Lighting fixtures refer to a device that capable of light transmitting, distributing, and changing the light distribution, including all the components necessary for securing and protecting the light source, in addition to the light source, the wiring accessories are necessary for connection to the power source. Lighting fixtures used in all aspects of our lives, and we can do nothing without it in our daily life, the progress of mankind and social production also can not be separated from it. Various types of Lighting fixtures on the market, but outdoor LED lighting is a relatively wide application of lighting fixtures. So, what matters should pay attention to on installation of outdoor lighting fixtures?

Work environment of outdoor LED lighting fixtures:

As the working environment is more complex, effected by the temperature, ultraviolet, humidity, rainy days, dust, chemical gases and other natural conditions, environmental factors should be considered in the design of LED outdoor lighting fixtures.

Packaging technology of outdoor LED chips:

At present, domestic production of LED lighting fixtures (mainly street lights) are mostly used 1W LED strings, parallel assembly, this method is called packaging technology. 30W, 50W or even larger modules to be assembled to achieve the required power, these LED packaging materials use epoxy resin package. The difference between the two is: epoxy resin package has a poor temperature resistance, easy to aging for a long time. Silicone packaging with a better temperature resistance, should pay attention to choice when use.

Matters should pay attention to in the choice of cooling materials for outdoor LED lighting fixtures:

Select aluminum or aluminum alloy with good thermal conductivity, copper or copper alloy, as well as other alloys.

Reserch in design of the radiator for outdoor LED lighting fixtures:

Clear the power that the LED lights need for thermal dissipation.

The type of thermal dissipation. Cost comparison: natural convection cooling with the lowest cost, strong wind cooling are medium, heat pipe cooling cost is higher, jet cooling with the highest cost.

Design of the radiator parameters: thermal conductivity of metal, chips, radiator, Air thermal resistance of ambient air and so on.

Calculate the volume, area, and shape of the radiator.

At room temperature of 39 ℃ - 40 ℃, whether the temperature of the lighting fixtures meet the cooling requirements, if not met, then recalculate and adjust.

Determine the maximum permissible operating temperature of the outdoor LED lighting fixtures.

Waterproof, dustproof, anti-aging, stainless steel bolt fastening, and then in accordance with the promulgation of China's latest outdoor lighting technical specifications, as well as urban road lighting design standards.
