Embodiment Construction
[0043] figure 1 is a schematic perspective view of the LED light source substrate 100 according to the first embodiment of the present invention. The LED light source substrate 100 may include a substrate body 110 . The substrate body 110 may be shaped in a sheet shape. figure 1 A schematic structural view of the substrate body 110 of an embodiment is shown. like figure 1 As shown, the substrate body 110 may generally include a metal base layer 13 , an insulating and thermally conductive layer 14 and a copper foil layer 15 . Wherein, the metal base layer 13 may be aluminum base or copper base. In other embodiments, the metal base layer 13 may also be other metal bases with good thermal conductivity. It can be understood that when the metal base layer 13 is aluminum-based or copper-based, the substrate body 110 is correspondingly an aluminum-based copper-clad laminate or a copper-based copper-clad laminate.

The invention provides an LED light source substrate. The LED light source substrate comprises a substrate body formed into a sheet-like shape, a plurality of through grooves and a plurality of LED light source sites, wherein the through grooves are formed in the direction of a connecting line from the outer periphery of the substrate body to the center of the substrate body at intervals and used for partitioning the substrate body into a plurality of substrate units which are connected mutually, and each substrate unit is provided with a first surface; the LED light source sites are arranged on the first surfaces of the corresponding substrate units and used for containing LED light sources; the length of the through grooves is smaller than the distance between the outer periphery of the substrate body and the center of the substrate body; and all the substrate units are configured to be capable of being arbitrarily bent, so that the illumination plane formed by concurrent illuminating of all the LED light sources is not lower than a maximum preset illumination plane. According to the scheme, the problems about illumination dead angle and heat dissipation are solved through the through grooves and the segmentation technology, and meanwhile the stability of a circuit is improved.
Description
technical field [0001] The invention relates to the technical field of lighting devices, in particular to an LED light source substrate. Background technique [0002] The new national standard for elevators requires the lighting of shafts, pits, and car tops to reach 20LUX in most areas of the shaft. Since the elevator shaft is a vertical structure, the illuminance in the shaft should reach all directions as far as possible, especially the illumination in the vertical direction, so as to achieve the lowest number of lights to cover the entire shaft. [0003] However, the existing LED lights generally adopt LED flat panel light sources. Since the maximum emission angle of the LED patch is generally 150°, the side light, especially the side light greater than 150°, cannot reach the front of the vertical plane. Therefore, the LED flat panel light source has problems such as lighting blind spots. In order to solve the problem of lighting dead angles, a method of increasing th...
