Abstract
The utility model discloses a LED pendent lamp with efficient heat sink so disposed that the LED pendent lamp herein comprises a fixing base (1) which is provided with a driving power supply (2), wherein the fixing base (1) is provided with at least one messenger wire (8) therebelow, the messenger wire (8) being connected to a lamp holder (3) at the bottom thereof, a lead (9) which extends along the messenger wire (8) being arranged between the fixing base (1) and the lamp holder, the lamp holder being provided with a substrate (4) which is provided with a plurality of LEDs (5), the LEDs being electrically connected to the driving power supply through leads, the lamp holder being provided with a radiator (6) which is connected to a substrate in the rear portion thereof. Heat generated from powering up the LEDs is transmitted through the substrate to the radiator which is characterized by large exposure and large thermal capacity, thereby achieving a slow climb of the temperature of LEDs. Besides, the large surface area of the radiator and the consequent large contact area with air can achieves a quick radiation of heat of the radiator.
Description
Technical field
The utility model belongs to the technical field of lighting, specifically is meant a kind of LED pendent lamp.
Background technology
At present, LED has advantages such as energy-saving and environmental protection, life-span length, has been widely used on the various light fixtures, also has on pendent lamp and adopts the application of LED as light source.Because LED particularly great power LED can produce a large amount of heats when work, can not in time distribute as heat, the limit value if the PN junction temperature is above standard, LED will aggravate light decay, lowers efficiency, even quits work, and the life-span of LED also can be affected.Solve the quick heat radiating problem of LED pendent lamp, the heat that PN junction is produced can distribute as soon as possible, not only can improve the luminous efficiency of pendent lamp, reliability and the life-span that also can improve pendent lamp simultaneously.Therefore, but provide a kind of a kind of LED pendent lamp that dispels the heat good of quick heat radiating to become the industry technical issues that need to address.
Summary of the invention
But the purpose of this utility model is to provide the LED pendent lamp of a kind of quick heat radiating, light efficiency height, long service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of LED pendent lamp that dispels the heat good, comprise holder, be provided with driving power in the holder, the below of described holder is provided with at least one messenger wire, the bottom of messenger wire is connected with lamp holder, be provided with the lead that extends along messenger wire between holder and the lamp holder, be provided with substrate in the described lamp holder, substrate is provided with several LED, LED is electrically connected with driving power by lead, and the rear portion of described lamp holder is provided with the radiator that is connected with substrate.
Described radiator is a column, and its side face is evenly equipped with fin.
Be provided with base plate between described substrate and the radiator.
Be provided with heat-conducting silicone grease between the contact-making surface of described substrate and radiator.
Between described substrate and the base plate, be provided with heat-conducting silicone grease between radiator and the base plate.
The below of described holder is provided with three messenger wires, and the bottom of each root messenger wire is connected with lamp holder respectively.
Owing to adopted above-mentioned structure, radiator major part of the present utility model to be exposed to the outside, the heat that LED energising back produces can conduct on the radiator through substrate, because the radiator heat capacity is big, so the temperature rise speed of LED is slower; In addition, because the surface area of radiator is big, its area that contacts with air is also big, so radiating rate is also very fast, can apace heat be distributed.In sum, the utility model can reduce the operating temperature of great power LED fast, prolongs its working life, has the light efficiency height in addition, and is easily manufactured, and advantages such as low cost of manufacture have very strong practicality and promotional value.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of three-dimensional installation diagram of the LED pendent lamp that dispels the heat good.
The specific embodiment
As shown in Figure 1, a kind of LED pendent lamp that dispels the heat good described in the utility model comprises holder 1, and holder 1 is provided with support 10, and support 10 is used for being connected with ceiling.Be provided with driving power 2 in the holder 1, the below of described holder 1 is provided with at least one messenger wire 8, and the bottom of messenger wire 8 is connected with lamp holder 3, and lamp holder 3 housings are made of last ring and following ring.The below of the described holder 1 among the embodiment is provided with three messenger wires 8, and the bottom of each root messenger wire 8 is connected with lamp holder 3 respectively.Be provided with the lead 9 that extends along messenger wire between holder 1 and the lamp holder 3, be provided with substrate 4 in the described lamp holder 3, substrate 4 is provided with several LED5, and LED5 is electrically connected with driving power 2 by lead 9, and the rear portion of described lamp holder 3 is provided with the radiator 6 that is connected with substrate 4.The heat that LED energising back produces can conduct on the radiator through substrate, because the radiator heat capacity is big, so the temperature rise speed of LED is slower; In addition, because the surface area of radiator is big, its area that contacts with air is also big, so radiating rate is also very fast, can apace heat be distributed.Described radiator 6 is made by the good material of heat conduction such as aluminium, is shaped as cylindricly, and its side face is evenly equipped with fin, and fin can increase the area that radiator contacts with air, further strengthens radiating efficiency.Be provided with heat-conducting silicone grease between the contact-making surface of described substrate 4 and radiator 6, the effect of heat-conducting silicone grease is to increase heat transfer efficiency.Be provided with base plate 7 between described substrate 4 and the radiator 6, base plate 7 is used for radiator 6 is fixed on lamp holder 3, and base plate 7 is made by the good material of heat conduction such as aluminium, is shaped as the disk shape.Between described substrate 4 and the base plate 7, be provided with heat-conducting silicone grease between radiator 6 and the base plate 7, the effect of heat-conducting silicone grease is the heat transfer efficiency that increases between the three.
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
