Outdoor lighting It is commonly used in urban lighting, decoration, landscape and other functions. It is generally composed of aluminum alloy casing, high-power LED, light distribution lens and waterproof cavity, waterproof drive power supply and so on. Because LED has the characteristics of energy saving, high luminous efficiency, rich color and long life, outdoor lamps of other light sources are gradually replaced by outdoor lamps. Outdoor lighting manufacturers' lamps have gradually replaced other types of landscape lighting, and the future applications will become more and more extensive. Outdoor lighting can be used indoors and outdoors, squares, entertainment places, living rooms, etc. In general, as long as you think of it. Everything can be used, except underwater!
At present, a large number of 0.06W power is used in the industry. If we want to reach 1W, we need 17 identical LEDs with a total brightness of 17*6=102lm, which means 100lm/W. If we use a single chip for 1W of power, the output brightness is 80lm high, commonly used is about 60lm, which is a major difference in brightness.
From the perspective of product cost, the high-power LED cost is higher than the low-power cost. This comes from two aspects, one is the cost of the LED itself, and the other is the high-power LED to add the aluminum heat sink. The low power can be achieved by using a common circuit board and natural heat dissipation.
The power module of the outdoor luminaire is installed inside the casing, and the space is limited. Some manufacturers can solder the surface of the pin-type component to the PCB in order to save space. This is unacceptable. These surface-welded pin-type components are likely to fall off due to soldering or the like, posing a hazard. Therefore, it is necessary to adopt a jack welding method for these components. If the surface welding method has to be used, it is necessary to provide additional protection for the component by means of glue fixing.
Fault testing is a critical test item in product certification testing. This test item is to short-circuit or open some components on the line to simulate the failures that may occur during actual use to evaluate the safety of the product under a single fault condition. In order to meet this safety requirement, it is necessary to consider adding a suitable fuse at the input end of the product to prevent overcurrent from being output short-circuit or internal component failure, resulting in a fire hazard.
