Abstract

The utility model discloses an LED energy saving lamp with a good heat radiation effect, which comprises a lamp socket, an LED light source, a driver, a radiator and a light penetration cover. The radiator is equipped with radiating fins. Gaps are arranged between adjacent radiating fins. The lamp socket is equipped with air vents corresponding to the gaps and the air vents are docked with the gaps. A fan is arranged inside the lamp socket. The radiator is arranged between the lamp socket and the light penetration cover. The radiating fins and the gaps of the radiator are exposed to the outside. The transverse sections of the radiating fins are Y-shaped. The bifurcated ends of the radiating fins are arranged toward the outer side of the radiator. According to the utility model, the radiating fins are arranged annularly and the front ends of the radiating fins adopt a Y-shaped bifurcated structure. Therefore, the contact area of the radiator with the outside is increased and the heat radiation effect is improved. Meanwhile, the fan is arranged inside the lamp socket. When the fan is in work, air is blown toward the radiator through the air vents by the fan. Heat generated during the working of an LED is quickly transmitted to the air through the radiator, so that the temperature of the working environment of the LED is lowered. Therefore, the service life and the energy saving effect of the LED are improved.

Description

A kind of LED electricity-saving lamp of good heat dissipation effect

Technical field

The utility model relates to the lighting product technical field, is specifically related to a kind of LED electricity-saving lamp.

Background technology

Luminous efficiency height, power consumption are few because led light source has, long service life, security reliability are strong, meet characteristic such as energy conservation and environment protection it is believed that the 4th generation new light sources.At present, LED is energy-conservation to have begun to use to marketing, and existing many cities are applied to the led light source lighting engineering in the city illumination environmental construction, and has produced good effect.As everyone knows, the topmost shortcoming of LED lamp is that caloric value is big, and because the space of installation led light source is less; Therefore; If can not solve the heat dissipation problem of LED well, then can influence the work of LED, and then cause the LED lamp comparatively fast to wear out, damage; Reduce the service life of LED, do not reach energy-conservation effect.At present; Usually adopt radiator to solve the heat dissipation problem of LED lamp; Promptly be installed in the radiator of aluminum alloy material, the fin of multi-disc independence sheet is set on the radiator, belong to passive radiating mode to driver; Its shortcoming is a radiating effect or not ideal enough, to the energy-saving effect of LED lamp and harmful effect is all arranged service life.

The utility model content

The utility model is to the defective of prior art, and a kind of LED electricity-saving lamp that solves defectives such as bad, very fast aging, service life of the existing heat radiation of existing LED light fixture and energy-saving effect be undesirable is provided.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of LED electricity-saving lamp of good heat dissipation effect comprises lamp socket, led light source, driver, radiator and diffuser; Led light source connects with driver and is installed on the lamp socket; Driver is connected with radiator, and radiator is connected with lamp socket, and diffuser is installed on the radiator; It is characterized in that: be cavity in the middle of the radiator; Be radiating fin all around, leave the space between the adjacent radiating fin, radiating fin is looped around around the cavity; The lamp socket center is a cavity, and this cavity is corresponding with the cavity of radiator, is provided with and the corresponding air vent in the space of radiator around the cavity, and the openend of air vent is positioned at lamp socket and the contacted side surface of radiator, and air vent docks with the space of radiator; Fan is installed in the lamp socket, and when using lamp, fan initiatively blows to radiator with the hot-air in the lamp, and then distributes to the external world through radiator, so can quicken the lamp inner air flow, improves radiating effect; Radiator is installed between lamp socket and the diffuser, and the radiating fin and the space of radiator are exposed.

Preferably, said radiator is cylindrical, and radiating fin is disposed radially, and the lateral cross section of radiating fin is " Y " font, and the jag end of radiating fin is towards the outside of radiator, and the tail end of all radiating fins links together and is looped around around the cavity.

Preferably, the quantity of air vent and shape are all corresponding with the space of radiator, and each air vent docks with space, a place.

Preferably, lamp socket is provided with the inlet scoop, and the inlet scoop is connected with air vent.

Preferably, the equal circular array of said radiating fin and air vent.

The beneficial effect of the utility model is: radiating fin is provided with ringwise, and exposes outside lamp, and the front end of radiating fin is " Y " shape bifurcation structure; So more increased radiator and extraneous contact area, improved the radiating effect of radiator, in addition owing in the lamp socket fan is installed; When fan work; Can be through air vent to radiator one cross air blasting, through radiator LED work is produced heat and be delivered to rapidly in the middle of the air, thereby make the work calories of LED can not accumulate in the diffuser; Reduce the operating ambient temperature of LED, can prolong service life and the energy-saving effect of LED.
