An LED lamp comprises a lamp holder and a screw joint mounted at one end of the lamp holder, a constant current power module is mounted in the lamp holder, a heat sink is mounted on the upper end of the lamp holder, a chuck is mounted on the heat sink, an aluminum substrate with an LED light source is mounted on the chuck, a light-transmitting lampshade is mounted on the aluminum substrate, a plurality of fin grooves are arranged on the outer surface of the heat sink, and the middle position of the heat sink is hollow along the axial direction for accommodating the constant current power module. The utility model has good waterproof performance, strong heat dissipation performance and is easy to assemble.
Description
Technical field
The utility model relates to a kind of light fixture, specifically a kind of LED light fixture.
Background technology
The LED light fixture has that luminous efficiency is high, the characteristics of power saving and long service life, has obtained using more and more widely.In order to reach lighting requirement, a plurality of LED lamps generally are installed in light fixture, therefore, the heat radiation of LED lamp becomes affects LED light fixture use state and a key factor in life-span, especially for high-power LED lamp.The heat radiation of existing LED light fixture is all generally to dispel the heat by fin, and radiating effect is not fine, and whole lamp installation comparatively bothers, and affects production efficiency.
The utility model content
It is good that the technical problems to be solved in the utility model is to provide a kind of thermal diffusivity, and water proofing property is strong, LED light fixture easy to assembly.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of LED light fixture comprises lamp socket and is contained in the screwed union of this lamp socket one end, and described lamp socket is in-built the constant current power module, the attaching of lamp socket upper end has radiator, chuck is housed on radiator, the aluminium base with LED light source is housed on chuck, be set with transparent lamp shade on aluminium base.
Described radiator outer surface is provided with some fin grooves, and the radiator centre position is made as vertically hollow and is used for holding the constant-current supply module.
Also be equiped with silica gel ring between described radiator and chuck, this silica gel ring upper surface contacts with the aluminium alloy chuck, lower surface contacts with radiator.
Described lamp socket and constant-current supply intermodule also are provided with silicagel pad, and this silicagel pad upper surface contacts with the constant-current supply module, lower surface contacts with lamp socket.
Described chuck is the aluminium alloy chuck.
Described transparent lamp shade is that the PC material is made.
Described lamp socket is made by plastic material.
The utility model thermal diffusivity is good, water proofing property is strong, the light that sends is comparatively soft, can not damage human eye, the aluminium alloy chuck can effectively transfer heat to radiator and dispel the heat, and heat can shed to the external world with the form of convection current by the fin groove on radiator, greatly improved heat-sinking capability, make the power can be larger, can substitute outdoor model be that E40/39, power are the workshop Mobile illumination equipment of 500W, energy saving.
Description of drawings
Accompanying drawing 1 is the utility model decomposing state structural representation.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of LED light fixture, comprise lamp socket 2 and be contained in the screwed union 1 of these lamp socket 2 one ends, described lamp socket 2 is in-built constant current power module 4, lamp socket 2 upper end attachings have radiator 6, chuck 8 is housed on radiator 6, the aluminium base 9 with LED light source is housed on chuck 8, be set with transparent lamp shade 10 on aluminium base 9.Radiator 6 outer surfaces are provided with some fin grooves 5, and radiator 6 centre positions are made as vertically hollow and are used for holding constant-current supply module 4.Also be equiped with silica gel ring 7 between radiator 6 and chuck 8, these silica gel ring 7 upper surfaces contact with aluminium alloy chuck 8, lower surface contacts with radiator 6.This silica gel ring 7 effectively plays waterproof action, makes extraneous water be not easy to enter in whole light fixture.In addition, also be provided with silicagel pad 3 at lamp socket 2 and 4 of constant-current supply modules, these silicagel pad 3 upper surfaces contact with constant-current supply module 4, lower surface contacts with lamp socket 2.Further improve water resistance.
Outside drawing, chuck is the aluminium alloy chuck, is convenient to the conduction of heat.Transparent lamp shade is that the PC material of high transmission rate is made, and is used for filtering light, guarantees that the light that light fixture sends can be too not strong, makes light softer, can not damage human eye.Lamp socket is made by plastic material.The wire of constant-current supply module passes silicagel pad and is connected with screwed union.
The heat that the LED lamp produces is delivered on aluminium base, be delivered to again on the aluminium alloy chuck, the aluminium alloy chuck is delivered to heat on radiator, because the radiator periphery design becomes fin groove shape, heat dispels the heat away with the form of convection current by the fin groove, improve heat-sinking capability, extended the service life of whole light fixture.
