A kind of led crossbar

Technical field

The utility model is related to a kind of lighting device, more particularly to a kind of led crossbar.

Background technology

LED lamp is made up of multiple lighting units mostly, and each lighting unit is again by several led lamp beads serial or parallel connections even Connect and form.Because it has the advantages that energy-conservation, efficient, stable and environmental protection, in the life more and more applied.

But, unreasonable due to designing, LED lamp still suffers from the problem of non-uniform light, poor radiation, short life.

Content of the invention

The utility model is directed to existing led crossbar non-uniform light, poor radiation, the technical problem of short life, provides A kind of luminous uniformly, thermal diffusivity is good, life-span length led crossbar.

For this reason, the utility model includes cross pedestal, power module and luminescence component；Luminescence component has four, lights It is provided with lampshade above assembly；Power module is arranged on cross base central position, and luminescence component is connected with cross pedestal, electricity Source module is connected with luminescence component；It is provided with power module containment vessel, power module containment vessel includes set casing above power module, It is cased with shell outside set casing；Set casing, shell and lampshade are equipped with grab, and cross pedestal is provided with draw-in groove, grab insertion card Groove, set casing, shell and lampshade are connected with cross pedestal respectively；Luminescence component includes aluminium base and led lamp beads, and led lamp beads have 32, two neighboring led lamp beads rectangular copper foil connects；On aluminium base, the size of rectangular copper foil is 18mm to rectangular copper foil × 14mm, 32 led lamp beads are series connection, and are in two column distributions, each column 16；Two neighboring along aluminium base length direction Spacing c between led lamp beads is 10mm, along spacing b between the two neighboring led lamp beads in aluminium base wide cut direction is 16mm；Led lamp beads and the distance between the side edge of aluminium base d are 9mm.

Preferably, led lamp beads and aluminium base are close together；The output end of power module has positive pole and negative pole, series connection Led lamp beads head end is connected with positive pole, and tail end is connected with negative pole.

The beneficial effects of the utility model are that led lamp beads have 32, and two neighboring led lamp beads are connected with rectangular copper foil, square On aluminium base, the size of rectangular copper foil is 18mm × 14mm to shape Copper Foil, and the thermal diffusivity of rectangular copper foil is than traditional fine rule Bar Copper Foil thermal diffusivity is well a lot, and 32 led lamp beads are series connection, and is in two column distributions, each column 16；Along aluminium base length Spacing c between the two neighboring led lamp beads in direction be 10mm, along aluminium base wide cut direction two neighboring led lamp beads it Between spacing b be 16mm；Led lamp beads and the distance between the side edge of aluminium base d are 9mm.Draw through many experiments Spacing is so that led crossbar is luminous more uniform.
