Compared with LED point light source and ordinary lamp light source, existing surface light source such as flat light source has soft light, no harm to eyes, energy saving, natural light; LED lighting is an emerging industry developed in recent years. Compared with traditional tungsten filament bulbs, which use large current to heat the filament until it emits light, LED only needs a very small current to stimulate a very bright light.

[0003] Existing LED surface light sources will generate a lot of heat when in use. The LED surface light sources are easily damaged due to excessive temperature over a long period of time, which affects the normal use of the LED surface light sources and increases the failure rate. Therefore, it is necessary to improve the structure of the LED surface light source so that the LED surface light source is not easily damaged by excessive temperature and the service life of the LED surface light source is increased. Utility Model Content

[0014] 1. The heat dissipation effect is good, the installation is convenient, and the function of avoiding excessive heat affecting the service life is avoided. Two groups of lamp beads are arranged to emit two rays of light. The light enters the light guide plate to realize continuous emission.

The two rays of light can improve the density and uniformity of light reflection, thereby improving the lighting effect and avoiding the situation of uneven brightness. The heat generated when the light bar 13 is working is transferred to the heat conducting column 7 through the heat conducting bar 15, and then transferred to the heat dissipation bar 16 by the heat conducting column 7. Since the heat dissipation bar 16 is made of aluminum alloy, it has a large heat dissipation area and is stable to use, thereby ensuring the stability of the light bar 13 when in use, and thus can improve the heat dissipation effect.
