Abstract

The utility model discloses a concentration light LED lamp with strip lens, comprising a matched base, a power supply and a light source board which controls a connecting interface. The light source board is formed by a light source substrate and at least one LED core sheet which is matched with the light source substrate and connected electrically. Inner wall end parts of two sides of the base are inlayed with strip lens. The base, the light source substrate are corresponded with the shape of the strip lens, the strip lens mould is low in manufacturing cost and short in development cycle. Wall thickness of the strip lens is even, with accurate location and low requirement, which makes the product process generalized with high yield. The LED core sheet arrangement distance has no limit, which is high in intensity and increases applying range. The utility model has characters of good bunching reflection ray effect, good concentration light performance and good color rendering, which makes the using effects of the LED lamp displayed fully.

Optically focused LED lamp with rod lens

Technical field

The utility model relates to the technical field of LED lamp, relates in particular to the optically focused LED lamp with rod lens through lens light gathering.

Background technology

Have outstanding advantages such as low-voltage driving, low energy consumption, radiationless, long-life because of LED, various decoration occasions and advertising sector and night guidance lighting etc. be widely used.But the LED beam divergence, and extremely inhomogeneous, many occasions form light pollution; The shortcoming of collection lens: Mold Making cost height, and the construction cycle is long; Poly-lens and the dull and stereotyped wall thickness drop that links to each other cause its manufacture craft strict and the waste product that yields poorly is many, and material cost is high; Lens unit and LED positioning accuracy request height; Poly-lens volume and spacing limitation down, the led chip density of arranging is low.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the defective of present technology, provides a kind of cost of manufacture low, and the location is smart, the density height, and have that the clustering refracted ray is effective, optically focused reaches the good optically focused LED lamp with rod lens of colour rendering well.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the optically focused LED lamp with rod lens, comprise equipped mutually base and the light source board that power supply and control connection port are arranged, light source board is made up of light source substrate and at least one led chip of being formulated on the light source substrate and being electrically connected, and the technical measures of taking comprise: inwall end, base both sides is embedded with rod lens.

The technical measures of taking also comprise: above-mentioned rod lens is a vertical element shape collector lens, and the cross section outer contour of this vertical element shape collector lens is a parabola; Described vertical element shape collector lens optically focused angle is that 0 degree is to 60 degree.

Above-mentioned base, light source substrate are corresponding with the shape of strip collector lens; The light source substrate face parallels with bar shaped collector lens bottom surface, and the arbitrary led chip on the light source substrate is centered close on the described bar shaped collector lens cross section axis.

Above-mentioned strip collector lens is a linear, or is shaped form, or the combination shape of making up mutually for linear, or the combination shape of making up mutually for shaped form, or is the combined combination shape of linear and shaped form.

Above-mentioned base is a concave body, and the inwall middle part, both sides of base concave body is embedded with described light source substrate, and the inwall middle part, both sides of base concave body is equipped concavo-convex guide rail, and the end is oblique convex body; Described light source substrate sidewall is plugged in the concavo-convex guide rail of described base; Described rod lens two bottom sides limit is shaped on the corresponding oblique groove that coincide with the oblique convex body of described base respectively.

Compared with prior art, inwall end, the utility model base both sides is embedded with rod lens.Base, light source substrate are corresponding with the rod lens shape, and rod lens Mold Making cost is low, and the construction cycle is short; The rod lens wall thickness evenly and the location essence require low and make the production technology generalization and the output height; The led chip arrangement pitches is unrestricted, and the density height then increases range of application; It has, and the clustering refracted ray is effective, optically focused reaches the good characteristics of colour rendering well, thereby makes the result of use of LED lamp give full play to.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Fig. 1 to Fig. 4 is the optically focused LED lamp with rod lens of embodiment one to embodiment four, and Fig. 5 is that the A-A of Fig. 1 is to the cross section cross-sectional schematic.

Optically focused LED lamp with rod lens, comprise equipped mutually base 1 and the light source board that power supply and control connection port are arranged, light source board is by light source substrate 2 and be formulated on the light source substrate 2 and at least one led chip 3 that is electrically connected is formed, and inwall end, base 1 both sides is embedded with rod lens 4.

Fig. 1 and Fig. 5, embodiment one are that rod lens 4 is vertical element shape collector lens, and the cross section outer contour of this vertical element shape collector lens is a parabola; Described vertical element shape collector lens optically focused angle is that 0 degree is to 60 degree.Base 1, light source substrate 2 are corresponding with the shape of strip collector lens; 2 of light source substrates parallel with bar shaped collector lens bottom surface, and the arbitrary led chip 3 on the light source substrate 2 is centered close on the described bar shaped collector lens cross section axis.Base 1 is a concave body, and the inwall middle part, both sides of base 1 concave body is embedded with described light source substrate 2, and the inwall middle part, both sides of base 1 concave body is equipped concavo-convex guide rail 1a, and the end is oblique convex body 1b; Described light source substrate 2 sidewalls are plugged among the described base 1 concavo-convex guide rail 1a; Described rod lens 4 two bottom sides limits are shaped on the corresponding oblique groove 4a that coincide with described base 1 oblique convex body 1b respectively.So, light source substrate 2 can conveniently insert among the concavo-convex guide rail 1a of base, and firmly spacing at upper-lower position; Coincide corresponding with base 1 oblique convex body 1b of rod lens 4 oblique groove 4a is equipped with, and structure is very tight.
