Description

Background

In a conventional LED lamp, a lamp cover is mounted on an aluminum substrate above a wafer, and a heat sink is mounted on the aluminum substrate in a direction opposite to the wafer, that is, on the other surface of the aluminum substrate. When the LED chip emits light, the real effective illumination area is a part of area right below the light emitting direction, and obviously, the light on the side surface of the LED lamp is wasted. However, even though the light-transmitting flat mirror is used for corresponding improvement, for example, the light transmittance of the general light-transmitting flat mirror is often higher than 80%, but in order to weaken the glare effect of the light transmitted through the lampshade, a lampshade with lower light transmittance is required to be used, for example, the lampshade with light transmittance of about 70%, so that a part of the light intensity is offset by the lampshade to obtain the soft light effect. However, this causes a large loss of light to the LED chip.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in prior art fig. 1, an LED lamp includes: the LED chip comprises a substrate, a heat radiator (connected with the CD and positioned in a space surrounded by the CED) and an LED chip. Wherein the LED chip (position of O-spot) is placed on the substrate. And the LED chips are arranged in sequence along with the extending structure of the substrate (the position between the point C and the point D), so that the LED chips are arranged in a 180-degree plane, and the released light angle is 180 degrees at most. Obviously, the light emitting area of the LED chip is limited by the planar design of the LED lamp.

In addition, a lampshade (surface formed by points CFD) is mounted on the LED chip in fig. 1 and at a certain spatial distance from the substrate plane, the lampshade itself cannot completely improve the light emitting range, and the lampshade is often added, and because the distance from the lampshade to the LED chip is very short, the average light intensity irradiated on the lampshade is very high, and the lampshade with low light transmittance is necessary to obtain the soft light effect, so that the light loss of the LED chip is increased.

The first embodiment is as follows:

as shown in fig. 2 and 3, in order to solve the problems in the prior art shown in fig. 1, the present application provides a multi-surface LED lamp with a cup structure, comprising: the LED lamp comprises a base plate (GCDH structure) with an integrally formed lamp cup structure, at least two groups of LED lamp belts and a reflecting element for increasing reflecting efficiency, wherein the lamp cup structure is provided with a cup top opening (GH position) and a cup bottom base plate (C point-D point position), and the cross section of the cup bottom base plate is provided with a triangular or V-shaped bulge.

According to the above, the present application is specifically designed as follows:

the LED lamp belts are respectively arranged on two side surfaces (the position of the CF and the position of the FD) of the bulge, so that two light-emitting surfaces (namely a surface formed by the point CF and a surface formed by the point DF) are formed in the lamp cup structure, and the LED lamp belts are arranged on two sides of the bulge with a triangular or V-shaped cross section, namely the CF surface and the DF surface, so that the two light-emitting surfaces are formed. Based on this, the luminous angle that two plain noodles combined and constitute is then greater than 180 degrees, and the coverage area is bigger. And the problems that the LED lamp is only limited in the range of plane projection mapping light rays, glare is reduced and illumination efficiency is improved due to overlarge light loss are solved effectively.

And the number of the first and second groups,

the LED lamp strip is movably inserted into and pulled out of the bulges of the cup bottom substrate through sliding insertion structures arranged on two side surfaces (the position of CF and the position of FD) of the bulges, so that the LED lamp strip can be quickly disassembled and replaced at any time according to different requirements of users. For a LED strip, further comprising: the LED lamp comprises a plurality of LED light source parts and a lamp strip substrate, wherein the LED light source parts are preferably fixed on the lamp strip substrate in an array mode, and therefore the optimal irradiation and emission effects are achieved. Of course, the arrangement of the LED light source devices is not limited to this.

On both sides of the bump (position CF and position FD) there are also electrical inserts/electrical interfaces (not shown in fig. 2, 3), and the LED strip has also electrical interfaces/electrical inserts, through which it is electrically connected (points a and B) to both sides of the bump. For example, after the LED strip is mounted on two sides of the protrusion, the LED strip is plugged into the electrical interfaces on the two sides of the protrusion through the electrical plug-in components (power connection wires, ground wires, etc.) on the LED strip. Or,

and the two side surfaces of the protrusion and the LED lamp strip are respectively provided with an electrical contact, so that the LED lamp strip is electrically connected with the side surfaces through the contact between the electrical contacts. For example, electrical contacts are provided on the back of the LED strip, and electrical contacts are also provided on both sides of the bump. When the LED lamp strip is installed, the back surface of the LED lamp strip is attached to the two side surfaces of the protrusion, and the electrical contact of the back surface of the LED lamp strip corresponds to and contacts with the electrical contact of the side surfaces of the protrusion, so that electrical connection is automatically completed during installation.

In addition, the cup wall (CG position and HD position) of the lamp cup structure is provided with a movable fixing structure, so that the reflecting element can be movably inserted into the inner side of the cup wall through the movable fixing structure; the reflecting element is provided with a plane structure used for reflecting light rays emitted by the at least one group of LED lamp belts. The movable fixing structure comprises one or more of the following combinations: the clamping device comprises a sliding slot, a clamping piece and a clamping piece. Aiming at the difference of practical application, the reflecting element is connected with the cup wall of the lamp cup structure through a movable fixing structure (a sliding slot, a clamping piece, a buckling piece or the mutual combination of the sliding slot, the clamping piece and the buckling piece, and the like), so that the corresponding light effect processing can be realized through convenient connection.

For the arrangement of the light reflecting elements in this application, further explanation is:

through the arrangement of the reflecting element, a part of light emitted by the LED lamp strip is reflected by the reflecting element (the inner side of the CG position and the inner side of the HD position) and then emitted out from the cup top opening (the position of GH), and the other part of light emitted by the LED lamp strip is directly emitted out from the cup top opening (the position of GH). The lamp cup structure is adopted and the light-emitting element is combined to reflect and gather the light-emitting of the LED lamp strip to an effective irradiation position (under the lamp) as much as possible, so that the light-emitting angle is smaller, and the illumination efficiency of the LED in an effective irradiation area is enhanced. Therefore, the maximum lighting of the LED chip light source can be realized, and the lighting efficiency of the LED lamp with higher power can be obtained even if the LED lamp with lower relative power is used. I.e. the problem of light loss as presented in fig. 1 is avoided.

Example two:

with reference to fig. 2 and 3, the method further includes: and the lampshade is arranged at the cup top opening and suspended above the LED lamp strip (arranged at the position of GH), and the distance from the cup top opening to the bulge is more than a threshold.

The distance between the cup top opening GH and the F point is greater than a threshold, and the average light intensity irradiated on the lampshade is weaker due to the distance, so that the lampshade with higher light transmittance can not generate glare, and the light transmittance of the lampshade is improved, and the light loss of the LED chip lamp strip is effectively reduced.

Example three:

as shown in FIG. 2, the included angles formed by the cup walls of the lamp cup structure and the cup bottom substrate are all larger than 90 degrees, and the area of the cup top opening is larger than that of the cup bottom.

Or,

as shown in fig. 3, an included angle formed by one side cup wall of the lamp cup structure and the cup base substrate is greater than 90 degrees, an included angle formed by an opposite side cup wall of the one side cup wall and the cup base substrate is less than or equal to 90 degrees, and the one side cup wall and the opposite side cup wall are asymmetrically arranged in a batwing shape to form directional light emission (i.e., along the extending direction of CG and DH).

Through the two preferable settings of the included angle formed by the cup walls of the lamp cup structure and the cup bottom substrate, the directional light emission of the lamp can be controlled.

Example four:

with reference to fig. 2 and 3, the method further includes: and the heat dissipation section bar is arranged on one surface (connected with the CD and positioned in a space surrounded by the CED) of the cup bottom substrate far away from the LED lamp strip, and the shape of the heat dissipation section bar is adapted to the outline of the CED surface. In addition, the bulges are provided with hollow structures (C ' F ' D ') so as to form a ventilation and heat dissipation channel, so that the heat dissipation effect is not completely depended on the heat dissipation device per se by combining the heat dissipation mode of the prior art, and the bidirectional heat dissipation mode is realized.

The above description is only an example of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement or the like made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
