Description

a desk lamp

technical field

The utility model belongs to a lamp for lighting, in particular to a desk lamp.

Background technique

In the prior art, there are many kinds of lamps traditionally used for lighting, which are generally classified into incandescent lamps, tungsten-halogen lamps, fluorescent tubes, halogen lamps, gas discharge lamps and the like according to different uses. But above various light fixtures also have such or such shortcoming while having some unique advantages respectively. For example, incandescent lamps have low luminous efficiency; due to the working principle of tungsten-halogen lamps, the temperature of the inner wall of the bulb must be kept above 250°C, which makes the lamps hot and easy to burn; fluorescent tubes contain mercury and ultraviolet light, which has a certain degree of damage to the environment , and requires high-voltage drive, which is likely to cause safety problems; both halogen lamps and gas discharge lamps contain ultraviolet light, which is harmful to the human body, and also require high-voltage drive. They need to be preheated when starting, and need to cool down before restarting after power interruption. etc. In addition, a common disadvantage of the above-mentioned various lamps is that their lifespan is relatively short, and all of them use glass casings, which are easily affected by vibration, fragile, and prone to danger.

Utility model content

The purpose of the utility model is to provide a desk lamp, which adopts a light-emitting diode as a light source, and has the advantages of energy saving, safety, long service life and soft light.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a table lamp, including a light source, a lamp body and a base, the light source is composed of a light emitting diode module and a lampshade, and the light emitting diode module is placed in the lampshade.

More preferably, the light-emitting diode module is surrounded by a frame, including a circuit board layer and a light-emitting diode chip, the light-emitting diode chip is installed on the circuit board layer, a phosphor layer is filled between the light-emitting diode chip and the circuit board layer, and the phosphor layer Sealed with silica gel.

More preferably, the lampshade is composed of an upper lampshade, a lower lampshade and a transparent cover, and the lower lampshade is provided with a groove matching the LED module.

More preferably, a turning head is provided between the light source and the lamp body, and the light source and the lamp body are connected through the turning head.

And, the lamp body is composed of an upper rod and a seat post hinged, and a control button is arranged on the seat post.

Because the utility model applies the light-emitting diode module to the desk lamp, and adopts the light-emitting diode as the light source, there is no flicker, no ultraviolet and infrared radiation, so the light is soft; because the light-emitting diode module adopts a high-quality light-emitting diode chip, the power of the desk lamp It is small, energy-saving, and has a long service life, but the brightness of the light emitted has reached the standard for desktop reading.

Detailed ways

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

As shown in Figure 1 and Figure 2, the utility model discloses a desk lamp, comprising a light source 1, a lamp body 2 and a base 3, the light source 1 is composed of a light emitting diode module 11 and a lampshade 12, the lampshade 12 is composed of an upper lampshade 121, a lower lampshade 122 and a transparent cover 123, the light emitting diode module 11 is fastened in the lamp cover 12 through the matching groove 124 on the lower lamp cover 122.

Wherein, the LED module 11 is surrounded by a frame 111, as shown in FIG. 3 , including a circuit board layer 112 and an LED chip 113. The phosphor layer 114 is filled, and the phosphor layer 114 is sealed by silica gel 115 . The uniform filling of the fluorescent powder improves the luminous efficiency of the diode, and the color temperature is uniform, the light is uniform and soft, and the manufacturing process is simple and the production cost is low.

The light source 1 and the lamp body 2 are connected through a turning head 4, as shown in FIG. 1 . The lamp body 2 is composed of an upper rod 21 and a seat post 22 hinged, and the seat post 22 is provided with a control button 23 .

The utility model applies the light-emitting diode module to the table lamp, and adopts the light-emitting diode as the light source, so there is no flicker, no radiation and soft light; because the light-emitting diode module adopts a high-quality light-emitting diode chip, the power of the table lamp is small, energy-saving, and easy to use. It has a long lifespan, but the brightness of the light emitted has reached the standard of desktop reading.

The above is only the preferred embodiment of the utility model, it should be pointed out that, for those of ordinary skill in the art, without departing from the inventive concept of the utility model, some deformations and improvements can also be made. Belong to the protection scope of the utility model.
