Description

Led lamp

Technical field

The present invention relates to a kind of lighting device, be meant a kind of led lamp especially.

Background technology

Light emitting diode has many characteristics such as environmental protection, power saving, life-span length and is applied to various fields widely as a kind of light emitting source efficiently.

Traditional led lamp comprises a tabular radiator and some light emitting diode module that is installed on this radiator one side.When light emitting diode was lighted, the light emitting diode module that is installed in radiator one side played illuminating effect.Because light emitting diode only is installed on radiator one side, the light that it sent can only go out from this side direction external radiation of radiator, and range of exposures is limited, illuminating effect is not good.

Summary of the invention

In view of this, but the led lamp that provides a kind of range of exposures bigger is provided.

A kind of led lamp, comprise a lamp bracket, be installed on a radiator of lamp bracket one side and be attached at some light emitting diode module on the described radiator, wherein said radiator has two inner concaves that are sticked for light emitting diode module, and described two inner concaves tilt and are provided with dorsad.

Compared with prior art, two inner concaves of led lamp of the present invention mutually dorsad and be obliquely installed and light emitting diode module is attached at two inner concaves, so the light of light emitting diode module emission can make the range of exposures of led lamp wider to the radiator ambient radiation.

With reference to the accompanying drawings, the invention will be further described in conjunction with specific embodiments.

The specific embodiment

As shown in Figures 1 and 2, led lamp of the present invention roughly is the books shape of opening, comprise a lamp bracket, be installed on lamp bracket one side second radiator 20, be installed on the lamp bracket opposite side two transparent light covers 40, be attached at some light emitting diode module 30 of radiator 20.

Please consult Fig. 3 and Fig. 4 simultaneously, this lamp bracket comprises two fixed mounts 10 that are arranged side by side and is positioned at and the housing 11 of fixed mount 10 1 sides.Each fixed mount 10 is roughly rectangular, is made up of the vertical two pairs of

side plates

12,13 that link to each other of head and the tail.Side plate 13 is the straight plate body of lengthwise and long than side plate 12.Each side plate 12 is curved.Two side plates 13 that two fixed mounts 10 are adjacent are parallel and interconnect and make two fixed mounts 10 form an integral body.Two side plates 12 of each fixed mount 10 with respect to interconnective side plate 13 both sides upwards, outwardly-bent extension and make two fixed mounts, the 10 common books shape symmetrical structures that open that form.Each radiator 20 and a light cover 40 cooperate with a fixed mount 10 and surround a host cavity 110.Described light emitting diode module 30 is contained in the host cavity 110.Housing 11 is positioned at host cavity 110 1 sides of two fixed mounts 10, and one drive circuit module (figure does not show) is contained in this housing 11, is used for electrically connecting with light-emitting diode module 30.This middle part, housing 11 outer ends is provided with a lamp socket 15 and is used for being connected with lamp stand (figure does not show).

Please consult Fig. 5 simultaneously, described each radiator 20 is made into integration by the good material of heat conductivility.This radiator 20 comprises an arc substrate 21 and a lengthwise installing plate 25 that extends to form from a side of substrate 21.Offer some installing holes (figure is mark not) on substrate 21 and the installing plate 25.Some screws (figure mark) pass the installing hole of installing plate 25 and cooperate with two fixed mounts, 10 interconnective side plates 13 and installing plate 25 is fixed on the fixed mount 10.Some screws (figure do not show) pass the installing hole on the substrate 21 and cooperate with

side plate

12,13 and then radiator 20 is fixed on the fixed mount 10.So, the second radiator 20 common symmetrical structures that form a books shape of opening, the substrate 21 of each radiator 20 constitutes an alar part of the books shape symmetrical structure that opens, and the substrate 21 of second radiator 20 deviates from mutually and makes progress, stretches out.

Each substrate 21 has the convex surface (figure is mark not) and an arc inner concave 211 relative with convex surface of an arc.Angle between the upper surface of the tangent line of this convex surface optional position and installation portion 25 is an acute angle.This inner concave 211 is for being formed by connecting along the equally distributed bus of an axis (figure does not show) (figure does not show).The bus of this inner concave 211 is parallel to each other.These inner concave 211 middle parts are divided into four lengthwise bar-shaped zones in equal size, and each bar-shaped zone is configured to a plane 2113 and is sticked on it for light emitting diode module 30.Each plane 2113 forms an acute angle with installing plate 25 lower surfaces, and these acute angles are along laterally outwards the successively decreasing gradually of substrate 21, and so, being attached at the light that the light emitting diode module 30 on the plane 2113 sent can be better to radiator 20 both sides radiation.Some fin 23 extend and vertically uniformly-spaced being provided with along substrate 21 vertically upward from the convex surface of substrate 21 and the upper surface of installing plate 25.Fin 23 laterally offers some ventilation slots (figure mark) along substrate 21.

Please consult Fig. 4 once more, each light emitting diode module 30 comprises circuit board 30 and some light emitting diodes 34 that evenly is fixed in circuit board 32 1 sides of a lengthwise rectangle.The another side of these circuit boards 32 fits on the plane 2113 of substrate 21 of radiator 20.These light emitting diodes 34 are positioned at along on the same straight line of circuit board 32 length directions extension, thereby its heat is conducted on the radiator 20 equably.

Described each lampshade 40 is a bending transparent sheet, comprises the transmittance section 41 of a lengthwise and is positioned at two installation portions 43 of 41 both sides, transmittance section.Be provided with some installing holes (figure is mark not) around each lampshade 40.Some screws (figure do not show) pass the installing hole of lampshade 40 and cooperate with the

side plate

12,13 of each fixed mount 10 and lampshade 40 is mounted on the fixed mount 10.

During use, light emitting diode 34 is switched on and is produced light, plays illuminating effect; Simultaneously, the heat that light emitting diode 34 produces is absorbed by the substrate 21 of radiator 20 and then conducts on the fin 23 of one side, goes thereby heat is dispersed in the external environment condition.

Among the present invention, second radiator 20 is the books shape of opening of symmetry, and the substrate 21 of second radiator 20 deviates from and toward the outer side mutually, so the light that light emitting diode module 30 is sent distributes to second radiator 20 both sides.Again because each radiator 20 substrates 21 concave surfaces 211 middle part is provided with the plane 2113 of four continuous outside settings, therefore, more traditional led lamp, the light that light emitting diode module 30 is sent can reach bigger scope.

Understandable, the second radiator 20 among the present invention can be integrally formed, thereby make second radiator 20 become a new radiator.
