Abstract

The utility model discloses an LED bulb, comprising a copper lamp head and a bulb shell fixedly connected on the copper lamp head, wherein the bulb shell is connected with a light-transmitting lamp cover; the inner part of the lamp shell is provided with a radiating device which is internally placed with a power supply plastic shell; the power supply plastic shell is internally placed with a power supply; one end of the power supply is electrically connected with the copper lamp head, and the other end thereof is electrically connected with a lamp panel which is an LED template and is formed by adopting an LED chip to be directly packaged on an aluminium base plate; the lamp panel is provided with a light-gathering lens for gathering light; the lamp panel is plated with a fluorescent powder material; and the light-transmitting lamp cover is plated with the fluorescent powder material. The LED bulb has very simple structural and material requirements, has high radiating efficiency, high working reliability and easy large-scale production, and can replace the existing common bulb and the energy-saving bulb.

Description

The LED bulb
Technical field
The utility model relates to a LED bulb, and especially a kind of common electrical bulb that can replace is used to throw light on, is fit to the LED bulb that various occasions such as family are used.
Background technology
LED (light emitting diode) has long, advantage such as light efficiency is high, radiationless, shock resistance and low-power consumption of life-span, belong to energy-conservation environmental protection illumination, therefore all used LED in the decorative lightings such as present most indicator lamp and neon light, and national governments all in encourage growth LED technology with energy savings, if adopt led light source to throw light on, can save a large amount of electric energy.But existing LED bulb uses high-powered LED lamp more, simultaneously prior art is difficult to solve the heat dissipation problem of high-power LED bulb, and wiring board also is the common LED wiring board, because that use is single LED, make the brightness of LED wafer can't reach best effects, thereby influenced the brightness of bulb.
Current society, when paying attention to energy-conserving and environment-protective, to the brightness of lighting with very high requirement is also all arranged service life, traditional energy-saving bulb can not reach the requirement of environmental protection and energy saving, the existing high-power LED bulb in market, because heat dissipation problem is difficult to solve, serious its service life, the low power LED bulb of some of Chu Xianing recently of restricting, because what use is common LED lamp and wiring board, its brightness can not reach perfect condition.These all affect the extensive use of LED bulb.
The utility model content
For overcoming deficiency of the prior art, the purpose of this utility model is to provide a kind of LED bulb, and it has solved, and heat radiation is difficult, the low problem of brightness, has the life-span farm labourer and makes the good characteristics of performance.
In order to solve the problems of the technologies described above the realization above-mentioned purpose, the utility model has been taked following technical scheme:
A kind of LED bulb comprises a brass lamp holder and the bulb shell that is fixedly connected on the brass lamp holder, and described bulb shell connects a printing opacity light cover; Be provided with a heat abstractor in the inside of described bulb shell, place the power supply plastic housing in the described heat abstractor, be placed with power supply in the described power supply plastic housing, described power supply one end is electrically connected brass lamp holder, and the described power supply other end is electrically connected a lamp plate.
Further, described lamp plate is a LED template, adopts the LED wafer directly to be encapsulated on the aluminium base and constitutes.
Further, described lamp plate is provided with a light-collecting lens that is used for optically focused.
Preferably, be coated with phosphor material powder on the described lamp plate.
Preferably, be coated with phosphor material powder on the described printing opacity light cover.
Compared with prior art, the utlity model has following advantage:
Lamp plate described in the utility model adopts the LED wafer directly to be encapsulated in the modularized design of aluminium base, make the light-emitting area of wafer bigger, more even, and the large-area fluorescent material of smearing on described lamp plate, fluorescent material can more effectively be excited by the LED wafer, thereby improve fluorescence efficiency effectively, reduce the light decay speed of wafer greatly; Adopt modularized design in addition, help the wafer heat radiation, thus the service life of improving bulb.Described light-collecting lens can require to assemble light according to different optically focused angles, thereby the brightness of bulb is strengthened greatly.Described printing opacity light cover since adopt phosphor material powder make the brightness of bulb stronger, luminous more even, simultaneously can make different colour temperatures according to requirement of client, integral body is more elegant in appearance.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model one example structure schematic diagram;
Fig. 2 is that the lamp plate modular design of this practical embodiment structure is shown the structure intention.
Number in the figure explanation: 1. brass lamp holder, 2. bulb shell, 3. power supply, 4. power supply plastic housing, 5. heat abstractor, 6. lamp plate, 7. light-collecting lens, 8. printing opacity light cover, 9. phosphor material powder, 10.LED wafer.
The specific embodiment
Referring to Fig. 1, shown in Figure 2, LED bulb of the present utility model comprises a brass lamp holder 1 and the bulb shell 2 that is fixedly connected on the brass lamp holder 1, and described bulb shell 2 connects a printing opacity light cover 8; Be provided with a heat abstractor 5 in the inside of bulb shell 2, place power supply plastic housing 4 in the heat abstractor 5, be placed with power supply 3 in the power supply plastic housing 4, power supply 3 one ends are electrically connected brass lamp holder 1, and power supply 3 other ends are electrically connected a lamp plate 6.
Further, lamp plate 6 is a LED template, adopts LED wafer 10 directly to be encapsulated on the aluminium base and constitutes.
Further, lamp plate 6 is provided with a light-collecting lens 7 that is used for optically focused.
Preferably, be coated with phosphor material powder 9 on the lamp plate 6.
Preferably, be coated with phosphor material powder 9 on the printing opacity light cover 8.
Obviously; the design that lamp plate 6 shown in above-mentioned Fig. 2 adopts LED wafer 10 directly to be encapsulated on the aluminium base; just to of the present utility model specifying and and unrestricted; can reach will be understood that still within protection domain of the present utility model of requirement of general lighting light source; the utility model structure and material requires all very simple; be easy to large-scale production, can replace present common bulb and energy-saving bulb.
