Description

A panel light with cooling function

technical field

The utility model relates to the technical field of semiconductor lighting, in particular to a panel light with heat dissipation function.

Background technique

LED panel lights use LEDs as light sources, and cooperate with light guide plates and diffusion plates to form uniform surface light source lamps. They have the characteristics of good uniformity of illumination, soft light, and long service life. , is gradually replacing the existing grille lights, and is widely used in office building lighting and other public places. LED panel lights are used as indoor lighting fixtures. During the working process of the lamp beads, only a small part of the electric energy is converted into light energy, and most of the electric energy is converted into heat energy. That is to say, the LED lamp beads will generate a lot of heat while emitting light. When they are installed together, it will often cause heat concentration, causing the LED lamp beads to be in a high temperature state, which seriously affects the luminous efficiency and service life. Especially in the occasions where large LED panel lights need to be used, since the number of LED lamp beads inside the large LED panel lamp is large, and the heat energy released by the LED lamp beads is also large, if only relying on the heat sink to dissipate heat by itself, the efficiency will be very high. Low, the cooling effect is not good, which has a great negative impact on the life of large LED panel lights. However, large LED panel lights are often expensive. If the heat dissipation problem of large LED panel lights cannot be solved, it will directly affect the economy of LED panel lights At the same time, it limits the promotion of LED panel lights, and plays a certain role in hindering the occupation of large lighting market share.
