Description

A kind of improvement of LED bulb structure

Technical field

The utility model belongs to a kind of LED bulb, refer to a kind of structural improvement especially the LED bulb.

Background technology

The structure great majority of existing LED bulb are that many led chip dense arrangement are arranged on the common horizontal installing plate, the brightness of its illumination relies on the quantity of led chip fully, its visual effect is bad, irradiating angle is little, can only be from the top down quadrature penetrate, can't reach omnibearing luminous effect.

In application number is 200910087625.5 patent, a kind of LED bulb has been proposed, comprise lamp holder, lamp socket and have LED and the light source module of circuit board, also comprise to improve the thermal column that the light source height reaches omnibearing luminous angle and can play thermolysis, lamp socket is a radiator, the one end connects lamp holder, the other end is provided with thermal column, fixed light source module on the free end of thermal column.Like this, thermal column promotes light source position, and light source is shifted out lamp socket, has improved the irradiating angle of light source, realized the illumination effects of approximate 360 degree of LED bulb, improved traditional LED and be installed in the deficiency that lamp socket substrate rear section is blocked by lamp socket near the LED light of horizontal direction.But, a little less than its brightness, make the whole non-uniform light of LED bulb on the one hand because the LED light emitting source is fixed on the end of thermal column, and stronger perpendicular to the regional luminance of light emitting source, other zone relies on the reverberation on thermal column surface to illuminate fully.On the other hand because thermal column has promoted the position of light source, and the luminous visual angle of LED is generally 110 and spends between 140 degree at present, when LED is shinny, can make a certain zone of the outside of LED bulb lampshade form the brightness blind area.

In another application number is 200920062393.3 patent, a kind of high-power LED bulb that has the leaded light post has been proposed again; comprise lamp holder; the cooling base of fixedlying connected with lamp holder; be arranged on the power-supply controller of electric in cooling base or the lamp holder; be fixed on the circuit board on the cooling base; on described circuit board, be provided with great power LED, on described cooling base, also be equipped with the cell-shell of a holding circuit plate and great power LED.Wherein, also comprise a leaded light post, an end of described leaded light post is provided with a cavity that is complementary with the light output end of great power LED, and the other end is provided with a circular arc concave surface, and the cavity of described leaded light post is nested with on the light output end of great power LED.Adopt the leaded light post can adjust the light irradiating angle of great power LED effectively, it is whole luminous and make high-power LED bulb reach effect of uniform light to reach 360 degree simultaneously.Yet because its led chip still is mounted on the circuit board on plane, around its light that sends reflexed to via the leaded light post, its brightness was not high, and the required part of this kind way is more, and the assembling more complicated can't be widely used.

The utility model content

At the deficiency that above technology exists, the utility model a kind of structural improvement is provided the LED bulb.

The technical scheme that the utility model is taked is as follows:

A kind of improvement of LED bulb structure comprises lamp holder, head capsule, lampshade and illuminator.Illuminator comprises circuit board and LED, constitutes variform stereochemical structure by circuit board, and LED is installed on the outer surface of this structure.

Stereochemical structure comprises cone, cylinder, cube, spheroid or irregular body.

Circuit board is made by metal substrate material or ceramic substrate material, and wherein, the metal substrate material comprises copper, aluminium, iron or stainless steel, and ceramic substrate material comprises aluminium oxide, Danization or aluminium nitride.

The beneficial effects of the utility model are: this bulb has stronger luminous flux and bigger irradiating angle, and the maximum illumination angle can reach 360 degree; Integral body is luminous and light is even, has eliminated the brightness blind area; Need not supporting body, easy to assembly, simple in structure.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

A kind of improvement of LED bulb structure comprises lamp holder 01, head capsule 02, lampshade 03, pedestal 05 and illuminator.Illuminator comprises circuit board 06 and LED 07, constitutes variform stereochemical structure by circuit board 06, and LED 07 is installed on the outer surface of this structure.Stereochemical structure comprises cone, cylinder, cube, spheroid or irregular body.Circuit board 06 is made by metal substrate material or ceramic substrate material, and wherein, the metal substrate material comprises copper, aluminium, iron or stainless steel, and ceramic substrate material comprises aluminium oxide, Danization or aluminium nitride.These materials can stretch and be crooked, make difform purpose to reach.

The improvement of LED bulb structure as shown in Figure 1, lamp holder 01 are connected an end of head capsule 02, draw two leads from the inside of lamp holder 01, are connected to the drive circuit that places in the head capsule 02.Pedestal 05 places the other end of head capsule 02, and the illuminator that is made of circuit board 06 places on the pedestal 05, is the inverted ladder-shaped body structure that the end increases gradually, and LED 07 just is installed on top and four sides.03 outside that covers on illuminator of lampshade, thus LED 07 and circuit board 06 are shielded.Owing on four sides under oblique, increased LED 07, increased the irradiating angle and the luminous flux of bulb.
