LED lighting accessories

With the development of LED lighting, a variety of lighting fixtures have appeared on the market. Currently, LED lighting sources sold on the market are mainly divided into two categories according to their forms: one is COB integrated point light source with multiple chips directly assembled and packaged, and the other is a one-sided light source with a single LED light source through PCB patch. What's the difference between them?

Both types of light source have advantages and disadvantages. For the COB integrated point light source, the luminous surface is small, the light is more concentrated, the package is on the standard LED bracket, the heat dissipation requirements are high; In particular, the three - proof LED lamps and explosion-proof LED lamps with high requirements for structural sealing need special treatment to ensure the service life.

The advantage of one-side light source is that the light source is uniform, the irradiation area is wide, according to the LED chip cooling requirements, more convenient to expand the size of the aluminum substrate, to ensure the life of the LED light source; But the same power of light source, patch light source to dozens of times larger than the COB integrated light source dimension, so the appearance of lamps and lanterns is about to increase, especially are explosion-proof LED lamps and lanterns industry, the lamps and lanterns is relatively heavy, this to a lot of lamps and lanterns manufacturer manufacturing cost is put forward to the test, it is also the LED lamps and lanterns industry, especially in industrial and mining lamp use the COB light.

COB light source technology is also continuously provided, the enterprise continues to improve the processing process, product quality can still meet the use requirements. With the further improvement of product quality awareness, many manufacturers have launched LED SMD products, and many users have started to choose LED SMD products. The BZD series explosion-proof LED lamps we are now launching are compatible with these two kinds of light sources, so that our customers can choose and install them more conveniently.

Knowing these, when buying LED lighting fixtures, we should choose point light source or surface light source according to our own needs and see our actual use. Each has its own characteristics, and the one that suits itself is the best.
