Problems solved by technology

The above lamp structure makes the light of the LED light source within the half-power angle range of the upper half not irradiate the road surface or other effective areas that need to be irradiated, which not only causes a great waste of light, but also irradiates the light in the sky. This part of invalid light also causes serious light pollution.

Embodiment Construction

[0025] Such as Figure 1 ~ Figure 4 As shown, the LED garden light 1 provided by the present invention includes a fixed bracket composed of two circular chassis 1, 2, and the two chassis 1, 2 are connected by a thin rod 3 at the center of the circle. A plurality of LED light strips 4 that can be independently installed and disassembled form a circle and are installed between the two discs 1 and 2 to form a light source assembly of the LED garden light. Both ends of the LED light bar 4 are respectively fixed on the end faces of the two chassis 1 and 2 by fasteners 5 . A power supply 6 is installed on the other end of the chassis 1, and a lamp cover 9 and a lamp holder 7 are covered outside to be connected to an external power supply. A bottom cover 20 is mounted on the other end of the chassis 2 .

[0026] Such as figure 2 As shown, the LED light bar 4 includes a strip-shaped installation base 40, a plurality of LED light sources 42 are installed at intervals on its outer e...

Abstract

The invention discloses an LED garden lamp comprising a light source component and a mounting bracket, wherein the light source component comprises a plurality of independent lamp strips which are enclosed into a circle, two ends of the independent lamp strips are fixed on the mounting bracket, and a plurality of LED light sources are arranged on the lamp strips at intervals; the mounting bracket comprises two circular base plates, the plurality of lamp strips are arranged between the two base plates at intervals, and the radius r of a circle enclosed by one ends of the lamp strips is smaller than the radius R of a circle enclosed by the other ends of the lamp strips so that the entire lamp has a pagoda shape. The LED garden lamp provided by the invention has a pagoda lamp structure so that rays of an LED light source within the range of a power angle can radiate a road surface or other effective regions as much as possible, thus, the utilization ratio of the light source is increased, the light pollution is greatly reduced, and a good heat radiating effect is achieved.

Description

technical field [0001] The invention relates to the field of LED lighting, and more specifically relates to a structure of an LED garden light. Background technique [0002] Garden lights are a kind of lighting fixtures, which are used in urban roads, residential areas, parks or tourist attractions, and can be used as landscape viewing or living lighting. [0003] After the advantages of LED as a light source are recognized by people, its application fields and places are becoming more and more extensive. Therefore, more and more garden lights using LEDs as light sources appear in daily life. However, due to the luminous characteristics of the LED itself, its luminous angle has a certain range, and there is a certain relationship between the luminous angle and the luminous intensity, and the light emitted along the optical axis of the LED has the highest luminous intensity. Therefore, the reasonable design of the lamp structure can make the application of LEDs in garden la...
