Reflection cup fixing structure and searchlight

Abstract

The invention is directed to a field of lighting technologies, and provides a reflection cup fixing structure used for fixing the reflection cup on a lamp housing of a light fixture. The fixing structure comprises: a retainer ring, wherein the retainer ring is fixedly connected with a non-reflection side of the reflection cup; at least a first fixing plate, a second fixing plate, a third fixing plate and a fourth fixing plate; at least three sets of damping bolts and nuts; and at least a first connection board and a second connection board. The non-reflecting surfaces of the retainer ring and the reflection cup are bonded. One ends of the first fixing plate and the second fixing plated are respectively connected with the retainer ring, and one end of the third fixing plate is connected with the retainer ring while the other end of the third fixing plate is connected with the fourth fixing plate. A searchlight is also provided, which comprises the lamp housing, the reflection cup and a light source unit, wherein the reflection cup is fixed on the lamp housing by the reflection cup fixing structure. The searchlight with the reflection cup fixing structure has a stable structure and good anti-shocking performance.

Description

technical field [0001] The invention belongs to the technical field of lighting, and more specifically relates to a reflective cup fixing structure and a searchlight adopting the reflective cup fixing structure. Background technique [0002] Usually, the light energy of the light source will be fully radiated in a 360° direction. In order to effectively utilize the limited light energy, the lamp can control the illumination distance and illumination area of ​​the main spot through the light reflector. Especially for a single point light source, the directionality of its light is very poor. If no corresponding light distribution measures are taken, the loss of light will be great, especially for lamps like searchlights, which require more concentrated light.

AI Technical Summary

Problems solved by technology

Especially for a single point light source, the directionality of its light is very poor. If no corresponding light distribution measures are taken, the loss of light will be great, especially for lamps like searchlights, which require more concentrated light. To meet the needs of long-distance irradiation, it is necessary to install reflectors such as reflectors in the lamps to achieve the purpose of gathering light and changing its irradiation direction

At the same time, outdoor lamps such as searchlights are generally installed in higher positions, and may often encounter storms or other vibrations. If the reflector vibrates strongly, good lighting effects cannot be obtained. Significantly higher requirements for shock resistance

[0003] However, due to the special structure of the reflector, the reflector of the existing lighting fixtures is generally fixed in the inner cavity of the lamp or on the back cover of the lamp by bolts or pressure sheets. After the reflector is fixed, there is basically no room for adjustment, which belongs to the rigid fixing method.

In general long-distance projection lights, especially searchlights, the reflector needs to reflect the light as much as possible to obtain the required long-distance lighting. Therefore, the reflection area of ​​the reflector is usually relatively large and the weight is relatively heavy. The method of pressing and fixing the reflector cup with bolts or pressing sheets is very inconvenient when assembling the lamp. Usually, the long-distance projection lamp has a long lamp body. Although the reflector is easy to assemble when it is installed on the back cover, it is not suitable to be fixed by traditional bolts or pressing pieces, and cannot be used in places with strong vibrations.
