This utility model is further arranged to: described radiating copper sheet is circular arc, and two described radiating copper sheet are in relatively setting Put and formed a cavity, be connected in described appliance plate is placed in cavity and with radiating copper sheet insulation.

By using technique scheme, appliance plate is coated with by radiating copper sheet, thus appliance plate surface is played One protective effect, and the heat installing enclosure interior can be shed in time, reach more preferable cooling-down effect.

This utility model is further arranged to: described mounting shell is evenly arranged with away from pin one end and along its circumferencial direction Some caulking grooves, it is one_to_one corresponding and embedding that described lampshade is evenly arranged with caulking groove along its circumferencial direction near mounting shell one end The fixture block that establishing is closed.

By using technique scheme, it is possible to making lampshade and mounting shell more stably connect, fixture block can be embedded Make in caulking groove lampshade cannot rotate installing on housing, thus ensure that the globality of LED, multiple caulking grooves and The cooperation of fixture block increases both bonding strengths, makes lampshade be difficult to from mounting shell depart from.

This utility model is further arranged to: described radiating copper sheet has bonding away from being connected between pin one end and light source board Thing, described fixture block and caulking groove are bonding by adhesive.

By using technique scheme, utilize adhesive to make lampshade and mounting shell connect with serving higher intensity, make Lampshade cannot depart from mounting shell, it is ensured that the safety of internal components, also ensures that the safety of personnel, it is to avoid produces with internal components Directly contact；Meanwhile, adhesive also plays the connection of radiating copper sheet and light source board, such that it is able to entered by the heat on light source board The timely heat loss through conduction of row.

This utility model is further arranged to: described lampshade includes that light collecting layer and photic zone, described light collecting layer are provided with The optically focused post of photic zone direction depression.

By using technique scheme, it is possible to use the light source that light tiles is produced by the optically focused post in light collecting layer is carried out Optically focused, enables the light of light tiles to be gathered in same point as far as possible, thus just can strengthen the luminous intensity of this LED, it is thus achieved that more Good illuminating effect.

In sum, this utility model has the advantages that and combines radiating copper sheet, louvre, radiating groove and bonding Thing, it is possible to the heat within mounting shell and lampshade is carried out quick heat loss through conduction, thus reduces the temperature of inside, make element reach Preferably using effect, increases the service life.
