[specific embodiment]

See also shown in Figure 1, the utility model mainly is made up of substrate 20, a reflector 30, an enclosing cover 40 and several elasticity clips 50 that a heat sink 10, is provided with several light emitting diodes 21, in present embodiment, further comprise a waterproof gasket 60, this waterproof gasket 60 is between heat sink 10 and enclosing cover 40.

In present embodiment, so the general rectangular shape of this illumination module is also roughly rectangular shapes such as aforesaid heat sink 10, substrate 20, reflector 30, enclosing cover 40 and waterproof gaskets 60; Wherein:

This heat sink 10 has a upper plate 11 and a lower plate 12, and it is parallel relative that this upper and

lower plate

11,12 is, and the two also is provided with several vertical rib 13 to interconnect, and makes 11,12 of upper and lower plates keep a spacing, and constitutes a sandwich structure; Upper and lower again

plate

11,12 is formed with several fin ribs 110,120 in opposite inner face, to increase area of dissipation.Moreover upper and

lower plate

11,12 is formed with a fixing hole 111 respectively in contiguous each corner, supplies the fixedly usefulness of aforesaid base plate 20.

This substrate 20 mainly is to be made of a circuit board, is formed with the connection line (not shown) on it, and the upper surface of substrate 20 is provided with several light emitting diodes 21 again, and each light emitting diode 21 is that the connection line that sees through on the substrate 20 interconnects, to constitute the loop; Moreover, in the present embodiment, be to make the light emitting diode 21 on the substrate 20 do the matrix arrangement; Substrate 20 each corner are formed with fixing hole 22 respectively in addition, each fixing hole 22 is corresponding to the fixing hole on the heat sink 10 111, substrate 20 is fixed on the heat sink 10, its the two and constitute thermo-contact, when each light emitting diode 21 is worked on the substrate 20, the heat energy of its generation must conduct to heat sink 10, utilizes heat sink 10 to provide bigger area of dissipation to dispel the heat with acceleration.

This reflector 30 is to cover on substrate 20, be formed with enclosure wall 31 around the reflector 30 again, its surface then forms the reflector 32 of several indents, the outer bottom of reflector 32 is the bottom surfaces that protrude in reflector 30 again, moreover each reflector 32 bottom is to be permeable type, and correspond respectively to each light emitting diode 21 on the substrate 20, when light emitting diode 21 is luminous, the light of its generation will penetrate after reflector 32 surface reflections earlier again, to improve brightness.

This enclosing cover 40 is a light-permeable, it is the hollow lid that a bottom is sky, the degree of depth of its inner accommodation space that forms is the matched that adds reflector 32 with the height enclosure wall 31 of reflector 30, and can supply reflector 30 ccontaining therebetween (please cooperate consult shown in Figure 2).Enclosing cover 40 stretches out to form a rectangular-shaped eaves portion 41 in the bottom peripheral region again, the length and width degree of this enclosing cover 40 in these eaves portion 41 places is the length and width degree that is matched with heat sink 10, and be suitable for covering on the upper plate 11 of heat sink 10, in present embodiment, be provided with this waterproof gasket 60 between the eaves portion 41 of this enclosing cover 40 and the heat sink 10, this waterproof gasket 60 is rectangle frame sheets, mainly be to constitute by elastomeric material, can guarantee to present compact state after enclosing cover 40 and heat sink 10 utilize elasticity clip 50 that it is mutually combined, so under the composite construction, not only dustproof and have a waterproof action.

Enclosing cover 40 is formed with several recessed slot parts 42 in its eaves portion 41 surfaces again, and this slot part 42 is the uses that cooperate elasticity clip 50, making things convenient for elasticity clip 50 clips in this eaves portion 41, and is difficult for left and right sides transposition.
