Abstract

The utility model discloses a horizontally-inserted light emitting diode (LED) lamp, which comprises a lamp cap (1), a radiating body (2) clamped with the lamp cap (1), a power module (3) arranged in a cavity inside the lamp cap (1) and the radiating body (2), a substrate (4) which is arranged on the radiating body (2) and is provided with LED light source bodies (41) and a light transmission cover (5). The LED lamp is characterized in that: the radiating body (2) is L-shaped; the substrate (4) and the light transmission cover (5) are arranged on the end face of an L-shaped notch of the radiating body (2); a plurality of radiating fins (21) which are uniformly distributed are arranged at the bottom of the radiating body (2); and light transmission particles (51) which are protruded inwards are uniformly distributed on the light transmission cover (5). Due to the design of the lamp, heat can be fully, effectively and quickly dissipated, interference among the LED light source bodies is reduced, long-time high-efficiency operation of the LED lamp is ensured, and the service life of the LED lamp is prolonged; in addition, light rays of the LED lamp are more uniform by the refraction of the light transmission particles which are protruded inwards on the light transmission cover, so that an illumination effect is improved.

Description

A kind of transverse-plug type LED lamp

Technical field

The utility model relates to a kind of LED lamp, particularly a kind of transverse-plug type LED lamp.

Background technology

Raising along with progress of science and technology and people's living standard; The LED lamp is more and more wider as a kind of its scope of application of energy-conservation environmental protection illumination; Transverse-plug type LED lamp generally all is forward because its good decoration effect is widely used in hotel, show room, shopping center, public place of entertainment but present LED lamp exists the light emission direction of some defectives: LED, owing to receive the restriction of LED lighting angle; Therefore present LED bulb is luminous to have a taper angle; Can not be the same with the fluorescent lamp bulb luminous to all directions like the conventional incandescent bulb, after using LED bulb replacement conventional bulb to put it into light fixture, because the difference of illumination mode can cause illumination effect and conventional bulb to differ greatly; Can not reach the illumination effect of Design of Luminaires, decorate properties is had a greatly reduced quality; In addition, present LED bulb is the requirement that reaches high brightness, and a fairly large number of LED need be set; Because the space is less in the bulb; In order to save the space, generally the LED staggered superposition is arranged that therefore each LED interferes with each other when luminous and can produce refraction and reflection; This can cause its light transmittance relatively poor again, and illumination effect is poor; The normal working temperature of LED light-emitting component generally is about 50 degree; In the course of the work, every again intensification 10 degree of LED, will shorten about 50% its service life; If do not solve LED light-emitting component heat dissipation problem, will have influence on the service life of LED bulb product greatly.

The utility model content

In order to overcome the deficiency of prior art, and optimize structure, the utility model provides a kind of radiating efficiency high, good illumination effect, transverse-plug type LED lamp attractive in fashion.

The utility model solves the technical scheme that its technical problem adopted:

A kind of transverse-plug type LED lamp comprises the radiator of lamp holder and lamp holder clamping; Be installed in the power module in lamp holder and the radiator internal cavities; Be installed in substrate that has the led light source body and diffuser on the radiator, described radiator is L-shaped, and substrate and diffuser are installed on the L shaped breach end face of radiator; The radiator bottom is provided with some equally distributed fin, is evenly distributed with to projecting inward light transmitting particles on the said diffuser.

As the improvement of technique scheme, described radiator set inside has wire guide.

Further, described radiator is connected through screw with substrate.

Further, described radiator edge and diffuser joint are provided with step.

The beneficial effect of the utility model is: the utility model is provided with large-area radiator, has not only improved the heat-sinking capability of transverse-plug type LED lamp, and is also more attractive in appearance in appearance; Radiator is provided with equally distributed fin in addition, has increased the contact area with air, can accelerate the heat conduction through open free convection, makes the heat of radiator be delivered in the air rapidly, thereby has played the effect of heat radiation; The led light source body is installed on the L shaped breach end face of radiator, and bigger distribution space can make the spacing between the led light source body strengthen relatively, and the interference between the lamp pearl emits beam also can reduce, and has so also improved its light transmittance and illumination effect to a certain extent; Drawing back of spacing reduced the concentrated accumulation of heat on the substrate in addition, and the heat of generation can be taken away through the radiator of direct contact, and the efficient of heat radiation is increased; When light when the diffuser, can increase the scattering refraction of light to projecting inward light transmitting particles on the diffuser, thereby make light more even, played the effect that improves its illuminating effect.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is the cutaway view of the utility model;

Fig. 2 is the front view of the utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2; A kind of transverse-plug type LED lamp of the utility model comprises the radiator 2 of lamp holder 1 and lamp holder 1 clamping; Be installed in the power module 3 of lamp holder 1 and radiator 2 internal cavities; Be installed in substrate that has led light source body 41 4 and diffuser 5 on the radiator 2, described radiator 2 is L-shaped, and substrate 4 is installed on the radiator 2 L shaped breach end faces with diffuser 5; The radiator bottom is provided with the equally distributed fin 21 of some semicircles, is evenly distributed with to projecting inward light transmitting particles 51 on the said diffuser 5.

Described radiator set inside has wire guide; Described radiator 2 is connected through screw 6 with substrate 4; Described radiator 2 edges and diffuser 5 joints are provided with step 23.

Heat radiation of this product and the principle of improving illuminating effect are: be provided with large-area radiator 2, not only improved the heat-sinking capability of transverse-plug type LED lamp when work, and also more attractive in appearance in appearance; Semicircle equally distributed fin 21 on the radiator 2 has in addition increased the contact area with air, can accelerate the heat conduction through open free convection, makes the heat of radiator 2 be delivered in the air rapidly, thereby has played the effect of heat radiation; Led light source body 41 is installed on the radiator 2 front end cross sections; Bigger distribution space can make the spacing between the led light source body 41 strengthen relatively; Interfere with each other also between the light that the lamp pearl sends and to reduce, so also improved its light transmittance and illumination effect to a certain extent; In addition spacing draw back the concentrated accumulation that has reduced heat on the substrate 4, the heat of generation can be taken away through the radiator 2 of direct contact, and the efficient of heat radiation is increased; When light when the diffuser 5, can increase the scattering refraction of light to projecting inward light transmitting particles 51 on the diffuser 5, thereby make light more even, played the effect that improves its illuminating effect.

Certainly, the utility model is except above-mentioned embodiment, and other equivalent technical solutions also should be within its protection domain.
