Preferably, has the separation space between the adjacent carrying tablet.
Certainly, have the lighting apparatus of the transparent cover of some special shape,, can not separate the space between the then adjacent carrying tablet as the transparent cover of cylindricality, and as a whole.But, if transparent cover is a sphere, or the ellipsoid shape, need have the separation space between the then adjacent carrying tablet, just can better open and be affixed on the transparent cover inwall.
Preferably, the shape of described carrying tablet is identical, is arranged in parallel successively.
Further, the quantity of described carrying tablet is at least 3, and the separation void shape between the adjacent described carrying tablet is identical.
Adopt abovementioned technology, then can guarantee to be arranged on the light-emitting device in the transparent cover, the arrangement of its luminescence unit is more even, and its illumination effect is also more even.
Preferably, the end of described carrying tablet is up-narrow and down-wide shape.
Wherein, above-mentioned up-narrow and down-wide shape comprises trapezoidal, is a tip, but is not to refer to trapezoidal on the strict geometric meaning, as triangle, also can be considered as above-mentioned trapezoidal a kind of special form.
When if transparent cover is a sphere, or the ellipsoid shape time, if do not adopt abovementioned technology, then the end of open different bearer sheet will overlap in transparent cover, can influence the effect that assembling is installed like this.
Preferably, described flexible substrates comprises following structure sheaf: metal level that intercouples and flexible PCB layer, described flexible PCB layer is connected with described luminescence unit.
Further, described metal level and flexible PCB layer are bonding by heat-conducting glue.
Further, described metal level selects to adopt aluminium flake.
Adopt abovementioned technology, not only have elasticity preferably,, also be convenient to install luminescence unit, also have heat dispersion preferably simultaneously so that open.
Certainly, described metal level also can adopt other metal or alloy material, but through the overtesting contrast, adopts the heat dispersion of aluminium flake comparatively good.
Preferably, have the heat dissipation channel that several are arranged in order on the described brace.This heat dissipation channel also can be corresponding with the heat dissipation channel that is arranged on the pedestal, further improves its heat-sinking capability.
