Problems solved by technology

Because the heat cannot be dissipated, its life is seriously affected and it will cause rapid light attenuation
All over the world are trying to overcome this problem, but most of them are difficult to break through the shackles of traditional ideas and lamp structure models, and it is difficult to achieve a good cost performance and a novel and beautiful appearance.

Embodiment 1

[0029] Fig. 1a to Fig. 7 are specific embodiments of a 70W street lamp cap of the present invention. This embodiment includes a street lamp base, including a connecting skirt 1, a light-emitting unit base 2, an installation base 3 installed at the center of the bottom of the light-emitting unit base 2, an LED aluminum substrate 7 fixed on the installation base 3, a power supply box 8, and a press Cover 4, glass cover 5, rubber pad 6, LED light-emitting tube 9, cover plate 10. The power supply box 8 can provide a PWM DC square wave voltage of 36V and 3A, and provide a driving voltage to each light-emitting unit base 2 .

[0030] As shown in Figure 1a and Figure 1b: the base of the light-emitting unit adopts a heat source dispersion design. With each 10W as the basic unit, it is designed as a light-emitting unit with various regular or irregular shapes, self-contained, self-radiating and easy to assemble.

[0031] As shown in Fig. 2: the base body of the light-emitting unit ad...

Embodiment 2

[0043] 8a to 8d are specific embodiments of the 50W street lamp base of the present invention. This embodiment shows various structural shapes in which the body of a 50W LED street lamp is composed of a light-emitting unit base 2, which is not only beautiful, but also good for heat dissipation. Others are the same as in Example 1.

Abstract

The present invention discloses a lighting device, particularly discloses a LED street lamp. The LED street lamp includes street lamp head which consists of luminous unit base, installing base which is installed on the central position of the luminous unit base bottom, LED aluminum base plate fixed on the installing base and power box, its special characteristics are: said luminous unit base is hollow wheel rib structure. Said luminous unit base is opened with dissipating heat groove around itself. Said street lamp head includes many luminous unit base which is regular shapes or normal shapes and its basic unit is 10W or 20 W per each lamp head. The invention effectively resolves in the dissipating heat issue of working LED and realizes the feature of long life of LED lamp.

Description

(1) Technical field: [0001] The invention relates to a lighting device, in particular to an LED street lamp. (2) Background technology [0002] The structure of the traditional street lamp body is to embed an aluminum alloy lampshade in a die-cast aluminum or aluminum-plastic alloy sealing body. Finally, the front is sealed with a glass mask to form a street lamp as a whole. [0003] The current LED street lamps basically follow the appearance of the past street lamps, even if there are some innovations, there are still various problems. Traditional street lamps are designed around existing light bulbs (such as high and low pressure sodium lamps, mercury lamps, etc.), which only guarantee the sealing and other requirements that meet the characteristics of traditional lamps, and are not suitable for LED lamps. [0004] As a new type of lighting source, LED has attracted more and more people's attention because of its energy saving, environmental protection, long service lif...
