Abstract
The utility model discloses an improved lens device of a light-emitting diode (LED) street lamp. The improved lens device comprises a housing; an LED lamp, a convex lens and a semiterete arc lens are arranged in the housing from bottom to top in turn; and the housing comprises two parts which are connected into a whole through screw threads or a buckle. The improved lens device has the following advantages: firstly, the original fixing housing is divided into the two parts which can be connected into a whole through the screw threads or the buckle, therefore the exact demand in location dimension is reduced during the assembly, and the street lamp body is convenient to be mounted; and secondly, two elliptical concaves are formed on the two sides of the one third part of the axial length/axial direction of the semiterete arc lens, therefore the semiterete arc lens is further improved, the light emitted by the LED lamp is refracted and reflected, more light beams are diverged towards one side, the light after passing through the lens is more uniformly distributed, the ratio between the length and the width of the light spot is increased, the uniformity degree of the light on the irradiation surface is improved, and the demand in using the street lamp is satisfied.
Description
Technical field
The utility model relates to a kind of diverging light source lens device, particularly a kind of modified LED street lamp lens device.
Background technology
I disclose a kind of LED street lamp lens device in the early time in Chinese patent literature CN201259147Y, can satisfy the needs that the above LED high power light source of 1W is applied to street lamp, can make its light path higher, and am more even with the distribution in time.This device comprises LED lamp, convex lens, housing and is fixed on the support of enclosure interior, its special feature is the curved lenses of arranged outside at convex lens, be semi-cylindrical, can make emergent light growth ellipse or rhombus vertically the dispersing of the circular light spot of incident.Adopt curved lenses when increasing irradiated area, to realize transition stably, controlled light decay effectively, improved effective luminance of led light source, increased the light path of led light source, make light shine fartherly.It is also advantageous in that the controllability that has increased led light source, make the hot spot of lamp be oblong or rhombus, enlarged effective irradiated area of light, rely on the refraction reflection of light fixture will reach the purpose of dispersing than conventional road lamp, the better effects if of dispersing of the present utility model, and the good uniformity of hot spot does not have obvious shade light and speckle.
In use, because of the combination form of aforementioned means for all lens all are installed in the fixing housing, when in assembling, adopting fixing many lens of screw, can produce the deviation of centre-to-centre spacing, produce dislocation with perforate on the street lamp face shield, cause assembling difficulty relatively.
The utility model content
The technical problems to be solved in the utility model provides a kind of modified LED street lamp lens device, has better assembling and better light treatment effect.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of modified LED street lamp lens device comprises housing, and LED lamp, convex lens and semi-cylindrical curved lenses are installed in the described housing from bottom to top successively, and described housing partly constitutes by two, adopts the mode of screw thread or buckle to link together.
Described semi-cylindrical curved lenses grinds 2 oblong pits at axial length 1/3rd places along two side pressures of lens cylinder axis direction.
Described convex lens are lenticular lens; The geometric center of described LED lamp, convex lens and semi-cylindrical curved lenses is located along the same line, and the three is parallel to each other.
The utility model has reduced the strict demand of assembling to location dimension by original stationary housing being divided into two branch body structures that can be connected by screw thread or buckle, has made things convenient for the assembling of street lamp body; Simultaneously the semi-cylindrical curved lenses has been done further improvement, by at its axial length 1/3rd places, grind 2 oblong pits along two side pressures of lens cylinder axis direction, LED lamp emission light is reflected and reflex, more light beam is dispersed to a side, made scioptics distribution of light afterwards more even, increase the length-width-ratio of hot spot, improve the uniformity of shadow surface glazing, can satisfy the instructions for use of street lamp.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the composition structural representation of modified LED street lamp lens device described in the utility model;
Fig. 2 is a modified LED street lamp lens device structure cutaway view described in the utility model;
Fig. 3 is the vertical view of Fig. 2.
Among the figure:
1, LED lamp; 2, lower housing portion; 3, lenticular lens; 4, semi-cylindrical curved lenses; 5, housing top; 6, rib; 7, screw thread; 8, oblong pit; 9, street lamp housing front panel; 10, street lamp housing backboard.
The specific embodiment
As shown in Figures 1 to 3, provided a specific embodiment of modified LED street lamp lens device described in the utility model, LED lamp 1, convex lens 3 and semi-cylindrical curved lenses 4 are installed in the housing from bottom to top successively, this housing is made up of lower housing portion 2 and housing top 5 two parts, and two parts connect as one by screw thread 7.
Wherein convex lens 3 are lenticular lens, the spot light of LED lamp 1 emission can be carried out dispersing of the first step; Semi-cylindrical curved lenses 4 is at axial length 1/3rd places, grind 2 oblong pits 8 along two side pressures of lens cylinder axis direction, light through convex lens 3 is carried out the refraction and the reflection in second step, more light beam is dispersed to a side, make scioptics distribution of light afterwards more even, increased the length-width-ratio of hot spot, improve the uniformity of shadow surface glazing, light is distributed as much as possible to the central authorities and the length direction on road, make street lamp obtain better radiation response.
During assembling, as shown in Figure 3, lower housing portion 2 adopts screw to be fixed on the street lamp housing backboard 10, through hole and lower housing portion 2 that housing top 5 is passed on the street lamp housing front panel 9 spin together, housing top 5 is provided with rib 6, its diameter is greater than through-hole diameter during making, can play the good effect of blocking, if set up corresponding cushion rubber in the outside of street lamp housing front panel 9 simultaneously, also can play good water-tight effect, adopt the outside mode that screws in to reduce the strict demand of assembling simultaneously, made things convenient for the assembling of street lamp body location dimension.
