In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Fig. 1 shows a luminaire of an embodiment of the invention. Fig. 2 is a cross-sectional view of a lamp according to an embodiment of the invention. As shown in fig. 1 and 2, the present invention relates to a lamp 100 including a light emitting element 1, a mount 7, a housing 2, and a first elastic heat conductive member 3. Wherein the light emitting element 1 is fixedly arranged on the mount 7. The mounting member 7 is provided in the housing 2, and an adjustment gap is formed between the mounting member 7 and the housing 2. The first elastic heat conductive member 3 is disposed in the adjustment gap and abuts against the mount 7 and the housing 2. The light emitting element 1 is preferably but not limited to a light emitting chip. The lamp of this embodiment is preferably a spotlight for a museum or exhibition hall, and may be other lamps with an adjusting gap.
As can be seen from the above-mentioned technical solutions, the lamp of the present embodiment mainly includes the first elastic heat conductive member 3 between the mounting member 7 and the housing 2, and the first elastic heat conductive member 3 is abutted against the mounting member 7 and the housing 2. This allows heat generated when the light emitting element 1 emits light to be transferred from the mounting member 7 to the housing 2 through the first elastic heat conductive member 3, so that the housing 2 also plays a role in heat dissipation, increasing the heat dissipation area of the lamp 100, thereby improving the heat dissipation effect of the lamp 100. Because the first elastic heat conducting piece 3 has elasticity, when the installation piece 7 and the shell 2 generate relative motion, the first elastic heat conducting piece 3 can stretch out and draw back under the action of external force, can be connected with the shell 2 and the installation piece 7 all the time, and can not hinder the relative motion between the shell 2 and the installation piece 7. In addition, the lamp 100 of the embodiment has the advantages of simple structure, easy manufacture, safe and reliable use and convenient implementation, popularization and application.
The lens 9 is preferably provided on the housing 2 and opposite to the light emitting element 1. The operator can change the distance between the lens 9 and the light emitting chip by pushing and pulling the housing 2, thereby focusing the lamp 100. The housing 2 and the mounting member 7 are preferably both made of a heat conductive material, and the mounting member 7 is preferably a metal heat sink, so as to further enhance the heat dissipation efficiency of the lamp 100.
The first elastic heat conductive member 3 is preferably, but not limited to, made of a heat conductive metal such as copper, silver, or aluminum. In this embodiment, the first elastic heat conductive member 3 is a spring. The spring is sleeved on the mounting piece 7. Because the support direction of the spring is parallel to the extending direction of the mounting piece 7, the mounting piece 7 is connected with the shell 2 by the spring, so that heat in the mounting piece 7 can be conducted into the shell 2, the shell 2 can be guided, the adjusting precision of the shell 2 can be improved, and the focusing precision of the lamp 100 can be improved.
Preferably, in this embodiment, as shown in fig. 3, the spring is a first lantern spring, a first circumferential ring groove 71 is formed on the outer circumferential wall of the mounting member 7, the first lantern spring is disposed in the first circumferential ring groove 71, and the middle part protrudes outwards and abuts against the housing 2. Or the inner peripheral wall of the shell 2 is provided with a first peripheral ring groove 71, the first lantern spring is arranged in the first peripheral ring groove 71, and the middle part of the first lantern spring is inwards recessed and abuts against the mounting piece 7. The first lantern spring can be contacted with the casing 2 or the mounting 7 through a plurality of elastic strips that distribute along circumference, and the first lantern spring can be when compressed with axial pressure turn into radial holding power to carry out more inseparable contact with mounting 7 and casing 2, have better heat conduction effect. At the same time, the first lantern spring is able to provide a damping effect for the sliding between the mount 7 and the housing 2. Since an operator generally changes the relative distance between the lens 9 and the light emitting element 1 by pushing and pulling the housing 2 during focusing of the lamp 100, the position of the mounting member 7 is relatively fixed, and when the first circumferential ring groove 71 is formed on the mounting member 7, the mounting member 7 can more reliably limit the first lantern spring, so that the first lantern spring is not easy to fall off due to sliding.
In this embodiment, the luminaire 100 further comprises a swivel ball 4 and an annular base. The rotary ball head 4 is arranged outside the shell 2 in a surrounding mode, an avoidance opening is formed in the shell 2, the rotary ball head 4 is detachably connected with the mounting piece 7 through the avoidance opening, and an accommodating gap is formed between the rotary ball head 4 and the shell 2. An arcuate surface is formed on the inner peripheral wall of the annular base, the arcuate surface being adapted to receive the rotary ball 4 for rotation therein. The annular base can be used for installing the lamp 100 at a proper position, and an operator can drive the rotary bulb 4 to rotate relative to the annular lamp holder, so that the lamp 100 irradiates different angles by carrying the installation piece 7 and the luminous element 1 connected with the rotary bulb. The second elastic heat conductive member 6 is disposed in the accommodation gap and abuts against the rotary ball 4 and the housing 2. The heat on the housing 2 can be transferred into the swivel ball 4 through the second elastic heat conducting member 6, thereby further increasing the heat radiating area of the lamp 100. The second elastic heat conductive member 6 is preferably, but not limited to, made of a heat conductive metal such as copper, silver, or aluminum. In this embodiment, the second elastic heat conductive member 6 is a spring. The spring is sleeved on the shell 2. The swivel ball 4 and the housing 2 are optionally connected by means of fasteners, preferably in this embodiment the swivel ball 4 is screwed with the housing 2.

At the same time, the second lamp housing spring can also provide a damping effect for sliding between the housing 2 and the mounting 7.
Because when the operator needs to focus on the lamp 100, the housing 2 is generally pushed or pulled, the position of the rotating ball 4 is relatively fixed, and when the second circumferential ring groove 41 is formed on the rotating ball 4, the rotating ball 4 can more reliably restrict the position of the second lantern spring, so that the second lantern spring is not easy to fall off in the sliding process. In addition, first lantern spring and second lantern spring can mutually support to play righting effect to casing 2, avoid casing 2 to take place the slope at the slip in-process, lead to taking place to collide with installed part 7 or rotatory bulb 4, help promoting user experience, and prolong the life of lamps and lanterns 100.

Wherein, the arc surface is formed on the mounting cylinder 51, and the opening diameter of the lower end of the mounting cylinder 51 is smaller than the maximum outer diameter of the rotary ball head 4. And a limiting ring 52 detachably connected to the upper end of the mounting cylinder 51 and positioned above the rotary ball 4, the limiting ring 52 having an inner diameter smaller than the maximum outer diameter of the rotary ball 4. The installation of the rotary ball head 4 can be facilitated and the reliable constraint can be implemented on the rotary ball head 4 through the cooperation of the installation cylinder 51 and the limiting ring 52. The mounting barrel 51 and the stop collar 52 may be removably attached or adhered to each other by fasteners, preferably in this embodiment, the mounting barrel 51 is threadably attached to the stop collar 52. Preferably, the upper side of the stop collar 52 is formed with a flare 521. The inner diameter of the bell mouth 521 is gradually increased along the direction away from the rotary ball head 4, the bell mouth 521 can play a role in avoiding interference between the shell 2 and the limiting ring 52 in the process of rotating the rotary ball head 4, and the rotating angle of the lamp 100 is increased.

The lamp 100 further comprises a first elastic sealing ring 81 sleeved on the shell 2 and located in the third circumferential ring groove 42. The first elastic sealing ring 81 can improve the tightness of the lamp 100, and can avoid collision between the rotary ball head 4 and the arc-shaped surface, so that the rotary ball head 4 rotates in the arc-shaped surface more smoothly. A fourth circumferential ring groove 511 is formed between the rotary ball 4 and the mounting ring, and the lamp 100 further includes a second elastic sealing ring 82 sleeved on the rotary ball 4 and located in the fourth circumferential ring groove 511.
