How to choose a better led ceiling lamp
There are many kinds of LED lamps in the market, and it is impossible to start. We choose LED ceiling lamps from two aspects, so that you can choose satisfactory and cost-effective lamps and lanterns
On the one hand, how to choose the quality of led ceiling lights
1. Selection of mask shell for led ceiling light. What kind of mask should the led use? Be sure to use a mask made of pc material. The acrylic mask is fragile, and the PC cover will bounce back automatically even if you press the mask hard with your fingers. The light transmittance of acrylic is as high as about 90%, you will feel that the light is very bright, and the light of the PC cover is softer and more uniform and not easy to turn yellow. The case is larger and better for heat dissipation.
2. The heart of the led ceiling lamp - the choice of constant current drive power. As the name implies, constant current can still maintain a balanced current when the voltage fluctuates to make the led ceiling light work normally, and will not cause damage to the led ceiling light due to voltage fluctuations. There is no text wave. Use the camera function of the mobile phone to take a picture of the light that is on. If the effect in the mobile phone is uniform, it means that the quality of the light is good. On the contrary, if there are ripples, it means that the quality of the lamp is not good. Often its life depends on the life of the power supply. The vulnerable parts of the power supply are electrolytic capacitors. When the electrolyte dries up, the life of the lamp will end, and it must be replaced with a new one.
3. The choice of led lamp beads. In addition to the constant current driver, the life and light decay of the LED ceiling lamp is also a very critical factor. Regarding the quality of lamp beads, there is no standard in the industry. Only the merchant can guarantee you the service life. For example, let the merchant promise you that it will not light for 2 years or have serious light failure. write on. Therefore, consumers do not need to pay too much attention to the origin of the chip. However, the quality of the chip is still passable now, and the chance of bad is relatively small.
On the other hand, how to choose the size of led ceiling light
It is generally determined according to the size of the irradiation area. The larger the area, the higher the power requirements. For example, the power of the bedroom should be larger. The balcony/aisle does not require very high brightness, so you can choose a lower power. In order to save electricity, many All use induction led ceiling lights.
Generally speaking, low-power led ceiling lamps can illuminate a small area, and high-power led ceiling lamps can illuminate a large area.
Therefore, after understanding the above principles, you will easily choose the ceiling lamp you need.
Choose the power of Led ceiling light according to the size of the room
5-10 square meters can use LED-18W white light
10-15 square meters with led-30W white light
15-20 square meters with LED-40W white light
20-30 square meters with LED-50W white light
30-40 square meters with LED-70W white light
The above parameters are for reference only. If the LED ceiling lamp is of good quality and high luminous efficiency, the power can be appropriately reduced. Since the LED ceiling lamp is round, the illumination is relatively concentrated, and the irradiation area is not as good as that of the LED tube. When the area is relatively large, it is recommended. Compared with LED fluorescent lamps, the first is because the irradiation area is large, the second is because the cost of fluorescent lamps is lower than that of ceiling lamps, and the third is cost-effective. LED fluorescent tubes are excellent in power saving.
