As shown in Fig. 1～4, the preferred embodiment providing for the utility model.
As depicted in figs. 1 and 2, the utility model embodiment proposes a kind of LED module, and it can be used in street lamp, certainly, also can be used in other light fixture, as in indoor lamp etc., is not limited to the utilization in the present embodiment.
LED module comprises optical lens 11, the ring body 12 with through hole 121, the base 14 that LED light source 13 and metal material are made, the flange 112 that optical lens 11 comprises towards the transmittance section 111 of projection and arranges around transmittance section 111 lower end peripheries, ring body 12 inner sides are provided with the step 122 of depression upward, transmittance section 111 is through through hole 121, flange 112 is connected on step 122, between flange 112 and step 122, be provided with sealing ring 2, ring body 12 is located on base 14, between ring body 12 and base 14, be provided with lower seal 3, optical lens 11, between the upper surface of ring body 12 and base 14, form the cavity volume of sealing, LED light source 13 is located on base 14, be placed in described cavity volume.
In above-mentioned LED module, LED light source 13 is directly placed on base 14 upper surfaces, and base 14 is that metal material is made, thus good heat dissipation effect.
The transmittance section 111 of optical lens 11 is through the through hole 121 of ring body 12, and its flange 112 is connected on the step 122 of ring body 12, and is provided with sealing ring 2 between flange 112 and step 122; Ring body 12 is placed on base 14, thereby optical lens 11 is also placed on base 14, and between the upper surface of optical lens 11, ring body 12 and base 14, forms the cavity volume of sealing, between ring body 12 and base 14, is provided with lower seal 3; After whole LED module has assembled, LED light source is placed in the cavity volume of sealing, thereby has waterproof effect.
As shown in Figure 2, the madial wall of upper sealing ring 2 is provided with the groove 21 caving in, and groove 21 is around upper sealing ring 2 layouts, and flange 112 is embedded in groove 21, and the upper end of upper sealing ring 2 clamps between flange 112 and step 122.After groove 21 parcel flanges 112 in upper sealing ring 2, optical lens 11 is again through the through hole 121 of ring body 12, and step 121 blocks flange 112, easy for installation, and can avoid sealing ring 2 to be offset in installation process, make the sealing property between flange 112 and step 122 stable.
Can certainly adopt other method first upper sealing ring 2 to be fixed on behind the upper surface of flange 112, then with step 122 butts, for example, upper sealing ring 2 is pasted on the upper surface of flange 112.
As shown in Figure 3, the lower surface of ring body 12 arranges the groove 123 that caves in the form of a ring, and lower seal 3 upper ends are embedded in caves in groove 123, and its lower end extruding is contacted with on base 14.Lower seal 3 upper ends pack in the groove 123 that caves in, protrude downwards its lower end, that is to say that the groove 123 that caves in can not pack in groove by lower seal 3 completely, some exposes lower seal 3, this part is padded on base 14 upper surfaces because being squeezed, thereby lower seal 3 makes between the lower surface of ring body 12 and base 14 upper surfaces in sealing state.
The groove 123 that caves in is mainly fixing lower seal 3, avoids lower seal 3 sideslip and cause seal failure when extruding.
As shown in Figure 2, be provided with mounting groove 141 on base 14, mounting groove 141 is arranged in described cavity volume, and LED light source 13 is fixed in mounting groove 141.Mounting groove 141 is convenient to LED light source 13 installations, the space that also increases described cavity volume.
As shown in Figure 4, be provided with wire through-hole 142 in base 14, wire through-hole 142 has two opening 1421, two openings 1421 and is placed in respectively in described cavity volume and outside described cavity volume.Wire through-hole 142 is communicated in outside described cavity volume in described cavity volume, and LED light source 13 need to be connected with extraneous by power line, and obtains the required power supply of illumination, and wire through-hole 142 is convenient to drawing of power line.
Between power line and wire through-hole 142, can be provided with seal, as sealing ring, stop water to enter in described cavity volume from wire through-hole 142.
As shown in Figure 4, two openings 1421 of wire through-hole 142 lay respectively on the lateral wall of base 14 and the sidewall of mounting groove 141, and the power line of LED light source 13 causes outside base 14 via wire through-hole 142.Wire through-hole 142 is laterally located between the lateral wall of base 14 and the cell wall of mounting groove 141, out of doors, rainwater is generally to fall from top to bottom, wire through-hole 142 lateral arrangement, can avoid the rainwater of top to enter in described cavity volume by wire through-hole 142, affect LED light source 13 normal operations.
As shown in Figure 2 and Figure 4, the upper surface of base 14 convexes with bulge loop 143, encloses the cavity that forms opening between bulge loop 143 and the upper surface of base 14, and lower seal 3 and ring body 12 are placed in described cavity, and the upper surface of ring body 12 is placed in described cavity.Bulge loop 143 surrounds lower seal 3 and ring body 12, and the lower seal 3 in described cavity can be avoided being offset original position because being subject to extraneous collision.
The internal diameter of bulge loop 143 equals or is a bit larger tham the external diameter of ring body 12.
As shown in Figure 2, the outer surface of transmittance section 111 is arc surfaced, and it surrounds the cavity that forms lower ending opening.It is that the light of being convenient to LED light source 13 penetrates that transmittance section 111 is arc surfaced one, the 2nd, increase the attractive in appearance of profile; Transmittance section 111 surrounds the cavity that forms lower ending opening, increases the space of described cavity volume.
The utility model also proposes a kind of LED street lamp, comprises LED street lamp body (not marking in the drawings), is provided with at least one above-mentioned LED module on described LED street lamp body.Because LED module has advantages of that good heat dissipation, waterproof are good, the LED street lamp with this LED module also has good heat dissipation, waterproof good.
One or more described LED street lamp module forms a described LED street lamp, only need change out of order LED street lamp module described in that when LED street lamp module breaks down described in one of them, convenient in maintenance afterwards.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
