Description

Support lamp

Technical Field

The application relates to the technical field of lighting, especially, relate to a creepage distance accords with support lamp of ann's rule.

Background

The LED light source and the driving power supply generate a large amount of heat during use, and particularly for high-power lighting products, a metal shell is usually required for heat dissipation, but the metal shell has an electric shock risk, and therefore an isolated driving power supply is usually adopted. Although the isolation driving power supply has the best isolation effect, the number of driving components is large, the size is large, and the cost is high.

The non-isolated driving power supply directly outputs direct current after receiving commercial power, does not contain isolated electronic components, and has electric shock danger when touching a load. In order to solve the above technical problems, the aluminum substrate is usually replaced by an insulating substrate in the prior art. For example, patent publication No. CN207674133U discloses replacing aluminum substrate with ceramic substrate, but the mechanical properties of ceramic substrate are not as good as aluminum substrate; some of the techniques are to add an insulating member between the aluminum substrate and the metal case, and as disclosed in patent document CN208457775U, the lamp panel and the lamp body are isolated by an insulating tape. But the increase of the isolation layer can affect the heat dissipation of the lamp panel.
