The beneficial effects of the utility model: a kind of miniature LED bulb is provided, due to the LED module group substrates that adopts column, side and end face at the LED module group substrates is provided with LED chip simultaneously, therefore this miniature LED bulb can be to the comprehensive emission of light of surrounding, illumination effect is good, the utility model adopts the end face at module group substrates to be provided with the power supply connecting hole be connected with power supply module simultaneously, and then give each LED chip power supply by the power supply connecting hole, thereby the complexity of having avoided each LED chip to bring from the power supply module power taking separately wiring, effectively simplified fitting structure, make fitting structure simpler, be convenient to small size production.
The accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any restriction of the present utility model, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain according to the following drawings other accompanying drawing.
The decomposing schematic representation of the embodiment that Fig. 1 is a kind of miniature LED bulb of the utility model.
The specific embodiment
With the following Examples the utility model is further described.
The specific embodiment of a kind of miniature LED bulb of the utility model, as shown in Figure 1, comprise: be provided with the base 1 that connects pin 11, described base 1 is provided with and the power supply module 3 that is connected pin 11 connections, this miniature LED bulb also comprises radiator 2, described base 1 is sheathed on an end of radiator 2, the other end of described radiator 2 is fixedly installed heating column 4, described heating column 4 is arranged with the LED module group substrates 5 of column, the side of described LED module group substrates 5 and end face are provided with LED chip 51, the end face of described LED module group substrates 5 is provided with the power supply connecting hole, described LED chip 51 is by the power taking of power supply connecting hole, described power supply connecting hole is connected with connecting line 7, described connecting line 7 runs through heating column 4 and is connected with radiator 2 and with power supply module 3.
Due to the LED module group substrates 5 that adopts column, side and end face at LED module group substrates 5 is provided with LED chip 51 simultaneously, therefore this miniature LED bulb can be to the comprehensive emission of light of surrounding, illumination effect is good, the utility model adopts the end face at module group substrates to be provided with the power supply connecting hole be connected with power supply module 3 simultaneously, and then give each LED chip 51 power supplies by the power supply connecting hole, thereby the complexity wiring of having avoided each LED chip 51 to bring from power supply module 3 power takings separately, effectively simplified fitting structure, make fitting structure simpler, be convenient to small size production.
Be provided with radiating fin 41 on described heating column 4.Due in undersized LED light fixture, LED chip 51 is comparatively intensive, radiating requirements is larger, undersized radiator 2 heat-sinking capabilities are limited simultaneously, therefore rely on heating column 4 by heat conduct to radiator 2 more outwards heat radiation be to be difficult to meet the radiating requirements of LED chip 51, so increase radiating fin 41 on heating column 4, increase the heat-sinking capability of heating column 4.
The miniature LED lamp of the present embodiment also comprises transparent housing 6, and described transparent housing 6 is fixedly connected with radiator 2.Be provided with internal thread 62 on described transparent housing 6, be provided with external screw thread 21 on radiator 2, described transparent housing 6 and radiator 2 are threaded connection.Transparent housing 6 not only can be protected the internal structure of light fixture, also can play certain refraction/reflection effect to light, makes distribution of light more even simultaneously.Transparent housing 6 adopts and is threaded with radiator 2 simultaneously, and this is not only easy to assembly, and is convenient to field-strip when breaking down.
