Abstract
The utility model relates to a light-emitting diode (LED) bulb. The LED bulb comprises a lamp base, a lamp shade, a circuit board, a controller and a plurality of LED lamp beads, wherein the lamp base is fixedly arranged on the top of the lamp shade. The inner surface of the lamp shade is coated with a light diffusing film. The circuit board, the controller and the LED lamp beads are arranged inside the lamp shade. The circuit board is electrically connected with the lamp base and coated with a fluorescent powder layer. The controller is installed on one side of the circuit board. The LED lamp beads are installed on the other side of the circuit board and arranged on the circuit board in a matrix shape mode. According to the LED bulb, the LED lamp beads are arranged in a large area, the LED lamp beads and the controller are arranged on different sides of the circuit board, and therefore heat dissipating effect is good and illumination intensity is large. Meanwhile, the lamp shade is coated with the light diffusing film, and therefore light generated by the bulb is not dazzling, and comfort degree is good.
Description
[technical field]
The utility model relates to a kind of bulb, is specifically related to a kind of LED bulb, belongs to field of illumination lamp technology.
[background technology]
In daily life, the majority of illumination light fixture is still continued to use traditional incandescent lamp.But along with the implementing plan of the superseded incandescent lamp of state compulsion, and the maturation gradually of LED technology, the LED bulb is replace incandescent gradually.
Yet influence main restricting factor that the LED bulb promotes at present by the following aspects: 1. heat dispersion is relatively poor, damages easily; 2. change frequently, cause the use cost height; 3. illumination is strong, and it is dizzy that the people is produced.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of structure improved LED bulb that has, to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model be to provide a kind of simple in structure, thermal diffusivity good and luminous not dazzling LED bulb.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of LED bulb, and it comprises lamp holder, lampshade, circuit board, controller and some LED lamp pearls; Wherein, described lamp holder is immobilizated in the top of lampshade; Inner surface in described lampshade is coated with one deck light-diffusing film; Described circuit board, controller and LED lamp pearl are contained in the lampshade; Described circuit board and lamp holder electrically connect, and are coated with the layer of fluorescent powder layer on it; Described controller is installed on a side of circuit board; Described LED lamp pearl is installed on the opposite side of circuit board; Described LED lamp pearl is rectangular and is arranged on the circuit board.
LED bulb of the present utility model further is set to: described lamp holder is screw socket.
LED bulb of the present utility model also is set to: described phosphor powder layer and LED lamp pearl are positioned at the homonymy of circuit board.
Compared with prior art, the utlity model has following beneficial effect: LED bulb of the present utility model is arranged LED lamp pearl by large tracts of land, and LED lamp pearl and controller are arranged at the not homonymy of circuit board, thereby makes good heat dissipation effect, and intensity of illumination is big; Simultaneously, by applying light-diffusing film at lampshade, the light that bulb is produced is not dazzling, makes comfort level good.
[description of drawings]
Fig. 1 is the schematic diagram of LED bulb of the present utility model.
[specific embodiment]
See also shown in the Figure of description 1, the utility model is a kind of LED bulb, and it is made up of several parts such as lamp holder 1, lampshade 2, circuit board 3, controller 4 and some LED lamp pearls 5.
Wherein, described lamp holder 1 is immobilizated in the top of lampshade 2, and it is traditional screw socket, thereby can be general with the incandescent lamp of transmission.
Inner surface in described lampshade 2 is coated with one deck light-diffusing film 6, and the light that bulb is produced is not dazzling, makes comfort level good.
Described circuit board 3, controller 4 and LED lamp pearl 5 are contained in the lampshade 2.Wherein, described circuit board 3 and lamp holder 1 electrically connects, by lamp holder 1 with power delivery to circuit board 3.Be coated with layer of fluorescent powder layer 7 on this circuit board 3, this phosphor powder layer 7 and LED lamp pearl 5 are positioned at the homonymy of circuit board 3, thereby can strengthen the luminous efficiency of this bulb.
Described controller 4 is installed on a side of circuit board 3, and it is used for the luminous of control LED lamp pearl 5.Described LED lamp pearl 5 is installed on the opposite side of circuit board 3.Because LED lamp pearl 5 and controller 4 are arranged at the not homonymy of circuit board 3, less being delivered on the controller 4 of heat that LED lamp pearl 5 produces, thus can not influence the operate as normal of controller 4.And described LED lamp pearl 5 is rectangular and is arranged on the circuit board 3, thereby increases the arrangement areas of LED lamp pearl 5, thereby makes good heat dissipation effect, and intensity of illumination is big.Further, described LED lamp pearl 5 is hemispherical structure, thereby makes light-emitting area big.
The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within make any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
