Abstract
The utility model relates to an LED lighting lamp, which comprises a lamp cup, a flat-plate arranged on the bottom of the lamp body, an aluminum base plate positioned in the lamp cup and attached on the flat-plate, an LED chip preset on the aluminum plate, and a control circuit which is electrically connected with the LED chip. The utility model is characterized in that radiation pillars which are lower convex are arranged on the bottom of the aluminum base plate, and holes engaging with the radiation pillars are arranged on the flat-plate. The utility model has excellent lighting effect, reasonable structure, and extensive application, which is a lighting lamp with favorable market potential.
Description
Technical field
The utility model belongs to lighting field, refers in particular to a kind of LED illuminating lamp.
Background technology
LED is applied to illumination and the lamp decoration industry reaches its maturity, and along with improving constantly of LED power, it is very important that the heat dissipation problem of LED just becomes.Existing LED light fixture much all is that several LED are closely aligned on an aluminium base, aluminium base is close on the heat-dissipating casing again, solves the problem of heat radiation by the method.For example the Chinese patent notification number is the LED multicore sheet power energy-saving cup of CN2781168Y, and the scheme that this patent adopted is as above-mentioned scheme.Though this scheme can solve the heat dissipation problem of LED to a certain extent, if the LED number is very many, and when being closely aligned very much on the aluminium base, just can not satisfying dispels the heat has required; In addition, all do not mention the connected mode of aluminium base and Lamp cup in this patent document in the whole text, by prior art generally all adopt heat-conducting glue with above-mentioned both be pasted together.When the working time was long, the heat-conducting glue accelerated ageing of being heated can make aluminium base and being connected of Lamp cup become unreliable, thereby aluminium base can break away from the fixed range of Lamp cup, and last whole lamp is also with regard to cisco unity malfunction.
Summary of the invention
The utility model provides a kind of LED illuminating lamp in order to solve the problems of the technologies described above, it has better radiating effect, and syndeton is more reasonable and reliable simultaneously.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of LED illuminating lamp, comprise Lamp cup, described Lamp cup bottom is provided with flat board, be positioned at Lamp cup and be close to aluminium base on the flat board, be preset at the LED wafer on the aluminium base, and the control circuit that is electrically connected with the LED wafer, it is characterized in that described aluminium base bottom is provided with down protruding thermal column, flat board is provided with the hole of matching with thermal column, described thermal column and hole are by being threaded, described flat board is provided with the through hole that passes through for the lead that connects LED wafer and control circuit, between described flat board and the aluminium base heat-conducting glue is arranged, the inwall of described Lamp cup is provided with reflector layer, and the top of described Lamp cup is provided with diffuser.
Compare with described technical scheme in the background technology, the utlity model has following advantage: at first, the utility model increases the structure that thermal column cooperates with the hole on the basis of existing technology, and it is tightr that aluminium base is combined with Lamp cup, it is big that its contact area becomes, and radiating effect is better; Secondly, aluminium base by thermal column more make with the cooperation in hole between them be connected more firm, the reliability increase.
Description of drawings
Fig. 1 is a cut-away view of the present utility model;
The specific embodiment
The utility model mainly comprises Lamp cup 1, aluminium base 2, LED wafer 3, control circuit 4 and joint 5.Contrast Fig. 1, Lamp cup 1 is hollow bucket-shaped, intracavity bottom has a flat board 11, is aluminium base 2 on the flat board 11, presets a plurality of compact arranged LED wafers 3 on the aluminium base 2.Aluminium base 2 closely contacts with dull and stereotyped 11, an available heat-conducting glue adhesion and a cushioning effect between them.Inventive point of the present utility model is, on aluminium base 2, be provided with thermal column 21, and on dull and stereotyped 11, be provided with the hole 12 of matching with thermal column 21, so just make contact between aluminium base 2 and dull and stereotyped 11 more tight, and their contact area is bigger, help heat radiation more, also can play the fixedly effect of aluminium base 2 simultaneously.Further, also can be set to be threaded between thermal column 21 and the hole 12, can further increase the contact area of loosing between them and fixing elasticity.Control circuit 4 is fixed in the cavity of Lamp cup 1, leads to four leads 7 on it, and wherein two are connected UNICOM's external power supply on the joint 5, and other two are connected LED wafer 3 and provide power supply to work to LED.Be provided with through hole 13 on dull and stereotyped 11, can conveniently make provides power supply to pass through to the lead 7 of LED wafer.Joint 5 is bayonet fittings or screw-type joint, on the ordinary incandescent lamp seat.In addition, in order to strengthen illumination effect, be provided with reflector layer at the Lamp cup inwall, the Lamp cup top also has diffuser 6, so that illumination effect is better.
The utility model good illumination effect, rational in infrastructure, applied widely, be a kind of illuminating lamp with fine market potential.
