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, the lampshade with lower light transmittance is required to be used, for example, the lampshade with about 70% of light transmittance is frosted, so that a part of the light intensity is offset by the lampshade to obtain the soft light effect.

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 fig. 1, the LED lamp comprises a substrate, a heat sink (connected to the CD and located in the space surrounded by the CED), and an LED chip. The LED chip (location of point O) is placed on the substrate. And the arrangement of the LED chips is sequentially arranged along the extending structure of the substrate (the position between the point C and the point D). On the LED chip in fig. 1, a lampshade (surface formed by points CFD) is mounted at a certain spatial distance from the substrate plane, the lampshade itself cannot completely improve the light emitting range, and often, due to the addition of the lampshade, the average light intensity irradiated on the lampshade is very high due to the close distance from the lampshade to the LED chip, 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. In addition, the light-emitting angle of the LED chip is large, the light-emitting range can reach 0-180 degrees, for the LED lamp, 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.
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 an integrated LED lamp, including: a base plate (GCDH configured structure) having an integrally formed cup structure, at least one set of LED strips, a reflective element for increasing reflective efficiency, and wherein the cup structure has a cup top opening (GH position) and a cup bottom base plate (position between point C and point D), the at least one set of LED strips being mounted on the cup bottom base plate so as to be located within the cup structure. Preferably, the at least one set of LED strips comprises: the LED lamp comprises a plurality of LED light source parts and a lamp strip substrate, wherein the LED light source parts are fixed on the lamp strip substrate in an array mode.
With reference to fig. 2 and 3, the cup wall (CG position and HD position) of the lamp cup structure has a movable fixing structure, so that the light reflecting element can be movably inserted into the inner side of the cup wall through the movable fixing structure; wherein the reflecting element has a planar structure for reflecting light emitted by the at least one group of LED strips, and 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.
In addition, as the cup wall of the lamp cup structure is provided with the movable fixing structure, the reflecting element is movably inserted with the cup wall through the movable fixing structure; the reflecting elements with different requirements are installed on the wall of the cup, namely the reflecting elements with different requirements at different periods can be replaced at any time through the movable fixing structure and the movable insertion of the wall of the cup, so that different light refraction effects can be assisted.
Example two:
with reference to fig. 2 and 3 and the first embodiment, the cup bottom substrate has a sliding insertion structure, and the at least one group of LED strips is movably inserted into and pulled out of the cup bottom substrate through the sliding insertion structure. And the cup bottom substrate is also provided with an electrical plug-in/electrical interface, the at least one group of LED strips are also provided with an electrical interface/electrical plug-in, and the at least one group of LED strips are electrically connected with the cup bottom substrate through the electrical plug-in and the electrical interface. For example, the connection wires (power connection wires, ground wires, etc.) on the LED strip may be connected to the corresponding electrical components in the cup bottom substrate via the electrical plug/electrical interface on the cup bottom substrate.
Or the cup bottom substrate and the at least one group of LED lamp strips are respectively provided with an electrical contact, and the at least one group of LED lamp strips are electrically connected with the cup bottom substrate through the contact between the electrical contacts. For example, the electrical contact is arranged on the back of the LED lamp strip, when the LED lamp strip is installed, the back of the LED lamp strip is attached to the cup bottom substrate, and the electrical contact on the back of the LED lamp strip happens to correspond to and contact with the electrical contact at the corresponding position on the cup bottom substrate, so that electrical connection is automatically completed during installation.
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. By the arrangement mode that the area of the opening at the top of the cup is larger than the area of the bottom of the cup, the whole lamp cup structure is similar to the ladder funnel shape shown in fig. 2, the light emitting of the lamp can be effectively controlled, the emergent light of the lamp is effectively gathered under the lamp, and the problems of weak light emitting effect and the like caused by the reduction of the light emitting angle and the like are solved.
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).
For the included angle setting of cup wall and bottom of cup base plate, can carry out corresponding processing when integrated into one piece according to different conditions to form the base plate that has multiple included angle. The present application is not so limited.
Example four:
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 O point is larger than a threshold, the average light intensity irradiated on the lampshade is weaker due to the distance, the lampshade with higher light transmittance can be used, glare cannot be generated, and the light transmittance of the lampshade is improved, so that the light loss of the LED chip lamp strip is effectively reduced.
With reference to fig. 2 and 3, the LED lamp further includes a heat dissipation profile mounted on a side of the substrate (connected to the CD and located in the space surrounded by the CED) away from the at least one group of LED strips. As the heat dissipation profile, a heat sink, and the like may be used, but the present application is not limited thereto.
