The lighting effect is still relatively single, and it is difficult to show variable lighting effects when the stage light rotates.

Utility model content

In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a two-way light-emitting computer stage light. Two sets of light source assemblies on the same axis and with opposite light-emitting directions are arranged on the lamp head assembly, so that the stage light Straight lines are always present when irradiating or directional irradiating.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

Provided is a two-way light-emitting computer stage light, including a lamp holder, a bracket arranged on the lamp holder, a lamp head assembly and a control system for controlling the operation of the lamp head assembly. The lamp head assembly is rotatably connected to the bracket. For the light source assemblies set on the same axis, the two sets of light source assemblies emit light in opposite directions, and the control system controls the illumination of the two sets of light source assemblies respectively.

As a fourth improvement, the lamp holder is provided with a position sensor that automatically detects the light emitting direction of the light source assembly. Computer stage lights have certain requirements on the irradiation power of the light source.

Based on the above reasons, a position sensor is installed on the lamp holder to detect the light output direction of the light source assembly. When the position sensor detects that the light output of the light source assembly hits the bracket or the lamp holder, the residence time of the light source assembly does not exceed 3 seconds, avoiding The problem of high temperature damage to the bracket or lamp holder.
