Technical field

The utility model relates to LED lamp technical field, specifically is 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: the Mold Making cost is high, 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 are high; Poly-lens volume and spacing limitation down, the led chip density of arranging is low.

The utility model content

The utility model technical problem to be solved is to provide a kind of cost of manufacture low, and the location is smart, and density is high, and has that the clustering refracted ray is effective, optically focused property reaches the good optically focused LED lamp with rod lens of colour rendering well.

The utility model for the technical scheme that the technical solution problem adopts is,

A kind of 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 that is formulated on the light source substrate and be electrically connected; It is characterized in that: inwall end, said base both sides is embedded with rod lens, and 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.

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

Described strip collector lens is a linear, or is shaped form, or the combination shape of making up each other for linear, or the combination shape of making up each other for shaped form, or is the combined combination shape of linear and shaped form.

Described 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 output is high; 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 property reaches the good characteristics of colour rendering well, thereby makes the result of use of LED lamp give full play to.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.

A kind of 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 by light source substrate 2 be formulated on the light source substrate 2 and at least one led chip 3 that is electrically connected is formed, inwall end, base 1 both sides is embedded with rod lens 4.

Among Fig. 1 to Fig. 5, embodiment one is 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, and 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 and bar shaped collector lens bottom surface parallel, and the arbitrary led chip 3 on the light source substrate 2 is centered close on the 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; Light source substrate 2 sidewalls are plugged among the base 1 concavo-convex guide rail 1a; Rod lens 4 two bottom sides limits are shaped on the corresponding oblique groove 4a that coincide with base 1 oblique convex body 1b respectively.So, light source substrate 2 can conveniently insert among the concavo-convex guide rail h 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.
