Abstract
The utility model relates to an LED lens which structurally comprises a lens body and a mounting part connected with the lens body, wherein a power source accommodating cavity used for accommodating an LED lamp is arranged at the bottom of the lens body, a cavity is arranged at the top of the lens body, the inner wall of the cavity adopts a fully reflecting surface, the mounting part is provided with threads, and the LED lens is assembled in a screwed manner through the threads. The LED lens provided by the utility model adopts the threads to replace fixing legs, when assembling is performed by an assembling operator, all that is needed is to align the threads with a screw hole to screw, the assembling is simple and time-saving, and the efficiency is high.
Description
Technical field
The utility model relates to a kind of LED lens, is specifically related to a kind of LED lens that are easy to assembling.
Background technology
LED(Light Emitting Diode, Light-Emitting Diode) have that volume is little, low, the long service life of consuming energy, brightness is high and the advantage such as sturdy and durable, LED lighting engineering develops very soon in recent years, the illuminating products such as LED lamp are also promoted rapidly in China, just slowly replace the main light fixture that traditional incandescent lamp becomes normal lighting.
In dropping into actual use, conventionally can be at the additional LED lens of LED chip, to adjust the light path of the light that LED sends, meet actual user demand.Existing LED lens, arrange several fixing feet conventionally, by fixing feet, assemble.Yet, the LED lens that this employing fixing feet is assembled, when it is assembled, assembly crewman needs first fixing feet to be alignd one by one, bothers very much time-consumingly, and efficiency of assembling is low.
Summary of the invention
For addressing the above problem, this practical information provides that a kind of assembling is simple, efficiency is high, simultaneously good, the LED lens that are easy to assembling of versatility.
For achieving the above object, the utility model provides following technical scheme.
LED lens, comprise lens body and the installation portion being connected with lens body, the bottom of described lens body is provided with the light source accommodating cavity for accommodating LED lamp, the top of described lens body is provided with cavity, the inwall of described cavity is set to fully reflecting surface, described installation portion is provided with screw thread, and this LED lens assemble in the mode being spirally connected by described screw thread.
Wherein, described installation portion and lens body are one-body molded.
Wherein, described installation portion one end is connected with lens body, and described screw thread is located at the other end of described installation portion.
Wherein, the lens that this LED lens are axially symmetric structure, the axial length of described installation portion be this LED lens axial length 1/5 ~ 2/5.
The beneficial effects of the utility model are: LED lens of the present utility model adopt screw thread to substitute fixing feet, and when assembly crewman assembles LED lens of the present utility model, the screw that only screw thread need be alignd screws, and assembling simply saves time, efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of LED lens of the present utility model.
Fig. 2 is the structural representation of the vertical section of LED lens of the present utility model.
Fig. 3 is the schematic diagram of light path of the fully reflecting surface reflection ray of LED lens of the present utility model.
Reference numeral comprises: lens body 1, installation portion 2, light source accommodating cavity 3, cavity 4, fully reflecting surface 41.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.
As depicted in figs. 1 and 2, LED lens of the present utility model, comprise lens body 1 and the installation portion 2 being connected with lens body 1, the bottom of lens body 1 is provided with the light source accommodating cavity 3 for accommodating LED lamp, and lens body 1 top is provided with cavity 4, the inwall of cavity 4 is set to fully reflecting surface 41, like this, as shown in Figure 3, the light that incides fully reflecting surface 41 has just been totally reflected, thereby it is dark to obtain centre, around bright hot spot.Installation portion 2 is provided with screw thread, and LED lens of the present utility model assemble in the mode being spirally connected by screw thread.Owing to adopting screw thread to be spirally connected, it is a kind of connected mode very common in daily life, LED lens of the present utility model adopt screw thread to substitute fixing feet, the assembling mode of the LED lens that assemble from existing those employing fixing feet is different, when LED lens of the present utility model are assembled, the screw that only screw thread need be alignd screws, and assembling simply saves time, efficiency is high.
Wherein, the installation portion 2 of LED lens of the present utility model can with lens body 1 one-body molded (as shown in Figure 1), the one-body molded (not shown) of the lens body 1 of also can getting along well.When installation portion 2 is not and lens body 1 is one-body molded, installation portion 2 can be used as a crossover sub separately, the corresponding syndeton of fixing feet with existing LED lens is set in one end of installation portion 2, this one end is connected with the existing LED lens that are provided with fixing feet, then the other end at installation portion 2 by screw thread, like this, when needs are changed LED lens, if want the lens that change not adopt screw thread to assemble, just can use this installation portion 2 to be used as crossover sub.
In addition, the lens that LED lens of the present utility model are axially symmetric structure, the axial length of described installation portion 2 be LED lens of the present utility model axial length 1/5 ~ 2/5.In the present embodiment, the axial length of installation portion 2 be LED lens of the present utility model axial length 1/4, so just can guarantee, under the prerequisite of firmly installing, does not affect again the illuminating effect of lens.Because if the axial length of installation portion 2 is oversize, the position of LED lamp will be too near the bottom of LED lens of the present utility model, thereby affect the illuminating effect of LED lens of the present utility model; If the axial length of installation portion 2 is too short, just can not guarantee that the firm of LED lens of the present utility model installed.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not restriction to the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not depart from essence and the scope of technical solutions of the utility model.
