Abstract

The utility model discloses a lamp with a lamp shade, comprising a lamp bulb 2, a lamp shade 1, a lamp holder 3 and an electric appliance portion 4. A reflector 5 is arranged between the lamp bulb 2 and the lamp shade 1, and the light rays that are emitted by the lamp bulb 2 and are projected to the upper part of the lamp shade 1 are reflected back to the area that needs to be illuminated by the reflector 5. The lamp with the lamp shade reduces the consumption of the light rays transmitted by the lamp shade 1, and the light rays emitted by the lamp bulb 2 are comparatively fully projected to the area that needs to be illuminated. The lamp with the lamp shade improves the illumination intensity of the lamp, and improves the availability ratio of the electric energy.

Description

The light fixture of band lampshade

Technical field

The utility model relates to a kind of light fixture with lampshade.

Background technology

The light fixture that has lampshade, as shown in Figure 1, the zone that utilizes the reflection of lampshade 1 to make light concentrate directive to throw light on relatively, guarantee certain illumination, but when lampshade 1 when being translucent or transparent, if any light fixture adopts is the PC cover, like this, the light of directive lampshade 1 is some zone that is reflected and throws light on to needs of light on directive lampshade 1 top particularly, another part to the zone that does not need to throw light on, as shown in Figure 2, has caused meaningless electric energy loss through lampshade 1 transmission, thereby reduced utilization rate of electrical, can't make full use of the light that bulb 2 sends and improve illumination.

The utility model content

The purpose of this utility model can make full use of the light fixture that light that bulb sends improves the band lampshade of illumination with regard to being to provide a kind of.

For reaching above-mentioned purpose, solution of the present utility model is:

A kind of light fixture of the band lampshade of being made up of bulb, lampshade, lamp socket and electrical appliance part also is provided with reflector between bulb and the lampshade, reflector is hood-shaped, and the reflecting surface of reflector is towards bulb.

Adopt such structure, the light on the directive lampshade top that bulb the sends zone that the device reflected back need throw light on that is reflected, reduced the loss of light through the lampshade transmission, make light that bulb the sends zone that need throw light on of directive more fully, improve illumination thereby can make full use of the light that bulb sends, improved utilization rate of electrical.

The utility model is described in more detail below in conjunction with the drawings and specific embodiments.

Description of drawings

Fig. 1 is the schematic diagram of the light fixture of prior art band lampshade.

Fig. 2 is the part light path schematic diagram of the light fixture of prior art band lampshade.

Fig. 3 is the schematic diagram of the light fixture of the utility model band lampshade.

Fig. 4 is the part light path schematic diagram of the light fixture of the utility model band lampshade.

Specific embodiment

Fig. 3 to Fig. 4 has provided a kind of specific embodiment of the light fixture of the utility model band lampshade, it is made up of bulb 2, lampshade 1, lamp socket 3 and electrical appliance part 4, also be provided with reflector 5 between bulb 2 and lampshade 1, reflector 5 is hood-shaped, and the reflecting surface of reflector 5 is towards bulb 2.Like this, the light on directive lampshade 1 top that bulb 2 the sends zone that device 5 reflected backs need throw light on that is reflected, reduced the electric energy loss that light produces through lampshade 1 transmission, make light that bulb 2 the sends zone that need throw light on of directive more fully, improve illumination thereby can make full use of the light that bulb sends.Obviously, the reflection efficiency of reflector 5 is high more, the illumination of this light fixture is just high more, therefore, the inner surface of reflector 5 is provided with the reflecting layer to improve reflection efficiency, in this case, aforesaid reflecting surface is exactly the inner surface in reflecting layer, this reflecting layer can be the reflectance coating that applies on the inner surface of reflector 5, when reflector 5 adopts metal material such as aluminium to make, can polish oxidation to its inner surface and form the reflecting layer.Through actual measurement, adopted the light fixture behind the reflector 5, when bulb 2 adopts 250W, compare the light fixture that does not adopt reflector 5 and can improve illumination and reach more than 50%, adopt 400W with bulb 2 but do not adopt the illumination of light fixture of reflector 5 suitable.

Claims

1, a kind of light fixture with lampshade, form by bulb (2), lampshade (1), lamp socket (3) and electrical appliance part (4), it is characterized in that: also be provided with reflector (5) between described bulb (2) and the lampshade (1), reflector (5) is hood-shaped, and the reflecting surface of reflector (5) is towards bulb (2).

2, the light fixture of band lampshade according to claim 1 is characterized in that: the inner surface of described reflector (5) is provided with the reflecting layer.

3, the light fixture of band lampshade according to claim 2 is characterized in that: described reflecting layer is the reflectance coating that applies on the inner surface of reflector (5).

4, the light fixture of band lampshade according to claim 2 is characterized in that: described reflecting layer is that the inner surface of reflector (5) polishes the oxide layer that oxidation forms.
