Description

A kind of desk lamp with hidden side inclined plane of light source

technical field

The utility model relates to a desk lamp, in particular to a desk lamp with a hidden side inclined surface of a light source.

Background technique

Desk lamp is the lamps and lanterns that family always has, and is used for lighting when people work or study. Ordinary table lamps are composed of a lamp holder, a lamp holder and a lamp frame. Usually, the lamp holder structure of an ordinary table lamp is as follows: including a lamp holder shell, and a light source (LED lamp bead) is arranged inside the lamp holder shell, and the light emitted by the light source is directly emitted to the Where lighting is required, in the above structure, people can directly see the light source through the light-transmitting plate, so its aesthetics is not high enough, and the direct illumination of the light source has the advantages of high spot area brightness, concentrated light, uneven light, uncomfortable reading and eye damage , so it is necessary to improve the above structure.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a desk lamp with a hidden side inclined surface of the light source which is beautiful and has good light effect.

The technical scheme that the utility model solves its technical problem adopts is:

A desk lamp with a hidden side inclined surface of a light source, comprising a lamp base housing, a light outlet is arranged on the lamp base housing, a light-transmitting plate is arranged at the light outlet, a circuit board is arranged inside the lamp base housing, and LED lamp beads are arranged on the circuit board. The feature is that a reflector with specular high-gloss aluminum on the inner surface is provided in the lamp holder housing, and the light emitted by the LED lamp beads is diffusely reflected by the reflector and then emitted to the area to be illuminated through the light-transmitting plate.

The reflector includes a flat reflective surface, one side of the flat surface is smoothly connected with an arc-shaped reflective surface, and the other side of the flat surface is provided with a mounting groove, the circuit board is clamped in the mounting groove, and the LED lamp beads emit The light is incident on the curved reflective surface and the flat reflective surface.

The circuit board is arranged obliquely, and the angle between the surface on which the LED lamp beads are installed and the flat reflective surface is an acute angle.

Several heat sinks are arranged on the reflector.

Both ends of the reflector are provided with end plates, and the end plates are locked in the lamp cap shell by screws, and the reflector is pressed tightly in the lamp cap shell of the reflector through the end plates.

Sides are provided on the edge of the arc-shaped reflective surface, and a support plate is provided inside the lamp holder housing, and the side is supported and positioned by the support plate.

The beneficial effects of the utility model are: the structure includes a lamp holder housing, a light outlet is provided on the lamp holder housing, a light-transmitting plate is provided at the light outlet, a circuit board is arranged inside the lamp holder housing, and LED lamp beads are arranged on the circuit board. A reflector is provided inside the lamp holder housing, and the light emitted by the LED lamp bead is reflected by the reflector and then emitted through the light-transmitting plate. Through the setting of the reflector, the light emitted by the LED lamp bead can be reflected from the reflector. The light-transmitting plate shoots out, thus avoiding the direct exposure of the LED lamp beads on the light-transmitting plate and affecting the overall appearance of the lamp body, and after being reflected by the reflector, the light irradiation range can be expanded, and the light brightness and distribution can be uniform, so as to achieve high illuminance. The soft light effect realizes the purpose of comfortable reading and protects the eyes, which improves the quality of the product.

Description of drawings

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

Fig. 1 is a perspective view of the utility model;

Fig. 2 is the internal structure view of the utility model;

Fig. 3 is a structural view of the reflector;

Figure 4 is a side view of the reflector.

Detailed ways

Referring to Fig. 1 to Fig. 4, the utility model discloses a desk lamp with a side inclined surface of the light source, which comprises a long semicircular tubular lamp cap shell 1, one side of the lamp cap shell 1 is open, and it is closed by a panel 2, which is provided with a light outlet , a light-transmitting plate 3 is provided at the light outlet, and a reflector 4 with specular high-gloss aluminum on the inner surface is provided in the lamp holder housing 1. The reflector 4 is facing the light-transmitting plate 3, and the light emitted by the LED lamp beads passes through the reflector. 4 After diffuse reflection, it is emitted to the area that needs to be illuminated through the light-transmitting plate 3 .

As shown in the figure, the reflective surface of the reflector 4 includes a flat reflective surface 5, one side of the flat surface is smoothly connected with an arc-shaped reflective surface 6, and the other side of the flat surface is provided with a mounting groove 7, and the circuit board is clamped on the In the installation groove 7, the installation groove 7 has a notch facing the inner reflective surface of the reflector 4, and the LED lamp beads face the notch, so the light emitted by the LED lamp beads can be emitted through the flat reflective surface 5 and the curved reflective surface 6 , and the curved reflective surface 6 can disperse the light evenly and expand the illumination range, while the flat reflective surface 5 can directly reflect part of the light, which strengthens the illumination brightness of the central part. As a further optimal design of the above structure, the circuit board Inclined setting, of course, the installation groove 7 will also be inclined accordingly, and the angle between the surface where the LED lamp bead is installed and the flat reflective surface 5 is an acute angle, so that the light emitted to the flat reflective surface 5 can be increased, thereby further improving the working range of lighting brightness.

As shown in the figure, end plates 8 are provided at both ends of the reflector 4, and the end plates 8 are locked in the lamp cap housing 1 by screws, and the reflector 4 is pressed tightly on the lamp cap housing 1 of the reflector 4 through the end plates 8. Inside, the above structure not only fixes the reflector 4, but also the end plate 8 can reflect back the light leaked from the LED lamp beads to both ends, which improves the utilization rate of light and realizes a multi-purpose function.

As shown in the figure, the edge of the arc-shaped reflective surface 6 is provided with a side 9, and the lamp holder housing 1 is provided with a support plate 10, and the side 9 is supported by the support plate 10. The above-mentioned structure is convenient for positioning during installation and improves Accuracy and efficiency of installation.

As shown in the figure, the reflector 4 is provided with a plurality of cooling fins 11, which not only can dissipate heat to the air in the lamp holder housing 1 through the cooling fins 11, but also, the cooling fins 11 are arranged on the back of the reflector 4 and the lamp holder housing. In contact with the body 1, part of the heat can be conducted to the lamp cap shell 1 and dissipated into the external atmosphere through the lamp cap shell 1.
