Compared with the prior art, the LED streetlamp is provided with a plurality of heat conducting reinforced ribs and the auxiliary heating plates on the street lamp roof cover of the LED light source for reinforcing the radiation of the LED light source, thereby effectively guaranteeing the normal work of the LED light source.

Description

The LED street lamp

Technical field:

The utility model relates to lighting field, and what be specifically related to is a kind of LED street lamp.

Background technology:

It is light source that traditional road lamp mainly adopts Metal halogen lamp, fluorescent lamp, and these light source volumes are big, and heat dispersion is poor.Along with the succeeding in developing of development of semiconductor and GaN great power LED, LED has obtained at aspects such as signal demonstration, back lightings using widely as semiconductor light sources in recent years.Be accompanied by the development with the high-power LED encapsulation technology of improving constantly of large power white light LED light efficiency, semiconductor light sources begins progressively to be applied to the white-light illuminating field.

Therefore led light source is applied to the concrete application that street lighting is the outdoor lighting of LED white light, but because led light source generates heat more seriously in the course of the work, heat radiation is the subject matter that the restriction led light source is used on street lamp.

Summary of the invention:

For addressing the above problem, the utility model purpose is to provide a kind of LED street lamp with heat sinking function, to avoid causing the street lamp damage because of the led light source heating.

For achieving the above object, the utility model is mainly by the following technical solutions:

A kind of LED street lamp, comprise street lamp top cover, street lamp cover and be arranged at LED road-light light-source between the two, described street lamp top cover is provided with auxiliary heat dissipation plate and many heat conduction reinforcements, and described heat conduction reinforcement one end is positioned at street lamp top cover upper end, and an end is positioned at street lamp top cover lower end.

Connect by street lamp upper and lower covers clasp between described street lamp top cover and the street lamp cover.

Described LED road-light light-source arranged outside has the led light source reflector.

Also be provided with a street lamp upper and lower covers support bar between described street lamp top cover and the street lamp cover.

Described street lamp cover bottom is provided with the street lamp post fixing hole.

Compared with prior art, the street lamp top cover that the utility model is installed led light source is provided with many heat conduction reinforcements and an auxiliary heat dissipation plate, strengthening the heat radiation of led light source, thereby has effectively guaranteed the operate as normal of led light source.

Identifier declaration among the figure: street lamp top cover 1, LED road-light light-source 2, heat conduction reinforcement 3, auxiliary heat dissipation plate 4, road lamp power supply 5, street lamp cover 6, led light source reflector 7, street lamp upper and lower covers support bar 8, street lamp post baffle plate 9, street lamp safety glass 10, street lamp glass cushion rubber 11, street lamp upper and lower covers cushion rubber 12, street lamp upper and lower covers clasp 13, street lamp post fixing hole 14.

The specific embodiment:

For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.

See also Fig. 1～shown in Figure 4, the utility model provides a kind of LED street lamp, particularly a kind of LED street lamp with good heat radiating function, it mainly includes street lamp top cover 1, LED road-light light-source 2 and street lamp cover 6, wherein street lamp top cover 1 and street lamp cover 6 one ends flexibly connect by rotating shaft, the other end then links together by street lamp upper and lower covers clasp 13, and between the two also by street lamp upper and lower covers cushion rubber 12 (see figure 2) that is tightly connected.

Between street lamp top cover 1 and street lamp cover 6, be provided with LED road-light light-source 2 and road lamp power supply 5, wherein LED road-light light-source 2 is installed in the bottom of street lamp top cover 1, and be distributed with many heat conduction reinforcement 3 (see figure 3)s on the street lamp top cover 1, the top of street lamp top cover 1 also is provided with an auxiliary heat dissipation plate 4 and many heat conduction reinforcements 3 in addition, this auxiliary heat dissipation plate 4 is positioned at the correspondence position of LED road-light light-source 2, and the heat conduction reinforcement 3 of street lamp top cover 1 upper and lower overlaps (see figure 4) fully, so that the heat of inside is transmitted to outer surface contact convection current heat is dispersed.

The heat conduction reinforcement 3 here extends around led light source is middle mind-set, can fully the led light source heat be directed at uniformly whole street lamp top cover 1, and street lamp top cover 1 adopts is that high heat conduction aluminium alloy compression casting is one-body molded, has the advantages that heat conduction is fast, thermal resistance is low, heat can be derived rapidly.

Corresponding position, LED road-light light-source 2 installation site is provided with street lamp safety glass 10 on street lamp cover 6 and the street lamp top cover 1, to play the purpose of light source water proof and dust proof, and street lamp glass cushion rubber 11 is installed at street lamp safety glass 10 places, to reach waterproof shock-absorption and heat insulation effect (see figure 3).Road lamp power supply 5, street lamp upper and lower covers support bar 8 and street lamp post baffle plate 9 also are installed on street lamp cover 6 in addition, and wherein road lamp power supply 5 is mainly used in to LED road-light light-source 2 stable working power is provided; When being used for the street lamp later maintenance, supports street lamp upper and lower covers support bar 8 the light fixture top cover; 9 outlets that are used for the street lamp power supply, road lamp power supply cable of street lamp post baffle plate also have effect dustproof and the retaining mosquito simultaneously.

During the utility model assembling, earlier street lamp top cover 1 and street lamp cover 6 are snapped together by street lamp upper and lower covers clasp 13, the street lamp post fixing hole 14 that will be positioned at street lamp cover 6 bottoms then is through on the lamp stand, and (see figure 1) is fixed.
