Embodiment Construction

[0018] refer to figure 1 with figure 2 The reflective LED bar lamp includes a lamp body main body 1 , a bracket 5 , a light source part mounted on the bracket, a circuit board 13 electrically connected to the light source part, a heat dissipation part and a power source 8 .

[0019] The main body 1 of the lamp body is a metal frame body, which is a substantially L-shaped plate stamping part. figure 2 As shown in , the L-shaped plate of the main body of the lamp body becomes the back plate and bottom plate of the ground bar lamp. A folded portion parallel to the bottom plate is formed on the top of the back plate. A plurality of cooling holes are stamped on the folded part and the bottom plate respectively.

[0020] The light source part specifically includes an LED light source 15 , a substrate 14 , a reflector 2 , and a side reflector 3 . Wherein, the reflector 2 is combined with the reflectors 3 on both sides to form a reflector. The side reflector 3 can be integrally...

Abstract

The invention discloses a reflection-type LED (light emitting diode) ground row which comprises a ground row main body, a supporting frame, a light source part, a heat dissipation part and a power supply, wherein the supporting frame is fixed on the ground row main body; the light source part is installed on the supporting frame; the heat dissipation part is installed on the ground row main body; the power supply is electrically connected with the light source part; the light source part comprises an LED light source, a substrate and a reflector; the LED light source is installed on the substrate; the substrate is fixed on the reflector; the lighting direction of the LED light source is towards the reflector; the light emitted within the high-intensity light ray range on the reflector is reflected to one side, close to the LED light source, of an irradiated object; and the light emitted within the low-intensity light ray range on the reflector is reflected to one side, far away from the LED light source, of the irradiated object, and the heat dissipation part is adhered to one side, far away from the reflector, of the substrate. The reflection-type LED ground row has the technical characteristics of large range of lighting and favorable heat dissipation.

Description

technical field [0001] The invention relates to a reflective LED floor bar light for film and television stage lighting, and belongs to the technical field of film and television stage lighting. Background technique [0002] Existing lamps usually see the light source from the front, and the greater the lamp power, the greater the luminous intensity. Various lamps have different light intensity according to different purposes. For example, street lighting needs to have a uniform area and a wide area. Landscape lighting and stage lighting need to be bright and colorful. There are many types of stage lighting, such as projection lights, spotlights, and floodlights. , Canopy lights, floor row lights, etc., especially in stage performances, the ground row lights must be matched with the background curtain to meet the requirements of stage lighting and achieve the desired effect of the performance. [0003] The ground row light is a kind of high-power astigmatism light, which is...
