum shell-contact with each other, the area, and this will directly affect the core temperature of the LED chip conduction and heat dissipation.
Finally, the lighting test
Under normal circumstances, the lighting designer needs to review the lighting test sample. Color temperature, brightness, spot shape, beam angle, lighting the lamp body temperature are reviewed details of the designer, is a few steps from the theoretical front, the face of it, the final result is due to the lighting test this link. Here can be very intuitive judgment whether lighting design effects to match.
