Description

The die set of LED light fixture

Technical field

The utility model relates to a kind of can Rapid Combination the location and the light fixture of changing the LED module.

Background technology

Little based on volume, power consumption is few, caloric value is low and the characteristic of long service life, adopt at present LED (Light Emitting Diode, light emitting diode) as light source to replace incandescent lamp bulb, based on halogen bulb ... Deng light fixture more and more many.Yet the design of existing LED light fixture is that a substrate that is distributed with circuit is set on lamp socket, with welding manner a plurality of LED is set on this substrate; Therefore, when having only one or several LED to damage in this light fixture to need to change, just need to change the substrate and the LED of whole group; Or also must change whole LED simultaneously during the substrate fault.

Led chip temperature in the LED lighting must be controlled at below 80 ℃, just can convert electrical energy into luminous energy rather than heat energy, thus the low power consuming of performance LED light fixture and characteristics low in calories.Therefore, at the light fixture that uses most LED as light source, promptly must consider cooling and the heat dissipation problem of light fixture when energising.The radiator structure of the LED projecting lamp that the TaiWan, China patent announcement is disclosed for M278217 number discloses that promptly the radiator with plural fin being set in light fixture, enlarge heat absorption and area of dissipation according to this plural number fin, to promote the cooling effectiveness of LED luminescence component; In addition, general light fixture also utilizes the metal of excellent in heat dissipation effect to make lamp housing as far as possible, and at lamp housing plural louvre is set, and the part heat that luminescence component produced is distributed by louvre, and the part heat is directly absorbed by the metal lamp housing, by air this heat is got rid of again.

The utility model content

Problem to be solved in the utility model provides a kind of die set of LED light fixture, to overcome the following defective of prior art:

One, damage as one or a few LED, or have only substrate damage and LED when not damaging, all must change the LED and the substrate of entire module, therefore very uneconomical.

Two, the radiating mode of existing LED lamp is that lamp housing at metal is provided with most louvres, discharges with heating load, thereby has directly reduced the area that absorbs heat, and radiating efficiency can't further be provided.

Three, get rid of heat (promptly so-called " ventilation type ") with air, its cooling effectiveness is also relatively poor.

For achieving the above object, the utility model provides a kind of die set of LED light fixture, the principal character of this die set, be to adopt design of modularization, the LED module that plural number is small-sized is installed in the base, and the speculum lampshade of a panel and plural corresponding those LED modules is installed on base more in regular turn, therefore, when one or a few LED module damage,, can change at the LED module of this damage as long as pull down this panel.

Another feature of this die set, be that base at the LED light fixture is provided with heat abstractor, this heat abstractor can form chamber below base, filling such as cooling fluid, heat-conducting glue in chamber again ... Deng conduction material, high thermal conductivity coefficient by this conduction material conducts heat to the base that possesses good heat conductive character and enlarges area of dissipation, thereby favorable cooling effect is provided; This heat abstractor also can be in conjunction with heat sink or radiating tube, to obtain identical or approximate radiating effect below base.

The utility model is realized the technological means of this LED light fixture die set, includes a base, plural LED module, a panel and plural speculum lampshade, and those LED modules are installed on the bottom surface, interior space of base respectively independently; The panel that is provided with plural lampshade hole then is installed on the interior space opening of base; The mirror lampshade is nested with and is fixed in each lampshade hole of panel more respectively, makes described LED module be positioned at the central authorities of speculum lampshade; By this modular structure; Described base then is provided with interior shell block in an outer shell base, and constitutes a chamber between interior shell block and outer shell base, refills conduction material in this chamber, by this conduction material as conducting heat to the medium that outer shell base dispels the heat again.

Compared with prior art, the utlity model has following advantage:

Each LED module that light fixture of the present utility model comprised is separately independently, and, therefore, damage at the minority light source with the light source of modularity mode as light fixture, can get final product at the unit replacement that damages easily, therefore the utlity model has preferable economy; At this moment, the utility model utilizes the conduction of conduction material auxiliary lamp heat, more makes the radiating effect of the utility model LED light fixture be better than traditional LED light fixture.

The specific embodiment

Following conjunction with figs. and element numbers are done more detailed description to embodiment of the present utility model, can implement after reading this specification for those skilled in the art.

Consult Fig. 1 to Fig. 4, preferred embodiment of the present utility model includes a base 1, a panel 2, plural speculum lampshade 3 and plural led module 4; Wherein, base 1 is further made by the material that possesses good heat conductive character (for example metal such as copper), and can promote cooling effect in conjunction with heat abstractor, the embodiment of this heat abstractor can be provided with chamber 13 below base, be filled with conduction material (for example cooling water, heat-conducting glue etc.) again in chamber; Also can be used to provide heat conduction and radiating effect in conjunction with heat-conducting plate or heat pipe below base.This chamber 13 can be one-body molded making when making base, also can form by 12 groups of structures of shell block in an outer shell base 11 and as shown in Figure 4, interior shell block 12 is located in the shell 11, be used between interior shell block 12 and shell 11, constituting a chamber 13, periphery with chamber is sealed again, leaks to avoid conduction material; Base 1 top that is constituted then forms space 10 in, and bottom surface in space 10 then is provided with a plurality of lamp sockets that are used for installing led module 4 in this.Described led module 4 includes a substrate and a plurality of LED crystal grain that are located on this substrate, is distributed with on this substrate to start the LED circuitry needed.
