Three misunderstandings of wireless charging led table lamp heat dissipation

time: 2021-10-13 view:802

At present, there are a variety of LED table lamps on the market, such as led table lamps with Bluetooth speakers, led table lamp with wireless charging, eye protect table lamps and so on. These table lamps are also deeply loved by consumers. Of course, consumers are also very concerned about the heat dissipation of their own LED table lamps. After all, the heat dissipation of a product is directly related to its quality and service life. Here, manufacturers of wireless charging led table lamps are dedicated to answering questions for consumers.

1. The superstition of thermally conductive materials.
Because any high-tech material can dissipate heat. It uses ordinary aluminum to dissipate heat. After many tests, the temperature of the radiator is only 3-5 degrees Celsius higher than the bottom of the radiator. In other words, if materials with excellent thermal conductivity can be used, when the thermal resistance is zero, the temperature can be reduced by 3-5 degrees Celsius.

2. The superstition of heat pipes.
There is no doubt that the heat pipe has good thermal conductivity. However, the heat of the radiator eventually needs to be taken away by air convection. If there is no heat sink to dissipate heat, the heat pipe will quickly reach thermal equilibrium, and the temperature will rise with the heat sink. If the heat pipe is equipped with a heat sink, the heat sink will eventually dissipate heat. Moreover, the contact point between the fin and the heat pipe is not as good as in other aspects. As a result, the cost is high, and the heat dissipation effect is not improved. However, it is still useful to use heat pipes to conduct heat on the integrated LED, but the structure should be reasonable!

3. Superstition in nano-radiation materials.
At present, at a lamp temperature of about 50 degrees Celsius, the proportion of radiation is negligible. Even if the radiant paint advertised by the manufacturer has a good heat dissipation effect, even if it reaches the heat dissipation capacity of black body radiation, its heat dissipation rate is only a few percent. The significance of this matter has yet to be considered! Moreover, the coating itself will hinder heat transfer, thereby affecting convective heat dissipation.

    The impact of reading table lamp on daily life

    reading table lamps are a non-negligible existence for a family, because ordinary lighting is not suitable for long-term reading, study and work needs. Especially young people, if the lamp is not selected well during the learning process, it is easy to suffer from myopia. Reading/writing is done with eyes at close range, and the requirements for light are very high. The appropriate brightness is in a small range (about 300Lx) and must be sufficiently stable. In residential areas, if there is a need for reading/writing, in addition to ceiling lamps, there should be table lamps to fill the books/desktops. Lamps must also distinguish between daily lamps and learning lamps. In the process of reading, comfort is the real eye protection....
