Abstract
The utility model relates to an LED (light emitting diode) lamp with high heat radiation performance. The LED lamp comprises a case, wherein the top end of the case is fixedly provided with a lamp head through a lamp head clamp seat, a driving power supply is arranged inside the lamp head, a lamp support frame is arranged inside the case, a plurality of longitudinal support ribs are arranged on the outer surface of the lamp support frame, a plurality of heat radiation passages are formed between the longitudinal support ribs and the inner surface of the case, the bottom end of the lamp support frame is provided with an LED lamp board, the LED lamp board is connected with the driving power supply through a circuit, and a diffusion cover fixedly arranged on the case is arranged under the LED lamp board. The LED lamp with high heat radiation performance has the advantages that the structure is simple, according to the chimney effect, the heat radiation passages are formed between the longitudinal support ribs and the inner surface of the case, and the tops and the bottoms of the heat radiation passages are respectively communicated with outside air, so the air convection is generated, the heat radiated by the LED lamp is taken away, the service life of the LED lamp is prolonged, the temperature inside the LED lamp can be effectively reduced, the heat radiation effect is good, the installation and the maintenance are convenient, and the wide range popularization and application can be realized.
Description
Technical field
The utility model relates to a kind of high heat dispersion LED lamp.
Background technology
LED can be used as a kind of light source of high benefit.Because little, the low power consumption and other advantages of volume, LED is widely used in fields such as automobile, traffic lights indication, screen display even illumination.During as illuminations, the LED lamp is compared its power saving rate with incandescent lamp, fluorescent lamp and can be reached more than 70%.Development along with application demand; Need more and more LED lamps; But existing LED modulated structure is complicated, and installation, easy to maintenance brings the existing simultaneously LED lamp of great inconvenience mainly to rely on light fixture outer wall and air to carry out thermal convection current to the user and dispels the heat; Present this mode can not satisfy high-powered LED lamp heat radiation requirement, the service life of reducing the LED lamp easily.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of high heat dispersion LED lamp simple in structure, easy to use.
The high heat dispersion LED lamp of the utility model comprises shell, and fixedly lamp holder of lamp holder deck is passed through on the top of said shell; The inside of lamp holder is provided with driving power, and the inside of shell is provided with lamp bracket, and the outer surface of lamp bracket is provided with a plurality of longitudinal bracing muscle; Form a plurality of heat dissipation channels between the inner surface of longitudinal bracing muscle and shell; The bottom of lamp bracket is provided with the LED lamp plate, and the LED lamp plate is connected with driving power through circuit, and the below of LED lamp plate is provided with the diffusion shell that is fixed on the shell.
The high heat dispersion LED lamp of the utility model is provided with the diffusion retainer plate between said shell and the diffusion shell.
The high heat dispersion LED lamp of the utility model, the outer surface of said lamp holder is provided with external screw thread.
Compared with prior art the beneficial effect of the utility model is: the high heat dispersion LED modulated structure of the utility model is simple, according to stack effect, between the inner surface of longitudinal bracing muscle and shell, forms a plurality of heat dissipation channels; The top of heat dissipation channel and bottom are communicated with outside air respectively; Thereby the generation cross-ventilation is taken away the heat radiation of LED lamp, has prolonged the service life of LED lamp; Can effectively reduce LED lamp temperature inside; Good heat dissipation effect, installation, easy to maintenance suits to apply on a large scale.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Shown in Fig. 1-2, a kind of high heat dispersion LED lamp comprises shell 1; Fixedly lamp holder 3 of lamp holder deck 2 is passed through on the top of said shell 1; The inside of lamp holder 3 is provided with driving power 4, and the inside of shell 1 is provided with lamp bracket 5, and the outer surface of lamp bracket 5 is provided with a plurality of longitudinal bracing muscle 6; Form a plurality of heat dissipation channels between the inner surface of longitudinal bracing muscle 6 and shell 1; The bottom of lamp bracket 5 is provided with LED lamp plate 7, and LED lamp plate 7 is connected with driving power 4 through circuit, and the below of LED lamp plate 7 is provided with the diffusion shell 8 that is fixed on the shell 1.
The high heat dispersion LED lamp of the utility model is provided with diffusion retainer plate 9 between said shell 1 and the diffusion shell 8.
The high heat dispersion LED lamp of the utility model, the outer surface of said lamp holder 3 is provided with external screw thread.
The high heat dispersion LED modulated structure of the utility model is simple, according to stack effect, between the inner surface of longitudinal bracing muscle and shell, forms a plurality of heat dissipation channels; The top of heat dissipation channel and bottom are communicated with outside air respectively, thereby produce cross-ventilation, and the heat radiation of LED lamp is taken away; Prolong the service life of LED lamp, can effectively reduce LED lamp temperature inside, good heat dissipation effect; Installation, easy to maintenance suits to apply on a large scale.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
