Example one

A telescopic lamp as shown in fig. 1-13 comprises a lamp handle 1, a first bracket 2, a second bracket 4, a first light-emitting member 3, a second light-emitting member 5, a first housing 8 and a second housing 9. The first bracket 2, the second bracket 4, the first light-emitting component 3, the second light-emitting component 5, the first shell 8 and the second shell 9 are all strip-shaped and have the same extending direction.

In this embodiment, one end of the first bracket 2, the first light emitting element 3 and the first housing 8 are all fixedly connected to an end surface of the lamp holder 1, an accommodating gap is formed between the first light emitting element 3 and the first bracket 2, and the first housing 8 is sleeved on the peripheries of the first bracket 2 and the first light emitting element 3. The second support 4 is connected to the first support 2 in a sliding mode along the length extending direction of the first support 2, the second light-emitting piece 5 is installed on the second support 4 and arranged in a staggered mode with the first light-emitting piece 3, the second shell 9 is sleeved on the peripheries of the second support 4 and the second light-emitting piece 5, and the second shell 9 is connected with the first shell 8 in a sliding mode and is embedded in the first shell 8.

In the process of relative sliding between the second bracket 4 and the first bracket 2, the second bracket 4 has a contracted state in which it is stacked with the first bracket 2 such that the second luminous element 5 and the first luminous element 3 are stacked, and an extended state in which it is extended outward relative to the first bracket 2 such that the second luminous element 5 and the second luminous element 5 are sequentially disposed along the length direction of the first bracket 2. When the second bracket 4 is in the contracted state, the second light-emitting member 5 is placed in the accommodating gap and shielded by the first light-emitting member 3.

According to the telescopic lamp with the structure, the second support 4 and the first support 2 extend in the same direction and are connected in a sliding mode, and the second light-emitting piece 5 and the first light-emitting piece 3 are arranged in a staggered mode, when the lamp is required to have a long illumination length in the using process, the second support 4 is slid to the extending state, and the first light-emitting piece 3 and the second light-emitting piece 5 are arranged in sequence, so that the illumination length requirement of the lamp can be met; when taking in, the second bracket 4 slides to the retracted state, the second light-emitting part 5 and the first light-emitting part 3 are arranged in a stacked mode, the overall length of the lamp (especially some strip-shaped lamps) can be shortened, correspondingly, the length of the box body required for taking in the lamp is shortened, and the lamp is convenient to carry.

In the embodiment, the circuit on the first light-emitting element 3 is connected with the power supply circuit, and a trigger mechanism for controlling the connection or disconnection of the circuit on the second light-emitting element 4 and the power supply circuit is arranged between the first light-emitting element 3 and the second light-emitting element 5; when the second bracket 4 is in the extending state, the triggering mechanism is triggered to make the circuit on the second luminous element 5 be communicated with the power supply circuit; when the second support 4 is in the retracted state, the trigger mechanism is opened to disconnect the electrical circuit on the second glowing member 5 from the power supply circuit. Specifically, the trigger mechanism comprises a first electrical contact 301 arranged on the first light-emitting element 3 and a second electrical contact 501 arranged on the second light-emitting element 5; when the second bracket 4 is in the extended state, the second electrical contact 501 contacts with the first electrical contact 301 to connect the circuit on the second light emitting element 5 with the circuit on the first light emitting element 3, and after the lamp is started, the first light emitting element 3 and the second light emitting element 5 can be simultaneously energized to emit light. When the second bracket 4 is in the contracted state, the second electrical contact 501 is separated from the first electrical contact 301, and only the first light-emitting component 3 is electrified to emit light after the lamp is started, so that the lamp can be electrified to emit light in the shortened state. Therefore, the lamp has two different illumination lengths in the two states of shortening and extending, the problems that the illumination length of the lamp is single and cannot be adjusted in the prior art are solved, and the practicability is higher. In addition, the first light emitting element 3 is provided with a third contact 302, when the second bracket 4 is in a contracted state, the second electrical contact 501 is in contact with the third contact 302, but at this time, the circuit on the second light emitting element 5 is not communicated with the circuit on the first light emitting element 3, and the third contact 302 only plays a role in protecting the second electrical contact 501.

In this embodiment, a cavity is arranged inside the second bracket 4 along the length extension direction of the second bracket, and the first bracket 2 is slidably connected in the cavity of the second bracket 4; when the second bracket 4 is in a contracted state, the first bracket 2 is completely accommodated in the cavity of the second bracket 4; when the second support 4 is in the extended state, the first support 2 extends outwardly from the cavity. First support 2 sliding connection is favorable to keeping the straightness accuracy of second support 4 slip in-process in the cavity of second support 4, improves first support 2 and second support 4 and takes place the stability of relative slip in-process, and then is favorable to the reliability of contact between the electric contact on the second illuminating part 5 and the electric contact on the first illuminating part 3.

In this embodiment, the second support 4 is a long cylindrical structure with a semicircular cross section, the cross section of the cavity in the second support 4 is also semicircular, the first support 2 is a long cylindrical structure with a semicircular cross section, and the cross section of the first support 2 is the same as the cross section of the cavity in the second support 4 in shape and size, so as to facilitate the sliding fit of the first support 2 and the second support 4. In other alternative embodiments, the cross-section of the lumen in the second stent 4 may also be circular or polygonal, and accordingly, the cross-section of the first stent 2 may be maintained in the same shape and size as the cross-section of the lumen in the second stent 4. The inside of first support 2 also is equipped with the installation cavity, and the installation cavity can provide installation space for parts such as lamps and lanterns power, and then reduces the length requirement to lamp handle 1, is favorable to further shortening the whole length of accomodating of lamps and lanterns.

In the embodiment, because the first bracket 2 is closer to the lamp handle 1 than the second bracket 4, in order to facilitate the arrangement of the internal circuit of the lamp, the power supply of the lamp is only suitable to be installed in the installation cavity of the first bracket 2, and the installation space inside the first bracket 2 is partially occupied; compare with the inside technical scheme of second support 4 nestification in first support 2, the installation cavity of the unable complete indentation first support 2 of second support 4 with the same length of first support 2 in results in the holistic length of accomodating of lamps and lanterns still longer, if adopt shorter second support 4, again influences the illumination length of lamps and lanterns.
