The specific embodiment

Shown in Fig. 1 to 7, a kind of high-efficiency heat radiating LED bulb described in the utility model, comprise lamp holder 1, lampshade 2 and be located at the interior lamppost 3 of lampshade, described lamppost 3 middle parts are provided with a radiator structure 4 with at least one stovepipe 41, lampshade 2 is run through on these stovepipe 41 tops, and the bottom communicates with the radiating groove 5 of being located at lampshade 2 bottoms.

Particularly: above-mentioned lampshade 2 is made up of upper lamp shade 21 and lower lamp shade 22, is provided with a sealing installing plate 6 between the upper and lower lampshade (21,22), and lower lamp shade 22 bottoms and lamp holder 1 fixing (as shown in Figure 6), upper lamp shade 21 adopt with lower lamp shade 22 and be threaded; Described sealing installing plate 6 middle parts are provided with stovepipe bottom installing port 61 (shown in Fig. 1 and 7), and described upper lamp shade 21 is provided with stovepipe top installing port 211 (as Fig. 5).Above-mentioned lower lamp shade 22 is provided with radiating groove 5 (as shown in Figure 4), and heat radiation poor 5 and stovepipe 41 are formed the heat dissipation channel of convection current.

Above-mentioned lamppost 3 then is located in the confined space that sealing installing plate 6, radiator structure 4 and upper lamp shade 2 surround, and it adopts the insulated conductor 7 that passes sealing installing plate 6 to be connected with lamp holder 1.Above-mentioned insulated conductor 7 is connected with lamp holder 1 by the lead perforation on the sealing installing plate 6 62.Waterproofing protection for lamppost 3; adopt fluid sealant to be sealing adhesive between above-mentioned insulated conductor 7 and the lead perforation 62; and be equipped with sealing ring 8 (as shown in Figure 1) between above-mentioned stovepipe top installing port 211, stovepipe bottom installing port 61 and the stovepipe 41 and between sealing installing plate 6 and the upper and lower lampshade (21,22).

Further, comprise the lamp pearl electron plate 32 that vertically is arranged on radiator structure 4 peripheries, be installed in the some LED lamp pearls 31 on the lamp pearl electron plate 31 and be horizontally installed on the power supply electronic plate 33 of lamp pearl electron plate 32 belows that as the above-mentioned lamppost 3 of Fig. 1 power supply electronic plate 33 is connected with lamp pearl electron plate 32 and insulated conductor electrical 7.Angle α between above-mentioned lamp pearl electron plate 32 and the bulb central axis is an acute angle, and further preferred, above-mentioned angle α is 0 °～45 °, and above-mentioned angle α the best is 15 °.The purpose of above-mentioned setting is for bulb bigger illumination range to be arranged, and existing general its lamppost of LED bulb all is columniform, be that its lamp pearl electron plate is parallel with the bulb central axis, again because the lighting angle of LED lamp pearl has scope, generally be no more than 125 °, therefore the illumination deficiency can appear in existing LED bulb top, the illumination dark space occurs.The utility model adopts up big and down small bench-type lamppost design can make LED bulb top can send stronger light equally, and illumination range is bigger, efficiently solves the problem that the not enough illumination of illumination dark space appears in existing LED bulb top.

Below come the utility model is further described by concrete radiating principle:

As shown in Figure 2, when the utility model bulb is upwards placed use, the heat transferred radiator structure that produces by the work of LED lamp pearl, according to aerodynamics, radiator structure chimney inner air tube is heated the back and rises, hot-air is got rid of by the outlet of stovepipe top, negative pressure occur in the lampshade this moment, extraneous cold air sucks additional by the radiating groove of lampshade bottom, cold air absorbs when the stovepipe to be passed to by LED lamp pearl and becomes hot-air behind the heat of radiator structure and continue to rise, continuous circulation by such air-flow, the heat that LED lamp pearl is sent is taken away continuously, thereby can reach high efficiency and heat radiation, and preventing that the light decay problem from appearring in LED lamp pearl, can increase the service life simultaneously.In like manner, as shown in Figure 3, when the utility model bulb is placed use downwards, the heat transferred radiator structure that produces by the work of LED lamp pearl, according to aerodynamics, radiator structure chimney inner air tube is heated the back and rises, hot-air is discharged by the stovepipe lower part outlet, after radiating groove discharge, negative pressure occur in the lampshade this moment, and extraneous cold air is sucked by the stovepipe upper port and replenishes, and cold air absorbs during through stovepipe to be passed to by LED lamp pearl and becomes hot-air behind the heat of radiator structure and continue to rise, by the continuous circulation of such air-flow, the heat that LED lamp pearl is sent is taken away continuously.

The utility model is simple in structure, and it is provided with the radiator structure of band stovepipe in lamppost, can take away the heat in the lamppost rapidly, and high efficiency and heat radiation the light decay problem occurs to prevent LED lamp pearl, can increase the service life simultaneously.The utility model adopts upper and lower lampshade separately to be screwed into one lampshade simultaneously; be convenient to make and produce; reduce manufacturing cost; accomplish to take into full account the waterproofing protection problem of lamppost simultaneously; the sealing installing plate is set between last lower lamp shade; and increase sealing ring at each interface, lamppost is in the space of complete water-tight.More have, the utility model adopts up big and down small bench-type lamppost design can make LED bulb top can send stronger light equally, and illumination range is bigger, efficiently solves the problem that the not enough illumination of illumination dark space appears in existing LED bulb top.

Should be noted that, below only be to have described preferred forms of the present utility model, the mode that other any all forms is close, adopt form slightly to change, but practical structures all belongs to the same product of the utility model actual content and invades patent right of the present utility model.
