Each assembled module body is fixed to a module groove so that one module can be formed. The included angle between every two modules is an obtuse angle and the modules are fixed to a module frame and then connected to the lamp pole connector. According to the LED street lamp with the included angles, the appropriate included angles are formed between the modules, so that the lighting range of the street lamp is increased and light rays are distributed evenly.

Description

The LED street lamp that has angle

Technical field

The utility model relates to a kind of illuminations, further relates to a kind of road illumination instrument, further relates to a kind of LED illuminating street lamp.

Background technology

LED street lamp, it is the high efficiency solid-state light source that the faint electric energy of use that a kind of based semiconductor PN junction forms just can be luminous, under certain forward bias voltage and Injection Current, the electronics that injects the hole in P district and inject N district sends photon diffusing to active area by radiation recombination, electric energy is converted into luminous energy.It is a kind of solid-state cold light source, the feature such as there is environment friendly and pollution-free, little power consumption, light efficiency is high, the life-span is long, and therefore, LED street lamp will become the optimal selection of roadway illumination and energy saving transformation

Prior art is generally that a plurality of light emitting diodes are concentrated and are fixed on an aluminium sheet, causes LED street lamp light emitting region narrow, and light skewness.Because existing LED street lamp illumination range is narrow, cause the bar of LED street lamp apart from maintaining between 20---30 rice; Due to existing LED street lamp uneven illumination, cause the section between bar distance to occur sometimes obvious dark space.

Utility model content

In view of above content, be necessary to provide a kind of LED street lamp, make light-illuminating scope extensively and light distributed uniform.

The utility model provides a kind of LED street lamp that has angle, comprises LED lamp module, LED lamp module frame and lamp stand connector.Wherein, in described LED lamp module, comprise module, light emitting diode, lens, cover plate.Light emitting diode is fixed in module, described lens are placed on light emitting diode, cover plate is covered on lens, form the module assembling, the module assembling is fixed in the module groove of module frame, form the module assembling, the angle between described module is obtuse angle, and then module frame is connected to lamp stand connector.

Compared with prior art, the utility model has the advantage of,

(1) illumination range of LED street lamp is expanded to the twice of prior art nearly, and reach the height mean allocation of light.To reach maintenance cost, the hardware cost that reduces LED street lamp, the object that practicality is high.

(2) by designing suitable angle between module and module, make the irradiation scope of street lamp wide, and distribution of light is even.

The specific embodiment

As shown in Fig. 1-7, Fig. 1 is module, and Fig. 2 is light emitting diode, and Fig. 3 is lens, and Fig. 4 is cover plate, and Fig. 5 is the module assembling, and Fig. 6 is lamp stand connector, and Fig. 7 is module frame.The assembling of LED street lamp is as follows, and LED street lamp comprises LED lamp module, LED lamp module frame and lamp stand connector.Wherein, in described LED lamp module, comprise module, light emitting diode, lens, cover plate.Light emitting diode is fixed in module, and described lens are placed on light emitting diode, and cover plate is covered on lens, form the module assembling, the module assembling is fixed in module slot, forms module, angle between described module is obtuse angle, and then module frame is connected to lamp stand connector.

Embodiment mono-:

Module in this embodiment is by module composition

As being constructed as follows of module A in Fig. 81: light emitting diode (number of light emitting diode is more than 2) is fixed on in module, (number of modules is more than 1, a plurality of light emitting diodes can be fixed in a module, also can be by the corresponding module of each light emitting diode), with lens, be placed on respectively (the corresponding lens of each light emitting diode) on light emitting diode, cover plate is covered on lens, form the module assembling; The module assembling (more than 1) is fixed in the module groove of module frame, has just formed module A 1; By the module assembling in lamp mould bases (module number is more than 2), shape (angle is obtuse angle) at a certain angle, finally connects upper lamp stand connector again.

The design of the present embodiment (as Fig. 8) is between every adjacent module, to form obtuse angle: the angle that module A 1 and module A are 2 is as figure A5, and the angle that module A 2 and module A are 3 is as figure A6, and the angle that module A 3 and module A are 4 is as figure A7.

Generally speaking, the angle between module and module is less, and the range of exposures of light is wider, if but light intensity in range of exposures more, with the uniformity in time, also can be affected.So will design suitable angle according to actual conditions (such as pole height, road surface situation), make light that whole LED street lamp sends can reach wide, and it be very even to distribute.

Embodiment bis-:

As Fig. 9, module B3, B4 consist of modular unit; Module B1, B2 are by module composition.Now take module B3 as its constructive method of example as follows: first the module assembling (number of modules is as more than 2) is joined together to form a modular unit as figure B5, modular unit (number of modular unit is more than one) is fixed in module groove, has just formed module B3; Be fixed on the angle (angle is obtuse angle) that (number of module is more than 2) between the module and module on module frame forms a bit: the angle forming between module B1 and module B3 is as figure B6, and the angle forming between module B1 and module B2 is if the angle forming between figure B7, module B2 and module B4 is as figure B8.

The improvement that the utility model carries out mainly for LED street lamp, these are only the utility model preferred embodiment, non-so limit to the scope of the claims of the present utility model, therefore simple and easy variation and the equivalent transformation of such as doing by the utility model description and graphic content, all should be contained in the scope of the claims of the present utility model.
