Abstract
The invention discloses a light emitting diode (LED) lamp which comprises a lamp cap, a bracket clamped with the lamp cap, a power supply arranged in the lamp cap and the bracket, a metal heat dissipation base connected with the bracket, and a substrate and a light transmission cover which are clamped on the metal heat dissipation base, wherein inward protruded light transmission particles are densely distributed on the light transmission cover; a bushing is arranged in the middle of the metal heat dissipation base; annularly distributed vertical cambered heat dissipation fins are arranged outside the bushing; and a heat dissipation hole is formed in the top of the bracket. Due to the refraction and scattering of a light ray on the round particles, the LED lamp improves a lighting effect; furthermore, heat dissipation is realized due to heat conduction and air convection, so that the service life of a lamp bulb is prolonged and the lighting effect of the LED lamp is improved.
Description
Technical field
The present invention relates to a kind of daily life tools, particularly a kind of LED lamp.
Background technology
Lighting bulb roughly comprises Halogen lamp LED; incandescent lamp; electricity-saving lamp and LED lamp; it is little that the LED lamp has been compared volume with other bulbs; life-span is long; no stroboscopic; the luminous efficiency advantages of higher; made great efforts to apply as energy-conserving product; but LED lamp pearl irradiating angle is little; non-uniform light; as normal lighting usually the dark space can appear; influenced lighting quality; single led in addition lamp pearl power is little; generally a plurality of LED lamp pearls are combined with series connection or mode in parallel as lighting bulb, along with increasing of LED lamp pearl, the increase of power; quantity of heat production rises thereupon; if it is bad that heat dissipation problem solves, heat concentrates in the small-sized chip, then can faster devices wear out; reduction of service life, even cause chip to burn.
Summary of the invention
In order to overcome the deficiencies in the prior art, and its structure is carried out certain optimization, the invention provides a kind of lighting quality height, the LED lamp of good heat dissipation effect.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of LED lamp, comprise lamp holder, support with the lamp holder clamping, be installed in the power supply of lamp holder and internal stent, the heat dissipation metal pedestal that is connected with support, and the substrate and the diffuser that are installed in the band led light source body on the heat dissipation metal pedestal, described diffuser is provided with inwardly protruded light transmitting particles.
In order to improve the radiating effect of technique scheme, be provided with sleeve pipe in the middle of the described heat dissipation metal pedestal, sleeve pipe is outside equipped with the vertical arc radiating fin of annular distribution.
Further, described top of the trellis is provided with louvre.
In order to increase aesthetic property, on the described substrate case ring is installed.
Connect reliably in order to make, described substrate is connected by screw with the heat dissipation metal pedestal.
The invention has the beneficial effects as follows: the inwardly protruded light transmitting particles on the diffuser, can increase the scattering and the refraction of light, make light more even, the bulb dark space of not throwing light on, thus reach the effect that improves illuminating effect; Radiator can be selected light weight for use, and good heat conductivity, commercial Application metal are widely carried out the heat conduction, add the heat radiation wing of annular array, have strengthened area of dissipation, help cross-ventilation and take away heat, have improved radiating efficiency; Substrate is directly installed on the heat dissipation metal pedestal, and the heat of generation can directly be taken away by the heat dissipation metal pedestal, has reduced the heat accumulation on the substrate; Prop up the louvre of top of the trellis and can further take away heat by convection current; Case ring makes LED lamp atmosphere more attractive in appearance.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a cutaway view of the present invention.
Fig. 2 is a front view of the present invention.
The specific embodiment
See figures.1.and.2, a kind of LED lamp of the present invention, comprise lamp holder 1, support 2 with lamp holder 1 clamping, be installed in the power supply 3 of lamp holder 1 and support 2 inside, with the aluminum metal cooling base 4 of support 2 clampings, and the substrate 5 and the diffuser 6 that are installed in the band led light source body 51 on the aluminum metal cooling base 4, described diffuser 6 is provided with inwardly protruded light transmitting particles 61.
Be provided with sleeve pipe 41 in the middle of the described aluminum metal cooling base 4, sleeve pipe 41 can be used to place lead and transmit heat, and sleeve pipe 41 is outside equipped with the vertical arc radiating fin 42 of annular distribution.
In order to improve its radiating effect, described support 2 tops are provided with louvre 21.
In order to increase aesthetic property, on the described substrate 5 case ring 7 is installed.
Connect reliably in order to make, described substrate 5 is connected by screw 8 with aluminum metal cooling base 4.
The present invention has utilized the ray refraction principle, when the light that sends when led light source body 51 passes diffuser 6 in bulb, because be provided with inwardly protruded light transmitting particles 61 in the diffuser 6, it is all inequality that light enters the incidence angle of diffuser 6, make the radiation direction that comes out from diffuser 6 have nothing in common with each other, reduce the luminous dark space of LED lamp thereby reached, improve the purpose of lighting quality; Present embodiment is dispelled the heat with the cross-ventilation dual mode by the heat conduction: the heat that led light source body 51 sends, a part is directly transferred on the aluminum heat dissipation metal pedestal 4 by substrate 5, radiating fin 42 on the aluminum heat dissipation metal pedestal 4 is vertical arc, arrange in the form of a ring, increased and air between contact area, help air and take away heat rapidly; Another part, the heat that bulb produces directly distributes in bulb inside, and hot-air rises and flows out from the louvre 21 at support 2 tops, and fresh air constantly sucks from the clamping slit between aluminum heat dissipation metal fin 42 and the diffuser 6, thereby reaches the heat radiation purpose.
Certainly, the present invention is except above-mentioned embodiment, and other equivalent technical solutions also should be within its protection domain.
