Abstract

An LED garden lamp with excellent radiation effect belongs to the technical field of lighting, which is used to solve the problem of radiation of an LED garden lamp. The utility model adopts the technical scheme that the LED garden lamp comprises a lampshade, a lamp holder and a radiating lamp-socket, wherein the lamp holder is connected with the radiating lamp-socket through a heating conducting copper pipe. The LED garden lamp not only has wide illumination range, but also has excellent radiation performance, greatly improves the lighting effect of LEDs, and prolongs the service life of an LED chip.

Description

A kind of LED garden lamp with great heat radiation effect

Technical field

The utility model relates to a kind of 360 ° of luminous LED garden lightings with excellent heat dispersion performance, belongs to lighting technical field.

Background technology

The LED light emitting diode belongs to cold light source, has advantages such as luminous efficiency height, long service life, has been widely used in various lightings.At present, the LED garden lamp is favored by the consumer very, but because of its illuminator mostly is the LED bulb lamp, and the light that the LED bulb lamp is sent has tangible directionality, thereby there is significant limitation in the range of exposures tool of LED garden lamp.In order to satisfy the requirement of consumer to the garden lamp luminous intensity distribution performance, many manufacturer production go out the illuminator on 360 ° of LED lamp pearls of arranging of cylinder periphery, though this product has solved the limitation problem of illumination to a certain extent, but face a heat radiation difficult problem, this is to use because the lamp holder of garden lamp is mounted in the lampshade, although it is low and have an aluminium radiator that lamp holder itself produces heat, but its heat that distributes still can accumulate in and be difficult in the lampshade discharge, temperature in the lampshade is risen, long-term use will certainly influence the illumination effect of LED, shortens the service life of led chip.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of have excellent heat dispersion performance and 360 ° of luminous LED garden lamps with great heat radiation effect of energy is provided.

The alleged problem of the utility model realizes with following technical proposals:

A kind of LED garden lamp with great heat radiation effect is made up of lampshade, lamp holder and heat radiation lamp socket, and described lamp holder is connected with the heat radiation lamp socket by heat-conducting copper pipe.

Above-mentioned LED garden lamp with great heat radiation effect, described heat radiation lamp socket is made of heat dissipation plate and holder, on lamp stand or lamp stand, described heat dissipation plate is fixed on the holder described holder by bolting, and is connected by the lamp holder of heat-conducting copper pipe with its top.

Above-mentioned LED garden lamp with great heat radiation effect, described lamp holder is made of the LED light emitting module of prismatic radiator and a plurality of strips, fix a LED light emitting module on each side of described prismatic radiator, its lower end is connected by the heat dissipation plate of heat-conducting copper pipe with the heat radiation lamp socket.

Above-mentioned LED garden lamp with great heat radiation effect, described LED light emitting module is made of MC-PCB plate or printed circuit board and welding LED illuminator thereon.

Above-mentioned LED garden lamp with great heat radiation effect is provided with radiating fin around the described heat dissipation plate.

Above-mentioned LED garden lamp with great heat radiation effect, described heat-conducting copper pipe is the U-shaped copper pipe.

The utility model is a light-emitting component with the LED light emitting module that is fixed in a plurality of strips on the prismatic radiator, can make the range of exposures of lamp holder reach 360 °; The lamp holder fansink designs is prismatic, and purpose is the installation of being convenient to the LED light emitting module; Adopt heat-conducting copper pipe to be connected between prismatic radiator and the heat radiation lamp socket, can make the heat of lamp holder generation be delivered to the heat radiation lamp socket rapidly, the heat dissipation plate by the lamp socket that dispels the heat is dispersed in the atmosphere again; Around the heat dissipation plate radiating fin is set, can strengthens radiating effect; Heat-conducting copper pipe is designed to U-shaped, both has been convenient to processing, has increased surface area again, has improved heat transfer efficiency.The utility model not only range of exposures is wide, and has excellent heat dispersion performance, has improved the illuminating effect of LED greatly, has prolonged the service life of led chip.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the schematic perspective view of lamp holder and U-shaped copper pipe.

Each label is among the figure: 1, prismatic radiator; 2, LED light emitting module; 3, lampshade; 4, heat-conducting copper pipe; 5, lead-in wire, 6, heat dissipation plate; 7, holder; 8, fin; 9, set bolt.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3, LED light emitting module 2 of the present utility model can (comprise point-like, planar, strip etc. by any LED illuminator, choose according to different capacity) be welded on MC-PCB plate or the printed circuit board (comprising resin, aluminium, copper, pottery) and make, LED light emitting module 2 is regular list structure, a plurality of LED light emitting modules 2 are fixed on the side of prismatic radiator 1, can make the illumination range of lamp holder reach 360 °.

Heat dissipation plate 6 and prismatic radiator 1 all adopt aluminium to make, after U type heat-conducting copper pipe 4 connects the two, LED light emitting module 2 institute's liberated heat at work is dispersed in the atmosphere through prismatic radiator 1, U type heat-conducting copper pipe 4 and heat dissipation plate 6 successively, and the temperature in the lampshade is reduced.U type heat-conducting copper pipe 4 respectively inserts prismatic radiator 1 and heat dissipation plate 6 interior 2cm pour into tin then.Tin filling has two purposes, and the one, sealing, the 2nd, be easier to heat conduction.

The utility model has not only thoroughly solved the heat conduction and heat radiation problem of 360 ° of emitting led garden lamps, has fundamentally improved the luminous efficacy and the reliability of product, has improved LED service life, has reduced the light fixture cost.And be convenient to realize the multifunction of product, prefabricated and standardization.
