Abstract

The utility model relates to an LED (Light-Emitting Diode) luminaire and particularly relates to a light-equalizing and cooling LED lamp. A lamp panel is fixedly arranged in a socket ring; the socket ring is connected with a lamp shade; the socket ring is arranged on a lamp body; a hollow cavity which serves as a power supply cavity is arranged in the lamp body; a driving power supply board is arranged in the power supply cavity; and lamp holder and cooling fins are fixedly arranged on the lamp body. With the adoption of the structure, seven lamp beads are arranged on the lamp panel and respectively arranged at six vertexes and one center point of a regular hexagon, therefore, the lighting can be more equal, and the lighting effect of the LED lamp is improved; the arc-shaped cooling fins are arranged on the side surface of the lamp body, and the lamp body is a frustum, therefore, a circle of spiral cooling fin group is finally defined by the cooling fins, so as to be beneficial to the air flow, furthermore, the cooling area is bigger, thereby being more beneficial to cooling; and, in order to prevent key components from being influenced by high temperature, a cooling pad is arranged between the socket ring and the lamp panel, and the cooling pad can timely reduce the temperature of the lamp panel so as to effectively protect the lamp panel.

Description

LED spares the light thermal louver

Technical field

The utility model relates to a kind of LED light fixture, and especially a kind of LED spares the light thermal louver.

Background technology

Illuminations is seen everywhere in our daily life, and illuminations is applied in a lot of aspects, throws light on such as interior decoration: wall lamp, pendent lamp, corner lamp, anomaloscope etc.; Special-purpose general lighting: low-level lighting (lamp is used in corridor lamp, doorplate lamp, front yard), microscope lamp, desk lamp etc.; Emergency lighting: mine lamp, explosion-proof lamp, green indicating lamp, emergency light; General lighting: office, shop, hotel, home-use general lighting lamp though the LED illuminations has certain application within the specific limits, are not very extensive; This mainly contains some reason, because principle of luminosity and traditional gaffer of LED lamp have tangible difference, LED (Light Emitting Diode); Being light emitting diode, is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity; The heart of present LED lamp pearl is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole; The other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer through lead, electronics will be pushed to the P district, and electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in the P district.And the light wavelength color of light just is by the material decision that forms the P-N knot.

And present LED lamp is by several or a plurality of lamp pearl illuminated in combination; Therefore be easy to occur the phenomenon of luminance nonuniformity; Though the heat that the LED lamp produces in use is far smaller than the heat that conventional lamp produces; But still can produce great amount of heat after long-term the use, because temperature rising meeting has harmful effect to wiring board and the parts of LED.

Summary of the invention

The utility model provides a kind of LED even, rapid heat dissipation simple in structure, luminous even light thermal louver.

The utility model solves the technical scheme that its technical problem adopted: a kind of LED spares the light thermal louver, comprises lampshade, lamp plate, lamp body, driving power plate, lamp socket, fin, it is characterized in that also comprising the collar; Lamp plate is fixedly installed in the collar; The collar is connected with lampshade, and the collar is arranged on the lamp body, is provided with cavity in the lamp body as power source cavity; The driving power plate is arranged in the power source cavity, and lamp socket, fin all are fixedly installed on the lamp body.

Further being set to of the utility model: said lamp body is a frustum, and fin is fixedly installed on the side surface of frustum, and fin is an arc-like sheet, and fin is arranged on the frustum side surface equably.

Further being set to of the utility model: also comprise seven lamp pearls, the lamp pearl is arranged on the lamp plate, is separately positioned on orthohexagonal six summits and the central point.

Further being set to of the utility model: also comprise cooling pad, cooling pad is sticked on the collar, is clipped between the lamp plate and the collar.

Said structure is provided with 7 lamp pearls on lamp plate, be separately positioned on orthohexagonal 6 summits and the central point, so just can make illumination more even; Improve the lighting effect of LED lamp, the fin of arc is set on the side surface of lamp body, because lamp body is a frustum; Therefore fin finally is the groups of fins that has surrounded a circle spiral, be beneficial to flowing of air-flow, and area of dissipation is bigger; Be more conducive to heat radiation, receive temperatures involved, between the collar and lamp plate, cooling pad is set in order to prevent critical component; Cooling pad can in time reduce the temperature of lamp plate, effectively protects lamp plate.
