The heat dissipation substrate is mounted in the lamp holder, heat dissipation fins and a support thermal conducting ridge are arranged on the back face of the lamp holder, a plurality of heat dissipation holes are formed in the heat dissipation substrate, and thermal conducting metal rings used for dissipating heat are embedded in the inner walls of the heat dissipation holes. The lamp has a great heat dissipation effect.

Description

A kind of light fixture

Technical field

The utility model relates to a kind of light fixture, relates in particular to a kind of LED light fixture.

Background technology

LED is the abbreviation of English Light Emitting Diode, and namely light emitting diode is a kind of semiconductor solid luminescence device.LED can be visible light with electric energy conversion, it has changed the luminous principle luminous with the energy-saving fluorescent lamp tricolor powder of incandescent lamp tungsten filament, and the employing electroluminescence has that luminous efficiency is high, a little power consumption, service life is short, control circuit is simple, luminous uniformity is high characteristics.Along with the proposition of " energy-conservation " and " green illumination " theory, LED is incorporated in the lighting gradually as light source.

At present, in the prior art, the light emitting source that the normal lighting light fixtures such as daily bulb, desk lamp adopt is as main basically take incandescent lamp bulb or fluorescent tube, yet the electro-optical efficiency of incandescent lamp bulb and fluorescent lamp tube is all lower, and its heat is large, service life is short, generally only has about 3000 hours.Because the significant advantage of LED, some have also appearred on the market with the bulb of LED as light source, these bulbs only are to form at the peripheral directly sheathed lampshade of LED, its radiating effect is not good, and, aggravated the accumulation of heat of LED lamp in the prior art for the hermetically-sealed construction that reaches the waterproof and dustproof effect, this has shortened the service life of light fixture greatly.

Therefore, providing a kind of light fixture of good heat dissipation effect is the technical problem that those skilled in the art need solution badly.

The utility model content

A purpose of the present utility model provides a kind of light fixture of good heat dissipation effect.

To achieve these goals, the utility model provides a kind of light fixture, comprise lamp socket, lampshade, heat-radiating substrate and LED, described LED is packaged on the described heat-radiating substrate, and being lined with the heat conduction film, described heat-radiating substrate is installed in the lamp socket, is provided with radiating fin on the lampshade back side and supports the heat conduction ridge, described lamp socket is provided with a plurality of louvres, is embedded with the heat-conducting metal circle for heat radiation on the inwall of described louvre.

Preferably, described heat-radiating substrate is strip.

Preferably, be provided with heat dissipation channel between described lamp socket and the described heat-radiating substrate.

Compared with prior art, light fixture provided by the utility model, its described LED is packaged on the described heat-radiating substrate, and be lined with the heat conduction film, described heat-radiating substrate is installed in the lamp socket, be provided with radiating fin on the lampshade back side and support the heat conduction ridge, described lamp socket is provided with a plurality of louvres, is embedded with the heat-conducting metal circle for heat radiation on the inwall of described louvre.

Therefore, radiating fin and cross-ventilation heat radiation by the lampshade back side have increased radiating surface, have improved radiating efficiency; By be provided with a plurality of louvres at lamp socket, be coated with the heat-conducting metal circle for the perforation lamp socket of heat radiation on the inwall of this louvre, strengthened heat dispersion.

In embodiment further preferably, described heat-radiating substrate is strip, therefore, a plurality of LED can be installed, and forms Multi-point luminous, and carries out the multiple spot heat radiation, improves radiating rate.

In embodiment further preferably, be provided with heat dissipation channel between described lamp socket and the described heat-radiating substrate, therefore, can further improve heat dispersion.

Description of drawings

Fig. 1 is the structural representation of a kind of embodiment of a kind of light fixture that the utility model proposes. ?

The specific embodiment

The purpose of this utility model provides a kind of light fixture of good heat dissipation effect.

In order to make those skilled in the art understand better the technical solution of the utility model; below in conjunction with accompanying drawing the utility model is described in detail; the description of this part only is exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.

Please refer to Fig. 1, a kind of be among the embodiment, a kind of light fixture provided by the utility model, comprise lamp socket 1, lampshade 6, heat-radiating substrate 5 and LED, described LED is packaged on the described heat-radiating substrate, and is lined with the heat conduction film, described heat-radiating substrate 5 is installed in the lamp socket 1, be provided with radiating fin 4 on 6 on the lampshade and support heat conduction ridge 3, described lamp socket 1 is provided with a plurality of louvres 7, is embedded with the heat-conducting metal circle for heat radiation on the inwall of described louvre 7.

Therefore, radiating fin 4 and cross-ventilation heat radiation by lampshade 6 back sides have increased radiating surface, have improved radiating efficiency; By be provided with a plurality of louvres 7 at lamp socket 1, be coated with the heat-conducting metal circle for the perforation lamp socket of heat radiation on the inwall of this louvre 7, strengthened heat dispersion.

Further, described heat-radiating substrate 5 is strip, therefore, a plurality of LED can be installed, and forms Multi-point luminous, and carries out the multiple spot heat radiation, improves radiating rate.

Further, be provided with heat dissipation channel 7 between described lamp socket 1 and the described heat-radiating substrate 5, therefore, can further improve heat dispersion.

Need to prove, in this article, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thereby not only comprise which key element so that comprise process, method, article or the equipment of a series of key elements, but also comprise other key elements of clearly not listing, or also be included as the intrinsic key element of this process, method, article or equipment.In the situation that not more restrictions, the key element that is limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment that comprises key element and also have other identical element.

Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.The above only is preferred embodiment of the present utility model, should be understood that, because the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characterictic can be made up by rights; These improve retouching, change or combination, or without improving the design of utility model and technical scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
