LED glass fly's-eye lens and use its LED lamp

Technical field

This utility model relates to the optical system of LED lamp, particularly relates to optically focused and the projection of collimation and stage LED The optical system of tool.

Background technology

LED has the advantages such as light efficiency is high, light quality is good, energy consumption is little, life-span length, volume are little, just puts with replacement tradition The gesture of electricity bubble light is to high-end lighting field (such as stage lighting, car exhibition lamp, convention hall spotlight, arenas dyeing lamp, studio Projecting Lamp etc.) radiation.Deep masses like for feature that its life-span length is easily maintained.The high-power projection of prior art and stage LED lamp is adopted, in order to more preferably realize that multiple LED lamp bead mixed lights realize super-high-power LED illumination, the super large of especially 20-2000W Power, needs to use fly eye lens array, by the light optically focused of multiple LED lamp bead the target illumination that is collimated to a relatively small area Region, but prior art uses the plastics fly's-eye lens of injection mo(u)lding, has forming surface and meets required optics shiny surface And technique is simple, the feature of low cost, but the projection of the super high power of corresponding 20-2000W and the plastics compound eye of stage lamp Lens, heatproof is low is difficult to stand LED lamp bead heat affecting, easy aging jaundice, water suction, and rigidity is not fine, is easily deformed.

Glass fly's-eye lens just can solve above-mentioned technical problem very well, has heatproof height, good rigidly, is unlikely to deform, is difficult to Aging feature, but fly's-eye lens uses melted press-fitting mould moulding process, during molding, in each lens of fly's-eye lens, especially It is near the central shaft peak of each lens, and easily the bubble coalescence because of molding causes the optics that relative area be can not ignore Face is uneven, does not meets required optically focused collimating optics function, and how to eliminate molding bubble affects this technical problem one Directly solved the most very well.

Utility model content

Based on this, for prior art, technical problem to be solved of the present utility model is just to provide a kind of technique knot Structure is simple, low cost, heat stability are high high-power optically focused and the LED compound eye glass lens of alignment function.

The technical solution of the utility model is as follows:

A kind of LED glass fly's-eye lens, including glass one-body molded make glass plate part, glass fly's-eye lens battle array The optically focused collimation curved portion of row and microfluidic platform part, described glass fly eye lens array is positioned at the same of described glass plate part One side outwardly convex, described glass fly eye lens array at least includes 2 glass fly's-eye lenses, and described microfluidic platform part is for setting Described optically focused collimation curved portion central symmetry axis on diameter dimension 0.1～0.5mm round platform.

Wherein in an embodiment, the frustum cone height of described microfluidic platform part is less than 0.5mm.

Wherein in an embodiment, each described round platform central shaft and each LED lamp bead central shaft of LED light source array Overlap.

Wherein in an embodiment, during installation, described glass fly eye lens array is located at described LED light source array On exiting surface.

Another purpose of the present utility model is the LED lamp submitted to and use foregoing LED glass fly's-eye lens.

A kind of LED lamp, including LED glass fly's-eye lens described above, LED light source array, described LED glass compound eye is saturating Lens array is corresponding with described LED light source array, and what described LED glass fly's-eye lens cover was combined in described LED light source array goes out light On face.

Wherein in an embodiment, each described microfluidic platform portion central axes and each lamp of described LED light source array The central shaft of pearl overlaps.

Hinge structure, LED glass fly's-eye lens of the present utility model has the beneficial effect that, permissible by center band size The microfluidic platform part ignored, simple in construction, low cost of manufacture, optically focused and the collimation merit of required optical lens can be fully met Can, heat resistance is good, is difficult to aging, and good rigidly is unlikely to deform.

Further, the LED lamp of use LED glass fly's-eye lens of the present utility model, super high power lamp can be met Tool requires optically focused and alignment function, is amenable to again the photothermal injury of high-power plurality of LEDs lamp bead, simple in construction, low cost, simultaneously There is the heat resistance that the plastics fly's-eye lens of prior art do not has good, be difficult to aging, good rigidly, it is unlikely to deform etc. prominent Feature.

Detailed description of the invention

Below with reference to the accompanying drawings and in conjunction with the embodiments to this utility model it is described in detail.It should be noted that do not rushing In the case of Tu, the feature in following embodiment and embodiment can be mutually combined.

Fig. 1 gives the structural representation that LED glass fly's-eye lens uses, and Fig. 4 is LED compound eye glass lens structural representation Figure, understands in conjunction with Fig. 1 and Fig. 4, this LED glass fly's-eye lens 20, the glass plate part 23 made including one-body molded, optically focused Collimation curved portion 21 and microfluidic platform part 22.The same side that glass fly eye lens array is positioned at glass plate part 23 is outside Projection, glass fly eye lens array at least includes 2 glass compound eyes saturating 20.Microfluidic platform part 22 is located at optically focused collimation curved portion In the central symmetry axis of 21, for diameter dimension 0.1～0.5mm round platform, frustum cone height is less than 0.5mm.With LED light source battle array When row 10 assembling uses, glass fly's-eye lens 20 array is located at the exiting surface side of LED light source array 10, protruding optically focused collimation Curved portion 21 and microfluidic platform part 22 are arranged outwardly.The round platform central shaft of each microfluidic platform part 22 and LED light source array 10 Each LED lamp bead central shaft overlap.

As shown in Figure 1, the emergent light of LED light source array 10, after the optically focused and collimation of LED glass fly's-eye lens 20, The target illumination face that energy uniform is much smaller to area facing light sources face.

From the above, it may be appreciated that LED glass fly's-eye lens of the present utility model has the beneficial effect that, can be neglected by center band size Microfluidic platform part slightly, simple in construction, low cost of manufacture, optically focused and the alignment function of required optical lens can be fully met, Heat resistance is good, is difficult to aging, and good rigidly is unlikely to deform.

The LED lamp of the use LED glass fly's-eye lens of utility model, can meet super high power light fixture requirement optically focused and Alignment function, is amenable to again the photothermal injury of high-power plurality of LEDs lamp bead, simple in construction, low cost, has prior art simultaneously The heat resistance that do not has of plastics fly's-eye lens good, be difficult to aging, good rigidly, the outstanding feature such as be unlikely to deform.
