How to choose the use and selection of cob lens?

The cob lens is an LED light source with packaging technology, referred to as the COB light source, COB lens is a lens configured according to the COB light source, and the light source is processed twice!

Xiangshun Optics is here to share with you about the use of cob lenses and what aspects to consider when choosing?

The use of cob lens:

Because it used to be a traditional lamp, the COB light source uses a reflector. For example, metal halide lamps are made from reflectors. Therefore, colleagues in the industry made some small changes on the basis of the original lamp, applied it to the COB light source, and at the same time adopted the reflector, which may be closer to the lighting of the traditional light source, so it is more in line with the user's usage customs. Therefore, at that time, most enterprise's Reflectors are used.

Today, a small COB light source can reach 50W or less. At the same time, we can make a separate COB lens, which may be a very small angle. If a reflector is used, due to the construction size range of the reflector, using a small angle will cause the volume of all lamps to deviate from New Year's Eve. At present, the method of using lenses for COB light sources is being vigorously promoted, because lenses not only have disadvantages in improving the overall layout of lamps, but also the luminous effect may achieve the goal of killing two birds with one stone.

Nowadays, with the application of COB light source in the accessories market, the reflector is gradually reduced, and the lens occupies the mainstream. After the COB lens is continuously consumed, the pairing of the COB light source will be dominated by the lens, and the reflector will gradually withdraw from the market! The COB light source lens is for sure. In addition, lens products will have more disadvantages in import certification and safety specification testing, and reflectors cannot get there.

What aspects should be considered when choosing a COB lens?

1. Spot selection of COB lens

The spots are divided into circular spots, oval spots and rectangular spots. Circular spot with lower lighting requirements and lighting range for indoor lighting lenses. The elliptical spot can use unevenly distributed light and light that exceeds the road, has a strong light-gathering ability, and is generally used in hotel and restaurant series lighting lenses. The rectangular spot has a strong light-gathering ability, and the light is evenly irradiated on the road after the light is concentrated so that the light can be applied to a large extent.

2. Viewpoint standard of COB lens

The optical requirements required by different roads also vary. For example, in restaurants, hotels, main clothing stores, offices, courtyard communities, etc., the height of the lights should take into account different viewpoint standards. Choose a suitable viewpoint to meet the light needs of past crowds.

3. Information on COB lens

Common lens data include glass lenses and plastic lenses. Because plastic has good high-temperature resistance; while glass has the characteristics of high-temperature resistance and high penetration, and can choose optical parameters by itself, its large quality and fragility also limit its application range. New Data PC lens and PMMA lens are optical plastic data, which can be formed by plastic, extruded products, with high productivity and low data cost, showing significant advantages once applied in the market. If you want to choose an affordable lens, you can choose a PC lens and a PMMA lens.
