In a preferred embodiment: one end of the reflecting cup is inserted into the light guide column.
In a preferred embodiment: a boss is arranged in the lampshade in a downward protruding mode along the axial direction; the lower surface of the boss is abutted against the other end of the reflection cup.
In a preferred embodiment: a fixing ring is arranged in the base in the axial direction of the base, and a through channel is arranged on the fixing ring along the axial direction of the base; the light source and the condenser lens are axially arranged in the fixed ring along the base; the through channel is communicated to the opening.
In a preferred embodiment: the upper surface of base is provided with the metal fin, the metal fin is provided with a plurality of louvres along circumference.
In a preferred embodiment: the opening is arranged on the metal heat radiating fin.
Compared with the prior art, the technical scheme of the utility model possess following beneficial effect:
1. the utility model provides a luminous desk lamp of base derives the light that the LED light source sent through the leaded light post from the base, and the reflection of the anti-light cup of rethread to the realization is hidden the base and is put the purpose in the base.
2. The utility model provides a luminous desk lamp of base has set up the metal heat piece on the base to set up the louvre on the metal heat piece, strengthened the heat dissipation of base, let the desk lamp use the temperature of back base for a long time also can not be very high, reduced the operating temperature of LED light source, increased the working life of LED light source.
Drawings
FIG. 1 is an exploded view of a desk lamp of the present invention;
fig. 2 is a light path diagram of the middle desk lamp of the present invention.
Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it should be noted that, unless explicitly stated or limited otherwise, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like are used in a broad sense, and for example, "connected," may be fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected through an intermediate medium, or connected between two elements.
Referring to fig. 1 and 2, the present embodiment provides a desk lamp with a light-emitting base, which includes a lamp shade 1, a base 3, a light guide column 2 and a light-reflecting cup 4; one end of the light guide column 2 is connected with the base 3, and the other end is provided with the reflecting cup 4; the lampshade 1 covers the reflecting cup 4;
the base 3 is provided with an opening 32 communicated with the light guide column 2, and the light source 31 and the condenser lens 33 are arranged in the base 3; the condensing lens 33 condenses the light emitted from the light source 31 into the opening 32, so that the light is guided by the light guide column 2, reflected by the reflective cup 4, and then diffused.
One end of the reflecting cup 4 is inserted into the light guide column 2. A boss 11 is arranged in the lampshade 1 in a downward protruding mode along the axial direction; the lower surface of the boss 11 is abutted against the other end of the reflection cup 4. This achieves a fixed mounting of the reflector cup 4.
In order to realize the installation of the LED light source 31 and the condenser lens 33, a fixing ring 34 is disposed in the base 3 in the axial direction of the base 3, and the fixing ring 34 is provided with a through channel along the axial direction of the base 3; the light source 31 and the condenser lens 33 are arranged in the fixing ring 34 along the axial direction of the base 3; the through passage communicates to the opening 32.
