Embodiment Construction

[0021] The present invention will be described in detail below with reference to the drawings and specific examples.

[0022] Such as figure 1 As shown, this embodiment provides a dimmable linear LED floodlight, which can be applied to lighting and decoration in various occasions, using the principle of three-primary color ratio mixing and adopting different color temperature segments By controlling and adjusting the light source, you can sensitively adjust the lighting effect, and adjust the lighting area and height of the lamp.

[0023] Such as figure 2 As shown, in this embodiment, the linear LED projection lamp includes a driving board 108, an LED light source 107 and a housing assembly. Each LED light source 107 is installed and fixed on the light source board, and the driving board 108 and the LED light source board are both installed and fixed inside the lamp housing , The driving board 108 controls each LED light source 107 to emit light while adjusting the light effect of...

Abstract

The invention discloses a dimmable linear LED projection lamp, which includes a drive plate, an LED light source and a casing assembly. According to the design, the drive plate is provided with an RS485 network bus, a singlechip microprocessor, a constant current drive chip, and a feedback detection circuit module; the casing assembly includes an upper casing, a bottom casing, a middle frame and a lampshade, which are combined mutually, wherein the lampshade comprises a double-closing / opening light baffle plate locked and fixed with an upper cover; a rotatable mechanism is designed, so as to regulate the light-emitting area and the emergent light angle; according to the design, the drive plate is provided with circuits corresponding to the RS485 transmismission and standard DMX (data mining extensions) protocols; and standard DMX512 data packages are sent and received through an RS485 network, and PWM (pulse width modulation) signals are generated via decoding and data conversion and are controlled and output through the constant current drive chip, so that the corresponding LED light source is driven. The dimmable linear LED projection lamp can regulate light effect, the regulating effect is good, the lamp irradiation area and irradiation height can be regulated, and the regulation is convenient and rapid.

Description

Technical field [0001] The invention relates to an environment-friendly and energy-saving lighting device, in particular to a dimmable linear LED projection lamp. Background technique [0002] LED flood light is also known as wall washer, flood light, etc. It is mainly used in the main decorative lighting and auxiliary lighting in indoor and outdoor fields. For example, it is applied to outdoor buildings, three-dimensional walls, squares, sports fields, stages, bridges, building curtain walls, gardens and other places. Another example is used in indoor shopping malls, dance halls, bars, stadiums, buildings, etc. [0003] In the prior art and on the market, the light-emitting area of ​​LED floodlights is fixed and invariable. Once the lamp is manufactured and formed, its illumination area or light output angle cannot be adjusted, and the light effect of LED floodlights needs to be set in advance, if required in different occasions The application needs to be adjusted, and it needs...
