Abstract
The utility model discloses a heat dissipation structure for an LED (light-emitting diode) lamp, which solves the problems in heat dissipation of the LED lamp and comprises a light source, a heat conducting fin, a light source fixing bracket, and a lamp barrel, wherein the lamp barrel is hollow and is provided with a bottom wall; one side of the heat conducting fin is pasted onto the back surface of the light source; the other side of the heat conducting fin is pasted onto the bottom wall of the lamp barrel; and the light source is fixed on the inner side of the lamp barrel by the light source fixing bracket. In the heat dissipation structure, the heat conducting fin is adopted for heat conduction between the light source and the lamp barrel, so that the heat of the light source is conducted to the lamp barrel quickly; the lamp barrel is in large-area contact with air so as to facilitate heat dissipation; and the heat dissipation structure for the LED lamp achieves high-efficiency heat dissipation with simple structure and low cost.
Description
Technical field
The utility model relates to the LED lighting technical field, is specifically related to the LED lamp cooling structure.
Background technology
Advantages such as LED has high brightness, power consumption is low, and service life is long, traditional lighting light fixture such as it is replace incandescent gradually, fluorescent tube and become the light source of a new generation.Present LED light fixture also has weak point, and the LED caloric value is big, when LED heat radiation is not enough, can cause the led chip temperature to rise rapidly influencing its life-span, and is serious even can burn out.Therefore solving the LED heat radiation is the long-life prerequisite of LED.Existing LED light fixture generally adopts the aluminum radiating fin, and cost is high, and radiating effect is general, influences the LED light fixture and popularizes.
The utility model content
The utility model provides a kind of LED lamp cooling structure, can solve the heat dissipation problem of LED light fixture and practice thrift more cost.
The utility model provides a kind of LED lamp cooling structure; Comprise: light source, conducting strip, light source fixing frame, lamp tube; Lamp tube hollow and have diapire; The one side of conducting strip is attached to the back side of light source, and the another side of conducting strip is attached on the diapire of lamp tube, and light source fixing frame is fixed on lamp tube inboard with light source.
Preferably, the lamp tube adopts aluminium lamp tube.
Preferably, light source fixing frame is set on the light source after by forward direction, and it is inboard to be fixed on the lamp tube through screw.
Preferably, the conducting strip two sides all scribbles heat-conducting glue.
Technique scheme can be found out; Because the utility model embodiment adopts light source and lamp tube to carry out the heat conduction through conducting strip; Thereby the heat of light source is passed to the lamp tube fast; The lamp tube contacts with the air large tracts of land, helps heat and scatters and disappears, and the simple structure of LED lamp cooling structure utilization of the utility model embodiment, less cost realize heat radiation efficiently.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the blast structure chart of LED lamp cooling structure among the utility model embodiment.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment:
The utility model embodiment provides a kind of LED lamp cooling structure; As shown in Figure 1; Comprise light source 3, conducting strip 2, light source fixing frame 4, lamp tube 1, lamp tube 1 hollow and have diapire, the one side of conducting strip 2 is attached to the back side of light source; The another side of conducting strip 2 is attached on the diapire of lamp tube 1, and light source fixing frame 4 is fixed on light source 3 inboard of lamp tube 1.
Particularly, lamp tube 1 adopts aluminium lamp tube, has good heat transfer performance.Light source fixing frame 4 is set on the light source 3 after forward direction is arranged, and light source fixing frame 4 is fixed on lamp tube inboard through screw.Light source fixing frame 4 can be good at preventing that light source and conducting strip from coming off from the lamp tube, and certainly, the fixed form between light source fixing frame and the lamp tube can also have multiple mode; For example in the upper shed of lamp tube; Hook is set on the light source fixing frame, and light source fixing frame is articulated on the lamp tube, perhaps between lamp tube and light source fixing frame, adds shell fragment and fixes; Therefore, should not constitute restriction for the fixed form between light source fixing frame and the lamp tube to the utility model protection domain.In order to increase light source and conducting strip, and the heat transfer performance between lamp tube and the conducting strip, all coat heat-conducting glue on the conducting strip two sides, heat-conducting glue can be selected existing silica gel for use.
Compare with existing LED lamp cooling structure; LED lamp cooling structure among the utility model embodiment is with the heat transferred lamp tube that produces on the light source; And the contact area of lamp tube and air is bigger, thereby can quicken heat radiation, and the assurance led light source is worked in reasonable temperature.
More than LED lamp cooling structure that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the core concept of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
