The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment:

The utility model embodiment provides a kind of stage lighting lighttight heat abstractor, in conjunction with Fig. 1, Fig. 2 and shown in Figure 3, the lighttight heat abstractor of a kind of stage lighting, the fixed mount 1 and the polylith heat sink 2 that comprise hollow, described heat sink 2 comprises front panel 21 and rear board 22, described front panel 21 is 45 °～135 ° angles with rear board 22 and is fixedly connected with, all heat sinks 2 are arranged and are fixed on the two side of fixed mount 1 from top to bottom, described front panel 21 and rear board 22 tilt simultaneously up or down, form the heat dissipation channel 20 of V-arrangement between the two adjacent heat sinks, the upper wall of fixed mount (upper bracket) 11, lower wall (lower carriage) 12 contacts with undermost heat sink with the heat sink of the superiors respectively.

The front panel of heat sink described in the utility model embodiment is 90 ° of angles with rear board and is fixedly connected with, can make like this heat sink be more convenient for arranging, and the passage length that can guarantee heat dissipation channel is unlikely to long, and can add more heat dissipation channel at fixed mount, realize better radiating effect.Certainly, if select the front panel of heat sink to be fixedly connected with the angle of rear board angle at 45 °, the quantity of heat dissipation channel is reduced relatively, but can strengthen the performance of light leakage, if select the front panel of heat sink to become 135 ° of angles to be fixedly connected with the angle of rear board, the quantity of heat dissipation channel is increased relatively, but the leakproof effect of light can relative reduce.

Because heat abstractor is mounted on the lamp housing of stage lighting, it is in the face of light source, therefore described front panel and rear board few light that tilts can guarantee to try one's best up or down simultaneously is injected into the forward part of heat dissipation channel, even and have small part light to be injected into the forward part of heat dissipation channel, because heat dissipation channel is crooked, this light still can't penetrate heat dissipation channel, realizes the leakproof effect of light.The front panel of heat sink is downward-sloping among the utility model embodiment, therefore rear board is also downward-sloping, the heat dissipation channel that two adjacent heat sinks consist of then is an inverted V-shaped passage, air can be by this heat dissipation channel circulation, take away heat, but light has guaranteed that namely heat radiation has realized again light leakage owing to then can't spread out of this heat dissipation channel along straightline propagation.Certainly, if the front panel of heat sink is inclined upwardly, then the rear board of heat sink also is inclined upwardly simultaneously, and the two adjacent formed heat dissipation channels of heat sink are the V-arrangement heat dissipation channel.

Be understandable that heat sink is arranged from top to bottom, need to contact to realize the leakproof effect of light with the upper wall of fixed mount at the heat sink of the superiors, same, also need to contact to realize the leakproof effect of light with the lower wall of fixed mount at undermost heat sink.The heat sink of the superiors contacts with the upper wall seamless of fixed mount, and undermost heat sink contacts with the upper wall seamless of fixed mount, does not have like this light leak gap between fixed mount and the heat sink, can better realize the leakproof effect of light.In order further to realize the leakproof effect of light, fixed mount described in the utility model embodiment is fixedly surrounded by upper bracket 11, lower carriage 12, left socle 14 and right support 13, all heat sinks are fixed between left socle 14 and the right support 13, upper bracket 11 is L shaped shadow shield with lower carriage 12, the front end of upper bracket downwards bending contacts with the heat sink of the superiors, and the front end of lower carriage upwards bending contacts with undermost heat sink.
