Technical Field

The utility model relates to a LED lamp area equipment technical field, concretely relates to diffuse reflection lamp strip of DC30V power supply.

Background

An LED (light emitting diode) is called a fourth generation illumination light source or a green light source, has the characteristics of energy saving, environmental protection, long service life, small volume and the like, and is widely applied to the fields of various indications, display, decoration, backlight sources, general illumination, urban night scenes and the like. In practical production application, the LEDs are generally based on modularization and flexible design, that is, a certain number of LEDs (light emitting diodes) are arranged together according to rules and then packaged, and some waterproof processing is performed to form a module product, so that the module product is more and more favored by people due to the advantages of convenience in production, convenience in assembly, convenience in replacement and the like. In an LED module product, sometimes, in order to make light emitted by the product softer and more uniform, a lens is added in the product to manufacture a diffuse reflection module product, and the light is scattered by utilizing the refraction effect of the lens on the light, so that the light emission of the product is more uniform; such as low voltage diffuse reflector light bars or strips. The conventional low-voltage diffuse reflection lamp bar is generally powered by DC12V, the output voltage is low, and the loss voltage of a wire is high, so that the more the connection quantity is, the larger the voltage drop of the tail end is; in practical use, when 20 diffuse reflection lamp bars powered by DC12V are connected, the voltage at the tail end is only about 10.5V, 1.5V voltage is lost, the voltage has obvious influence on the brightness of the lamp beads, and the brightness of the lamp beads is weakened when the voltage is reduced; in order to ensure the uniformity of the brightness of the light bar, when the diffuse reflection light bar powered by the DC12V is used, a power supply is generally connected to the tail end of the light bar; this increases the consumption of the wire material, i.e. increases the material cost, and also increases the labor cost because of the need for multiple wiring.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: the diffuse reflection lamp bar with the DC30V power supply is provided, the voltage drop of the lamp bar product is small, the brightness of the lamp bar is not affected basically, the tail end of the lamp bar is not required to be connected with a power supply, the connection frequency of the lamp bar and the power supply can be effectively reduced, and the wire material and the labor cost are saved.

The technical scheme of the utility model is that: a diffuse reflection lamp bar powered by DC30V comprises a substrate and LED lamp beads electrically connected to the substrate, wherein the LED lamp beads are 9V lamp beads, and each 3 LED lamp beads are connected with a resistor in series to form a light-emitting unit; the light bar is powered by a DC30V power supply.

Further, there are a plurality of light emitting units on the substrate, and preferably, the number of light emitting units on the substrate is an even number, for example, the number of light emitting units may be 2, 4, etc.

Furthermore, every two light-emitting units on the substrate share one group of interfaces connected with a power supply.

Further, LED lamp pearl is provided with lens, and what lens adopted is astigmatic structure, can be 162 half light intensity angle with the 120 half light intensity angle diffusion that LED sent, and the mixed light distance reduces, and then makes the thickness of lamp strip can be littleer.

Further, the outline of the lens in a plan view is a circular arc or a regular polygon, for example, a triangle, a square, a circle, an ellipse, or the like.

Further, the substrate is a long and straight strip, preferably, the substrate can be an arc strip, so that the substrate is better adapted to the installation environment.

Furthermore, the substrate can be a composite material plate which is formed by bonding a boron nitride layer, an insulating glue layer and a graphite plate, so that the substrate has the characteristics of light weight, high endurance strength and difficulty in cracking.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a diffuse reflection lamp strip adopts per 3 LED lamp pearls and a resistance series connection to form a luminescence unit, and LED lamp pearl uses 9V lamp pearl, and the outside adopts DC30V mains operated, compares in the lamp strip that adopts DC12V mains operated, and the pressure drop is little, and light luminance is even, and the end need not connect the power, has saved material cost and cost of labor.
