Description

The LED bulb
Technical field:
The present invention relates to lighting technical field, specifically is a kind of LED bulb of 360 ° of full firing angles.
Background technology:
The LED bulb has replaced traditional osram lamp gradually at present, becomes the main flow on the market.The light source of traditional osram lamp is 360 ° of projections, and owing to the LED lamp plate in the LED bulb comprises substrate and is located at the LED on the substrate, and because substrate is opaque, therefore, present LED bulb can only be done unidirectional projection light, and illumination zone is limited.
Therefore; Occur a kind of LED bulb of 360 ° of full firing angles at present, it comprises the Transparent lamp shade of a sealing, is provided with a radiator in the lampshade; Radiator is fixed through the gripper shoe that is arranged in the lampshade, at the upper surface and the lower surface of radiator the LED lamp plate is housed all.The LED lamp plate of upper surface sends projection light up like this, and the LED lamp plate of lower surface sends projection light down, can accomplish 360 ° of full firing angles basically.Not enough below but the LED bulb of this structure also has:
The first, because radiator is to be contained in the Transparent lamp shade of sealing, the extraneous air of radiator and bulb completely cuts off, so radiating effect is poor; The power increase of bulb is difficulty relatively; And because radiator is to fix through the gripper shoe in the lampshade, intensity is lower, the big words that radiator is done; Connect built on the sand the also corresponding difficulty of making high-power bulb that increased.
Though second gripper shoe and radiator are arranged is that the space in the Transparent lamp shade is divided into up and down two parts; But up and down between two parts at a distance from light; That is to say that the LED lamp plate of radiator upper surface and the LED lamp plate of lower surface need be colors of the same race, color is single; Can only do the usefulness of illumination, decorative effect is relatively poor.
Summary of the invention:
Main purpose of the present invention is, overcomes existing technological deficiency, and a kind of good heat dissipation effect is provided, and intensity is high, the LED bulb of good decorating effect.
Technical scheme provided by the invention is: the present invention provides a kind of LED bulb; It comprises jockey, radiator and transparent upper lamp shade and lower lamp shade, and said upper lamp shade is connected through heat sink with lower lamp shade, and the upper surface of said heat sink is provided with a LED lamp plate; The lower surface of said heat sink is provided with the 2nd LED lamp plate; Said radiator is located between jockey and the upper lamp shade, and the part of radiator is outside at upper lamp shade, and another part of radiator is inner at upper lamp shade; And be connected with a LED lamp plate, said radiator middle part also has the cavity that is used to place driving power.
Said jockey comprises insulation screw socket that is positioned at the jockey side and the metal screw socket that is positioned at the bulb top.
A said LED lamp plate comprises first substrate and is located at the LED on first substrate that said the 2nd LED lamp plate comprises second substrate and is located at the 2nd LED on second substrate.
Adopt said structure, the present invention has the following advantages:
The first, the present invention adopts the form that upper and lower lampshade separately links together through heat sink then; The thickness of heat sink just can be regulated as required like this; If the power of LED bulb is bigger; Just can correspondingly increase the thickness of heat sink, improve so that do the feasibility of high-power LED bulb.And owing to also be provided with radiator in the LED bulb of the present invention, radiator both was connected with the inner LED lamp plate of bulb, contacted with the bulb air outside again; Radiating effect is better; And radiator also played the effect that connects the inner LED lamp plate of fixing bulb, connects firm firmly, the intensity height.More improved the feasibility of doing high-power LED bulb.
The second, the present invention has adopted LED lamp plate and heat sink that upper lamp shade in the bulb and lower lamp shade are separated; The bulb volume inside is divided into upper and lower two parts, because the substrate in the LED lamp plate is opaque, so the upper and lower two parts in the bulb are at a distance from light; So just can make the first LED lamp plate and the 2nd LED lamp plate make different colours; Perhaps make upper lamp shade and lower lamp shade make different colours, good decorating effect can play the effect of ornament lamp.
As improvement, said radiator also is provided with the 3rd LED lamp plate on the inner outer surface of upper lamp shade.On the inner radiator outer surface of upper lamp shade, be provided with the lamp source that the 3rd LED lamp plate can make to be had on the bulb towards lateral emitting, increase luminous angle and intensity.
As further improvement, the side of said heat sink also has radiating groove.On heat sink, slot, help to increase area of dissipation, strengthen radiating effect.
