Abstract

The utility model provides an LED lighting lamp appliance honeycomb radiator, comprising a fixed board, a lamp board and a radiating fin arranged between the fixed board and a lamp board and fixed by a connection piece. The two ends of the radiating fin pass through a bar hole on the fixed board and is bent. The bottom part of the LED on the lamp board is contacted with the radiating fin, wherein, the radiating fin is provided with a piece or a group. When the radiating fin is provided with a group, included angles are arranged between the bending parts of the radiating fins. A fixed board can be provided with a plurality of lamp boards and the quantity of the radiating fins can be selected according to the LED power. The utility model is of simple structure, convenience for use, low cost, good commonality and good radiation and is applicable to lamp appliance which is provided with LED as a light source.

Description

LED lighting beehive type radiator

Technical field

The utility model relates to a kind of heat abstractor of lighting source, particularly relates to a kind of LED lighting beehive type radiator.

Background technology

Led light source can generate heat when electrified light emitting, produces higher temperature, and can only bear the highest about 60 ℃ temperature during the long-term work of led light source own, if surpass this temperature during work, can shorten its service life, and light decay increases severely, even damages.Because led light source is applied to still new industry of illumination, the subject matter when its concrete application is to solve heat dissipation problem.And the traditional heat-dissipating device is to design according to concrete application feature, and the size relative fixed use underaction, and cost is higher, when product difference or identical product moulding not simultaneously, radiator can not be general.The radiating mode that some producer is used for LED is by the fan forced heat radiation, and this mode cost height, and fault rate height use inconvenient.

Goal of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of good heat dissipation effect is provided, applying flexible and lower-cost LED lighting beehive type radiator.

Summary of the invention

The utility model LED lighting radiator comprise fixed head, lamp plate and be arranged on lamp plate and fixed head between fin, the three is fixed together by connector.Each lamp plate is provided with a LED installing hole, and its bottom contacted with fin after LED was installed on the lamp plate.Bar hole and the bending on the fixed head passed at its two ends of fin between lamp plate and fixed head.Fin can be a slice, also can be by one group that constitutes more than two, and general one group is 2～4.When fin is one group, between each fin dogleg section angle is arranged, more help the heat bamboo telegraph in air.Reduce the LED temperature fast.Fin is generally the sheet metal of 0.3～2.0mm thickness, can several fin be superposed to one group according to the size of LED power, and the radiator that needn't more renew again just can satisfy the heat radiation requirement.Fixed head is to have other material that the metallic plate of certain intensity or hear resistance and intensity can meet the demands, can several LED be set according to the requirement of light fixture on same fixed head, several lamp plates promptly are set on fixed head, a LED is installed, the corresponding a slice of each LED or one group of fin on each lamp plate.

The operation principle of the utility model LED lighting radiator is that a LED is installed on the lamp plate, and the heat that produces during the LED energising passes to fin by the LED bottom, and propagates in the air by fin again, thereby keeps the normal serviceability temperature of LED.

The advantage of the utility model LED lighting radiator is simple in structure, applying flexible, according to heat radiation require that fin can for a slice or by several groups of constituting, cost be low, versatility is good, good heat dissipation effect.

The specific embodiment

The utility model LED lighting radiator comprise fixed head 1, lamp plate 5 and be arranged on lamp plate 5 and fixed head 1 between fin 4, fin 4 is two, the three is fixed together by screw 2.A LED3 is installed on each lamp plate 5, and its bottom contacted with fin 4 after LED3 was installed on the lamp plate 5.Bar hole 5 and the bending on the fixed head 1 passed at fin 4 its two ends between lamp plate 5 and fixed head 1, and dogleg section has angle à.

Claims

1. a LED lighting beehive type radiator comprises fixed head and lamp plate, it is characterized in that lamp plate is provided with the LED installing hole, is provided with fin between lamp plate and the fixed head, and by connector the three is fixed.

2. LED lighting beehive type radiator as claimed in claim 1 is characterized in that the fin two ends pass bar hole and the bending on the fixed head.
