Specific embodiment

The utility model is described further below with reference to embodiment.

As shown in figures 1 to 6, the LED crossbar with high heat dispersion includes cross pedestal 1, power module and luminous group Part.There are four luminescence components, and power module is mounted on 1 center of cross pedestal, four luminescence components and cross pedestal 1 connection, the output end of power module are connect with four luminescence components respectively, and the output end of power module has anode and cathode.Electricity Power module protective shell is equipped with above source module, power module protective shell includes set casing 2, and shell 3 is cased with outside set casing 2. Lampshade 4 is equipped with above luminescence component.Set casing 2, shell 3 and lampshade 4 are equipped with grab 6, and cross pedestal 1 is equipped with card slot 5, card Hook 6 is inserted into card slot 5, so that set casing 2, shell 3, lampshade 4 be made to connect respectively with cross pedestal 1.

Luminescence component includes aluminum substrate 7 and 32 LED lamp bead 8, and two adjacent LEDs lamp bead 8 is connected with rectangular copper foil 9.Square Shape copper foil 9 is connected on the front of aluminum substrate 7, and the size of rectangular copper foil 9 is 18mm × 14mm, and 32 LED lamp beads 8 are connected on Together.LED lamp bead 8 is close together with the glue of aluminum substrate 7 or attachment well known to other, and 32 LED lamp beads 8 are in two column point Cloth, each column 16.It is 10mm along the spacing C between the two adjacent LEDs lamp bead 8 of 7 length direction of aluminum substrate, along aluminum substrate Spacing B between the two adjacent LEDs lamp bead 8 in 7 wide cut directions is 16mm.Between LED lamp bead 8 and the side edge of aluminum substrate 7 Distance D be 9mm.The anode of concatenated 8 head end of LED lamp bead and power module connects, and the cathode of tail end and power module connects It connects.

1 bottom of cross pedestal is equipped with 48 rectangular vents 10, and cross pedestal 1 is made of four parts, and every part is set There are 12 rectangular vents.The back side of the aluminum substrate of each luminescence component is close together with cross pedestal 1, and each shine group Part corresponds to 12 rectangular vents 10 (back side that rectangular vent is located at aluminum substrate), and 12 rectangular vents 10 are in two column point Cloth, each column 6.

As shown in FIG. 7 and 8, rectangular vent 10 is grating type ventilation and heat mouth, opens that there are three strips arranged side by side Thermovent is respectively；First strip thermovent 10-1, the second strip thermovent 10-2, third strip thermovent 10-3.Pass through this The gridiron structure of sample being made of three strip thermovents, can greatly improve the heat dissipation effect to aluminum substrate.
