Abstract
The utility model discloses an LED lens which is conical; the conical bottom of the lens is in alignment with an LED chip; the LED lens is characterized in that at least two fixing pieces extend downwards from the conical top surface of the LED lens from a direction in parallel with the conical central axis, and the bottom of the fixing pieces are adapted to a fixing hole which is arranged on an aluminum substrate for fixing the LED chip. The LED lens has simple installation procedures, does not shake, can realize precise focus with the LED chip and has high light integration efficiency. In addition, because an installation hole is arranged on the aluminum substrate, the heat radiation of an electronic element is facilitated.
Description
Technical field
The utility model belongs to the optical articles field, relates in particular to a kind of LED lens.
Background technology
Semiconductor lighting (LED) product is the environmental protection and energy saving product that present country widelys popularize, and market and application prospect are boundless.In the LED illuminating product, the LED lens are absolutely necessary.The LED lens have important effect for light extraction efficiency, the optical field distribution of LED.The LED lens mainly use optical grade PMMA material to make at present, and shape is generally taper, the accurate contraposition of its conical lower portion and led chip.The encapsulation assembling of LED lens and led chip generally is to adopt following pattern: led chip is fixed on the aluminium base, and led support is buckled on the led chip, the LED lens is placed in the adaptive with it led support, to realize the focusing of LED lens and led chip.In production practices, find that following point appears in such assembling mode in actual applications easily: (1) is because the LED lens are to be placed in the adaptive with it led support, as long as the LED lens walk a little, it is inaccurate to cause focusing in the moving process, reduces polishing and closes efficient; (2) assembly process complexity must be buckled in led support on the led chip earlier, and then place the LED lens, and error appears in any procedure, all can directly have influence on the accurate contraposition of LED lens and led chip; (3) production cost height.In order to simplify linkage editor better, improve the precision of focusing, be necessary existing LED lens are improved.
The utility model content
It is a kind of convenient for assembly that the purpose of this utility model is to provide, and helps accurate focusing, saves the LED lens of cost.
Be the technical scheme that realizes that the purpose of this utility model adopts: a kind of LED lens, tapered, its conical lower portion and led chip contraposition, it is characterized in that, along extending at least two stators with being directed downwards of conical centre line parallel, the fixing hole of offering on the aluminium base of the bottom of described stator and fixed L ED chip is suitable from described LED lens taper end face.
Adopt technical scheme as above, just can need not to produce and led chip and the suitable led support of LED lens, provide cost savings, only the bottom of LED lens stator need be fixed on the fixing hole of offering on the aluminium base that is provided with led chip during assembling and can realize effective location, assembly process is simple, assemble rear lens and can not rock, help precisely focusing with led chip.
Further technical scheme is, described stator is two, and described two stators are with respect to the center line center symmetry of taper.Such structure stator minimum number, cost is minimum, and realization that still can the LED lens is effectively located.
Described stator is down " protruding " shape, and the fixing hole of offering on the boss of described " protruding " shape and the aluminium base of fixed L ED chip is suitable.
The described platform of " protruding " shape is trapezoidal, the limit of the described trapezoidal LED of the being positioned at lens taper end face＞trapezoidal limit that is positioned on the LED lens base plane.Such structure can further be saved the cost of material compared with rectangular structure.
The utility model with respect to the advantage and the effect of prior art is:
1, LED lens of the present utility model by stator directly is set, need not to use support in the process of assembling on lens, simplified the program of assembling, have saved production cost.
2, LED lens of the present utility model effectively are fixed on the aluminium base by stator, can not walk when mobile, can focus very accurately with led chip, have improved the integration efficiency of light.
3, LED lens of the present utility model when installation fixing piece, need be offered corresponding hole on aluminium base, so also help the heat radiation of electronic devices and components, help prolonging the service life of electronic device.
Description of drawings
Fig. 1 is the structural representation of existing LED lens;
The LED lens arrangement schematic diagram of Fig. 2 a embodiment one, Fig. 2 b is the left view of Fig. 2 a, Fig. 2 c is the vertical view of Fig. 2 a.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
The structure of existing LED lens as shown in Figure 1, it is tapered, comprises taper end face 1 and taper bottom surface 2, focus by support and led chip in taper bottom surface 2.Fig. 2 a～Fig. 2 c is LED lens of the present utility model, compare with existing lens, from existing LED lens taper end face 1 along extending the center line center symmetry of 3, two stators 3 of two stators with respect to taper with being directed downwards of conical centre line parallel.Stator 3 is down " protruding " shape, and the fixing hole of offering on the aluminium base of boss 3.1 of " protruding " shape and fixed L ED chip is suitable.The platform of " protruding " shape is trapezoidal, the limit 3.2 of the trapezoidal LED of the being positioned at lens taper end face＞trapezoidal limit 3.3 that is positioned on the LED lens base plane.This trapezoidal structure adopts rectangular structure more to save material than the platform of stator 3.
LED lens of the present utility model are that like this assembling is used: be opened in two suitable holes of stator 3 bottom boss 3.1 on the aluminium base of fixed L ED chip, the stator of LED lens inserted just can realize in the described hole effectively having located.
Show after the use that use LED lens of the present utility model, lens can not rock, can realize focusing accurately the integration efficiency height of light with led chip.And, help the heat radiation of electronic devices and components owing to offered installing hole on the aluminium base.
The foregoing description is the utility model preferred implementation; but embodiment of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under spiritual essence of the present utility model and the principle, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
