Description

a lighting fixture

technical field

The utility model relates to a lighting fixture, in particular to a multifunctional lighting fixture with improved structure.

Background technique

Existing lighting fixtures can be generally divided into two categories with regard to their lighting conditions during use. One is the diffuse lighting that illuminates the surroundings through the lamp head's own light emission-such as common indoor lights, which are used for large-scale lighting or all-round lighting. The other is to make the light from the lamp head form a beam of directional illumination by means of a reflective concentrating device or/and a refracting concentrating device, such as a flashlight, for small-scale illumination in a certain direction. In addition, compared with the first lighting method, the light intensity in the unit space of the second lighting method is higher, and can illuminate a longer distance.

Generally, people only need one of the above two lighting methods. However, there are occasions where changes in lighting conditions may be required due to changing conditions. At this time, it is often necessary to use different lamps to meet the lighting requirements, which is not convenient enough.

Utility model content

The purpose of this utility model is: aiming at the problems existing in the prior art above, to propose a multi-functional lighting fixture which can realize diffuse lighting and directional lighting respectively through simple conversion of itself, so as to meet different requirements for lighting states and provide User convenience.

In order to achieve the above purpose, the lighting fixture of the present utility model comprises a housing, a lamp holder located in the housing and electrically connected to a power supply through a switch, and a lamp holder arranged on the lamp holder, a lamp holder connected to the housing and surrounding The lampshade of the lamp holder is characterized in that: the lampshade is composed of an upper lamp bowl, a middle light-transmitting cover and a lower installation part connected to the housing. The installation part has at least a first and a second working position. When the lampshade is in the first working position , the lamp bowl is located around the lamp cap, and when the lampshade is in the second working position, the light-transmitting cover is positioned around the lamp cap.

In this way, when the lampshade is in the first working position, that is, when the lamp bowl is around the lamp head, under the action of the reflection and spotlight of the lamp bowl, a directional light beam can be emitted from the mouth of the bowl, thereby meeting the needs of directional lighting; The mechanism makes the lampshade in the second working position, that is, when the lamp head is basically located in the middle of the light-transmitting casing, the light emitted by the lamp head scatters to the surroundings through the casing, thereby meeting the requirement of diffuse lighting.

It can be seen that, after adopting the utility model, the user can simply adjust the position of the lampshade and the shell, and select diffuse lighting or directional lighting as required, without changing the lamp, and one thing is multi-purpose, which is very convenient.

Detailed ways

The basic structure of the multifunctional lighting fixture in preferred embodiment 1 of the present utility model is shown in Fig. 1-3. The shell 10 is cylindrical, the lower end is installed on the bottom socket 11 through a hinge shaft with a certain friction clamping force, the upper end is inserted into the lampshade, and the cylindrical lamp holder 6 electrically connected to the power supply through the switch 12 is fixed inside, and the lamp holder 6 Install lamp holder 1 on top.

The lampshade is composed of the lamp bowl 9 at the top, the circular tubular light-transmitting cover 2 at the middle and the installation site at the bottom. The lamp bowl 9 has a parabolic reflective surface. The specific structure of the installation part is shown in Figure 3, including the slider seat 3, the steel ball 4 and the spring 5. The outer circle of the upper end of the slider seat 3 is inserted into the lower end of the inner hole of the light-transmitting case 2 and fixed. The center of the slider seat 3 has a through hole that can pass through the columnar lamp holder 1. The lower part is formed with a radial hole, and the spring 5 is installed in the hole. Among them, steel ball 4 is arranged in the orifice. A limit bar 7 is fixed inside the housing 10, and the limit bar is formed with upper, middle and lower limit holes 8 (the limit holes can also be directly formed on the housing without installing another limit bar), thus forming Pull-out connection mechanism that can be adjusted and positioned in different positions.

When the lampshade is pulled upwards along the longitudinal direction of the cylindrical shell 10 until the steel ball 4 sinks into the upper limit hole under the action of the spring 5, the lamp holder 1 is positioned in the middle of the light-transmitting cover 2, and the light emitted by the lamp holder passes through after the power is turned on. The light-transmitting cover 2 scatters to the surroundings, which can meet the requirement of diffuse lighting (refer to FIG. 1 ). When the lampshade is pressed down along the longitudinal direction of the cylindrical shell 10 until the steel ball 4 sinks into the lower limit hole under the action of the spring 5, the lamp cap 1 is positioned at the focal point in the middle of the parabolic lamp bowl 9, and the light emitted by the lamp cap 1 after power on Under the action of reflection and light gathering of the lamp bowl 9, a directional light beam emitted from the mouth of the bowl is formed, which can meet the needs of directional lighting (see FIG. 2). When the steel ball 4 sinks in the middle limit hole, the light transmission area of the light transmission case decreases. In addition, when in use, the angle between the cylindrical housing 10 and the bottom socket 11 can also be adjusted according to the needs of different occasions, so as to change the lighting angle.

The multi-functional lighting fixture of preferred embodiment 2 of the present utility model is shown in Figure 4-7, and its basic structure and action effect are similar to embodiment 1, and the bottom socket 11' in the figure is inserted on the battery pack 13' as power supply. In Fig. 4, the lamp holder 1' is basically in the middle of the light-transmitting housing 2' to realize diffuse lighting; in Fig. 5, the lamp holder 1' is basically in the middle of the lamp bowl 9' to realize directional lighting.

The difference from Embodiment 1 is that the installation part of the lower part of the lampshade is composed of a nut 16' embedded and fixed at the lower end of the light-transmitting cover 2' and a threaded pin 15' screwed and fixed in the nut (the pin 15' is fixed at the lower end of the lampshade. can be). The upper end of the cylindrical housing 10' is equipped with an adjustment ring 14' that can rotate circumferentially relative to the cylindrical housing 10'. A spiral groove 17' is formed on the circumferential inner wall of the adjustment ring, and the protruding end of the latch 15' Insert into the spiral groove 17'.

When the adjustment ring is screwed relative to the cylindrical housing 10', under the interaction of the spiral groove 17' and the pin 15', the lampshade is at the upper and lower extreme positions relative to the cylindrical housing 10' along the longitudinal direction of the housing 10' Move between, so that the pull adjustment of the first embodiment is replaced by the rotation adjustment, which is also very convenient to operate.

For the structures and functions of other components, reference may be made to the description of Embodiment 1, and details are not repeated here.

It should be noted that the above-mentioned embodiments are non-restrictive, and all equivalent replacements or equivalent transformation schemes made by those skilled in the art to the preferred embodiments with reference to the spirit and concept of the present utility model all fall within the scope of protection required by the present utility model Inside.
