Abstract

The utility model relates to a light-emitting diode (LED) mining lamp shell body which can greatly improve a heat dissipation effect of an LED mining lamp so as to meet a heat dissipation requirement of the LED mining lamp. The LED mining lamp shell body comprises a heat sink. Cooling fins in shape of straight-strip and sheet are arranged at even interval on a side panel of the heat sink, panels of two sides of the cooling fins are in concave-convex wrinkle shape, and panel bodies of the cooling fins are hollow. As a result, the wrinkle-shaped panels increase a heat dissipation area and the hollow panel bodies are beneficial to heat dissipation of the cooling fins. Therefore, the heat dissipation effect of the shell body is improved, and heat dissipation of the LED mining lamp and especially a high-power LED mining lamp is effectively guaranteed.

A kind of LED bulkhead lamp capable housing

Technical field

The utility model relates to lighting field, is specifically related to a kind of LED bulkhead lamp capable housing.

Background technology

The LED bulkhead lamp capable is the light fixture that uses in the production operation district of factory, mine, and it can be divided into conventional light source bulkhead lamp capable (such as the sodium vapor lamp bulkhead lamp capable, mercury vapor lamp bulkhead lamp capable etc.) and LED bulkhead lamp capable according to light source.Wherein, the LED bulkhead lamp capable is with advantages such as its high light efficiency and low energy consumption and be widely used.Existing LED bulkhead lamp capable mostly is spot light and is polymerized, because the light-emitting area of a single point light source is narrow, usually with its large-scale integrated in the circuit board, whole formation led light source assembly to form a larger light emitting source, embodies its illuminating effect thus.The LED bulkhead lamp capable generally comprises led light source assembly and heat abstractor at present, heat abstractor comprises heat sink, one lateral plates and led light source component joint arrange, its opposite side vertical or tilt its plate towards outside the fin of postponing, be provided with for the installing hole that power shelf is installed in this lateral plates simultaneously, wherein to be vertical bar lamellar for fin, and the interval is evenly arranged between each fin.Like this, straight plate-shaped fin is easy to make and processing really, also is beneficial to its integral body simultaneously and consists of the ventilation channel.Yet the radiating effect of this straight plate-shaped fin is still limited, still can't satisfy its heat radiation requirement for the high-power LED bulkhead lamp capable.

Summary of the invention

The purpose of this invention is to provide a kind of LED bulkhead lamp capable housing, can significantly improve the radiating effect of LED bulkhead lamp capable, to satisfy the heat radiation requirement of LED bulkhead lamp capable (especially high-power LED mine lamp).

For achieving the above object, the utility model has adopted following technical scheme, a kind of LED bulkhead lamp capable housing comprises heat sink, the interval evenly arranges the laminal fin of vertical bar on the side plate face of heat sink, its biside plate face of fin is concavo-convex alternate accordion, and the plate body of fin is hollow form.

Described heat sink is in the form of annular discs, and the core place of heat sink is provided with through hole.

Described fin annular array is on heat sink.

Described fin comprises three kinds of length of long, medium and short and is evenly distributed on successively on the card of heat sink.

The interior outside of described fin is male and fomale(M﹠F).

Described heat sink upper vertical plate face is provided with support and bearing, and support and bearing are offered respectively installing hole, screwed hole.

Described heat sink is comprised of inner panel and outside plate, and described fin extends outside plate by inner panel.

Be evenly equipped with louvre between described inner panel and the outside plate.

By above technical scheme, the plate face of accordion has increased the area of dissipation of fin, the plate body of hollow form is the ventilation and heat that is conducive to fin, thereby has improved the radiating effect of housing, for the heat radiation of LED bulkhead lamp capable especially high-power LED mine lamp provides effective guarantee.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

A kind of housing of LED bulkhead lamp capable comprises heat sink 10, and the interval evenly arranges the laminal fin 11 of vertical bar on the heat sink 10, and fin 11 its biside plate faces vertically are concavo-convex alternate accordion, and the plate body of fin 11 is hollow form.Specifically, these concavo-convex alternate parts all are one to one on the plate body of fin 11, the accordion plate body of fin 11 can increase the contact area of fin 11 and surrounding air, improve heat radiation, fin 11 is little in the gap of recess, and is large in the gap of protuberance, the slit of the hollow in the plate body, help the circulation of air, the thermal diffusivity of the fin that further improves.

Described heat sink 10 is in the form of annular discs, and the core place of heat sink 10 is provided with through hole 14.The benefit of design can make things convenient for the layout of LED lamp group on the one hand like this, guarantees the attractive in appearance of bulkhead lamp capable profile, has also increased on the other hand the contact area of whole radiating shell and air, be conducive to heat radiation, and through hole 14 has improved the ventilation and heat of heat sink 10 more.

Corresponding with the exterior contour of heat sink 10, described fin 11 annular arranged in arrays on heat sink 10.Heat sink 10 fin 11 that arrange as much as possible can be carried the radiating effect that improves whole radiating shell.

Described fin 11 comprises three kinds of length of long, medium and short and is evenly distributed on successively on the card of heat sink 10.Adopt the fin 11 of three kinds of different lengths to be arranged in order setting, not only can increase the gap between the fin 11, and the fin 11 of three kinds of different lengths can form heat dissipation channel in plate face slave plate face central authorities to the plate face outer rim of heat sink 10, strengthen air flow property, more be conducive to heat radiation.

Fin 11 longitudinal cross-sections are frustum, the affixed heat sink 10 plate faces of its large end, and 10 of fin 11 and heat sinks are one-body molded.Guarantee that so not only fin 11 and surrounding air contact area are larger, improved the also just inevitable further increase of its radiating efficiency, and fin 11 is one-body molded with heat sink 10, makes processing technology simpler, radiating effect is more outstanding.

For the ease of the installation of power supply and the angle adjustment of housing, described heat sink 10 upper vertical plate faces are provided with support 12 and bearing 13, support 12 and bearing 13 offer respectively installing hole 121 and screwed hole 131.Specifically, the effect of bearing 13 mainly is Power Support, and for example the shell of motor is fixed on motor housing on the screwed hole 131 by bolt; The effect of support 12 is to connect machine shaft, so just can regulate by motor the rotational angle of rotating shaft, drives the rotation of whole housing, realizes the adjusting of the irradiating angle of LED bulkhead lamp capable.

For the ease of the installation of fin 11, also can improve the radiating effect of heat sink 10 and fin 11 simultaneously, described heat sink 10 is comprised of inner panel 101 and outside plate 102, and described fin 11 extends outside plate 102 by inner panel 101.

Further, be evenly equipped with louvre 103 between described inner panel 101 and the outside plate 102, so just can greatly improve the thermal diffusivity of heat sink 10.
