Abstract
The utility model discloses a LED single light source street lamp, which comprises an enclosed chamber formed by a lower case and an upper case, wherein a LED light source is provided on the inner surface of the upper case, an opening is provided on the lower surface of the lower case correspondingly to the LED light source, which is covered by a glass cover, the upper and the lower cases adopt flat structures, the upper surface of the upper case is provided with radiating fins integrally, the radiating fins are composed of a plurality of protruded arc thermal conductive ribs parallel whose middle is higher than two ends. The LED single light source street lamp has simple case structure and simple assembly, wherein the integral structure of the radiating fins and the upper case is beneficial for preventing rainwater and obtaining good heat radiation effect, to control the junction temperature of the LED under 60 degrees.
Description
Technical field
The utility model belongs to field of illuminating lamps, particularly a kind of LED street lamp.
Background technology
LED (semiconductor light-emitting-diode) is a kind of new type light source, compares it with conventional light source and has advantages such as longevity, energy-conservation, low-voltage, volume is little, pollution-free.LED has entered lighting field, when being applied on the street lamp, along with street lamp internal structure difference, the mounting means of LED is varied, the basic structure of LED street lamp is in the housing of a sealing led light source to be installed at present, has an openning on housing, covers the back illumination light transmission with cloche.Most LED street lamp is in order to improve water resistance, and all the upper shell with shell is designed to middle high low arc all around, help the following row of rainwater like this, but the defective of this structure is: 1, the upper shell manufacturing process complexity of shell; 2, very inconvenient when the inner installation of upper shell led light source.Simultaneously, in order to improve the heat dispersion of LED street lamp, most LED street lamps are additional heat device on housing all, when reality is used, can accumulate dust and rainwater between this heat abstractor and the housing.
Summary of the invention
The purpose of this utility model is for overcoming the deficiencies in the prior art, and a kind of simple in structure, good heat dissipation effect, LED single light source street lamp that optical efficiency is high are provided.
The technical solution adopted in the utility model is: form the sealing room by upper shell and lower house, led light source is installed on the inner surface of upper shell, the lower house lower surface place that led light source in correspondence is provided with an opening, this opening covers with cloche, upper shell and lower house are the platypelloid type structure, the upper shell upper surface has fin and upper shell to be integrated, this fin by several to upper process, middle high two ends are low and the arcuation heat conduction muscle that is arranged in parallel is formed.
The utility model housing contour structures is simple, is easy to assembling.The integral structure of fin and upper shell helps the loss and the good heat dissipation effect of rainwater, makes the junction temperature of LED be controlled at 60 ° below the degree.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structure connection diagram of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the right view of Fig. 1;
Among the figure: 1. upper shell, 2. lower house, 3. fin, 4,5. hasp, 6. cloche, 7. wiring board, 8.LED light source, 9. lamp stand pressing plate, 10. plate screw hole, 11. plate screws, 12. sealing rings.
The specific embodiment
Shown in Fig. 1～3, upper shell 1 and lower house 2 are the platypelloid type structure, and upper shell 1 and lower house 2 are formed the room that seals.Sealing ring 12 is installed between upper shell 1 and lower house 2, hasp 4 and hasp 5 respectively is installed, play a part to connect and the fixing lower house of going up in the both sides of upper shell 1 and lower house 2 length directions.The installation place that is positioned at lamp stand on upper shell 1 and lower house 2 has corresponding plate screw hole 10, and plate screw 11 is installed by plate screw hole 10, in order to the lamp stand pressing plate 9 in the middle of fixing.
Led light source 8 and wiring board 7 are fixedly mounted on aluminium base on the inner surface of upper shell 1, and led light source 8 can be the integrated light source that the plurality of LEDs light source is linked to be composition, or single high-power LED light source.The lower house 2 lower surface places that led light source 8 in correspondence are provided with an opening, and this opening covers with illumination light transmission with cloche 6 sealings.Upper shell 1 upper surface is formed integral structure by fin 3 and upper shell 1, this fin 3 by several to upper process, middle high two ends are low and the arcuation heat conduction muscle that is arranged in parallel is formed.The length of fin 3 and width are all respectively less than the length and the width of upper shell 1.
Described upper shell 1 and fin 3 be with high-purity aluminium ingot die casting one-shot forming, and hasp the 4, the 5th is made with stainless steel materials, and the strong advantage of non-corrosive and fastness is arranged.Lower house 2 is with the moulding of raffinal plate stretching, and the advantage of fastness height and light weight is arranged.Cloche 6 is made by high temperature resistant, high-intensity safety glass.Sealing ring 12 is to be made by high temperature resistant, aging-resistant silicon rubber, plays good sealing and dustproof effect.Lamp stand pressing plate 9 is the iron plate punch formings by 5 millimeters, carries out plating zinc on surface again and handles.
