Abstract

A lamp comprises a lamp housing and a lampshade combined with the lamp housing, wherein the lamp housing is provided with a light-emitting diode, a through hole is formed in the lamp housing, a through hole corresponding to the through hole in the lamp housing is formed in the lampshade, and heat generated by the LED is directly dissipated outside the lamp through the through hole of the lamp housing and the through hole of the lampshade. Due to the fact that the heat generated by the LED of the lamp can be directly dissipated outside the lamp through the through hole of the lamp housing and the through hole of the lampshade, heat of the lamp can be dissipated out faster, and heating dissipating efficiency of the lamp is improved.

Description

Light fixture

Technical field

The present invention relates to lighting field, especially a kind of light fixture.

Background technology

Light emitting diode (light-emitting diode, LED), Organic Light Emitting Diode (OLED) industry is one of industry attracting most attention in recent years, be developed so far, LED and OLED rely on its high light efficiency, low energy consumption, the advantage such as pollution-free, be applied among increasing occasion, had greatly the trend that replaces conventional light source.Once yet because the heat that the luminescent device such as LED, OLED produces when luminous is piled up, there is the problem of red shift in the wavelength of light that can cause luminescent device to send, and can cause the problem shortening service life.Therefore, must dispel the heat to light fixture.Yet due to stopping of lamp housing, the heat that light source produces is confined in lamp housing, causes radiating effect not good.

Summary of the invention

In view of this, be necessary to provide a kind of light fixture with excellent heat dispersion performance.

A kind of light fixture, comprise lamp housing and the lampshade combining with this lamp housing, this lamp housing is provided with light emitting diode, on this lamp housing, offers through hole, this lampshade is offered the through hole corresponding with through hole on lamp housing, and the heat that light emitting diode sends is directly dispersed into light fixture outside by the through hole of lamp housing and lampshade.

The heat that the light emitting diode of light fixture of the present invention sends, owing to can being directly dispersed into light fixture outside by the through hole of lamp housing and lampshade, can make the heat on light fixture leave quickly, has improved the radiating efficiency of light fixture.

The following specific embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.

The specific embodiment

Refer to Fig. 1, show the exploded view of light fixture 100, light fixture 100 comprises a lamp housing 10 and a lampshade 20.On this lamp housing 10, be provided with some light emitting diodes 13, this lampshade 20 covers at the one side that this lamp housing 10 is equiped with light emitting diode 13 and forms this light fixture 100.

This lamp housing 10 is roughly a rectangle plate body shape, and its middle part offers two surperficial strip through holes that run through on its thickness direction.In the present embodiment, this lamp housing 10 comprises two first through holes 11 and two second through holes 12.This two second through hole 12 of the Length Ratio of these two first through holes 11 is long.This four-way hole 11,12 is side by side the centre that a horizontally-arranged shape is distributed in this lamp housing 10 on its length direction, and the long limit in this four-way hole 11,12 and the long limit of lamp housing 10 parallel.These two second through holes, 12 head and the tail are every establishing, and this two first through hole 11 is arranged at respectively the head and the tail of these two second through holes 12.This first through hole 11 is similar to these the second through hole 12 shapes, is two long limits parallel and equal, and two minor faces are circular-arc strip.And the width of this first through hole 11 and this second through hole 12 is all much smaller than its length.These some light emitting diodes 13 are arranged at the both sides in four-way hole 11,12, and are two row's alignment relative formulas arrangements.

See also Fig. 2, show another angular views of this lampshade 20.The profile of the profile of this lampshade 20 and this lamp housing 10 matches.These lampshade 20 peripheries are coated by the barricade 25 vertically extending towards the direction of lamp housing 10.The height of this barricade 25 is slightly larger than or equals the thickness of lamp housing 10.When lampshade 20 is during with lamp housing 10 combination, four borders of barricade 25 laminating lamp housings 10, and jointly form a receiving space and accommodate light emitting diode 13.In barricade 25, also comprise one with the fixed edge 26 of barricade 25 parallel distributions.The height of this fixed edge 26 approximates greatly the height of light emitting diode 13, and is not more than the height of barricade 25.On fixed edge 26, offer a plurality of for lampshade 20 being fixed on to the fixing hole 24 on lamp housing 10.In the middle of this lampshade 20, offer through hole.In the present embodiment, lampshade 20 offers two first through holes 21 and two second through holes 22 in the four-way hole 11,12 of corresponding lamp housing 10.And two first through holes 21 of lampshade 20 and two second through holes 22 arrange position and shape identical with two first through holes 11 and two second through holes 12 of lamp housing 10.This four-

way hole

21,22 by a retainer ring 27 around.This retainer ring 27 is around the periphery of each through hole 21,22.The height of this retainer ring 27 is less than the height of this barricade 25.When lampshade 20 combines with lamp housing 10, this retainer ring 27 does not contact this lamp housing 10.This lampshade 20 also comprises that some lens 23 are distributed in the both sides in this four-way hole 21,22.Each light emitting diode 13 on the corresponding lamp housing 10 of each lens 23.These lens 23 are integrated when this lampshade 20 is manufactured.The light modulation materials such as fluorescent material also can be mixed in these lens 23 inside.

During light fixture 100 assembling, lampshade 20 and lamp housing 10 combinations, screw is by this fixing hole 24 sealed this lampshade 20 and this lamp housing 10.Lens 23 covers of lampshade 20 are established the light emitting diode 13 of this lamp housing 10.The four-way hole 11,12 of lamp housing 10 is aimed in the four-

way hole

21,22 of lampshade 20, forms the heat dissipation channel connecting.Because the height of the retainer ring 27 in the four-

way hole

21,22 around lampshade 20 is less than the height of barricade 25, therefore after lampshade 20 combines with lamp housing 10, barricade 25 is the surface of the diode installed 13 of butt lamp housing 10 not, makes the receiving space that lampshade 20 and lamp housing 10 enclose jointly pass through each through

hole

11,12,21,22 and the extraneous conducting of light fixture 100.The heat producing when therefore, light emitting diode 13 is worked can directly be dispersed into the external world by the four-

way hole

21,22 of this lampshade 20 and the four-way hole 11,12 of lamp housing 10.Further, due to the through hole the 21,22,11, the 12nd of lampshade 20 and lamp housing 10, upper and lower corresponding perforation arranges, therefore can form stack effect, make hot-air discharge (set light fixture 100 in use lamp housing 10 be positioned at the top of lampshade 20) from the through hole 11,12 of lamp housing 10, cold air enters from the through

hole

21,22 of lampshade 20, thus improving heat radiation efficiency.Owing to being mixed with light modulation material in these lens 23, therefore from light colour temperature after lens 23 of light emitting diode 13 outgoing, be changed again, make it more meet lighting demand.It is integrated when this lampshade 20 is manufactured having these lens 23 again, the step of therefore having saved other production lens 23 and assembling lens 23.
