Points to keep in mind when choosing LED lights in the home

Currently, in the market, LED lights are a popular product and diversified models. Depending on the type, the quality and price of indoor LED lights are different. Here are some points to consider for customers to consider when choosing LED lights for their families.

Lamp cover

When choosing LED lights in the home, customers need to determine which material the housing is made of. There are about 2 types of lamp covers, 1 is aluminum alloy material, 1 is plastic. There are differences between these two types of materials. If the aluminum alloy case, the ratio of aluminum as much as possible. The reason is that aluminum absorbs heat and helps to prolong LED life. If the lamp housing has a low aluminum ratio, it will lighten the weight of the luminaire, but this contributes to reducing the life of the lamp.

LED chip

Indoor LED lights often use single LED chips as light sources that are 1W or 3W LED chips. This is the most popular and popular lamp model today.

LEDs use SMD chips as light sources. SMD chips are mounted on the printed circuit board and inside the seal after the organic glass or light diffusion panel.

The quality of LED chips determines the brightness and degradation of light bulbs. Good LED chips are chips that not only have high luminous flux but also low brightness degradation. The price of the bulbs equipped with different chips also varies greatly. The same type of 1W light bulb but when equipped with different chips, the price may vary from 2 to 10 times.

Heat dissipation technique in LED

Like traditional lamps, when operating, the light source in the LED also produces heat. Fast or slow heat dissipation will determine the process of light degradation and lamp life. The light source works long at high temperature, the brightness will decrease rapidly, the life expectancy will be shortened. This will lead to poor brightness, not achieving the desired lighting effect.

The main material of lamp shell and conventional heat sinks are copper, aluminum and plastic. In particular, copper radiator is better than aluminum, aluminum radiates better than plastic. Currently, in the market, the majority of heat sinks are made of aluminum. It is best to have aluminum with slotted, poorest aluminum radiator cast. In particular, the heat sink of aluminum slotted pieces brings the highest efficiency. In addition, customers need to check the thickness, height, sophistication, surface treatment of the shell and heat sink. These factors directly affect whether the heat dissipation of the bulbs is good.

Power source driver

LED is a semiconductor device with very sensitive properties, and has negative thermal properties. Therefore, during the application process, it is necessary to operate in a stable and protected state. The requirements of LED components for power supply controllers are very demanding, unlike conventional incandescent lamps, LEDs only use low voltage 2-3V. So the driver's circuits are designed to be quite complicated, different LED LEDs use different drivers.

Optical engineering

In order for LED chips to produce light efficiently, meet the requirements, as well as satisfy the lighting requirements in architecture, optical enhancement design for LED chips is also called, twice lighting, lighting 2 times mainly directed light emitted from LED chip focused to the desired area. Since then, meeting the lighting design requirements of the entire lighting system. Lenses and reflectors are two accessories that are mainly used to enhance light twice. This is the solution to improve brightness, pleasant feeling, minimize blinding phenomenon. At the same time perform better optical coordination, improve lighting efficiency effectively.
