What are the main faults of downlight shell
According to lighting function, downlight shell can be divided into general lighting and partial lighting. Generally, lighting lamps are evenly arranged on the top or side wall of the working site to illuminate the whole working surface. Incandescent lamps, tungsten halide lamps, high-intensity gas discharge lamps with high power or more fluorescent lamps are required. Most downlight housings are of this type. General lighting has a high demand for light dispersion. Two types of light dispersion, direct lighting type and semi direct lighting type, are widely used, especially the latter. Part of the semi direct lighting type lights the ceiling with upward light, which can add the ceiling brightness and create a sounder and brighter environment.
Part of the lighting is a kind of lighting which can travel the illumination of a certain operation part. Its effect can be to strengthen and compensate lighting on the basis of general lighting, and it can also be used as temporary lighting in places that do not need lighting in the past (such as equipment repair and protection places). There are no strict rules for their light distribution. Some lamps are generally installed in the vicinity of the work area, with incandescent lamps and tungsten halogen lamps with safe extra low voltage (≤ 50V, effective value of communication) as the light source. There are (portable) running lights, hanging lights, work table lights, machine tool work lights, etc. In some large factory buildings, the floodlights are sometimes used as part of the lighting.
Although there are many deficiencies in LED downlight housing, for example, the standard does increase the protection cost of manufacturers. But in recent years, LED light source packaging technology and heat dissipation technology continue to improve, the stability of light source has reached a better level. Even if there is one, it is also light decay and color drift, which is mainly due to the unreasonable formation of heat dissipation planning. The direct necrosis is very rare, and the light source is more serious.
Energy saving is an important problem we are facing. In the field of lighting, the use of LED lighting products is attracting the world's attention. As a new type of green light source product, LED is bound to be the trend in the future. In the 21st century, LED will enter the new lighting source era represented by LED.
There are three ways of heat conduction: convection, conduction and radiation. In a closed environment, convection and conduction may be relatively small, and the key to the consideration of fluorescent tubes is to emit heat through radiation.
Safety. Here we mainly talk about PC flame-retardant plastic pipe. Because infrared radiation can penetrate PC pipe, when we plan to consider the use of LED lamp, we can consider more about its safety. With full plastic physical insulation method, even when using non isolated power supply, we can guarantee the safety of use.

Common chips of downlight shell
We are not unfamiliar with downlight shell, which is one of the commonly used LED lamps in daily life. However, we often neglect the small chip when we choose and buy it, which leads to losses. Although the chip is small, it plays an important role in the downlight housing, because it touches the light efficiency and life of the downlight housing, so you must pay attention to it when you buy it.

Precautions for the purchase of downlight shell accessories
Good quality is not what is blown out. If you want to choose high-quality lighting accessories, you need to pay attention to several key points:1. Look at the packaging and trademark. The state forces the manufacturer of downlight shell to mark the following contents on the outer package: rated voltage, voltage scale, rated power and rated frequency. Generally speaking, the trademark printing qual

What is the heat dissipation method of downlight shell
As for downlight shell manufacturers, because the use of LED street lights is very long, so, when purchasing LED street lights, many people will pay attention to the heat dissipation problem of downlight shell. Generally speaking, this problem is solved, and the quality of LED street lights will not be very poor.1. The three prevention plan is selected outside the lamp to deal with the heavy dust
