Abstract
The utility model discloses a LED tube light with efficient heat sink so disposed that the LED tube light herein comprises a bottom box (1) which is provided with a middle ring (2) and an outer ring (3), the bottom box (1) being provided with a substrate (4) which is provided with a plurality of LED (5), the outer ring being provided with a spring buckle (6), the rear portion of the bottom box being provided with a radiator (7), the substrate and the inner surface of the bottom box being tightly connected to each other, the radiator and the outer surface of the bottom box being tightly connected to each other, the radiator being disposed behind the bottom box with a large portion exposed outside. The facts that a large portion of the radiator of the utility model will be exposed outside, and heat generated from powering up of the LED will transmit to the radiator through the substrate, also considering the large thermal capacity of the radiator, the temperature of the LED will rise slowly. Besides, the large surface area of the radiator leads to a large contact area with air, so that radiator can run quickly and radiation of heat can also go quickly. The utility model can quickly reduce working temperature of high power LED, prolong service time, increase light efficiency, and promise practicability and popularization value.
Description
Technical field
The utility model belongs to the technical field of lighting, specifically is meant a kind of LED Down lamp.
Background technology
At present, the LED Down lamp has obtained using comparatively widely, and LED Down lamp on the market adopts great power LED mostly.Great power LED can produce a large amount of heats when work, can not in time distribute as heat, and 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 Down lamp LED, the heat that PN junction is produced can distribute as soon as possible, not only can improve the luminous efficiency of Down lamp, reliability and the life-span that also can improve Down lamp simultaneously.Therefore, but provide a kind of LED Down lamp 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 a kind of quick heat radiating to improve the light efficiency and the LED Down lamp in service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: good LED Down lamp dispels the heat, comprise end box, ring and outer shroud were provided with substrate in the end box during box of the described end was provided with, and substrate is provided with several LED, outer shroud is provided with the elasticity button, the rear portion of box, the described end is provided with radiator, and substrate closely is connected with the inner face of end box, and radiator closely is connected with the outside of end box.
Described radiator is a column, and its side face is evenly equipped with fin.
Be provided with heat-conducting silicone grease between the contact-making surface of described substrate and end box.
Be provided with heat-conducting silicone grease between the contact-making surface of described radiator and end box.
Owing to adopted above-mentioned structure, radiator of the present utility model to be located at box back, the end, the radiator major part is exposed to the outside, and 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, improves light efficiency, has 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 stereogram of the LED Down lamp that dispels the heat good.
Fig. 2 is a kind of three-dimensional installation diagram of the LED Down lamp that dispels the heat good.
The specific embodiment
As depicted in figs. 1 and 2, a kind of LED Down lamp that dispels the heat good described in the utility model comprises end box 1, and end box 1 is made by aluminium.Ring 2 and outer shroud 3 were provided with substrate 4 during box of the described end 1 was provided with in the end box 1, and substrate 4 is provided with several LED5, and LED5 powers by external direct power supply.Described outer shroud 3 is provided with elasticity button 6, and elasticity button 6 is used for the installation of light fixture.The rear portion of box of the described end 1 is provided with radiator 7, and substrate 4 closely is connected with the inner face of end box 1, and radiator 7 closely is connected with the outside of end box 1.Described radiator 7 is made by aluminium, is column, 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 end box 1, be provided with heat-conducting silicone grease between the contact-making surface of described radiator 7 and end box 1, the effect of heat-conducting silicone grease is the heat transfer efficiency that increases between radiator 7, end box 1, substrate 4 threes, increases radiating efficiency.
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.
