The specific embodiment
For describing technology contents of the present utility model, architectural feature, the purpose that is realized and effect in detail, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 1, the 100 main Fresnel Lenses leaded light modes that adopt of the LED lamp with Fresnel Lenses that present embodiment disclosed conduct the LED unit go out after the Fresnel Lenses refraction as the light that light source sends.This LED lamp 100 with Fresnel Lenses comprises light guide 10, illuminating part 20 and load bearing seat 30.This illuminating part 20 is contained in the load bearing seat 30, and light guide 10 is arranged at illuminating part 20 tops and is inserted on the load bearing seat 30.And the part of this illuminating part 20 is stretched out outside the lamp body of this LED lamp 100.In the present embodiment, this LED lamp 100 is elongated.
As Fig. 2, the light guide 10 of this LED lamp 100 is one to be the Fresnel Lenses of strip.The outside horizontal-extending in this bottom, light guide 10 two sides forms the plug-in mounting rib.Illuminating part 20 comprises LED unit 22 on circuit board 21, welding and the circuit board 21, be connected with circuit board 21 and be welded in the socket 23 of circuit board 21 left ends and be installed in two electric connecting sheets 24 in the socket 23.Circuit board 21 is strip, circuit board 21 right-hand member upper surfaces form the metal forming 25 of two spaced and parallel through the circuit board typography, the electric connecting sheet 24 of accommodating in the socket 23 of circuit board 21 left ends protrudes out socket 23 downwards, when two LED lamps 100 are plugged on together, metal forming 25 can electrically conduct with the electric connecting sheet 24 of pegging graft.This load bearing seat 30 is strip, and its cross section is roughly U-shaped, and load bearing seat 30 bottoms are provided with bottom outlet 33 and locating hole 34 near left end, and load bearing seat 30 both sides cave inward and form first holddown groove 31 and second holddown groove 32 of bar shaped.One alignment pin (not shown) partly is arranged in the locating hole 34, and another part of alignment pin is arranged in the hole of offering on the circuit board 21, makes that the illuminating part 20 that is installed in the load bearing seat 30 can be owing to this load bearing seat 30 is stretched out in the push-and-pull of external force.Load bearing seat 30 is made by metal material, particularly make by aluminum alloy material, being close to load bearing seat 30 bottoms when circuit board 21 is provided with, the heat of LED unit 22 conducts after this load bearing seat 30 radiate via circuit board 21, with the operating temperature of reduction light fixture integral body, and then the service life of prolongation light fixture.
As shown in Figure 3, the demonstration that this sectional view is detailed the position and the relation of installing of LED lamp 100.The plug-in mounting rib that the both sides of this light guide 10 extend to form is plugged in first holddown groove 31 of load bearing seat 30, and circuit board 21 is plugged in second holddown groove 32.The upper surface of light guide 10 becomes the zigzag of symmetry, i.e. Fresnel pattern, and the lower surface of light guide 10 offers short slot, and LED unit 22 stretches in this short slot.Electric connecting sheet 24 stretches out this bottom outlet 33 downwards.
When two LED lamps 100 are plugged on together, circuit board 21 right-hand members as a LED lamp 100 of plug stretch between the socket 23 and load bearing seat 30 of the 2nd LED lamp 100, the electric connecting sheet 24 of the 2nd LED lamp 100 is tight against the metal forming 25 on the plug of a LED lamp 100, makes two LED lamp 100 electric connections.
When single led lamp 100 uses, can be between bottom outlet 33 and electric connecting sheet 24 the plug-in mounting insulation board, to prevent being connected the short circuit that causes with other electric conductors owing to this electric connecting sheet 24 stretches out.
The socket of LED lamp 100 also can stretch out outside this lamp body, and plug is contained within the lamp body.Socket also can be arranged at the below of circuit board and be electrically connected with circuit board, also can be arranged at the below of circuit board as the metal forming of plug, and the plug and socket that all is arranged at the circuit board below can be pegged graft mutually.And when described LED unit replacement was the LED unit of three look RBG, the quantity of metal forming was four, and the corresponding electric connecting sheet that is arranged in the socket also is four.In order to prevent the covering of dust to Fresnel Lenses, above Fresnel Lenses, install protective cover additional, this protective cover is the transparent light guide body, and this protective cover upper surface is a shiny surface, and the dust that can conveniently face toward to fall is thereon cleared up.
That more than disclose only is in the preferred embodiment of the present utility model one.In the specific implementation, this LED lamp can be made rectangle dress or toroidal or elliptical shape, corresponding, the light guide that is arranged on the LED unit can be arranged to single Fresnel Lenses.The mounting means of light guide and load bearing seat is not limited to the plug-in mounting mode, also can be that spiral-lock or the mode of clamping realize.Originally the integral thickness that has the LED lamp of Fresnel Lenses reduces, and bright dipping is effective.Shown among Fig. 4 for realizing same light fixture irradiating angle, the lens 10 of traditional plano-convex pattern ' with the thickness difference of Fresnel Lenses, the thickness of the planoconvex spotlight of traditional mode is much larger than the thickness of Fresnel Lenses.
In sum, protection domain of the present utility model is not limited to the foregoing description, still all should belong to interest field of the present utility model as for the change of component count described in this specification or the replacement of equivalent elements etc.
